5SGTE INFO Options

[Valo666]

So, i wanna turbo my motor, but dont wanna risk blowing another head. Ive poped two heads so far and the head on my new motor is ticking already. So im thinking that what i might do over the next little while is build up a hybrid 5sfe and 3sgte motor. I know ive already seen some info on a motor like this. I was thinking 5s block, 3s head, and oil pan, 5s intake manifold with throttel body, 2 bar map, tubular equal length turbo manifold, ct20 or a t3/t4 turbo. Just run ARP bolt on the head, and stock enternals in the block. Would this work?/what majour problems would i have making this motor? finding, buying, building the motor not a problem.

I think the big issue with it is the water jacket.. they dont seem to match up properly causing poor cooling of the block and head.

well, you cant use the 5s intake mani on the 3s
the best way to look at a 5sgte is to think of it as a 3s swap, with a 5s bottom end.
youll need to run the 3s ECU, and to actually benifit from the extra displacment, you'll need to run some form of EMS.

There is a great thread on the MR2 boards... www.mr2oc.com about the 5s-gte.

Like Pressure2 said - think of it as a 3s-gte swap plust a whole bunch of extra work. You won't be able to use stock 5s internals - they valve reliefs are wrong and the compression ratio would be off. 3s oil and water lines for the turbo don't bolt up to the 5s block. To take advantage of the displacement, you'll want to re-work the head... and just about everything else on the motor. It is in no way a simple project.

not a big issue for me. If i build the motor, im gonna send the block to my buddies shop because they have a hudge machine shop. Ill get him to mill out the waterjackets

so pretty much, buy a 3sgte, and a 5s block. As for the ems..i can get AEM ones for cheap for my work..like $1200 cheaper than list.

hell, 1200$ less than list?!?!?! i'd take one off your hands at that price!

Not quite... You still have to figure out the internals for the motor. Stock 5s internals won't work... (well, the crank will, but you need custom rods and pistons). You'll want to completely re-work the head to take advantage of the larger displacement.

Then the old fuel system, turbo, and everything else that goes along with a good build of a motor.

I guess the short answer is that yes, you *start* with a 3s-gte and a 5s block...

Yea..list price on a AEM EMS for a all trac or a mr2 is like $2464 or somethin stupid..my cost is like $1300. Gotta love the perks of the job. Like my new headlight bulbs..PIAA Extream White Plus. List = $146.85, my cost $52


fuel system no problem..have a friend who rebuilds supras..i can get 7mgte injectors and supra TT fuel pump for $150, turbo get a CT20 or im gonna buy a T3/T4 off my one of my 240sx buddies. Internals..that might cause a problem. W/e though..this is gonna be like an on going project. Im gonna start compliling the parts and build it as i go. I dont expect this motor to be done untill like..my second year in college.

Building a 5sgte is not as easy as it sounds... I thought it was a case of slap a 3s head on a 5s block, but noooooooooo.... its a little more than that... i have had a 5sgte sitting in my car .......YES...SITTING in my car now for 4 months and the only thing im waiting on is the custom intake. I have been let down by 3 fabricaters on this now and its driving me crazy.......BUT ITS DONE now...... and is going to the tuner for last min checks this week......i hope.....

any particular reason for not using a stock 3SGTE intake manifold, or aftermarket?

[ice23q]

The guy who is helping me with my build wants an intake with shorter runners and a larger tank using a 56mm throttle body for more toque.

ahh ic...be sure to get some pics!
