You really only need a few sensors to make this all work. Note the ECT sensor. there are two available aftermarket. one has a plastic tip covering the sensor and the other is brass... take the brass only, accept no substitutes. ( 99 percent of the time if your turbo car is running like crap at random this is the culprit) and it is not a cheap or easy sensor to be replacing. this sensor is located between 2 and 3 on the lower intake and is different from the temp sensor that runs the gauge. Dont bother with the boost control solenoid as it is junk anyways and i will forward you info on making your own manual boost controller that will let you crank er up to where you want if ya like. there are a few other items you can skip too, like the overboost buzzer and the knock sensor. (you will be disconnecting it anyways to get more power) you will need a distributor. go reman. it will come with a new tfi and the shaft bushings will be tight. you will need to adapt the tps from the stock tb to whichever one you go with. also ensure if you buy new they give you a bap sensor not a map sensor. they appear identical except the bap has a little filter thingy on the port opening where the map has a port to plumb it to the intake.
spend the dime and get the head magnafluxed. early heads (even up to the 86) are notorious for cracking in the chambers between the valves. 87-88 motors have hardened seats and are not nearly as crack prone. if you are doing a motor build anyways go down to the local boneyard and scoop a ranger cam and roller followers. more jam and less chance of scrubbing a lobe (common on non roller flat tappets.) if it isn't cracked pay the piper and get hardened seats installed. if it is cracked find an 87-88 head. not a service part as they are different and junk. you ma have to go in for a couple extra bucks to put in dished forged slugs if this is the case. ( or run 100low lead if it is not a daily.)
make sure you get the right pcv valve. available only from ford. all the generic ones listed are wrong and they typically leak under boost. allowing the crankcase to see pressure = bad
Now on the making power front. If you have the bucks send your head to the guys at boport for the baddest porting job on the planet
I'm pretty decent with the eecIV and happy to answer questions or help out. just post or pm me
read everything you can here
http://www.rothfam.com/svo/index.asp and check ou t the reference documents link. he has several evtm (electrical vacum troubleshootin
g manuals) covering different years and many other goodies once you start to grasp the internal operation of the voodoo box. oldfuelinjecti
on will cover the basics for sure
piecing one together is not always easy.... Good luck.
