im tryin to build a s5 motor and im goin to buy a 90 and i want to modify it obviously and to start i thought i would do (new rotor housings, 3mm apexi seals w/ dual springs, new oil pump and chain, rotors race cleared, rotor housing cooling modifacations wich involves cutting fins in the coolant passeges in the rotor housings, oil passages enlarged two piece eccentic shaft, street ported...thats what im thinkin i want to do first. im goin to prolly run a T60.

TELL ME WHAT U THINK IF ITS A GOOD START OR NOT!

 

What are your ultimate goals for the car. Are you lookling for a certain horsepower, quarter mile time???

 

i think its expensive. sounds good though.

 

sounds very expensive. Will this be the first rotary you build?...assuming you're the one doing the rebuild.

 

I think your just startn to realize that you have no idea why you want 3mm springs and stronger springs..

 

^lmao, seems im not the only one who had this feeling

 

i think trying to fit an na engine with a turbo is always a bad idea. go with an s4 turbo block.

 

why are you going with 3mm seals? 2mm are more then enough

 

Unless you want some serious HP....you don't need 3mm seals, or your rotors are out of spec. Also....two piece eccentric shaft???? If you're gonna step up and play a T60...you really need to start thinking about how you're gonna get fuel...Ignition....etc.

 

I think you're been reading too much out of the Racing Beat catalog...

Sign me up for those APEXi seals. ;-)

 

LOL
Anyway, I'm guessing you are trying to do this with an N/A block? If you want it Turbo'ed, just get a turbo. About the only reason to turbo an N/A car is if you already have one with a lot of other work done on it or you just want a challange. Either way, its much easier, and prob cheaper, to just get a Turbo and start from there. You should get the car, get it running well, and get to know the car before you start throwing parts at it. You have to be very careful when you mess with turbo rotaries or youll end up with a blown motor.
