I started a turbo diary thread a while back and then went back and forth looking at a s/c or turbo. One thing that kept me off the turbo was tuning which seemed to require an AEM piggy back and I have been following the rotrex build and while I am confident he will get it sorted out, I wanted something more simple. I leaned heavily toward the s/c when I found a very reputable tuner that could do all the tuning in the stock ECU. I asked him if the tuning could be adapted to a turbo and the answer was yes. I have also had many conversations with Rudy about switching to a 55K ECU which would solve my key start issue and get rid of the MAF sensor. Also the 55K ECU with the correct MAP sensor expects to see boost. There will be some issues to figure out becuase the 55K wants to see a bypass valve, intercooler pump and s/c clutch, all of which I will not have. Doing my research I believe each of these issues can be addressed. Jerry at Eurocharged also feels that this is a sound direction and has offered to do the tuning as well as Ken Rudy at Dyno Comp in Phoenix. Jerry being in Houston is much closer to me and he tuned Importlabs car so has some experience. If this all works as planned, any na Crossfire could be turbo'd to 9-10 lbs of boost and produce SRT power+ without breaking the bank.

 

Any NA Crossfire? So you're close to being able to find a way to turbo or supercharge even the stock 3.2L V6, well at least if this plan for boosting your V8 works anyway.

 

Yes, that is right. I have a na crossfire with just two extra cylinders, so if this works on my car it would work on any na Crossfire. The key for me and any 3.2 car is swawping in a 32 Kopressor ECU for a 3.2 and a 55 kompressor ECU for me. Rudy can adapt the ECU to your car. Both the na 3.2 and my 500 engine are 10:1 Selecting the right turbo is key. I am looking at a 67mm turbo with a T4 hot side with a .68 AR. With the right sized turbo, lag should not be an issue, plus from a dead stop you will still have your present power. A unboosted low compression SRT engine will be much more sluggish without boost and turbo lag would be more of an issue. If you know the parts to buy you can put together a higher quality kit for less than the cost of the STS set up. An advantage of the rear mount is it easier to do, and with jsut a small air to air intercooler can produce about ambient intake temps. Even if i have some lag, it won't be much of an issue since I already have so much low end torque with the V8.

 

Very Nice! So are you going to move forward with a turbo setup?

 

Now that is awesome. I may have to put my Zcar projects on the back burner for a while to try that out.

 

I had discussed going the Turbo route with Jake and Jerry some two years ago. They seemed to think they had a handle on it then. I would imagine, given their current file library and experience with our cars, this ought to to be a far less risky adventure now than back then.

Plenty of stock NA coupes about to be had for relative pennies. Wish I had the time.

Oh come on Franc, sometimes you just gotta make the time for something fun.

 

At 64 the sand is low in the glass.

Getting precious like that, one must make choices about use of time.

Yes, I am starting to buy parts now.

 

Hey Lantana...I've only been a member here for a few months. Recently had problems with my 04 Crossfire NA. It would turn off while driving. As the codes didn't help, and neither did a Benz only mechanic, I found other posts here that pinpointed the issue to the cranskshaft positioning sensor.

Anyhow, that's how I started lurking and found some of your threads 2 days ago, both the one where you started the V8 swap and now the turbo upgrade. Pretty f'n awesome!...considering, I myself am just trying to get all the lights on my dash to not turn on while driving, LOL.

I bit off topic...I have a project 67 SS/RS Camaro I am working on...gonna upgrade it to a '90 ZR1 LT5 with a T56, as well as convert it to a full corvette suspension (front and rear), and with an IRS on the back. All parts are in hand. I also would love to twin turbo my LT5! But, as you well know, first thing is first, get the engine running first.

I only mention this to show I can appreciate what you went thru in your conversion. The electronics are my stumbling block as well! Hence, my inability to correct the light show happening on my Crossfire dash! LOL

If I didnt have my other project with my 67, I would love to follow your lead and convert my NA to a V8...might not be able to resist after reading all of your posts!!!!

Well keep up the good work with posting on your turbo research! Definitely awesome to read! Too bad you're still not in SoCal, would love to see your Crossfire SRT8 up close!!!

 

robert whatever you do don't tell tec-9!!!

 

Now was that nice?......lol.....

 

Whatever happened to that project...

 

Hey I am still here and this will be completed in the next couple of months. I have been getting my parts list together and made a few calls today looking for a decent price on a 55K ECU. I have been studying this like crazy. I have had some recomendations on a turbo, but I have been busy learning all I can. It looks like a 67mm turbo is my best choice.

 

My comment was in no reference to your projects Lantana. I actually have the greatest respect for what you have done and are doing. I was referring to the Tec-9 I'm going to make my similar too or stronger than a 6. Apologies and no disrespect meant.

Jason

 

No appologies needed at all. Sometimes a alot of time goes by without any updates from me on my projects so I thought I should give an update. When a lot of time goes by without updates I am usually just very busy with work, trying to research, learn, plan things out. figuring out how to overcome potential problems and making contact with those who will need to be involved with things I can't do myself.

 

Subscribing.

Robert - you have done a lot for the forum and continue to share your knowledge with us on a daily basis - Thank you

 

There's an new Godzilla movie announced, the new Mortal Kombat just came out, I'm finishing my degree, I lost 70 pounds, Osama Bin Laden just got killed, and there's now a chance to turbo my N/A. How in the **** could my life be any better right now? This is too good, now watch me end up dying in my sleep tonight.........

 

Hopefully you don't finish up that turbo project right about the time old Obama has gas up to $8 a gallon

 

Don't turbo's improve mpg? Besides, at least Obama caught Osama....lol. I drive my XF like 4 times a year, I can deal with 8 a gallon, its the potential emissions laws that scare me as there is no place for catalytic converters on any car of mine. I'm opposed to their existence.
