ok i got a question, i got a 1jz rite now and i want to do the 1.5jz, now i was told by alot of ppl that the 2jz ge wasnt a good block to go with because it cant handle the boost unbuilt, and they said i was better off to go with the 2jz gte block instead..is that tru?.....i plan on runing a gt35r for now with 550's and an autronic ecu..what do you guys think?
2jz ge??

yea thats wut i heard as well, but then again ive heard ppl pushing out like 6 700hp outta non turbo blocks, i dunno i gess wut im saying is that, is it possible?......i have a non turbo block just waitng to be dropped in, but if its not worth it then i won't
thought the GE and GTE internals were identical. Well, except for the GE pistons having higher compression yes?

yes. the GE pistons are still dished too lol...
nothing a headgasket doesn't fix.
Oh, and to you oil squirter bandwagoneers, just buy em from toyota and install them. Most high hp 2JZ's run GE blocks because when your 1000+, the oil squirters actually hurt performance.
What would be the benefit of running a high hp motor without oil squirters? Any links or support for this statement?Ric said:

Ignorant statement. Using a head gasket to vary compression modifies the amount of squish and quench. Having a more complete quench actually is more important than half of a point or so of compression ratio. And more importantly there is a line of thinking that no small measure of horsepower is derived by managing "squish". Squish is related to the creation of maximized turbulence in the quench area as the piston reaches TDC. It is believed that when the distance from the top of the flat part of the piston to the flat part of the combustion chamber (technically the deck of the head) is made to be .040" to .060" in, max turbulence occurs. The closer the better. Many engine builders think when the piston just barely touches the head, but so lightly (maybe with a micron of clearance) as to not cause damage, squish is perfect.
What we do with N/A ->T cars is not optimal. But it is an inexpensive way to squeeze power out of an N/A car without replacing the entire engine.
But making sound like a GE with a thick headgasket is as good, if not superior, to a purpose built turbo motor is factually incorrect.
Side by side, a GTE motor will always outperform and outlast a GE when all other things are equal.

You do realize that GE motors aren't machined for squirters? There aren't any holes in the lower oil gallery for them. It's not plug an play...
Ric said:
Where the hell do you get your information from?
None of the 1,000+ RWHP 2JZ's I've built used a GE block, or eliminated oil squirters. Not even on purpose built world championship winning NDRA motors.
Additionally, squirters are for engine longevity and detonation protection, not power production.

That spec is well within the tolerances of any J series Toyota motor. You aren't talking about enough power for it to matter much one way or the other...
GT35R with 550's isn't anything to worry about on a JZ motor. It's not even breaking a sweat with that baby snail.

I'll do it just to post on supramania that Ric is my hero.
not that I'm a 1/4 mile guy or anything. 9 seconds just seems too fast for me.:evil2:
