.... yet another turbo charged Camaro build, but this time it's mine!

Okay, what we have here is a 400-SBC, w/72cc heads (not ported, yet), yielding a 8:5.1 compression ratio. Not decided yet if I'm going to keep it carbureted but with a blow-thru design, or go EFI, as right now I'm just getting the preparation finished. As you can see from the pics, I spent days making sure the sides of the engine were adequate. I literally soldered extra wire on top of the original harness, and routed everthing completely out of the way. The spark plug wires are nicely tucked against the valve covers, and were cut properly to fit the exact length to the distributor cap....

On the passenger side, you will see that the only obstruction now is the steel fuel line(s), the bracket, and the coolant resevoir. By next week, the resevoir will be relocated, that little bracket will be tossed, and the fuel lines will be re-routed completely out of the way (scrapping the mechanical fuel pump, and I'm running my fuel lines up against the firewall, entering from the back of the intake manifold). Please excuse the mess, as believe it or not that is DUST that you see in the pics. I'm painting the engine bay anyways when all is said and done, but for now everything is just getting mocked up....

I'm not screwing around anymore in terms of header quality, as I I'm looking for a set that is really strong, and I could care less how much they are. I have absolutely no time to weld some on my own, so that's not an option for me. Now, there is no need for me to go twin turbo, as a single T67 w/400 cubic inches will place me in the 9's with no problem (although I'm only really shooting for a streetable ten second ride). The weight of the vehicle will be somewhere around 3000-3100 lbs when all is said and finished, so that will assist with a few tenths here and there....

BBS, what would you recommend. As you can see, I'm running a V-Belt setup, I scrapped the A/C, scrapped the smog pump, scrapped the bracket right above the power steering pump, so there is plenty of room. Intercooler will be mounted once I get it, but I'm not even at that point yet, as I'd like to get my A/C delete box painted and installed, along with the fuel lines finished up, first. Again, still unsure about keeping the carb, or going EFI. I had an HSR, but I sold it though. If I can get my hands on another one, or possibly an LT1 intake conversion, I might go EFI (I don't like the look of the TPI, so that's not an option lol)....

 

Now, what I would like to do, is, have a much stronger set built in comparison to these from SSAutochrome. I'm kind of leaning away from the under the engine method, I'd rather have them meet up in the front similar to Dave's 3.1 turbo setup. Of course, not as high as Dave's coming from the passenger side, it's gotta remain under the upper radiator hose....

 

Why are you avoiding the under engine method? Once is installed is easier to work around the engine, specially if its hot.

I would keep the V belt since is much more compact.

 

^ I honestly liked the look of your old quad setup. This Camaro is going to be shown as well, and that is definitely the look that I'm after, and am seriously contemplating. The mechanical water pump will be tossed, making way for an electric one, so that should provide a little more room for the crossover. Worst case scenario, I would need the standard single turbo header, but with the crossover feed welded by the front, allowing the crossover to meet....

Oh definitely, I just sold a serpentine setup....

 

Decided I'm going EFI, as the carburetor can easily be done, but I can't chance risking detonation, so I'll need the tune to be very precise. Anesthes over on the alternative intake boards has turned me on to the Victor Jr. intake, albeit w/injector bungs, and 90 degree elbow w/larger throttle body. Seems like the best route to go, as the single plane will be better than the Edelbrock RPM Performer's dual plane that is currently on the engine now, not to mention the RPM Performer's lack of injector bung's (it's a non air gap). The pic below is an older Victor Jr, as the newer one's are injector bung ready....

 

I know they made a BBC victor jr with bungs. You have the part number for the SBC version? I haven't seen it yet. I had the same thoughts in mind for a SCB victor jr I have kicking around. I picked up a 65mm throttle body for it. Ryan.hess here at TGO was seeing them cheap (new take-offs). Maybe he still has some. Firstfirebird was modifying one. The single 65mm equates to a 53mm TPI dual bore unit.
----------
The LT1 intake seems to work quite well also. You can pick them up for about $100. I think you can buy just the distributor bung and block off plates from lt1intake.com

Not saying it is the way to go, but I converted one and run it on an old school SBC and it seems to work well. It is a cheap intake for the HP it gives.

