Guest Anonymous Posted May 15, 2001 Share Posted May 15, 2001 hey guys, i was wondering if instead of buying a new L28T motor, i could just convert my 76 280z L28 to turbo. I know a guy that was going to convert his N/A to turbo, but he decided to go small block instead The parts he is selling consist of intake and exhaust manifolds, turbo, fuel rail, mass air flow sensor, ECU (w/ drop down resistor), Engine bay wiring harness, injectors etc. Would this be the way to go??? Or should i wait for a cheap complete turbo engine to come up? Also, my engine has 180k miles on it, is it safe to run a turbo on a high mielage motor like mine? Thanks alot.

jeromio Posted May 15, 2001 Share Posted May 15, 2001 The L28 turbo has different pistons and a freer flowing head. It's compression is much lower - 7.4 or around there. You could run a turbo on a higher compression, NA motor, at low boost. But don't - it'd be alot of work to install and then more work to fool the ECU into giving more fuel and less timing and in the end it'd probably break. L28Ts can be found in most areas for between $400 and $600 complete. Quote Link to comment Share on other sites More sharing options...

In addition, you'll wind up with a block that has the reinforcing webbing cast in and the correct pistons, head, injectors,etc. that you will need. I just recently bought a complete '83 ZXT for $250, and have everything I need to convert my '78.You may not find one in this price range, but you will wind up spending a lot less this way. Just my .02 Roadman If 250 for a complete ZXT is out of ones price range, I would say the this turbo hobby is NOT for them. BTW, I was a write-up on compression ratio vs. boost somewhere(datsuns.com i think). To summarize, it said that high boost+low CR > moderate boost + high CR.
