This is all you will need, as far as special hardware is concerned. An original equipment oil pump would be my first choice. It is very important that you do NOT use a high volume oil pump in your rebuild if you do it will most likely lead to the destruction of your aux shaft and distributor gear, as well as your engine. If you guys want to build a perfect, bullit proof motor, then I can make some suggestions, based on science and 20+ years of engine building/ machining and racing experience. 2.3L turbo engines, are strong enough to withstand a 350 HP level, so other than a normal rebuild with forged pistons, I would only suggest a windage tray and some ARP rod bolts as added insurance. 425” of gross lift require the use of stiffer valve springs, which you should keep in mind if you’re on a budget.425" of lift is more than enough to reach a 250 HP goal. There are dozens of cam grinds available. A high flow catalytic converter and a 2.5 or 3” diameter cat back exhaust would also be a good idea, for reaching 250 HP.Ī camshaft swap would be the next item on my list. You need to check your state emission laws regarding these, before you start swapping out parts. Several companies sell bolt on down pipes for your car, click link->( 2.3T Downpipes) which not only increase HP, but improve your boost response as well. Increasing the exhaust pipe diameter coming from the turbo makes a big difference. The Exhaust system would be next on the list of things to improve. To solidify the fuel system, I would suggest the installation of a 255 liter per hour fuel pump as well. A better solution is to buy a Moates ¼ horse tuner, so you can tune the entire system, which is really the key to making more power. An "LA2 or LA3 ECU" from an 88-89 Thunderbird Turbo Coupe, along with the T-bird Vane Air Meter (VAM) can be made to work with the larger injectors if you adjust the VAM.
These will work with slightly larger injectors installed. Several Ford 2.3L turbo models came from the factory with ECU’s which were calibrated for larger 36# injectors. 30 lb per hour injectors will support about 180 HP, so if you are looking for 250 HP you will want larger 42-45 lb per hr injectors, which won’t work very well with your stock ECU. The 84' GT turbos had 24 and 30# per hour fuel injectors from the factory. The fuel system is the first limiting factor that you should address, since the available HP of your engine is determined by the fuel injector quantity. 250 HP is possible with a mostly stock engine, but you need to cover a few basics first. This all comes down to money, time and how much you want to do yourself.
