I am currently in the process of building a s5 and was wondering if anybody has had experience, good or bad, with the rotary aviation kit.
any other suggestions would help.

 

Theres tons of info on this site about the pros and cons of them, just use the search button and you'll find some.

 

I remember when felix redid his engine with the rotary aviation kit, his coolant seals blew. There was a big stink about whether it was the kit, or felix.
Felix said that the coolant seals were too large and just barely fit properly. Others started going ape **** saying that when they used the kit it worked fine and was great. It was interesting to say the least.
Search for it.

 

LOL, they come too SMALL to fit, not too large, you have to stretch them by HAND to fit. So either felix totally fucked that up (VERY likely), or he just didn't pay attention when he put it together, which caused the pinch. They work just fine.

 

when I saw the pictures it looked like a pincj ,b/c a part of the seal was eatin up..

 

Agreed. I've got 20k on my RA rebuild (in just over a year), and it's fine. Getting those seals to stay, though... You had to basically hylomar them into the grooves, and use the housings to press them in so they's stretch out & stay. I can see it being easy to screw 'em up.

im doing my rebuild with oem coolant seals . very basic and do the job just as well in my opinion

 

yea i rebuilt mines with that kit, poped 2 o rings and had to run off to rotorsport to order new ones lol. but im not sure if this is a tip but, use oven cleaner to clean up the rotors/housing. this thing cleaned it to a point where it was shiny.

 

When I installed my RB coolant and combustion orings....they went in just fine. Compared to all the pita things I have done to my car...this was rather easy. Of course it was over 100F outside when I did this with Santiago...so maybe they were easier to work with in the heat.

And of course I used holymar to hold them down. And I was very carful watching the housings come down to make sure they didnt slip out of place.
