Did anyone else notice the description on these? "14 ga mild steel or 409 stainless steel mandrel-bent primary tubes" I guess that means what ever they felt like using that day. lol

StngKlr,
I was going to put the PCM inside too untill my buddy said "Why not move the batt to the trunk and but the PCM in its place." Every so often we have a good idea.

Are you going to make the harness or are you going to buy one? I still have not made up my mind.

 

Thats not a bad idea, but I'm gonna put it under the dash so it will be hidden. I think the engine bay will look tons better. Also, I'll be making the harness myself. I have all of the pinouts I think I'll need, so I will let you guys know how it goes.

 

They are a waste of money. 01-02 Factory manifolds flow better than shorties. You can even have extrude honed to get more flow.

 

So where can we get long tubes?

StngKlr,
Sorry to keep clutering up your post but I am learning alot from this.

 

They are not available yet. You will have to get them custom made.

 

Hey StngKlr,

If this picture doesn't give you motivation to hurry up and get that thing in there......well i don't know what will...........

Welcome to the LS1 club....:hail: :hail:

 

Didnt you just spend 10k to join?

 

Yep he bought his way in. Not to say that it is bad but for 10k I will have a LS1/T-56 swap with headers, MTI stage 2e heads, MTI X1 cam, full rear suspention, ram air hood with box, ZR1 wheels and tires. The only thing missing is the 4.10s out back. I will have to wait untill next year.
Oh don't forget the tuning on a dyno.

He did get it done a whole lot faster than I will.

If anyone watching wants an idea of how much things cost here is my list. Some parts are missing Ex. gaskets, push rods ect. but it will give you an idea of how a project gets out of hand fast and I am sure a few things will change before it is alll done.

LS1/T-56- $4400 (with LS1 harness, PCM and engine mounts) 11k
MTI stage 2e heads- $1795
MTI X1 came- $400
Rear suspention- $350
Speatech stand-alone harness- $750
JBA Headers- $650 (Not sure if I am going to get them)
Ram air hood with filter box- $700
Center Force clutch- $400 (??)
Fule regulator- ??
Fuel pump- ??
Tuning- ??
ZR1 wheels- ??

 

Yup, I did buy my way in......

Everyone will buy their way in.......unless of course you can build an LS1 engine from scratch......

 

Believe me, your car has been motivating me since day one. I wanna have this thing running so bad I can taste it, but I dont want to rush things too much. I gonna check and double check everything before I even think about touching the key. Too much invested so far to have it go down the tubes.

Yours looks killer with it all cleaned up. So are you driving it yet?

Heres my project sheet so far:
- 89 RS - $1000
- LS1, 4L60E, PCM, Harness, All Acc. - $3000
- Motor Mounts, Tranny Crossmember & Mount - $250
- Fuel Pump (92 5.7, I know) - $70
- Vette Reg./Filter - $50
- TR224 Cam, Springs, Pushrods, Gaskets - $800
- All Fluids & Filters - $100
- Engine bay paint, primer etc. - $175

Still need:
- Radiator - ?
- PS lines, Fuel lines - ?
- Hoses - ?
- Interior - ?
- Various wiring and connectors - ?
- New head lights - $100
- New tranny lines - Trade

I know theres other Nickle & Dime things to get, so we'll see. I dont even want to add it all up.

 

So you did end up going with the TR224 cam like I recommended? Did you get the 112 or the 114? That is gonna be one bad *** setup either way.

 

Yeah thanx for the advice. I called them up and they were super nice and their whole operation looks top notch so I went with them. Even the way they packaged everything up was above par, unlike the people that I got the motor mounts from. Tranny crossmember was poking out of the box. Oh well, they werent broken or anything so... Yeah I went with the 112 cam. I should feel a good bit of extra power with the cam. I'm gonna drive the car with the stock one in first, then when I get it tuned, I'm gonna have them put the cam in over at AMS.

 

yeap, thunder racing is the best place to deal with! Great customer service and awesome products! When I bought my dampner from them it was missing the ac pulley. They didn't even second guess me and sent the thing right out. Thunder racing is the first place I go for parts.

Oh and if you want a good place to have the pcm tuned call dyno pro performance

 

Looking good! Check out my car if you haven't yet. It's CA smog legal too. Been running a year now!

Link to my site

 

Look what I found. They don't look like LT headers because they seem to be missing the bottem part in the pic. They are the best looking set I have found yet for the swap.

HEADERS

 

$700, yikes! And they look like 1 5/8 primarys also. And I wonder if thats with some sort of coating or not. I dunno, thats alot of cheese for a minimal gain. I could have a 100 shot dry kit installed for that. I think I'll wait on headers for a while. Thanx for the info though.

