weak rods and the wrong compression ratio in that engine. if you do some meth injection im sure you can squeeze in another 2 psi safe for daily driving and normal abuse. don't take my word for it though, i've never personally dealt with turbocharging the LAP, just speaking from experience with similar setups.

It isn't about just throwing more boost at it. Keep it at 8psi...put meth on it...and turn up the timing till you get a blip of knock...then back it down a degree or 2. Done. Much more power.

What about the l61? I'm thinking about getting bigger injectors and converting to e-85. Would that be too much for the stock internals? I have the zzp stage 2 turbo kit at 8 psi right now...

E85 is nothing more than a cleaned out gas tank, new fuel filter that can handle the E85 and way bigger injectors and a tune. Like I've heard and I don't know since the L61 can't handle lots of boost because of weak rods I'd go with more timing and fuel then I would a boost increase

Yeah, I don't wanna turn the boost up but if i can pull a little more timing that would be nice. I will eventually be getting rods, pistons, sleeves, and possibly turbo grind cams. Someone else said all I need is bigger injectors and a retune to convert to e-85.

Right you do...running E85 is basically like 113 octane all the time. Also...race tolerant o2 sensors wouldn't be a bad idea either. I have them in the GTP and its nice to be able to run 93 on the street and 114? I think it is...at the strip...where most stock sensors hate anything over 94-96 and start to foul out.

Extra boost is fine as long as you don't put your power levels above what the stock internals can handle.
