Hey Chris what's been happining any up dates on the manifold?

I finally have got motivated enough to get some material to do one myself :-)

The manifold I'm making will be the same low mount design as stock .

I have found a good way to cut merges on the band saw at work

I'm using 36 nominal nominal bore pipe who's is the 3mm wall so 42 od

I'm going with 4 into one collecter ( when u examine the stock mani u will under stand why I went with the 4 instead of 6 into one )

For my merge I'm going with a 20 degree cut angle as well

The manifold will be made out of 304 ss and fully perged for maximum strength an reliability

Ideally I want to sit pretty much in exactly the same spot as factory :-)

Although There will be a lot of test fitting and trial and error

I'm hoping all goes well :-) any pointers?

Also I pulled the head off a facked rb20 I had and was gunna bolt the mani to that when welding hopefully it will suck some the heat and won't distort too much

All the best

Bejay

    • I would like to add that at least in my car, the RPM gauge shows around 200RPM above of what I can see at nistune.
    • Unless you have big cams, there is no reason for an RB to idle at any more than the stock 650. No, it is not 850, 950, or anything else. It is 650. In fact, it might even be 550. I just opened an arbitrary stock Neo file in Nistune, and this is what I see
    • I love the undertray, especially the flappy bit for easier access for serving I'm thinking of fabing up one at work for the MX5 while I still have access to the metal shop at work with a guillotine and press brake Whilst removing the plastic undertray on the MX5 isn't to hard, I love the idea of a 2 bolt flap as opposed to removing the whole thing 
    • Great thank you for that. Yeah that is the bumper and spoiler it still has i just hadn't heard of it being referred to as a aero form bumper before. Really appreciate your help.
    • A little progress; I took the opportunity of an oil change to take a sample for oil analysis, will be interesting to see how it was treated for its first 125,000klm (I know how it has been treated since :rofl:) I went with 5w40 and will see what that does for oil pressure at higher revs. Also fitted the Z1 front undertray....a little more sturdy than the plastic factory one (although I suspect it won't stop a tree stump ) Nicest thing about it really is the 2 bolt "service panel"....a gift to the oil changer compared to removing 14 bolts holding the factory tray.
