Default Integra GS-R B18C1 engine part out

I'm parting out my 1996 GS-R B18C1 engine to make way for a rebuilt JDM ITR swap. I'll be posting parts throughout the summer as they come off the car and I get my ducks in a row. All parts are in working condition as described. Please feel free to PM with offers on TBD parts but be aware that if they are listed here they are still on the car and some items may still be a few weeks/months out. I'm recovering from a broken jaw and it's slowing things down. If you want to see these parts in situ see my build thread! I need these parts out of the garage and I also need to recoup some costs of the swap.

All prices are OBO (shipping from Montana included in price). We can make a deal if local pickup is possible. Be advised shipping is VERY expensive these days especially from Montana. I'm doing my best to keep prices down but no low ***** please.

All parts are B18C1/p72 unless otherwise indicated. Buyer must confirm fitment. Please feel free to PM or ask questions in this thread.

The engine has ~150k and is from a 1996. It needs new seals at the very least. All seals, guides, rings, etc. are ORIGINAL. I can sell it as a long block but was planning to part out. If you are interested in buying it as a long block or full part out I am flexible if I have a serious buyer. I have to remove my Blox A cams from the head but can sell it bare or with '96 JDM ITR cams installed on ITR springs.

Mods I will add prices to this list as parts become available with photos.

AEM V1 CAI: Red 21-404. Some surface scuffing. See listing below. $180
OEM GSR Throttle Body: Includes TPS sensor and throttle cable bracket. $180
OEM GSR Throttle Cable: TBD
OEM GSR Intake Manifold:
bare TBD
OEM GSR Injectors: TBD

B18C1 Bare Head: TBD
B18C1 GSR Exhaust Cam: TBD
B18C5 JDM ITR Camshafts:
Intake and exhaust. 1996 spec. TBD
B18C5 JDM ITR Valvesprings: TBD

B18C1 Short Block: TBD

OEM GSR Exhaust Manifold:
Cast iron USDM TBD

Misc. Parts: TBD

AEM CAI V1 Red for B18C1/GSR. See CARB sticker. Part works fine and the tubing is 100% sound but it has some blemishes where it was near the frame rail and where it passed into the under-car area. Most or all of these blemishes are invisible once installed, but be aware of the bent bracket. This does not affect performance. It might be possible to heat and bend this back but I did not want to risk breaking it. This should fit any 94-01 Integra with a p72 GSR OEM or compatible intake manifold. I don't know about fitment in Civic swaps.

$180 shipped OBO (keep in mind shipping is nearly $100).

OEM Throttle Body. Includes TPS sensor and throttle cable mounting bracket. This is compatible with any GS-R/p72/B18C1 setup. It will not be compatible with LS/GS/RS/TypeR intake throttle cables. This is original unmodified equipment. It worked perfectly on the car--no sticking. I am replacing it because I am swapping in a B18C5.

$120 shipped OBO.

How are the engine mounts? Would be interested in the 2 front mounts: the block and transmission.

96_Piecer: I will be using the mounts for the B18C5 swap, but I might have some others in my misc parts bins. I'll have a look and post photos. Everything is in pretty good condition--this car has never been treated rough.

GreatWave: The head is off, available, and ready to ship. I just have a single valve keeper hiding somewhere behind the IM . It went on an adventure. I can find it for you if you don't have spares. I have three camshafts available for sale: JDM ITR intake, JDM ITR exhaust, and USDM GSR exhaust. Would you be interested in the head with or w/o cams?

Sure let me know if you have some mounts lying around. Looking for OEM as the aftermarket ones i bought are just way to stiff to actually enjoy driving currently.

Engine block and ECU are sold but the head is still available. Asking:

OE JDM ITR Cams (96 spec) -- $500 OBO
OE ITR Valvesprings -- $150 OBO
OE USDM GS-R Head -- $700 OBO
OE USDM GS-R IM -- Make offer


The head is complete now but I can part it out or sell as a unit. Estimate $200 for shipping the head to USA addresses.

Do you have ITR valves (along with the ITR valve springs) or GSR valves installed in the P72 head ?

It's the original GS-R valves in the GS-R head. Only the valve springs and cams are OEM ITR. I have a newly rebuilt ITR head I swapped my cams and valvesprings into, hence why this head is kind of a frankenstein. The valves could use some cleaning and the guides and LMAs are original from 1996 GS-R so I'd recommend buyers consider replacing them anyways.
