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

What do you mean the JDM 7AFE doesn't have a distributor? Does it have coil over plugs, coilpacks, etc? You can hook up your USDM distributor and it should work so long as you use the stock ECU and the exhaust cam has the slot for the dizzy (which it should). Just because it's a "JDM 7AFE" doesn't make it any better than a USDM one. If you want to go DLI, then you'll need an aftermarket standalone ecu. No ifs ands or buts. The ford EDIS "mod" so to speak is typically used in conjunction with Megasquirt, a standalone ecu system. There is no practical way to "chip" the stock ECU to run DLI. Personally... I think the non-TVIS 7AFE head is far superior to the TVIS 7AFE head based on the intake port designs alone.

As for the intake manifold... if you're reffering to TVIS... here's some info for you. TVIS is NOT a horsepower design. It is a designed based on restriction and intake velocity to make torque below 4000rpms or so... IMO, it's completely useless depending on the type of turbo you're running. FYI, most 3SGTE guys when they go with bigger turbos and more efficient set-ups... they get rid of TVIS because it's a restriction under low throttle and rpms.
