Deck and compression height

zer099 · 05-08-2017, 10:53 AM

I might have failed at searching but I couldn't find the answer:

Does anyone know the deck height and compression height on the VQ37VHR engine? Thanks!

If nobody comes up with an answer, that info may be in the FSM (link in my sig).

I looked in the FSM and didn't find it in the section I presumed it would be in: Engine Mechanical. Thank you though.

for what its worth-
Brian Crower web site states the following for block height, which i believe is the same thing as deck height-

Stock Specification
VQ37HR 95.5mm bore x 86.0mm stroke - 8.795" Block Height

i did not see any specs on compression height.

Thank you. 8.795 inches is about 223.393mm which is close to my guess of 225mm.

I reached out to a few piston companies to see if they had the information. If someone happened to have a piston laying around that could measure it that would rock.

Give Ben Pila or Clark Steppler a call at Jim Wolf Technology - (619) 442-0680 Mon-Fri 8am-5pm Pacific Time Zone

They will have the info you need.

Again- FTW more after market specs, these are from Wiseco-

30.43mm CH is what I found randomly on an other forum as well. Though the Comp ratio is 9.0:1 on those pistons so I wonder if they moved the height any to achieve that or just dished the piston more. Thank you again.

Believe those might be induction pistons at 9 CR. Should be 11 CR for stock N/A.
