When you make the conversion on a Naturally Aspirated (NA) 2JZGE engine to a turbo, you must remember that you are working with an engine that was designed for no-boost, therefore the compression ratio out of Japan is 10:1. This is the reason you are limited to 7-9psi of boost on the conversions, simply because the added compression from boost and the 10:1 ratio is too much for street gas.

This is why we have teamed with XS again to bring you a complete 1.3mm headgasket kit with all new seals to make this the most comprehensive 2JZGE headgasket kit in the market.

Going NA-T and want a headgasket that will allow you to boost to 17PSI without fear? I now stock these gasket kits. These are custom kits that include every gasket and seal in the motor.

You will receive the following:

Multi-piece metal headgasket 1.3mm thick

Front Cover Seal

Valve Cover Seals

O-Rings

VC Nut Seal

Front crank seal

Rear crank seal

Cam seals Stem seals

etc.... EVERY engine seal

Gaskets:

Intake

Throttle Body

EGR

Exhaust I ntake mid

etc...... EVERY engine gasket

This kit comes with a 1.3mm thick high quality multilayer steel headgasket. Using the 1.3mm HG will yield a compression ratio of 9.2:1 - optimal for street driving and 17 psi of boost - great trade of compression and boost.

I strongly suggest that if you are doing your head gasket you do your front crank seal, cam seals, stem seals and intake/distributor gaskets. You may as well, you'll be looking right at them at that time. A great value!
