    I pretty sure you won't get much more hp but the torque is great. But I think mat(pen15) car made close to 90kw on the 4age bottom end. And also when doing the said 1zz crank it tips it over a 2l.

    if you do end up doing it, remember that the key part to the 7ac is a Mitsubishi colt timing belt

    I have a question aswell, im just gathering parts for 7agte setup, using a blacktop head, i already have a brand new 7A oil pump, will this be sufficient compared to say, a blacktop oil pump?
    what differences are there, just volume?

    any help would be great

    the thread is building a 7age but you get an A+ for effort i cant imagine why you would build a 7ac unless you had a magneto coil and mechanical injection but still a very cool engine what timing belt/chain did you use and things
    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

    Okay mine is kinda basic, not quite as crazy as delazy's monster. Should be fun though!

    block - 7afe stock
    crank - 7afe stock
    crank timing gear/sprocket - bazda modified (offset keyway)
    flywheel - J-Works 4kg chromoly flywheel
    bearings - kings
    conrods - J-Works H-Beam
    pistons - ae111 4age stock
    oil pump - 4age 16V + 4age 16V tensioner
    headgasket - stock ae111
    head - ae111 20v slightly ported
    cams - TODA-R 264, 9mm
    cam gears - ae111 4age stock
    timing belt - 4age 16v stock
    intake - ae111 itbs/70mm J-Wworks stacks
    extractors - RSR, soon to have J-Works 'Octopus' headers
    cooling system - Garage Annex
    ecu - ae111 4age stock, with Garage Annex modifications (unknown. could just be speed de-limiter)
    fueling- ae111 4age stock, TOM's or stock ae111 4age FPR depending on what the wideband says
    miscellaneous - ARP head studs and ARP bolts

    I hope to make 120-130rwhp. My <2" exhaust from headers to cat will be quite restrictive though.

    on my boss's 20v stroker 7a he uses a stock 20v timing gear on the crank and then uses a Peugeot timing belt how come you guys dont do the same?

    does he use cam gears? if he is using adjustable cam gears and disabling vvt then he can dial the timing differences out with those, but if he is using the vvt timing pulley, then the simplest way to reset the timing to the correct place is to recut the timing keyway...
