34 GTR rims are 18x9 +30 Chris. It's a good ball-park for decent wheel fitment for 34 GTT's

Cool, so 18x9.5 + 34 would probably fit OK at the front and no worries at the rear I'm guessing. The hard part for me is getting me head around the offsets!

Being 12.7mm wider but sitting in 4mm more they'd poke out 8.7mm more than 34R rims? Does that calculation sound about right?

If I run the same size/offset front and back, will the track me the same front and back? The tyres I have now are 235/40's and if possible I'd like to use them, as they are good quality tyres

yeah i reckon so. The picture on the previous page of the blue 34 GTT you put up had wheel offsets of 18x9.5 +20 running 235 40 18's, which has a small amount of stretch and poke.

No problems running same size rim/tyre front and rear mate, at least you can rotate them to get decent mileage out of them

Ok nice. That fitment at the front is probably a bit too aggressive for what I'm after - but a 34 offset as opposed to a 20 should sit in nicely I guessing.

C'mon tax return!

correct, and doit!!

GTR are 9" +30 and fit nice, but could be a little more.

Chris head to my build thread.

I have a set of 2.2.1's

18x9.5 +22

All round fitment and I love it.

Nice, they do seem to fit well. I'm guessing that a 34 will have very similar fit

So can anyone tell me what offset I need for my 20x9 inch ring to fit inside the guard on my r33 gtst ?

About +15 will give you a pretty flush fitting.

+10 will give you hectic stance

Not sure how the guards will like it though.

These tyres are for the front.

So how wide do you think i can go on the rear?

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
