***Official ITBs Thread***

It was sort of a tongue-in-cheek question to use Hondabond. The very edge of my flange is distorted away from the head by 0.012"; either it was defective or I distorted it while installing the throttles to the flange. I'm working to get a true flange to have a proper seal.
#703
It was absolutely the installation of the throttle bodies into the flange that caused the distortion. With careful attention to the trueness of the flange, I was able to reinstall all throttle bodies, seal them, and torque them, and still have a true flange afterwards. Likely most people don't deal with this since most ITB assemblies come as fully assembled assembles. Though I was able to achieve trueness to < 0.001", I did opt to use a thin film of Hondabond at the coolant passages. No leaks, even with the 1.3bar Koyo radiator cap!

For the vacuum lines, I dug around and found a Polyurethane tubing (called Excelthane) that has a 5/8" bend radius up to the job. All lines are equal length and unkinked.

You must have torqued each bolt then rather than doing them in 30% passes? That shouldn't 'distort' the flange, but it may pinch the gasket and crate some leak paths.

Thought I would bring this thread back to life showing my cold air setup.
Pipercross plastic airbox, slightly modified with a heat gun, 4" single layer duct to a CT Icebox with CT velocity stack and filter.
Hood frame slightly modified as well.
Additional 2.5" cold air feed from the front grille
Close up shot on the air box mouth
and the cuts I made on the hood
I haven't been able to drive it yet, still waiting for spring to arrive here in Sweden but I'll update later on how it performs

Yes it's an universal airbox that fits PX600 series back plates, you can get both left and right hand entry so one of each might work for you.
I bought mine from here Pipercross - 600 Series Air Box
As base plate I use one of these (but in grp instead of cf) https://www.jenvey.co.uk/products/ac...-base-abb2-50c
Here's some more nice stuff that might be interesting https://www.reverie.ltd.uk/product_l...l&group=A_AIRB

So.... I am diving head first into an ITB build over the winter and have begun to acquire some parts. I am just trying to get some feedback on things that I might b missing in order to run ITBs reliably. My parts list is:
Hayward ITBs
Vacuum block and fittings
BC Stage 2 Cams
Mugen Header
Test Pipe
Fujitsubo Legalis R Exhaust
I plan on picking up an AEM v2 EMS to go with my UEGO
Lots of tuning...
Any feedback on any other parts would be great. I am guessing I still need new injectors, and maybe new valvetrain. I have read that the OEM valvetrain is pretty stout as it

You are going to need fuel fittings/lines and a pressure regulator.
Not sure if you can use stock TPS with the Haywards so might need a new sensor.
Keep the stock valvetrain unless there is something wrong with them.

Awesome. Thanks. Any recommendations to include injectors?
#710
It might be possible to use stock injectors but otherwise just get something with quality, unmodified Bosch EV14 for example.
Injector Dynamics is always a safe bet as well.
