Lightbulb e46 BMW 318i M43TUB19 Individual Throttle Bodies

Hi everyone. I have a dilema. But before I get into it, a little intro....I'm keeping the e46 m43 NA & have been looking at making it as fun as possible with as little headache as possible.

Where I live response is king. Traffic is horrible but every once in a while you get semi open roads with chances to dart through traffic and get to where your going.

I recently sold my 2jz Lexus IS300 and wanted something more fuel economic but still within the sport luxury scene and the 1.9 SOHC 318 preface lift really fit the bill.

I like the looks and it's a bimmer so, win win.

NOW unto my dilema. o_O

I'm looking at a more aggressive cam, possibly a 266 or 272 & an aftermarket header with a catless exhaust system. Lighter pullys & flywheel. I'm in the process of outsourcing the parts but since I'm located in Panama City, Panama and all parts need to be imported things have been diffuclt to say the least.

So the first thing I did was buy some good tires. 245/35 19z for my 19/9.5 TSW rims. Now I find muself debating on wether to get the dbila throttle bodies with plenum from a vendor in the states vs. Purchasing in Europe or sourcing a MAFLESS ITB setup like this one from youtube.

http://m.youtube.com/index?tab=w1&de...?v=WxJADC0Slxk

I've been looking for enthusiasts and tuners that might give me an insiders look as to what may be needed for each setup.

I have many questions such as would a pre flashed chip be needed for both or would the mafless be cheaper than the dbila set up etc.

ITB work, and provide more HP and better responses but so few use them. I hope to get some useful responses from those who have worked with them.

Thanks and all the best.

Well, to me, that particular setup in the video doesnīt seem to run good. it revvs aweful.

but another thing, which i donīt really understand: you want a itb setup. so your aim should be a nice revving and light car? is that correct?

if so, why the hell did you go with such big tires and rims? when using a small engine and therefore no real torque, iīd do anything to keep the rotational masses as low as possible.

Hi Daniel, the rims came with the car and are surprisingly very light weight, in fact their lighter than my old 18/9 Lexus rims. The stance looked good so I left it alone.

I'm not looking for super car performance, if I was I'd look at an M3 or LS3 engine swap but I promised my wife that I wouldn't do anything crazy so since a happy wife = a happy life I'll just look to add some more pep to the car and keep it mostly stock.

I've done turbos and chargers and wanted to try a different build with the little engine. I've seen how responsive small displacement motors can be (albeit most were not daily drivers) but bimmers have a long history of using ITBs.

In the end I may just end up going with the cheapest option seeing as I'm limited by location and access to parts.

thanks for the chime.

JR

Well, if i were to build a na engine i would take a set of itb`s from a motorcycle, match them to a modded runners and i would use megasquirt 2 to control it.

does that engine have any kind of vanos?

Thread update. After hours and hours of searching and talking with mechanics, I've decided to go with dbila since it would require less tunning. The custome made ITB setup would require alot of tunning with the piggy back etc because it deleates the MAF. The DBILA system keeps the maf and all the bells and whistles BUT gives the response and the benefits of ITB setup. The price is so much more, but you get what you pay for.
