I'm about to do some fuel mods on my TII.

Last thing I want to do is blow up my newly-rebuilt engine.

Mods planned is an FMIC, apexi sfc, 720cc secondaries and electronic boost controller.

From what I understand the 2 things I need to keep an eye on that can cause detonation is running too lean and high intake temps.

I'm picking up an air-fuel gauge to monitor air/fuel, but my question is--what can I do to monitor intake temps?

Summit sells some good air temperature gauges that should do a good job, but I don't know if the gauges read up to about 300 degrees F, which is probably much higher than you'd ever see. If you go with a good front mount IC you won't have to worry about intake temperatures.

go haltech ! that would make the car run alot better

I recommend getting your car tuned using a wide band setup which utilizes a UEGO oxygen sensor and special air fuel gauge for the correct air/fuel ratio. Also the front mounted intercooler will help to reduce air intake temps but you should always use high octane fuel 93 and get your timing retarded if you plan on running boost above stock levels. Water/alcohol inject will also help to prevent detonation and will enable you to run higher boost levels using pump gas. Also, make sure you keep that motor cool!! Check out an alternative cooling system like Evans NPG+ non aqueous cooling fluid. They also make some decent aluminum radiators. Do you homework before you turn up the boost dude. Good luck!

Also, you can save yourself hundreds of dollars if you use a manual boost controller. You don't need those fancy electronic ones. If you want to use a manual one, use the pressure relief valve, NOT the bleed valve. You get faster spool up with the pressure relief setup than the bleed valve! I made one for my friend's highly modified TII and it works awesome. He's using a 60-1 turbo on a ported motor and currently the boost is set for 15psi for street use. He dynoed 410 RWHP @ 18psi. Check these links if you want to make a pressure relief one yourself or would rather spend $35 for one already made.
