i have a greddy 18g turbo and no name header for it and a tial external wastegate i dont now anything about turbos so could someone help me. How much could i get for it???

 

There's no way you have a header for a turbo. $250-$300 tops.

 

you mean a turbo mani. depends on the brand.

 

I LOVE GReddy 18Gs. what are you trying to do with this car? I've had plenty of people use it for over 350whp keeping A/C and P/S.. go try to sell it if its killing you that much.

 

on how much boost? I only made 260whp on a stock block GSR on 14psi, I did still have the shitty cast downpipe it comes with and running internal setup as well

 

I did 260whp on 10psi on a Stock block GS-R in 1999. Somethings changed on your setup here. It was also with the stock equipment and a 3" exhaust.

But 350whp can be done by 22psi give or take.. That's with an upgraded actuator for 41lbs/min

 

I'm sure he meant manifold. Turbo and manifold is worth that price, but when you add in the Tial, it's worth more.

 

I'll give you $150 for the turbo.

 

isnt the 18g a t28 turbo? Shodan, i'd love some more info on how over 300 can be obtained with the 18g's as i have a kit laying in my garage but i was under the impression they were only good up to 300 before running out of breath.
