Hey guys!

Was curious to know, as i'm about to start on my rb25/30 build what things will i be needing to know and was there any headaches i can avoid? Anything that will be needing to be custom made or anything i will need to plug or create into the engine block?

Any infomation on this build will be appreciated.

Thanks guys!

Use the later block with the water and oil outlets on the hot side, they also have a flat tensioner area in the front.

Earlier ones have the oil and water outlets cast on the block but not drilled and tapped to take fittings, some also dont have a flat tensioner area on the front where the water pump is.

Block is 38mm taller so expect to extend your piping.

There is a well written detailed write up on it, study it.... http://stevenwelsh.site.net.au/RB30_DOHC.pdf

    • Nah no bearings, just slip fit.  Would be a reasonably challenging but not impossible job to modify it to run bearings but I'm hoping that's not necessary as I may have well built one myself if I end up spending hours modifying it!
    • Brumbys with good shells are bloody expensive, I've looked at 2 "cheaper" cars, and walked away from both,  plus after some research spare parts are fairly sparce I'm starting to think that I missed the boat on finding a clean one that is straight (ish) and without alot rust I'm starting to think about a old Hilux as panels and other parts are much more available as they sold tens of thousands of them I use to be indecisive but now I'm not sure
    • A Brumby would probably fit a big metal toolbox in the back... this is how it begins  
    • Picked up a new OEM boot seal for the MX5 today as the old one got ripped a bit by me being a idiot by seeing if I could fit a large metal tool box in it, it didn't fit, and ripped the seal with the corner of the tool box I am still waiting on time to get the cams and new balancer installed, as well as the repairs to the boot Time will not be an issue soon though
    • I was more thinking so it doesn't flop around as much rather than for rotating it. Once you have the balance right, it should rotate well enough, depending on how much resistance there is on the pivot. I think you said the pivot point was on a bearing though didn't you?
