Did anyone mounted the RHD ITB Kit on a stock LHD E30 318is ? Found a post where someone said that it does not clear the brake booster .

It fits, you just need to let them know when you order.

Mucking around with the LSD, modifying it to fit 6 clutches up from 2 clutches!

Still working on the cams and ECU results, off to a dyno tomorrow!

So I got my ECU and cams installed and the power output was wild! I've got a bit more work to do before I share results, but damn, good fun!

Once i get it all in, engine wiring loom made and have it mapped i will pop back with some pictures and the numbers from the Dyno.!

I'm looking forward to it!

I've been busy myself, I've got some cams, doing some work on a head and I've started rebuilding a bunch of small case LSDs! I'm redesigning parts for them to make them fully customisable!

Why did you terminate the project?

I started working with BDS motorsport.

Aw geez, good luck with dealing with Bruno. I've had nothing but trouble with that guy, and not just me! He is someone who knows how to get results because he has experience, but the downside is that you need to deal with him.

Oh that is super cool!

Getting a stand alone ECU would probably be the easiest way forward. RHD also has a plug and play ECU kit, and you can get quite a lot from these cars with a tune!

It is just a manual gearbox, I'm sure that an experienced shop could make it work.

Sharing is caring, as soon as I get a response you'll know!

I needed to email them every day for a few days to get a reply, so I imagine it will be like that again.


I don't suppose anyone knows what the maximum lift the OEM M44 can handle before I start bending valves?

You're exactly on point about my thoughts. It is all well and good to get a bit of gain, but at what cost? I mean that is why I did the ITB kit the way I did, I wanted a car that drove better overall.

I had a look at page 12 - are you running 11.4mm of lift with the OEM pistons?

The problem with cams is that there is no real academic way to predict the engine behaviour. There are good modelling and simulation tools these days but in reality they're an indication at best. As best I can tell, the OEM and aftermarket cams that are designed for the road are actually all relatively long duration, I stand by what I thought when I initially started this thread that BMW intentionally detuned this engine.

I think what catcams are doing with their sport cams is that they reduce the total duration on the exhaust, and increase it on the intake, but the ramp is increased so it has the same 'effective duration @1mm'. In that case they're making the cams more aggressive, but with less overlap so they're preserving idle and low end. If this is the case, the improvement comes mostly from higher lift from the intake cam. After speaking to cat cams, they have another set of cams they sell inbetween the sport and track cams, and the data sheet for is the only one of their street cams that has more overlap than the OEM cams, so I think that will be the one that takes off when it revs up with a bit of trade off in the low end since it is the only one that will crossflow more than the OEM. Because the OEM cam gears are slotted you could in theory run a couple of different combinations of cams and then change the timing anyway to change your torque curve. So again, I wish I could print some money like the reserve banks of the world and just do some testing!

I've asked catcams for a few more details about their cam setups, see if they have any modelling or results they can share, and then I'll make a decision. I'm leaning towards the more aggressive intake cam, and then clocking the OEM exhaust until I'm at a point where I'm happy with the amount of idle quality I'm sacrificing for the move in the power curve.

So I've been enquiring about different cam options, and I got to speak to a fellow who is running a car for a race series in Queensland and what he has done is counter to all the rumours and unfinished threads that I've seen around. He has 230whp - about 280 at the crank! He is running E85, with 10.5:1 compression with a 290 degree intake cam with 13mm of lift. I've seen a video and a dyno and the car is actually making that power and pulls hard. What surprised me is the head is stock springs and retainers and is redlining at 8200RPM. This runs pretty counter to everything I've heard about the building these engines.

I'm currently thinking of getting a cam for the intake and possibly leaving the OEM exhaust cam. Most of the 'sports cams' that I've looked at are either the same or less degree than the OEM exhaust cam, the only thing that changes is lift. This is where I really wish I had a bit more money to throw at a project, there will be an ideal point for exhaust lift just like there is with intake lift, but generally speaking it is less than the intake lift and I would just like to mix and match cams and get a result. There are pretty good odds the OEM exhaust cam is already close to ideal. I really wish there were a bit more info or dyno results on people trying these things, not just talk about what people have tried!

Thanks for all that! I'll contact all those people and go from there!

My whole reason for wanting to keep the OEM ECU is that just changing the intake and exhaust doesn't really justify buying a stand alone ecu and then paying for the tuning time. That said, the kit as you buy it plus a tune gets ~100wkW (I've seen the dyno results from Rama). But considering it will just be adjusting some timing being able to reflash the OEM ECU would be sufficient.

If I go standalone though I want to make it worth my while so yeah, may as well go some cams and get over that triple digit!

Well it has been a while since I've looked at anything on this project, and I'm actually revisiting it!

I'm going to be redesigning the 3D printing intake, and so I'll be selling the 3D printed parts and the aluminum runners, if you're interested let me know!

I've also enquired about reflashing the ECU with different people over time and still haven't been able to find anyone who can guide me or do it. I tried Midnight Tuning some time ago, but that was a no. I contacted Powerchip (Wayne Besanko) but to be honest, I just never trusted the guy, and I'm trying one place in the UK that seems to have started doing it relatively recently but I'm not holding out much hope. I also ended up chatting with Bruno DaSilva (BDS Motorsport) and holy hell, what an absolute crack head that guy is! I don't know why these cars attract whackos to work on them but he is absolutely the worst I've come across, so if you ever risk dealing with the guy, don't!

I'm considering getting a stand alone ECU finally, and to justify it I'm wanting to get some cams or adjust the OEM cam. Has anyone done either of those and has any experience to share?

Keep track with what I'm doing on youtube! https://www.youtube.com/user/ShiftMotoring?app=desktop

Great to hear that it's still running!

I sent you a private message back in Sept. Did you get it?

Cheers,
~Ralph

Just had a look! I'll add it to the list when I get a chance!

I haven't done much on my car for a few years so haven't been as active on the forums. I discovered a few days ago that C5 Corvette Calipers (available on Holden cars here) are a direct bolt on up front, so was going to give those a crack and jumped on to have a search and see if anyone had tried it.

After all this time - I've still not found anyone who can reflash the ECU, and I can't justify the costs of a standalone ECU and tune!

Car is still running healthy after all these years, and it has done tens of thousands of kilometres since installation!
