What kind of EFI are you running?

If it's the stock ranger set up, you're running on borrowed time. If you modified the MAF and have 19's, I'd still be scared of anything more than 5 psi. If you are running the turbo electronics and fuel injectors, I would guess you could run 8-10 PSI. Just be super careful and listen for detonation. The stock pistons simply will not withstand detonation while under boost. Anything over 10 I'd be too scared to try because if the A/F gets off even slightly, the pistons will be toast.

It depends on whether or not you will port the intake and heads. If you do that and the engine flows a greater CFM then you will max out at a slightly lower PSI. If you flow 300CFm your turbo could push 5PSI through the engine. However if you bump it up You will achieve greater power with Less boost. An engine that pushes 450CFM will claim the same Horsepower as the 300 but at 3.5 PSI. Its a basic desription but something to think about.

My personal recommendation is take the heads and intake to a good machine shop. Have them ported, portmatched, polished etc. (Dont over do it) Then when you put your turbo on the truck start with a lower PSI. But no matter what you should be able to push 4-5PSI safely. Anything more needs to be done step by step on a dyno tuning while increasing. Otherwise your subscribing to the big bang theory.

Also go find an '84-85 SVO Mustang motor, I dont know about the '94, but some years are a complete match for the crank and pistons.

I've run 5 psi on stock pistons for a long time without trouble. I still have good compression on this engine, too!

just push 15psi then when everything blows you have an excuse to rebuild the bottom end. make sure and report back with what psi everything let go....lol

most everything i have ever seen is 6-7 psi on stock internals. certain engines get away with more some cant handle that.

when you push 30 psi thru it post the youtube video of the head gasket blowing/head blowing up/piston through the oil pan, i wanna see destruction!!! honestly tho, even a supra twin turbo w/ thicker cylinder sleeves and forged internals cannot go above 22 psi w/o rebuilding it every 5 wide open throttle runs, i doubt seriously that a stock ford block could take that much psi. after completely rebuilding the internals and have everything setup for large boost i wouldnt go above 20 psi. stock internals i wouldnt go above 8 for durability, the 10-12 psi guys will be rebuilding real soon i can almost promise you that.

The stock ford 2.3 turbo block is well proven to endure 20 psi for well over 200,000 miles and then it's usually the top end that finally throws in the towel. Currently, my 35 lb/hr injectors are pretty maxed out at 16-17 psi. My next step is a tuning setup and bigger injectors. Then I can join the 20 psi crowd.

With an upgraded bottom end, E85 and/or methanol injection, and a good tune, 30 psi is doable.

But on a ranger bottom end with cast pistons (rods and crank are the same a stock turbo motor) definately keep the boost low.

why e85? it is thinner and contains less potential energy, you use twice the e85 to produce the same amount of power as gasoline, plus at the price its just not cost effective. i was reading thru a flex fuel vehicle owners manual and it clearly stated that you will have to go thru two tanks of e85 to get the same mileage as a single tank of gas to get the same mileage. methanol on the other hand is hardcore stuff, treat that w/ respect or youll be rebuilding an engine in a hurry. that and i doubt seriously he wants to spend 7 dollars a gallon to fill up cuz he cant just put regular gas in the trk after tuning it for methanol. if this is a daily driver or show vehicle id stick to regular gas as its readily available anywhere and is cheaper/more cost effective. if you are trailering it to the track and are running it for timeslips go w/ methanol, but i wouldnt even think about putting it on the street cuz youd be stuck at the house siphoning gas every time you got low. just something to consider and my .02
