PetenAli's WBX 2500 engine build

[bikermike87]

When its all run in Mike we'll have to meet somewhere halfwayish between us for a weekend and compare notes. Can't wait to see your Westy which looks great in the pics.

Yes, we should, that would be great.

Things are progressing well and all that is holding us up is me finding the necessary ancilliaries. Two key bits are the bolt and washer for a three groove crank pulley - PNs N90261901 & 11105259 if anyone can help please PM me.

Also a pair of really clean inlet manifolds would be good. I've found a pair that haven't got pin holes in them but they are a bit scruffy.

Thanks very much. Like Ian says, "Don't want to use up all the slack"!!

Replied to your Wanted ad Pete. Bit more news later

Coolant transfer pipes needed a good tweak to get lined up:



Thankfully they are pretty soft:

Spot the cheeky oil cooler plumbing mod...

that is pants, and would be a pain to allign insitu in the engine bay

I had to search around a bit to find a good-fitting length of pipe too.
Dont know who is the manufacturer.

Not cheap either!!

the stainless pipe behind pulley I fitted (from Brickwerks) hit the pulley, had to take a hammer to it.

Gentlemen, a great read and thread this and my reason for registering for my first post, the right person in silverbullet, as an engineer, was needed to carry the historic 2.5 OKRASA onward and upward (forward), I imported a kit from Germany way back in 1986 and assembled it into a 1.9 pre 'B' case for turbocharged use in Rallycross and fitted in a VW Beetle, unfortunately, the 90's recession and a change in Motorsport direction meant it sat unused for 26 years, but Cutting to the quick, it's now out doing what it does best and worrying 911's on race tracks all be it somewhat de tuned, and minus it's turbo, in short, it's reliable, at least for a racing motor, quite a revelation after racing air cooled engines. One thing I can throw in as regards building these motors is to watch out for the barrel spigot sealing shoulder fouling on the shouldered case nuts, the result won't need description, but I guess it depends purely on bad luck, as I find the shoulders on the nuts vary, and trust me not to notice one odd ball had the un desired effect.
Another thing I do when fitting the remaining piston pin circlips, is to dilibertly miss fit it into the wrist pin bore and then push it into position, I use a suitabley sized alloy drift, the idea is to 'hear' it click positively into place, I think you can guess why I do this,,,, let's just say it works and you KNOW the clip is in the groove.. Don't ask...
So again, congrats on reviving these historic motors, and as ever, the Brits tech and engineering nous saves the day.
My own 2.5 is constantly evolving, just now having a valve job and some more valve lift introduced via new rockers.
Best regards, John.

Thanks for the vote of confidence and welcome aboard

Interesting from Johnnyace (welcome to 8090 by the way). I have a little nagging thought about a 2.1 DJ in my Classic Trials Beetle. It goes pretty well with a tuned 1285cc so a 2.1 that can take a Syncro up Simms and Blue Hills would be an interesting concept.

Totally agree with your comments about silverbullet as well.

As you're back Ian, I need to agree with you a final list of all the bits needed to finish the 2.5. Like you say - don't want to lose the slack and March will be here before we know it!

Leaving nothing to chance, the pulley is a really snug fit on the crank too, which always helps!

So close I can almost taste it


PS I fitted the plenum off the Oetti* Pete, it has more paint on it than your one and the all-important bracket for the fuel pressure regulator...

*I have other plans for that

Proper syncro-spec pulley seal too!

It's good to hear some more progress on this, after doing the Clee Hills trial last weekend I'm having nagging thoughts about a Holman 2.5 for the buggy, time to look out for a rebuildable DJ though anyway

New machine running itself means I can do other things
This is what a Friday afternoon should be like: OEM fuel lines and final dressing before it gets test run...

...and then I didn't have any good shims the correct thickness.
BW order already placed.
