hmm, weird. yeah, check them out. Being that it is a 1j, they really dont take too long to get out. So much nicer then a 7m. How is the power?

Big update and hopefully the SC3 can try. I am not sure if you have changed your plugs yet, but i would definately suggest. I just did last week and one of them were basicly broken. It had been bent and had a gap of less then .12. That was what was causing my 11-12mpg and basicly no performance...

It is not mounted, the mount broke during engine install. It hasnt made any noises until now. I am going to deal with it soon.

That would explain the higher numbers

Damn that is hot! :) Also, to edit, it wasw 842RWHP

It was boosting fine, just noisy. I will double check later, but i didnt change the vacuum lines on the avcr when i was messing, only the map sensor for the engine and i didnt do anything, just disconnected it and reconnected it. I was trying to connect it closer to the throttle body opening...

Got it! OK, that is exactly what i was thinking. But no mount sadly, it got crushed when i installed the engine accidently. I just wanted to make sure the noise was normal, it sounded very weird. I really wonder why it started now. I have been running 14 lbs of boost since i started driving the...

Yeah, it has never made noise until after i fixed the engine. I havent had time to look at it in the day, but something went weird when i worked on it. It sounds like the noise is coming from the map sensor location. I will check it out today. But running without it isnt that bad. It boosts 10...

Update: Well, i was really freaking out about the noise. It seemed it was just coming on with boost. It sounded really funny, like a small motor under boost. It started making noise at 1lb of boost and went until i stopped boosting. Well, i got an idea and i turned off my AVC-R boost...

Umm ebay, they were definately the best price of anywhere.

Fixed. Yes, it barely was open at all. I didnt do it, it was in the engine when i got the 1jz.

Okay, so finally after driving this car for nearly 3 months, it has power and tons of boost! I was sooo confused why it never felt that powerful. I mean, i could get it to boost when i pushed it, but it felt like i was always fighting it. Well, i spent the night working on the supra. I have had...

Okay, i spent the night working on the supra. I think i might have fixed the problem. I have had the iridium plugs sitting around to be put in, so i finally did it. The rpm bump is totally gone! YAY!!! and the car has a freakish amount of power now!!! YES! So yeah, i just took it out and had a...

I am up in bellingham, i might be open to this. Do you already have a 1jz running?

You usually don't gap them, but if you want to, you just bend the arm and don't touch the electrode. I think you can go to sparkplugs.com or something like that for a good walkthrough on gapping properly.

I would say it is because one of the main issues with engines it getting hot air out asap. Having a larger exhaust valve would allow more air to flow out and reduce the chances of a cracked head when you are really pushing the engine hard.

Okay, so does anyone have any ideas?

Yup as i wrote in the original post, it is getting about 12.5 at startup and going just about 14.7 after warmup. It seems very consistent. By my a/f maps, i would think i was getting super amazing fuel millage, but it is the complete opposite. That is why i am so confused. If anything i am...
