3sge with 3sgte after market piston and rods, I need help on the block Options

[funnys_tears]

hey i got question about 3sge and 3sgte,
will i run out of oil and it mess up my rob bearing and main bearing, it making noise like knocking, but
"What iF i put 3sgte low compressure after market piston and rod into the 3sge block can that able to work, is that gonna have any problem with the block and does the compressure make any difference, or gonna be the same.. i haven't done anything like this put 3sgte piston into 3sge block,.. how about the head of 3sge, can i still use the 3rd 3sge head on the 3sge block but with 3sgte after market pitson and rod, will that change the compressure...can any get me the information of that.. aright thank..[b]

If your just putting the beams intake manifold on the non-beams head, you should be fine.

The head doesn't make the motor higher compression, only the pistons do that (in this case). The NA cams have a longer duration then the turbo cams, but its really not that much (like 5 degrees). The cam journals are the same - I had snapped the exhaust cam on my 3SGE and replaced it with the turbo's cam. The valve systems are identical, as are the cylinder head combustion chambers.

I dont have any HP numbers, as I've only had the car running a couple of months. I'm hoping to get it on the dyno this spring, before upgrading to a bigger turbo. I am pushing 14psi on a Mitsu 14b.

The thing is, once you change the pistons and add a turbo, it IS essentially a 3SGTE. You can run just as much boost and produce just as much power as a 3SGTE, providing you do the same supporting mods. The first bottleneck for the 3SGE is the injectors, which are the same as the 5SFE. Luckily its an easy upgrade, and Apexi makes a Power-FC for the 3rd gen 3SGE motor to control the extra fuel and boost. I dont know why more people dont go the 3SGE route for projects.

If you really wanted to get forged high-compression pistons, your best bet would be sending in the stock pistsons to a manufature to make a clone of. I had a set done by CP this way. But, higher compression = lower boost levels.
