3.4-3400 Top End Swap

[93formulalt1]

Alright, I know the title of this thread makes some of you cringe, the thought of modifying a V6 for power. . . Yuck, I know. Well, in an article I found on several forums, you can make some impressive numbers by rebuilding a 3.4 RWD engine with low-compression pistons and swapping the top end off of a 3100 or 3400 FWD V6. This morning, my mom's 1995 Oldsmobile Ciera 3100 V6 fried a piston ring, so that engine is dead. Dad told me I could have the engine peices I needed to do the swap into my car, since her car is not worth rebuilding a motor in. I'm looking at doing a full rebuild with my car, building the s*** out of the bottom end, and swapping parts on to the top end. It should make for a pretty respectable V6. Just thought I'd let you guys know, I've been talking a lot about a V8 swap, but this just fell into my lap, and I think it's a decent way to be different and still make some decent #s. Just thought I'd let you know. Oh yeah, the Ciera had 180k on it when it died if I remember correctly. . . My Mom was aiming for 5 billion miles. . . lol She's had that car forever. I'll post up pics after I tear into that motor, Dad wants to take it to the junkyard soon, so I have to get all of my parts off soon. Anybody know where I can find forged internals for my 3.4 OHV RWD V6? Low compression?

So you are rebuilding your engine with using your mom's engine? Isn't that moving down the food chain? Not critisizing, just trying to figure out what the benefit would be.

Lowering compression will net you a loss in power unless you add some sort of forced induction.

Nick, I've heard of this and read a little about it. I think the heads will help, but most of the benefit is in the intake and exhaust manifolds. I think. While I'm sure you can get forged parts, I wouldn't bother doing it personally unless you are going to put a turbo, supercharger on it or spray it. Not saying not to rebuild it and use the parts, just saying I wouldn't put the extra expense into forged stuff unless you are going with spray or forced induction.

I would check into whether or not the parts on that car are worth putting on. I think you might need something a little newer but I'm not for sure, just something to check out. I'm not sure if the 95 fwd engine components are any better than your rwd is. Check it out.

Sounds like alot of time and expense for a net gain of more than likely nothing. Nick Just what you have to do, to make your car dependable. I'm not bashing you for trying, just stating My HONEST opinion.
