Just thought I'd ask if the Martin turbo system will fit under a 3rd gen... some guys have said yes ,but you have to knock your towers and other guys say, if a big block can fit ,heck , anything will,..... then you got others who say, it was designed for a vette.... so anyway, my point is....... Have any of you guys or girls , put this system on... I'm looking at only wanting 5-6 psi boost, and I've got the vera-jection system to cool the charge... I know blow-thru is the way to go but , I'm just wanting a little more power than your normal old 350... It is a Pre-86 Block with 8.5 compression, with quadrajet setup... and I think it looks like it came from the factory with it... so , can anybody help me out or have pics of this setup... thanks

so, do they fit in a 3rd gen, I've done ordered a system, I noticed you had the truck version, The one I got is the vette version,I hope mine will fit... yours looks a little tighter..Space is a big concern with these..Do you have any pics of them in a trans am or camaro..3rd gen especially..Your engine looks freakin killer by the way.. I bet you get a lot of looks... anyway... Please let me know if you think this kit will fit or I'll sell it on ebay like I see or just keep it for future projects..thanks for the pics..

That turbo in the pic didn't have oil problems with the way the center section is clocked? Not more than 15* from vertical is the norm.
That one looks like around 45*. The oil return hole is smaller than 3/8" diameter at the block for the fuel pump. I wouldn't dump the return oil there. You might get away with it but at high RPM there should be too much oil for that size hole and it will come out the exhaust and maybe into the intake.

JoBy

I have not had any problems with my oil return. It is a bigger pipe but I also use a modified fuel pump block off plate.

You can see the pipe in some pictures here:

Just looking at it I doubt it will fit. The manifold will run straight into the crossmember.

RacerRick

The camaro kit will fit in a camaro. The kit that is shown looks like the truck kit and will not fit. There were three different SBC kits from Martin - Trucks, vettes, and the camaro kit.

The easiest way to tell the camaro kit is that the turbo is not angled like on the truck and vette kits. It points straight ahead. The turbo is also mounted closer to the front.

Truck kits have the turbo hanging out pretty far and centered on the exhaust manifold. I haven't seen a vette kit in person, but the pics I have show them with angled turbos like the truck kit, but they appear to be tucked in much closer to the front of the engine.

They made these kits and had CARB exemption for camaros up to 85'.

The cast oil return is supposed to point as close to straight down as possible and should just clears the turbo flange and manifold. Drainback is only by gravity and oil control is only by a couple of lip seals. My system points straight down and I have never had a problem.

I thought i read somewhere that the manifold will not clear the raised valvecover rail on centerbolt heads.

Honestly turbocharging has come along way since those kits. I would just invest into a BBS manifold and a blow through carb if your working on a budget.

RacerRick

Thats probably why they are only made for camaros up to 85'. Old style heads still.

For a no hassle, reliable, bolt on and go kit - these Martin kits are still excellent. They are very well engineered and they have no lag.

There is some fuel distribution issues because of where the compressed air is introduced to the lower plenum so they like to run fat. There is no puddling issues because its a drawthrough setup and this kit likes large carbs. Make sure your crossover pipe has a flex joint in it for expansion.

The only thing I would upgrade is the compressor on the RayJay turbo to a 60-1 wheel and run water/alcohol injection. Then you would have enough capacity for 600hp. They 301EE turbo tha comes with the kit has the same flow map as a T04B V1/V2 compressor, so its limited to only about 425-450hp. But the torque with the smaller compressor is awesome! I had over 500ft-lbs at the rear wheels at only 9psi without water injection on pump gas.

honestly, you'd have to play with it some for fitment to work. i'd say A/C is a no go, and if you did get it to physically fit, the head coming off the downpipe would make it impossible for the a/c cores to do their job. the crossover pipe into the pass side manifold would have to be a different shape, as that particular pipe WOULD hit the k-member. but it looks like the position of the collector on the manifold itself would allow you to get around that with a fabbed crossover.

as far as your car coming with a qjet and a 350 from the factory, that is incorrect. the 350's weren't available till 86, and were ONLY tpi, and were very limited in numbers. the 350 was not widely used till 87.

