Default *NooB* AVO 2.5RS Turbo Kit

Greetings all,

I had some questions regarding the kit that AVO Turboworld has for the GC 2.5RS
here.

1) The downpipe already has a high flow cat on it; would it be wise to purchase a mid pipe without a cat, or is it better to use the stock converter in conjunction with this one?

2) Would it be wise to upgrade the clutch in my RS to an Exedy or ACT plate to extend the life a little, or is the stock going to handle just as well (from the turbos perspective, I know an aftermarket clutch would have better pressure, etc.)? What other upgrades might need to be done to accomodate the turbo?

Thanks in advance

1) I believe the DP replaces your stock converter section.
2)You will need to get a new clutch in the near future but which one depends on your driving and clutch pressure preferences.

Also, when asking the question about the clutch, go read some posts about 2.5rs tranny problems (too much torque). I too am researching turbocharing.

I have looked through the posts most of the evening and was not really able to find anything useful regarding problems with the tranny itself, just clutch plate.

If there is something major that I can't find, please feel free to link or post it

Note: I am not really looking to punch up the psi on this system for amazingly low times or anything like that. I'm quite happy around 5-6 psi and around 240hp. I rather loathe driving fast in a straight line anyways

Thanks again!

I haven't seen many on this board, but i know on many others the RS tranny is a weak link (usually due to forcing all of the torque from the ej25 into the gearbox, and not letting it out due to the AWD, causing the tranny to take the load, and break).

http://www.rs25.com/forums/showthread.php?t=3541
lots on rs25.com website, somewhere there's a 15 page or so post about turboing a 2.5rs, this might be it, but i'm really tired right now, lol.

there are others, but i'm really tired right now, might post again tomarrow.

I hate driving in a straight line too, that's why i'm only going for 4-5psi. At least until i build up the rest of the car a little bit more, then i might go for more power (this means suspension, weight, tranny, etc.) The high compression on the EJ25 makes more boost much more dangerous than most cars. Which is why i suggest you research some engine management too.
