I'm going to rebuild the 2.3 in my 87 TurboCoupe and I want to know what the best parts to use and everything I'll need to replace. I'm looking for about 280hp and 330ft-lbs. I want to build it as a strong street car mostly. If I finish the car I'd love to take it to Road Atlanta.

Oh joy, that's alotta post you're asking for. I'd go with a quality set of forged pistons/moly rings, good bearings, ARP main and head studs, ARP rod bolts, and of course have the whole thing internally balanced. Do some port work, especially on the intakes and E6, run a ranger roller and a boost valve. 3" exhaust and a K&N cone on a .48 T3 should do it.

Aerobird, what do you consider a "Quality" set? Any particular brands for the pistons?

For pistons, go with known names, such as Sealed Power, JE, Wiseco, Venolia, Diamond, etc. Bearings go with Mahle, gaskets Fel-Pro.

And thunderchicken, Layla has about 335HP and alot more porting and a much more aggressive cam and the .63 still has boost lag until about 3500 RPM and would lag alot more on a 280HP motor. I'd stick with a .48 as he's leaning towards good drivability.

Why are you going to rebuild it? Does it have any problems? A completly stock motor can put up with alot more power than you are looking for. These motors last for alot of miles and if there are no problems with your motor now there is no reason to do anything to the bottom end. The head gasket and valve seals would be a good place to start on an older motor. I like the 1035 felpro gasket but even a stock replacment head gasket will hold well over 280 hp. Replacing the cam with a roller cam is also a good idea. A stock ranger roller cam is a good street cam and can make the power you want with enough boost. The cam shaft is one of the common wear parts on the 2.3 but with a roller there is about no wear so a used ranger roller is a no brainer. I have heard of alot more problems from rebuilt motors than from high milage/junk yard motors. If it ain't broke don't fix it. It will take 20+ psi.

AerobirdMotorsports we are talking 280 hp here The stock stuff will hold up forever at that power level there is no reason to put any money into studs or anything else aftermarket for the motor. If you want to waste money shure but you can have alot more power if you put money into the turbo, intercooler, fuel system and porting.
1988 TC stock for now
1980 Capri RS turbo 11.42@120 broken

All of the stock bolts are torque-to-yield and Ford replacements are almost as expensive as the ARP stuff, so you might as well use it.

TTY? I don't think so. IOW, no.

OEM bolts were not TTY. The replacement 6 point head bolts are.

Exactly. If you have any bolt problems, the replacements are all TTY (yes even the mains, I have a set if anybody desires, and they don't come with the 1 studded one for the oil pump either) and expensive, might as well get the good stuff. Rod bolts are a no-brainer. I've rebuilt 5 of these now, and only had enough "good" bolts come out of them to do 3 with the originals. Everything from 100K auto blocks to 250K 5-Speed hammered-on blocks. The higher wear, etc. co-incides with the use and abuse.