Please Please Please, find an 86 w/ a 350 that was sold to the public. They do not exist.

Like I said above...you have to have the camaro kit for it to bolt on and work.

I have the camaro kit on my car and its quite different than that one.

Evil Ed

is anyone selling the camaro kit ?

Marc Brown

Just got my martin turbo kit back from powdercoating.. it's going in a KITT car... Here is how it looks now ......



this is the cover I want to use on it... I photoshopped this... so sorry for the inaccuracy... but this is what I'm going for ... think Knight Rider



anyway.... I personally love it.. I like it because it was from 1982 and, well KITT came out then two... I know he (from the show) used an turbine engine... but the turbo is as close as I can come to that... anyway... I personally can't wait to get this in .... here's the engine bay it's going in.... still in primer though...



thanks, and yes , they will fit... just watch the k-member...I test fitted mine on my 305... 305 was blown... seen better days...anyway.. what I did , which is the easiest for me... was I took the exhaust manifold... had two of... and cut it and welded the flange up about an inch... I also turned the flange so I could get my bolts in ... cleared very nicely then... the easiest would be to get a tubular k-member and upgrade the front a-arms also.... but i don't have a problem with my suspension.. I love mine... anyway... thanks for replying.. I haven't sent anything here in awhile...so sorry so long... but I do love the martin kits... they are just cool , kick @ss lookin....

thanks

I have a 91 RS Camaro and iam going to do a motor swap a V6 For a 400 Small block and throwon top of that the martin turbo system . My question is can anyone tell me What kind of boost i will be looking at with this kit. i also have a 6 speed manual and rear end out of a 97 formula FireBird iam about to throw in to.

RacerRick

I think you will be dissapointed with a Martin Kit if you run a 400 with any kind of decent heads, unless you upgrade the compressor. As I said above, the flow map is identical to a To4B with a V1/V2 compressor and will only flow enough to make around 425-450hp.

I have a 406 sbc that make 430hp with just a set of ported 462 double hump heads. It is a hydralic flat tappet cam motor with 10.2:1 compression that runs on pump gas. So unless you upgrade the turbo, its pretty much too small for a 400.

Zen91camaro

RacerRick

If you are destroking it, and going to be running a turbo, I would just run a 350. Smaller bores are less detonation sensitive, and you do not need to rev a turbo motor because of the torque production.

For an 87 octane engine, you would need to start at around 7:1 compression if you are going to boost it, and run good quench, and an efficent chamber. And you will still not be able to really turn up the boost. I have a basic 350 with a martin setup on it with 7.8:1 compression and run up to 9 psi on 94 octane pump gas. I am adding water injection to see if I can do better, but I am pretty much maxing out the compressor already.

Zen91camaro

I see um well I guess I'll just have to put it together and see what happens but just to ask where can I pick up a 60-1 compressor at for it I would love to try to make 500to600 horse that is my dream . I also have a MSD 6 Btm controler to us with it . And I really don't have all that much money to just go out and buy a bigger turbo . If u could help me out with the compressor and where to get one I would be very greatful. Thanks rick

RacerRick

There is going to be a lot of issues with your setup. You seem to have gone for the biggest of everything, and that is not good. Everything needs to be matched.

Upgrading the RayRay 301EE turbo to a 60-1 compressor is not cheap. Last I checked it was a $600-700 upgrade to the existing turbo after labour. Turbonetics can do it, or if you have a local guy, any good turbo shop can do it.

Also, I would not run a 400 sbc in 600hp application unless you seriously work over he block - and then its still a crap shoot on whether it will live or not. The factory blocks are weak, and anywhere north of about 500hp, they are seriously lacking. You can do a lot of work to them to make them stronger, but the price is pretty much the same as an aftermarket block at that point. The best factory block is a 2 bolt main 509 casting. For a boosted application you should not bore the block more than 30 thou over as the walls are pretty thin to begin with. For boosted engines, I like to run a short fil of block filler, and an external oil cooler.

After you sonic test, magniflux, add splayed steel main caps, deck plugs, a short fill, square deck the block, and bore/hone it with deck plates, and purchase the block - you will be close to the price of an Iron Eagle. They are $2200.

