Opinions on a GTE with GE pistons, for my toyota 4x4 pickup

[shaeff]

so, i realized that i have most all the parts to do a stock build on a spare block that i have that's already machined for use. i have a GTE motor with new internals ('89+ motor) but it has a hole in the block that was patched up. (the internals ARE new though)

i also have my old N/A motor that got rodknock. between my spares and whatnot, i have enough parts to build a turbo motor out of my spare already-prepped turbo block. i'm planning to put it in my '94 toyota 4x4 pickup.

i figure that if i use the higher compression pistons from the GE motor, the '89+ crank from the turbo motor, new bearings, etc... and do a stock rebuild with ARP hardware and a MHG, that this motor would be reliable for a daily driver, and get decent fuel mileage. i don't mind filling up with high octane fuel.

i want to make about 250-300rwhp, which will be pretty easy considering that i'll most likely use the GE pistons, which would also give me a bit more low end grunt, like i need in the truck. the little 22re is just too underpowered in stock form, and i figure for the cost of mods to it, that i could just build a nice mild 7M. i'll be using a stock ct-26, (rebuilt by MDC of course) and i'm not set on getting even 250rwhp. stock for stock, i'll be pretty much doubling the amount of horsepower and torque simply swapping from 22re->7m.

i want some opinions, on using the GE pistons. remember, i use it as a truck. it's not meant to be super-pretty, but i do keep it clean. it doesn't need to be an absolute monster. and it needs to be reliable.

i don't want people posting saying : "DO IT! JUST DO IT!". i want this to be a valid, informative topic.

thanks,

if you do this you must make a deatail step by step on how to do it


lol

Nothing wrong with that, if you keep the boost limited to 8 psi, you will be plenty safe. You will still need to resize the crank and the big end of the rods to match your new bearings. If you are swaping cranks, you will want to line bore the mains to match the other crank. You will also nee to re-hone the bores to put a fresh cross hatch, and to match the different pistons to that block.

yes, i want to keep the boost low. (and i know i have to with the higher CR and no real tuning capabilities). i've got a damn good machinist, so that will all be taken care of. the cylanders were already honed and have a perfect cross hatch on them. i'm going to bring all the parts to him to inspect, just to be sure, (and he does it for free for me). he's built several 7m's before, so he's familiar with them as well.

There were a few 7MGE turbo kits back in the late 80's. Low boost is just fine.

Chris,

I did plenty of research before i went NA-T on using GE pistons. I dont see you having any problems as long as your not going for super high horsepower, or boost, i can't really see you running into any problems piston wise!

i'm not really concerned with the motor lasting, i guess i'm really just looking for people's opinion on a higher compression turbo motor.

perhaps traction will be an issue... who knows? heh. i guess i'll find out.
