New ITB's for the E30/E36 Chassis's

Guys:

Not here to sell, just get some "intelligent" input! We just picked up a 95 325is Test bed to do an ITB Conversion on! Also have a e30 325is with E36/2.8 Turbo being built so the itb set-up will fit both chassis's!

Some General notes and parameters:
1. 45mm ITB's Fully Anodized and Stainless
2. Tig Welded Manifolds at first, cast to follow depend on interest!
3. 1/2" Radiused Airhorns built into the Plenum Base plate, to smooth air flow into intake tract.
4. Integrated into the stock ECU, with 3.5 MAF and Chip!
5. Plenum inlet is 90mm. may be center fed, or end fed not sure yet.
6. Turbo is running o34 stand alone.
7. 2 staged injection optional with Injector Bridges.
8. ITB's are modular and will allow length tuning for different engine/torque set-ups.
9. Modular design will allow Throttle plate/Injector to Valve Tuning as well!

Target price range:
$500 Manifold
$1249 6 ITB set-up.
$150 Linkage Set-up
$599 Plenum and Base Plate.
$500 MAF and Chip

Parts above will be sold seperate, for Stand alone users or those who can build their own complimentary parts to save JACK!

Lot's of Info on our Extrudabody website with past installs ETC. Please be patient with us as this could be months in the Making!

The Pictures below are some of our work!

Thanks!
Kevin

Guys:

Is there no interest in ITB's at all for the 325 motors in the E36 chassis?

From an honest perspective, you can put a turbo on an engine for just about the same price range and have the capacity for more power.

Understand your point, but Turbo is not always the best answer, ask any one on an Autocross Track or a road racer.

Also who says you can't have both?

Yeah, agreed. In any case, sticker shock is what makes my interest fade. As ridiculously awesome the response of ITBs on this engine would be, I'd have to be competing to justify the cost. I haven't seen more tha a couple road race cars on here.

I'll agree with you on that. Heck, I'd even say the ITB combined with the turbo would add a good amount of performance. In my opinion, an ITB is the first place to go before getting a turbo, but I also think a turbo is one of the last mods to do, in general.

With that, I'd say I'm very interested, but I'm still paying off college loans and $70,000 of pilot school. With that, there isn't much room for a few thousand on an ITB upgrade. Perhaps you'll be further along in the process when I'm ready to drop that kind of money.

As one last point, I'd say you should offer it in black, too. I know we could all paint it ourselves, but just as a matter of perception, it might be more marketable. I don't have facts, and those who are buying an ITB aren't really looking for ęsthetics, but if someone looks at it and thinks "wow, I like how that looks" they're more inclined to buy it. If they're thinking "the rest of my engine is black and I want this to be black" they'll be thinking of the work that will be added to the already intensive ITB install. Again, it's completely superficial for a crowd that generally isn't superficial, but it's just a thought.

Keep us updated, even if it is only a few of us.

Guys:

I am not here to debate Turbo over ITB's just not my intention! If you want a Turbo then by all means go get you one! That's just not what we are about although we are Turbo Ready, and we have several Turbo/ITB set-ups being built as we speak!

Our Intentions is to have a Bolt on ITB system for those who want them, they want to keep their Cruise Control and wants a linear Torque Curve!

We are exploring a way of Loosing the MAF sensor all together, while still running the Stock ECU as well!

Well we hate to speculate and be high or low, so we are just doing this as R&D to see what we can get out of the 2.5ltr motor, and we will post results as they happen!

We know the ITB's are capable of flowing up to 292cfm each so if the MAF elimination works as the Manufacturer claims, we may all be a little surprised what the 2.5ltr will do in N/A Mode!

Nothing like the sound of a set of ITB's on a 6 Cylinder Motor!

Hey Pirate-Copy:

Please give me an HONEST Total Cost for this? K&N 57i Gen 2 CAI - Superchiped - Mongoose Exhaust - NGK Iridium IX plugs - Quickshift - EBC Red Stuffs - EBC Turbogroove Discs - Royal Purple Oil - JL Audio 6x9's - Pioneer MP3 Headunit - Pioneer 720W Amp

If the MAF Eliminator Technology works the Plenum and MAF Parts will not be Needed, so it would be less than $2k and will bolt on to your 2.8ltr M3!

Kevin

Well all I can say is Quality and Fitment never comes Cheap, if it does you end up with Issues that leave you beside the road! Is there a big difference between the $3k Turbo kits out there, as compared to the $500 Kits on Ebay? The Largest difference is you have a Company to stand behind the Parts!

Below is the Kit we just finished for the Nissan Patrol 4.8ltr I6 Motors!

The kit below was $1900 RETAIL out the door to the Customer! Which included the Optional Vacuum Resevoir, and the Extrudabody "Silky Smooth tm" Jack Shaft Linkage set-up!

Making the BMW Kit work without a Plenum and MAF sensor is the key to keeping the cost down and below $2k

Quality certianly looks good. If the cost can be held below 2k, and the numbers look really good, then this might be something I am interested in.

One question though, how much would it cost for someone to install something like this if I was not able to do it myself. And will it throw any codes on an OBDII car?

Those 2 questions are great questions, and honestly we are not sure on the Install cost, but if you can change an intake manifold Gasket, then I don't see why a customer couldn't accomplish this conversion!

From a DIY perspective the more you do yourself the Cheaper it gets, and the opposite is also true!

When this set-up hits the market, it will not throw codes, or it will not be offered as a kit or it will be offered with a Plenum and MAF connections and a upgraded CHIP!!

We also are looking at partnering with a Company that has built 428hp N/A M3 motors, but this was with our competitors 48mm ITB's, and they used Standalone with Variable Vanos Control not like the On/Off Vanos Control strategy that Motec uses! This ECU is used extensively in Europe on Formula/Rally/Prototype cars!

This has nothing to do with our Eco-build here, but just good info for the future!

Need a Male connector for the MAF Plug!
