FEMA and Hustler...I know there's a joke there somewhere.

considering I've never seen a turbo miata make it through a 30 minute session without braking a manifold/dp or overheating, its necessary.

Ok. Rather than spend 500 dollars+10 hours worth of gas and a day of your time, spend the money paying a machine shop to build your motor. Then, you can have a turbo 250whp miata to drive that won't overheat under street use. It may be susceptible to overheating during 30 minute track sessions, but you won't know until you track it. With a well designed fan shroud, good fans, a big radiator, and only an intercooler in front of the radiator, I'm betting you'll be fine. You could worry about the differential failing, so go ahead and swap in a ford setup, and worry about the transmission failing so swap in a T5 or an RX7 transmision, and worry about your windshield wipers wiping too slowly for track conditions, so go ahead and replace that too, and worry about the drain plug on the oil pan vibrating loose under certain frequencies that could be generated at certain engine loads and RPMs, so put a tach weld on the plug, or you could just quit whining, bitching, and being so ---- about everything and just turbo your damn car. I bet I'll have a custom one off twin supercharger setup running on my car before you install all the **** you already have that will bolt right up.

There is no point in dropping $200 on a track day so I can drive 5 laps and have to go home. I know you don't believe it, but every turbo car I've seen, including the handful of "turbo-sm" cars grossly overheat in 80* ambient temps.

My little 1.6's needls has never budged from 11:00, but I've driven a 99 with a koyo rad which was naturally aspirated which I got to overheat after about 5 laps in 100* heat.

drop your car of at BEGi and leave a blank check...come 2-3 months later and sign said blank check and pick up your car with the HEX or whatever system...then write it of as a business expense
DONE
except you'll be just another check book racer

WTF did you wrap the radiator in saran wrap or cover it up with cardboard? Did it have colling fans? Any water in the cooling system? I mean, the more HP you make, the more heat you have to dump. I just don't see how a NA car with a big *** radiator would overheat unless something was flat out wrong. People track their stock miata's with the 5/8 core radiator and they do fine.

You can do what you want, but my sugestion is to build your motor and bolt your turbo **** on it, and drive your car, enjoy it. << There's a reason you have your own smiley, I give up.

Pretty sure savington tracks his turbo 1.8 and he doesn't have any badass shrouding or anything. Just a nice big radiator.
I think he said he started overheating one time though, not sure what the conditions were.

Don't you have 2 1.8s?

Turbo the bitch, take it out to the track and see what the problems are...run a lower boost setting, something around 200 HP, I don't see what your obsession is w/ 250 right ******* away.

But after you get done with at least one session, you will KNOW what you need. Pick up a 94+ bottom end, build it with those nice *** parts, take the car down for two weeks or so when ready, have the 99 head worked, take 99 head, place on 94+ bottom end...built motor...address cooling issues as they arise...all while enjoying a turbocharged miata.

I've driven several turbo cars that were able to take track abuse without overheating. But, as was a point that was made earlier, you will never know exactly what your car needs untill you do it. **** breaks, the faster you go the more things are likely to break.

It's interesting how worried you are about everything breaking and still track your car. You've gotta be prepared anytime you take you car to the track that the possibility exists you might just end up leaving it's mangled corpse there.

no kidding. I turboed my first car, parted the car out, sold it. Got my 99, was about to turbo it, decided not too, pulled the trigger on race tires.

Pick one and stick with it. I say slap it it on, maybe get a smaller turbo go have fun.


And for those that say how can a stock car overheat. Come down to texas during the dog days of summer, you can over heat sitting in front of the AC.

I'm from Pascagoula, Mississippi, and I'm further South than Houston Texas. I know what hot is. I don't believe a NA miata would overheat with a 2.25" radiator short of wrapping it in saran wrap. I mean, was this a 20K dollar engine NA turning 8500 and pushing 200whp NA, I still doubt it would overheat, and if it did, it would most likely be the stock water pump cavitating, not because it's located in a state where miatas overheat.
