stick a leaf blower up the exhaust pipe while drilling. Any shavings will blow right out and back at you. I drilled many manifolds like this and never had an issue.

Turbine inlet temp is the only thing that matters. Any probe post-turbo is useless. Drill the collector right where everything merges into the turbo for the best reading.

11 forum pages of fuel plate, mufflers,  and more on a 94 Bluebird BMC 37' (mechanical 8.3). Includes dyno testing results.

You will have to join the WOG forum to view it.  This was my previous coach and my post thread.  I no longer actively follow that forum.

We tow a 5,600 lb Jeep Grand. Noticeable improved power by replacing mechanical fuel pump, injector pump return valve & muffler.

We added a pyrometer (hole drilled after turbo & use lower max acceptable temps), turbo pressure & electronic fuel pressure gauges, all of which should be installed before any engine mods or parts replacements so there is recordable baseline.

We never overheat on mountains in warm temp now by driving with light throttle, downshifting, watching EGT, boost & tachometer.

For pyrometer, see recent posts about integrated VEI probe
