2. Replace original standard 127,000km clutch (with the same thing??).
3. Replace original 9 year old radiator.
4. Get some proper gauges.
5. MS2
6. Eagle rods
.

7. Old BP block, checked for cracks and straightness, line bored, decked, bored and honed as required
8. BP crankshaft, crack tested, plus ACL mains, big ends and thrust washers
9. Gasket and seal set
10. Pistons and ring set
11. Engine balance
12. I'd replace oil pump as a precaution
13. Sump and baffles?
14. Even if head is OK there'll probably be a damaged valve or two
15. Head shave to clean up the odd bit of mess made by loose metal
16. ACL Head studs
17. Timing belt kit if it was getting towards replacement time
18. Do you have a coolant re-route yet?
19. If replacing any valves then get the ports tidied up a bit
20. Anything else damaged in the area of the exit wounds

Forget the big turbo and spend it on more seat time. It's more fun.

Or you could save all the hassles and buy an NC.

Dave, a couple of things you didn't mention.
Air temperature in the shade was mid 30's. It was a HOT day!!!!

Dave,

Just send your engine to Wozzah1975. He can arrange transport fairly cheaply.
Don't get stressed about individual engine parts/cams/rods/pistons ect. It will drive you nuts. Let him build you a motor that is bulletproof and will handle 250rwkw. He will use only the good stuff internally and you don't need to know all the details regarding cranks/balancing/bore size/oil pump shims/Arp main bolts ect ect. That will drive you even more nuts.
Accept it will cost you at least 6K and unless you are about to rebuild it yourself, there is no way around this.
Get it put back in with a Exedy Sports Tuff or 949 clutch.

Then the fun begins to get it tuned right. I cant help you with that, but at least you have a engine that can handle the punishment you will give it.

Daniel Deckers did mine and I couldn't be happier and he can do yours as well, but Warren is much closer and he has a wealth expertise in these motors.

Excellent work though to last 120,000km before detonation.

My 2 cents for what its worth.

Richard.

x2, Richard. I gave him the first list of bits and machining to let him think about it for a few days then I was going to tell him exactly what you said. Unless Dave's an experienced engine builder then Wozzah's the man.

+1 for warren. When did my head upgrade I dealt with quite a few suppliers. Warren, Bill at Miata roadster and SQ engineering were the stand outs.

Yup, with hindsight, getting so much out of a standard bottom end for so long was a decent result. Just wish it had exploded further into the weekend than the second bend of the second lap on day 1 of 2.

Nope, no engine building expertise.

Yup, will seek out the right rebuilder along with using all the very helpful advice on here. Keep the ideas coming please.

$5k landed in Melbourne including extra $700 core charge. They'll add further products for little or no extra shipping charge.

Opinions?

What have your local prices been like. There have been some problems with the boundary oil pumps. An external regulator seems to be a better way to go.

Motorsport Essentials have 'BP Performance engines' from $2800.
Located in Mulgrave, Vic so a lot closer than California !!

Several members from Vic Mx5 club run their engines...

Another option to consider.
