Got Over 400kw Atw?

[Marko R1]

Thanks that would be great!

I'd be keen to hear more about lowering the engine. I know several RB30's have been put in at stockish heights, but everyone seems to do it differently. There's a market for bolt in mount kits, so everything needed to install RB30 to R32GTR in one package.

that guy simon has the worlds best kept secret on lowering the engine but he won't let the cat out of the bag

.I have 1 theory which I've discussed with another mechanic and would work

[r33_racer]

I heard of a trick using rb20 engine mounts which lowers it 10-15mm. Though dont know how accurate that is as I havent done it myself.

How much lower would the engine need to sit in order for the timing cover to not hit the bonnet bracing? Would 20mm drop be enough?

[jangles]

ultimately its the sump that inhibits most from being lowered too much, get a 26/30 specific one and drop away.

I recently did a 26/30 for someone. It required an 8mm drop, bonnet support cut out towards the front and the twin turbo 'badge' shaved off the twin turbo pipe to make it smooth.

With all that, it only just touches by a whisper.

With a standard bonnet I'd say 25mm would see it clear with no other changes.

I'm fairly sure RB20 mounts are the same height as GTR but I could be wrong. The other problem with lowering the engine in the subframe is the clearance between the sump and the subframe is only about 15mm at best from factory. You could possibly go 10mm of that but I reckon driveshaft clearances would have to be considered if you did

Then there's the easy way.......

Drop engine in on standard mounts

Call Blits Bodykits - custom bonnet ~ $1500 that's ADR approved.....

Something that is seriously lacking in this thread!

exactly what i did to mine - cut the bonnet brace above the front cams, took off the twin turbo badge & milled off the boss for the badge.

funnily though, i had to run the bonnet without the insulation as this was starting to rub the paint off my newly painted covers. that is how tight it was under there!

[Nee-san]

This just tells you that the good son of rajab didn't intend for an RB30 to fit in there.

[Marko R1]

Yes and after doing my own conversion from the garage, I would never do this conversion to a well respected or iconic r32

Quoted $1500 + my sump to get 8 ltr racepace one what u guys think? Trust weld on? Lolol

[R31Nismoid]

High Octane is more expensive (as a comparison).

Given you are spending a small fortune on your motor, whats another $400 for a proven piece of equipment?

[NYTSKY]

Contact ASR, they are in Vic. Under $1300 for their race sump.

For a bucket that has crap ground clearance with no internal baffling (IIRC). No thanks.

I was thinking if you could achieve say half inch of lowering engine towards sub frame via engine mount mods and then lowering sub frame half inch off chassis rail then you would be pretty damn close and both of those things are very straight forward and have probably been done before. But as you said you would need to look at drive shaft clearances and angles.

[Marko R1]

Talk to rob at rips racing. The sump he did for me was a piece of art and proven on his 7sec 240z. Not the cheap the ultimate IMO.

I have about 30 pics of my sump before I fitted it but cannot share them

[OMGGTR]

Lol i think ill stick to racepace ash can u get them to do any cheeper or u dislike me to much

[R31Nismoid]

If you buy 5, you might get a discount

[Marko R1]

Lol OK

[Marko R1]

this is true
