2JZ?

[JustAPhase]

Ive been searching the web a lot but havent found much. I was wondering whether the 2JZ-GTE pistons would work in the GE? I know the rods are the same but I read something on piston clearances. Also, if I find a non VVTi Supra Turbo head, cant I bolt that up to the GE block?

Pistons fit from GTE to GE.
Yes the GTE head works but you're going to need a new wiring harness anyway.

www.supraforums.com

that is where you should be looking.

vipstylecars is where you go to ask how many degrees you should be cambering your 11j +5's haha.

:D ::)

Yeah. Well I remember seeing one or two members that had Turbo GS's, so I thought they might have chimed in.

it's going to cost about the same to just buy a front clip from a GS. there was a guy on supra-forums, his thread is stickied at the top of the NA forum. its going NA-turbo, and he said it cost about 5500-6k, and that was a 'round' estimate. meaning its just a ball park figure. besides, if you buy the front clip, you have pretty much everything you need. just rip out your old motor, put in the new one, and do a little wiring between the 2 harnesses.

Um you need to swap the engine harness and then redo some pinouts in the NA harnes. the NA harness will never accept the tt and dosent even have pinouts for things like a boost controler. A 2jz clip will cost some bucks you would be better off using available parts in the states like the supra to do your swap. I just swaped a NA ca auto to SRDET manule. There is no way you can compare whats involved.

Save yourself the headache or rebuilding a GE to a GTE and just buy a GTE motor from the get go.

GTE's have oil squirters/passageways that the GE's do not have.

Plus having the GTE gives you the better flowing head and ample amount of parts to work with the head vs. the GE head casting.

And also on the topic of boosting a GE (called an NA-T), you would need to imply a thicker head gasket to bring the compression ratio down to a boost tollerable level (3mm from Boost logic gives you an 8.5:1 down from the stock 10:1 !!!).

Then you have to go with the HKS DLI for extra spark, the stock distributor cannot put out enough power to give a good enough spark to the plugs under boost. The stock plugs tend to litterally "blow out" under boosted atmospheres.

Injectors, need to be upgraded. Stock are 330cc.
Fuel pump is a neccesity.
Intake manifold and pipe routing is not in the best location. heat soaking is an issue with the intake piping running directly over the turbo.

The AFM needs to be upgraded to a Lexus V8 unit, or you could go stand alone and maybe short cut to a piggy back ECU that could incorporate a MAP sensor translation.

Bunch of other odds and ends that I did not list.

Again, just buy a 2jz-gte and be done with it. The stock turbo's are good for 450whp. Thats more than enough to get your blood pumping on the highway while cruising in style. LOL

I have to disagree on some things

1. Stock ignition will hold to 500 RWHP. That means distributor, coil, and wires.

2. Stock injectors are not 330cc I have flowed and tested 5 different GE sets they are 280cc and have the data sheets.

3. Stock bottom end on GE is just as strong as GTE. Pistons are the main difference so are the piston oil squirters. GE is cheaper and you can toss in a BL gasket for a lot less than buying a motor. There are plenty of turbokits available like the Boostwerx kit to make the cost almost the same.

4. VPC/SAFC combo is best for piggy back. MAP ECU is great and so is the MAP ECU 2. These are probably your best bet.

5. Change that tranny out the stock auto in the GE is good for about 350 RWHP and then they go fast. The 5 speed W58 is good for about 500RWHP with light throttle inputs (roll on the throttle) but will break with anywhere from stock to 400 RWHP with hard driving.

6. If you have a VVTi motor just get the headgasket and the Arp headstuds. Get the Cheap XS Power kit and boost it for about 5K you can have 400 RWHP. I did it it can be done.

Happy boosting.
