20b Xcessive lower intake manifold vs stock question
I have a question to you guys that have the 20b Xcessive lower intake manifold.
The thing i need an answer to is if the xcessive lower LIM moves the UIM forward or backward compered to the stock one?
I had the xcessive 13b LIM on my 13b and it moved the UIM forward. I'am planing to move my 20b as far back as possible so i need to know if it moves the UIM.
posting a picture of the two.

I was hoping to get the engine just behind the steering rack so i can lower it to the same higth the stock 13b is sitting.
So the 38mm lower xcessive intake will help since the firewall tapers back around the tunnel like you say.
I have been looking at your thread and you must have moved the engine even further back?
If my mesurements are correct i have to move the engine back 13cm to clear the rack.

I tried to keep it at 3-5 degrees. Truth is, I don't think it matters. It would depend on your chassis strength and the more importantly how you measure it. It's hard to measure it. The casings aren't square. OEM rubber coated frame is hard to get straight edge on. Just eyeball it straight using stock mounting holes as index. If you need that 5hp extra that would come from the perfect chassis flex at particular torque output which would line up your transmission and differential perfectly, just turn up the boost half a psi.
