Update ( 8/13/08 )

As some of you know, I headed up to the shop today upon the good news that the transmission was finally in and it was time to start working on fabrication of the turbo setup.

When I got there, Eric had already started trying to figure things out as to how to route everything. We had debated debated doing a driver's side Intake setup but for the sake of time and cost effectiveness, we decided that it wasn't too great of an idea at this time. I remember that I saw this picture a while back on 3si:

I was thinking of trying to route the charge pipe like that around the side so that the turbo would be between the intake pipe and the block but yea...it definitely is not going to work like that. There just isn't enough room. So we decided to push the turbo out to the left side, angle it so that it slants towards the passenger headlight and to allow the original piping to pretty much go back the way it was. Here's a pic of how the cool side piping was when I was TT:

We are pretty much going to keep the intake pipe where it is and route the charge from the turbo through the 2.5" IC piping in the front of the engine bay. Ofcourse we will move the battery permanently to the back and figure out something with the fuse box.

Finally here are the pics from today. The only thing we did was move the turbo about 6" back towards the read of the engine bay:

And here's my baby after we pushed her out for a few moments to get Kyle's car on the lift.

It's jacked up I know but it still brings a smile to my face haha. Now it's just time to install those intrax springs

I feel you my friend, I feel you...

Heh, ive got a much simpler setup that keeps the length of the piping down and allows you to keep your A/C, ps, cruise, and heater, you dont have to move the fuse box, and wont melt shifter cables!!!!!

Let me know if you want pics. Personally i think the turbo over the trans setups are just a cluster fuck and you get tons of heat just sitting under the hood there and heat soaking the charge piping that supposed to be cooled down from the IC, not to mention you running a downpipe for the over the trans setup is a PAIN and has TONS of bends and possibly notching the subframe.

Jeff, send me those pics cuz I would love to keep the piping short and still get away with keeping stuff as cool as possible.

I am so happy to see the progress. I'll post the maps today, I was dead tired when I got off last night.

Link to great discussion on Supra Forums:

T61 vs T67 - Supraforums.com

Some have considered the GT35r:

Honestly I hear great things about it from the Evo guys, but I think when I turbo my new car I'm going with a 40r myself

Maybe last year I could still understand the turbo over the trans idea... Maybe. Today though? There are SO many set-ups floating utilizing far superior turbo location.

Example Adam? I've only ever seen the turbo in these cars over the trans and in front of the engine.

Yea Jeff gave me the info I needed so it definitely looks like this project will take a slightly different direction.

Mike, thanks for all the info, I just hope that I made a wise choice with the Master Power T70. We'll see how it performs and at the very least this will be a thread on what turbo not to get hahaha. I think it will do well. I'm going to make sure that its performance is well documented here.

Well, those that have ordered and run the MPT70 on other forums seem happy with it. There are a few N/A-T guys running them, browse Club NA-T and have a look. I don't think it will be a bad turbo for our platform, I think you'll be very pleased. The consensus on this turbo from the 2jz crowd seems to be that she's slow spooling (relative to the 61/67) but has massive potential for making good/high hp. 500hp shouldn't be a problem here bro...others have already done it with less mods (albeit a different engine configuration).
