One key point your missing with the turbo is ignition.
This is the issue I'm trying to work out at the moment, particularly boost retard.
What was the compression ratio from teh 88250 engines?
They were still listed as 18RG at that point in the time line, just before the 18RGU, so I would have thought that they would have had the 9.7:1 pistons in them or 9.2:1 in the 18RGR.
Unless they are the engines that had the 8.5:1 pistons that I saw at a swap meet, never heard of those before, but there it was, cast into the dome top.
I've heared that 88250 heads had 45mm inlet valves but still had the small exhaust valves, can any one shed some light on this?
I reckon you'd be scratching to get 200hp using 9.7:1 stockies, 88270 head, 88230 cams and small other mods. I;m thinking more like 160hp.
88231 cams run out of puff at 6400RPM, sure it WILL rev out to 8000RPM no worries, but not if you want any sort of power or torque.