 

I didn't get those $700 headers for my swap either.......was told they are mainly a show piece and don't really add much HP, in fact they once tested it on a Z06 vette and actually lost 2 HP

 

Well I bit the bullet and ordered the rest of the parts I need for the swap. Next I will need to order the MTI 2e heads and a TSP 331/337 cam. :rockon: Then if I am still not happy that cam loves NOS so I will be set to realy break things. hehehe Boy am I going to have fun this summer.

Good luck with your cars guys!!

Oh and lets get some dyno numbers and 1/4 mile times.

 

Any updates "StngKlr", dont leave us in the dark man. Oh and also how much did you get your engine combo for $? I found a shop close from home. The guy is a professional mechanic and he says he could probably do the swap with the rite tools and knowledge. Im going to order my motor mounts and tranny crossmember probably in a month or so then start looking for a LS-1 / Auto combo? Keep us posted "StngKlr", really interested in the outcome.

:hail:

 

Already posted above

 

Sorry for the delays guys, but I've been set back a little with problems from the steering column or ignition lock. I think I might have to get a new ignition lock and key, dunno yet.

https://www.thirdgen.org/techbb2/sho...hreadid=233528

I have made some progress however. I hooked up one side of the power steering. I'm still searching for the high pressure line as the one on the LS1 was just cut off. I'm gonna try to use one of the old ones first, but I dont know how thats gonna turn out. I'll let you guys know.

Started tracing old wires and splicing with the LS1 wires, almost have it done. Also, I was looking at the harness for the LS1, and it looks like that most of the wires are long enough to put the PCM inside of the car. You would just have to route them through the firewall where the old HVAC wires used to run through, and splice maybe 6 wires total. I wont know for sure untill the car is up and running first. The PCM will stay in the engine bay till then.

I got my tranny lines yesterday. I'll put them in tonight and then bolt the tranny crossmember up along with the torque arm and driveshaft.

Still need to hook the fuel system up, and do something about the rearend.

More pics. of everything tonight, or if its too late, then in the morning.

 

StngKlr,
Can you give me some input in the harness wiring. I have most of the wiring diagrams but I am not sure were the best place is to tap into the factory thirdgen harness. Any tips would be great!!

 

Bunch of pics., I hope the mods dont mind.

Heres the P/S lines. I hope thats how you hook it up.

 

Tranny lines. So much eaiser to hook up and they look stock. Traded a Holley 600 for them. A guy I know at a dealership got them for me. Brand new for a 99Z28.

 

Some wiring. You can see I'm using the old injector wires with a 15A fuse instead of 10A in the fuse block. Then the blue and green I'll use for 12V switched and 12V all the time. I'm also leaving the old harness in for now, in case I need some more wires somewhere.

 

Thats the hole I'm thinking of using for the PCM wires to go through into the car. But thats down the road. (Not the gigantic hole, the one to the right.)

 

More wiring. Floor board is hosed.

 

And some more wiring.

Thats all for now, dont want to clog everything up.

Also, I found out I definatley need a new ignition lock and key. Yet another set back. And if thats not good enough, I found out that my torque arm mount will not work on the 4L60E. I dont know if the V6's are different, but I'll look at the 86 and see for sure. Otherwise its off to the J-Yard to find a 4th gen mount.

 

You can see from this thread https://www.thirdgen.org/techbb2/sho...hreadid=233528
that I'm having a good time with the wiring on this car. I'm still not done 100% on the wiring, so give me a few days to get done and then write everything down. I'll help as much as I can, or if you have specific questions I can probably answer those better.

Good luck with your swap.

 

I took a different approach on mine...built a conversion harness that connects to C100,C101,C105,starter on the LS1 engine harnerss, and C100 and C207 on the 3rd gen chassis side. No cutting of my TPI harness required.

One trip to the junkyard, snagged relay connectors, a 3rd gen C100 and C207 connector. Grabbed an LS1 chassis harness on eBay for $40, had all the LS1 connectors and plenty of Packard wire.

Pics of the fabbed harness in progress are here:

http://www.warpten.com/carpics/ls1/DSC00036.JPG

 

Now that is a great idea. Some one should make and sell a conversion so you can just plug these two harnesses together. I know it is a little more in depth than that but you get the idea. I am sure you would make some $$ if the price wasn't $750.

 

Thanks for the compliment, but it's not commercially viable as a product. Too much variation in connector pinouts across the '82-92 F-body line. Some have the oil pressure gauge feed on C100, others on C207, my '82 had 12VDC from the batt on C100/G4, the '88 harness I used long ago had it on C100/G5, etc...

And then there's all the potential variations on the LS1 side.

You'd go nuts trying to mass-produce all the combinations, and doing each one custom would put the price out of reach.

