ok been talking amongst my mates and we dont know whether they will fit

18x8.5s +17 offset on R33 GTS-t fronts - (im sure the rears will be fine)

what do you guys reckon?

will i have to roll the guards? is it hard? where my front bar hooks up to the quarterpanels (closest to the tyre) is already dodgey because I have ripped the front bar off a few times in the past.

what do you guys think? is there any sort of online calculator that someone has made? :rofl:

cheers

I've currently got 18x9" +30 on the front of mine and they fit perfect... yours will sit almost the same (less width but more offset) you will need to be running some neg camber tho... around 1.5º should do it... and maybe a 225 tire for added clearance (I run 235's)

I have 18x9" +30 on the front of mine too. Fills the guards nicely.. I'm using 235s

I assume +17 will just stick out a little more, but your rims will be half an inch thinner.

I reckon they'll fit easy, unless I don't know what I'm waffling on about. (I don't)

yeh im hoping i can get away with stretching a tyre over them - im going to full lock the car later today and see where it is closest... i dont know what camber i have atm

so if your offset is 30 and mine is 17 that means mine should poke out 13mm more than yours IF we had the same width rim but considering mine is .5 of an inch skinnier and there are 25.4mm in an inch that means mine are 12.7mm skinnier

so can someone confirm that mine (by my math - it might be wrong) is going to poke out .3mm more than your rims NickR33... is that right?

hehe thanks

Your maths is almost right but you have to realise that half of that 12.7mm is going to be on the inside of the rim. So your rim will be 6.35mm further in due to width but 13mm further out due to offset.

Net effect is 5.65mm further out. If you run a skinnier tyre and theres no issues with rubbing then it should be fine...

will definately need to pump the guards for legal fit - plus your track will be illegal (but bloody close) which should only be a problem if you go over the pits and they measure them.

You will probably need to run a 215 tyre or the tyres may rub - or you pump extra and remove the inner guard (plastic) or fit glass wider guards.

Getting similar offset on the rear will require rather more massaging of the guards than the fronts (just in case you were thinking of going down that path)

I believe Tech9tyres can pump guards for you if your not up to it, they used to a while back.

rears are 18x9.5 at +25

thanks for the advice bud

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler

      Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
