    I got a 4ac bypass pipe from Toyota a few days ago I will check the length tonight. Also I thought the 7afe were all like the fwd 4axx with a remote thermostat housing and it wouldn't have a metal pipe ( could be. Wrong ) I will have a look at that when I get home too

    yeah 7afe is a fwd water pump and doesnt have bypass. but if oyu read the build again you will see that they said to use the rwd water pump. you need to use the rwd pump setup becuase you arent using the fwd head.

    remember the fwd water pump goes directly to the head above where the pump is.

    IExactly that...i should stop assuming ppl use the 16v rwd water pump setup as i did...

    So to rephase, 16v waterpump with 7a block the bypass pipe is 70mm with an outlet spacer 10mm thick..

    Easier ways to do it, but mine achieves a perfect 100% oem look..

    here is a pic of mine dummy fitted to check what needed to be done

    parts i am using
    -rwd water pump setup
    -16v head with rwd top outlet

    its close but not close enough


    its not the best pi but you get the idea it is very close but just wont work imo lol
    the dyno pull to 300rwkw

    BT20v is making 300rwkw like i said i would without nitrous so now its time for some spray and see if she will run a 10s or less

    is that a 4ac pipe or a 4ag pipe?

    it also looks like the outlets dont line up even if it was long enough. or is the pipe not sitting straight?

    Got around to checking the 4ac bypass pipe and it is 68mm tip to tip.

    it shouldn't...

    as already said, the outlet needs to be spaced out 10mm for the bypass pipe to line up correctly...

    judging by the measurements of the 4ac bypass pipe by davidgarratt it should be fine as the one i had made up was 70mm...

    i do have a outlet spacer to suit 16v here with gaskets...would gladly sell it...

    havent got any pics of my setup 20v 7a with rwd water pump set up rschita outlet, prolly wont have the time to do so til after new years now...

    So what bypass pipe?

    I want like 11.5 compression with slightly oversize pistons.

    What would people recommend?

    Seems to be sweet to run on stock ecu?

    Why such high compression? There's no need unless running big cams to utilize the comp. Stock ecu should run a fairly stock 7age not one with some work but.

    compression isnt all that high considering ae111 20v runs 11.0:1 from factory
