Was a ZR4, now a VR4

[JayRome]

Its been a while.... a long while..... unfortunately in that time, my widebody ZR4 was written off by a young driver who decided to drive head on into me at an intersection..





Lucky enough, i had built a VR4 for a friend who doesnt drive it that much and he decided to sell it to me... so a new project begins...




Build update shortly....

 

[JayRome]

Pretty much stripped and swapped everything over. Rebuilt the HVAC system with new foam and clean insides, ripped out the old climate control and A/C and replaced with standard dials and deleted center vents. Ran wiring required for gauges etc while dash was out. Reinstalled my EvoX seats and Evo9 steering wheel.









Removed engine and gearbox.



Removed all the ABS crap, replaced with standard braking system and GTO brake master







Reinstalled my old built hybrid 6bolt/evo7 engine.

Unfortunate rust repair....













Filled the centre carrier bearings in using a 2-part silcone mix with a shore 45a hardness. Should hopefully stop the slop in the drive line.

Interesting repair. Let us know how it works.

Its been a while. New location and waiting for garage to get built.




Evo X wheels (surprisingly hard to find for sale in Aus)



Testing 6 piston caliper clearance



Fresh coat of paint



225/40R18 tyres




Fitment: approx 10mm tolerance from rim barrel to caliper and 4mm from caliper to wheel spokes, no spacers needed.

I knew those calipers looked familiar, I have a pair of them sitting in the shop from a Cayenne/Touareg, they're big units.

 

[JayRome]

have been chasing a cooling isssue at "higher" speeds and realised that the only difference between the VR4 and the ZR4 were the bumpers... so here we go...





Took off 5.1kg of weight off the front bumper reo



Alloy air dam and some plastic garden edging to blend it all in....
