Im going to rebuild and port my motor soon, and was looking at the RA rebuild kit. Im going to be shooting for 400-450 rwhp with a 62-1, but Ive noticed several posts saying RA seals are not designed for more than 400. Anyone have any info on this?

 

naw

use the stock OEM springs and give it good break in and you should be good

 

so use RA seals with OEM springs?

 

there's like a HUGE thread about them. SO go read that and let us know what you found. Also call them and see what they have to say about that.

 

Yes trust me
the weak point on the RA setup is the springs

There not heat treated like the stock ones(less spring back force)
and have seen them collapse on high RPM N.O.S cars


I have talked to half-dozen rotary mechs in my town
Like Kilo 2004 all motor champ

all said the RA seals are good just the springs are weak

I then called RA and asked if I could use the OEM springs
and they said "yes" there interchangeablewith there seals

My new motor is done
I'll be dropping it in this weekend

and my goals are to make 100HP more then you with the RA's
