M42/M44 ITB Kit Design

[GJa003]

I would be interested in E30 Spec'd one depending on price

On a side note, i appreciate all the effort you & Rama put into developing these kits, its whats motivated me to build a 2.1L M42 for it.
Picked up a spare engine last night !!

I would be interested in the group buy for a e30 fitment also.

Is that baunGTs plenum?

Awesome, I think he wanted 4 as his minimum but I'll let him know that there is some interest!

I actually don't know  I know two people have been fitting this kit to an E30, one of them (in Germany) was happy to resolve fitment themselves and this one had a few other issues which is why it was sent back for Rama to work on. I'm not sure on the details, but I think that the owner lives in QLD...? Maybe? Anyway, I told him to take some pictures so that people could see what was involved in getting a clean fit in an E30 with the standard kit.

Interested in a group buy.
Any idea if a booster eliminator would allow the standard/unmodified airbox on a LHD e30?

I love the ITB kit and design and would possibly be interested in the kit. LHD e30 here. Love the RHD flywheel I have, think this would be a nice addition someday

If you want to remove the booster you could quite possibly fit a small man playing a ukulele in the engine bay as well. So, yes. You could fit the standard kit!

Alright that is four showing interest!

I've asked Rama how he wants to organise the group purchase for price and kit variations etc, in the meantime you can PM me with your fitment details and location! No commitment yet, just trying to get organised so message me and we'll see if we can make everyone happy with pricing and fitment etc.

I'm really interested in this kit so I emailed info@racehead.com.au but I got a bounce back that the email didn't work.



I'm based in Canada and I have a LHD 1991 e30 318is so I'm very interested in this kit.

1) I'm in for a group buy but would also be happy to work with you on measuring for a custom 3d printed airbox.

2) What ECU should I run? Stock ok?

3) I need to replace my exhaust. Did you figure out what diameter works best?

Thanks for putting in the time to get this kit developed for us m42 guys

1) I'll let Rama know that you're interested in doing a custom airbox. Before you make up your mind, keep in mind that there will be a delay between you fitting the kit - then measuring up your airbox - posting me a foam plug - it getting modelled - you printing it - and then driving your car. It could be 1~2 months before you can drive the car again. It can be done though - I designed my 3D printed box while I was ~3000kms away from my car from pictures and measurements my friend sent me.

2) Stock ECU will work fine, a custom tuned ECU will work much better and a stand-alone ECU will be ideal.

3) If you're keeping it on the road - stock diameter (2" or 1.75" ID I think it was) is the most sensible choice. You will get much less drone, and a more usable power curve in the low RPM. If you go up, you will get a bit more peak power, but you will lose area under the curve in the low RPM. If you want more power but same street use, use the ITB kit as shipped, and the stock exhaust diameter with a straight muffler and high-flow cat, if you want more power and a peaky drive - go up half an inch from stock and shorten the ITB kit!

Send me a PM so that I know who to message once I get the group buy sorted.

[lambertius]

Please PM me if you're interested. Price will depend on the number of serious purchases. Let me know you car and driving side, whether you want the CF of FG airbox, what country you're in and if you want a flywheel as well. Cut-off date is the 31st of May 2016

I just thought that I should update you on the kits reliability  - only thought of it after I got a question in PM.

I've made this trip once, but will be driving back up to Sydney at the end of this month https://goo.gl/maps/7Ms9qQZKtst

And I've made this trip at least 6 times https://goo.gl/maps/mLTcNAdM8Pp

As you can see it is a very substantial distance. Other than having my ears bleed from the after market muffler until I put the stock one back on, there have been no issues. Fuel economy when driving normally is still the same as it had been previously (~6.5L/100km on the freeway, ~11L/100km around town ~9.3L/100km regular driving)

Since there is no where to legally test the top speed of a car on that trip, I can't really comment on whether it will crack 200km/hr and be limited by the final gear on top speed. If I were to ever drive to the Northern Territory however...

Alright - and interesting development on the tuning front.

I have finally found someone who seems interested in not only tuning my car, but writing a tune that can be sold. This isn't a certainty yet. Below is the email I sent them:

Thanks for the chat earlier.

