whenever he broke the timing belt the engine was trash. so he had it removed to put a '91 s2 engine in it. And being as curious as i am i went and checked the HP of each. '85.5- 143hp.....'91 s2-211hp

thats awesome , but seeing as this is not the stock engine, would i be unable to enter some races in auto-x? because technically i dont have any performance parts on it..

No you can enet autox you just won't be allowed to run in the stock class. Most likely you would be in Prepared, or modified

vro944om

what cars do you usually find in prepared or modified? because i dont want to be totally screwed out of my class.

Actually looks like you could run in the street prepared class

vro944om

crap i would have to be in modified because i have a sub box instead of rear seats, i guess i have more work to put into it before anything.


the PO put them in, so i dont have seats, or any mounts... plus the whole area is covered with carpett

xsboost90

modified doesnt mean stereo etc. it means engine mods or power mods like trans etc.... improved classes are for cars w/ suspension and brakes etc....

vro944om

well taking the seats out would be a weight mod wouldnt it? or is it so slight it wouldnt matter?

bjzorn

like I said you would be in Prepared, maybe street prepared. Most of the PCA Auto's that I did where pretty cool about it.is the whole rear seat removed or just the top half?

vro944om

the whole rear seat, but if you didnt know what a 944 was, it looks stock, it doesnt look like i intentionally stripped something.

bjzorn

oh so a RS carpet kit. I did the same thing to my 944S2. It looks stock and people always ask me "why didn't Porsche put a back seat in the car?" I have Linen Carpet back there and it looks factory. you should be able to run street prepared.

Btw where is autox at? I am in the DFW and if tis close would love to come check it out

vro944om

awesome, i might have to push the limits on that class..

kandyinmyvan

How did you not realize that you had an S2 engine? Pretty cool to find though

944CS

just run in stock class until someone bitches

Scootin159

In SCCA autocross you would be in either FP, XP or EM - none of which you will be competitive in with less than 300hp, more than 2100lbs or less than 9" wide slicks.]

That said... still go - you'll have fun, and at the local level in those classes it's likely you'll only be competing against other people who got 'screwed' by the system too...