 

It's funny, I called Summit Racing's tech a few days ago and asked them that same question. Told them that from the pics, only the BBC & Ford Victor Jr's. were injector bung ready. Tech assured me that the newer ones have them, but I didn't ask for the part number. I have to order one any way, so this Monday I'll give them a call and nab it for ya....

I really wanted to go with the LT1 intake conversion, but the guy that bought the business from John Millican is MIA. I may just get another HSR if the Victor Jr. doesn't work out, either way this carb is getting tossed. While I'm still waiting on a turbo header selection, I needed to get the car back on the road. I had a set of Edelbrock headers lying around, they just need a good cleaning to look presentable. Today I cut off the AIR fittings, as they were in the way of my plug wires (that's a lie, I couldn't stand the sight of them lol)....;

Pretty easy process, even w/out a welder (I sold it, don't ask lol)....

u shoudl be able to build a front located crossover that sits at the ex port level with a vbelt setup

 

^ It looks that way from the pics I posted, but the mechanical waterpump will have to be tossed to get the crossover to run evenly across. The v-belt waterpump pulley is very close to the radiator, but the electric waterpump will help by eliminating the pulley altogether....

 

dont bother, out the front turn down past the ps pump, go under the crank pulley and back up the other side. or low mount the alt run the elctrick pump and run a pair of logs with twins.or do u still have the turbo i think u do ?

 

^ Still have it, almost sold it, but glad I kept it. The waterpump is as good as purchased, it's really no biggie. Right now my biggest three concerns is dropping the fuel tank and rerouting the fuel lines, the ECU, and the headers themselves. Everything else is going pretty smooth....

 

i have an moroso elc water pump take it, u do know u need to low mount the alt with the elc pump right.dude u should pbring the car+turbo to the shop this week we can get u a full hotside welded and plumbed before friday

 

Yeah, everything has been gone over regarding the electric waterpump, should come out and look very sweet when it's all done. Although I slapped on a set of temporary headers for the street, I might not be able to drive it just yet anyways as I'm probably going to pull the intake w/carb off tomorrow, sick of looking at it lol....

 

Just spoke to one of the tech reps that I know over at Summit Racing. He was positive that he seen them, but after checking stock for me, he said there was nothing there currently being offered. Strange! They still have them for BBC's and Fords w/the bungs, but none for SBC's. I'm pretty shocked lol. Looks like I'm either buying another HSR, or installing bungs on the Performer RPM that's already on the engine. I'm definitely not going to buy a Victor Jr. and start cutting into it, unless I find a pretty decent used one....

Carb is still on, gonna keep it on until I have everthing ready for the fuel injection swap. If you wanna take a ride to the track this Friday, I'll be taking it down as is. Still need the intank assembly, but I already have the Walbro pump. Wanna run new fuel line too. I have the flare gun, but I really don't wanna mess with 22 year old fuel lines....

 

not sure about the track this weekend man, ive been preping my car for high boost, ive been testing at 16-21 psi and im heading for 28 psi.gota get the car ready for the f-body nationals comming up in 2 weeks

that leaves me this weekend and part fo next week to finish the car
and i gota runa full 3 inch catback, swap the drag springs back in,drop in the strange s60 rear and build my new 3 inch dom driveshaft.

and u think the car pulled hard at 7 psi this things a whole new animal hehehehe

 

^ ...... BRING IT!

 

im not bringing a dam thing till im sure all the bugs are out of it this time.
i am loving this new turbo though HUGE TURBO'S FTW!!!!!!!!!!!!!!!!!!

 

Well if you are interested in the Quad setup or even the single that I currently have... well that is a coincidence, both kits are currently for sale in ebay and they both end in 3 hours!

 

When you say injector bungs, you mean little nubs on the intake that would have to be drilled out right? Not actual threaded stuff.... Cuz my RPM Air-gap has those little nubs.

If so, have you considered these? http://www.midwestmotorsportsinc.com.../MWM/52031.jpg

Or these:

http://www.holley.com/9901-107.asp

 

....

What size....?

