I need to know the bolt size / thread pitch and bolt length for the motor mounts when adding a oil pan brace.

Thanks in advance.

 

Here's what I used: http://tinyurl.com/7lqqauw

 

If you mill the arms 3/16" to keep engine height the same, would you need longer bolts?

 

Thank you Mahjik. That is the link I could not find last night. Its what I used last time - but I have another engine and another brace so I needed more bolts.

Sgtblue, I guess you COULD mill the arms down, but I'd be resigned to using an angle grinder or something.

Maybe I should have used the angle grinder in the spirit of what I'm doing. I am putting a native FD block into the shittiest RX2 EVER and going to race it next month in the 24 Hours of Lemons at Texas World Speedway!

 

Good luck, let us know how it goes.

 

Modified the RX2 subframe to get the FD engine under the hood and added mounting points for the FD rear mount. Using an SA RX7 transmission since the RX2 transmission had the starter ON TOP!!! I'm no automotive engineer soooo it either WILL or WILL NOT work.

Waiting for a clutch disc so I can get the engine in.

Putting cage in as soon as it gets here.

Shoehorning an FC radiator in with an FD block... I estimate that there will be 1 - 1 1/2" between the engine and radiator.

Going to have to use pusher fans.

ALSO, looking for RX2 brake calipers. No autoparts outfit has them (although they are listed on all of their websites).



^^^ RACE CAR!!!

 

^It's is ugly. But for the year, surprisingly little rust. Up here in the rust belt it would be ALOT worse.
Have fun.
