Adam, did you do all the exhaust and intake port work yourself?
Or had a shop do it?

Also, what specifically did you do to raise the fuel pressure to 45 lbs?

Did you also do the MAF thing refered to in ?

I've really enjoyed this buildup over that last year or so. Nice work.

Ho John,

I did all of the exhaust work myself, since they wanted $300 to weld the JBA output to the
input of the catalytic convertor. No way man!! I even extracted the eight frozen bolts
myself, taking two days and a few reverse threaded drill bits.

Port work was done at a local Pro-Ford shop that understands honda whipping performance.
There were actually a couple of shops that were into the big tip syndrome that the imports
are in to right now. Sheesh.

Get teh buick fuel pressure regulator that looks *almost* identical to the stock ford one.
The lower O ring on the buick regulator needs to be replaced with a slightly smaller one,
like used on the stock ford regulator. I know there is a better way to do this, but I just
cleaned and swapped the o rings. Result, perfect fit!!

At the same time, I replaced both fuel filters on the bronco, there are two of them!! I
also replaced the high pressure pump with a brand new one, since it burned up a relay and
fuseable link and was making odd clicking noises.

No, I have not. I found out about taht after I had my computer reprogammed for $300, so I
didn't see why I should spring for a new computer and sensors to try something different.

Pat Kunz 2.9 are nearly identical, except his is "bluer". Mine has only the water pumnp
painted. It's going to come off real soon when I have to get to that timing chain.

He doesn't have a cam that I know of, so we will have to see what is what after I get mine
in. He does tale his a lot higher than I do, though. I think he revs to 6800 rpm without
problems, but once he went to 8000 rpm and that cost him a ticking lifter.

Once I had a TPS jam the throttle at wide open, and I stupidly took it out of gear for a
few seconds. I think the RPM guage pegged at 8000 RPM for a little while, but I had no
casualties. ;-)

The only time the engine has ever been above 3000 RPM. Lousy TPS sensors....
