35SFGE "the frankenstein"

[SW21T]

yea thats what im going to use, also i have no choice if i want a 5sgte lol

[Hsien-Ko MR2]

I too plan to do this. Only Ill be referring to mine as a 5sfe 'T'. Why, you ask? Why not?

[SW21T]

you mean the 5sfte right?? No theres nothing wrong with it, its what i currently have in my MR2

[Hsien-Ko MR2]

What are you getting HP wise with that?

[SW21T]

haven't got to dyno, I'm only running 8psi and my estimate is near the 200's maybe 180hp-190hp...Not all sure

[Hsien-Ko MR2]

At the wheels? Or crank? Guess the numbers wont be too different, as the cars weigh nothing.

You can use either. A 3S crank gives you a better rod ratio and less displacement. A 5S crank gives more displacement, but worse RR (assuming you don't go custom rod lengths and pistons).

The 5SFE and 3SGTE share the same effective rod length. The big end bores differ, however, so you don't machine the crank to fit the block. You modify the crank for the rod you plan to use. 5S crank with forged 5S rods and 3S crank with 3S rods means no machining necessary, 5S crank with 3S rods will require you to machine the rod journals on the crank.

Awesome! I hope you continue to do research and make this dream a reality for yourself when the time comes.

Thanks Sang, I think I'll use the 5s crank with forged 5s rods, that way no machining is required..but thanks when i get started I'll let you know so you can help me just incase I get stumped since I'm still learning.
