Hi guys,

As some of you are aware, i'm in the motion of producing a billet girdle for the rb's. The first one is designed for the 4wd rb30 guys, but i have the capacity to get them made for any rb engine.

What i need to find out is what kind of interest there would be for such an item. There are 2 options, the latter would be the better option, but the first one i have one going in a track car very shortly, so we'll see how that one works.

a) 2 piece billet girdle - The girdle incorporates the sump adapter for the 4wd rb30 conversion. It has a step down to fit to the std cradle (which the main caps are machined to fit)

b) 1 piece billet girdle - The girdle again incorporates the sump adapter for the 4wd rb30 conversion. It is a single unit and replaces the entire std cradle. The bearings are fitted to this new girdle.

The pics below are of the 2 piece option. I'm currently working on the 1 piece girdle, however it wont be ready for some time.

Pricing for these arent cheap, i'll be making 2 parts of stuff all ontop also. 2 piece is around the $2000 mark (including everything needed to bolt it on). 1 piece is around the $3000 mark, pricing for the 1 piece isnt definate yet.

One thought i have had, is to offer the girdle with a machined block/crank to suit. That way eliminating any form of machining error, done in the one place to exact specifications.

I welcome your thoughts and opinions.

cheers

Shane

As someone who's doing the RB30 currently, to be honest, i would say no mainly due to the price but also the fact that AFAIK there's nothing really wrong with the normal one, and plenty of RB30's are doing very well without one :rofl:

It looks stunning though!

cheers for the comments. i thought that would be the case. but someone had to come up with an available one

at what point would you upgrade to one of these?

tbh you prolly wouldnt bother with anything below 750hp and 7500rpm. although any extra block/bottom end strength must be seen as a plus.

as N1GTR said though, there are rb30's out there doing fine, then there are ones that arent

send it OS get the price realistic and i reckon you would sell quite a few. Target price needs to be $999

(it would be nice to see it without the adapter also, for generic use) would the engine need to be lifted to accomodate for extra thickness between sump and block? i know my sump sits within 3-4mm of the xmemeber.

thats a great idea but where in the world would i find a contact for that? if you have any idea i'm willing to talk...

making them without the added adapter is a piece of piss, its just a 2min model change :)

the below pics are of my 26/30 with my 10mm adapter plate (32gtr), as u can see theres about 4mm clearance (sry for pic size, my nets capped :))

      Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i.

      Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.

      Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.

      Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.

      It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
