R33 Rb30 Conversion

[the phantom]

Bl4ck32....why did you go with a custom 1 piece tailshaft?

Cubes et al....is there actually that much meat on the '32 engine mounts that you can slot them 13/15 mm? On the R33 the mounts are minimalist alloy items and that much would almost cut through. Since my entire front end is now on a pallet on the floor I may take some pictures and measurements of my setup...

Joel:

In your PDF its says that u changed the 25 idler pulley to a tensioner pulley.

Were these 30 or 25 items?.

My 25 pulleys are rooted, I can get 2 x 30 tensioners (I asked for VL RB30E ones) for cheaper than 25 ones, also how much did u get ur Gates 94407 timing belt for?

cheers.

hi guys great work.

quick question have any of you done cams when fitting the rb25de head from the r32 if so which cams rb26 or rb 20 or custom

thanks. my next project is n/a using one of these motors possibly an rb25/30 variant.

I've got a question, when you guys have relocated the tensioners, have you tapped the spike/bolt for the spring to push/spring on, to get the self tensioning effect, or have you just adjusted them by hand and tightened them, if you know what i mean....

I'd like to know too.

The RB30E tensioner pulley has a second stud to stop the spring from spinning around, I havent seen anyone use the second stud in a RB30/25/26

Adjusted mine by hand, no springs used.

I'd assume all threads were covered in Loctite?

Yeah, i will also run a medium strength loctite for sure, just for safety.

This is from memory.. (again) lol

The drivers side is basically a piece of sheet metal shaped in to an engine mount. That was redrilled with no issues, old holes then filled in and hit it with the grinder.

The passenger side engine mount had the flat plate bit that bolts on to the engine ground off then rewelded (much better I might add) lower.

The tensioners are all the same, RB30/20/25/26.

I bought a new RB20DET item which used 2 internal bearings next to each other.

I then ordered a RB30 item as they had them in stock and found they only use one bearing. lol Typical holden.

I didn't bother with the spring as the tensioners are locking tensioners and require roughly 20kg's of tension on the belt.

The spring doesn't tension the belt correctly, it pulls up the slack to make life easier when fitting.

The belt.. $37.50.

Ok cool. So im going to mod my RB30E mounts by redrilling.

15mm Drivers side, 13mm Passanger.

*fingers crossed*

Let me double check the measurements Ben.

Thanks mate. Was hoping to do the welding this weekend when I get my gearbox welded up.

Bl4ck32....why did you go with a custom 1 piece tailshaft?

r33 gearbox (with custom gearbox x member to bolt it into a r32), tailshaft, and modified speedo sender came out of another r32. Also had the r33 yoke etc. So it was a bolt in upgrade from that point.

It weighs heaps less too. I dont know how that would affect performance though ....or....lack of

Ben,

Stupid me.. I didn't write it down anywhere.

It may be on my oldies computer as that is where I dropped the motor in.

Failing that I will give Shaun a buzz as he knows

Oh great! lol..

Well I am probably going to do it tomorrow.. so if your around.. please try and get the info!

the belt.. $37.50.

Cheers for that, I've been quoted the same price.

A question for everyone.

How often would you change the timiing belt? would it need to be changed more often if it was making 350-400rwkw and up?

[Bl4cK32]

I just like the idea of not having to worry about a worn belt letting go, or a tensioner bearing bolt snapping to blow my motor. I reckon around 80,000 is a good time...hell why not 50,000 kms when the two tensioners + belt comes to $220 for a major service..

[Cubes]

Darren can you remeber what the motor was dropped by?

I did post it some where.. I think it may have been in this thread.

[GTR-Ben]

Please?

read back a couple of pgs...I forgets too
