Re: 3.7l performance love

Just remember....shiny ports arent everything...

Last I heard for aluminum heads he charges 500 per set IIRC, 50 to flowbench, 200 to assemble.

Re: 3.7l performance love

Ryan, you gonna do something like this when you move in



Buddy did just this in his shop and its nice tool he uses on his M cars. Does his own porting and has seen some very accurate readings with this setup compared to a professional bench setup.


Airmrams stuff is overpriced and doesn't seem like there are any actual #s or PROOF behind them, not that they dont actually produce any gains. And Killians work looks very nice but seems like hes only into the super street and track stuff. Would he do a 3.7 Jeep head? I think those guys offer a nice little option for the 3.7 but if guys are going to be getting into then I personally think they may as well match up a nice little cam and have it dynotuned and a wideband installed. Thats almost required in reality but at that point Im thinking are the gains worth it for the $ on a 3.7 Jeep? Id want to do it but cant justify it at all especially as Id like to be into a new SRT in the next two years :/

Id be curious to see a track time for a 3.7 with ported heads and bigger cam and a tune to match. doubt that exists though, demand and following just isnt there, but why would it, anyone performance oriented wasn't buying a 3.7L Jeep, were they?

He has ported heads for a 2.4L Altima/240... But a lot of those guys love 240 for the rear wheel drive rice..

hmmmm well maybe he would do somthin for us if we got few guys together?? Almost pointless though unless he could do a set of heads for like $500 or less, thats most I could justify on these slugs.

But like you said the rice demand is high, always has been since Tokyo Drift came out . Thats the funny thing about business, doesnt matter how serious or legit something is, if there is a market there will always be a supplier and an industry will evolve

Actually yes, that is the plan I think. Only problem is I would like to do throttle body testing as well...I dont think im going to have the ability to do that, unless maybe I make a manifold that sucks from 3 or 4 vacuums at one time

Air Rams heads are done by Knowltons. They are supposedly pretty good. Killian has done several sets of 4.7 heads and they are very very good for the money.

If I had a 3.7 anything and was bent on going reasonably fast with it, I'd throw on a turbo and tune it with either SCT or an FMU....

You guys are absolutely crazy. 500 dollars for 2 heads to be fully ported is a STEAL. Thats 250 a head! I could do it for that much but the work would not be as thorough for that kind of money. Then again he probably has the experience to be able to make it through these in relatively short order.

Re: 3.7l performance love

Oh yeah FR, no doubt they are a steal. but then labor (cuz IDK WTH im doing within th engine LOL) and other parts etc. A bit too expensive compared to the actual gains you would get with the 3.7L.. I assume

Re: 3.7l performance love

It all depends on the combination, but, again, if I was stuck with the 3.7 I would go with some sort of boost...These engines work very well for that, aside from the pistons/rods . Keep the boost reasonable and they will last.

JeepKid is sending me his '08 manifold hopefully tomorrow. I knew it would be a PITA having swapped manifolds in a 4.7 WJ, but evidently Chrysler never designed the 08+ 3.7 to be able to remove the manifold with the engine still in the bay. Unless there was or is some sort of glaring oversight preventing the manifold from being removed, it appears that a small, invisible (once the hood is closed), cut is going to have to be made to remove the manifold. Oy.

Hopefully I can work my magic on it. I do not THINK this will be an issue for 05 and 06 3.7 WKs.

Re: 3.7l performance love

^ Yeah I always wanted to but I know the piston/rods wont handle cause people were saying the top ring land couldn't handle it I believe? Either way wouldn't be too hard to get some forged low comp pistons/rods and bolt up a small blower of some sort but even then, is it worth it, what other costs will come in?


Id be able to do all labor in house to save $ but still, would need to get on a dyno and yes would love to have SCT hemituner tune it up but I believe he is down in NC. Im sure we could make it work haha I think he does like $350 complete customs tuning so $350 for that.

Parts/Cost Breakdown:

But say for pistons/rods you're looking at maybe $750-$1000 for a nice rotating setup (ballpark)

Then blower kit (do they even make one anymore for the 3.7 jeep??) would have to get individually pieced together and probably cost on average - $7500 give or take $1k maybe?

Also need a nice wideband setup of course and at this point may as well grab a cam setup for the blower and the get heads done to match that. - $2500-$3000 call it -(heads/cam/valves/springs/wideband)

Add in full exhaust which will be required at this point ($1000) pieced together and welded up at any reputable shop

Add it all up you are looking at $12,000+ easy to get the 3.7 to effectively run some boost and make some real power.

I suppose you could skip the heads/cam and just run blower on the built bottom end but still would be skeptical of valve-train and then gains wouldn't be near what they could be. Id bet the 3.7 could be well into the 400+whp range with the big setup on like 8+lbs of boost but for $12k, is it worth the hassle and risks down the road?

The person you speak of is Hemifever. Hemituner I believe is in NY and is a completely different person.

There never was a SC kit for a 3.7...But a 4.7 kit could probably work.

Best bet would be a remote turbo, it could be done in a weekend, the low IATs would be ringland friendly.

You've been reading too many car magazines. You dont need big $$$ heads and cams to make decent numbers. Are they nice to have? Sure. Are they necessary? No. Buy some valve springs that will work, about 200 bucks, swap into existing heads, and call it good.

For about a 1/3 of that, you could probably run 250rwhp (8psi), have more hp/tq than a modded 4.7 and some 5.7s, keep it safe on stock internals, and not break the bank.

I dont know how the WKs are, but 545RFE'd 4.7 WJs with the 247 case were seeing about 28% parasitic loss, more with big tires. Youre not going to see 400whp out of ANY 3.7 on 8 psi.

Re: 3.7l performance love

I got quoted, out the door, at a place called gear heads here in TX. They quoted 6 grand out the door for a turbo kit with dyno to get tuned right on stock comp. I'm sure with my SCT it would be much better

How did they plan on tuning the stock comp? Lol...

IIRC you can flash the 3.7 NGC PCM with a 2 bar MAP program but I dont think or know if it would work any better than SCT. Then again SCT 2 bar MAP tuning is not great to begin with, it is a hack. PCM flashing is really a thing of the past anyways.

If you run the boost low enough you could simply trick the MAP sensor while running a 1 bar MAP into not seeing boost and a safe AFR...but that would give you very little flexibility as far as tuning/adjusting boost is concerned

You can run a FMU and bigger injectors, but again, not a great way to do it.

If I end up getting a Dakota I will likely run an FMU, and use SCT with a 1 bar MAP to eliminate IAT timing retard and to lower the open loop threshold.

That shop probably planned on running a piggyback...Be careful as these transmissions AFAIK depend on MAP voltage- the very thing the piggybacks manipulate- for proper operation. Start pulling fuel and manipulating MAP signal....bye bye transmission.

You really have to know what youre getting into when it comes to this sort of thing. I am still learning.
