Up to 2.5k max i reckon..

what you getting done?

or buying a new motor?

only 2.5? hRMmmm fair enough

under the process of doing a rb30 bottom end rebuild with a GT30 turbo. being left with a rb25 bottom end (which is useless) im opting to do a rb26 top end.

leaving a full rb25 motor to sell.

low k's, good condition. complete with stock turbo. 3k. normal 25's go for about 2.5k if you buy from a shop. private sales can have some good bargains but you arn't sure what you will be getting!

i looked deeply in to the 30 bottom end also. final decision for me was if you want a RB30DET/ DETT. save up and buy one made for the full rev range of the head.

Personally id go with a stroker kit, and while you have the engine open do whatever else you can afford to the internals.

A stroker kit for the rb30?

    • Nah, you failed to pay your washer cover subscription and BMW have revoked your access.
    • Haha thanks Lith,  So it's currently working quite well and the torque reduction is setup and working phenomenal. It also got a custom torque convertor from All Fast in WA. Stall speed somewhere around 5500rpm unlocked but still with the lockup. The car went back onto the dyno after a 3yr hiatus (even with the dbw, and other mods completed in this time) managed to make ~515kw at all 4 hubs. Sean setup the Torque reduction which now sounds awesome and working well. We setup adjustable torque controlled launch control aswell.  Man what a feature. Especially when drag racing on street tyres I Managed to get out to the drags late last year and tick a huge bucket list item off of running mine and the cars first 9. Car went a 9.98 @142 Still had the young fellas car seat in the back aswell.  This was on 255/40/17 Nankang AR-1.  Currently the Turbolamik is still completing it's own torque calcs and managing shift times from there. Unfortunately emtrons can export is still a little restrictive to export the ecu calculated torque just yet but I have recently been suggested a work around that I just haven't had a chance to trial yet.     
    • Yeah its bad eh. Ey! Watch your mouth. Yep, spot on. The rear's are always gone too though from brake checking. I had them perilously close to a tree that we had taken down. I think the tree peeps may have taken it. Either for a trophy, or accidentally.  
    • f**kin' yikes! That insulation is the shittest stuff I have ever seen. You need to do an insurance job on that f**ker, pronto. WRT to the washer cover, I would have said that there'd have to be some at a wrecker, then remembered that it's a BMW, and reasoned that every single wrecked one would have been tailgating and so the front end would be trashed.
