Hks Gt-rs Spool Time?

[Street Show]

Just wanted to know if anyone has these or know someone who does and how do they like them and when do they start to spool and when is it at full boost?

on the rb26 in twin form they will come a fair bit late as they are much larger than n1's and 2530's. have a look in the rb26 turbo upgrade thread as they have been covered before. you really need a built engine to get the most out of them and rev rev rev. i would expect somewhere near 5800rpm ?

Dirtgarage here did a swap from 2530 to GT-RS

Do a search, i think the end result was he should have stuck with the 2530's

yeah also have a look for OZGTR97V i think his name was

he ran twin gt-rs on his 26 and said they were too big for a mild 26

I was running GTRS's on a stock motor for a while. They were a bit laggy...but when I dropped in a set of 260 deg PONCAMS, the improvement was huge.

On full load in the higher gears, I was seeing full boost (1.3ish bar) at about 4800RPM

i believe he also said that they would have come alive with more aggressive cams and a bigger capacity engine. as many people have said, they r suited perfectly to the rb30 gtr

[paulr33]

is there a point where big twins it pointless

and its just easier and cheaper to go big single

and probably more efficient ?

[shanef]

thats the problem paul, u cant get a straight answer on that one, everyone says it comes down to set-up and what the purpose of the car is.

I'm contemplating going a set of gt3037's for the rb2630 just to see how 'laggy' they really are. Yes they will be able to make massive power (~900hp), but then a set of GT-RS's would be able to make ~700hp but have way better response. I spose you cant really tell until someone tries them out.

[paulr33]

why not big single gt40 instead ?

[shanef]

caus once i go single it'll be a pain in the ass to 'convert' it back to twin, i presume

hmmm After I sell my H2 I'm getting the N1 block and the hks stroker kit and the many upgrades that go with this. So it sounds like I'm just gonna have to get both and try them both and see which ones I like the best

Thanks for the help

This is my setup. See comments in the RB26 thread or PM me if you want specific info on the GT-RS terbs with an HKS 2.8L kit.

Hi Gav, long time! How are the GTRS's serving you so far, still chuffed with the choice?!

The big question IS: now that youve had them a while, are you used to the power and thinking that you could use more!!!!?? obviously your pretty much at the top of the low mount twin food chain!
