My dad said to him, "Gee there must have been some warning before the failure, perhaps a loud knocking sound." Dude responded with "Yeah there was." "What did you do?" my dad asked. The reply was, "So I turned the radio up." That's when his wife slugged him. Funniest **** ever.

lol. I had an xgf who used this logic. She totally destroyed a chrysler sebring in less than 2 years. Wrecked it numerous times, curbed int constantly, broke interior plastics, didn't even take it to the dealer for free oil changes, just drove it on (ballpark) 3 oil changes in 2 years. I felt bad for that car.

i've had both a 1g dsm and a 2g dsm, 7.8 vs. 8.5, more of a difference than you're agonizing about and really there's not much of a difference. seriously though with the gearing in the miata you won't have any issues keeping the 2860 on the boil. with good tuning and you're motor you'd probably have 12psi by 4000rpm with 5:1 pistons

Ask Jason Cuadra. He swapped out his stock 2000 motor (9.5:1?) for an 8.2:1 GTX 1.8 courtesy of Jay Kavanaugh (you know, father of the disco potato...) and with his own home-brew cylinder head work he GAINED spool.

Course he has the FM SBB (2554) so I'm not sure what more spool really means there.

I just jumped on the deal for the pistons *shrug*

with these little baby dick turbos, i wouldn't think spool would be an issue.. spool it, and crank the boost..

Wait the Evo 9's are ever out of Boost? Only if the owner is retarded and dont have Meth Injection. Both my friends Evo 8 and Evo 9 have MBC + Wb02 + Flash tune by Jester + Meth Injection = no matter what RPM they stomp on the gas and your pushed back into your seat like a mother... I dont know the hell your talking about when you say the Evo's suck ***** out of boost due to the fact the only way to keep them out of boost is to baby the garbage out of them.

And if you have the $$$$ to own a evo and **** spend the extra like 2k to get a wideband a MBC a quick tune and some meth injection and if you don't you shouldn't be driving an Evo.

What the **** are you going to be doing with the car that requires you know when boost hits, down to a 200-300 RPM range...

Its a track toy, not a god damn race car. right? These are small, rather little turbos...this is borderline obsessive paranoia. I could understand fearing blowing your **** up, thats not a fun thing, but obsessing over little **** like this? wtf?

I want to build this ****** so bad. I've learned a lot from all the research and annoying questions. I'm still super worried about cooling in 100* on the track considering all the turbo race cars suffer from cooling problems. The supercharged cars don't for some reason. I'm thinking about getting a spare hood and cutting it up to suck air off the radiator, and a vent over the turbo.

You could always have a tune to run WI also to help keep intake temps down. Then work on custom underpans to keep flow up

water temp is my concern, not IAT. Hopefully the BEGi scooper does the trick...if I can manage to not rip it off the first time I throw the car off the track...which is about once per track day.
