Building An Rb26 For Response....

[Wongy]

Sorry for reviving old thread but in search of building a responsive setup too, bought the car with GT2860-5 already which i find laggy but don't want to go to the hassle of replacing the turbo's with say a -7 or -9, recently bought Tomei cam gears hoping to get a tune soon with those and get abit more torque low end, car currently makes 262KW, not searching for power atm, response is my main goal for now, any suggestions?

Mods are:

Arc airbox with Stock AFM

Power FC

GT2860-5

700cc injectors

HKS exhaust

Tomei Cam gears

Thanks

To clarify your question - you are looking for more spool/response without changing the turbos? They are way oversized for that power level.

[Wongy]

Yea,realised that dunno what previous owner had planned for it. So I guess if im chasing after response I'll have to look for someone who wants to swap turbos haha

Cam gears and a good tune might net you ~300rpm but that'll be best case scenario really at the end of the day.

Overall the only two 'simple' options to improve the response is capacity or downsizing turbos.

Got it,thanks for the responses,anyone want to swap -7 or -9's for my -5s with a cash adjustment? Haha,read on another thread that -7 and -9 good for response?am I correct? XD

[Piggaz]

-7, -9, -5, -10,

Response --->>>> power.

-5's on a 2.6 really ain't the best setup.... They really need a stroker or high comp on a 2.6.

[Wongy]

Thanks for the reply, will put up a post soon to see if someone wants to swap -5's for -9 or -7's with cash adjustment depending on condition of my turbo's as i don't know what condition they are in, obviously not expecting brand new -7's or -9's haha.

[Wongy]

So should I look for -7 or -9? Which one recommend for best response setup?

[Piggaz]

-7, -9, -5, -10.

[Wongy]

I already have -5s I have gt2860-5

[wolverine]

I think if you read from left to right you might find it is in order of response.

[Wongy]

Ahh,ok,sorry,my bad piggaz,Thanks Wolverine -7 it is

[XKLABA]

-9, -7, -5, -10.

FYP, in THAT order for response, tho there is very little in response difference between -9s and -7s, I had -7s and I believe the -9s are a better all round turbos

[Hadouken]

Say wut?!

If we are talking response and not better all round. There is no disputing that they go in the order of

7 9 5 10. This has been covered to death on multi page threads.

Should be stock ceramics, then -7 -9 -5 -10 T88

[sinistaGTR]

Go -9.... They are just awesome

[XKLABA]

When you had -9s and I had -7s yours was heaps better response wise, I found the -7s to not be that great

Stock ceramics FTW response wise though for sure

[GTRsean]

Keep in mind that was with stock cams too with -9's.

My tomei type b's I'm running now were a bit of a disappointment down low for off idle to 3000 rpm response.

I was surprised how good the stock cams are!

[Wongy]

Got advised there won't be much difference if i swapped out the -5's for -7 or -9, will just waste my money since i already have the -5's in, so adding tomei cam gears, tomei poncams, arp head studs, and valve springs, hopefully after a tune it will sharpen response abit more than it is now

[gtr jet]

Who told you that?

You could always stick some E85 in it for more mid range but other than that there's not much you can do without stroking it.
