Hey, I had a quick question for anyone out there who has experience modifying TII's.
I have an 87 TII, that is modified in the following ways:
Has dual 3" exhaust, HKS F-Con system, Racing Beat EVC, an HKS Fuel Cut Defencer, and an HKS air filter instead of the stock airbox.
My question is: How much HP can I reasonably expect from these modifications, and what is the safe level of boost I can run at. This is taking into account that the engine in the car was replaced with a brand new, direct from Mazda engine 4,000 miles ago, and everything is functioning perfectly.
Thanks Alot for any help

 

Maybe I'm having brain issues, but what's a Racingbeat EVC?!?

 

if i am not wrong is ELECTRONIC VALVE CONTROLLER

 

with the stock fuel pump 8psi.... 220hp

with a bigger fuel pump (walbro) 12psi, 260hp

 

A Racing Beat EVC is an Electronic Vaccum controller, a boost controller in the cabin. How much do the Walbro fuel pumps run, and when i get that should i be looking into upgrading fuel injectors as well?
thanks.

 

The walbro runs like $130 or so I believe. You don't have to upgrade your injectors. But with that new engine I'd be safe and get some larger secondaries and a way to control them.

 

I would reccomend you get 680 secondaries. The walbro isnt neccesary unless you are going to be pushing over 12. Porting the wastegate is a good idea because on my car in fourth gear i can tell it will go way higher then 12. And if you get a SAFC or somthing similar that is the only way your car will not run super rich. my buddy had a 87 with 680's and he put in a walbro and it ran way too rich and it wasent as fast as it could be. Look @ my setup it works great, havent had any problems yet. I might re wire my fuel pump later on
