I just reached out to Extrude Hone AFM located in Paramount, CA to get a quote on my Trick Flow Twisted Wedge upper and lower intake. $750. That seems like a lot of money to get another 100 CFM out of an already good flowing intake. I suspect the horsepower gain is maybe 20? On a stock SBF 302 will the extrude hone process disrupt the balance engineered into the packaged HCI? I realize a tune will likely be required, but I don't want to spend the money only to have the car fall flat on its face below 3000 rpm.

Boost... it will fix any potential current or future issue with it falling on its face

Just read your entire thread. Great work.. I love the car. Very informative as well :nice:

Quick question - why would the car fall flat on its face under 3k rpm?

I'm not saying it will, I'm questioning if extrude honing the intake but leaving the heads alone for now would affect the existing torque and horsepower curve. But back to your question, if you were to add a 80mm throttle body to an otherwise stock fox body 5.0 it would REALLY affect the driveability. That's my concern.

Just called Trick Flow (TF) as I'm doing some research on my engine combo. If you have TF heads, but aren't sure which ones...here's the cipher.

"-1" or "1X" under your valve covers: 170cc

"-2" or "2X" under your valve covers: R head

"-3" or "3X" under your valve covers: hi port

"-4" under your valve covers: old 190

The stamp on the front, see photo, means nothing in regards to size.

Think I found why my car has been so finicky while driving around in 95+ degree weather. Electric fan control module fuse literally melted. Called Derale and they suggested replacing the 30amp fuse with a self resetting circuit breaker. Done!

BTW, removing ALL your A/C components is good for 33.2 pounds which is nearly the weight savings of a MM k member.

Did you know only 16 bolts hold your front bumper in place? And 4 of those are really for the lower air dam. Keep wrenchin'.

I'm attempting to install a new Sony double din radio into my '93. I've followed the instructions and have power, but no sound. I've attempted to research the Sony radio to blue amp wire schematic, but I cant find the right layout. I've even pulled one of the speakers to look at the wires which of course are correct, but I cant figure how to wire the radio up to the eight blue amp cord wires.

The "1988 Mustang Electrical & Vacumm Trouble-Shooting Manual" was helpful with power, but not speakers and I cant find anything on Stangnet.

This is all wrong. You should have bought a wiring installation kit. It would come with a black and a gray connector that would easily wire to the radio by color....and plug into the factory wiring with no cutting.

Can you do a quick search and point me in the direction of one on Amazon or something?

You want something like this

You are trying to wire the radio in series after the amp. The 93 Amp is only 80w, which is prob equal to what the head unit itself can do, so you want to bypass it. If you reach up into the radio hole, you'll see the other connections for the amp. Unplug those connections and plug the linked harness into the male end of the harness and connect that direct to the radio

Ok. I see it now. It's literally behind the HVAC controls. So I buy the Metra adapter and plug into those and then wire the gray and black adapters (on the plain wire side) into the radio. And this removes the amp from the equation?

Yup. Amp at that point is just excess weight. Sell them on ebay as they go for decent cash, however the cut up harness will be a negative.

I actually just bought a amp/harness on ebay for $50 that was cut just like that and repaired it. I'll likely flip it back on Ebay for $100-150 once I test it.

Excellent. Big thanks. Adapter is on order with expected delivery tomorrow.

Great tip on the Metra 70-1770 adapter. Worked perfectly. Wires were colored coded and I even improved my soldering skills. Stereo sounds outstanding through the original "performance speakers". I was actually considering buying replacement speakers, but no need. Thanks again 5L5!
