What I did this weekend since I wasnt at Vivid working:

I rebuilt my "drop in piston" motor. I didnt do the rings right last time so they didnt seal right (too tight) as you can see in the first few pics.

Head... no bent valves!!!



Some carbon build up





Seems as if the top ring didnt seal well





Do a slight hone,





Cleaning, take the pistons to the polishing wheel to make them silky and smooth





Checking end gap and filing




New valve seals


Assembly...




It took a total of 19 hours. Taking time making sure it was done right. Will see after break in how it does. It was a long/but fun weekend. VIVID RACING can supply you all the parts necessary for a build like this. We can also provide first hand experience for install questions
This is a great "cheaper" alternitive to a full tilt motor build. A build like this should hold 600 whp with no problem.

Thanks for looking!

nice job Evan!! great pics and insight to what goes on inside a "drop in piston" engine. perhaps you could show what pistons, rods, rings you used and maybe some MSRP on the parts total including gaskets and such...??

 

Ill work on getting prices together...

Arias pistons 85mm and rings
Eagle Rods
Oem Head gasket
Cosworth rod bearings
Arp head studs

Evan, did the drop-in pistons change your compression ratio?

 

Nice!! What pistons did you have in there before Evan?

 

Yes sir a little lower 8.5:1 (Better for high boost)

 

I used the pistons that came out of the motor. Arias... I took them out to see little to no scuffing on the side wall, so I had a good idea that my piston to wall clearance was ok. I cleaned the carbon off the top, then polished the pistons. After they sat in soapy water for 30 min I scrubed and rinsed them. Good as new
