Pair of twin scrolls with quick spool valves sandwiched in. Don't have divided manifolds. I'm not doing a twin set up so what I'm running wouldn't really benefit this. Something along the lines of a gt35r and a GT45. You want something gun? Pair of EFR 6262s from borg warner. Divided equal length tubular manifolds. Dude in the US did it and car went off like a rocket ship. The side by side comparison between these and disco potatoes was amazing - same curve, 1000 rpm earlier, with more top end too.
derp, 6258s. sorry it's been ages since I was reading about this RB26, 6258 in red and 2860RS in blue
you sure they aren't -10's ? HKS GTRS (GT2871R -10) is mistaken for GT28RS alot of the time EDIT : A quick search and yes they are gt2871r -10's .
You should look up , and jump on the mr2 forums. Twins are old. But yes way better. There are more tircks you can do that work really well with the twin scroll. Tbh im a little supprized that BB didnt go with it.
