Looking at doing some engine work. Started looking into the l92 intake, which means I have to change out the heads. Just wondering if it is worth my time to do the switch. what kind of numbers would I see? Thanks
Andy

 

well i will have #s soon check my l92 top end swap thread it shows all of the work involved

 

Looking back now, I probably would have gone with the Trickflow 220c as cast heads. I prefer cathedral port heads.

 

did you do an l92 set up?

 

No, because I didn't feel like having to change the intake, TB, convert rails to return, etc. I would do trickflow heads before switching to l92, but that's just me

 

oh, it just sounded like you had done the top end and was wishing you didnt, when you said "looking back"

 

putting down close to 470 rwhp

heres my graph before i swapped the headers and added a EWP and a little more tweaking on the tune.



hadnt gotten the new graph yet but will soon, got just a few more tiny mods to do

last time it was dynoed is when i swapped to kooks step headers into 2 borla's and added a EWP water pump. and tweaked the tune more and gained 469 but lost a tad on the tq side

i wont stop until i pull 500 to the wheels, oh yeah i still drive it daily


future mods, FAST 102 and the big mouth and a new spected cam !!!

 

Yea, but you ended up changing the intake anyway lol

 

I went to Lingenfelter CNC L92 heads, I love them!!!

 

what is needed to convert the l92 intake to a return fuel system?
