New wheels were in order as the old rims were just too close to the calipers, even with wheel spacers there was about 1mm from inside of rim to caliper clearance. So late last year I went out and bought some second hand 16″ wheels. Some careful measuring suggested they would fit nicely over the brakes and not hit the guards. They were also lighter than the 15’s that I had on there. They were a little rough with rash and peeling paint…

Once the old tyres were off we discovered one rim had 2 dents on the inside edge. So off to the wheel repairer it went. Was pretty cheap and came back perfectly round. Then off to the sand blasters to shed all the flaky paint…

Then they received a very quick sand to remove the worst of the gutter rash. These are track wheels so a little character is ok. Then they were etch primed and given a couple of coats of satin black…

Wrapped in sticky tyres…

Fitting the new shoes was a different story. Plenty of clearance for the brakes, but the rim touched the bottom of the shock at full droop. I would rather do without spacers so I moved the lower shock mount up and inward. Now the tyre just touches the shock at full droop. I’m pretty happy with that…

A couple of new fuel filters and an 044 pump now feeds the fuel to the front. New blow off valve installed. Catch can is now in and ready to be plumbed to the pcv. Fuel pressure regulator also in and ready to go when I buy more fuel line…

Harnesses finish off the inside for now…

Dusty and in need of a wash…

A few shots of a weekend in April last year during its first ever drive since I’ve owned it. A few bugs to iron out. I need to make a trans dip stick tube so I can get some more fluid into it. Had some slippage when cornering. Tensioner pulley needs some modifying as it was allowing the belt to walk over the front of the pulleys. We lunched one belt and almost a second because of this. I since found the suspected problem and fixed it…

So this setup is at about its limit with the SC14 spinning way faster than it was ever intended. Mind you it is now doing everything that is asked of it. We put it on for a bit of a giggle but found with the right tuning it can pack a fair punch into a stock 3800. However to get more power now we need a better platform to start with so I managed to pickup a tidy VX Spac full of L67 goodness…

Sam checking out the stock tune…

I will start dismantling the old V6 this weekend ready for the engine swap…

Thanks for the list, what’s the reasoning behind the L67?

Are they that much better?

(NFI really only ever owned the V6 that was in my VR and the one in my VZ Tonner and wasn’t overly impressed by either, hence both are long gone)

Looks like a great fun car.

My dad bought a VH new in that same colour. So much green with the colour coded interior.

As is my understanding the L67 has a better bottom end more suited to boost? Either way the m90 is a bigger pump that will be more reliable in the long run.
