I was reading a write up on a comparison on the GT2530(I think) and the GT-RS in zoom I think it was, was a very goof read. I'll scan it in and post it if anyone was keen to have a look?

 

The end result was that although the GT-RS lacked a little bit in top end the mid range response was awesome. It was picked over the GT2530 but price is a bit of a turn off.

Could you send me a scan of this article. I'm very interested in the GT-RS turbo but now I wonder.

Thanks

I have been doing some research, and it LOOKS to me based on the comments throughout here on GT2530s etc that a TD05-big 16G from a Mitsubishi EVO3 (and some others) would do a similar job.

I think with many of the turbos designed for 2L 4cyl they would make a noticeable amount less on the RB25.. If you could get it rebuilt to more suitable A/R ratios and the like could be an idea though, esp if you're getting it for dirt cheap.

I have been looking at the GT-RS .. at $2500 for a "full kit" (+ taxes etc) its worth thinking about. I am not sure whether i want massive HP numbers to start with on a stock bottom end, and that looks like it fits the bill.

So consensus is around 240rwkw or so with a nice broad powerband? A dyno graph for rb25 would be very nice to see :)

Thought the gtrs was a bigger turbo - people seem to be getting more power from these than 2835??!!

strictly speaking, 2835 is a 400ps rated turbo, exactly the same as GT-RS.

Its the 2835Pro and 2835R that have the 420ps rating. Hence more power from the 2835Pro's that people such as grepin (287rwkw?) are getting. I think that was at 1.2 bar. So far ive heard a GTRS pull 250rwkw at 1bar, so they arent too far apart.

Hi guys late post.I got this quote from www.horsepowerinabox.com

I can do the GT2535 in the T3 flange internal gated for $1750, but not the

GT2530.

We also do a 500hp core unit with a .70 comp cover for the RB25 as a bolt on

Internal gate for $2150.

Regards

Do any of you know the garret gt2535 turbo's housing specs.Are they the same as HKS?

I also found a link to a site where HKS is compared to garret. clickey

There is a mountain of "garrett" vs "HKS" discussion in this very forum... its amazing

Do You guys know if garrett turbos are rated in ps atw or ate(at the engine)??Likewise with HKS.

pretty much all the turbos I know rate at the engine.. its only rough anyhow.. too many factors can vary it around.

Least you know the HKS is going to come out of the box working :D

NICE:)...all done at BD4s?...i bet Paul loves you:)

SAS have a good name around the traps of not leaning on engines too hard, and dyno figures being on the money...so very nice results with what should be a strong reliable combo:thumbsup:

Last question...what boost is it running to make that power and where is boost pressure being measured?

thizzle that is an awesome power curve! looks to have about the same response as my 2530, but with stronger top end! -I hope im impressed by my 2835pro!

Looking at that curve the GTRS could be THE ultimate daily-driver/weekend racer turbo upgrade!

      Great info @tidi0x  Will definitely be handy for others and maybe me if I decide to keep the shit box H pattern.

      Bumping this up one last time.... I wanted to follow up on the clutch slave issue. I realized that what the issue comes down to is the pocket is flat milled, and the cylinder does not want rest flat. So in order to mount it correctly you will need to make a spacer for the fingers so the cylinder is floating. I took two plates of aluminum, drilled some holes and was good. I did still need to make the relief cuts in the bell housing, as even with the spacer the bleed section still interferes. The OE bell housing the mounting holes are raised from the housing.

      If the event in USA goes ahead will be interesting as it seems the rules will get more cars over here. Apparently the track is laguna seca too. Yeah s15, if I get a the lower dash trims, centre console and change front cross member to standard LCA position will fit clubsprint. See how rules are as i would rather do complete widebody than a bolt on flare to run the 295 with proper clearance.

      If the car is legal height I can't see it being an issue. Found a thread on reddit that might offer some insight.   I got a ticket from a copper in QLD for my S15 being too low. They had this wheel thing on a stick that they put under the car and it hit my exhaust. Anyhow went to an exhaust shop to get the exhaust tucked up/hung a little higher and I wound the coilovers up a smidge. Don't think I even had to go back to the police station unlike when I got defected for having a carbon bonnet when I brought the S15 from the ACT to QLD and had to replace it and then rock up at a police station and have a yougish female officer who knew nothing about cars confirm that I had changed bonnets. Should have just painted the carbon bonnet yellow to match the rest of the car lol
