I think any Intrepid with a 3.5HO with the 2.7L final drive gearing in the transmission, with a good intake and exhaust system will surprise the hell out of a lot of people. Know this, no naturally or turbo aspirated ricer has beaten me - destroyed a Skyline R32 few weeks ago from one light to the other on a dead night. :P

There is another alternative if someone didn't want to go into the fabrication for twin turbo or couldn't track down a Prowler turbo kit... The turbo/supercharger kits available for the LX platform (Magnum, Charger etc.). After all, with the exception of a new intake manifold and accessory arrangement they are the same 3.5 motors. The kit costs $2000-$5000, lots of them around.

You would have to rig up your own belt system, and it's placement, but it's more easily do-able than anything. You may even have to do a bubble on the hood to compensate for the turbo, think like the bubble on the old eagle talons or mitsu eclipses (Simple work really).

Here are a few pictures in Chargers and Magnums. Generally, I've seen Superchargers, and centrifuge turbo's used.

As I said, it can be done, it would just be expensive. 100% of everyone that asks this question has $20 bucks in there pocket and no intention on actually plunking down a few grand to make this happen, nor do they have the skills to do the fab work. Anyone who has the slightest skill or real inclination to do it would start with a project log, not some vague question. No offense to the OP, but any of us who've been on the forum have seen the question asked a million times, and no one that does ever has any skills to actually do it. Maybe we're just dis-illusioned.

Someone should do it, just to see. All I ever see is idle talk or some kid who thinks it can be done for $200 bucks with a bolt on kit like his Honda friends. But if I were going to drop five grand on an Intrepid build up it would NOT be on a turbo, it would be on a rear wheel drive/Hemi conversion. That's where the action is. Then Supercharge THAT. Make it like Ma Mopar would have.

Someone was puttering with one of those intakes recently, the hood doesn;t close on them. Damn cab forward cars Would have to put a bulge across the whole hood. But yeah, if someone were to try it, probably the best plan. 5K easy investment after dealing with the computer and all the other shenanigans you'd have to get done.

There has been at least one turbo or supercharged M IIRC....but I can't find the info. I'm sure Tom R will remember

this is what we usually see when it comes to Imma do a turbo thread http://300mclub.org/forums/viewtopic...20&hilit=turbo it's a good laugh

beeblebrox82... Will you marry me? Now you're talking, a buddy of mine has a 426 Hemi literally SITTING in the corner of the garage. Spent many nights looking at it, dreaming, engineering how I would put it to use in my Intrepid Project. :P

Mopar or no car.

But no, I totally agree. I remember back when, I Google'd turbo Intrepid to see if someone did it, or if kits exist etc (amusingly how I encountered a lot of these LH forums). Lots of threads with comments like "forget it", "more than it's worth" etc. At the same time, no one is ever serious enough to do anything, thinks it's like bolting on a eBay coldair intake - you and I both know it's anything far from that. Especially when you start running up against issues where your PCM/ECU is rendered useless and your using aftermarket systems.

There have been threads about some heavy duty clutches or something that are made for our trannies.

I floor my high mileage 3.5 HO with 2.7L gearing all the time, roasts the tires. Tranny works fine with the exception of my mounts being wore out.




You can buy kevlar clutches, etc. If you check out the general section under second generation, there is a large debate over whether to rebuild OEM or better than OEM etc.

I love my car and all, but please don't act like even a 3.5 with the gears is really that fast.

Also to those saying that nobody has really tested the transmissions with this, they are wrong.

Turbo was a guy here back in the early days of the site, and poked his head around lurking for a while. He got into the 13s with a turbo setup on a 3.2, and eventually blew up his tranny. Prowler guys that push tons of power would have spare transmissions to drop in because they regularly would blow them up;. I'm not saying you can't do a lot with the 42LE, but it is a big limitation.

Nate is right, if you have to go a stand alone computer route combined with a mediocre tranny there isn't really any reason to keep the stock drivetrain for a massive power build. That has been done a few times before. One guy had an LS1 drivetrain in a LHS, and I've seen a V8 Intrepid on other sites before that was legit (but it takes tons of custom fabrication and welding).



My car won't ever be done because I'm insane. That is all.

