hello  lambertius,

thanks for the reply.

I have followed your simple C/M by removing the PCV valve and the hose which was connected to my addtional vacuum block, then adding small air filter on the oil catch tank.

now its running like normal, idles fine and AF is jumping around 14.3 to 14.9, just like before.
no more rough idle and very high lean mixtures

so assume the PCV valve was not working well with this unstable/weak vacuum!!!

now I will drive for couple of days for my DME to reset and have it study the current setup.
after that I will read the A/F with innovate LM2 and play with air/fuel mixtures with AFC-neo, sub-computer thingy and hopefully make it much better, sort of like step 2 or phase 2.

here is my addition of the extra vacuum block
just adding extra ports on all ports
then adding extra aluminium block to attach now is only the brake booster as the breather hose w/pcv is removed

now that is working order, I may just follow Rama's instructions and delete the second vacuum block!?
and add a small sealed container to be added before the brake booster connection to make the vacuum stable? dont know if it will work or not?


so I believe now, this kit will fit the RHD with battery upfront, RHD and LHD M42/M44 vehicles!!!
ALL E36 318is/ti will fit!!!

next I will paint the engine valve cover dark grey and hydrographic with carbon to match the carbon air box.

now while its still studying, under normal driving (small/half throttle) is kind of dull compared to before.....however when its WOT its a totally different engine!!
it feels more torque and power all thru the powerband
and anywhere its very very  responsive engine, I need to adjust since its too responsive my driving feels jerky with throttle on/off......hahaha

I believe once Japan's hot summer ends and becomes more cooler it will be more lively engine

I am really satisfied with this kit!!

hello  lambertius,


so finally I had some time to install my kit during my summer break!!
it took about 2.5 days working from 9am to 8pm.

most of the time was taken for the reworking wiring harness and thinking of the vacuum hose layouts.

and the last most difficult part was putting on the carbon airbox, the bottom and most rear bolts took me many hours to tightening down.
after confirming with rama, to take out the assembly and put the air box together then put everything back......thats the way I did initially not knowing but just couldnt do it so, anyways its all in there with right hand drivin 318ti which has the battery up front.

I really like the sound and the engine responses!!!!!

I have 2 questions.

1. I made extra vacuum block coming from each cylinder to attach the brake booster and the crankcase breather.
    the crankcase breather I have attached PCV valve --> oil catch tank --> to the vacuum block
   is this setup bad? or creating vacuum leak?
   for past few days of driving, I do not have any oil leaks like your intial setup where pressure was build up.
   
reason why Im asking is I have very high lean air/fuel mixture during idle only.

Countermeasures
C/M1: should I delete the PCV valve and just connect with oil catch tank and to the vaccum block?

C/M2: keep current setup but instead of vacuum block (unstable vacuum?) go directly to the one of the manifold ports like you did with your brake booster?

C/M3: delete the PCV valve and after the oil catch tank put a small airfilter?

I would like to return the hose into the engine for regulations.....
I would appricate your advice

thanks in advance,

Hello lambertius,

sorry one more question.
what size hose connector did you use to connect the coolant hoses from the pvc?
ID 16.0mm?

thanks,

Hello lambertius,

thanks for the reply!

i think im ready to put them on!!
just need to wait for Rama to send out the replacements.....

i may ask more questions during the installations!?

its becoming somewhat a trend in my area to have AE111 itbs on 318is so i wanted somewhat different and love carbon stuff so this was the best way for me.

Hello lambertius

thanks for the reply!

1. ok so no necessity to purchase the synchronizter tool.
2. so CCV can be left all alone open? or should I keep the original PCV valve on and leave it open?
    guess best is to try to connect back to the manifold behind the throttle body, right?
3. ok
4. ok, does it matter wether the two ports goes to the vacuum block and to the airbox?
    as I think the block I got is different from yours which has 2 separate holes not connected to each other, separate air space. which each holes goes directly to the each of the ICV holes so wondering if left/right holes has different functions or not?
   as the original it is hooked up to the same open vacuum area.
5. ok, will just wait for the intake gasket and used manifold to arrive for checking.

NEW question

6. in your setup write up, the brake booster line needs to be connected separately to the one cylinder manifold.
    should not be connected inline with the vaccuum block.
    but Rama's instructions shows to connect inline to one of the 4 lines thats coming from each of cylinder manifolds to the vacuum block with the T fittings.
     is this OK? since its connected to the one cylinder manifold and not to the end of the vacuum block?

cant wait to get the correct/updated parts!!
i guess I should dyno before the installations..... 
but I am more interested in high revving engine response and the sound of NA engine!

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,
