I have a Injen Intake for sale, less then 500 miles on it. Going with a GT-350 TB to go along with my manifold and the GT350 specific intake route. Call text or PM me 586943eightfive70. Great intake for someone worried about intake temps and aren't committed to a tune. 220$ OBO shipped. I have...
injen makes a nice non tune closed box intake. The stock MAF diameter is already bigger then the TB. Filter surface area was my main concern. Quality is excellent. JLT if you want some open element noise, Injen if you still want a close box.
You need a tune 100%. Just buy one, wakes up the car. 91 around here is expensive, E85 is cheaper then everything else. You will use about 30% more fuel FYI
It is a stock diameter crankshaft damper. But it is lighter then stock, and 30% lighter then the ATI. I know some people say that a lighter damper may hinder dampening performance, but MMR is running it on race engines running close to 9k so it must be fine.
Only thing I wish the base GT had was a analog oil pressure gauge, but synthetic oils are so dam good now that it it shouldn't be a problem for general driving, drag racing. If I road races and was at WOT for 5+ laps I would start looking at heavier weight oils.
