Default Turbo Chargers

Anyone know of any "turbo-charged" crossfires? I want the power of an SRT-6, but HATE automatics, which leaves me the option of modifying a regular Crossfire.

Just putting out the feelers for my options..

Oh my. If you do a search, you fill find TONS of info on this. Many have attempted or said they were attempting. There is even a twin turbo Xfire out there but it apparently doesn't run. Search and you will see.

Haven't heard of any turbo charged crossfires, but why would you want one when you can simply buy a supercharged one? A turbo charger added to the engine will be a major expense. You'd be better adding the supercharged motor to you limited crossfire with the manual. Besides turbo chargers work more efficiently with 4 cyliders anyways.
hope I helped.

I guess I opened the can of worms that most people don't know enough about and it ends in some sort of confusing debate as to what's better..
ok.. 1 - Twin turbo is HIGHLY effective and efficient on a V6
Mitsumishi 3000GT VR4 - 222 HP N/A 310 HP TT - 3.0L V6
300Z pretty much the same deal.. it's not a matter of how many cylinders but more of the displacement.
When you figure the displacement of a 2.0L 4 cylinder allows for more displacement to a turbo, 2.0L into one turbo, than a 3.0 V6 - 1.5L to a turbo the only drawback becomes the turbo lag, which isn't much of an issue with a set of smaller ceramic coated BB turbos. The only real concern would be the compression ratio and the crank. Everything else is tunable, or easily replaced (Fuel Injectors, Fuel line, fuel pump).
The fact is Turbo is much more capable of big power than a Supercharger is, but it does require a lot more work. I am in a unique position, because I plan to buy an engine in the next few months for whatever car I plan to buy... I won't be buying a car to go with that engine for at least another year. That gives me one year to get the heads done, the crank replaced, the valve springs replaced, and some lower compression forged racing pistons. I'm very capable of putting an engine together myself, so the real isssue is fabrication of parts (intercooling pipes and manifolds). That's what my questions was more geared for. Do the parts alread exist out there in order to turbo charger the car. I believe a twin turbo kit on a car like the crossfire is actually a bad idea, because of the dual intakes. I would be more inclined to attempt installing one larger turbo instead. I would have faster spoolup and a more efficient use of the turbo. So...
I'm guessing there's really nothing of the kind out there for turboing a Crossfire and what you get is what you got ... 215 HP is all you're really going to have, perhaps another 20-30 HP can be picked up with some aftermarket parts I'm assuming.
If anyone can link me to any forums or anything with a turbo charged crossfire that'd be great. I can probably get a good idea of what kind of work is involved and if I'd really want to take on a task like that.
My options on cars are a Crossfire coup, an Audi TT coupe, or a Toyota MR-2 Spyder...
The spyder isn't nearly as refined as the Audi or Chrsyler, I know, but has a lot of potential and is VERY fun to drive. The Crossfire is just such an awesome looking car, and pretty fun to drive from what I remember. Even with 215 HP it was pretty quick..
Well, thanks for the responses so far. and thanks for pointing me in the right direction..

I am attempting this.

I already have the turbocharger (internally wastegated), bov, air to water intercooler, and all the piping. I also have a piggyback for initial tuning but will correctly reflash the ecu (to get the afr's correct plus to retard timing) and take out the piggyback.

I will let you know when I am done.

Why reflash the ECU rather than a GReddy Emanage Elite or something? Just curious why you chose a reflash... I'd think the reflash would be costly, since a Turbo isn't standard practice for these cars.

Because of drivability, and the ability to precisley tune everything (like timing).

Also, I will be able to raise the rev limiter and take out the speed limiter as well.

Oh, and another thing, I may make a few kits for other people if there is interset so that way they can just send me their ecu and I will reflash it and send it back (well, a friend of mine in California will for that matter).

I can't wait to see how things are coming along for you. Any more details?

Well I don't want to give it away do i?!



Well one thing, all the piping (the charge piping and the exhaust piping) is going to be made out of 304 polished stainless steel; no crappy aluminum stuff.

