what are the major differences in the seals. i thought about running a NOS after my rebiult but i heard that 3mm seals break faster then 2mm. the NOS kit is optional i still had a unverisal kit from my honda so i thought about useing it. the main question is whats teh differences? i am think if 3mm is better then why dont everyone just get it instead of 2.

 

why do you want to run NOS? thats almost always a bad idea.

if u have a stock reman use the 2mm.

 

This has been discussed numerous times before over the years.

 

Sell your 7 and stick to hondas...i can tell already youre going to ruin it.

 

I take it a NOS and RX7 dont go togther :P

 

from what i have read its just difficult to get the timing right and stuff, tuning is always hard. If you want more power get a bigger turbo!
