Ive got 18s on my R33 so would you be suggesting that when i go to the drags (as i am planning to go to WSID soon) that i put the stock 16s back on?

Wouldnt they reduce my grip level though when im taking off?

What would you reckon is my best course of action here 2rismo?

large rims requires fitting lower profile tyres with less sidewall flex, so you might experience tyre-hop or tyre skipping on the tarmac as you launch hard, reducing traction. in drag racing optimum traction is gained if ur car can squat down enough during hard launch. some larger rims also increases unsprung weight and requires more effort from the engine to spin it, therefore can reduce your acceleration rate.

that's an option, but IMO 18" lightweight usually are pretty expensive and a rubber that wide are expensive too... especially if u had semi slicks and doing burnouts will wear it out quicker and send u broke after a few drag meets :-P

Stick the stockies back on, deflate them toabout 18psi and off ya go.  You'll also accelerate quicker with the smaller rolling diameter.

Let us know how ya go...

thanks for the tip, i think i'll be putting the stockers back on. Will post up my results as it will be my first time at the drags :jump:

the thing is this. you max width, with a small wheel e.g. 15 inch to have max sidewall flex. the problem is 15 inch wheels are usually 6.5 inchs wide. which is shithouse.

It's like a balancing slider. if his 18s are 18 x 275, that is quite a bit wider than the stock tyres (205 or 225). if he's running nittos, the grip due to width may still be faster than the stockies even though they're heaps heavier.

Perfect wheel would be some nice light weight 15 x 10 inch wheels running slicks. yummy.

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
