I'm running a F2T mazda with the stock VJ11 turbo,with a home built exh. manifold(setup is in a 90 B2200 Mazda pickup) with MS2 for fuel & spark control.The exh. mani was built with 1/2 cold rolled plate for flanges,schd.40 steel pipe.I know that this turbo is SMALL making the exhaust manifold run extremely hot(I would guess from color about 1100 deg. F) I recently added an EGT gauge with the probe in the orginal O2 senser port(back of the turbo in the orginal casting)

With all of that the first test drive the new gauge showed me a high temp of 1050 F(no boosting ,just normal driving) and settling to about 850 after letting the engine idle for 3 or 4 min. Are these somthing like reasonable numbers?And at what temps should I become alarmed?This project is my first shot at turboed anything so I've no experince with them at all,but have been working on cars and engines for ever.
Any in put would be great
