Sohc to Dohc
I was just wondering if anyone has or knows anyone that has done this swap. I have the list of things that i need to buy but im not sure exactly hard it will be to do it. My ending plans are ofcourse adding a turbo.
From what ive read the sohc engine can be turboed right now as it is with a custom exaust manifold, what are the differances in the potential in the engines? Im not trying to get an insane hp count, close as 200 as possible atleast.
Would it be, in your minds, smarter to turbo the sohc engine and save money for tunning?
Thanks for any answers you can give me, i am very serious about getting this done before the snow comes back.

"At least 200hp" is not little at all. If I were you, I'd find a low mileage DOHC engine and swap that in, then go from there. I hope you know that making a custom manifold for you SOHC engine will not be cheap at all. You might as well invest a few hundred more and get a DOHC. You'll have much more potential at the end. Just my opinion.

yea i was thinking about the dohc route, but out here in suv/truck land its hard to find a protege period. I dont want to go with a bpt because of the things i read in a thread on this board.

What have you read about the BPT? The arguments that the BPT is a little more flow restrictive than the BP? IMO, if you decide on a swap and you want to have a turbo motor, you might as well do a BPT swap and get everything over with at once. This, however, will be a bit more pricey.

alright, well i found a dohc engine close to where i am, figure ill just do that swap and then turbo it. Any suggestions on the turbo, the shop up here (almost dominated by honda) uses 15g's witch i was told is 5-8psi, is that enough to make a big differance?

5-8psi will net you about 190hp, about the same as a GTX, as the GTX has a stock boost of 5-8psi, but the boosted BP will show a bit bigger gain with the same psi than the BPT.
