I posted this on a s10 forum and didnt get much responce. They sent me over here so here it goes-

I bought a 67 opel kadett with a 4.3 out of a ty. He took off the turbo- bumped the compression to 11.5 to1 and put vortec heads on it. Got rid of all the injection and carbed it with an hei. It makes decent power now but i hate nitrous cause you always have to fill it and its not around all the time. I purchased a twin turbo set-up off a guy in sacramento and I wanna get the combe together before i tear this thing down and know what im getting myself into.

I wanna stick to the blow through carb set-up and keep it as budget as possible- But i dont want to scatter the motor. I dont mind spending the money where i need to. I was told the motor that the turbo set-up came off of made 720 to the flywheel. Dont know anything about the heads or the bottom end of that motor so that is why im here.

What kind of bottom end do i need? the guys on the other firum were saying run a stock cryoed crank? I have a feeling thats not enough. Are there any shops in the northern california area that have made big power with a 4.3? Thanks

Heres some shots of the opel and the the turbo set-up

Re: combo needed

correct me if i'm wrong but with the wastgate don't you have to connect them to the intake vacum not to one another? i love that pic. is that your set up now? vortec heads flow real good #'s. that's why the guy put them on instead of the stock. was that set up made for the v6 or v8? is there a part # for that kit? i would like to get a set up like that for my mazda truck.

Re: combo needed

right now its just a nitrous car- Makes 260 to the tire on motor and 420 on jug. Compression is way up there but it runs on pump gas. Ive burned down a bunch of big block cars and lost to a few as well. My goal with the twins is to make more horsepower than this car can put to the ground. Im thinkin 750-800 otta do it :D

When i went to go look at the kit it was listed as a banks kit. All it uses from banks is the carb hat- Everything else appears to be custom. Its kinda styled after a banks set up but i called banks and they claim they never used rayjay 300's for a kit. Anyway ive got some leads on a better bottom end- Ill keep you guys updated as i go
