madkaw Posted December 21, 2023 Share Posted December 21, 2023 (edited) Custom Datsun/Nissan L6 intake manifold with fuel rail and and BBK throttle body with TPS. Built on a Cannon intake manifold this custom intake manifold should bolt to any L6 cylinder head . I ran this manifold on a N47 head with injector cut outs on the head with no issues - just need to use proper gasket . Mates up with early heads with no injector cut outs also . Runners are 37mm at the head surface tapering up to 44mm at the manifold plenum . BBK throttle body is 75mm . I used cable linkage mounted to black stand off bracket in the pic . Injector bungs are for 14mm injectors . Custom fuel rail fitted with this manifold has 1/4 NPT threads at the ends with 5/16” nipples currently . Manifold has 3 vacuum ports at the end and also PCV on the bottom of the plenum . Cannon mounting flanges at head are standard thickness and do not require step washers . My project is moving a different direction and selling off parts that I will no longer be using . No defects with this manifold . I smoothed welds and polished the top surfaces only since that’s all that’s visible . There is heat wrap on runner on bottom sides to protect against heat . I had no issues and this manifold performed great. asking 500$ plus shipping PM or sfinnerty1018@gmail.com Edited December 21, 2023 by madkaw Quote Link to comment Share on other sites More sharing options...
calZ Posted December 22, 2023 Share Posted December 22, 2023 What are you swapping to? I thought you were running this now Quote Link to comment Share on other sites More sharing options...
DuffyMahoney Posted December 22, 2023 Share Posted December 22, 2023 Sad, that is 10x better looking then the protunez. Quote Link to comment Share on other sites More sharing options...

I might actually go that direction . The runners on this intake are a little too short for where I want my power band . I could fix that but I really don’t want to do all that work. Too many other things going on . If I wanted to go turbo it would probably be fine - but I doubt I’ll go that direction - ever Quote Link to comment Share on other sites More sharing options...

I don't think so, and it looks like it would have 1st cylinder air distribution problems compared to ProtunerZ's... Quote Link to comment Share on other sites More sharing options...

I think the protunerz intake was an opportunity to make something extremely sexy and perform well, but the intake runners look like home depot pipe, then the rest looks fine. But it could have been amazing. Quote Link to comment Share on other sites More sharing options...

I'd rather have performance over looks and I don't like the angles I saw for the first cylinders. Quote Link to comment Share on other sites More sharing options...

This has less of an angle change from the TB to the port and a longer radius on the plenum than the Protunerz intake.

I just think it would have been sexier for sure. Quote Link to comment Share on other sites More sharing options...
madkaw Posted December 29, 2023 Author Share Posted December 29, 2023 As far as all the comments about air distribution - you would be entertained watching my two widebands - that separate 1-3 cyl and 4-6 cyl . I think any log style where the air comes in from one end will have some distribution issues under high vacuum situations . The important thing is that under load the air distribution is even . Thinking about modifying my diesel intake next . Be cool to have air enter the center of the plenum and see what affects that has on air distribution.
