Default 68 Camaro Turbo Build....Comments/Suggestion

Okay just wanted to start a Build post. As well will love to see any comments. Some will say it want last, possibly it will last, want make power, will make power..etc.. I'm not a Turbo guy, know nothing about it, except I like the power, and how it feels. Now with that said.

My current set-up. 68 Camaro RS, 373 gears, 200r4 (built to handle 1100hp, with trans brake, and 3500 stall). Engine SBC 383 10-8 compression, Block was purchased New when I built the engine (just a standard 4 Bolt block..(pretty sure I don't have Billet caps) 6" H beam rods, Scat Crank, Mahlie Forged Flat Top Pistons, Dart 215 heads, Cam is a custom ground Erson (if you need any specs I will post what I have), MLS head gasket/ Intake Edelbrock Victor Jr Polished, All ARP bolts top to bottom, EFI is the Fast 2.0 / Tank is the Stealth Tank / 3" SS Exhaust. Power is 400rwhp NA, and 600RWHP on Nitrous.

Plan: I wanted to go Turbo. I want to be 600 plus to the Tires. The Shop that is going to build this turbo set up said we leave the engine as is and they are going to build the Turbo set up.

I want it all Polished to look good as well.

Here is what the list is they will do.

Turbo BorgWarner S400SX3-76

Meth Injection Kit

Intercooler: 900HP Garrett High Density Intercooler Core w/ATP cast End Tanks (ATP-INT-00

Bow Off Valve 11 PS: Q.11

Tial 60mm Wastegate V60

All custom made piping/headers

So I'm sure there are going to be comments...I'm good with that since I don't know anything about building a Turbo set-up.

My Concerns was the obvious. I don't want to grenade my engine, was told we will be fine. Also the boost level will be kept at a minimum.

I will invite the builder to the thread to see if he wants to add anything. As well I will post before/during and after pics of the build, and numbers.

I'm really excited to see the build, especially in this vehicle, but don't want to waste 11k on a build if I destroy what I already have. The guy who is building the set up does awesome fabrication, and really can't wait to see how nice and tight this is going to look.


Not sure how to add Pictures......

Good looking car!
Honestly I would sell off that sbc & buy one of the 376" ls crate engines, open ring gaps, swap for a cam spec'd by lil john and hang twin Precision 62's.
Car is a great looker and that LS/twins combo will out perform, out live & add way more value than a gen1/single turbo setup.

Well, compression is a little high for boost. Ideally, you would want to be in the 9:1 to 9:5:1 range for the street. You can make it work of course with the meth/tuning/reasonable boost levels.

Your shortblock will handle the 600 rather easily.

Im sure the cam you have is probably on the smaller side, and a "turbo" cam is over rated.

Don't get me wrong, there ARE differences (especially in valve overlap) when selecting cams for NA/SC/Turbo.
All Im saying is, for the power levels you are shooting for, don't get too caught up in getting a custom ground cam.

My guess is also that you have a flat tappet cam.
Ive never been a fan of flat tappets, but converting over to a roller won't be cheap (but, neither is converting to FI and a turbo).

Converting over to a roller will set you back $1000. Cam, lifters, pushrods, springs, etc...

Pretty much comes down to $$$$$$

Its actually a Solid Roller cam in it now, as well as FI, so hopefully that helps out some.

If you want to optimize your power output with the least boost possible them make sure your components are correct & not just adequate.
You have a very nice car, no reason to not keep the quality up.

Yeah I'm trying to keep the right components put together. I explained that I wanted good only good stuff for the Turbo build, and also want to keep it all polished to keep with what I have. My only concern was adding to my current engine and it staying together. I will upgrade the block later on with lower compression so I can make more power if this one does not hold.

Your stuff will work fine for your goals.
If it were mine though I would do twin Precision 62's with the v-band exhaust housing. It will look better, be better resale & package easier.

Not to sure what your talking about when you say v-band, but I know the builder mentioned about doing v-band and has ordered them already. I have the complete list besides what I listed at the beginning that has been purchased for the build. He is making the headers/exhaust all custom. Then we will have all the hot side Jet Hot coated.

Instead of the traditional 4 bolt t-4 flange that is on yout hot side it is a v-band. Way cleaner & better packaging product.

Sounds like you are already into your build. Hopefully your builder has many turbo cars under his belt and good luck.
