Started my discussion here:
Deciding which parts to buy for my rebuild
The car is still a daily driver that was originally being built within the confines of SP rules for AutoX, now I'm doing whatever I want since I'll be in SM2.
Current list of power mods:
-Complete FM Intake and Intercooler
Current build items purchased:
-Wiseco forged turbo pistons (9:1) (+1mm)
-Carrillo Super A rods
-949 Twin Disc Race Clutch
-ARP Head and Main Studs
-Supertech Valve Seals
-M-Tuned Coolant Reroute
-Might add Boundary Oil Pump Gears/Pump to the list
After much browsing and a little posting, I decided to do a build thread to post the findings and questions along the way.
Here are some of the photos from the tear down:
Cylinder 2 Marks: Piston Slap?? All of the cylinders looked like this to some extent.
.001-.002 Scratch in Cylinder 3
This mark pretty much honed out. Then I had I had it bored out for good measure
And this is what lazy amateur tuning looks like.
First thing i did today was to put the MSM piston/rod combo on a scale to find out what they weigh. 932 and 921 grams. This includes the piston, pin, clip, rod, rod cap, no cap bolts. They were marginally dirty with some clean up fluid on them. I was weighing them to get a general number. I'd imagine those cap bolts would drive that number up to around 960 or so. I'll probably weigh the bolts when I go back.
The FM page claimed a weight for the Super Rods of 417. I only measured one but it was 427 and FM claims that with the Wiseco's and Super A's its almost 0.25lb per cylinder. I can confirm this is pretty close. Probably somewhere around 0.1875-0.22 . Now the new parts weren't assembled but they measured about 880 once added up.
The difference between the stock MSM clutch assembly and 949 assembly is about 18 pounds using a bathroom scale.
For those in the Tulsa area I'm using Moritz Machine Shop. So far, fair pricing and great customer service. They recommended Clevite P series race bearings and use them in all their motors from twin-turbo monsters to NA screamers. Sounds like they do mainly V8's but I know they are familiar with the Miata.
