Im sure you can call and have them assemble you a kit while on the phone the parts shown there would set you up for anything later down the road you may want to do such as run 20psi of boost and turn at 3900rpm and run 1300egt and such

you want it to last don't you? get regular parts, run 12-15 psi, keep the EGT's as far under 1200 as possible. DO NOT REV IT TO 3900 rpm! good god thats asking for problems! the engine revving that high is just wow stupid. the revving has to do with the rotating force as well as the parts holding it together. there
s a reason it hits the yellow line at 3 and redlines at 3500

trying to build a performance engine out of one a these won't be as reliable as a stock rebuild no matter what anyone says.

Ya, the governor should keep it below 3,500K so no worries of going that high.

just put all the parts needed in a shopping cart, since they didnt have a premade kit. the total was 2300$ after shipping. All the parts say "performance" but really what does that mean. Im thinking they are probably same specs but with the hypermax name then that must add the performace part to it. correct me if im wrong

i wouldn't doubt it one bit that they are of the exact same quality as international made parts just with another name. name ads a 25+% price increase ya know...... 1500 (international) vs 2300 (hypermax)

Ive asked a few guys on facebook that have the hypermax parts in there motors and they all told me that no the hypermax pistons withstood way more temps and were lowered compression,and they said the wrist pins were very heavy compared to what they pulled im not saying go with it but thats what the 2 guys i spoke to said and i got no reason to doubt them i mean think hypermax couldnt just make the same parts as international then people run them as high performance like they were told and they break and then hypermax gets in trouble for false advertising just my 02

since this is my first rebuild ever i think i will just stick with the stock internals, if i was willing to really try and push power and torque then i wouldnt of lifted it lol maybe in the future i will do a performance build...but for now just the ford or international replacement will do

glad to see you stay on the side of consistent reliability 91! just because were young (20's) doesn't mean everything has to be super fast and who's got the fastest blah blah blah im young to and i chose reliability over speed. when my rebuild comes it will get a international kit. maybe head studs. depending on financing, not necessary for performance but for the fact studs don't ever really stretch and its better for the longevity of the head gaskets. and the stock ford turbo system.

here's to another 20 years of reliable IDI service

i know what you mean i just don't like the idi of shaving the pistons down to some crazy low compression the engine wasn't designed for and revving it super high all the time and expecting anything to last a turbo system designed to get more power out of a basically stock setup is one thing trying to crank amazing power out of one a these when it was designed as a workhorse and not a speed demon and destroying a good truck is another

Im using dave as a example power and dependibility both you just have to do it right and go through every detail to make them go hand in hand and i imagine if dave had these hypermax parts his motor may even be able to bring more hp to life still staying dependable its all about the build method. Sure i could shoot a lot of nos into my intake and make one run at 300hp but it would blow or you could take 2yrs getting it all right and fine tunned to make 300hp and have a dailydriver that had no troubles.

I don't call myself a speed demon, but I don't drive like a grandma, once I calculate fuel mileage I will probably start, lol. Thats why I'm putting it off.

then there is that too lol i get 18+ MPG outta my truck cruising at 65 unloaded with my bone stock N/A 7.3 and that is my number 1 reason for leaving my fuel screw and such alone. the fuel price is to high to try and increase performance as well. i'd love to have my turbo on to increase my MPG towing and thats my number 1 reason for wanting the turbo.
