I am planning on running the NA-T parts. I have done quite a bit of browsing on this forum and a few others. From what I understand the GE has a higher compression ratio than the GTE. I have searched alot of places that sell pistons/rods and they do not have aftermarket pistons for the GE, just the GTE. So my question is, will GTE pistons fit in a GE?

same crap minus the passage ways for the oil squirters. Yes they will fit, though its unlikely you really need upgraded pistons.

I plan on going this route and everything I have seen is people have taken the GE well above 500hp on stock internals. I think you will be good. The tranny and clutch will need to be done before internal work.

Where would the weakpoints in the bottom end be located? I have heard the wrist pins are weak, are they? Are there any others?

95 Integra

Head gasket and youre good. Wrist pins? I havent heard that and highly highly doubt that the wrist pins fail. The failures dont seem to be one common thing (other then the head gasket), though Im going to say that the "weak" point is probably the pistons. You really dont need to worry about the bottom end, the tranny seems to be the bigger factor.

BoostLogic put a T71 kit on an na-t and made 720 rwhp @ 30psi on the stock bottom end + hg.

the pistons and rods are the same thing minus the dishing on the tt pistons the NA bottom end will hold plenty of power ive seen a buddy of mine make over 800 wheel on stock NA bottom end simple a cometic head gasket and arp head studs you wont have a problem

Thats not 100% true, the pistons are slightly different (rods/crank are identical), but the pistons on the GTE motor has the oil gallery (a hollow aluminum pipe cast into the piston) so the oil from the oil squirter is pumped through the piston for better cooling. Also the ringlands have different coatings. Now some people will say none of that matters, but its more important then people give it credit for being that toyota engineers know about 1 billion times more then them and thought it important enough to include on the GTE motor. Though it wont do any good on your GE motor since you dont have oil squirters and you stock bottom end is more then capable of handling anything you'll likely be throwing at it (being in the 900-1000 crank hp range).

I have about 180k miles on my motor as it is. I am used to honda motors as that is what got me into the car industry. With a Honda motor it would be imperative to rebuild before boosting, is it necessary with the 2JZ?

95 Integra

Thats funny considering I boosted my stock gsr w/ 112k on it. At 180k its probably time for a rebuild (ie, new gaskets, rings, bearings and headgasket), but thats because its relatively cheap to do assuming you can handle the task yourself.

Are you implying that there is no need to replace the rods/pistons?

Psionic

Just do a compression/leak down test. If they are ok, you dont have to rebuild. DaveH ran a 9sec quarter on a 220k mile na-t setup. Couple of members here are over 200k and went na-t. These engines are super-strong.
