Since my LS1 blew up in my 99 vette, I'm going w/an LS2 402.
Just curious what mileage you guys are getting. Thanks.

 

Im still getting 26-30 mpg with 30lb svo injectors and a 505 RWHP 402 LS2.

 

Damn Mike, what kinda cam and heads you running on that to still get that MPG?

Dixit

 

Damn Mike that's good!

Hell when I was beatin' on my LS1 heads & cam plus... I got about 17-18 mpg & about 25 mpg takin' it easy.
What heads & cam are runnin' on your LS2 402?

 

AFR 225's with TEA's CNC Port. 346 cfm on the intake.
CAM 248/255 .640 .640 on 110 LSA

I get that mileage crusin in 6th.

 

I'm getting about 16.7 MPG if I mostly lay off the boost.

 

I get 26 on the highway

 

I get 25 mpg on the highway with 4.11 gears.

 

We just finnished installing a LS2 402 in a customers C5. Not even broke in yet, and it's getting 18-19 around town, and just over 20 on the hwy.

Cam: 232/240 Duration, 595/608 Lift and 114 LSA.
Heads: 59cc AFR 205's

Motor is 11.2 to 1

Dynatech 1 3/4 headers, FAST 90mm intake, & LS2 tb

Did I mention that I know have a harness that will plug your LS2 tb dirrect into your C5!.....$64.95 & in stock!!

 

What about plugging an LS2 into an LS1 F-Body?

 

The f body is a cable throttle not a drive by wire. Wish I had something simple but I don't.......very sorry.

 

Hopefully someone will figure out how to make the LS1 knock sensors work with the LS2 block by the time I am ready to buy a new motor.

 

They work now!! Race Tronix has a plug and play harness for the knock sensors, and the cam sensor. We just did an install on a C5 but we extended the stock ones.

 

Can you send me info on it, please?

 

This may sound odd, but is there the reverse ??
We use the C5 electronics in our Hurricane manifold, and need a patch loom for fitting this manifold to LS2 vehicles.

 

So... never?
