THat exhaust is beatifull. Burns collectors and megaphones? I would be interested to see a pick of the Manifold. Was actually discussing triple SU's on a JZED head with another member a few weeks ago. Cheers.

Interesting, does the inside transition from the round back of the carb to a square as quickly as it looks from that pick or have you filled it inside somehow?

Very happy ,i think we can go quicker .

No infill in the corner of the manifold ,but very close.

New manifold will have a plenum.

I love this setup- I saw pics of this from FB as the manifold was getting built... I like the idea of SUs on the JZED- just something different. I also thought that the SUs could help speed up the air through the big JZED ports at lower rpm, which could help with torque. Just pondering though- could be wrong. Most run 48DCOEs with JZEDs, with probably 42mm chokes, which would not be great down low but would go well from about 5000 and up
