Upgrading Dynamic4 to VR-4


Well-known member
Hello @ all...
I'm thinking about making a VR-4 out of my Dynamic4...
I saw many of yours are aprting out some cars - is there a real chance to get all parts together?
After studying ASA I noticed the only differences between both modells are -
- airfilter
- headers and turbo
- oilpan
And, of cause, some internals at the engine.
I've a six-bolt 4G63 out of a n/a 1G Eclipse 2WD in spare, that I could upgrade with other rods and pistons - the only difference I could notice.
Any suggestions?

The transmissions are also different (weaker in the Dynamic 4) since your car is the equivalent of our GSX. You will want to look into a transmission with matching transfer case and rear-end. See this thread here

The Dynamic 4 brakes are also the smaller single piston 266mm/256mm (depending on year) up front. Rear discs are the same but rear brake caliper piston sizes differ between early and late models.
