stroker

[1eliminator1]

just interested in what people think about stroking a 4.0?

[neohic]

Helps make it fall asleep faster. :roll:

 

 

 

... but seriously, I like mine but if I were to do it again I think I'd just stick with a 4.0 and an HO swap.

just interested in what people think about stroking a 4.0?

 

I am currently figuring out what all parts to put make a 4.7L stroker with a 1997 motor for my Comanche. Of course there is a lot more to this than what I listed below. The nice part is I live less than two hours away from Hesco who specialize in machining 4.0L engines for strokers. :D

 

I have:

1997 NVH block, 1997 head

1999+ horseshoe intake

4.0L connecting rods

 

Sourced or on the way:

258 crank, 3727 casting

KB IC944 pistons, 0.060 over bore

 

 

Lets not get into the part where I am considering putting a turbo on this...

:hmm: i am not to sure about that :dunno: its all about how well you maintained the motor and how well its been built.

I'm building one. Drove my first one in about 1990 or so.

 

Pretty wild one though. It was a project MJ built by Jeep Racing. Hesco 4.6 with a Paxton supercharger and Electramotive programmable fuel injection. Shortbed 2WD, lowered with wide tires and IMSA type flared fenders. Screaming yellow in color.

 

I believe it went to the crusher after a few months.

:huh???: motor and all :(

I like mine, better gas mileage and more power than my stock 4.0. It cost more than I had budgeted for it, but a motor isn't something I wanted to do on the cheap.

[1eliminator1]

So since i don't have much of a budget right now, it doesn't seem like a good idea. Maybe someday

I think it was JP magazine that just did an article on 4.0l strokers on two different rigs with dyno numbers.

 

From what I read I would have to say its not worth it. The money would be better spent elsewhere.

[Rymanrph]

With 200k miles on my motor, I know that a replacement is in its future at some point. I'm of the mind that if I replace something, I want it to be better. If a stroker isn't worth it, then those looking for more power, what would be?

if you are referring to this article i didn't find anything slamming the stroker. :huh???:

I support the stroker the build. :cheers:

A stroker IS worth it. Anyone who tells you it's not has never had one or is misinformed. Just my experience:

Let me rephrase my original post... Not that having a stroker isn't worth it, but for the cash I have invested in building mine there's just some other things that I would've rather have spent it on. Now that it's in there, it's a ton of fun!... just not totally worth it to me.

I've been aware of the possibility of stroking the 4.0L using the 258 crank for a long, long time - well before anyone was offering commercially-built versions. It's intriguing, but IMHO it is not something the average do-it-yourselfer should even consider attempting. The problem is that the deck heights between the 4.0L and the 258 blocks are slightly different, which means that there's no easy way to get the correct compression and avoid detonation. The best solution seems to be to use 4.0L rods (which are stronger than 258 rods) with custom pistons. But they have to be custom pistons, because the vertical location of the wrist pins is non-standard.

 

Not being wealthy, after years of considering the options, I've decided that if I ever have to rebuild the engine in one of my XJs or MJs, I'll keep it a 4.0L and go with an aftermarket cam grind.

 

Whether or not a stroker makes sense for you depends a lot on how you drive and will use the vehicle. The longer stroke means the engine can make a lot more low-end torque. It'll make more horsepower at the top, too, but that's not where the advantage lies. If you want low-end "grunt" power (torque, in other words), take a good look at a stroker. If you drive mostly on the street and your style of driving is to spend a lot of time in the upper part of the RPM band, IMHO you'll get more bang for the buck by building a stock 4.0L and choosing a more aggressive cam grind for higher RPM.

Wow, this thread is depressing. I am building a turbocharged 4.6 stroker right now, probably going to spend $3500 by the time its all said and done. Hope all the time and money will be worth it.

the article i read they did two different Jeeps with before and after dyno numbers both Jeeps only gained about 25hp and around 50 ft lbs of torque when they were done, IMO not worth the price of a stroker build.

 

it might make sense if you have a ton of money or you have already done everything and your looking for something else to do to your jeep,other then that just take the money you would spend on the stroker and put it into other parts of your jeep.

Hopefully you are spending your quality time over on the stroker forum and not looking for educated answers and/or stroker opinions here. You won't find them. I'm not bad-mouthing anyone here, but very few CC members have any experience building a stroker engine, including me. I just put in a basic stroker crate engine then built it up with the peripherals. So take what you hear here with a grain of salt. Don't get depressed. :cheers:

While I don't have first-hand experience building a stroker, I do have second-hand experience -- working on a friend's stroker, and then helping troubleshoot the problems after it was in the vehicle. And I used to spend a lot of time on the strokers forum, plus corresponding with guys like Dino.

 

All of which is why, even though I have built two street engines (V8s) and one race engine (V8), I would not undertake to build my own stroker engine. If I were to win the lottery I might spend the money to buy one from Hesco, but I just don't think it's something that the vast majority of us here are really prepared to execute (properly). And I also don't think it's worth the money involved.

Exactly what I was saying. No one here has any experience building strokers. Yep - Dino's a good guy, but all his expertise is based on a single engine build.

 

And I also don't think it's worth the money involved.

Your opinion. I disagree. Run a good running stroker for awhile - you might change your mind.

 

And yes, Hesco engine prices have gone through the roof now, based on their excellent rep and because it's the best product out there. They still sell well even in this rotten economy. I was able to buy one several years ago when they were competitively priced. Would I buy one now? Nope - too expensive. :thumbsup:

I don't agree that they aren't worth the money. I spent more than I would have liked to, but you have to pay the money to do something right so it lasts. $3500 for a turbo stroker is a very reasonable price, my NA stroker cost about the same and I did all the work myself.

$3,500 for a turbo stroker is CHEAP!

:agree: i spent many of days & nights months on this forum and i too would recommend this site anyone considering doing one of these projects :thumbsup: . Get your pen & paper ready take bunches of notes and do the research. when i was looking to do this i'd the research and i have narrowed my choices down to three Clifford, Hesco and Accurate Power (kits). i choose AP (kits) and shortly after the installed of my stroker the site was down for a while :dunno: why. i am pleased :banana: with my experience of assembling my own stroker. it was a great learning experience and had no issues up until the suburban decided attempt to park in the bed of my truck. btw i still don't know what caused AP to shut down for a while :hmm: and i guess i'll never know.

That's what I was thinking but didn't want to say it. It must be all used parts with no machine work to the motor.

I have $300 into my stroker parts so far. 258 crankshaft, connecting rods, block, head, intake manifold. Once I am done with all the other parts and machining work I will be around $1,500 with a top budget of $2,000 for just the motor.(Does not include air intake filter/tube setup, exhaust, and other little things that help the power otherwise.) This is for a 4.7L stroker running around a 9.5:1 compression ratio. I am patient at finding the right deals.

 

I looked up all the prices to go to a turbo for the best price and it easily added $3,000 on to the cost for mostly new parts. The turbo, exhaust manifold, and electronics being the biggest costs. It is possible to create your own manifold if you have the patience to do it correctly for the best flow. If you have the software and experience tuning it will significantly drop the costs of tuning the setup by avoiding dyno tuning fees.
