Stock 4age's and boost

[D-limo]

What sort of boost can stock 16V 4age's handle reliably? What power atw are we talking with a T25 sized turbo?

Is it possible to purchace decompression head gaskets for running more boost?

[gg004]

depends how its tuned. hich compression and turbos can go together only if they are properly tuned to run that way. if you just slap on a turbo and pump big boost in, it wont last long as the detanation will melt nice holes in your pistons

just do it to a gze. its cheaper and easier than forged internals for a 16V.

unless you are planning on using stock internals.... if youre going to use stock 16V internals i give you a week max before she blows

turb up a 3 rib

pretty common half the garage dori dudes run 15psi on stock 3 ribs

if you want 150+ gze other wise upto 150 is sweet

I was going to say, about 120-150rwkw will be fine. At that power level, gearbox diff and engine are all getting near their limit (thrashing them, that is). So kinda a good level to stick at

yeh try break everything all at once

old mate used to put the gze stuff on a ge and had no probs with 12psi he was belting that for a while.

ive been driving mine daily for about 4 months.
the owner before me had it for just under a year.
and the owner before that put it all together...
I have a stock smallport with turbo and complete gze eletrics (comp, CAS, wiring, everything)
I run about 4psi normally.

Ive always wondered how much i can safely run without too much worry..

*wait, it has gze cam covers, maybe that stops it from blowing up

Thanks for reply's..

I would be happy with around 130-140rwkw


*Just to clarify stock driveline should hold up ok at this power level if I don't intend on drifting?

130-150 rwkw will be fine if you take it easy..... my one of those ran for 2 years and then, only the head gasket went no damage to internals

<div class='quotetop'>QUOTE (mr2drift @ Jan 10 2008, 08:36 PM) </div>i run a big port 16v and have the turbo manifold to suit. im running a greddy emanage on a jdm ecu. is it true that all i need to do now is get a 4efte map sensor to read the positive boost and im sweet?

also how much would i be looking at for purchasing the necessary flexi pipe shit that toyota uses on supras etc? more or less than getting some staino piping made to suit?
