4.0 OHV Turbonetics

[nooberiffic]

A friend of mine from the Army has a hookup with Turbonetics and Vortec. A serious hookup.
I have a 2.9L and am in the middle of the D35 and Exploder 8.8 upgrade, and further back on the list I have a 4.0 OHV from a 93 explorer with some blown headgaskets. I had planned on slowly rebuilding the motor over the next year or so and then putting it in, as my 2.9 is competely rebuilt with only 14,000 miles on it.
I told my buddy its for a ford 4.0 V6 OHV from a 93 explorer, in a 1990 Ranger. He is going to call me back tomorrow with some recomendations.
Well, with an offer like I got I cant turn it down and now I am planning on putting the turbo in the build.
What do I need to make this a safe and reliable build? What turbonetics turbo and spearco intercooler should I choose? Im not planning on running much boost, as its my off road and daily driver.
Any suggestions?

I don't know anything about turbonetics brand.
other than the direct drive turbine engines 750hp to axle in the late 60's. have a link?
Vortec would probably come with a top-end kit though wouldn't it?

I know they are fairly active in the import crowd.

Get you a slightly smaller turbo than what the engine size is, something Equivalent to a T3, or T3/T4 hybrid, around a .60 trim is what your looking for, as for IC, the biggest you can fit in your truck

...

For a 4.0L, I would go with a straight T4. Probably something like a .60 to .70 or so A/R compressor housing and like a .80 or so on the turbine housing. I'd do either and "S" housing on the compressor or at least an "E". If you need more help sizing it, shoot me a message. Turbonetics compressor maps are all over the place, and I can size it for you, if you'd like.

I would use a regular t3 .60 exhaust housing. You will explode a 4.0 with a t4.

You won't explode the 4.0L, there's guy's on here running 20+ psi boost to stock internals...You don't want high rpm boost either, think of your application, 4x4, you don't want boost coming on at 2500 rpm (T4 .70 + trim), you want low rpm boost, low rpm boost = small turbo housing. If you are familiar with the Thunderbird TC's (turbo coupe), they ran a garret T3, or an IHI turbo, depending on year, 87-88 TC's ran the IHI, 2 of these IHI's have prven to be very well with the 4x4 crowd, excelent boost down low, right off idle, and more low end grunt then you can hang onto...If your stuck on turbonetics, I'd have your guy match their turbo with an equivalent of two IHI's from a Tbird TC

Turbonetics is definitely a rebutable brand.

A T4 would be way too big for a 4x4 4.0. If it were an all out race motor, yeah, maybe a T4 exhaust housing would be the way to go, but for what you are doing, go T3.

hold on hold on...you can put a t4 or t3 footprint on any compressor, the size of you compressor wheel is the tricky part, too small-way to fast of a spool, to large-too laggy...the exhaust footprint doesn't make it a time bomb as you guys have described...you can get a larger turbo with a smaller AR on the turbine to increase spool in thus better effinciency at lower boost numbers

your AR- the measurement between the compressor/turbine wheel from the housing, wich will also effect the spool characteristics...the father away the wheel is from the housing the higher rpm it will spool, the larger the wheel, the heavier, slows down spool(aplies to both compressor and turbine)

you can get very large turbo's with t3 footprints(my street car 200sx se-r has a T3-67HO-67mm compressor wheel/.70AR...t3 p trim .82ar exhaust)(race car sentra se-r has a t4/67 blowzilla...67mm compressor wheel/.70 ar...t4 p trim .84ar) both good for 700+
both are garrett

the t3 spools around 3k(weight of the compressor wheel) and full at about 4400-4700
the t4 spools around 3.8k(bigger exhaust and ar) and full around 5k...and when they come on holy, hold onto your shorts, LOL...best bet and bang for the buck would be the HIFI t60-1 t4 with a 68 or 63 ar mabey even something smaller, will have a standard 5 bolt dishcarge, 4" inlet 2.5" oulet, the options are almost endlest...i have a turbonetics dealer catalog if you want i will send it to you( i am a dealer)

this is what i would get

I have never read about anyone on here running 20+ psi on stock internals. I would get you a ebay chinese t3, run an ebay intercooler for a metal catcher incase the turbo blows up. I would keep it under 10psi even with it tuned. I would like to see these 20+psi 4.0 ohv trucks....
