Default what flange? or DP

Was thinking of getting some used pieced kit for 400. Greddy manifold with some garrett ar .48 turbo, IC, SAFC. Doesn't have DP though and I can't find this 4 bolt design when I search. Anyone know what would fit or where and how much it might cost to make a down pipe?

Looks like a 300zx t25 turbo. Flanges can be found at ztune (google it). You're way better off to stay away from it though, there's nothing else on the market that uses that flange.

Darn. Thanks. Yeah, was trying to find it for a while. 300zx does look like it. So for 400 stay away. comes with IC, blitz blow off, gagues. What if he goes lower?

It spooled like mad on my car, made 16psi at 3000 rpm, but it has no top end at all. Check out my dyno graph:


You can see that hp and torque drop off really fast. By redline it's making less then 100torque, and only about 130hp. It was great for off the line and city driving. The car would just take off, but not good for drag racing situations.

I got my turbo for $100, and had a custom downpipe made for it. I soon wanted to upgrade to something larger and then found that I had no upgrade options. Everything else is a 5 bolt flange. I ended up selling everything and getting a new setup. I would suggest not getting into it.

it's a start, but you still need a lot more parts and its a manifold that's not very reliable.

Yikes, thats a crazy chart. That does drop off pretty fast. Really, I was just looking for some fun around the streets. like 150-170. Would anyone even buy that turbo? So not worth $400.....$300 for the kit?
