i have an intake for sale, no longer needed as the itb project went well.  i have no idea what the original application was, but it worked perfectly in my 85 si.  the filter rested on the passenger wheel arch, and i had no problems despite it not being securely mounted.  the pipe has a 2.5" od, and both clamps on the pipe are turbo type t bolt clamps.  i did not have the proper sized clamp for the throttle body, but the worm drive clamp on that side never gave me any issues.  the silicone reducer fits nice and snug to the throttle body, and although the filter is still usable, it would probably need replacing sometime in the near future.  you will have to get a little creative if you have a stock battery, but the lithium battery i used also dropped almost all of the weight of the lead acid battery.  

i am no longer going to need this intake, and i would like to know that it is going to be used rather than sit in storage forever.  i have no idea what it is worth, so please feel free to make a reasonable offer.  i am not looking to get rich selling a used intake, i just want to make it worth my time.

edit, all sold-

hello peppers, i am putting up for sale a bunch of twin cam rebuild parts that i received with a car i purchased a while ago.  it seems like just about everything needed to rebuild an a1/zc? i am not going to use them so i figured if someone would offer a decent amount i would rather have them go to someone that would use them.  otherwise, the parts would sit in storage forever.  

parts included are:

main bearings (king) 13321-pg6-003

rod bearings (king)  cr4046am

oil pump (agm?) t-oph21

top, bottom, and oil rings (hastings) 2c4640

thrust washers (acl) 1t1957-std

timing belt (overseas import corp) ha 14400 pg6 004

water pump (gmb) 19200-pg6-000-j

timing belt tensioner (cym auto parts) 14510-pg6-013

thermostat (gates) 33568

spark plugs (ngk) r5671a-8 these are fairly cold and gapped very tight so probably for a boosted application

oil filter (filtech/honda) 15400-plm-a01

aside from a set of gaskets and some machine work, there are not a lot of other parts i would replace in a complete overhaul of an engine.  i would like to sell all the parts as a set, and although i am not giving them away i am not expecting a lot as well.  please pm me if you are interested, i should be able to get everything into a usps priority flat rate box so shipping should be about 20 bucks depending.  pictures can be seen below-

now that it is finished, i figured it would be nice to share my experience getting a set of itbs running properly.  i know that there are not very many people that want to fight the ever so steep uphill battle with the ew engine with swaps being fairly easy and instantly gratifying.  i like my stock engine, and have spend enough time and money on it that going for a swap was not really high on the list.  going with the road less traveled and surprising fellow auto enthusiasts/ autocross competitors with a 30 year old engine holding its own is much more fun to me.  i had to make a push during our off season, and by taking my time and gathering everything needed before starting on the car itself, things proceeded smoothly and all unknown variables did not prove to be show stoppers-

this was the car as it started, definitely not a show car but perfect for its intended autocrossing duties:

sousa speed kindly gave me a good deal on an initial buy of his distributor adapter plate

a new obd1 distributor was acquired for really cheap on ebay, and then a rywire harness was sourced for integration of the engine to a newer obd1 ecu and hondata s300:

and lastly, a set of used itbs from a cbr954rr:

these were selected mostly because the tps is standard honda.  as it turns out, the outer wires on the plug have to be swapped, but it is definitely the easiest way to get a proper tps signal to the ecu.  

injectors turned out to be around 240-260cc and use an injector dynamics 2000cc plug, so the stock 954 ones stayed put with the aid of injector adapters sourced from rywire.  if the oem harness is included with the itbs (as pictured), it would be easy and much cheaper to just splice them in to whatever harness was being used.  the throttle cable cam will work with the crx throttle cable, although the mount on the itbs will have to be slightly enlarged to hold the throttle cable and the cable itself had to be shortened.  that was no problem, and i used an aluminum ferrule as a new stop a few inches up from the end of the cable.

the only thing that had to be farmed out was the runners for the stock manifold.  i used a stock lower half that was cut and had a set of aluminum pipes welded on.  the pipes were readily available on ebay as radiator hose extensions, and came with rolled ends as a bonus-

spacing on the middle two runners was just about perfect, but the outer two were slightly further apart (about 10mm more if i remember correctly).  as the stock 954 rubber boots were angled, i was able to spin them outwards and get everything to line up well enough.  it goes without saying that everything should be set on the itb side before the pipes are tacked onto the oem flange.  my welder was also kind enough to seal up the original injector bosses-  flow is not optimal of course with the void inside the manifold, but i was willing to accept whatever negative issues came of it.  

having situated the most daunting portion of the project, i was able to estimate that the fuel line fittings would work from both vehicles, and vacuum would also not be much of an issue with a cheap block to feed the booster.  the stacks from the 954 fit perfectly (of course), but a set from a 04-05 cbr1000rr also worked and were both shorter and more symmetrical.  airbox design was apparently drastically different and i went with the shorter stacks for a tidier appearance and zero chance of interference with the booster under heavy engine movement.  any high rpm power gains or low rpm losses were not really considered with the stack choices; i do plan on trying the longer set later if i get curious enough.

having an obd1 ecu required a speed signal, so an hf speedo was swapped and wired as it has been done so many times before.  i cant say there is a more elegant solution especially since the clusters are getting harder to find, but luckily i was able to find the required pieces and when i got the car on the road for the first time, the speed signal was pretty much spot on with the cluster.

installation of the harness was fairly straightforward, with a bit of wiring needed, and once the proper orientation of the distributor key adapter/extension was determined, it too fell in line quite nicely.  the 954 cold start thermo setup was left in place and plumbed, and it helps quite a bit with warm ups and initial driveability.
