Are there two different evo9 engines?
A generation1 casting and a generation2 casting?
if there is how can I determin which one I have.....
the reason Im asking is Im having valve seat fittament issues with a supertech dual spring kit.

 

all the same.. if your having a seat issue you have the wrong seats most likely..

 

ok well I bought spr-m1007d
seat-M1007d/fp
ret-M65/TSTD
VS-H6.6E
VW-H6.6I

the guy whos working on my car (evo9) 2006, was told by supertech that gen1 casting might require
seat-m1006d


what are your thought on this?

 

more help!

 

ttt

 

this is all the help you need. All the motors are the same. unless you dont have a 4g63. all IX are the same man maybe get a new guy to work on your car.

 

i see your in cali what part? if your in socal i can direct you to some good shops.

 

for some reason im being told the the part i have seat-1007d
is not correct
but part number
seat-1006d is......
this is from supertech......I dont think the guy working on the car is the problem.....he has his own evo8 with over 1000 awhp
plus he working a civic race car, and has two lambo's there one yellow murcielago (v12) and one orange Gallarado (v10)
so i think its a wrong part.......
