Has anyone tried putting a HKS 2540 on an rb20det? I know that they are a straight bolt-on. However, I was just wondering whether or not they would produce good power in single form? I'd like to put one on a r32 gts-t and take it with me for my future gt-r but I am unsure about all the different types/sizes. Which a/r is best for twin setup and single setup?

Any help/comments/thoughts would help!

Thanks to all.


:cool:

It depends on what you want out of your car. My take on it is for the street he smaller A/R, and for drag a lager A/R. You have to remember its the marriage between the cam, air velocity, port size, A/F ratio, compression, turbo, timing, etc. That makes it work.

I can not answer your question, since I have only dealt with superchargers.

Looking at the way R33 likes his power band with two 2540 for his RB26DETT, with a single on a 2.0 it should spool a little fast. So, it lok to be a good idea, but like I have said before I am no expert, but have spent many hours doing research. If I am way off, the other guys can correct me.

A GT2530 which i image is a little smaller can make 220rwkw on a RB20DET in a R32 that equates to 12sec 1/4's

If 2540s work well being hooked to 3 cylinders for each turbo, a single 2540 hooked to 4 cylinders would, I imagine, raaaaaaaaaawk!:cool: But I wonder whether the manifold needs to be customised for that kind of application. I suppose the tried and tested td05 or td06 could be a better choice.

RB20 is a six cylinder, I6 like RB26.

I thought it was a 4, man you learn something new eveyday. Thanks Han:D

How big are those pistons, the size of a D battery:confused:

:D :D :D :D :D :biggrin2: :biggrin2: :biggrin2: :dogpile: :hehe: :evillaugh :lol2:
Anyway, yeah....keep on learning new things everyday!

I'm really getting tired of the sluggy 2ltr RB20 when its off boost.

Need a 3ltr...

Lol, every one wants a RB30 nowadays:rolleyes: Personaly I'd rather go for the RB24. RB20 w/ RB25 pistons and head and other assorted bits:licker:
