I would try to get a lil bit of a refund for the f-ed up harness and get an SDS from the first. You will thank yourself.

that goes nowhere, someone Teed into that hose for a boost gauge.

the metal pipe is a vent, it goes to nothing. The hose I believe carries water from that manifold gallery back into the main coolant hoses. You can probably cap that.

The thing has obviously been modded a little, especially with the cut up harness/boost controller/Silicone tubing....the cam covers have obviously been off also, I'd check compression in that thing, maybe even pop off the cam covers and see if you have stock cams or who knows what.

I doubt an engine with a stock BOV has highcams in it. Can't hurt to check though.

the hose off the wastegate was problly for a boost controller.... just get a motec ems or something like that... make it alot easier to wire up ... plus then you would have a standalone to tune with.... and i agree with mad pull the valve cover and check whag is in there...might be a nice suprice to boot

the plug near the TPS thats not there is for auto. dont worry about it. the hanging plug below it is the tps plug.

the vaccum line off the wastegate was cut cause it probably went to a boost seleniod. it needs to go to a vaccum source, perferably off the intake manifold. thatll give the lowest stock setting on that wastegate actuator

edit: the cut part id guess to say avcr. it looks pretty hacked up because it was probably modified. you might get lucky and find some cams or something!

well first of all that is one clean motor. with i got mine like that

your lower harness you got with the set well your not going to need that.You use your KA harness becuase you are swaping trans switchs and everything will plug into the rb from the ka.

As for the wires cut near the ecu. The blue relays are removed when you rewire the harness becuase you car has the relays in a box near the battery. For the cut wires after the gromet(sp?) one is for the MAF (you have to cut this to length the MAF anyways) and your MAF should have the plug on it.I can't tell from the pic but the other wires near the MAF is O2 sensor and that has to be cut as well.it need to be lengthen so it will reach the O2 becuase it is on the other side of the car now.

oh yeah and that long tube comming out the intake on the back of the motor I think that is a water line. If it is a water line then it should feed the turbo. IIRC it T-ed of it. I can't remeber if it was a rubber or hard line.

yeah it looks like like it is puking oil out the compressor wheel or the motor never had a catch can. hopefully the later.

it still looks like the stock t28 just has a cleaned up housing.

okay good... got a little worried about that plug near the tps.

and yeah i was thinking the avcr or a safc or something for the cut up wiring. ill have to start pulling stuff to see what i actually got

i know you use the ka harness with the rb plugs, but i want to know where those cut wires on the rb lower harness go to.

which ones are you talking about? on my maf plug there are red/grey, white, and black wires coming from it. and they are thicker than normal.

thanks a lot for the input everyone.

the turbo seems fine, that black crap on the inside there near the compressor wheel is just dirt or whatever, its definitely not oil.

The one wire on your lower harness that looks like a wire that had the tabs pulled out of a plug? (sorry dont have time to circle on a pic right now) but I have the same thing I think I pulled the wires out of the plug when i pulled the motor from the clip so I need to look on my clips firewall. Any ideas to what that is anyone?

Actually here is a pic of mine to compare

I don't really see anything to be PO'ed about. You got a motor. Unlike about a dozen people from knight seven or UH. They let you have the goodies with it. 90% of the cut harness stuff needs to be moded anyways.

What was the price of this motor set anyways?
