Getting More Power: Super/turbocharger?

[ItsVince725]

1995 is probably obd "1.5" not very tunable, although, some have cracked it. I would switch to a 7730 or go full obd2 either way though.

Going GM to GM shouldn't be too hard...I'm sure there are OBD-1/1.5 to OBD-II conversion kits that allow you to take a OBD-II ECM and related harnesses and wire it up to an older car. I'd hope that a computer swap wouldn't require all new wiring harnesses.

Given this is a 1995, wouldn't I have to get a more modern ECM too? A newer engine would be OBD-II, and I'm assuming a 1995 car is OBD-I.

whole 3500's have gotten pretty cheap, and may be an option too, but they take a little more work on the install side.

Yeah, I'll definitely contact him about that.

But this is somewhere in the future where I can afford to plunk down...I don't even know how much to get a 3400 from a Grand Am for an engine swap.

I don't see why not, but I would have to ask Ben on that one.

now you're talk'n!

Question is, could I order Stage 2 heads as a starter and then have them re-ported to Stage 3 later? That would be very useful, I could have a high performance NA engine and then upgrade to turbo power when I decide it's not fast enough.

yes, he does require a core, and the way you just described is the only way I will do an engine swap!

Stage 2 seems best if I don't already have a turbo kit fabbed up, but if I plan on getting a turbo anyway, I might as well go Stage 3.

it would be a much more strait forward swap that's for sure, and could still make good power. Ben say's that stage 3 3400 heads actually outflow the 3500 heads, so a set of those and a cam, and you could be having some real fun!

Do those require cores? If they do, I would have to buy the engine and sit on it a while until the customized heads get back and then swap it in.

Swapping an engine into your daily driver and then making it non-driveable is pretty silly.

[ericjon262]

Oh right, I almost forgot the Grand Am had a 3400.

Would probably have to do a little cutting because I doubt the mounts are in the exact same places, but it would otherwise fit like a glove.

considering you have a N-body, i'd look at the later N-bodies(00+ grand am and the like), probably more likely to have the correct mounts and stuff.

the block itself, not too different dimensionally.... but the heads/cam carriers/intake/timing gear take up a LOT of room, even in a W-body.

Good to know. So the easiest and cheapest option is to find a pushrod 3400 from a minivan or something and go from there?
