That's at least mostly responsible for the stickiness - def. don't drive hard until you get the mounts sorted! usually the front one will go and the side ones will still be fine, but give them a good check anyway.

Has anyone bought raw polyurthane stock and made their own bushings? There is a website/blog in which two sweedes convert a old porsche 911 to work with a b234r motor on the cheep. And they made all of their own bushings that way. But I dont know where to begin in choosing the correct poly material. Or know who sells it. I'll try to find that website when i get home, i'm pretty sure its in my bookmarks.
edit:/
http://project911.luminasweden.com/ <-thats the website, but its either down or gone.. Google has some of it cached.

I've made some bushings, motor mounts, and other castings using polyurethane. I've purchased it from Mcmaster-Carr and hobby/casting websites. You really should use a vacuum chamber and vacuum pump after mixing and after pouring the mixed polyurethane to evacuate air bubbles. After it hardens in your mold you can cut, drill, machine it if you need. McMaster sells a preparation liquid that you can use to help improve it's bond to steel.

I couldn't find it. I have had it explained, but can someone hand over the direct link? It's supposed to be a great upgrade as it gives more travel to the idler gear for a more positive engagement.

Thanks

Haha! Yeah, it's been for sale for a few months now. Hasn't moved for a while due to a bum clutch master, but runs like a top. I planned on tossing on some Bilsteins and Hellas to rallyx/TSD the hell out of it, but I have a 30yo woman and a 2yo girl at home that say otherwise.:) Give a shout if one of you guys wants it cheap. Unfortunatly, I'll need it gone soon and it's WAY too nice of a car to junk; shell is solid, low miles, needs an easy fix. I just mainly want to sell off the current herd(VW Golf, Screwbieru Forester) and get a super cheap Saab turbo to work on, even if it's a NG900(blasphemy).

Thanks for the offer, but at this point I cant afford a 4th car. Even though it is a non-turbo and will probably be easier to work with getting prepared for rallying for next yr.

Edit// noticed you want a c900/ng900 turbo. I would possibly consider trading car for car. Even though I would be on the loosing end value wise, it would be less work for me since rally america rules do not let green racers use turbos for the first 3 or 4 rallys... But the turbo is what makes the car so much fun. So I dunno.

Boy is that tempting. I don't think a trade will work for me right now though. I've been out of work for nearly two months and I mainly need cash. I also don't really have parking for three cars, despite that I have three cars... the landlord has been threatening eviction for a while now.:)

Rest assured that when you do get an N/A car, it is still very fun without the turbo... no worries there. That kinda sucks that Rally America won't let you run a turbo car; it's not like it's a 400hp RWD coupe or something.
