I have access to dyno tuning, and an MR2 guru (who has tuned many turbo MR2s to date. Ones from basic street custom tunes, to full builds, as he builds engines for customers all the time). If you're willing to help me piece together the hardware for my Z4M, I'd be quite interested in attacking the tuning portion come summer when I have more time on my hands

We using gotech management system.



As far as $5000 for a kit. Wow that's cheap. I paid with the exchange rate $20000 that excludes brakes and kw suspension.
Sounds to me like one of two things.. issue with drive by wire.. or possibly a cam issue.. cams are locking, or not locking and getting confused. Are you controlling the cams with your ECU? If not what is your strategy to keep them from wandering?

Discount sure.. but definitely not $1200 discount.. what Jason would most likely do is provide a basetune for free to AFI and sell the ECU's to AFI for a discounted amount so long as they're sold as a 'kit' with hardware.. but even so we're talking ATLEAST $3k+ .. there is NO WAY you're picking up the ProEFI 128 and harness w/sensors and boost controller/etc for less than $3k..

Sort pointing a light where there was no darkness really.

Anyway.....hopefully something can come from the outcry for this kit. I've moved on anyway since my Z isn't an M and really doesn't apply to this build request.

I did go ahead and buy some catless AR Designs Stainless downpipes and a set of low mile OEM N54 turbos and manifolds.

If I get time to work with someone like AEM, MegaSquirt or whoever wants to try an S.I. N52 F.I. project...I can do the rest of the fab.
Trust me.. it may look like Lutz is trying to drum up business with pretty pictures/etc.. but they're not.. they're genuine car enthusiasts and Shawn is simply trying to help someone avoid getting into a turbo kit that they can't afford.. and what I mean by that is.. if you're stretching to put together a $5k turbo kit you'd better..

a.) Know what you're doing and be doing it yourself
b.) Be being a tried and true solution
or
c.) Have an extra $15k in the bank 'in case' .. because I can guarantee you you're going to be dipping into that.

Not trying to discourage ANYONE from attempting to build a budget solution.. but I am trying to discourage anyone from having someone else try to do it with their car.. with BMW's and VANOS .. and Drive By Wire, and Piggy Backing/Etc.. its not that simple.

I'm neutral in regards to their posts. I mean...they are giving the rest of us things to think about; which is always good. I'll definitely tread waters carefully no matter what

Obviously A4RIngedONE8T is as determined to discourage this low-buck project as he can.

Which is odd in that most of us on this forum have been complimentary on your build thread.

This is one of those builds where joy could be had if a $700.00 DIY'er ECU such as MegaSquirt would fit the bill. Oh wait.....they do ! That includes harness and sensors in most cases.
I have already mentioned somewhere in this thread the base cost for the ProEFI for the Z4M, and then it's posted that it's going to be had for $1,200. Clearly what I said went right over everyone's head and they assumed otherwise. I'm just telling the facts, again, sorry

That E30 is a perfect example of what's going to happen if someone jumps into this for "5 grand." The E30 build was started by another shop, after 3 years, and still no running car, the plug was pulled and it was brought to us to attempt to save the car, and the customers soul. In a very short time the car was running and we began to find all the opps's from the last shop trying to do things on a budget. Some projects just can't be done on a budget and the Z4M is most definitely one of them. Hell, we get other people's screws ups in here all the time, remedy them, and send the customer back on their way happier than they could have imagined. There's a reason why we are so stubborn with our opinions, it's because they are true! I'm not telling you to bring us your car because I wouldn't touch it for an insufficient amount of money, I'm just telling you to use your brain and all the resources in the industry before you jump into a build you can't handle. No one deserves a Z4M as a paperweight

Seroiusly......

I'll remove the pictures if its that big of a deal.... Exactly what Shawn said was my point.

This is a F/I discussion forum, I didnt list pricing or even what was done to the car.... So I fail to see how that's "cockblocking"... Not to mention we have never listed pricing for a Z4M setup... And their is no official word on pricing on this setup either... so its not exactly a "hey buy this" thread and me trying to direct traffic another way..

But obviously your agenda is to nit pick....

I was trying to explain to you guys where Shawn is coming from, and hes not posting to be a dick or "discourage" people from doing their own thing. hell he started welding from scratch because he wanted to, 100% self taught, so if anything he would love to see any of you try your hands at your own builds... Only thing is there is TONS of misinformation in this thread, and he was trying to give HONEST feedback from his years of personal experience (has a top mount Z3M turbo setup he built himself) and you have either attacked what he had to say or attack me for posting pictures....

again I'll re-state what I said in my last post...

If Anyone Has Questions EVEN IF ITS NOT A BUILD FOR US TO DO.. Please feel free to email myself or Shawn at ANYTIME, and we would gladly give you feedback and our honest opinion.

Good luck and start boosting guys!

We are here to HELP the community not discourage you guys from anything.

The pictures are COMPLETELY non related to this thread....

No pricing was advertised... Not even what was done to the car...

Purpose was to show you guys 2 things
1. The work Shawn does is not isolated to the Z4M platform
2. That he IS knowledgeable on the subject of BMW F/I and the Z4 isnt the only car we have dug into.

Im not against andrew posting in here. If he has something he can contribute to figuring out a cheaper way to do an FI build on the Z4M then great. As for Pro EFI first of all it is on sale right now for 2800. And then there will be a discount on top of that.

definatly look into re-inforceing the stock intake manifold.... it will take boost and save you a fortune, these fancy cast intakes are great but are a big chunk of the costs of FI and at low boost levels arnt really needed imo!!

Agreed!

I'm not sure how much boost the stock manifold will take abuse on though. I've seen other blow them with relatively low boost (under 10PSI).

Mike at Maxpsi is working on a ECU tuned kit for the E46 M3, using the stock S54 manifold, and he will definitely let the community know what the limits of that design is!

Again guys, good luck and happy boosting!

I'd like to get my hands on a manifold that is free...something perhaps damaged in a wreck so I could cut in half and study abit.

Once the interior wall tolerances are understood better....a CF version could be entertained.

Although... I'd bet a 3 cross sectional spiral wrapping of one ,in good shape might test out to some pretty high boost levels before failure.

Would it possible that if you wrap it, if the adhesion to the OEM piece is weak, the OEM piping would collapse and the "shell" would stay intact? That would be funny. Not HAHA funny though. But then again, quality resin ad-hears well

I have the stock intake manifold and intake. If you wanna pay for shipping there and back, and return it in the same condition... I could lend the community a hand. Might take me a week to get it boxed though

It would be worth considering for molding purposes.-(the shipping back and forth).

If I can't find one to sacrifice for opening up to study...lets consider this. I'd like to source one more local if possible ? Anyone ??

If the stock unit is CF sealed....there will be zero flex/swelling under boost. Therefore no plastics should crack and fall inward under vacuum.

This would be a high-end Epoxy or Vinyl-ester only project. Even if molded for boost.

the oem piece has taken upto 10lbs of boost BUT when they get warm they baloon in the middle... literally balloon...... so im guessing to wrap it would really strenghten it... plus it looks great anyway and inside its a great design, it would really work well once properly re-inforced......

Ess actually used to use the stock intake on the vt-450 kits for the early s54 kits.... Another guy from maximum PSI is heavily reseraching using the stock intake for his turbo kit.

The area which is found to balloon is certainly going to require additional steps aside from what I previously mentioned. Obviously avoiding additional weight is always a goal.

Perhaps cutting one open to study is the best start instead of just band-aid'ing the stock unit ?

Engineering a clam-shell full CF/Kevlar unit would be my choice.
