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

    • Actually, if having and keeping the stock ECU is the plan, the correct answer is to put Nistune into the ECU and improve the situation, not just look at it.
    • Wrong side of sydney for me coming from Goulburn, but you should head along, all ages of Skylines will be very welcome
    • Yeah so physically that port is consult not OBD2, but also be aware that "JODB" is not really a thing - it came in around 2000(ish) but is not a standard like ODB is, each manufacturer had differences. If you are looking at ECU only and have a standard ECU, go with Datascan as Turbo Tapin said. Per another recent discussion here thought that won't do other systems like in a modern car, for example bleeding ABS
    • They're not rebuilt Racepace items. They were mint. From memory the were ex display stock that I bought off yahoo and he ran....from memory he barely used the REs when he replaced them with a set of Tein RS If have been stored correctly and not leaked fluid then they will be mint   As an observation the Racebuilt rebuilt Tein RA/RE/RS were a better street/club/track package. Really nice on the street and did good numbers at the track.  I think the factory Teins wont match the Racepace valving on the street but would be in the same window of performance on the track... albeit firmer
