How much would the Reliability Mods cost me and what are they ...... also the 7 that i'm lookin forward on buying is a fully stock 93.

 

less than 1k.

dp
radiator
AST
hoses
boost gauge
water temp gauge
(possibly air/fuel gauge)

Shouldn't set you back too much

 

ttpowered : is this including the installation charge? or are you assuming that i'll install it myself...

 

assuming you install yourself

The guages aren't hard, the dp is not that hard if you get the m2 one, AST is very simple, radiator is not too easy, hoses are a PITA

 

DP: 150 (used) - 300 (new)
Radiator: 250 (used) - 600 (new)
Gauges [boost/water temp] 50 (used) - 300 (new)
Alum AST: 150 (new) or eliminate 30 (new)
Hoses/tie wraps: 50-100 (new)

I'd also change the fuel filter, oil/oil filter, tranny fluid, etc etc.

You really don't need a new radiator, the stock one should do just fine. But if your pockets run deep then go for it. You should also think about getting silicone vaccume hoses, the stock ones can become brittle and break over time.

 

im confused, god I hope I don't get flamed for this, but doesn't the car already have a water temperature gauge? What's wrong with it?

 

"Why do you need to add a water temp gauge when the 3rd gen RX-7 comes with one?
Because the stock gauge won't show a rise in water temp until it's very, very hot and too late."

I was told that if your not racing nor durbing on it you dont need the so called reliability mods. Just keep the fluid fresh especially the coolant and engine oil.

This was told to me by an rx7 specialist/mechanic

 

I speak from experience, getting a new radiator is just as important as a new AST. My radiator went before my AST did and it cost me dearly

Trust your mechanic all you want but if you want the car to last a long time with fewer worries then DO the "so called reliability mods". + you can't tell me you don't 'race' your car

 

No, really dont race the car anymore. I 've had it since Oct 92 and I hardly take it up anymore. The car is totally stock except for the clutch and I wish I replaced it with a stock one when it went out. I would totally do the reliability mods if my rotary mechanic told me to. But he told me I do not need to because I'm not harsh on it.

 

vented hood!

 

Radiator is an absolute must. Especially if you are buying an FD with higher mileage. The plastic top tank on the stock radiator cracks and, as everyone already knows, overheating on an RX-7 is VERY BAD. www.absoluteradiator.com is a great place to find an all-aluminum radiator; Koyo for $375, Fluidyne for $412.

You can use a mild steel downpipe (it won't last as long as a stainless steel one), and those are typically $250, new. The Autometer boost gauge should be able to be found for $100, new. Some forum members might have a extra one that they'd be willing to give away. And the silicone hoses, make sure you use some silicone sealant and tie-wrap EVERYTHING. Give yourself at least 2 weeks to fully complete the job ... and for your sake, follow the simple rule: one hose at a time.

If you're going to pay for someone to do the work, I would say let an expert do the radiator. I did that simply because I've never taken the front clip off of any car. It tagged on an extra $110 for the labor and the flush ... not too bad.

 

You gotta give those turbos some exercise!! That's what they're there for.

 

I was told that it wasn't necessary for a upgraded radiator. But either way i was planning on going for it as soon as i get a FD.

 

All the relibility mods should cost ya about 2-3k I say, well thats if you live in Hawaii and you gotta ship everything 1st or 2nd day air via USP or FexEx which pretty much nearly doubles the price of everything.
