Ol' Blue from this site has a single turbo, a T-60, in fact he's going twins and I'm buying his header/exhaust fabs and turbo-ing my forged 355. Yes, you'll need bigger injectors, he's running 24lb/hrs right now. As for pics, I'll try to find one and post it up in a bit.

Yup I'm actually running a T61....it seems to be a perfect matchup for a stock 305tpi....I am running 24lb ford racing injectors @ 43psi fuel pressure....at 7psi with quite a few problems my 305tpi ran 13.6 @ 105....I actually dont have any recent pics of it. just the ghetto rigged pics with a nice dryer hose intake...which is all gone now.....TPI CHIPS burnt me a chip for my boosted 305...it was $150 shipped I do believe....I'll have some numbers for the car @ 15psi this thursday.
If he can wait I may be selling my injectors, turbo, wastegate and the 305 turbo chip within the next couple months....I may be going to a twin setup.

im the guy he asked the question for and i was just wondering is it safe to run a single turbo on a stock 305 tpi? i know they have 9.5:1 compression. also is it a real big deal to build your own and could it be done for around 700bucks?

Lower boost shouldnt be a problem...I've been beating on my 305 pretty hard lol at 7psi it did pretty good....at 15psi reliability dropped a bit but its just little things. $700 is a pretty tight budget....but any thing is possible.....I'd probly want around $500 for my turbo, wastegate, injectors, burnt chip......which is a steal.

Obviously everything is still on my car but I should be taking it off sometime in October...I'll shoot you a PM when I remove it. I'm actually going to try and run at the track tomorrow shooting for 12s on a 305....Then I will be working on a twin setup w/70mm turbos....
