has anyone done this or heard of someone doing this?

Will the pistons interfere with the valves?

anyone know what needs to be done?

I know of a guy who did it in a corolla forum, but i thought i would ask here too.

Sure it'll work. Will just need a custom ECU and a few other odds and ends.

what type of gains do you think it would produce?

I know you need the3Shead and cam gears n stuff.. and a timing belt but from what I dont know...

what about head gaskets, what should be used?

look at club4ag.com's tech section.

I personally have been thinking about a 20v head swap, I just don't know what problems I'd run into as far as ECU goes...

I wonder what would happen if I tried to run a 20v head off of a 7a ecu >>

You would have to swap the wire harness just like the 3sgte swap. Here....To get the ball rolling.

Thanks for the help guys.

so does the 3SGE harness hook up to the 5SFE ECU?

What year 3SGE head should be used on a '94 5SFE block?

is the compression going to have to be raised? How much should be shaved off the head?

lol, lots of questions. >>

thanks again!

3sge head from a 4th gen GT-S? im looking for a word to describe that... oh yea, pointless. to do a good valuable, power gaining headswap, it will usually cost around as much as swapping the entire engine out. so unless u find some super great deal on a nice head and all the other ridiculous things u need for it to work, it is more productive to swap the engine. of course there are the people who want to be different and think the only way to do that is to do something that no one else has done and it ends up costing more and putting out less power, but its original. i do believe u would be the only guy with a 6th gen with this particular headswap. but is it worth your time and money? prolly not. with that head its hard to say if u would be doin any better than u are now. if u want power save up for a swap or a turbo or somethin like that. or, a much easier option have ur celi be ur show car and buy a car that actually is fast. thats gonna be my way of doin it. >>
