hey al yeah i bought a new rb25det stock balancer tho i didnt see the point going for an aftermarket version cause i wont be revving it past 7 thou revs anyhow, so will the N1 oil pump fit without modification and do u guys suggest going for an N1 water pump aswell?

[Bliksem]

It will fit but if you're removing the crank fit a crank collar for peace of mind.

Personally I wouldnt bother with the N1 water pump especially if its a street driven car.

Agreed..

N1 oil pump - good

N1 water pump - don't bother for a street car

I remembered seeing something about how to run the VCT/VVT setup with the RB26 head.

When I first saw your post, I could not find it becuase I did not search for NVCS.

Just wondering if anyone has run a Garrett GT3082R with 1.06 A/R non an RB30DET with an ext wastegate? As far as I can tell these should be somewhere in between a 3076 and a GT35R meaning a good trade off between faster spool-up and less boost dropping off in the high end.

After ppl's thoughts on running a 4 inch dump pipe (using a 4-3.5 reducer at the turbo) reduced to 3.5" later for a GT3582R on a 25/30, is it worth the effort?

Not bad at all! Does it clear the bonnet tho? Looks like it would be might close near the camgear cover.

[dano4127]

yeh i think it is close but dose not touch!

It has come down to piston choice time. I am currently looking at the arias 9.2:1 and 9.5:1 CR pistons and i am trying to decide which set of pistons to go for. Aiming for around 350-370RWKW (mainly street use occasional track use) using a GT35R turbo. Which compression ratio would best suit my application?

Looks like a weapon mate, id be interested to see how your boost responce goes as ive heard some very mixed stories re plumbing it off the housing, some are great, others very average.

Engine looks like a weapon though!

[Spoolup]

Go the CP 9.0:1, the Arias might be a tad high for the power you are aiming for on pump fuel.

I second that.

I'm using the arias 9.2 comp pistons, after cc'ing the head, the bowls were smaller than standard (the head had been faced more than once before it was in my hands).

With a std thickness head gasket comp would be close to 9.4 so I've got to stuff around finding a thicker head gasket to get it down to 9.0ish.

I only intend using 1 bar on pump fuel and winding it up on race fuel.

While on the topic, what brand is the best bang for $ race fuel?

Anyone got any good videos of they rb30dets ?

well my head is away getting rebuilt rang the guy up and he said that there isnt much wrong with the head so that all good and my stuff is away getting balanced, engine is about 40 percent complete just waiting to get my stuff back then we can build it up so far just spent over 7 grand with about 9 or 10 grand to go the only thing i wont be touching is the head besides the rebuild cant wait to get it going it will be exciting

[r_speedfreak_r]

hey maddo. Are you getting the head port n polished? I personally think its well worth it

[Maddo]

yeah i will get the head port and polished but other than that the head will be stock hoping to achieve 300rwkw with my set up
