I did a quick search and found no definative answer. Just want to know if I had an S1 Greddy kit, will it fit the S2 engine/chassis?

Thanks

 

Yes it fits physically. Will the S2 run after having it installed? Yes, but not well because there is no easy way to tune it due to changes in the S2 ECU and other things. It's been talked about many times, search a little more and you will find plenty of info.

 

Cool thanks!

I guess I suck at searching btw.

 

I know of one that has been running for years properly with a different ecu, everything works properly too..
I know this thread is old, but this forum is DEAD...

 

So, a Greddy S1 kit + 1 mystery ECU and we can run an S2 Turbo? Without a CEL?

Is there any way we could find out more about said mystery ECU? It seems to me that that little gem would open up all kinds of possibilities for S2 owners (even if it were some kind of hacked S1 ECU). I am sure a lot of owners would like to know more.

 

There's no harness made yet for anything, but you can do an ecu I'm told. there's nothing like the cobb, but you can do a haltech Stand alone and some other options. It's a bit pricey , but i'm doing mine in the spring to tune it then adding a turbo ... but not the Greddy ... I think there's better ones out there that fit the s2.

 

I won't post the info out in the open. There are too many people that copycat our business.

We have begun a S2 Rx-8 with our low mount turbo system using this ecu...

 

unfortunately the ECU's alone cost upwards of $2k to purchase/install/tune
