I have a 1991 acura integra ls circle track race car. The engine has 4 races on it since a full rebuild. It now has arp rod bolts, and fidanza flywheel.

Now on to my questions, It has crane cams #101-0012 ( lift IN. .400 EX. .388 duration IN. 232 EX. 250). It also has a megan racing header with about 5 feet of 2.5" exhaust pipe. Does this car need to be dyno tuned with just these mods? Seems to run really strong now. If I don't need a dyno tune what about just having a chip burnt with only a higher rev limit, is this possible?

I want to add a IM and TB and was looking for suggestions on which brand to consider.

And lastly when doing tune up what brand parts do you reccomend? NGK is what I was thinking.

sorry this is so long but all replies will be greatly appreciated. Brian
