RX8 and RX7
 

I am sure this thread was discussed at some point and time on this site so please forgive me since I couldn't find it through the years of posts. I am still very new to the rotary scene. I was wondering if there is a major difference between the RX7 13B rotary and the Renisis I have in my 2005 RX8 GT? I just wanted to see if the turbo system on the 7 would be able to be crossed over onto my 8.:worship:

You should put a flame suit on.

Just trying to figure this out since I have a buddy parting out his 7. Niether of us know if it was possible. Not trying to be a bother. No where around here knows anything, atleast not by shop standards.

short answer, no.

long answer yes with major mods which would make it easier and cheaper to buy a kit for the 8

The short answer is more accurate. No. The turbo setup for the RX-7 is designed for that car and I doubt it would even fit properly in the RX-8. Also the manifold would probably not fit the Renesis which uses totally different exhaust ports (side exhaust ports). If you are interested in turbocharging your RX-8 there are viable kits designed for this car.

Only the turbo and wastegate would interchange. Everything is completely different..

yeah i should have said major mods which include buying /fabbing pretty much everything to the point where there's nothing left of the original kit

thanks for the input guys. sorry for the dumb sounding post lol. still trying to learn my limits and the workings of this car.

No worries, but remember there is a LOT of awesome information here on the site. Make sure to check out the various stickies and do a bunch of reading. If you are really interested in learning the workings of the car this is the place to do it. I recommend the Major Horsepower Upgrades forum especially.

Plus, the twin turbo is useless and extremely complicated to troubleshoot. Talk about vacuum lines :)
Go with a proprerly sized turbo, add the side exhaust port magic and you're done ;)
