1 & 2 Piece Billet Girdles - Is There Any Interest?

[shanef]

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

i take that as a no lol

why the huge price?

[shanef]

a) machine time

b) cost of material

the prototypes alone cost me in excess of $5000

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

It looks stunning though!

at what point would you upgrade to one of these?

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

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

Thats a secksi piece of billet ally

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 )

Finally got some pics of the girdle installed in the engine
