Anyone thought about an LS4

[nickb777]

Have been searching and noticed some of our friends in the States have done an LS4 TB upgrade
anyone considered it?

oooooh! can we get hold of these in the uk? is it really as simple as they claim? will it work on n/a engines?

 

[nickb777]

I may order one from the States and see how it goes

Perf figures quoted were of course for the 2.0 so hope to get a bit more.

Thanks Mike thats the one I found but couldn't post a link as I am at work

Don't know about NA's as I think enough guys had trouble with the 2.4 TB upgrade should be easier to map for an s/c (I hope)

if you keep reading it says that the TB is only for the 2.0 engine which is a shame.

boo

it's probably cheaper to buy it direct from a GM parts shop, the 68mm sc tb is only about $125

most likely ideal for the harrop sc and highly tuned GM sc engines, I doubt it will work very well on a NA engine

It will go on the harrop


Further features of the HTV1320-LSJ include:

Eatons latest TVS technology in supercharging.

Designed for the higher-flowing LS4 throttle body, but the original throttle body will also fit.

Might give it a try I have a guy who will ship one with the required plate for $100. only trouble I read about is sensitive throttle response.
