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.

Jeff.

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 :cool:

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

    • Hey all, not sure how active SAU is anymore but will ask away anyways. Just wanted to get some experience on the 2008 model GTR CBA model.  I've hit that age in my life (43) where I'm like fk it time to get my dream (midlife crisis) car. Looking at importing one in and seeing if these can be reliable if the main flaws are fixed up. Plan is to keep money aside to do the following straight off the bat to future proof it: * install a stage 1 rebuilt trans with all new bits and pieces.  * install a new Bellhousing from the later model GTRs. Or potentially an upgraded stronger version like MAD or ATR. Besides the above two things and typical maintenance items anything else you'd recommend doing.   Been speaking to a few people and the engine on these are very reliable apparently. But keen on the view of the community here. Hoping to find a nice grade 4.5 with low mileage in Grey. I'd go black but swirls too easy. Look forward to your responses and feedback. Cheers    
    • Do Alan and Keith work on Skylines now? I remember buying stuff from them when I owned my Ralliart Lancer a few moons ago. Definitely genuine guys and be excellent if they dealt with the skyline platform as well.
    • Hey all, I'm Gaston from Sydney's West.  I was a member on here when I was a younger lad and owned a mint R33 GTS-T. Ended up selling it and getting married having kids (yadda yadda) we all know how the story goes. Now I'm back with the intention to get my midlife crisis (dream) car ... a R35 GTR.  You'll see me about asking questions and searching the forums. Good to be back and can't wait to get back an Import again.
    • I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.
    • Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust
