Camlob,
What are your expectations on the additional requirements / issues that the ITB could bring about? For instance, will you need to rev the engine for a little while before taking off on cold starts? Also, do they require frequent adjustments?
I am very anxious to see hear your impressions once the project is done!

Other than that I dont see an issue. I used to own a E36 M3(euro), E34 M5 and a E39 M5. They all had ITBs. BMW pretty much perfected it.

Just came back from the shop and pretty much on sched. The wiring harness from Clewett is installed but we had to use some parts of the old(actually new!) stock harness to utilize some sensors e.g. oil level etc.
The immobilizer issue cropped up so we are figuring out a way to disable it. I dont have a clue on how they will do it. This is the only roadblock that we are facing. I dont know why he asked for the old ecu. Needed a part for the immobilizer by-pass I guess.
We decided also to install a fuel pressure gauge.
The aircon hoses will be relocated next week. Cant wait to get it started and tuned.
Finally installed the DFI's. The sound insulation will also come off eventually.
EDIT: Just found out that the car ran! So tuning starts on Mon!!

Thats an incredible looking motor. Im expecting big things from this so dont let us down! I think you will be pleasantly surprised once the tuning is completed properly...
ViPEC/LINK is a New Zealand designed and manufactured product s. Its cost effective here too and plenty of experienced installers. I have the v88/Extreme being installed and tuned by one of the rally shops here in late June. New hi flow injectors and MAP sensor etc. 8 hrs Dyno and 8 hrs programming to get it right. Steves been a tremendousness help in initial maps. Target power is moderate (maybe 310-320 bhp and 270-280lbft torque) but drive ability is key. the DC cams didnt deliver their best with the factory config and induced a stalling issue with the RS LWFC, Cup dual light weight pulley and alternator hub etc. No option but after market ECU to straighten it out unfortunately....
Keep us abreast of developments,. Particularly interested in dyno data (raw rwhp etc not marked up with TCFs). AFR data would be useful too....
Cheers

Not really aiming for high hp nos but more on response. The sound will be an added plus.
Are you going alpha n or map? The tec3r has the ability to combine both.
edit. just realized you are going map.

Hi C. Yeah the DC21 with SW chip and RSLWF could be made to work I reckon. However with lighter crank and alternator pulleys and catless X pipes etc it starts to really push the nevelope on a NVR car. With Varioram it would have been fine.
The problem is simply that you can properly tune for mods like cams using a remove chip supplier. Not to gte the best from your combination of modifications. You need to tune on a dyno. The SW chip only tunes the idle and WOT settings. The partial throttle and all the other curves like idle open decell dont get touched. This is where a Motec type solution is fantastic. And it removes the slightly restrictive MAF from the set up letting more uninterupted air in as I understand it.
The DC24 cam you are using wouldnt have worked acceptably with Motronics amd LWFC on your 1994 car I do not believe so you would have been forced down the route you have actually taken.
Im using MAP although mu ecu will support either or or both. Id say you will use alpha n for ITB probably. Im still keeping my manifolds.
I never expected a LSD and camshaft install with a budget of about 8k including parts to blow out another 2500-3000 - but that seems to be the way unfortunately. If the extra cash is the only negative at the end of the day it wont be so bad...

I have a MAP sensor so it will be combination of both. Since I went the ITB route, I went for a more aggressive cam, the DC 43. Some say I could have gone even bigger with the ITBs but thought that it would have been too much for a street car. John also recommended that I limit myself to the DC 43.

UPDATE: Never knew the synchronization of throttle bodies are difficult. Thats what we are doing now and probably till tomorrow. Even with BMW's, that was an important maintenance item. It was a good thing we were able to borrow the tool needed to synchronize them.
I decided to upgrade my PLX afr dial to have two banks covered. I am adding another O2 sensor for monitoring purposes of the other bank. So I will have two afr readings! I will mount the dial in the left column. I think the dial will be able to also list exhaust gas temp. Not too sure if I need it though.

Here are some pics from todays visit. Took a vid of the car running on the base map. So its running very crude and will eventually get tuned within the end of the week. We plan to finish off everything by next week.
Tommy at Autoteknika is doing an outstanding job. Not too many people over here can do this. I am glad I decided for him to do it!
The vid.

A pic of the stance of the car with the JIC's installed.
Trumpets!
A pic of the ecu. I will mount it just at the fire wall area in the rear seat.

Very nice project!!!
Those open trumpets scare me a bit though since lots of work is still being done around the engine compartment....they're almost begging for a nut, bolt, retainer, whatever to be dropped into them accidentally. Rubber stops as found in kitchen sinks often work a treat, leaving the small chain attached makes removing them a breeze as well.
