Post your ITB Setup
 

Hey PeliCANS,

I've been researching ITB set ups for a while on the forums, and while there are GREAT threads here, I noticed there was no single collective thread on everyones set ups. I'd like to get a general idea of what you've done to set it up, so I'll list a few things pertinent to a proper set up and we can go from there. Feel free to add extra info and of course PICTURES! This will be aimed at more of the DIY crowd than people who have systems for sale, but post what you got anyhow.


ITB source: (for example GSXR-600 TB, home-brew, Jenvey, etc.)
ECU : (Megasquirt Version 67, etc.)
Injectors Used: ( Manufacture, flow rate)
Manifold source: ( Stock weber, zenith, home-brew, etc)
Fuel Pump:
Pressure Regulator:
Ignition / Crank trigger:
Rough total cost for a running set up:

Any info you gained that wasn't on the forum.

Thanks Pelicans, hope to see some awesomeness.

sub'ed, i am working on this as well.

I compiled parts for GSXR 1300's ITB's, and I'd say I'm $600-800 in.

Already have MegaSquirt II v3.57, twin 044 pumps, stock 3.2 FPR, 80lb Deka injectors, GSF crank trigger system with 36-1 trigger wheel, VR mount, and dizzy block off.

I'm turbo, so I have to build logs atop and appropriate piping from IC.

Is there a link to some of these set ups? Thx

GSXR-1000 ITB's, VEMS ECU. Have made several sets for 993, 911 3.2, 2.7.

Last iteration is for my 2.4 S with E46 M3 electronic actuator and E46 electronic pedal (to get rid of the long throttle cable). Tested fine on the bench.

I started buying all the bits and 3D modeled my own system, but opted to go carbs. In the end, I felt that the cost was too close to carbs and that my home brew EFI will have no value to others in the end.

Beautiful Marc!

What green is that? it's strikingly similar to the Velvet Green on my 69.

Built on 911E throttles enlarged to 40mm by Eurometrix, 39mm ports. Bells are for 44mm Weber (VW). Stacks are 1/2 thick wall, then tapered to fit.

That's a 356 color "Smyrna Green"

It photographs nicely but the pics just don't do it justice! Wonderful depth and tone.

Here's mine – I'll have to check the details if anyone is interested, but basically it's a Haltech running ITBs with twin plug heads.

Here's the Rasant Engine Management kit installed on PMO 46mm ITB's

http://i72.photobucket.com/albums/i1...8FD4DBA47C.jpg

what Cerakote color was the fan and housing painted?

It's a ceramic coating. I can't recall what color, it looks like a protective coating with the natural finish. There's a guy here in So Cal that does it.

Thanks, I do fan restorations as well and use Cerakote.

I'm picking up a 2.7 RS longblock this weekend and will need Webers or an EFI/ITB system for it.

Very cool! I'll reach out to you next time we're doing one.

i swear i've seen it applied to rifles haha

I just acquired a 1997 engine in an 88 Carrera Coupe -3.6 ,with
KMS engine management and itb's-System is a KMS25
sport cams ,Rarly headers
2/2 rsr muffler w jethot coated headers and muff.

MP25 management ECU Specs are listed below-(they are big with the BMW guys)
System has been used in a exclusive use track car for the last 5-6 years with 100 % reliability.

<http://kms.vankronenburg.nl/wp-content/uploads/2012/03/01-01-01-0001prof.j
pg>

The KMS MP25 ECU is an affordable and efficient engine management system.
By using the minimum of sensors, three auxiliary outputs, one auxiliary
input and a wide range of functions, the KMS MP25 ECU can cope with 90% of
all types of Otto engines.
These basic functions make the MP25 a simple, reliable and effective
engine management system at a very competitive price.
‘This is a engine management system designed by engine people to be used
by engine people. Anyone who understands the mechanics of the Otto cycle,
should be able to set up and use this system with little difficulty.’
Features:

* Complete engine management system up to 10 cylinders
* Self-learning lambda control in combination with KMS UEGO controllers
* Engine diagnostics
* Short cut protected outputs
* Serial RS232 communication
* External dashboard (KMS CAN display in combination with interface)
* 2 engine load sensors
* Analogue input (2nd lambda, gearbox position, G-force sensor, EGT, etc.)
* 3 auxiliary outputs (Shiftlight, water-injection, cooling fan, etc.)
* Pit lane limiter (variable)
* RPM limiter
* A.L.S. (variable)
* Powershift (separate delay and cut-off time for each gear)
* Boost control
* Launch control (variable)
* Idle control

^^^^^ Not a good sign their webpage is not active!!!

It looks like the poster's error: he copied the url for a picture of their ecu but when the forum renders the page it de-linked "pg" from the end of the address which SHOULD be ".jpg." Add back the "pg" at the end and the pic of the ecu comes up properly.

I have been thinking of going with ITB's after speaking with Al about a rebuild.
At this point I have a pretty good running 3.2 (other than oil leaks) with Motronic DME.
What should I expect changing to ITB's and how would they compare to the Motronic FI currently on the car.
Thanks, Rich

Hey Al, do those S3 ITB's come polished? Is there a reason they aren't lined up and perpendicular?
I'm shopping around for a running 3.2. In the future, ITB/EFI/EMS is a definite thing.

Still not done Making the plenums and intercooler. But here is the link to mine, it's a turbo so a little different . I made my own manifolds got the ITB's from Jenevy and also the linkage.

ITBs
 

The velocity stacks do come polished or powder-coated. The ITBs are lined up, but are slanted inwards, by design, at approx 10 degrees from vertical.

they seem to be not so much into social media. Velocity stacks for the M cars are delicious.

Al that engine looks delicious. Got your email btw, going to respond shortly.

thanks....give me a shout and we can discuss.

The KMS stuff seems way legit. I had them quote me the setup, before I decided to stick with carbs and a 12 plug.

Holy smokes!! Beauty all around.. That plenum! Totally custom fabbed I assume? And that air filter.. is that something off the shelf? Very cool.

Although I am nowhere near getting my ITBs running (42mm bike throttles, Microsquirt ECU), my goals in converting from the Motronic ECU/intake on the 3.2 are: much improved throttle response, modern & mappable ECU for tuning, visual and acoustic delight, losing the archaic AFM "barn-door". The big two for me are throttle response and induction sound. My previous project was a motorcycle-engined car and although I will never get the instant throttle response of a 998cc bike motor, I am expecting to recover the ITB orchestra that is so locking with the Motronic plenum.

Ferrino, thanks for the reply.
That sounds good, I would be looking for the same characteristics.
Rich

I have been installing EFI using MFI stacks. This retains all of the factory induction for early cars. Includes flex line fuel feed like the RSR-MFI systems.

Currently building 2X 3.0s and a 2.8 with the same system. This does require MFI ports installed into the head.
