I think everyone would agree with me when I say I do not want to spend 1 more penny than I have to on my SHO's. FF's are not the best paid proffession in the world, and now I have a wife to support. But I have to look at the big picture. ANYONE, and I mean ANYONE can turbo their SHO for CHEAP CHEAP CHEAP. That is not under dispute here. The point I am trying to make (and have been for years) is that RELIABLE speed costs money. To do it RIGHT costs money. And if something is worth doing, it is worth doing right. My time is as precious to me as my money.

That said, I throw the gauntlet down. A true FI SHO challenge. If ANYONE can get a reliable $430whp out of their turbo SHO on the cheap, THEN DO IT! As it stands, of the 4 known dyno runs I have seen by turbo SHO's, ALL were from MY car. If someone duplicated my system down to the last vacuum line, parts alone are WAY WAY over your $2000 mark. Sure, get used parts (FWIW I would not touch an Ebay turbo with a 10ft pole, just too many variables, and the turbo is the core of the system, and they are not expensive NEW, with a warranty), pass on the Tweecer, wideband, gauges, and other supporting mods, and you could save some dough, but your system will suffer for it.

Then, add on all the supporting mods, and you are looking at some serious change. No 300+whp SHO should be running around on stock MAF, injectors, fuel pump, diff, clutch, brakes or suspension. And no FI SHO should leave the garage without a full complement of gauges. So yes, no one is disputing that you can turbo ANY car on the cheap. It is done every day. But I wanted more than a scrapped together wham bam TYM SHO. I wanted a complete package, on that stops and turns like it goes. I have that. And you can not duplicate that without dropping some cash. And I will still have a wonderfully running, EXTREMELY powerful turbo SHO years from now, with another 50k miles of trouble free enjoyment under its belt. And for that, I am willing to pay the admission price. Don't bemoan me because of that.

So please, one and all, build your turbo SHO's. Dyno them. Then drive them across the country in July to the Convention. Drag it, track it, AutoX it (and while you are at it drive in the most clutch hating city in the world - SF Cali), then drive it back across the country in July. If ANYONE does it with more HP and on the cheap, you can drive my car home to. Simple as that.

How many suporting mods do you get when purchasing a supercharger kit? With sales of standard kits such as a Mustang or a Camaro, you don't get hardly anything. That is up to the end user, what makes a turbo kit so different?

Well, SHO SHOP's kits included the MAF, LPM, injectors, fuel pump, in fact, everything you needed to SC your SHO. Even most big name kits (powerdyno, Vortech, Turbonetics) inlcude everything you will need save for spark plugs. If I were to ever offer a kit for the SHO, it would include every peice you would need, MAF, fuel system, tuning, etc. Drop car off on Monday with 220hp. Pick it up on Friday with 380hp.

Whoa!! 430hp is a **95%** increase in power. 300hp is a 36% increase in power. AFAIK, Yamaha designed the SHO engine (we're talking block, crank, ect...) with 300hp in mind...and Ford detuned it due to transmission problems, among other things. At the 300hp level, stock injectors are fine. Bring the fuel pressure up with the boost to compensate for the extra charge, and things are ok up to 7 or 8 pounds of boost (more boost than I will need). My experience is with a MSD 6 and a BTM for timing control...and I never had a problem. As far as cost is concerned...between swap meets and evil bay, I have most of my parts (the turbo if I use the T3/T4 hybrid, BOV, fuel pressure regulator, and all of my misc piping and flanges) for under $1200. That's a done deal. I chose the AT as it works better with a turbo (less drop in boost between gears), and it makes the swap worlds easier for a wagon. I still need a LPM, and I will need to fabricate my pipes and mounting brackets. No intercooler atthese low boost levels. Oh...the engine is a 7K unit....I'll check it through, but I really don't expect to have to replace much internally. 300hp at the crank should be like a walk in the park for this motor. We'll just have to see...the swap will start in late March with an estimated completion date in May (to give time to work out bugs). If if costs more than the $5k that I budgetted then I'll just have to come up with more money, but if a weak kneed 2.8 liter GM V6 can handle 10#'s of boost with the same mods that I listed for 20,000 miles with no breakdowns (regular maintenance not withstanding), then the SHO should be able to do much much more. Like I said...we'll see in March.

...and turbocharging.
Don't skimp on the maintainance...it WILL bite you in the ass. Make sure the engine is in tip top shape before you boost it and your rod bearings are new...it would be a shame to put it all together and have it last a few hundred miles before you get the dreaded knock and need another engine.

I lasted about two months with 9lbs before I got bored.

For 7-8lbs you might as well save your money/time and just go with a zex kit.

not to turn this into a maint thread but nobody ever mentions the crank bearings, i've changed my rod bearings at 199K but i think i'm going to do the crank bearings just to do them. are they not prone to failure at high milage or should i definately change them before i cram 9-12 psi down its throat.