Anyway, its going to take a while so expect it at either the end of this year or the begginning of next. (Have to test, get the tuning right (which is going to be a b***) etc).

And this is because? (Not being critical - just interested)

I can think of 2, 3, 4, 5, 6, 8, 10, 12, 16 and 20 cylinder turbo engines, I think even single cylinder turbo engines exist.


Are you refering to odd firing V6's like the old Buick? I know odd firing twins and turbos were supposed to be difficult.


The MB M112, although a 90 deg V6, has a split pin crank and is an even fire don't know anything negative about V6's and turbos except the split crank isn't as strong as say a V8 crank.

Yes you can pretty much turbo anything and everything.

Look at 600cc turbocharger kit for sportbikes, 1200cc oem-trubocharged Smart cars (sold in europe and mexico if anyone knows what I am talking about), or 16 cylinder 4-turbocharged bugatti engines...

I am amazed at how no one has gotten to turbocharge their crossfire yet... guys its just an engine not that difficult... ?

I think the main problem is it is the 90 deg V in a low engine bay at the front of a car with big front wheels so there isn't much space to the sides?

Perhaps HDDP will take his old NA engine and sort a turbo kit!!! Manifolds, pair of turbos (quad to follow), extend the IC in the V up into the area the SC occupies and go. Wonder what the crank, block and bearings will do.

no just time consuming ... when i was younger i built a few kits for cars i owned and loved doing it. but now i just don't have the time cause i spend it all at work trying to push my way up the ranks. and i suspect it is the same story for many on here that have the know how or at least the drive to do this ... no time.

ok im going to give my oppinion on this subject. i have limited dealings with turbos or superchargers but from what i understand the bottom end of the na motors is the weak link, so my though process goes towards using the bottom end out of a srt dont know if this is possible or not, iknow there are some differences between the 2 but i do believe the block will bolt up to the manual trans (hddp a lil help please). so my idea would be to get a complete srt long block or complete motor who cares, you can always sell off the other parts, bolt the na junk back up top and have a 20 psi bottom end ( i do believe thats wht ive seen some of the srts running) but at what point would it just make more sense to take that srt motor and run a stand alone??? i'm waiting to see what happens to hddp an latana tx i want the power but don't want to waste my money, and i want to retain my manual tranny, oh and anyone seen a stage 2 clutch cause that would be a major need in doing something of this sort?

I believe the bottom ends of the NA and AMG motor are the same, exept for the rotating assembly. I think both engines use forged connecting rods, but the AMG motor has completely different pistons, and a forged crank. yet I could be wrong, have you seen the AMG lower block? does it have a girdle or something? the NA block has 4 bolt mains from what I've seen in pictures on the site here.

just remmember doing the SRT6 or V8 swap will probably cost you $10,000. so you might as well pay Kleenman $10,000 and have them ship you their N/A supercharger upgrade. it makes 300hp and is the easiest conversion of all. If you get crazy later down the road you can take off the S/C and convert it to a twin turbo set up. keep the same pressure but the drag reduction might gain you another 40-50 hp

I personally would think it to be unwise to run any kind of alluminum block as high as 20psi. the machine work would be exspensive, your going to have to O-ring the heads. The smartest way of making power is to go with the v8 motors. keep it simple and normally aspirated for the street. you can always throw power adders on later.

Default Re: Turbo Chargers

some guy on one of the MBZ forum stated...

" RENNtech has added a supercharger onto a stock 320 engine and than bored to a total displacment of 3.8 L (~3,800cc). It's just the ML320 piston and sleeve kit from MBZ. This resulted in a total of 440 bhp, 420 lb/ft of torque...the key to this all is that they did this on a 6 speed manual tranny, but what surprised me was that the manual tranny could handle that much bhp. I was told there were no upgrades for it; however RENNtech upgraded to a Sachs twin-plate clutch and single-mass flywheel.." you could easilty add another 40 hp to that number if it was turbo charged.

these guys are on the east coast and can install it if your not handy with the wrench http://www.pes-tuning.com/

with the SLK38K upgrade you can hang with some powerful cars. http://www.conceptcarz.com/view/resu...ID=6014&hpLB=y
