The T5 will depend on driving style

I don't have any experience with Pulsar. That said, haven't heard anything bad, and there's blokes running fast with them.

I can find the cam spec

I don't have any proof other than being told that the AU heads flow better than the earlier heads

From what I am aware, the only difference between the XR6 head and the VCT head is the VCT. As far as the BArra ECU, pretty sure you would be better off with individual coils.

So, I found an ED ECU in my parts collection that was the correct part number! Installed, and problem solved with no money spent.

I think I will try to find a second hand ECU. EB-ED 4.0 auto with 3.23 diff is the same part number, so pretty much any EB-ED 4.0 auto ECU will run it. If that solves the issue, I can then try to find the 100% correct ECU.

Gday all My XG starts and runs well cold, then as it warms, it develops a miss. By unplugging injectors to test, it seems to be missing on 2, 4, and 6. This corresponds with Bank 2 injectors Any ideas of how to test? To me it sounds like I need a replacement ECU.

Look at VSB 14 and VSI 6 Vehicle Standards Bulletin 14 (VSB 14) | Department of Infrastructure, Transport, Regional Development, Communications, Sport and the Arts Light vehicle modifications Lots of information

Interesting point. I don't know. That said, I know have blokes that have sought out an early block to solve the potential problem

That would work. I was thinking you might have difficulties otherwise. I can't see a way of making it legal other than the EFI.

What gearbox would you run?

The 650 cfm carburetor isn't too big for a Cleverland. Whether it's the right 650 Holley is unknown. A dyno session would be very helpful if the tune is way off, but less so if it's very close.

I agree with Deankxf. Don't be concerned with 2500 RPM at 100KM/H, that was how they were designed to run. And, it will run out of power before it gets to critical RPM , so top speed will be a power limitation, rather than an RPM limitation. 4000 RPM will be approximately 160 KM/H, 240 ish at 6000 RPM. The low performance Clevo won't have a hope of hitting that

I really like the look of the RS wheels
