63 heads & basic stuff ? ?

Post by dave b »

dash 2 Vs DOHC.wanting to know 1st are dash & DOHC turbo pistons the samecrowns as non turbo eg;-is the lower comp in the pistons or head.Will dash head run with std non turbo block (std non turbo compression ratio).Are DOHC turbo & non turbo heads the same. What i've done is stuck a 4g64 in my L200 ute (was 4g54 ),a dash eng in the shed & know a bit about the interchangeabitity .Do I go 12v 16v turbo or non-turbo.The 64 bore is 86.5 (60thou)ova std 63 so should have no probs gett'n pistons,but stroke longer thus torque not revs.more basic info mite settle my brain drain.CHEERS

I only have half a blank look, it could be a blank or a look depending on what half I have :D

The compression is in the pistons.

It will run on a std non turbo block but just different compression.

DOHC non-turbo and turbo heads are almost the same, I think the only different might be in the cams, springs and inlet/exhuast ports.

Youy can choose what ever you think is best, just remeber the comprssion ratio will change and with a turbo engine running high compression and bored, you should stick with JE 8.5:1 pistons and forget about the Weisco 8.9:1 set.
