i do not remember the details but you and are apakano are both right the issue is not the physical transmission bell housing but the mating of the flex plate, flywheel and engine and i think what HDDP did was similar to what Lantana is recommending.

 

lets say we get a better clutch not sure i want a stage 3 since that might be a little harsh but what will need to be beefed up to handle horsepower ranging from 350-500hp for transmission besides clutch and work on the gears or a transmission cooler.

 

yea stg3 is alittle overkill but he uses his car for hardcore autoX. i think TVT has the specs on what the diff stages can handle.

 

so honestly people can one start saving money up for a turbo setup i am tempted to call house of power and get into the details of this build up. It might be atleast a yr before i am able to do anything need to get some student loans knocked out before i splurge on power or might have to sell the system and downgrade the audio but upgrade power lol.


I am thinking i would like to start with a turbo setup on the stock motor and use that for couple years and then look into getting a fully built engine and really crank up the boost.

Now what do you think once the turbo is done get TVT 3.6l V6 with all the goodies does around 400hp before Forced Induction or should one go with a V8 drop in and use the turbo on it. What is compression ratio on the V8. i think our stock motor is like 10:1 and tvt plans to sell both high and low compression.


I think cost will be very similar in both but with the v6 being forged you could really crank up the boost and run 15lbs -18lbs on it and make that biatch scream lolz. The nice thing about the v6 is the savings in gas mileage versus the V8 but who is counting MPG i am trying to get down to 10 seconds. The v8 will yield even more power than the v6 but honestly how much do we need like i said i am happy to get to 10 sec flat in to long run and i think 650 hp should take care of that. I think the v6 on 18lbs of boost will take care of that but the V8 sure sounds nice.

i think the issue will not be power but laying down all that power nicely and safely items that worry me are

transmission (stage 2 clutch)
drive shaft ( one piece custom)
differential (phantom grip)
axles (????)

 

here is a good read on the different clutches and i think i would be leaning towards stage 2+ or maybe 3 if needed for extra power but i think 2+ should take care of it.


the clutch we would need would be from the slk320

this is what SPEC says about their clutches

Stages 1-3+ recommended for street/strip Stages 4-5 Race only.

Stock N/A compression is 10:1
I'm moving to Cali on Friday, first thing I planned on doing was running down to HOP and looking into how they could help me build a turbo X. Also About the one piece drive shaft, DSS (Drive Shaft Shop) said they would love to produce a one piece but need a donor shaft to build off of. In case you were wondering, a shaft cost $722 thru Ferris (cheapest way i know of). So unless you want to "shaft" out $722 or take your car out of commission for at least a mouth, we wont be seeing a one piece soon. I plan on sending my shaft out next time i get deployed, but that could be next year.

 

what a dilemma! i think the only reason id go for the 8 is for the souND! other than that the 6 cylinder build would probably be more cost effective.

 

thanks for the info on the compression not sure why i thought 12:1 that is high lol.

we could always get a drive shaft out of a wrecked car and members could all pitch in 10 bucks and once we sell the driveshaft on ebay or what ever after it is done we can donate that money to the board. I am down for 10 bucks.

let me know what HOP says maybe we can work out a group buy lol. i bet we could find atleast 5 people down for a turbo install.

 

I think a 6cyl would balance the car's weight better too.

 

the v6 would be very easy in terms of electronics and fitting since no parts will need to be replaced like exhaust manifold or other minor parts like radiator fan. The main issue would be the ECU and you could spend some good money to get it taken care of. i would rather put that money for ecu into the suspension or something and still end up with about the same power and less weight. Their is many pro's and con's V8 would mean you would never need a bigger motor lol or lets hope. we could use the v8 with a blower til it blows lol and then forge it and crank up that boost. Any v8 AMG that come forged for our applications.

 

I started a thread a while back asking people to search for shafts and such. Got one reply back from SquirrelCrusher, He said he would take his car down to the shop and let them build off his shaft. Only bad part was that he has a SRT, we found out that the SRT and N/A have different shafts. I told him to still go for it and get the SRT guys a new shaft but i don't think he did. I'm still totally down for something like that though. I learned from Nissan 240sx's that two piece shafts fall apart, can't handle power and actually cause you to lose power.

 

I am very strongly considering the TVT 300 kit and getting to 300 HP still NA. Then once there is more / better knowledge of the ECU and FI applications, add a turbo to that and really put some HP out. TVT is suppposed to put out the dyno figures today, I am anxiously waiting....

 

Yesterday I was in Utah on business and had some time to burn bewteen appointments and decided to stop in and visit Squires Turbo Sytems. I saw a twin turbo'ed Vette and saw some of their kits. I was very impressed with the quality of their kits and everything looked show quality. I met a couple of their engineers who also seemed very sharp and knowledgeable. They have sold two universal kits to Crossfires but they have also sold kits to some Mercedes owners. they mentioned that an AEM piggyback system would solve the computer issues and they are going to email me some contact information for some tuners that have installed their kits on Mercedes. The say they are making 25-35hp per pound of boost and that withi our 10:1 compression we should easily get 7 pounds of boost on pump premium and maybe even 8lbs of boost.

 

Good to know, even though I'm sure I wont expend the money, I've been following this thread. I do have a question for you though. If you put this on your current XF and then go through with the V8 as your signature implies, at a minimum won't you have to do another tuning mod if not a different system? So you may want to wait til you get the V8 done before you bother with the Squires.

 

I am interested in doing this After the V8 is running normally. I also think this is a great mod for the V6's.

 

Should have known that. Best of luck with you on this remaking project. Someday I hope I can see it in person when you are done.

 

Very solid work Lantana, maybe I will consider the squires after all

Please keep us posted on what you find out.

 

Maybe we could get a group discount!

 

depending on the price i might be done for one if we can get like 5 guys i think we could setup a decent group buy on the equipment and tuning i am in the midwest area and will travel to Eurocharged if we could get them to do a group buy on install and tuning.

 

I e-mailed STS to get some more information and some pricing info, no response yet. I'm willing to do this, have the fastest NA Crossfire out there.
