Animefun Posted August 23, 2009 Share Posted August 23, 2009 Hi I am all new to the L6 and i was just wondering what i can remove from the intake, and what everything is on it! Only thing i know is the cold start valve, everything else is just a blur of fuel lines. Im adding a picture so you guys can pin-point hwere all the different things are! Thanks -Tom Quote Link to comment Share on other sites More sharing options...
Six_Shooter Posted August 23, 2009 Share Posted August 23, 2009 I'm using a GM ECM to control my L28, so I replaced the TB with an GM 3400 TB (going to change to a 3100 TB, since it's smaller soon), and was able to remove a lot of comonents and bolt bosses that would have been on it. I mention the previous because it changed the throttle activation from linkage to cable, and set-up the fuel system a little differently than stock, going with a single (custom) fuel rail, instead of the stock looped fuel rail. What I started with: What I ended up with: And what the final assembled product looked like last year (since going to DIS I was able to flip the TB over and help "clean up" the engine bay a bit more): Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted August 23, 2009 Administrators Share Posted August 23, 2009 If you search, you will find TONS of info, dedicated threads to what can and cannot be removed and still retain all the functionality Nissan originally intended. Here are a few examples. Customer car, N-47 intake, EGR removed, stock EFI, functions 100% OE. My personal daily driver, N-42 intake, stock EFI. Only comprise made here was the elimination of the air flow regulator. Higher warm idle speed for a decent cold idle speed. My personal Race car, N-42 intake, Mega Squirt EFI and distributor-less ignition. Another customer, N-42 intake, stock EFI. Another customer, N-42 intake, WOLF V4 EFI. Another customer, ZX manifold, WOLF V4 EFI. Another customers intake I did next to a virgin intake showing various bosses removed, holes plugged etc. As I mentioned, if you search, you will find all these and others documented and even dedicated threads covering what can and cannot be removed and what affects on performance, drivability, those modification will have etc. Good luck, Paul Quote Link to comment Share on other sites More sharing options...
kolonelklink87 Posted August 23, 2009 Share Posted August 23, 2009 that zx manifold is niceeee.... Can I ask what it looks like on the inside and why the rationale of using a zx tapered manifold over a larger non-tapered unit? (or is that super-secret? ) -pete Quote Link to comment Share on other sites More sharing options...
Administrators RTz Posted August 23, 2009 Administrators Share Posted August 23, 2009 that zx manifold is niceeee.... Can I ask what it looks like on the inside and why the rationale of using a zx tapered manifold over a larger non-tapered unit? (or is that super-secret? ) It was 13 years ago when I cleaned up that manifold. I used it because it's what I had Quote Link to comment Share on other sites More sharing options...

WizardBlack Posted August 27, 2009 Share Posted August 27, 2009 Search (on google) for the EFI bible (specific to the Datsun). It will show the components and explain what each part's function is and how it does it. Quote Link to comment Share on other sites More sharing options...
