the higher boost on the stock turbo tends to heat things up a lot, and if your running an automatic with the smaller stock turbo its only going to add to the heat problem.

white is leaner, black is richer, and you want a light brown ish color on the spark plugs.

can you identify if its running too lean by looking at the plugs? as in unsafe a/f ratios? I agree its running lean. would it fuel cut if it was starved enough? or something like that. theres no sign of det. on any plugs.

so brown-ish color is good. on which part of the plug? on the electrode or ground terminal or both?

Its a 5spd, with the stock 1g turbo.
The previous owner claimed it has a rebuilt block, with .40 over pistons.
thats all he stated. he didnt even know what cams it had.. so as far as internals go i have no idea whats done to it. all mods i listed are the things i have seen so far. the only thing i didnt put on the list was the morosso oil pan, oil feed relocation & aftermarket oil return.



thanks!