You'll find the dyno with the AFR in the first post:

http://www.m42club.com/forum/index.php?topic=18442.0

It is quite long, so I'm not expecting you to read everything!

This post http://www.m42club.com/forum/index.php?topic=18442.msg130215#msg130215 compares a few other combinations with different cars. I also cover some of the assumptions made as it isn't a strictly 1:1 comparison, but it does demonstrate the overall improvements from the intake system.

I don't sell the kit and I don't have any financial interest in it. I'm friends with the manufacturer, and I worked with him to develop the kit for M42/4 cars. I sought out someone to help me design it because I don't like unproven parts. The same thing goes for getting a tune - which is why I haven't done it already.

I'm currently organising a group buy for the kit - some people have the M42 engine as well, and I know at least some of them would be interested in a matching tune.

My questions regarding the tune would be:

1. Can you test it to show me before and after results on my vehicle?
2. What do you change in a tune?
3. What differences would you have between your standard tune and customising it (this is assuming that the induction kit makes enough difference to make your standard tune non-viable)?
3. The ECU currently is quite capable of adjusting itself so that I can change muffler for a street and track muffler - will it still be able to do that?
4. And regarding others - will your tune be able to work with overseas models?

At this point, they seemed interested in looking into the details of the kit and the thread. No one ever responds to email, but I have finally found some time to call people and follow up. I thought that with organising a group buy I would put in some renewed effort as it would compliment a setup if a tune makes a demonstrable difference.

I'm generally pretty skeptical about chip tunes, especially regarding claims with stock NA motors. This guy seemed keen to demonstrate that his stuff worked so I'll at least follow it up!

[lambertius]

The final episode is up! I hope you enjoy it, I start talking about the kit about half way through. We tried to be as gratuitous as possible with the induction and exhaust sounds!

Thanks for getting back to me on this. I've PMd you about my interest in the group buy. As the car is my daily, I think I'll just have to go with the modified stock airbox (FRP) with curved trumpet.

Hello everyone,

Im a newbie here, Im orginally from the 318ti.org group and found this forum with the itbs!
so have joined M42club forum to get more informations.

just wanna say that lambertius has done a great R&D work!!
I have read this forum over and over, which conveinced me to order the ITB kit from RHD engineering few weeks back from Rama.

first I will go with the original DME with MAF, even though my DME is tuned by Kelleners.
also I plan to install the Apexi AFC so can play with air/fuel mixtures.
eventually when I have enough money to spend, want to go with stand alone ECU and have no MAF and open throttle bodies for that roar sound!!

unfortunately when I recieved the kit, it had some packaging/shipping issues where the 2 trumpets were deformed.

and also found few defects and wrong parts so its on hold for now.....
Rama is doing his best to provide me with correct and updated parts now, but abit unsatisfied since I had to pay for the return shipping costs.

Im a bit concerned once I install them for any other issues?

did anyone purchase and already installed them?


lambertius,  I have few questions so I can be ready for installation once I get the parts.

1. do I need the synchronizer tool for adjustments?
    as I look at the itbs, I do not see any individual adjustments.
    only adjustments for each manifold so 2 itb at same time
2. where does the large vacuum hose coming from the valve cover connect to?
     do I make a hole in the air box plenum?
3. also the vacuum hose coming from the fuel injectors, 4 into 1 large hose, where to connect?
     do I make a hole in the air box plenum?
4. how do I connect the ICV vacuum hoses?
    I got a block to fit the ICV with 2 holes, assume one is connected to the vacuum block but where does the other connect to?
5. biggest concern right now is the manifold ports in the fuel injector ports.
    I have not confirmed with my car yet but I have one phenolic gasket in hand so confirmed the shape and alignments.
    the ports align but the fuel injector ports are much smaller on your design so it will have a leak?  maybe the phenolic gaskets could be wrong design but I will confirm once I get the BMW gaskets this weekend.



my car is '98 318ti M44 Right Hand drive so assume its same/similar as your 318is.

thanks,
