buster Member 7 Member For: 16y 9m 24d Posted 31/01/08 12:43 PM Share Posted 31/01/08 12:43 PM looking for any turbo gurus out there who could give me some advice on upgrading my turbo. I have a garret 700hp turbo which gives me 500@rwhp on my el xr6. It suffers from turbo lag a bit doesnt have much power down low. Once the rpm gets higher it comes on very hard and have trouble with traction. Is there a comparable brand of turbo out there with simalar or more power output but with less lag. Apreciate any type of advice thanks Link to comment Share on other sites More sharing options...

Do you know what exact turbo you have?? Any pics and spec of the setup?? I could possibly be something else, not that turbo that is creating your lag.6BOOST Link to comment Share on other sites More sharing options...

Id be looking at the tune if all the hardware is good... ie good flowing manifolds, piping, exhaust.Whats on the car mate? Link to comment Share on other sites More sharing options...

chuntington101 Member 8 Member For: 16y 10m 15d Posted 01/02/08 01:12 PM Share Posted 01/02/08 01:12 PM well I would recomend something like the GT40R (4094 not the 4088) and the GT42Rs (4202). should spool pretty fast on a 4.0ltr and would make killer power higher up. spool is a very difficult thing to messure. it will be different for every gear you pull in and is very dependent on other mods.
