Hi guys,

I've done some research and I want to buy a GT-RS turbo.

However, I was concerened about the lag issue.

Could the people who have a GT-RS turbo tell me when they hit full boost (at what RPM) and what boost they are running?

I am aiming to get around 240RWKW from my car.

Current mods include:

Full 3.5" straight through exhaust

GReddy Front mount intercooler

Splitfire coil packs

Power FC

Bosch 040 Fuel pump

Cold air intake system with pod and heat shield

Boost controller set to 12 PSI.

Currently, my car is putting out 195 RWKW with the current mods. Should I be able to reach 240 RWKW with the GT-RS with bigger injectors (550 CC)?

I've also read about the HKS 2530 but I read that it only could pull out about 220 RWKW. Is there a turbo that is in between the GT-RS and the HKS 2530 and that isn't so laggy?

Cheers!

This was on my previous set-up (rb25)

- Tomei cams

- Head porting

- std exhaust manifold

- std plenum

- 3" turbo-back exhaust

- 550cc inj

- Wolf3D V4 ecu

- and all other supporting mods

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
