Thread: Operation SR24VVL IN PROGRESS ONCE AGAIN

Machine the Pistons and you are set with any head gasket....

I have heard that there are motors out there running 92mm with a std vet gasket machined out to fit the 92mm bore and there holding well... so there must be enough room between to seal. Also ther has to be enough room for it to seal, because everytime I've used a NEW mazworx gasket they have had zero issues.. if there was not sufficient room for a seal how could this be the case. I'm just saying its definately possible. Maybe they just don't feel comfortable going that close.. idk.

yep, thats what he's doing. but its a fine line, don't wanna get too close to the top ring. we should have it back together next year
you guys notice when @ tdc that the piston rocks back&forth in the cylinder, pivoting on the piston pin? push down on opposite sides of the crown to see this happen. i understand the skirt is a little smaller than the top but i found it odd.
dropped the maz/pe h/g off @ the shop on the way home this a.m. talked to the owner about doing an overall compression ratio test/calculation once the motor is done. he was down for that. i'd like to know just for giggles.
the saga continues...

Sounds good. Also the reason you have a lot more piston to wall clearance is because forged pistons expand more then cast ones. Also some manufacurers more then others all depending on silicone content.
As long as that mazworx gasket is new, you should seal well. Good luck.

Did or are they going to degree the 184cs?

reading this, it sounds like a proper warm up is even more important than normal with forged pistons.

supposed to be 12.5. the crown on mine appear very similar to/exactly like strattons. i think my pin is moved closer to the bottom ring though.



i gave instruction to do so, once the head goes on.

This could very well work out. We got some stock VE metal gaskets coming and check it out to see how it will work bored out to 92mm. If it works out ok, were going to bore 1 out and put it to the test.

That stepped decked blocks looks slightly different than the way we do it. But in theory works the same way. The N/A guys should not be having any problems with re-using the gaskets after the stepped deck block. We've been doing the step decking standard now instead of regular resurfacing.



As far as a bigger gasket is concerned, we have our gaskets made by the same factory that makes the PE gaskets. We've stuck with the design because its worked. Only until recently were we put to attention that the gaskets dont seal after being re-used on a std decked block. Anyone that has had a block done by us, we have offered to re-deck the block step deck @ no charge.

If you guys are interested, we can get a gasket made possibly 90-92.5mm bore in a 0.8m or 1.0mm thickness but this will require new tooling costs, but should be absorbed with a qty of min 50pcs.

It would be awesome if you could get a gasket made slightly larger then 92. That way they're won't be any issues. Its very cool you guys have offered to re deck the sleeved blocks.. I just won't be doing mine at the moment. Thanks for continuing to make improvments..

Yeah even the honda guys are getting away from the o-rings and using stepped blocks now. They seem to be very very benificial and I can see why they would.

Great job Mazworx and cant wait to get my stepped deck block back after your finished with it. Keep up the good work.
