No the igniter isn't interchangeable.

I just don't like the thought of a CT26 on my 1J. That's why I went 1J. So I could get away from that hellacious 7M. I hated that thing! I don't want anything to do with that motor ever again (unless i get paid). This was me... ::bhg:: ::bhg:: Yes, twice! The 7M can burn in HELL! Along with...

I'm curious as to what that set up would do. Has anyone done that? Someone go buy a 1J and a 2J, then swap the heads with each other and put them each on an engine dyno. What would the results be I wonder? Any opinions?

He may as well do so. He answers everyone elses questions. Why not his own? :biglaugh: Plus he said he already knew the answer... he just wanted it confirmed. So, I agree. It's because you had the thing tuned with the with the leak. So get the thing re-tuned with no leak.

I've always thought of it as a known fact that the 1J head flows better then the 2J head (stock) and that's why people do 1.5's. I've heard that from severat people. Even 2J guys with high horsepower have told me that. I always thought 1.5 was the best way to go. That's from word of mouth...

It's not that hard. Even for someone with not much experience. Just remember how you took things off and where things go. It's doable in a driveway but don't park behind anyone in case you run into some issues and get agrivated. :biglaugh: Don't want to block anybody in overnight.:biglaugh:

I can't remember what numbers i got when I compression tested last. As long as the numbers are all around the same, you should be fine.

Well I'd do a compression test to rule out any head issues just to be safe.

Wikipedia knows ALL!!!!! :bowdown:

That's not good. It doesn't sound like a turbo issue. Sounds to me like you might want to do a compression test. White smoke is usually coolant.

Ok, got it. Anyone know how much torque the R154 can take? You guys think it will be able to hold say... 650, 700, 750 tq?

I think the bolt pattern for the 7m is 6 and the one for the 1j and 2j is 8.

Yes it includes a flywheel.

Won't a 1j clutch bolt up to it?

Ok well Supracharged88 is saying the bell housings are the same size and AZN MK3 is saying they are different sizes. So are they the same size or different sizes? I understand what your saying AZN MK3... I'm not a moron, but Supracharged88 says the housings are the same size and said, "Any M7...

They do all work the same but the 7m intercooler has both the inlet and exit on the same side. The one for the 1j has the inlet and exit on opposit sides. If you were to use the 7m intercooler, then you would have to do some extensive plumbing to get it to fit. If you look at how the 7M is set...

If you find out that your turbos are bad, I have a set of stock twins up for sale. They worked just fine when I took them off to go single. However there is one thing wrong with them. The front turbo needs a new inlet housing (you have on your car right now). It broke when I crashed my first...

Well I'm glad I have an R154! So as it stands, the R154 is much better. Cool. I feel enlightened.

What kind of set-up do you have?

Then why did I find this quote on MVP Motorsports that this clutch will fit the 1J tranny but not the 7M tranny? Are they just wrong? "This is made to fit a 1JZ-GTE motor and a 1JZ-GTE transmission. It does not fit the 7M-GTE R154 Supra transmission. Picture here is of a Twin Disc for the...
