I've got a slight feeling theres still the parts from one side in the shed. I'll check next week when I'm back from holidays. I presume you mean the motor and winder assembly?

Still got the drivers one. I'll give that away!!

Using the Dayco 152 tooth belt. Just doesn't seem to line up with the hole centre on either of these dimensions and I guess the belt will end up too tight if the tensioner is in too far
-
Surely the smaller drive pump won't push on far enough due to the collar in front of it. Heres a VLT pump compared with a RB26 pump VLT RB26
-
Just looking at the guide. The dimensions for the top tensioner hole, are they for the hole centre or the side of the stud which is where the markings seem to line up with?

Just wondering if its still possible to fit a narrow drive oil pump once a crank collar is fitted? I have to repair the drive on the crank in the engine I'm building up and we aren't sure what pump will be used yet. Will most likely be a RB20 pump at this stage
-
About to piece together a 25/30 and have the oil pump from the RB20 it is replacing. Would this pump be fine for a set up like this? Was thinking of using the restrictors from the RB20 block also. The engine will have the VCT oil feed hooked up

After a R32 RB25DE head for a 25/30 conversion. Manifolds not necessary PM or sms 0409 958 227

still up for grabs

We did this a few years back with my brothers car and its still working fine to this day. The VL gear is a smaller OD as you can see in the first pics and wouldn't mesh with the gear in the box, hence no speedo signal

Just wondering if the turbo has had the wastegate hole ported and a larger flap fitted? -

Not 100% sure but I'd say you would need to buy a 14mm o ring type fuel rail. The GTR injectors have an 11mm o ring. They may be sold at this stage but I will let you know if things change -
I've got a spare set of 6 flow tested Siemens low impedance 750cc injectors (part no# FI11445) up for grabs. They are to suit a 14mm o ring style fuel rail. 5 of them have done 5hrs dyno time max and the other is brand new still. After $450 for the lot Ph. 0409 958 227 Identical to these

I did actually consider doing that while the sump is off. At least that way I can swap and change bits and pieces

I've put together a new single cam RB30 and fitted an RB25DET oil pump as the VLT pump was worn on the drive flats. I fitted the spring from the VLT pump to the RB25 pump and used the existing RB25 piston. After finding the oil pressure a bit too low I've done a bit of measuring after pulling 3 pumps apart (RB30ET, RB25DET and RB26DETT) and also found a few differences between all the pumps. So I'm now scratching my head with what do do. I know the RB30 pump has around 65psi when the engine is first started (cold) so I'd like to try and keep it as close to that as possible. I presume the RB25 pump will have sky high pressure if I reinstall the stock spring into that as its a much higher pressure spring. In saying that the relief hole in the cylinder where the piston is fitted is 5mm closer to the bottom than the RB30 pump, so the piston doesn't have to travel as far to let pressure out. As you can see from the pictures the piston is also totally different in design to the other pumps even though all 3 measure up identically in size. The threaded section on the actual pump also protrudes further than the other 2 pumps which would have been easily overcome if the relief holes were the same height in the bore. RB30 - 10mm from bottom of the bore, RB25 - 5mm and RB26 - 7mm. I'm after feedback from anyone who has either fitted the RB25 pump as it is and had normal operating pressure for the single cam motor or has fitted different springs, pistons, shims, etc so that the pressure will be spot on. At the moment I'm thinking of running the RB30 spring and piston with a 5mm shim in it which will bring the spring up so it protrudes the same distance from the bore therefore spring pressure will be correct once the retaining bolt is screwed in. But then theres the difference in relief hole height (5mm) so I'm not sure how well that will work as the piston will only move 5mm instead of 10mm to let pressure out. Will this affect my oil pressure much? The design of the piston from the RB25 pump also looks as though it will let pressure out without moving due to the holes and groove in it Heres a few photos of what I've found The RB26 retaining bolt also has a deeper hole inside of it
