    16V 4age to quad throttle manifold


    Thought I would give people a bit of an advanced notice on what I might be able to offer soon enough.

    These are manifolds to bolt 20V silvertop quad throttles on to a 16V, with both big and smallport versions made available. I only want to release a product that's actually finished and doesn't require further mods. No porting the inside to get rid of the sharp edges, enlarging or adding extra barbs for vacuum, drilling the flange to suit the factory dowels in the head, grinding to suit the most common type of 4age water pipe out there or anything else that people shouldn't have to do to a brand new product.


    If everything works out here are the features these will end up with:

    - CNC milled flanges on head and for the throttles

    - 2 x CNC milled braces between the above (one of these shown in blue in the pic)

    - Molded and angled carbon fiber tubes

    - (Long enough to clear both front and rear wheel drive water pipes with the throttles the right way up) Update: no longer likely as the linkage doesn't clear

    - Curved up for more clearance off the velocity stacks

    - Enough individual ports for the following: 2 x brake booster, 4 x map and 1 x fuel reg

    - Ideal port match on both ends

    - no cheated bends or sudden changes anywhere, all with curves for max flow

    - specifically applied finish on the inside of the tubes for maximum air speed




    Even with only some of these features these manifolds would be completely superior to anything else out there and if all goes well even a lower price compared to any other product once delivered.


    In the pics below the pictured 3D model is a very early version and it's rather incomplete. In the pic the front flange is only joined #1 to #2 when later it will join all of the throttles. Also the blue brace will likely also be between #3 and #4 as well.

    If all my plans work out this may available in as soon as 4 to 8 weeks

    Estimated price: $320



    any questions?

    Awesome sounding product Sam, and a very reasonable price. I'm definitely in for one of these and your billet stacks pending final prices.

    Things are looking promising

    I did a test fit and without a custom throttle linkage there is no way to make these clear the RWD water pipe with the throttle the right way up. At this stage I am looking into making the option of the throttles being able to be put in either position if the holes don't overlap. I will find out. The R&D continues.

    One advantage of the upside down throttle mounting in an AE86 is a RHD AE86 accelerator cable will reach the linkage( a little tight maybe) or an AE101/111 cable which is 2" longer

    I tired it in the model and having the option of either direction stuffs up my vacuum port design. Oh well this is R&D for you.

    I wanted to go away from upside down throttles for this very reason, I found that with a T3 manifold the cable had 2 tight bends and there was no more throttle feel left at all, it was a stiff unresponsive pedal. Although I may have an indirect solution for this yet though.

    You could try make up a new linkage lever like the RS Chita one available for the 20Vs

    I could and I did think of that but that means I would have to supply that with every kit and add another $100 to it. Then I am sure many people would just see the final price more than anything else. I am facing this in other areas too for example do I include all the barbs and fittings, many won't know that they no longer need a vacuum block but they do see the manifold's price when it's $30 more, even if it is cheaper than the alternative.

    DIY silvertop ITB's to 16V smallport in an AE86...





    Ended up a bit close to the clutch master and brake booster, but I did manage to get an ITG sausage filter installed. Cleared everything else no worries. Making them for a bigport would be a bit more dicking around, mainly as I don't think you could just take a piece of round tube and squeeze the end.

    That's really neat, it sure doesn't look DIY so take that as a compliment.

    You're completely right about the issues with adapting to the bigport opening. This is the reason why I have not gone down this option. To help me understand what to do myself I would like to know why you ended up deciding to angle it upwards if you wouldn't like to share?