 

thats exactly what he needs,the manifoldsdont come with bungs u actually have to stick the manifold ina drill press or milling machine and drill the holes for the injectors.
----------
72mm

 

Injector bung ready....

Yeah, the air gaps have them, but the standard RPM Performer's don't unfortunately. I'm liking that Holley intake the more that I look at it! Thanks for posting that....

 

tht intake is nice even has a place to bolt the fuel rails down to,rob read my reply above

 

72mm??? When did you get it....?

 

ebay unit, wa ssupposed to spec as a 70mm but when i measured it with a caliper it came out to 72mm

 

Already installed, and tuned for? No wonder you've been so quiet lately....

 

lol yup ive been busy, now i just gota make the hood close,im waiting for one of our shop friends to come buy and fiberglass the hood for me, i need a 1.5 inch buldge put into the hood i have for it to clear the compressor housing,
though i might be able to get my hands ona smaller compresor housing this one has a 5 inch inlet with antisurge.if all else fails i can install the t67r (to4z) i have as well that fits under the hood with ease

 

Sounds like a TV series turbo. What size is the exhaust wheel exducer (the part where the downpipe connects up to it)? What is the exhaust flange (T4, T6) and turbine A/R.

That thing has to crank at your test pressure of about 20 PSI. 28 PSI will really be a handful. What ET are you shooting for in the end?

 

compressor
74mm inducer
100mm exducer
turbine t4 flanged
80mm
1.05 ar
heh i put the slicks on it and even with the spool in the rear and some 26x9 slicks d05 compound this thing is all over the place.dropping from 4:10's to 3:42's i hope will tame it down some but it may actually make it more wild ill soon know. 3rd and 4th gear burnouts anyone?? lmao

i know ur gonna ask so yeah this thing does not spool till high mid range 2nd gear i get about 9 psi out of it at redline in 1st gear and full boost by about 5,500 in 2nd.
but i haven't tried coming up on the conveter and using the antilag system yet im actually scared to try it lol

built the car to run in superstreet its a 10.90 index class

one of the 10.5 tire classes might look like fun as well depnding on hopw fast we cn get this thing to go

sorry for the hijack rob

 

^ Hijack? I'm not like that bro, you know that, this thread is open to all. I was just going to comment though that it's a shame they don't make a transbrake for your tranny....

It's a good thing that carbon fiber gauge set didn't sell yet in my sig, I'm actually shocked that it didn't, to tell you the truth. Gauges were $140.00 new, pod was $30.00 new, and shipping in the U.S. is easily $15.00. That's almost a one hundred dollar savings, cuz I was selling it shipped. Only to find out that now I need them....

On a side note, going to get my hands on a wideband later on, as well as decide which ECU I'm going with. The Edelbrock headers were installed for the time being, and I'm thinking about running that new 3.1 O2 sensor that I had lying around, just to get the gauges up and functioning w/the carb for now....

 

heh who said i was ke3ping the 700r4,i bought an trans adapter i can now bolt in any chevy v8 turbo 350/400 hell even a power glide or t56 if i wanted to.but since im broke ill have to settle for the brand new th350 i have thats been laying around the shop for 4 years.just gota save up for the transbrake.

ur prolly going to need a heated o2 sensor butit wont hurt to try the one u have. go get urself a plx wideband 250$ for the whole setup i beilve.

 

Sounds more like a custom unit more than an OEM unit. In other words, it cost some bucks. Or it could be BW unit. I am guessing custom because of the T4 flange with that size compressor.

I think you are going to need the 3.42s in terms of the MPH vs. RPM you will be turning at the end of the track anyway. Something along the lines of 3.23 - 3.08 might be in order.

I figured the spool time would be about that. Since it is a race setup quick spool doesn't matter. That thing is going to launch hard if you antilag spool it. I hope you have the trans & rear to handle it. The fun part is having something slow spool like that and then hit. It is a lot like a huge nitrous hit.

10.90 index? You have enough engine & airflow for low-high 9s depending on traction.

Sorry for the hijack also.

 

^ Well, a tranny with the correct spline count, of course....

I'll look into that 02 sensor, although a buddy has an LC1 that I'm honestly interested in....

