It's a great day when you see this

Motor has 187,000 miles on it and you can still see cross hatches on the cylinders, doesn't burn any oil either.

Best part is Boport head going on plus you can really see how Bo unshrouds the valves !

Left is a heart head and right is a D Shape head.

Not a problem, the new head flows a lot better too. Max boost is set to 15 psi and now it hits at 2800 rpm as before it was 3200 rpm with my T3T4 turbo.

The stage 3 head is on and right now I'm using an old SVO turbo set at 20 psi and it running the fastest since I got the car last year.


I have a 50 trim turbo from Boport going on next and should put a few more ponies to the ground.

No I haven't but she'll spin the rear tires in first and second gear when on boost and rev's to 6K easily.

Plus I still need to install my FMIC.