 

StngKlr,
How is the project going? I got everything on the Iroc disconnected and I am going to be pulling the engine soon. I was looking at the harness and I am a little bumbed about a few wires that are in the main TPI harness. It seems like the fog lights are mixed in along with the fans. The good news is I see that the bulkhead connection comes apart into two harnesses so the heads lights and wipers should function with out a problem. Now I just need to sit down and figure out what wires I need to splice into on the engine harness side of the bulkhead connector.(Drivers side)
My main problem is that I sold the TPI engine along with the harness so I need to pull out the whole harness. I will need to pick up a bulkhead connector so I can splice wires and I will also need to pick up the the dash connectors, that are in the ecu end, on the engine harness so I can cleanly splice in the gauges.

Would anyone know if other car use the same connectors (Ex. Blazer) because I will never find a camaro around here.

 

I'm kinda idle at the moment, just waiting on some parts to come in and I've happened upon another car that I stole for $150. Turns out the ignition key/lock was bad on the 89, so I had to replace that. Not a big deal right. The steering wheel puller I bought was a huge piece of crap, and I ended up having to cut the wheel to bits and actually used my coil spring compressor to pull the wheel off. About 5hrs and a sore backs worth of BS. But its all done now, and just need to add a steering wheel to the list.

Sounds like you are on the right track with your wiring. I'm not too sure about different bulkhead connectors working for different cars, maybe someone else does. But if no Camaros are in your reach, then you might try EBAY. You dont have to use any of the old TPI wires, you can mate the LS1 harness with wires from the Bulkhead. I just used the old injector wires for injector power on mine because everything is already in line, you just have to put 15A fuses in instead of the 10A fuses in the injector slots in the fuse box. Those are the only wires I used, and you could just run new wires to that spot where the injector wires tie in under the dash where the old ECM was.

Best thing to do is expose all of the wiring under the hood and just sift through the wires till they are all seperated. You shouldnt have to cut anything, and all of the wires going through the passenger side fender will be gone when you are done. Also, I think only one dark green wire goes to the ECM from the fan relay. Leave some length of wire off of the relay so you can connect the LS1's fan wire(s) back to it. Also, the fog lights may be wraped with some TPI wiring, but should be seperate from it.

 

Cool stuff!

If I had waited just a few months longer the LS1 knowledge base would of been available for me to do this swap instead of my LT1, as it is to compete now a custom cam and heads are going on.. maybe the next project will get an LS1..

Keep the info coming, this post is already on my favorite list, GOOD JOB!!

 

Hey guys, I'm getting ever so close to getting this thing running. Just got a new radiator for a 92 5.7L. The vats bypass box is on its way. High pressure P/S line is on its way. Torque are mount for the 4L60E is on its way.

Need to reinstall the fuel tank, but the rest is hooked up, just keep putting it off because I know it will be a PITA to put back in.

Also, I decided to leave the PCM in the engine bay. Benn toying around with some bracket ideas, but still undecided. The hole that I was thinking of would probably work, but the plastic box for the heater core is right in the way. It would take some modifying on the box to do, but I'm just not up for it right now.

What else,........... heres some pics.

What do you guys think of the Red Power cables? I'm thinkin I need to wrap them up with some flex tubing, they stand out too much I think.

 

Is the fuel line too cheesy? I'll upgrade down the road.

 

fuel line is fine, but the orange has got to go

 

Yoe can see the Power lines here, and a new rad.

 

And... I was going to have this remote solinoid functional, but decided to use it as a junction for now, and all the fuse links just turn out of the C100 connector to the lug. (Yes there is fuse links on the wires.)

 

Looking good man!! I would flex tube the power wires for looks and protection. Than I would double climp the fuel line you have setup because of the pressure it will be seeing. You wouldn't want fuel to hit the hot exhaust or you may need to start your project over again.

 

I'll be watching the connection real close at first. Hey but it is "Fuel Injection" hose so... I have another splice like that down by the regulator/filter also. I will be watching closely.

Got the P/S line today. Kind of a biotch to put in, but not really that bad. Just had to bend it a little for it to clear the pulley.

Pics.

 

Another.

This weekend will be dedicated to putting the fuel tank back in, getting radiator hoses, and battery. Hopefully the VATS box comes in so we can start her up.

 

looks good, is that a custom h/p line or does it have a part number.. looks like it would work well as a replacement with my vette accessories on the LT1.. right now I have a caprice line wrapped under the car..

 

Its just a line off of a 99Z. Worked out pretty good.

 

cool thx..

 

Well I have some bad news. My LS1 is MIA! So I called to see where it was and the guy just shipped it out yesterday. The thing should have been shipped early last week!! This has added a week to my build. The good news is that I just ordered my new performance heads, cam, push rods and lifters. I still need to order shims and head studs. My conversion parts are being held up because of the fuel system parts but I can under stand that but I can't under stand the engine not getting shipped.

 

Well she got a new set of eyeballs today. I learned its much eaiser to put the lights back in with the nose off. Them stupid springs were giving me some trouble.

Also got the Vats bypass box today, need to wire it in tomorrow, and the main thing is to get the fuel tank back in.

Pics.

 

Half way back together.

 

Looking good bro! Cant wait to know how it runs, performse ,& kick ***.
