2JZ-GTE short block and SC300 components?
Are the components mated to the SC300 pretty much the same as the Supra TT? (Upper pieces)
I ask because I am interested in a single Turbo upgrade, with SC300 parts (head, etc.), and a 2JZGTE short block. Basically removing the SC300 block and installing the 2JZGTE, with a Supra upgrade.
How much horsepower can the SC300 Auto and Manual transmissions withstand?

Well, from what it looks like the 2JZ-GTE BLOCK will bolt up to everything the GE has, so it looks like...
SC300 car $6500 (autotrader)
2JZGTE new short block $2200 (Toyota)
Turbo kit $5000 (Toyomoto)
Not too bad. For about $14K.
But it looks as if I'd be saving a lot of cash (and being as sucessful) with just an SC300, a Toyomoto kit, and a double head gasket. For about $11K.
I'd rather have a custom kit, but by the time I'd have everything together it'll be 2006.

The resulting increase in clearance volume changed the compression ratio from 10:1 to 8.4:1. Perfect for a turbo-charged motor. Next time, however, I probably would just go with a TT hg especially in combination with meth injection. In fact, it should be possible to run stock compression at high boost with chilled intake air using Derek's injection system.

I have been preaching this for MONTHs and motorheaddown finally proved it ...he and I BOTH used a 2mm headgasket (2.7mm uncompressed, as he said) and I swore up and down it would put the compression close to 8.5:1 and no one believed me. I kept telling people that a 3mm and double stacking was overkill and would give you 8.0:1 or lower compression ... and because of what he proved from the 2mm headgasket, I am still sure I am right
... and I STILL have an HKS 1.6mm headgasket laying here, brand new, for sale STILL, which would be perfect for an NA-T project. I only didn't use it because I was in the bandwagon thinking I needed a 3.0mm headgasket, and when they sent me the wrong gasket for the SECOND time, I figured screw it, and I used the 2.0mm that they sent me incorrectly after incorrectly sending me the 1.6mm ... so I have been sitting on it since.

Yeah if anything i would swap out the GE head for a GTE head before i went out and spent $2k on a GTE shortblock. Plus than you can use the oem supra TT head gasket and get what is it 8.875:1 compression!?!. I went all through the choices before i just said screw it and dropped the full GTE in.

Angel - Lance Ho Lung calculates two TT head gaskets with GE pistons to come out to 8.5:1, Larry Prebis calculates it to come out to 8.6:1. There are other reasons for doing it too, went thru this same topic in the SP63 thread, different pistons, lack of oil squirters, etc.
bmsport - Many believe the GE head to outflow the GTE head, so that would be a waste, and you can use the TT head gasket on both motors, GE and GTE, without having to swap the head.
