What I found & bought in a junkyard!

[cloudasc]

They finally were able to get the parts from the junkyard, and here is everything I picked up. R.I.P. (Rest in pieces) 92 auto ex @ 145k!

Here is the Front Valance/Lip:


Here is the oil cooler:


Here is the cam:


Here is the a6 head and manifold (front view):


a6 throttlebody & upper intake manifold:

a6 head & intake (ds view) Notice the air tank and iab sylenoid:


Bottom of head, cylinders 4, 3, 2, 1:

Here is the pt6 ecu:


Here is the tcu, which I won't be needing since I want to keep my "sport" mode:


Now I just need to aquire the throttle body and upper intake manifold from an h23a1. Found a junkyard that has it, just gotta pay for it, and pick it up.

By the time I am done with this project, I will have a complete a1 manifold & throttle body, upper half of an a6 manifold and throttle body minus the iab plate, and possibly the lower half of an h23 manifold. Heres to a G22.5 (f22/h23) intake!

nice so if you eliminate the butterfly deck you wont need to use the vacuum and all that ant it would install just like a a4 or a1 manifold but increase the hp/tq????

Your top end would increase due to the removal of the butterflys more air will flow, but your low end would suffer. The a1/a4 only has 4 ports from the plenum to the head, the a6 has 8, 4 open at all times, the other 4 open around 4k i believe.

thanks for the info ... i value my low end more than top ... i want to increase low end tq not top end hp...

That is why I plan on retaining the normal functioning of the iab system, but I plan on throwing on a h23 upper manifold & throttle body on the a6 lower manifold & iab plate. That will keep the low end, and also help the top end. My plan for the best of both worlds.

Can the oil cooler off the ex work for lx model cb's?

I have a 1990.

Yes, I have a 91 lx, and I'll be putting it on when I fix my oil pan gasket and will also be installing the a6 windage tray which I am currently waiting to arrive from majestic honda. The oil cooler is only found on a6 motors. So a 90/91 ex will not have the oil cooler, only the 90/91 se. 92 EX & 93 EX/SE have the oil cooler.
