Good luck trying to find the solenoids and the engine. I turbo'd my DE and it will be very hard for me to go back to NA. The power/money factor is much better for a turbo car. I have the S3's which cost about $550 and they give me 20+ hp, name me a mod for a NA SR20 that will give you that much hp for that price.well, what about an SR20VE NEO VVL!
