87 TII: Exhaust, FCD, Intake now what?
I have an 87 TII with a full racing beat turbo exhaust, RB FCD and Im getting an intake that bolts onto the air flow sensor part tomorrow. I heard that with my current set up I might detonate sometimes which is bad, and I plan on upgrading my fuel system next. Im just learning about Rx-7s so if someone could tell me what parts are needed to upgrade my fuel system and how much it costs for each part, also the order in which I should buy them. Also is a blow off valve a good thing to add to a TII?

Next you need to retard your timing 5 degrees, then some GSLSE secondaries, then turn the boost up to around 11 psi. After that you need a Super AFC, 3rd gen fuel pump, then a Turbo upgrade. You will be set to run 12's if you can drive and you have a healthy engine

You already have a blow off valve Mazda calls it a pressure relief valve and it vents back into the intake after the air flow meter.

simply put..
DEFINATELY get an aftermarket boost gauge and a walbro, if you're feeling spicy, some bigger secondaries.. but you're also gonna need either an ecu reprogram or a s-afc if you're gonna boost that high.. i.e. over 10 psi
If you're getting an aftermarket intake, PORT THE WASTEGATE and then get/make a manual boost controller to get the boost where you want it.. don't go over 11-12 psi.
Forget about the aftermarket BOV, no good to you.. if you really want the sound, just perform the DIY BOV mod.
if you want your engine to last for the future upgrades take these precautions..
good luck.

Alot of us are in the same boat, I have opted to put my stock air box back on since I have installed my down pipe /w full exhaust, so I don't overboost and detinate, with my cone on I hit 9 psi with the box I'm at a safe 7 psi..

You are all talking about full exhasts and downpipes, and how all these made you boost around 11-12psi. So how come my catback and intake (and rebuilt turbo ) made me boost almost 14psi ?
.......trying of course not to press down too hard on the gas pedal, until I can get my pump, injectors and program

Someone was telling me about this...what is the valve called that you bought?
yes I realize this post is 3 months old...I was searching for manual boost controllers and decided to answer this.
