    Jason, can you post up your NA curve?

    The above graph of the same motor as the turbo setup less the folowing details:
    Full early AE86 JDM ECU/electrics.
    Exh cam was 240deg bigport, had cam wheels probably set 116/114 or so.
    Stewart Wilkins racing 4-2-1 extractors, 2 1/4 press bend exh, cat coverter, 2 Noby Booth mufflers (if you can call them that).

    Resonable numbers, peaky as per any NA motor. A/F was lean but motor never detonated.

    Oh, I run only Premium in my cars.

    Last week I had a good conversation with one of the fuel engineers from BP, discussed high octane fuels etc at length, quite interesting.

    jaz ae86: in your turbo setup engine, boost appears to be 12psi from what i can see? What was your reasoning behind this, could you bump it up a bit more?

    I want to lower the boost - am going to be trying S15 0.64 exh housing (which has small wastegate seperator in it) to stop boost creep and come on boost sooner.

    The result on a contant 12PSI would be more than 160rwkw, which frankly is WAY to much for a bigport motor to handle. We are talking 192kw at the crank on a motor they say is at it limit around 200hp at the crank. At max power there is about 9PSi showing on the graph

    The other thing of note and food for thought for everyone: I am running the 'bigger' exh housing for the S14/S15 ball bearing turbo at .86 (off JDM S14 auto) yet I have overboost issues. Excluding that the factory pump pipe on the Nissan is better than my 3" mandrel dump, do we assume my little 1600 flows more air than an SR?
    What it does tell me is that I was correct in choosing 264's for my turbo motor.

    hmmm very interesting

    anything to do with exhaust gas speed leaving the head? maybe 4age has better exhaust port flow than sr20....although the cam would help with this alot i would imagine.

    so by running the .64 housing instead you will be sort of limiting the exhaust gas that hits the exhaust wheel at once? i mean with the .86 housing, it allows more gas in the same area due to the larger housing?

    im not exactly upto date with housing sizes and outcomes....i know a bit....but yeah....

    Frak, I converted peak BT KW to HP, then multiplied by 1.17 (17% drive train loss)...which left me with 149hp at the flywheel.

    The ST is supposed to have 160, BT 165~170hp. Is there something wrong with my conversion, or is your dyno pessimistic? Toyota's claims optimistic?

    The curves of your BT vs the ST, is that typical? I'm surprised the ST ran out of breath so quickly. I did not know it was that severe. I'm kinda of glad I paid the extra $350 USD for the blacktop....

    Also, the torque dip...is that also typical of a BT? Sorry for the questions, it's rare for me to come across good info like this..
