The tacho is the original from a 240sx, made to fit a 4cyl engine, so with the extra cyl it shows 1,5% more than the actual rpms.
let me show you my new setup. Vg30det, clevite bearings, Pte 5857 turbo, tial 38mm, apexi pod filter, 3" full exhaust, walbro 255, bosch 440cc, 89 z31t gearbox, 3.6 vlsd. For the moment the boost is at 1 bar. I just bought a profec ebc to boost it more. I also got tomei poncams that will soon be in my car. How much boost do you think is safe?
Drifting round servo pumps here would see any of us locked up, possible loss of license, with the offenders car taken away, and possibly compacted. Do you have a video of yourself drifting through an armaments store, or around people on a crowded pedestrian crossing, takes real skill to do that shit,
damn, the engine seem's to go so well in the s13 some people I used to know threw a built rb26dett into a 180 a while back with twin s15 turb's but ended up getting crashed by my mates son =[ the thing was an absolute weapon, and felt way to unsafe! too much peaky power for a light car. Im guessing the vg power curve would be a lot more controlable
