Im just about to fit my 26/30 in the engine bay of my R33 GTST. The steel engine mount brackets i got with the block doesnt line up with the RB25 rubber mounts in the bay though :S

I feel really stupid here but anyway, it seems like the angle of the brackets is a bit to much and they just seem like they should sit closer further ack on the block :thumbsup:

Also if someone got pics of their mounts i would be glad!

Use matching brackets and mounts..

It sounds like you have RB30 mounts on the block and 33gtst brackets in the engine bay.. IIRC the RB30 mounts sit the engine slightly further back than the 32/33gtst mounts.

Thanks for your help! Ye i was really fussed about what brackets to use with what mounts ;)

TiTAN> I can see you have a R33 GTS-30T in your info, so you say that i can/should use the factory R33 GTST engine bracketes and mounts?

Might have solved the problem! Im using universal rubber mounts with an offset of the bolts of about 40mm, bolted straight in. Might make a spacer for the LHS engine bracket since the engine is leaning a bit and he bolt and bolthole doesnt flat out :spank:

Anyways, the engine is in place and i can start with the exhaust manifolds!! Yeeeaaay :D

BTW, the rubber mounts costs 10 AUD/piece :)

I know I'm pulling out an old thread but I'm doing the same. 

A rb26/30 into R33 S2. 

And was told that i need custom mounts as the rb30/26 is taller then a Rb26dett or Rb25det to it fouls the bonnet. 

 

Is this true or not. 

 

Cheers.

      Pops when backing off throttle, rough-ish sound through rev range.

      Hence why I suggested some tests.

      Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
