Idlefree,

Would love to see some more detailed pics of what they had to do to the tunnel to clear the tranny. Also what your doing in the car for shifter.

Thanks,

Shane

Hey Shane,
The tranny needs to come out one more time

That TCI Outlaw shifter is a beauty . I was reading ATF's build on your tranny and damn , a lot of money on that trans setup man . The 2.10 gearset alone is almost $2k .

All that trans setup at $12k is not a joke but it will be ready for whatever power / torque you will build your engine.

You are indeed going for it ... congrats and good luck !

Love the build; so, please don't get me wrong. I'm simply offering up my experience with one-piece drive shafts. Hopefully, you'll have better luck than me.

I've had two one-piece DSs. One was completely dorked up by one of the most reputable, nationally-known shops. It basically shook like a vibrating bed at a cheap Motel. The other driveshaft came out pretty well and was done by a small shop that specializes in high HP drag cars. I even had them use the OEM U-joints at the tranny output shaft and differential. But it still doesn't compare to a re-tubed two-piece DS. There is no vibration, and it's handled 1.4x s launches on a six speed at over 850 whp. And my car weighs 3850lbs with me in it. Consequently, I have no concern about the Toyota made spline joint in the middle of the shaft giving out. FWIW, the small shop that fabbed the one-piece DS re-tubed a MKIV two piece and lengthened it for the SC.

Just my $0.02; so, please don't be offended.

Keep us posted on your progress!

Thanks,
-scott

Thank you Gerrb, my goal would be around 1500whp by next racing season
Your builds give me hope, that it can be done and as always thanks for your time and help through P.M.

Thank you Scott,
You are 100% right my machanic warded me about that and said thier will be a chance it happens. He did say I may have to go with a two piece.
The machanic has built a MKIV with a 4L80E pushing 1200whp on a single axle and so far no issues, but it does rattle a bit.

I do appreciate you advise, it helps a lot when people give thier input or past experiences.

I will update as things go.
Cheers and thanks for the support

Hey Shane here is some picture of the tunnel after it has been massaged to fit the 4L80E
Johnny from Toronto Auto Repair did a great job, to make it not over banged in. It was just enough to fit the tranny.

Thank you 8052JZ,
Yes lots of hammering, Johnny from Toronto Automotive Repair has done an amazing job on the tunnel, he use wood to make sure the metal wasn't damaged or look badly beaten up.

Yes it is a ATI 2JZ bellhousing from AFT speed transmission.

I will be going with 3.769 from a Toyota Supra TT with LSD rear end TRD

Cheers

Awesome! I just finished my th400 swap as well but I used the jz bell housing. I didn't feel comfortable mashing up the body for the 4l80 to fit so I went with the th400. I had to hammer out one small area for the shifter lever. But great work!
