Well i’m building a 91 RS Withh full forged internals, turbo kit etc…
Anyway i have the engine out and i have a few questions as this is my first time rebuilding a honda
Thanks in advance for the advice.
What in the world is this, i found it on the ground after pulling the engine and it looks important
What is this soft-feeling box on the rear of the engine? i busted that little tab going to the intake manifold by accident while removing the intake
There are these 2 plugs on the rear of the engine that are holding me up from removing the wiring harness and essentially building my engine, what are they/what do they do, and how can they be removed?
(sorry about the photo size, doesn’t seem to want to resize on photobucket)
Thanks, Ranin.
the first pic no clue i cant really tell thou. the 2 pic is ur pvc breather box aka black box. r u running a catch can set up? if u r this will get eliminated ( recommended) on a honda/acura boosted motor. search catch can set ups.
^is it the end that goes into the cluster? If it is, usually it can be repaired. If it can’t they are pretty inexpensive…about $35-$40 from the dealer. Good luck!
Can you provide us some specs on the build? What are your plans?

Its not broken it just fell out. it goes right in between where you screw the cap onto the trans side of the speed sensor line.
As for the build, full rotating assembly with 8.5:1 compression, stock flywheel.
not doing much with the head, stock is already good for boost, maybe a minor port and polish, with stainless steel valves, new springs and retainers, stock cams.
for fuelling ill have a 255 walbro with 450 dsm injectors and a fuel pressure regulator
as for turbo, ill get a kit from ebay, log-style header. swap out the turbo for something better.
some people dislike the ebay kits but in reality 95% of the stuff is fair quality and pre fitted if you know what you’re doing. Msd digital 6 plus, along with a wideband and fpr you can pretty much tune it yourself.
My plans arent set in stone but this is the basic idea so far.
my last build was an ls/vtec swapped into a 89 civic. 300hp with a 65 shot of nos.
13.4 quarter mile.
1st pic - speed sensor cable cover that goes on the transmission housing
2nd pic - breather box a.k.a. black box
3rd pic - smaller plug, oil pressure sensor 1/8" BSPT, this is where I tee’d my oil pressure gauge. Bigger plug is the coolant temperature sensor, you will need a 22mm wrench to remove the nut. You can unplug both by removing the rubber jacket that goes on top of them

yep i ended getting the wiring off without breaking anything haha.
What would be the proper way to eliminate the blackbox with a catch can?
i was thinking the hose from the intake manifold would have to run to one connector to the catch can,
plug the big hole in the side of the block (with what?) then would the other hose go to the connector on the valve cover?