On the other hand, an 010 high nickle casting 350 four bolt main block, is stable to about 650hp and much cheaper to get everything for. You still have to basically blueprint the block, but you don't have to get any of the expensive machine work done.

Either way, you are going to want good flowing heads. Stay away from large intake ports through. You want good port velocity so there is good cylinder filling at low rpm where the turbo has not spun up yet. This will also help reduce lag.

If you want cubes, go to a 383 with a stroker kit. Make sure its a steel crank, and not cast. At this HP level you are going to need it. Aftermarket rods, and forged pistons are also needed, as well as attention to detail when assembling.

If you don't have a lot of money - just build a good 383 or 400. Both will make 500hp NA on 91 octane for less than it will cost to put together a turbo motor. If you want to make some decent power for cheap - take a basically stock low compression 350, and drop the martin setup on it, and it will make 350+hp and 400+ft-lbs are the rear wheels. If your bottom end is strong enough - upgrade the compressor to a 60-1, do a cam swap, add water injection and make close to 500hp. Better heads will get you close to 600hp.

Been sitting here reading all the turbo threads this am and i am having trouble finding any working links to a working web site. What i have is a 79 K5 blazer with a 4bolt gm crate from the wifes old 90 V2500 burb....prior to that i had a normal old crate for a 79 with a moded manifold to run the tbi setup. Just looking to get another 50-75 hp out of her and i am trying to decide which way to go. Anybody have any working links where i can buy the raw pieces to build something and maybe one to have a chip burned to handle it?

anyone have photos of crossover tubes for this system? Also where can i fine the 2" and 3" coupler tubing for the turbo connectors?

Peter Gaw

i have a Martin turbo kit if anyone is interested. It was a vette kit that I had fitted too my chevelle. I modified the one manifold to work. It was on an old 327 ss engine. Running it with throttle body efi really made a difference. I have the "blow off valve" resprung to produce about 10lbs of boost but that can be changed. Water alcohol injection really calmed down the pinging.
Went to multiport efi and twins with an intercooler.

RacerRick

Price? Location?

Peter Gaw

I'm in Canada so I would ship it. It's going on ebay if there are no takers.
I rebuilt the turbo and have about hours on it. Not much to those kits.
I have extra ducting for martin kits that are probably from the truck or camaro kits that I would include. I might have some extra intake parts. I could send pictures. Doesn't look great right now cause the paint burns off these things in minutes.

500 US + shipping.

The biggest improvment on getting these thing to work is efi, period. I have a msd 6 btm (which I still have) that didn't make much difference. You will likely need a higher output fuel pump as I did. Lots of heat protection will also be needed for wires etc.

The intake is tapped for alcohol/water injection which I would recommend highly. Aluminum heads would help pinging issues and be sure to have compression low enough.

I think I have a picture of it installed somewhere.

RacerRick

Where are you in canada? I am in toronto and already have a Martin kit running on my 80 Z (well, its not running now - car is all apart for paint).

I built the motor for the turbo setup and it works excellent. I have no pinging on 91 octane at all with no water injection at 7psi, and it makes about 350rwhp. I am using a 800cfm holley spreadbore double pumper, and a 130gph pump.

What did you use for water injection? I have an Edelbrock Varijection kit.

You can send the pics to RacerRickxx at Hotmail.com.

Peter Gaw

I'm in the center of the universe, Regina, Sk.

I have the cooling mist single stage kit. I could never get the timing curved properly and couldn't get any help locally and just got sick of it. Definitely taking a loss on this stuff but it's just sitting in the garage.

You are a smarter man than I am. I may have spoken to you actually in the past about the kit.

RacerRick

I am interested in the kit, but being tax season, all my money is going to the government!

I am not that smart, I just built the motor for the turbo.

Peter Gaw

my kit will be hitting ebay in the next week or two. Ebay name is red18160. Just gathering the parts and getting some pics together.

JoeyBigBlock

Hey Peter can you send me some pics of your system? sounds intresting

BigBlockTurbo

I have a Martin turbo charger kit for early 80's Smallblock chevy in a F body it was on a running car when I bought it.It has been gathering dust in my tool box for 6 years.Other than being dusty it looks fine.I had allways planned on putting new brgs. and seals in it just because its off and really not that hard. How much would a good one be worth?