Sigh I never implied I was "fast", you don't need to be fast, have a turbo, or a Hemi to spin tires. Torque is all that's needed, and with a 3.5 with the difference in gearing, she'll more then easily spin the tires. Put on some hard rubber kicks and give it a good jab and she'll clean them to the cords - hell yank the e-break if you want to go to go to town standing still. Considering friends with brand new 2010 $80k GM's with V8's can barely get the tires to chirp, I think us LH boy's are doing pretty damn good!

Frankly, I don't understand your ground for debate. I'm simply contesting the previous comment, just because one SE sh!t's the bed when it's floored doesn't hold up much against all of them, given the excessive "abuse" mine is always put under. Given he did imply that all of them would do the same as his friends. If the difference in experience teaches nothing, it's a crap shoot!

Who is not to say with the right circumstances can you make the (or any) tranny handle the needs - that's been my grounds the entire time I've posted on this thread. I realize these tranny's weren't designed to be bolted up to a 440 Hemi and launched off the standing up on it's rear wheels; but the amount of flack they get is ridiculous, problematic or not.

In any event, if I was going to do a huge build up, like you've mentioned many ways too do it. Personally, I'd stroker a 3.5 to a 4.0, set it up just right and twin turbo it to handle 12-15 PSI, which is a nice light but good range. Snag that LX read-end and RWD tranny out of the vandalized Charger at the yard for peanuts and have myself some fun!

That said, I know a few prowler guys that push 12PSI on their prowlers, no issues. But they have a spare 42LE waiting, given the amount of 2.7 failures, parts are easy to come by. It's a matter of how you drive it after the fact I suppose. Even a $500,000 dragster will fly all to hell just warming up the tires, or going down the 1/4 once.... Seen it many times! :P

So with everything said, who's gonna drop one of these in a LH or LX first?

I wonder about the quality of your tires. If you've got tires with poor traction, perhaps they are "saving" the transmission by "breaking" first?

And to toss in an idea prompted earlier in the thread, the load on a transmission isn't the only factor to consider. Impact loads (such as jumping into forward from neutral/reverse, for example) are very hard on transmissions. Service factors for transmissions designed for impact loads are on the order of 2.

(Power transmission was a subset of a former job.)

Oh I didn't mean to doubt that you can spin your tires. I can easily break mine loose with what I've done with my 3.2 if I want. My references to your claims about the car's speed are mostly about this.

"Know this, no naturally or turbo aspirated ricer has beaten me - destroyed a Skyline R32 few weeks ago from one light to the other on a dead night."

That statement is full of itself. A 300M special is a 3.5HO with the 3.89 gears, which rolls off the line with a 7.4 second 0-60 time.
source (which has been confimed over the years to be quite reliable): http://www.albeedigital.com/supercou...0-60times.html

That same site didn't have the R32, but anywhere I looked referenced ~5.6 seconds for the 0-60 time. I'm not saying that your story didn't happen, but it's only true if his car was in very bad shape or he wasn't trying. The facts just aren't on the side of the story.

Also my debate on the transmission is contesting your specific point of "no one *has* turbo'd one so who's to say it will sh!t the bed or work just fine?" Yes, someone has done it and yes it did shit the bed. I've been around here since those days and remember watching build threads and videos of his car. It was pretty sweet, but just didn't hold up that long and the guy dropped out because the tranny was too much of a roadblock for him. That doesn't mean it can't be done, but your statement of no one has tried is inaccurate.

I am all for attempting a beefy version of our transmission and out there projects. I have a spare 42LE in my garage and a bare 3.5 block that I'm going to stroke some day, along with a spare set of heads that I'll have done up to go along with it. I also fully plan on getting into welding and building my own headers as a learning experience (I already do non welding metal work for my job). I don't mean to go against the spirit of your posts, that it all could be done, but the individual statements didn't line up.

Also as someone that's been around a long time I've seen this song and dance before. All the old timers tend to get pretty jaded. At least once every few months these kinds of dream threads pop up and it's never really a matter of what's possible, it's "are you ballsy enough to go for it" and actually have the capability to pull off such a custom project.



My car won't ever be done because I'm insane. That is all.

By the way, this is the guy that did it for real.
http://www.dodgeintrepid.net/members/720-turbo.html

Unfortunately he kept a ton of his stuff on his own website that is no longer hosted. I do still have a dyno and burnout video of his car saved on a hard drive somewhere. I'll find it and upload it just for fun.

Alright, I dug them up and put them on my photobucket. Not the highest quality videos, but definitely the real deal.