 

yeah its not an oem type unit, i only paid 253$'s for it,i have a strange s-60 rear going in so my last weak link is gonna be the trans, and im putting a 3 inch dom driveshaft in with the s-60

im trying to do research on some air to water intercoolers, i may install one instead of using air to air intercooler like i currently have. the only think i dont like about that is i would have to install the cooler were the front passenger seat is and run 3-4 inch charge pipes threw the firewall.and i never intended this to be a strip queen once its all done

 

No prob. I was suprised to see you were looking up carbed intakes for an EFI application, and also didnt try any other brands except Edelbrock. Holley has other cool fuel delivery stuff too, you should check it out, might help.

Also, it wasnt obvious in my first post, but that first manifold I pictured is a Hurricane intake. Its kind of a knock off of Edelbrock. I dont know how good they are, cuz i havent heard anything good, or anything bad for that matter.... How wrong could you get a hunk of aluminum though that is never gonna be a moving part?

 

No hijack, don't worry. In fact, Dave's just as much part of thread now more than ever, cuz he'll be the first car I'll be waxing out on the dragstrip (and no, not the Mother's type of waxing)....

 

If you don't mind soldering you could take a look at this kit:

http://www.14point7.com/JAW/JAW.htm

I have been running one since last Fall and it has worked well. The sensor was about $50, the connector was about $15, and the JAW controller was around $55. I don't know the exact accuracy of it, but it compares well with the DIY WBO2 with an NTK sensor that I have been using since 2004.

 

megasquirt also has a wideband controler
http://www.megamanual.com/PWC/index.htm

 

^ Yup, there it is, couldn't have a turbo thread w/out Dave mentioning "MegaSquirt" sooner or later lmao. Although I will admit, it's a very good control unit....

 

That is a score and a half. I would like to see that car run. Any chance you will have some video later on?

Yeah, it seems like once people go with a W2A cooler it goes in the pass. seat and the car becomes a race car and no longer is driven on the street. Even with the A2A cooler it should still be in the 9s as long as you don't have to idle around heat soaking the IC.

 

I have been following that unit for years. At this point, I really don't think it will ever be released. It is one of the most advanced WBO2 controllers for the day it was designed (about 3-4 years ago) and is still the most advanced compared to what is available right now.

The noise canceling using a Kalman filter is a great way to get accurate WBO2 readings. What that means is the thing would be accurate as can be and self adjust.

 

well it could be driven with the cooler in that location but wont be able to carry passengers lol.u know video will be up shortly it never takes me long to post up new videos.ill take some once i get the ds and rear in so i can really lay into it.problem is i gota find someplace to take the car to shoot some video and wont get introuble.

ive been testing so much out on the side streets by my shop that they painted "speed limit 25mph" on the roads themselves and my parking lot just isnt big enough

i think i hear that the unit is supposed to be out very soon

 

Yeah, I'm pretty familiar w/Holley, I just never seen that particular intake from their lineup before, and I'm glad you pointed it out.....

It's what's going on internally that makes the real difference, which is why I initially wanted to go Victor Jr. as it's a proven intake manifold. It might actually cost me less if I were to go with the Holley Stealth Ram though, as I already have a throttle body for it, and just found out that I can get fuel rails and injectors for it for very cheap through a good friend, so I'm more than likely going to go that route....

 

that dont mean anything weve got 4thgen v6 guys using slightly smaller/slightly larger turbos and there just breaking 11's, though im sure the boost levels there using have something to do with it, i think those guys are all hanging aroun 14-18 psi if im not mistaken

 

Yeah, but don't forget who's driving, there's the one second difference right there....

 

lmao she wont drive the car anymore,she wont even get in it to drive it around the block shes scared of it now. i think that first shot of turbo lag scared the **** out of her,she leaned into it in 3rdgear and the turbo wound up and she went sideways.tell ya one thing the power is liek a god dam on/off switch.sorta liek junk was saying a huge nitrous hit

 

^ Who's driving it for the F-Body Nationals then.....?

 

me of course

 

^ Umm, err, am I missing something here lol, HOW.....?

 

f-body nats are at island dragway. i can drive at any track but e-town,and thats only cause of that issue i have at e-town
