Recently bought a 180sx with a Rb30det in it.

Just getting some work done to it now.

I think i really need to be changing the inlet manifold as its currently got a standard manifold thats been welded up (not too rugged) to be front facing. It doesnt look like it would have good flow to number1 cyl though.

Its got an r32 Rb25de head on it.

I need to know what manifolds will fit this head. My tuner thinks it might be the same as an rb20det because it is a small port head.

Thoughts on the greedy style manifolds?

Need help quick.

Just bumping this up. SirRacer, Are the stud holes the the rb20det the same? I can grind the ports out to match the bigger ports on the head no worries.

The custom plenums look cool, what else needs modifying to make them fit besides intake piping? Looks like they use standard intake runners so fuel rail shouldnt be a problem?

Are they for the r32 rb25de head? Wouldnt mind seeing some prices

I just need this intake manifold before i can chuck it back on the dyno.

so far, getting 180kw at wheels at 4000rpm before boost spikes and goes wild (because of wastegate) which has now been sorted. So the manifold is next on the list

      What brakes on R34 GTT(Europe)

      By Kinkstaah · Posted

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      What brakes on R34 GTT(Europe)

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
