Only in the fact that it has to physically pump more oil around (extra oil in the lines etc) Personally I doubt an oil filter relocation kit would have enough effect to actually starve the head.

Just thought I would bump this 20 year old thread because the Skid Factory have just posted up a video summarising a lot of the content, format might be more familiar for newer members

fyi guys, Well yesturday i picked up a RB30 for my conversion into my R33. I will be using my RB25DET head on the RB30 block. So i started stripping the motor down, pulled the crank, pistons, girdle

wont affect anything. We use a truck oil filter thats about four times the size of the std skyline one and its got about 1m of line to it and then it goes to two oil coolers and back to the motor.

also what sump would i have to use to run in a s15?

That would depend on where you have the motor sit in the bay, best to install the motor without the sump, fabricate the mounts to suit, then see clearances to the cross member and sway bar etc

or have a chat to Fatz regarding what they did in his S13

I haven't used SolidWorks as such, but I used to work for an automotive R&D company and there I used SolidEdge - pretty much just a leaner version of SW :) At the moment I use microstation to do all my drawings whether they be .dwg or .dgn.

Waiting for my N1 oil pump and bearings to arrive then my RB30 will be running again.. after xmas will probably see a GT35R get bolted on :huh:

I'm just about to get the cams sorted from Tighe cams for mysetup.

I've been recommended by both my tuner and Tighe cams to go the 265/265 in/exh.

My only small concern is will the 265/265's lope over noticeably on idle? A mate has the 254/254 cams and the idle is baby smooth; the note did change slightly but there is no lope.

If the 265/265's do lope would the 254/265 setup smooth the idle?

I wouldn't mind a slight lope but I've been you tubing SR20's (same bore stroke) with 264 cams and they lope over like bridgy's. :S

All though the SR's do run a LOT more lift that I will be running (8.9mm).

The cams are hydraulic so no doubt slightly reduced ramp rate which may also smooth idle slightly compared to rb26 solid cams.

Any guesstimates based on sort of similiar experience? :S

Considering the cams you are running at the moment, either setup will be a vast improvement. Being that you aren't running a huge turbo, the power difference of the 264 inlet cam over the 254, i wouldnt expect to see an extra 20rwkw between the two. Its all up to you, but considering you are almost at the limit of streetable 2wd power, i would go the smaller inlet, to maintain the low rpm torque, and idle quality, but its all trial and error.

Cheers Adriano,

I do plan on dropping a GT35r .8 on it at a later date once I push the limit of the GT30.

As Uni is now all done with and I'm working I have a fair bit more $$ to throw at the car and have some fun with it down at Mallala. So it will be primarily a car I race down at the track. Similar to the Troymeister but I'd still like it to idle 'ok' so it doesn't attract too much attention. :(

I'm hoping some one has played with 265 cams in a hydraulic head and the RB30. ;)

this vid is of a 33 gtst i've help built this year. its a built rb25, solid lifter head, 260/9.15 cams, big port work both sides, os valves on the exhaust side. its just sounds pure porn at ilde (~900rpm), and u should hear it on full noise ;) *creams pants*

Sounds very very nice. I've replayed it over and over and over. I could listen to it all day. lol.

All though partially due to the solid lifter setup. Hydraulic cams sound much smoother. :) A good thing for not being defected though. ;)

Cheers Shane. :(

i know myself and the owner dont get sick of it hahaha

they can be turned so its not as 'raspy' on idle, but then there goes hp, and who wants to do that? :(

he's running a 35r with the .82 rear, and power tips over at 8000rpm (although 1 silicon joiner is sucking closed at high rpm so that could be playing a part in that) so i reckon something closer to 270deg would be ideal on an rb30 with the 35r

How many ponies did it produce?

You could try sourcing a set of A'PEXi 270 degree cams, pretty sure these retain the hydraulic lifter setup... from memory they run 9.0mm lift.

The downside is they went out of production some time ago so Yahoo auctions may be the best bet...

      No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.

      R34 GT > GTT compatibilities

      By Kinkstaah · Posted

      Ye, in terms of bolting up the "Conversion" from a GT to a GTT is effectively "Use GTT parts for everything" Except the subframe itself, because you won't want a HICAS/4WS subframe. Remember your ABS system will be different too, thanks to GT being the S15 3 sensor system, instead of the R34 4 sensor system for wheel speed. I do not know how people get this to work given R34 diffs do not have a provision for an ABS sensor (they are on the tone wheels of the axles). I assume***** people use S15 gear/R34NA forever when they realize this - Or they convert it to a rear diff/axles that are R33 style which I presume has the singular speed sensor on the diff itself, but then you have to wire it all in and...and... and...

      Rear hub bolt torque r34

      By GTSBoy · Posted

      The ones in brackets are the first stages of tightening. I usually aim for the middle of the range. They give a range because it's actually not that critical to hit exactly the right bolt tension. Enough is enough, and too much is too much, and the range given is inside that range. Half of the bolts in the suspension are problematic for putting a torque wrench on anyway, so just get done up to mechanic tight  and spanner checked a week later.
