Gt28rs too small for a 3.0 imo

1jz-gte also came in the mkiii supra. and you are wrong, na-t guys only stand by na-t cuz they don't have all the information. the gte is better period.

How can you say that? it's truly on what the goals are... If I wanted something to get me to 300 RWHP around 8 psi... how is a GTE going to out do the GE? Please explain that to me. I would want a higher compression engine if my goal was only 8 psi. I would spool that turbo faster then the GTE just because of the compression. Reliability would have a lot to do with how it was tuned and what it was tuned with. I would love to have a GTE trust me... but it's not the only solution.

alot of us have future plans for big power on the ge block. it is well known it can take up to 1000hp on the stock block and at those power levels the fact that it doesnt have oil squirters is a good thing. builders will usually remove them. the gte head is pretty equal to the ge head except for the cam pickups and marginally better flow. even the stock cams in a ge are close to the gte specs
People say the distributor is ugly, but It works and personally I don't mind how a GE looks with a 7m cps and vvti coilpacks, its pretty nice actually.
when you go standalone on a ge you dont have to get a DLI to amp up the ignition (even with the distributor). not to mention your waterneck is on the proper side of the engine, i think that factors into the look as well.

if you can replace a headgasket, Na-T might be for you!!
build it once and build it right, with the ge you havent already paid for a bunch of parts you dont need, you dont have to pay to get the harness in, its already there just add what you need and your good to go.

the gte head is designed for a turbo engine and the ge head is designed for a normal engine. you can slap a turbo to the ge and even put a front facing manifold on but the way the engine responds just wont be as good as with that gte head.
vvt-i igniter & coil packs without a DLI can be run on the gte too. the 2jz-gte vvt-i even comes with them.

prove it.
the ge head flows better on the intake and a little worse on exhaust side
ge intake manifold is also better (even though its ugly the air is more balanced to each cylinder.
ge also responds better in most cases due to the higher compression = faster response/quicker spool and better low end out of boost

regardless...tell us technically how the gte is a better "turbo" engine minus the lower compression = more boost on pump gas

Oh jeez guys, not again!

Wasn't there a special thread recently made (by a mod) specifically for this debate?

please stop misleading people with information that is wrong. have you ever even seen both next to eachother?
there is a thread on supraforums with proof that the heads flow pretty much on par with eachother and clearly you havent seen the charts floating around. the 2jz-gte head is based of the 3s-gte head and the 2jz-ge head is just a slightly modified 2jzgte head (for pickups), not a totally redesigned head .
The heads are almost identical, they respond exactly the same. the main difference is the intake manifold and cam/crank sensor pickups.

Everyone knows you can put vvti coilpacks on a gte, but what about all the money you spent getting a gte which uses the old type of coils.

can you post a link? I would like to read up on that...

I am not talking about the headflow but the way the top part (head) of the cylinder is designed.

Do you mean that the combustion chamber of the gte is optimized for forced induction ? Thats fine, but if the flow is overall similar between the two heads the chamber differences will be minimized because the flow rates are so close. In the end flow is the great equalizer, if you can't move air efficiently you can't make power.

a link for the flow rate?
also i was off..the intake is better on the gte and ge barely(not enough to make a difference) edges out the gte in exhaust..sorry i was backwards.

a lot of you have great and valid points,
im doing the work my self. and i was thinking aristo motor.
im just afraid of dumping all that money in a GE motor and it still not being reliable in terms of boost. knowing me the last thing i want is another blown engine.

any pointers on making the ge reliable?
i havent figured out a budget yet. since i am still not back into an SC yet. I've got my eye on one. And am currently in negociations with this individual. hopefully will be picking the car up with in a few months.

but i know boost is my goal, and i've been doing some research on this forum. I miss my Soarer that i had it was just too much fun! i want another boosted SC

thanks for your opinion guys keep it coming

the only thing i can think of is the combustion chamber and the quench..which is good for both engines..this is more talked about when mixing parts..ie putting gte pistons in a ge block with ge head..the quench isnt as good as it would of been using a gte head...but the same goes for the ge..using stock pistons with stock head will provide the best quench ..thats why it was designed specifically for..

the only reason the gte is considered better for boost is the low compression which is safer and more reliable especially when these motors first came out..however in this day and age with the tuning technology that we have its much better to run a higher compression( of course a ton of variables are at play but if you aren't looking for ridiculous numbers street driven on pump gas then its going to be best to run higher compression then 8.5:1 )

@Turbo?

If you want to run a lot of boost you will need to change the ge head gasket to the gte head gasket. The gte gasket is thicker which lowers the static compression ratio of the ge engine and makes able to handle higher boost on pump gas.
