Not sure, trying to get the build sheet from the guy. If I get this set up it will be a forged rotating assembly, gen v, cam, ported heads, and some nitrous. since I’m not spending the money on an intercooler I’d be ok with 350hp with a 75hp shot on top for fun. ---

> [@ultradriver10000](#): > > 3400 is an easy good swap @misteroman I did this swap on a '93 Z24. I had it running and back on the road in less than two weeks. (With working and only spending a couple hours at a time on it.) That was my first major car project too. It could easily be done in a weekend. Mine put down 200 WHP and 220 WTQ. Not bad for a little cavy. ---

I remember on the on cavy website, guy put a 3.5 or 3500 if u will and had nightmare s with it . I remember the one big problem was something with linkage.

the 3400 is pretty much a newer version of the 3100 so it pretty much all bolts up. ---

I really considered doing something but should do something with the iroc first. Had it back for 6 yrs now and haven’t even touched it yet!!! Very reliable. I beat the hell out of that car and it never gave me a problem. I was seriously impressed with how well it held up. 3.5s are basically the updated versions of the 3400. If you find a clean, low miles engine, I’m sure it would be fine. ---

I could be wrong but its a 60° v6, I think the power steering would have to be relocated and a custom pulley made. prob a lot easier to turbo. I turbo’d a 3400(non dohc) by replicating the cross pipe with a turbo manifold for a single turbo, turbo sat just above the tranny. ---

I think you’d need a custom lower intake manifold, or side mount it. I wouldn’t bother. ---

Ya my mistake, forgot the 3800 is a 90°. same bellhousing as the 60° motors I believe.
