Shit the 40r is a decent size turbo but its really not all the big, There are guys on here that were running 40-42r's on 4 cly's the 40r is idea for my build.
the 26 handles well to huge cams, and all the head work ive done the 40r is nothing big for the motor, I wanted bigger, the 35R I had on my previous 25 I was seeing full boost at 3900 rpms and reving to around 9600 rpm, you have to remember its an inline 6 and are very boost hungry and rev like no other. as long as its not a shittly old rb20. a well balanced inline 6 with the right cams and huge turbo is a deadly combo.

as for the evo, I have had alot of years working with the 4g63. I have done alot of business with john shep and dave burshur in the past on my previous cars. I already have alot of goodies sitting in my basement waiting for the car.
but within a few years id love to have 10second pump gas evo just like jeff's for a weekend car. hopfully now with work picking up , im not going to be able to search like I have been the past month or so, I will have to wait and hold off till I get time from work, hopfully I will see the evo in my driveway before summers end.
