The par gear sets are amazing mate. I had billet selector forks in it too.I had mine for 5-6 years. With power over 800hp and 28 inch drag tyre it was doing its job.

Upgraded ID injectors/fuel rail will see upwards of the 550rwkw it's already produced as well, still retaining the standard head...

We are looking forward to what we can get out of it before the new head goes on that's for sure!!

Traction will definitely be an issue for this car but it will be one hell of a lot of fun to drive!! :)

We (Mercury Motorsport) also have almost completed a JUN 2.7 stroker in an RB26 with an HKS T51 SPL turbo (also in a 33 GTST). Will be interesting to compare the two! :D

What rear housing is on the turbo?

Seem turbo is lazy, 35psi is at 7250 rpm looking at the graph. Check just incase your wastegates are leaking, or a boost leak?

if all ok, id be looking for a small rear housing.

hay mate, its how its tuned, he has given me some drivability. there arent any boost leaks and def not going a smaller rear housing. if anything id go a bigger turbo like the GTX45r, it would be perfect! with the 42r i can short change at 6000rpm and it still hard on boost on the gear change so its very generous on its power band. first thing is first and thats to get rid of the borrowed standard head and put my build one back on. maybe look at a 900hp plus with it all on. which is just pointless anyway.

ta for having a think about it though.

took it for a run before its got the bigger wheels and wider tires and before it gets this head work put in

did a 11.98 @ 138mph

had it on maybe 40% throttle in 1st and 2nd, any more and it spun and axle hopped then flat foot in 3rd and 4th. but its on the limiter over the line in 4th.

did this on 17 inch wheels so the new 19s will have me still changing hard over the line for more mph and the tires a a 3 year old federal 275, there shit. new tires will we be anywhere from a 305 to a 335 just havent brought them yet so cant tell ya.

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Appreciate the feedback. It is street car, but not a daily. Last week I got a quote from a good exhaust shop for a decat, one which is bolt-on, bolt-off to be easily replaceable. I got quoted for around €150. I usually do push the motor, but I wasn't in this case to make sure that no damage is done until I get the cat sorted. I think it's best to also ask the exhaust shop for the other option and see what they can do. If (big if) I were to decat though, would it be best to tune the car or would the stock ECU handle it? As far as I know, the stock ECU is not tunable and that would require additional purchases.

      As above, definitely bash it or get it replaced with a high flow unit.

      Duncan's V37.......race car?

      By Duncan · Posted

      Right, its been a while for updating this car, but I made some small but important progress today. In the end I bought an Ecutek dongle from the Australian distributor Tunehouse (for local hardware support) but have gone with a remote tune from Racebox in the US (because they have done millions of these, and I could not find any tuner where I could access the tune anyway as they are all password locked). The App is reasonably easy to work with, but the PC software reminds me of Haltech's ECU Manager that you need to use with the Plat Pro ECUs, it is a nightmare.  Anyway, I sent the details over, got back a tune file and a request for data logs. I finally got a chance to access a private test track today as they want redline logs in 3rd and 4th, and have sent them back for the first round of reviews. The main difference in the tune is going from 1.0 (stock) to 1.3 bar (19psi), although I'm sure is a lot of other stuff in the background. Keeping in mind this is a dead stock car with 125,000klm, this is what the App's performance test claimed: Before After Interesting to note that both 400m tests had the same terminal speed (158klm/h) but different ETs. And no, the speed limiter seems to be higher than that at 186kl/h. Summary of the key logged parameters for the 3rd and 4th gear runs were: Those little turbos were certainly whizzing at 200,000rpm+.  Also I'm really not that excited about oil pressure 55psi at redline so I think I'll go thicker than 5w30 (nissan recommend 0w20....) and see if that improves it. Other than that (and the big boost spike....) everything looks good as a start to me.
