ls turbo build

[1moretoy]

here is a pic of my ls1 motor with a turbo. Stock bottom end with a speed inc tu1 cam double spring kit and 60# injectors. I hope to be around 600hp with 6-9#'s of boost. running the stock 4l60e for now

can you tell me what size turbo you are running? Also, with the fuel injection did you have to have the accelerator pedal from the donor vehichle? Which engine is it? thanks

600 hp = short life for a stock 4L60E. I am curious if the #60's will be maxing out if you are close to 600 rwhp. Are those manifolds off a Vette, G8 or? Very nice build.

not to metion, 5.3s are going for $500. say they cant sell them because people arnt breaking them. friend of mine just bought one and bought twin turbo setup from ebay for $1200. keep in mind i know those turbos are cheep knock offs, but his money not mine.

I have a low mileage 4.8 I'll gladly trade for a 6.0 as well

The reason why the Lq4 is boost friendly is the lower compression ratio to the LQ9.

LY6 is similar...at 9.65:1 vs 9.4:1 for LQ4...tho it also has the genIV rectangular port heads and VVT.

motor looks sweet with that car intake and painted that color with the GMPP valve covers.

haha those ebay turbos are actually intriguing. Some of the older ones actually had epoxy holding them together, but seems it was only a certain run. Most of them now are just knock offs of proven designs, usually with slightly poorer materials or tolerances. That being said, over on the turboforums, people are going FAST on them. Junkyard motors + ebay turbo running 11's all day ain't bad. Let us know how his setup works.
