3s-gte engines

[marvis]

They will be beams but?

[rthy]

did they fix the oil pressure problems in the gen3 when converting to rwd?

[driftke70]

probably good to note too that the gen 3 comes from the factory with forged internals and ballanced crank. Good for 500 od hp on standard internals "from what ive heard"

also something to note is the angle they sit on in fwd form, they tilt back in celicas a fair way,

here is some info too.

they never really had problems, people just made dodge sumps

I always thought the Gen 2 and 3 were a fair bit better then the Gen 1 for internal componite strength. The Gen 2 also has the small port head which can be a plus if the head is ported were it makes horsepower without loosing airspeed through the Bigport.

the beams sump/windage/pickup system is spot on. QR 5th gear proven The only real difference between gen 3 and beams is an extra oil drain at the rear of the head. Ive putting a gen 3.5 (ST215 motor) in an 86 upright atm, and I have a beams next to it to copy off so I plan to replicate the oil drain addition. Will get pics along the way and do a tech article.

you rekon i should?

gen 1 and 2 have the same intake ports, i have a gen2 intake on my gen1.

gen 1 and 2 gte are internally similar, its at gen 3 where it all changes (just about everything)

gen 3 is where the ports change. also have shim under bucket.

gen 1 na is the weakest by far, smaller crank, different crank pcd even. smallest oil pump, ect ect. but i am still confident it can hold together with some boost if i keep the rev cut down, i will probably set it at just over 6500rpm. i am only aiming for 140-160 rwkw. i dont really understand why anyone would want more, maybe i have been driving na 4age ae6s for too long, but that is double the power i would usually have (or close to it).

the oil control problem is a function of sump design. toymodders kill them sometimes when rwd, but then IP guys do not.. IP guys run them NA at BIG rpms..

medwins seems to be going fine and its only a gen2.

ill get some pics and you can decide. im still 50/50

the 3sgte im getting is out of a 90 model gt4, so is that a gen2 i think checked on autospeed , all the fab work i can do myself i just dont no a hell of alot about converting it to rear ie which gearbox, flywheel, bellhousing, inlet manifold all that shit to use
