nissan never released any stock figures at the wheels, only at the flywheel

based on what i have seen on SAU from stock R32's including my own, i would say:

auto - 100rwkw

manual - 110rwkw

gains from just a cat-back and nothing else? probably about 10-15rwkw...

Yeah, they prodused 158kw at the flywheel i think it was, theres a formula to give an approx of what that would be at the wheels, but the above figures seem pretty accurate i would say.

If you are interested in a power increase, i would seriously consider a turbo back exhast with high flowed cat as opposed to a cat back, which is not that likely to give much of a performance increase.

you will definately see a power increase with a cat-back.. as i said 10-15rwkw

obviously you will see an even biger increase if you do the whole exhaust (dump/front pipe, cat, cat-back) - more like 20-25rwkw..

but everyone has a budget do whatever fits into that budget!

but those figures i quoted were pretty accurate i think for a stock gtst and i mean out of the factory style...

thanks thirtytwo... that figure is kW at the flywheel

as the power makes its way though the drivetrain, energy in the form of movement (kinetic energy) is lost as heat and noise. Thus by the time is makes it to the tyres to move the car forward, much of the energy has been lost.

that is what is measured by a dynanometer.. power at the wheels... which is 100rwkw auto and 110rwkw manual

My R32 GTS-T has just a 3 inch HKS cat back and pod filter and returned 177.6rwhp. I'm sure you could expect similar results with the Trust 3 inch cat back and similar intake. See link for my original thread (including dyno printout).

    • Something I meant to say when we were chatting the other night about having an open trailer floor being great to work on a car, but you've never used the feature... It's a great place to park a car after doing suspension component changes, and do the tightening of all the bushes with the car sitting at full ride height. Especially when you don't have a 4 post hoist!
    • That is way more science than even I would use. I just eyeball it, not even accounting for the non-verticality of the tape measure when held on the lip and the centre at the same time. +/- 2mm is good enough for the girls I go out with.
    • So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.
    • So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them
    • I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.
