is there any diference between the block of the 2jz ge and 2jz gte? not rods and pistons just block alone? and are the cranks different?
what i want to do is pull the ge out of my sc300 and put in the gte. then pull the block off the ge and put new rods and pistons on the ge block and put the new stronger ge bottom end that i built out of the ge on the gte. granted the blocks and the cranks being the same. are they the same. is the gte a stronger block? is the stroke the same?
whats up

I think the only difference in the block alone is piston squirters, other than that the sump may be a little different, but probably not....

are the piston squirters guna make a huge difference?

KidPandJ

on a boosted motor i would think so, they keep them cooler

A good handful of guys run na-T with no problems for a long long time-- Usually when they do run into problems it's from a dead injector leaning out a cylinder and going boom-- or from running too lean overall and melting pistons --

For a 12 second pass-- you'll see little difference with them-- assuming your car's properly tuned--

If you use forged pistons-- you should be fine with a good solid fuel system and lowered comp. ratio-- and a good tune--

Guys do this with SR20's all day long with little problems, they usually melt down when you've run the car a lot and get too confident and run the absolute **** out of it over and over street racing and that sort of thing--

If you want you can drill your block for piston squirters-- but keep in mind that even motors with them still blow --- fuel starvation under a heavy load can do it every time. N/A motors do it too though..

Spun bearings is a problem that few speak of, but happens.
Along with the oil squirters on the block, the TT's have a higher capacity oil pump.
The TT block has the turbo oil supply on the right side, making it much easier to run for your turbo. My 2c

yeah, the only problem with oil squirters is that they drop the oil pressure. So its not a good idea to drill a block and put them in if it didnt come with them form the factory. Thats why motors that have them usually have bigger oil pumps- other than that theyre great, they lubricate and cool the pistons...

I'm betting the higher capacity system is available aftermarket also, and there's probably a setup with higher capacity than the stock TT system.... It prob. all bolts up too... Just a guess.. But it's cheaper for companies to use the same block casting, much cheaper.. That's how the sr20 is, the blocks are identical, just needs drilling for the squirters...

You can also run an external oil pump for your turbo if you're worried about pressure to it...

Psionic

Along with the squirters (which are rumored to fry oil at high pressures), I think the oil filter isnt located on the block itself. Other than that, the crank and rods are the same part numbers for both engines.

The only real benefit I can see with going gte is the ease of changing the spark plugs.

what dose the block have to do with the spark plugs/ the plugs are in the head/ im going to run the the gte head on a ge block....

Prob just use a thick metal h/g and you'll be fine unless you try to go freakish... Then some new mains and a balance + better pistons/rings should keep you goin.
