RB25DET Modifications

[Guest Nismo_Freak]

Here are my plans:

- 3.5" Downpipe to a 3" Test Pipe and a 3" Blitz NUR Spec R Exhaust.

- Greddy Profec B Boost Controller

- HKS Turbo Timer

- Boost/EGT/(Air/Fuel) Gauges

- Twin Electric T-Fal Fans

- Skyline R33 GTs-T Radiator

- Apex S-AFC

- Blitz FMIC w/ custom piping

- Homemaid K&N-Filtered Cold-Air Induction

- 12 psi Boost

Take a look at those plans and lemme know what you guys think... suggestions are very welcome, especially ones that make things a tad cheaper!

Now a few questions:

1.) How much power does the stock GTs-T clutch hold?

2.) How much power do you think I will make out of this system?

3.) Think it will be reliable?

If you are going to go a 3.5" dump pipe you should go 3.5" the whole way, other wise the bigger dump won't make much difference.

The stock clutches aren't that crash hot. Mine really started to slip when it hit about the 180rwkw mark, when I was giving it a hard time.

How much to the clutches cost down there for the RB25? No one in America sells them unless I go through a Japanese company or import myself one.

[Guest MFX_R33]

I have just go a very nice 6 puck item installed in mine. It shudders a little off the start but is nowhere near as agressive as a brass button etc, and it is reputed to be good for about 250rwkw. The clutch itself was about $700 supplied (so about US$350).

That is a very big relief... no $700 US clutch from Japan, thanks!

Exhaust: ditch the name brand muffler and buy something local thats of straight through design.

Boost controller: a decent bleed setup will hold 12psi ok. Mine does.

Turbo timer: use yourself. ie hang around for a couple of minutes after a hard kane

Radiator fan: standard clutch fan won't fit in engine bay?

Can't comment on power output, what with the different dynos you guys use and everythng. Will be very quick in a s14 tho.

manual bleeds sux! EBC hold boost 100 times better than manual!

when i got my car on the dyno last week with the turbosmart bleed it from the printout it varys boost all through the rev range!

EBC all the way!

Well, I said decent bleed setup - turbosmart is not this. I'm using a Norgen pressure regulator setup in recirculating cycle, works fine. May not be perfect, but suits my needs. Remeber, Nismo_Freak is looking for ways to minimize costs and a bleed setup excels in the value for money stakes.

whats that pressure regulator off?

bleed valve is good for starter, but u cant beat a ebc for tuneability later on

[Guest Nismo_Freak]

I dont trust bleed valves... sorry.
