So is there any extractors for a h20a now?

[DarkHorse]

Not that I'm aware of, but the head should be the same as the H25 or even H27, and Wildcat make extractors for them.

I've got some on order, will let you know how they go when they turn up.

Has anyone retarded the inlet cam for more torque between 2000- 3000? Peak torque is at 4000 and ill just about never rev it to that

[DarkHorse]

Why not? It's perfectly happy revving to 4000rpm...

Improving the breathing (exhaust, snorkle) should fatten the torque curve out a bit shouldn't it?

It's auto and only revs til 4 with lots of throttle

Haha mine only starts to pull around 3000rpm. From then till 6000 is where the fun is.

My mother has an auto, kick it down a gear, or move the shifter manually, it will get to 4000+ easily...

I know this is an old thread but I’d just like to answer the question. Yes the extractors designed for the h25a fit the h20a.

You need to extend clutch line out of the way re-rout speedo cable and shield brake lines on r/h bank in engine bay.

I’ve seen the question posted a lot with no answer
