where can I find any info???????, jdm 7afe head Options

[dans_st]

I recently bought a JDM 7afe head and I am planning on swapping onto my 7af(t)e, I just cannot find any info on what to do since the JDM 7AFE does not have a distributor, I have tried searchin, and all I find is "JDM 3SGTE" stuff.
I would like any information I can get, I am not too concerned with the loss of EGR as my car is not using it right now anyways I just have a resistor on it and it seem fine.
I have also heard that I can use a ford EDIS system, what do I have to do to do this, I do not want to got over to a standalone, I currently am just running stock ECU with SAFC-II and plan to either looking into PROM tuning or if I cannot do that possibly go to E-manage ultimate.

Also is has anyone ever looked into siamesing the intake/head ports on intake side, I have done this on my 350 TPI Camaro, and it has really raised my powerband and output and the runners are very similar.I lost some torque output but am willing to do so to gain some higher RPM HP.

this is part of a long term project just I am trying to get as much info as I can.
thanks for your help

erm.. guy's, 1 thing i dun really understand.

"However, the combustion chamber will need a lot of work to make it produce a lot of power. I've looked at a lot of different types of engines and found certain consistancies with squish areas that I will be using when finishing the chamber. I'll also be trying some Formula One style tricks with the chamber. This means a complicated piston top shape, and hopefully I can get exactly what I want made. The exhaust ports will also need a lot of work, but fortunately the work that needs to be done makes them end up all the same gives them a very efficient shape. The other reason I want to use this head is because they use 31mm diameter cam buckets, rather than the smaller 28mm ones that the 16 valve 4AGE's use, and somewhat larger than the 23mm ones the 20v heads use, so I can run a cam with quite a lot of duration & lift without having the lobes run off the sides of the buckets. I have found a standard 31mm Toyota bucket that uses no shims at all (it has a small 'stem' underneath that is trimmed to the right length to get the right valve clearance) and so is very light indeed."


is he reffering to 7AFE head having standard 31mm diameter cam bucket? Or which F head he got himself there as per describe?
