Well that all depends on what turbos you are using and what spec they are.

So provide more information and people will be able to give you a rough estimate possibly.

As it also depends what fuel you choose, how much more timing etc etc.

And soild mounting the motor... ouch!

Generally most believe that around 300-330awkw is a safe limit on an internally standard RB26.

That said, I know of one car producing 450awkw on pump gas and nitrous with a stock bottom end that has done so for 2 years - Thats pure luck.

If you don't want to risk popping the engine, go conservative.

SPECCY FUEL MAY HAVE BUMPED THE HP UP, MAKEING IT HARDER TO GUESS HOW ON THE LIMIT YOU ARE!!! SPECCY FUEL WILL ALSO LIMIT THE CHANCE OF DET!!!!!!!!!!

SOLID MOUNTINGS CAN DAMAGE HEARING CAUSING ONE TO SHOUT!!!

On a quieter note, TO4, didn’t (aren’t you still) making much more the 350kw on a stock bottom end as well?

      After market rear camber arm adjustment

      By sonicii · Posted

      How much have you lowered?  I had 350Z springs in the rear and was able to pull the camber into factory spec with the factory arms on the rear, obviously the front ran negative camber as it isn't adjustable, but rotating the wheels regularly evened out the wear.

      R33 Fuel Pump & Brakes after alarm swap

      Either the installer needs to come back, you need an auto electrician, or you need to learn automotive electricals yourself.   First step Id look at is where that big thing came out of, is there still things unplugged at that location? Maybe they just forgot to put a relay in or something?

      Well, this is probably where a wiring diagram and a multimeter come into play.

      I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want.

      R33 GTST Axles

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.
