You could've easily found most your answers through searching. That's why you haven't received any response. I have nothing to do so I'll answer some: Get an safc. It'll allow you to boost higher. I personally was boosting around 19psi. Stage 1 cams? Never heard of it, but if you do small core...

oh, so it does run and stay on it's just when you throttle it? or does it not matter and it dies out eventually? When it does run, does it sound healthy like its firing on all 6?

pull the coil plugs one by one...if when you pull one and it stops missing or nothing happens then you found your culprit. What I would do next if say...cylinder number 4...you pulled the coil plug and it stopped backfiring, I would jump a wire from the igniter straight to the plug. Just find...

Having excess vac lines are common when you get the engine. I can't tell where 2 is coming from...if from nothing I would just cap off 2 and 3 for now...either with actual vac caps or jam a small bolt through the lines. Recent 1j i worked on we capped off a few lines. I'm sure someone will...

Check your fuel pressure or at least to make sure you are getting fuel to the injectors? Will it stay running if you keep your feet on the throttle?

that's a beast of a motor, but honestly i think it is only worth it if you'll be going FI in the future. the crown 1fz mentioned is insane!

From experience, one 1jz I had was installed with a large 100 amp inline fuse to the fuse box. It blew and had the same symptoms.

So working on a friends 1jz. Everything stock. First issue is no power to coil number 6 only. My main question is, is there anything in between the wires from the igniter to the coils or is it just straight wiring? I was thinking of checking continuity from igniter plug to coil and seeing if...

I'm curious if other half moon's would work on the 1j like from a 5sfe. I seriously would walk in to a dealership (the shop part) and ask the techs if they had some laying around. give them a few bucks for it. When I was at the dealer the techs kept a lot of spare parts like that. A little fipg...

Hi, No sir. You do not have to rotate the whole engine or put the t-belt back on. Just make sure you tighten the cam caps properly and put the cam bolt back in. Put a socket to that bolt and turn the cam. These are non interference engines so you're safe. sorry for the confusion. even the 272...

why don't you have the charcoal canister? I've always read that you should have that.

Thank you sir. I didn't want to assume that, but figure it would be considering it was the top wire out of the triangle plug.

can't believe no one has mentioned getting cams. this is just my opinion, but i was more happy getting cams then going single. food for thought

So the 1jz i'm messing with has 1 blue and 2 black wires for the oxygen sensor, no connector. The colors for the o2 sensor connector (wiring harness side) has a red, white, and black wire. Which wire goes where? I'm sure the two black wires can interchange, more concern where the blue one...

Hi, helping a person finish up his project. the engine is installed and running, but still need to identify the o2 sensor plug. is it this one? http://imgs.inkfrog.com/pix/tpmsexpress/possible_o2_plug.jpg?i=1362769292238 The o2 sensor we're working on right now looks like this...so we...

No offense, but get that shit out of here. First we don't have chain, rockers, push rods, or lifters. Secondly the manifold does not have to be removed. third, you should just delete your post.

19psi daily and in high altitude. SAFC, 440cc, mk4 pump, 272 BC cams, about 11.5-11.9 at WOT...I must say that I could feel a lot of power being restricted with the safc, but it did fine and I could beat on it all day with no issues...also drove from WA to CO like that. Made 368rwhp at 15psi.

I know for sure it'll still start if the o2 isn't hooked up. working on a 1j right now and we test started it without it hooked up. I too think you should check at least the "connection" to the cam sensors. A lot of times it isn't the component that is bad, but the wirings.

Still have the dp and y pipe?

fuel cut shouldn't have made him consistently lose fuel like that
