DEFINITIVE HP GUIDE FOR RB26 2023 600HP BEST RESPONSE
GDZ32 replied to Comm's topic in R Series (R30, R31, R32, R33, R34)
Plenty of ways to chase response. - Stroker Kits - E85 - 4.11 Diff Gears - 3.7 Final Drive - Vcam - Carbon Driveshafts - Turbo Choice I've got a 2.8 with Vcam, Carbon driveshaft and -5's. Response is great even on 98 and relatively old turbos. If you can, drive different setups and see what you prefer -
R32 GTR clutch (twin plate va tripple plate)
GDZ32 replied to timmy94's topic in R Series (R30, R31, R32, R33, R34)
Just get a Nismo Coppermix and call it a day. -
They can make 500whp but the supporting mods you'd require would be extremely costly. There is a R34 GTR in Melbourne making 390wkw at 21/21psi, but it's 2.8 with Vcam on E85. I'd just go single to make things easy.

Cam gears and poncams next??

ATP TURBO's GARRETT GEN2 GTX2860R upgrade (Twins)
GDZ32 replied to Stixbnr32's topic in Engines & Forced Induction
I've got regular -5's too and ran out of turbo at 420wkw on 98. I then looked into these newer GTX variants and they all claim to have a new blade design with 500% more flow blah blah blah. No real world results have been proven though. My opinion is don't waste all that money for new twin turbos, labour and tune. The gains will be miniscule...if any. -
Just buy WARGTR. It's for sale and has a Nitto 3.2L making 1400hp with all the bells and whistles.

HKS Advanced Heritage RB26 Concept
GDZ32 replied to joshuaho96's topic in R Series (R30, R31, R32, R33, R34)
Didn't HKS build some exhaust Vcam prototypes a while back? T thought the conclusion was that they would be too expensive for the gains. -
You didn't purchase the Vcam Step2 by any chance? Then swap it with a Step1 at RacePace?

I've got -5's with a 2.8 and Vcam. Perfect pairing for a nice street car imo. Responsive on 98 too I also dont have anxiety every time a HWY Patrol car drive past me in Melbourne

2.8 purely for the sound. Plus no chopping

Did i buy -5 turbos or Garrett N1 equivalents- Confused
GDZ32 replied to djvoodoo's topic in Engines & Forced Induction
Discopotato knows what's up -
Series1 Bayside Blue and Midnight Purple cars had black engine bays. Series 2 was body colour. Other colours were body colour though, my white BNR34 Vspec came with a white engine bay. Although the paint is matt and dull. Series 1 will have blue build plate, Series 2 will have silver build plate, unless it's a Nur of course.

GDZ32 replied to djvoodoo's topic in Engines & Forced Induction
Type B drop in cams. 260° intake and exhaust with 9.15mm lift. Stock R34 GTR crank which was a new item, Eagle rods and CP Pistons in a N1 block. The motor was built in 2009 too. Was a good setup with the gearing on the 32. A bit laggy in a hairpin but otherwise really good. Plus made decent power on a safe 98 tune so cant complain. -

GDZ32 replied to djvoodoo's topic in Engines & Forced Induction
I had these on my R32 GTR. Definitley smaller than the 2860-5's I have on my R34 GTR. They're a great turbo, mine made 340wkw at 20psi on 98Ron on the RacePace dyno with a built 2.6 and Tomei drop in cams -
Do a skid
-
They all claim to have 1 million percent more flow and made more power on made up dyno graphs, by whoever is building the turbos, but hardly ever translate into real world gains. I've seen it so many times. Then again a lot of people just care about a higher number on their dyno graph

HKS Vcam Step 1 to step 2+ without buying uprate kit q's?
GDZ32 replied to brian_s30z's topic in Engines & Forced Induction
Just leave the Step 1 as it'll work magic on a stock or built motor, or wait and get the HKS Step2 pistons and Vcam Step2 at the same time. My car has run Step1 Type-A Vcam on a HKS Step2 2.8 with -5's and then I upgraded to Vcam Step2, the gains are minimal, if none at all. I wouldn't be modifying anything when the motor gets built. -
Any reason you're going 3.5' exhaust and not 4'? I've just gone from a 3.5' to a 4' system on 98RON. This allowed me to run more boost (Ignition timing was close at only 18psi using -5's with the 3.5'). With the 4' exhaust and 4psi of boost added, I gained 40kw at the wheels. I'd definitely be going 4' if you're paying for a custom system anyway.

RacePace did a Gen 1 GTX2860 on a 2.8 with E85. It made 421wkw at 20/21psi which was a pretty decent result. I ran out of turbo on my -5's at 419wkw with my 2.8 on 98RON.

I can confirm LOL
