it seems most guys have the SOHC 4.0 but I think it would be good to put together a engine mod guide for the OHV guys. anyone got anything the want to add?

 

cut the airbox open? haha


i havn't really touched my engine, upgrade wise

 

not that I would be doing an engine swap anytime in the near future. but I was thinking alot about them, when I thought how it would be cool to be able to build and keep the 4.0 OHV instead. Thought it would be cool to start a guide for us OHV guys.

Stuff like Heads, Headers, chips, Superchargers. anything that would help.

 

yea it would, when this one dies, i plan on swapping a new one in and rebuilding the old one..

lets see what kinds of stuff people can get into this thread. There is just a ton more for the SOHC because of the mustangs

 

My 4.0 OHV mod list:

- UPD
- Screamin Demon
- K&N drop in filter
- efan
- Dynomax cat-back

There is quite a bit of stuff that can be done to the 4.0 OHV.....

For instance:
- 410 Comp Cam (more agressive than stock)
- 422 Comp Cam (more agressive than the 410)
- Morana 4.5L stroker kit ( http://www.moranav6racing.com/catego...?CategoryID=32 )
- port and polish heads
- headers (JBA prefered for the 4.0)
- high or lower compression pistons (depending if you wanted to add turbo/supercharger)


when my engine goes, it will be stroked to the 4.5L with a 422 Comp Cam......i couldn't imaging haveing .1L less than a 4.6 v8 in a v6.....me personally i would rather do the stroker kit than drop a v8 in.....easier, and you would have a sleeper.....pop the hood an NO ONE would know....

 

This would be awesome! I have my old 4.0 sitting in my garage all apart waiting for some cash to start rebuilding it. My heads are getting done first. In the mean time I'm painting a few things like the oil pan and valve covers and some other odds and ends.

 

hmm cams, heads and a S/C would really wake my OHV up....

 

i have done my research on the 4.0 OHV......the stroker kit will put the engine at roughly 260-290HP.....that according to Morana......

i don't want a supercharger....

this will be my setup when my engine goes:
- Morana 4.5L stroker kit
- Comp Cam 422 cam
- port and polish heads
- ARP bolts throughout
- UDP
- efan
- K&N intake
- JBA stainless headers
- JBA exhaust
- Screamin' Demon coil pack

i figure that will run me roughly $3500 to do since i will do most of the work myself, except for the port and polish....and i already have the UDP, efan, and Screamin' Demon......

 

My buddies 97

 

that is a sweet setup for that type of supercharger.....that took a lot of custom work cause i doubt that is a kit....

how much boost is he running and what else does he have done to the engine?

for a Ranger, i think that style is too much....a roots style is much better and takes up less room.....

 

what does it matter about room, if it fits?

 

the last time he updated his website
Performance Modifications

* Full 3" Exhaust System
o Catco 9000 Series Universal Cat
o Flowmaster 30 Series Street/Strip Muffler
* JBA Ceramic Coated Headers
* 66mm BBK Throttle Body
* Hurst Short Throw Shifter
* 75mm Pro-M Mass Airflow Sensor
* K&N Fuel Injection Performance Kit
* Street Smart Design Intake Tube
* Vortech V2 Supercharger
o Vortech Maxflow Racing Bypass Valve
o Vortech 2.62" Charger Pulley
o Vortech 94-00 V6 Mustang Intake Tube
* BBK 190lph in-tank Fuel Pump
* 36lbs/hr Fuel Injectors
* Stage III Heads
* Dyno tuned by Fordchip.com
* Electric Fan
* 4.0 Performance Adjustable Engine Link

So it was a stock vortech ranger kit, that he added the Bypass Valve and then swaped to a mustang intake setup and relocated the battery to his bed.

^^there is a lot of good reading there IF you want to run a supercharger...

 

You guys are making me antsy to start rebuilding mine! My wife will be coming after you all if I do start it now. She wants the bathroom done first.

 

you know, this is really the only thing that i wonder about when i buy my next ranger. Would i want the 4.0 OHV in the earlier '00 and down or an 01 with the sohc?? i mean i rather find a cheaper gen 3 or something with the 4.0 ohv in it then having to buy a 01+ with the sohc in it. im just not really sure. id like to find a 97-98-99 ranger for a decent price with the ohv. But i mean are they really that powerful? and how are they compared to a 3.0? i know my 3.0 in my 94 was a dog but overall nice truck which sometimes regret trading.

 

I didnt like the SOHC. I like my OHV alot more. I didnt like the RPM range with the SOHC.

 

the OHV is a good engine for low end power....

i'll sell you mine......already got a few performance mods on the engine.....

 

yo man id buy your truck in a hot second but i dont have the money at the moment. I like your truck a lot too and its too bad i didnt have the money. so i mean how fast does it take to get to 0-60?

 

dunno never timed it.....it gets there pretty quick....

PM me if you are interested, we can talk.....

 

Well I have...
From the Cat Back exhaust..Borla Pro XS
K&N FIPK Intake
Bamachips XCAL2
and..the 66mm Throttle body..
What else can I do??
Im thinkin either E-fan, or the coil pack...
What would give me the best result? I always thought the underdrive pulley system would be sweet but im not too sure how it works

 

you can do both of those mods for a bolt on mod.....or you can get into a number of things with internal engine parts......cam's is one way.....on a base stock engine, you can get a 410 Comp Cam camshaft and new pushrods and be set....that would add a little more low end torque....

i recommend 100% an efan AND a Screamin' Demon coil pack.....IF you get an efan, get an efan from a '94-'95 Ford Taurus.....it fits the radiator perfectly (with some minor trimming of the shroud) and has a fan shroud that covers the entire radiator.....grab yourself an efan controller from Summit for $50 and install it......use the high side of the Taurus efan (has 2 speeds) (the high side is the black/yellow wire)......you can feel the fan sucking air through the radiator from the front......it is probably the smartest thing i did.....

the UDP minimuizes the amount of turns the engine has to turn to turn the accessories (alternator, a/c pump, water pump, power steering pump)......it gets rid of some strain on the engine allowing it to send more horsepower through to the ground....i have one and recommend it to anyone....

 

How about the crank underdrive pulleys (harmonic balancer together)? Not hardcore, but something some guys could do for bolt-on performance...

 

that is what i was refering to when i say UDP (under drive pulley)......

 

I'll second that one, I'll drive my brothers '99 Explorer every now and then, and its got some power with that magnaflo cat back and intake, his intakes is wierd, looks NOTHING like the regular SOHC's. granted its on 20's, w/o any gear work, so i try not to rail on it. it sounds good, the Intake is loud as hell too haha, but i prefer my OHV in my ninty foe!

I've been contemplating selling my truck for an SVT Contour or an Exploder. But sometimes i just want to keep it and rebuild the motor and make it quick. but from what i've heard, the SOHC's were better, but the OHV's were stronger, boosting wise or something.
