I don't think a 2F will fit, at least that's what I remember hearing in the past.

2JZ's can be expensive, if you're looking for 1,000+ HP, but I think a stock 2JZ is much more reasonable. All that being said, I've done ZERO 2JZ swaps, so who knows. LOL

I wasn’t thinking of the mighty 2F, more along the lines of one of the more modern straight sixes. But they still have similar displacements, so you’re probably right on fitment. So more likely a V6.

Thanks for the last round of responses, this is what I was looking for in terms of advice. I’m all for a 3.4 drivetrain, but they are now pretty long in the tooth. This leads me to the low price leader- GM. I imagine the 4.3 are also pretty hard to find with lower miles.

So the current toyota(???) V6 is a possibility. I did a little digging today and GM seems to have gone to i5/6 cylinders. I thought the low end silverados got a V6, so I need look into that.

I also did a little “build” researching and I saw mention that a 3.4 drivetrain swap required a body lift. Are the 1gen really tight on transmission space? Or was this guy going for a flat belly?

you don't really need a body kift if you place the engine on custom mounts. in a SAS situation.

I was debating between the 4R or a buggy build. In that time I missed the deal and someone else got it. I’ll keep looking. Thanks for all the great responses, if another deal falls in my lap I’ll be back.

I put a 2003 4.3 into my truck and it was the worse thing I ever did.If you going to go with a chevy engine get something before 1996 0b2 is a pain in the ass. It ran fine for 11 years but not that many miles on it. It stopped one day and has been a rock ever since. Replaced just about ever part in the last 2 years. It started out with the fuel pump ran 5 mins and never ran again. The fuel in this state did not help at all. It destroyed the new ac delco fuel pump. At this point it would have been smarter to put a 86 toyota turbo engine.It would have been plug and play. The 4.3 broke the frame first trip to Panimint valley. Replaced and reinforced the frame rails. The new ob2 engines are a pain .By the way YOU will need to become the expert because no one will touch a conversion they didn't do
