Between 4100-4400rpm for that boost. I can't do much more as the Mickey thompson tyres just can't take it. It's a lot of torque, enough to throw my soarer which is 1720kg with me in it over the 60ft mark in a best of 1.595 seconds so far. That sort of 60ft time on a big single without nitrous is nearly unheard of on a 2.5L engine.

And you can't use a dyno either to compare cause everyone uses different ramp rates. I've seen figures from 10-20 and all in between for ramp rates. The difference between these two figures plays a big part in boost response and eventual power output at the wheels. The big figure for me is how long it takes to build boost on the converter when I'm drag racing as I don't use nitrous. At moment I can build to 23psi in about 4-5 seconds depending on how I use the throttle initially. Electronic EBC has helped heaps in getting it on even faster.

I'm the one chris davey is referring to I can lock the stall converter on my auto and also manual shift it so it's very close to a manual. This was done in 3rd gear (1:1) on flat road not a dyno. No offence to you guys or to the RB25DET in general, but I find it funny how a lot of the posts here seem to have great concerns about the engine holding together. Just not a problem with 1jz-gte. I have run even higher boost, it just loves it, except i have to pull out masses of timing at anything over 20psi+ on 100ron fuel. Seems the turbo is good for around 25-26psi, but the fuel can't really cope with that boost. It has been interesting reading about the water injection that the mafia has done, especially how he has put in another 10 more degrees of timing. I know my setup on 24psi I'm running about 10 degrees of timing at around max torque, another 10 on top of that would help hugely. We did notice about a 5-6rwkw gain per degree of timing at the 21-22psi mark. I assume however that gain would get lower as the timing got closer to the optimal timing.

Hi all, I know this is a skyline forum with rb25's, but I thought I would post it anyway, as you may have a friend with a 1jz powered vehicle who is after what I have forsale. Turbo package $2600; *Genuine Garett T04E hi-flowed (watercooled)0.7AR rear housing, Unknown front. The turbo had been rebuilt 15,000kms ago with 360degree bearing. *Stainless manifold *50mm wastegate *3" dump pipe (custom made) with V-band clamp *Turbosmart type III BOV *Piping from turbo to FMIC (stainless) *Turbo blanket *braided oil feed line *braided water lines Injectors $450 *US Supra (low impedence side feed, bolt on) 550cc injectors *Custom resistor pack (Make injectors high impedence so can run with factory ecu) Prices exclude postage. Buyers pay postage. The car pumped out 264.9rwkw at 16psi. This package has been carefully put together and suits people who wants big midrange and good top end with very little lag. The turbo starts spooling at 2.5K and fullboost is at 3.8K. Any questions please post it here.
