The guy with twins is running 280 cams though, not exactly helping him spool early. The 8374 is a pretty big snail too.

Found this too. Its the Twins. Comments say pull starts at 3000rpm, ends at 4000rpm.

We're you hear that? I pulled the pics off GTROC, but there wasn't any other info.

A) Twin EFR 6258, on a 2.6L RB26, tomei 280 cams, mild headwork, stock intake manifold/tb B) Single EFR 8374 .92 a/r, Full-Race twinscroll manifold, on a 100% Stock RB26, Tomei Poncams are the only engine internal modification.

Apologies for bumping an old thread, but the images were still on the server, I just had to edit all the BBcode. Since I did all that work, its going up here for future reference.

I'm with the OP, I want to duplicate the SK kit. I'm in a worse spot though, being in Canada when most of the parts are made in Aus. I've been researching things for several days, looking at parts and alternatives. I already have adjustable FUCAs RUCAs and tension rods (easier to get here because they're the same as S13 and Z32 items), so I'm only looking for shocks, springs, and sways. Heres some of the data i've collected.

(comments from SK) The standard spring rates are around 3 kg/mm. Knowing the local conditions, aftermarket Australian spring makers upgrade that by 20-25% to allow for some lowering. Hence it is rare to see a Whiteline, Lovells, Kings etc spring rates over 4 kg/mm. The valving in the Group Buy R32GTR Bilsteins will handle up to 310 lbs/inch (5.5 kg/mm) on the front, which is around 40% more than what you currently have. The rear Bilsteins will handle up to 260 lbs/inch (4.5 kg/mm) which is around 25% more than what you currently have. The most common upgrade for the track day guys is 275/225 which works very well with the usual R type tyres (RE55, A048R, R888, D01 etc) R33GTR Bilsteins will handle slightly more spring rate, R32/R33GTST and R34GTT slightly less. front Whiteline spring is 165lb/in (2.92kg/mm) and the King spring is ~175lb/in (3.1kg/mm).
