SOHC to DOHC swap???

[Stangfrk16]

My fiance blow her 93 sc1 engine, i got a great deal on my buddie's wrecked 91 sc2 motor. Does anyone know what is needed to swap these two... i was told i wouldn't have to swap the computer as long as i swap the head,so it would end up staying a SOHC... which is no problem, the car just needs to go is all.. but i was also told i could just swap it straight in.... I don't know much about saturn's...... tell you anything about a mustang!! anyway please help.. would prefer email to [email protected].... Thanks

It's way awesome to post that link, but what if a person wants to change out ONLY the head (and the other neccessary components), not the whole motor?

91 to 93 will not work crank sensor is differant engine will not run

oh man a sohc tbi to a dohc takes quite a bit. it needs the entire wiring harness in order to get it done.

No I'd use the DOHC tbi. I just want to put a DOHC head (I know I would need dohc intake and exhaust manifolds) on my 2000 SL1. I've heard it can be done, and isn't all that expensive or hard, just time consuming. Wiring I can do with my eyes closed. Only hard part for me is waiting for summer. Can this be done?

EDIT: just realized DOHC isn't tbi, now is it.

dohc is not tbi. your thinking of the 99 and newer vertical throttle bodies. its still mpfi, just with a vertical throttle body.

So it's basically not easier but more economical/efficient to swap the whole engine instead of just the head?

that depends on the condistion of the engine, goals, intentions, part compatiblity, time, money, tools, and skill

its far better off, because you are going to need the harness and pcm.

Well, CANCEL all of what I just posted.... Tuesday, Feb 7, I wrecked my beloved Saturn.

The appraisal guy is telling me 10 to 1 it will be totaled out.

DAMN!!

I'll post details later.

[saturnspeed_12]

oh man, that sucks.

[zippy_LiL_SL1]

Yeah, I'm just going to take the insurance money and try to find me a 98 SL2. That will take care of the DOHC problem..
