Just finalising the last few touches for the car, tyres came up..

Car;

power & delivery (snappy - progressive?);

tires (street choice, track choice?);

how you rate them;

GTS-T owners are welcomed to post to, could serve as a good key referance

cheers

well i guess it comes down to how much u wanna spend and how much u can fit under ur guards. any modification to ur guards? whats ur budget?

Il spend what Il need to spend, but would prefer going down a cheaper path. That's why id like to see what people are running..

Rims in choice are 33 gtr wheel 9' wide, so have approximately 255's to play with.

I put some Toyo T1R's on recently in 245/40 on R34 18x9s - were not too bad at the start.

My suspension was shot so fixed all that up rear cradle off new bushes everywhere, new arms, bars etc and all the camber caster etc set up.

Still wasn't overly impressed with them - but just over the past few weeks they have really started to get better and better as they have worn in.

They are now freaking amazing in the wet - I think they grip better than when it's dry!! Went up out the back of Healsville yesterday through a good 10km of 80km/h tight twisty rally esque back road and they did not skip a beat on wet, sometimes raining road. Put the 300 odd kw down without a question.

In the dry they are still reasonable, but the rubber is quite firm so they are not going to be overly impressive - will last longer though so fit in with a limited budget. Great mid-performance tyre for the price.

what use are you talking about? circuit racing? casual circuit days with some street use? all street use with the odd track day? drag racing? casual drag days with mostly street? or just high performance road tyres? this makes a big difference to what is suitable or not.

Such a hard question to answer as BB mentioned.

For example i had 255/45/17 semi comps on and with a laggy"ish" big single turned them hard in the dry when it came on full song. But then with twins, 30more kw atw and a more linear delivery of torque and power, 235/45/17 chaiwanese crap were doing very well in a straight line. Corners were a whole new story with them though....

what ever category you fall into, rather then just leaching area specific information for myself this could be a valuable reference to people. The stickied thread doesn't exactly cover all the variable's; power & application, Buying the wrong set of tire's for your car can be a costly mistake.

But being more to the point, I want some rubber which will fit on a 9' rim which will handle the car on the street through it's run in period, dyno tune's & street duties (T04z).. probably a bit ahead of myself if a 255/265 will handle a rwd dyno.

Yeah the toyo range are a great tire, used to take my t1r kitted gtr with 225's to the track .. lol.. Got 2nd in my class, mind you on a stock-ish gtr. Not sure how they would handle more power thought.

Yeah definitely not a great track tire... Maybe some R888's or RA1's

Do you have two sets of rims?

This is something I need to tackle soonish, another set of 18x9's and some tarmac rally rubber.

Have tried the Bridgestone RE55s SR2 (I think - slightly older tread pattern than the current model) at ~300rwkw and they were fantastic, but barely lasted through targa - really noticed a big drop off in grip by day 4. They were around $500 a corner I think.

yeah 2 sets, 32 and 33gtr rims... 32 wheels are useless to me 8' and only 16' doesn't leave much room for brake upgrade's..

i had gtr with t04z and 575rwhp

had 235/45/17 nangkang ns2 on 17x9 buddy clubs

handled the power and put it down well, not the greatest tyre in the world but very cheap... more than enough grip around the corners on the street to loose your licence

suspension work plays a huge part... wind camber out of the rear and get some angle in your subframe and it will work wonders!

at a mild output of 220kwrw i've been happy enough with the Federal RS semi slicks (595's?) 255*35ZR*18 on the rear and 225 on the front - RWD. they seem to stay put if there's no clutch tappin'' but break free nicely with a little juice in the wet ...

Re; Nankangs - use Mr Searchy to find other peoples opinions, but from what I remember, NS1s are scary dangerous with no grip, NS2s are only a little better. Other cheapish stuff like federal 595SS or falken 452 were rated much better grip wise.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
