Can someone with an RB30DET in their R32 GTSt, please measure from the exhaust cam cover to the strut tower and tell me what they get?

Cheers!

~200 mm with RB26 head and cam covers.

That's with the engine lowered ~15 mm on the engine mounts

Thanks for that, I measured 205mm on my mates GTS4 with RB25/30 and 190mm on my GTSt with RB25/30..

Have put brand new engine mounts in along with a known matching set of RB20/R32 brackets (originally had an RB30 bracket on the passenger side) but still trying to figure out where the missing 10-15mm has gone.. will be trying a new engine crossmember on the weekend just incase mine is bent or isn't actually an RB20/R32 crossmember.

Having problems with turbo hitting strut tower but even if I get that 10-15mm back I still need to gain another 15mm or so from somewhere :P

P.S. Nice slotting on the stock engine mount brackets, didn't think of that when I was having bonnet clearance issues!

If the turbo is hitting the strut tower it must be fair tilted over.

I dropped mine 13 and 14mm. However since its settled over the years (fitted new engine mounts) it does appear to be sitting a tad lower.

If I jack up the car the sway bar slightly kisses the sump.

CAn you slot the drivers side more to give oyu more room?

That's exactly what I did :bunny:

Had 3x R32's in the workshop (my gtst, another gtst and a gts4), after taking sevearl critical dimensions, my car isn't bent so got pissed off and redrilled the holes on the drivers side 15mm lower :)

The engine mounts have tabs as well as studs. If you install them in the wrong side, the tab stops the stud dropping down the slot in the subframe and that raises the engine. Maybe you just have the RHS engine mount around the wrong way and that is kicking up that side of the engine. You can see the slots, tabs and studs from underneath, so it's easy to check.

Correct mounts on the correct sides with the correct brackets and everything is seated properly, spent many, many hours making sure :P

not sure what brackets you have now but it's important to note that the RB30 brackets sit the motor back about ~5-10mm compared to the rb20 brackets. can help allot with bonet fouling issues but if you matched up an rb30 exhaust side bracket and a rb20 bracket on the intake side then your engine could be sitting potentially horizontally twisted (depending how much give are in your mounts) with the front facing your L/H headlight. plus if your going to buy a new crossmember you could just get a ceffy member which sits it further back again.

if you wanted to change everything then go for the 33 turbo x member and brackets with rb20/30 mounts. probably not that much off an issue to do that though. mine is in a silvia and it is a problem with them!

    • Anyone used A to Z Imports in Goldcoast?  I was referred to them for engineering and RWC? However besides a few one off bad google reviews it all seems pretty legit?   https://www.atozimports.com.au/
    • RB26 JE pistons to suit 2.8 stroker crank 77.7mm and 86.5mm bore Custom made with EN plating and Je perfect skirt.  Valve pockets Suits 1mm over valves biggest lift you can throw at them. 21mm 210” wall 9310 upgraded wrist pins to suit standard sized 121.5mm rods. I had these made for my build but block had to be rebored to a larger size so sadly I can no longer use them. I spent a-lot of time and money on these pistons.  See photos these are the Heavy duty forging in 2618 material with all the bells and whistles accumulator grooves double force fed pin oilers skirt milling window milling etc.  The En plating was done to the whole piston this helps with heat and also critically in the ring grooves to prevent ring micro welding. The Perfect skirt is JE's propriety coating its a permanent coating that expands and contracts with the bore to prevent piston slap and noise and also friction. you can look these features up.  They have been balanced to a tenth of a gram at my expense. They come with Gas nitrided ring pack's and oil ring rail supports all brand new never used. The Dome volume is 17.9 cc which based on your Gasket thickness and chamber volume can put you anywhere you like in terms of Comp ratio in my case it was just under 9:1 but this is highly customizable for your build.  In terms of sizing these pistons will work with any 77.7mm build using the normal sized rods.  I did buy an extra set of rings at the time of purchase incase i stuffed one up during gapping so i will throw these in at my expense. I purchased these through performance wholesale in Brisbane and still have the receipt if you were to make these now it would cost more then double what i have them listed for. I am super fussy when it comes to building motors so you will see they have been measured and numbered with marker in the photos. Every thing has been handled and stored with the utmost care and diligence. looking for 2350 ONO any question please ask. test is better 0450 428 895 they will be sent via registered post anywhere in Aus free international buyers contact for quote.  
    • Ok that makes sense, I was circling around the idea that this kind of wear would only occur with too long intervals between oil changes but I see what you're saying about the cause being something else.
    • That's perhaps not even correct in this instance though. If the OP were in fact to bin all that troublesome crap and convert to DBW, and then if the problem persisted, we would at least know that it was not caused by any of that troublesome crap and he could go looking for it in more likely places. AND... he would have a significant upgrade in niceness to go along with it!
    • What has an oil change got to do with whether wear is occurring or not? Wear may be facilitated by oil having been left in too long and broken down - but it is far more likely to be a mechanical issue (ie, pressure). The thing with the tested oil being only 5000kms old makes it perhaps equally likely to be lead from bearings or lead from the additive.
