you need to make some custom ones and remount the A/C dryer, but it will fit with some time and effort, which is the route I am going for, I just do not think the car needs an bottom end torque, that being said feel free to gear up your S/C so there is some lag to move the power around on the band.

The reason I am thinking supercharger is because it will just be easier overall. I am up for the challenge of a turbo build, would much rather a turbo than a supercharger, and feel capable EXCEPT for when it comes to the A/C system and making new lines. That just sounds like a real PITA to me and I hate not having A/C.

Is the A/C dryer not tucked under the passenger headlight? I am not at home right now to go look but from what I can find online, it looks like it would be out of the way of the turbo.

Why donīt you use a small turbo and do a bottom mount instead of the top mount? I donīt think one needs a GT35+ charger to make M54 fast.

I have been talking to Hobbit and for my goals I will definitely be going with a smaller turbo.

I have thought about bottom mount but I just really love the idea of having a top mount and the CX racing kit makes it simpler. I don't expect everything to fit properly right out of the box but it gives me a great starting point. If I was doing complete custom fabrication I would have gone with bottom mount because I feel like it would be easier. Does the aluminum underbody shield need to be removed for a bottom mount? All bottom mounts I've seen have had them removed which concerns me (although I could get on the alignment rack easier without it ).

Also, Daniel....I just looked over your MS43 wiki and I wanted to say thank you again! It is absolutely incredible and I am excited about where things are going based on your headings!

When sizing a turbo, you really want to be talking with someone who has access to compressor maps. It makes a huge different in performance, lag, efficiency, etc. Just making general assumptions is a hit and miss proposition.

I am glad someone came along with this input, to many times people just wait to see what turbo everyone is is strapping on and it is true every setup is a little different but those maps really tell the story. I am sticking with the Gt35 to try to move the boost higher up in the RPM band until I can see how the AWD system handles the boost / added torque, I am skeptical a bit. but I also like unique cars so here we are.

my A/C dryer is behind the headlight (same difference) I figure you have 4 options, drop the whole system, make custom lines, get an electric setup, or go supercharger :p if you make custom lines you can move it where I did or down further into the bumper. either should work. I just thought my spot was cleaner when i tabbed it. as far as I have read any top mount turbo kit can be turned into a bottom mount turbo kit by simple flipping it and rewelding the flange, btw. also I left all the OEM heat shielding in place

finally an update. sorry again.

took a break from welding to plastic-dip the car.



pretty amazing how far away it can look like matt grey / black but up close you can really see the flake in the plastic-dip



overall super happy!


technically the front bumper is not painted cause my spray booth was to small but the over spray blended nicely thumbs up for Antherciate grey from Plastidip

I also installed the PMAS MAF sensor as well.




decided to move my oil return to the front of the motor since i have to replace a few bearing in the belt system on the front, so soon I will be pulling the front of the motor off to replace all that

I really appreciate this input. I know a lot goes into choosing a proper turbo. I have done a ton of reading and some plannig based on others builds but still have a lot to figure out before I jump into it which is why I'm asking questions.

Deciding on a turbo is one thing I had no idea how to do. I've had different Turbo's recommended to me but I don't think any of those people were basing it on any real data

Any recommendations on who to talk to? Do you have compressor maps?


Also, Joe, did you just get the regular PMAS HPX Maf? Or did you get one od the other models?

I do not have access to maps. I have friends who do (one of whom is an engineer for Garrett).

Here is a good place to get started learning about sizing turbos:

http://www.motoiq.com/MagazineArticl...p-Details.aspx

Do a search within MotoIQ and you'll find more info about sizing, including a quick and dirty chart if you have nothing else to go by. Best bet however is to find someone who does have access to turbo maps to discuss it with. Then you have to decide whether or not they know what they are doing with that data.

I agree, build threads can be fun to read.
Mines nothing super special but I enjoy sharing what I've accomplished and learned,
plus sometimes they help others know what is possible.
