Just received the latest issue of Grassroots Motorsports. They have an article on junkyards and the treasure trove they contain. Here´s a bit from their article on Mazdas:

"Even though the Protege, Escort, Tracer and Sephia..share engine internals with the 1.8 liter Miata, they came with mild camshafts. Adding the Miata-spec bumpsticks can be a quick way to improve performance."

And another:

"Some mixing and matching of factory parts can also yield nice gains in the Miata´s power. Generally speaking, the most desireable parts power-wise include the 1.8 liter Miata block and crankshaft (all years are very similar and also interchange with the ones found in the 1991-95 Ford Escort GT and LXE), 2001 and up pistons (10:1 compression ratio) , and the camshafts, cylinder head and intake manifold from the 1999 and 2000 cars. These parts all bolt together and Miata enthusiast/swap master Randy Stocker of SoloMiata.com has seen the combo produce 160 horsepower and 125 lb ft of torque at the rear wheels." The article then mentions that the engine also had some headwork performed to generate these numbers.

So, you´re saying "BUT I DON´T HAVE A MIATA?!" No problem, just get the camshafts from a 1.8 liter Miata and install into your Escort GT. Also check on whether the pistons will work. I think the 1999 + Miata´s were a 2.0 liter engine so the pistons may not work. If they do, there´s instant power there to be had.

That´s the big question really - can we use the 1999+ pistons? I don´t know, don´t have the means to check really. But the camshafts are supposed to drop right in. I don´t know what performance boost they´re supposed to give, or whether it´d be worth the money, but if you can get them out of a junked Miata for some spare change, why not?

Grassroots Motorsports is really the magazine you guys should be reading if you´re interested in performance for the Escorts. Most mainstream mags cater to the Honda, Toyota, Mitsu, etc crowd and their current models. But Grassroots has everything for old and new, plus enough generic technical knowledge to apply to all vehicles. I learn something new with every issue they put out.

As far as the cams go, you can just drop them in and go. they aren´t radical enough in terms of lift to hit the pistons. However, as with any swap of parts, if it wasn´t intended exactly for your application, test it. put som clay on the piston, install the new cam and slowly use your wrench to turn the engine two ful revolutions. The valves will leave marks in the clay, which can then be cut and measure to determine piston to valve clearence.

It´s a good publication. I´ve picked a few up from the news stand, and been quite entertained (and educated of course) from their articles. :-D

Keeps getting better. They take an old Triumph Spitfire and stuff a Honda S2000 engine into it.....Man that should be a fun ride.

The Miata cams are a bit more aggressive, but should work just fine. When I did all my homework, I decided to go to WebCams and have them cut some cams for me. I sent them blanks and had them use one of their performance Miata profiles, but added a bit more duration. They work like a champ. Hell, I still have a new 99 Miata intake (as I recall) cam that I was planning on using, initially, but decided to go with the custom cuts, instead. I even have an unused Pacesetter header, a ne Ford Racing ZX2 rear sway bar, and a host of other pieces. I am about to build a garage, by the way, and some of the other old Miata and GT exhaust pieces may be on the way out.

Any idea what would provide the greater pull? The intake or exhaust cam? Or would both have to work in conjunction? I´m seriously considering heading out to the junkyard to pick up some Miata cams if the budget will allow.

Also, anybody got a white LX-style grille they´d be willing to part with for cheap (like free??!), I´ll pay shipping of course. Hit me up privately. I want to change over to the LX grille.

I´m gonna be off-list for a couple of days, refinishing my floors so the computer won´t be connected. IF I can get the job done by the weekend, will head to the yard on Saturday to see if I can´t snag a set of cams. Should be plenty of Miatas out there, far far more than a junked EGT.

Matt - I´ll let you know how much they want for a set.

If you build the engine right, it won´t know the difference between the stress levels. How about building a 9:1 compression ratio and balancing everything to spin out to 9000 rpm, then turbo that bad boy. you wanna talk about mad horsepower. Just think of what an S2000 can push out if you super/turbocharge it. it´s already pushing 246 hp N/A. :-o That would be some sweet action... :cool:

yeh but can u imagine what 11 comp pistons, aggresive cams, lightened flywheel ported and polished could do for that car....i think w/ the pistons and cams i could get to 200...with the lightened mazda speed flywheel, i would get a faster rev....... not to mention doing some timing work and stuff... i think i could go pretty goood on N/A...eps since our car only weighs 2500 pounds...

True, and you can even lighten the car up itself...rip out the seats and plastic crap around the exterior...you could get the car down to about 2200 lbs at least. :-o
