Looks good, did you make it?

You'll want to protect the surrounding hoses and whatnot from your stainless feed line.

I thought intake manifolds are only useful in the 275+ hp range.

Judging by the welds and pieces, its the BEGI one. Did they fix the fuel rail issue on yours? Are your injectors sealing okay?

Can you take a closer shot of your fuel rail mounts on the IM?

HAHAH, ok. It is the BEGI one but we had to get alot of work done to it before we could install it, as it was a test manifold from BEGI and needed additional finishing work. We also installed Pistons, and Rods and were just shy of 300hp to the wheels at 21psi. From the previous dyno sheet I posted, we only changed manifold, pistons and rods. HA only...

Could you possibly elaborate on the work done to it before installing it? Are you experiencing vacuum leaks in the fuel bungs? were the fuel rail mounting points spaced improperly?

1. Both the throttle body and the intake manifold runner plate had to be milled flat, eighth of an inch.

2. Epoxy filler had to be used in order to raise the runners to match the head ports.

3. Throttle body and Intake runners needed to be ported and matched.

At a cost of $260
But you have to understand this product was shipped to me as a prototype and I believe BEGi intend to make their finished product of much higher quality. So far the car is running strong.

Yes, I'm aware its a prototype, as I have the same one installed on my car. I am just curious if you are running into the same issues I did, and if they actually corrected them.



I had fitment issues with the fuel rail, as well as the injector bungs. What was your reasoning for retaining the 55mm TB?

No fuel rail or injector bung problems so far. I have the TT fuel rail and had problems with this rail before I installed the manifold but none since installing new manifold. As far as the throttle body goes I did not want to spend any additional money on it right now. I am ordering larger Injectors so I will prob swap it out then.

Did you have to re-tune much for the intake manifold swap?
