MKIV Supra Single Turbo Conversion

[VR4]

Hope you brace that manifold. Heard a lot of things about the rps manifolds cracking.

Em -- That's not the first time I've heard that... :-/


ppi -- Not braced; doesn't need it. Some of these manifolds have been around for 10+ years now -- high mileage units may develop cracks, but they certainly aren't prone to it. I know of one that's been on 4 different cars and probably has 100k cumulative miles and it's still good as new, structurally. I had a GReddy T88 manifold that was cracked halfway around the T4 flange. Not something that they are known for, but it happens.

It's alive! Still on stock fuel, so I'm limited to 16-17psi until the fuel system goes in. No signs of leaning out yet, so I may have a little bit left to go. A/F is in the upper 10's/lower 11's at WOT without any correction. It's absofuckinglutely ridiculously fun to drive as-is. The power delivery is insane; spool is even better than I was expecting. I may dyno it just so I can find the true limit of the fuel system -- should be 525RWHP or so. I've seen 10's in the 130MPH range on completely stock fuel; I may give that a shot.


all over again..!

Those seem like the perfect mods. I would DD that beast day in day out as it is on stock fuel.
