I am not sure how that would effect the weight. Considering the piping/turbo/FMI etc. What I hope to eventually do (funding/time/length of ownership considered) is go with a aluminum m52 block, then with lightweight battery, cf hood would get it closer to stock balance.

The other consideration for me is that a turbo m44 wouldn't be legal here in California, so I am trying to get something I can get smog legal.

Did a compression to make sure the engine is actually healthy. Got 150psi all across (forgot to keep my throttle open . . .) so it is really healthy, it did get a 3way valve job/headgasket etc. I think once the exhaust is cleaned up and shifter/suspension is tightened up it should be fine.

Update:

1st Tank of gas 21.7MPG (M52 w/s52 cams TRM tune and 3.46 diff, 195/60/15 tires)

2nd: 23 MPG

3nd: 23.4 MPG

4th: 23.7 MPG

5th: 22.5 MPG (swapped on DS1's 225/45/17)

6th?:22.8 MPG

Seems like ~23mpg is my norm now. This is with ~70% freeway ~30% city, but I would say ~30% of the freeway driving is after work, bumper to bumper stop and go driving.

** Switched to 89 Oct with Chev/Tech - I thought I got some better MPG with 89oct! first two fuel ups was 24mpg, but then third dropped to 23 again... sigh.

24.0 MPG
24.0 MPG
23.2 MPG

** Alignment, CEL (camsensor and intake temp) fixed.

24.9 MPG
21.5 MPG
24.8 MPG
23.5 MPG

Still seem to be stuck at 23ish MPG, if I drive around 70-65 on the freeway with mostly freeway I can think I can break into 25 MPG as I got really close above a few times.