RacerRick

Incomplete kits or kits that need repair are usually listed anywhere from $600 to $900 on ebay. I have only seen a few complete kits that were ready to run and they went for more.

BigBlockTurbo

Thanks for the info. The kit I have is in good condition,the turbo has very little end play,no cracks in the manifolds.With new Brgs./seals,some gaskets{not much money} and the right motor some one could be having fun with this. I'm hunting some shipping supplies so I can get it boxed & weighed.I'm going to list it on Ebay,and start it at $500.00 NO RESERVE plus what ever the shipping calculator comes up with.That sounds like a fare price to start with. Thanks again For The info.

hey big block turbo where are you located and will u ship to t.o

BigBlockTurbo

I live in Enterprise Ms. 39330 zip code for shipping purposes.What is your postal code?

BigBlockTurbo

Any one interested my Martin Turbo kit listed on Ebay today.Item # 140320775741

Peter Gaw

Well, I am going to post my kit on ebay and see what happens. Not going to take lowball bids either.

The Kit is in good shape, rebuilt turbo has probably no more than 10 hours on it. I had new stainless steel flaps made for the bottom of the intake. This kit even came with the emissions thingie that I took off but is pictured. Just minor oil line fittings missing. You will need to get some new silicone piping but I may have some in the garage to include with it. Manual as well. I have the "blow off valve" set to give about 10lbs of boost.

The vette manifold was modified to clear the plug placements on the heads I was using (low compression GM truck heads that were ported and three angle valve job etc). Crossover tube is there too.

Should be one of the most complete out there. Also should consult someone like racerrick for all the ins and outs of setup.

Peter Gaw

Better show the turbo too.

Peter Gaw

Why I changed the setup.
Added an intercooler and throttle body efi. Sorry for all the posts.

RacerRick

Thats a nice setup. I wish I had the money - I would buy just to have a second kit in nice shape.

BigBlockTurbo

Well mine did not sell.In the paper or ebay for $500.00 I know that it doesn't matter that I payed twice that for just the kit,with it installed and running,before I removed it and packed it up.So Rather than give it away I've packed it back in my toy/tool box.You never know... might stumble up on another 3rd gen body .. or get week and install it on my old 4 wheel drive..1 ton.

RacerRick

I think I looked at yours on ebay. Is it the one with the plate rivited on the bottom of the upper intake?

If so, that bascially ruins what made these systems so good compared to the others. The reed valves and boost bypass valve has been removed and a plate rivited over the ports. That would make some serious lag, and there would be fuel pooling issues until the motor got up on boost.

Do you stll have the bypass valve and reed valves for the intake? Take the plate off and put them back in. The setup really works well when its all together!

BigBlockTurbo

Yes,you are right. The reeds have been replaced by a alum. plt.Done by the previous owner.The bypass valve is still installed in the intake. I had not even looked at it till you mentioned about the reeds,thats how much I know about this setup.It ran pretty good in the old Impala but it did have a bog when you gouged it but wasn't that bad I just figured it was that Giant carb he had on it.{the main reason I didn't buy the Holley he was running on it when I bought it}Thanks for the Information.I looked back at the paper work on my old 4wheel drive,10.25 to one compression so that idea is gone down the tube.With that and new reeds needing to be built.I will be relisting it starting at $300.00 plus freight Third times a charm I hear.

Peter Gaw

listed it today. Item number 320385652371 on Ebay.

BigBlockTurbo

Wow,again mine didn't sell.I saw just an intake go for $110.00 plus shipping with one missing tube and bent reeds.Oh well third time may not be a charm.Rather than give it away and loose so much money,got a wild Idea...really cool mail box post ! I've made some real neat ones over the years but this will be the most exspencive for sure.If my wife doesn't talk me out of the idea I'll post pic. Ya'll probablly al ready know this link it clears up some of the MARTIN questions about the company.Cool site about just the martin turbo kits. http://www.geocities.com/microjet_2000/FAS/turbo1.html
