It's not finished just yet, but I couldn't wait any longer to post. Been busy the last couple days!

Started out by pulling the trans... this is a pretty long winded process. Some aspects were easier than I expected (TC bolts and bell housing bolts), and some things were harder than I expected. My 06 doesn't have a nut on the alternator, but I was able to turn it over with a screw driver on the flywheel teeth. First day I pulled the trans, pull the up-pipes, did a little work to them, wrapped them etc. Stuck my new DPC single converter on the Allison. It didn't want to seat all the way, finally figured out the splines were a bit to tight to do by hand, had to tap it with a block of wood :eek:

Day two I pulled the stock turbo off. Not terrible with the trans out, didn't remove the egr delete pipe, bridge etc. left glow plug controller and all that in. Wow the valley is deeper than I figured! Started the new sideways turbo build. (Thanks to Trent at EPR for a fair price on the 366 :hug: ) Built an oil drain flange and pipe to hook a drain line to. I bought some stainless pipes, flanges etc. to work from. Just kind of winged it on turbo placement, and I think it's going to work great!... the hood even shuts :rofl:

Tacked it together and started welding things up...

Day three (today) Finished building the up-pipe2 setup. Made some braces to help support the turbo. Wrapped the setup and installed it, then installed the turbo, drain line etc. Made a feed line utilizing the factory banjo fitting. Made up a hydraulic hose to finish that up. Built the intake, also modified the hot pipe to get that done, put in provisions for my water/meth and boost gauge etc. That pipe came out pretty nice.. was worried it would look cobled but it looks good. Setup is pretty well done other than the exhaust. Tomorrow I think I'll stuff the trans back in so I know exactly where the motor will be sitting before I start on the hood stack :D

Thanks for looking guys... been wanting to build this for a while now. Every once and a while I gotta take on a big project and really get my hands dirty :)

I'll keep updating the thread, plan is to have it running and start tuning it friday... saturday at the latest if I run into snags.. Not going for big power, still stock clutches w/ a co-pilot. Going for decent HP at a high rpm to keep the torque from getting too high.

thanks,

Todd

Looks good. How much clearance under the hood, or do you have to buy a cowl hood now?

Thanks!

I love everything except for the 90 coming off the turbo. it just screams blown boot to me lol. but great job and love that you did something different..

Thanks, I hope it doesn't... that area ended up a little tighter than I had it visioned in my head. I probably won't see real big boost though so that may help lol

Thanks, It closes lol... from what I could tell, I had around a 1/2" or less....cutting it pretty close

put a dodge 90 housing on it maybe
Click to expand...

That's a good point, they do make a 90 housing for the 66 iirc.

That looks great man! notice any advantages to it?

Hoping to have it finished up Friday! Excited to see what it's like!

can you maybe clock the compressor cover so that the IC pipe comes over the front and then down?

I was wondering the same thing. But then that pipe would have 3 90s in it.
Just wondering why you did it backwards from Trents design?
Click to expand...

That's a good point. I did see someone who had done it that way. The thought did cross my mind today. I had already built a 3" IC pipe that just need a little modifying to work with this. Only thing I can say, is that where the turbo is, it might cause the compressor to be pointing up at kind of a weird angle if I went this route. Probably wouldn't be worse flow wise, but not sure it would be better? Would have been more custom though:thumb:

Looks good Todd!! Interesting pedestal design...cool.

Although I have to ask...why the sideways mount? I mean its cool to do things in a unique way, but is there a functional advantage? (im not being sarcastic, im genuinely curious)

As for the alternator, pop the plastic cap off, and theres a nut underneath that you can put a torx socket in...then you can turn it over with a ratchet just the same as if there was a nut there like on the older alternators. ;)

Thanks Ben!!! I don't think I have a torex that big lol! I went sideways to keep the up-pipe/pedestal design simple, pipes make one bend and enter flange... I think I could build a regular styled pedestal without too much more trouble, but this was more of a guarantee I guess.
Also, it made the Exhaust very short and simple- partially just because of the nature of a hood stack, but I feel either way it gives more option for running large exhaust easy (I had built a 3.5" downpipe for the stock turbo, that was a challenge and made things pretty tight back there.. I know some have gone larger but I'm not sure I'm capable).

The other thing is it gets the turbo out of that hole in the valley... Not a huge deal but I like having a little more room around everything... Hopefully the longer pedestal doesn't cause noticeable extra lag??

Thanks!

I think the only lag you'll experience will be caused from less heat retention in the turbine housing due to the short exhaust, and the sharp 90 the air has to negotiate in your IC routing

Got it running!!.... No hood stack yet.. Everything looks good but it won't rev past 2k. I thought I had everything squared away in the tune for this issue... Guess not... Any help??!
