I was thinking this would be easier is the only reason I bring it up. Those return pumps are spendy I know, but then you would have all kinds of room, cooler charge, more sleeper when you open the hood, and you don't have to fab an exhaust manifold to take the heat. It would be pretty cool as I've never seen one done. I did read of a guy doing this on the cheap on his cavalier. Said it worked great. Just spitballing.

If I didn't off road, i would think about a rear mount setup.

I got the turbo and vortech FMU today. Also had a small air-to-air intercooler laying around. I'll hopefully start on it soon.

The rear mounts are kinda popular in the F body world due to limited underhood space but frankly I'm not impressed by the power returns. Not sure if it's related to heat loss reducing turbo efficiency or spool time or both.

Frankly I wonder about OEM 3.8 gm roots blowers mounted to a 4.0 intake for a cheap and easy-ish boost.

good luck with the build

I agree completely about rear mount setups. Turbos work off heat energy. The farther from the engine a turbo is, the less efficient it is. Another funny thing is, I was a tech at a Buick dealership for a few years and actually have a eaton m90 (3800 supercharger) sitting in the garage. Lol. I was gonna use it, but it's not that easy.

I'm a big time f-body guy, maybe this is why I'm a fan of them. I only recommend a rear for the ease of it, and cooler charge. Downfalls will be have to run intake in the cabin, if going off-road, and the lack of heat makes it work not as well. But on a stock 4.0 that thing will wheel 8 psi any day no problem. Have a friend with an sts making 10psi pushing through 210 runner afrs on a 396. If building an all out race setup stay away, but for street friendly power, easy, they are tough to beat

I like turtles

Well I have almost everything I need to start the project. Hopefully next week I'll tear into it.

I thought the Borg Warner s475's were more around that power level? I'll give it a try tho on my firebird. Lol.
