4.2L Stroker
 

OK, so my girlfriend has an 01 V6 that is completely stock and she wants more power out of. One option I've been looking into a lot is a 4.2L stroker kit. Esentially, it's a Ford Ranger 4.2 crankshaft, since their pretty much the same block. Anyone considering this, Anyone with tech knowledge, anyone who's done this please help. I've done limited research, don't know my 4.2 specs, how easy things interchange and what not. All help, input, questions are appreciated.

Teal beast will know, but why not get a s/c?

It is the v6 f150 that has the 4.2l, not the ranger, i believe the ranger has the 4.0l SOHC (like the 05 v6mustang)

I believe if you want to just get the displacement, all you have to do is toss a crank from a f150 into her and that'll get the job done, although without other supporting mods it might or might not be worth it to you.

I think going from 3.8 ->4.2 on a stock engine generally just nets you some more tq, not that much more hp

if you just want a few more hp, then you can do an hpipe catback etc, just basic bolt ons, if you want to start getting into real hp, i sudjest going straight to a blower. Most of them are very easy to install and make a ton of power.

Let me know if you need any more info, the possiblities are endless, and it all depends on what you want out of the car.

I Believe your right about the F150. I haven't read the article in awhile, so good looking out. I understand the added stroke displacement is only good for extra torque, but supersixmotorsports.com offers, heads, cams, and p/p intakes for the 3.8, I've also been looking at CIA, u/d pulleys, and different exhaust options. I found out today that a crossover isn't neccessary in the V6, so headers, mufflers, and take it to an exhaust shop seems like a powerfull and affordable option. If anyone checks out super six, they have 4.2 stroker kits, 4.3 long rod kits, forged rods and various compression forged pistions. This is her daily driven and only car, so I'm not comfortable with the stress of forced induction or nitrous, but I know a 4.3 can make over 400HP NA, and she wants "over 200 at the wheels". I think a T5 w/ alum shaft might be good too.

well I would still advice forced induction, with a good tune, and conservative boost levels she would have no problem making 250whp on something that should last a very, very long time.

But if you would rather do it the hard way i sudjest getting some 1.8 roller rockers, they are supposed to be nice on our cars.

I just couldnt see redoing a rotating assembly on a brand new car.

But if you are hell bent on keeping it all motor then i would sudjest full exhaust, UDP's CAI maybe some mild head work, intake and definatly roller rockers.

But fair warning your going to be spending a lot more money, and not making as much power.

then again, that is the nature of FI vs. N/A

Ok, I hear you. I personally am I fan of forced induction myself. I have an 87 Daytona turbo and I wish I had a Kenne Bell on my Cobra, but she's also concerned about mileage. 20 year old college studen making $7 some an hour. I figure 190 stock at the flywheel with a 20% drop through the drivetrain, 200 at the wheels requires about 250 at the flywheel. I'm not sure if CIA with a K&N filter, throttle body, maybe intake manifold, and exhast with a good tune will exeed that. I'm sure it'll at least be close. Kill her budget though. On the bright side, she really wants to learn to drive a manual and get one in her car, so combine that with a alum shaft and I can figure aprox 15% drop instead. In the end though, a forged 4.3L rotating assembly for $1700 isn't a bad deal, and with longer stoke and proper choice of compression, as well as good breathing, it should still up HP slightly. but a proper stroke would really require full involvment. Intake, cams, maybe heads, underdrive pulleys, and exhaust in proper tune should be an easy 300HP with I would assume at least 350 TQ. More than my cobra makes, for less than I paid for it.

Man you have some big dreams of high N/A HP but i think if you made 300whp on a 4.3 all motor you would me makeing more N/A power then anyone else that i've heard of.

here is a dynograph of a 2001 auto with a CAI and cat back exhaust with an auto

you could go for a 5 speed swap.

But honestly i plead with you to just go FI your goal is going to cost a lot more then you think it will if you want it to be N/A. A procharger kit @ 8psi intercooled would run FOREVER. I've even seen guys run 11psi for quite some time and never have any problems at all. Most people upgrade the engine to run more boost rather then because the forced induction took a toll.

The key is a good tuner. Get a good safe tune and you will never have to worry about it.

I can't pull up SuperSix Motorsports site right now, but if you want to try its

www.supersixmotorsports.com

They took a V6 out of an 01, crankshaft out of an F150, bored to a 4.3 with forged rods and pistons, intake manifold, CIA, MAF, TB, cams, P/P heads and exhaust, I believe they said over 400 NA, then came the 125 shot of NO2. stuff it in a Fox with 4.10s in an 8.8 and their running 10s. Second stage 125 shot coming soon. expect 9s. They were like 8th out of 110 cars at FFW (Ford Fun Weekend), and the only V6. Gave me new appreciation.

www.3.8mustang.com also has a section for timeslips, a lot of 11-14 sec 6s. most are turbo, blower, or nitrous, and I know the stroker isn't two common, and probably (or really) not necessary for my girls application, but if your going all out, the extra torque of a longer stroke and nitrous never hurts. That TT setup will give you plenty of HP, a stroker with the right compression pistons might give you enough torque to necessitate some deep dish tires. And without having to worry about an independent rear suspension (Thanks SVT) 10.5" rims fit with no mods. Good deals on mustang tuning or ebay.

also try www.moranav6racing.com they have alot of stuff for your V6's.
I wouldn't get the aluminum driveshaft, not much gain from that, and you can put the money towards something better to add some HP.
My friend has a 04 V6, i helped install pypes x pipe, mufflers, UDPs, mac straight shot CAI, mild ported TB, 180 stat, superchips tuner, steeda shifter, royal purple in tranny and rear end, and he has Tlock and 3.73 gears installed. on his stock tires, he ran a 15.50 at 92 mph but spinning the wheels in 1st, 2nd and sometimes in 3rd. which equals around 200 to the wheels at his cars weight and his trap speed in the quarter mile track. But i know it can do better with drag radials. With a port and honed intake, ported heads and cam, it would probably run like a stock GT.

If your friend gets some drag radials for the strip make sure he knows he can fit 245s on the stock wheels instead of sticking with 225s. With how much $ he already droped in, why doesn't he just score some discount 17X9s and roll 245s around with 295 drag radials at the strip?
