Whats going on guys so I was just going to stay with the stock twins but decided to go singlepost up pix in a little bit just finishing opening up the boxes.
sc300 engine is 2jz-ge. Non-turbo. If you have a gte it couldn't have come from an sc300. Lower flowing heads, less aggressive cams, different pistons, fewer piston oil squirters and different rods in the ge from the lexus. The GE and GTE in the supras both have the same connecting rods so they will hold similar power but not the case on all the other car models that the GE block went in. Different part numbers with really thin rods.
Beware if you go to add boost on this engine if it really is a SC300 engine.
^^ Jeff, I would assume that the OP had a SC300 that had a GTE swapped in already.
ah, that would make sense.
I thought all GE were the same until I saw some pics of the rods from supra GE and the other cars with GE and there was a noticeable difference in thickness.

The GE and GTE have the same *size* rods so they're interchangeable not the same lol. The only piston difference is the compression ratio really, and most high hp builds remove the oil squirters anyway. Only issue on the GE's is the ignition distributor, and different flange patterns on intake and exhaust. The GTE's have ignition problems even on lower levels of hp, so it's wise to upgrade to coil on plug ignition (OEM GM FTW). Seeing as OP is swapping engines, I assume he has an ecu that will let him do that. My buddy has 2 ge's, they're great motors. If the compression is an issue, fix it with some head studs and a thicker gasket.
GE's can make 600 without breaking a sweat. And GE's actually have slightly better flowing heads than GTE's...

any updates? I will be doing this swap in a month. I am working with tech2 performance for all the swap stuff they are a great shop and will get back to you same day. hope you made some progress.
GE and GTE rods are different as are the pistons as mentioned(additional oil squiters for the tops and diff oil pump) later VVTI are the ones with thinner rods vs 92-96 Supra\Aristo 2JZGTE's. Soarer's (aka sc300's) came with 1JZGTE's. GL op keep it up!
^+1 good to know man i did not know this. I thought the only difference was the VVTI. I will be getting a regular GTE then. thanks for the knowledge.
You could also buy a GE and have it rebuilt with GTE internals. That way you'd have a fresh engine for relatively cheap. Running Ge's can be had for as low as $800 bucks depending on condition. Most any machine shop could rebuild that 2j to slightly looser than stock specs without any issues, for not that much, and it would be a great engine. Or you could always upgrade the rods to eagles just to have the ARP hardware and be able to rev a bit higher (eagles are considered to be marginally better than stock rods, but they are a bit stronger and I believe lighter, but mainly have much better rod bolts).
My vote is get a GE, have it rebuilt with Eagles and GTE pistons.
As of late guys who rebuild actually prefer the GE to the GTE if in a USDM car (on club lex at least). They like just adding good pistons which actually don't require the design of the gte pistons which has oil squirters and can be prone to oil pump failure due to more oil requested. So the thinking is to just rebuild the GE with rods and forged pistons and use a 2jzgte oil pump. The real big difference is the intake manifold. GE has the intake run along the hot side of the turbo so yeah not good. Factor all of this in and for 2K you can get a used GTE motor generally good for 400HP with the proper intake design, turbos ecu etc..... Rebuilding the GE also doesn't require a custom harness (all jdm 2jzgte or 1jzgte will require custom harness work no matter what if in a LHD car) GE's are also cheap and readily available in the US. Both motors have good and bad points. Just gives people more options
