I'd put a keen eye on the oil pressure. I boosted a Volvo (I know, I know) with 200K on it, but didn't put in an OPG. Low idle pressure + the heat of the turboz + the pressure drop from the turboz = kilded motor and cam.

 

i'm doing it... i have about 182 right now...i don't have much miles on it yet...but doing about 12 psi....miata motors are cheap....i'll buy another one if i blow it up...unlike honda...their motor are in the gs...heheh...

 

Under full throttle and full boost we watch our oil pressure bounce between 20 - 80psi rapidly when the engine passes about 5700rpm.. That 206,000 mile motor has a newly re manufactured oil pump with around 100,000 miles on it now.. I blame the oil problem on the fact that the pump came from parts America.



hahahaha. Between the two of us we've got 4 spare motors..

 

Boosted mine at about 145k. Been running ~7lbs for a few thousand miles with no problems.

Well one problem....I keep wanting to turn the boost up.

 

mine is at -15 psi and i still only barely keep the POS running, you lucky bastards

 

Does someone have either the Greddy or the Begi S kit install instructions they could post up or email me? I'd like to see how difficult of an install it's going to be. I'm just a little confused as to where/how I attach the oil feed/return lines, and if the block has to be drilled and tapped. I think I am confusing myself with everything I have read on honda-tech.com from when I had my '88civic hatch I was going to boost it the DIY way.....

 

That rapid bouncing could be detonation. Try pulling a little timing around that area

 

this is what i used to install my turbo kit..i used the instruction from flying miata..see if it will help you.

Good lookin out. Time to get me read on!
