6)Apex seal springs -

9)Corner Seal plugs
10)Silicone Vacuum hose

12)Rear main seal -
13)spark plugs -

Upgrades

15)Turbo oil pump -

18)Competition oil jets -
19)EGR block off -

Parts that I'm thinking about

30)Stationary gear bearings - (should I get the comp hardened ones??)

31)Rotor bearings - Should I get the comp 3 window ones' here too?

or is it overkill?


Anyone want to comment on the upgrades? Like the oil pan baffle plate, think that's overkill?

The car will be seeing solo II and solo I events. Limited street car driving, but will be street legal. Any comments are welcome. Hoping to hear from the two guys on here that have SCCA cars built up.

 

 

someone just say "yeah that looks GREAT!!!"

 

yeah that look GREAT!!!

 

sounds like a fun car!

are you sure you want to do a street port, though?
a broad powerband is what's needed for an autocross car, not a high rpm screamer.

 

that does look good, and I would go with a street port, as you do not lose too much low-end, but do gain a good amount of mid to high range power.

I am sure that you already know this, but the wiring harness in the 87 is not completely compatible with the 90 engine. Just food for thought.

yep, I know, doing the full conversion. w/ Street port I won't loose too much low end (N/A rotarys have none to begin with!)

Anyone else care to comment? Thanks for all the "that looks greats" hehe

 

that will put you in a mod class, will it not?
