1g question
my friend just bought a 1991 awd talon for a grand, (e3b16g, 650 injectors, afc fuel management (not neo) walborough 255, full apexi exhaust, stock side mount, etc) thing is, the kid he bought it from melted a piston running 20 psi-ish on it a few months ago. one of the cylinder walls was scored, so were tearin it apart and he's gonna get the block bored to a .040 overbore (since its been bored .020 over before already the last time it blew up.) the stock compression ratio is like 7.something:1, but we were lookin on buschurs website and saw they sold 8.3:1 pistons ( these.. with wrist pins and rings included) for just under 500 bucks. how much boost would he be able to run safely with these pistons and the given mods with a good tune?

RE: 1g question
Those pistons... good rods... I say about 550whp and a max boost of mid-low 30s.

RE: 1g question
Sebba are you serious?! over 30psi on a 16g. Come on. I wouldnt run moer than 24psi on that turbo. However right now your weakest link is that SMIC. With that still in there your really risking running anything more than 20psi

RE: 1g question
those are forged pistons tho? it didnt say anything about them bein forged. but with the stock head (just p&p) with those pistons and a decent set of rods it would be able to handle about 20 on the smic? i told him his first 2 mods should be a fmic and a wideband. he's already got the afc fuel management like i said
|
RE: 1g question
Yea those two things really are needed. And i think i would stay at about 18psi until you can really tune it with the wideband. But thats just me. The last owner probably ran it way too lean. And i wouldnt want to risk it till you got the wideband and tuned

RE: 1g question
I thought he was asking how much the motor could handle lol Whoops.
|
RE: 1g question
with the mods your listing. I wouldnt run more than 15PSI untill tuned PROPERLY, then I wouldnt run more than 18 without a FMIC. then after that gets fixed I would say 20-22 on pump is all good. Obviously I think the internals can handle alot more than that as sebba also said.
and John no kidding it was running lean IT MELTED a piston |
