First I apologize for the serious teaser and putting up pics of a project without results and dyno's because there are none. And who knows how long it could be before I go any further it could be a year or more! I just love hearing the ideas suggestions, feedback and knowlege you all have to offer. Isn't that a bulk of what we are here for? :) Well as many of you know I am currently underway with the Supercharger setup. It has been a very slow process but is still underway and the manifold for it is now being welded from what I understand.

I could not get over how much I loved Hotlava's tt setup and it overcame me. So I figured at some point in the future I also wanted to do a tt setup and began slowly buying the additional pieces it would take to do so (being that many are the same, such as injectors, fuel pump monitoring gauges and what not). Then last week my car decide to get some garage time (it broke down later found to be a broken axle, Ebay? I think it was tsk tsk). But none the less it was a perfect excuse to play while she was down so I started to look at how I would eventually want my tt to be setup. What better way than to play. It helps kill concepts that look good in your head given the (not so) workable space; a few of my ideas have since died. But long story short this is where I am at so far. Now that my wife knows that it is just a broken axle I only have shipping time to continue playing before having to put her back together again.

A couple quick notes

-No this will not be done/completed for a very very long time.-This is very new to me so I would be the last to ask for suggestions though I love to share ideas.
-Yes the supercharger project is still underway and taking precedence over this.

-No I did not wake up one morning and say I am going to do a Legend Twin turbo setup during breakfast (sorry Hybird, that just kills me lol)
-No I am not going to be using PVC intercooler piping it is just cheaper to hack away at till I figure how I am going to do it when the time comes.
-I have also read up on some articles of Twin vs. Single and each seem to have there advantages from knowlegable members of their respective forums.
-cheap clamps will be replaced with t-clamps.

Ok the book is done here's the pics. (excuse the mess my garage is at war)
also please forgive the ugly "stand in" mesh and terrible paint, looks will come last. I don't want to tear it up after doing body work and paint.

This one concerns me, there is not much rook and there is a damn brake fluid line that may need to be relocated. wires and hoses I don't mind moving brake, AC, and power steering lines I am not so happy/experinced with.
Image


Hopefully at some point I will be done destroying my car and be able to build it up like the one in my head lol.

-Tip- If you get a new intercooler or radiator, cover the fins with cardboard until it is fully installed so you don't damage the fins during installation :hide:

PS. The purple finish and and nice shiney engine bay will be back in time. it was too hard to maintain and not scratch to hell while getting a bug of some sort and doing stuff like ^ this. I think eventually I will powdercoat vs. paint though.

Well unfortunately the bayis in a under construction stae so you will really have to wait to see what it will truly look like but here is a hold over pic from a few pages back, it is very full right now

Lol, all I can say is damn, what a mess lol. You should also change the shocks for the hood lol.
 
#708 ·
*nods*yeah.. that bright blue doesn't fit... or is that just something holding up the hood? nice cleaning job on the motor parts.

only thing i can think of that would rally make it pop, is to get some highheat metal paint for the turbo. that'd pull it all together nicely.

also.. when you're all done... plastic and tape off everything beside the shock mounts and the rad support... then tape off all the little nuts and bolts... then plastic and tape the fenders slightly below where it 45` bends at the top *to where you can still see the fender's mounting side in the bay* then do an over spray of gloss white. that'll get rid of any small imperfections that are right up close when you first open the hood. ;]

:woot: Turbos are done I will be picking them up tomorrow :D

Lol, the blue thing is a broom stick that is holding up the hood I will one day get something nice to replace it. But I don't have hood struts because it is a Carbon Fiber hood and the compression as higher than I feel good about. And this is the worst teh engine has looked since it has been in it (see sig). But yeah it is going to get some jet hotting and some powder coating and then once I recoop. from all this mess I will get to the body work and fill teh excess holes and paint teh engine bay. I am sticking to my plan :) So it will be a full fledge make over for her.

Ok I can rest a little easier about the exhaust routing under and behind the power steering. In fact I will admit that I contemplated daily whether I was going to attempt to swap the PS to the other side to avoid flow restriction, but I feel pretty good about it now. And yes it is mandrel bent :2cool:

Image


The tape disguises it but the bend is quite acceptaple
Image


Excuse the pluming that it is leaning against I had to support the pipe.

The turbos (blades) themsleves are actaully the same size however one compressor housing is actually a M11 and the other is a M10 but they are both upgraded from the original size and they are sexy. It is a little deceptive though because of the compressor housing size one also appears to be a little bored out but I figure what I will do is take the bored out one and place that on the side that has the longest distance to the intake. The corrugated hose also came in yesterday and I might get away with the one 48" hose.

Its not a race and I don't mind, it would be nice to see his full build before I am done lol :) But no set ETA I happy to be at a point where I actually can see a light at the end of the tunnel.

Weld exhaust (unknown)

have the lines for teh FPR and fuel filter made (Monday)

A little bit more cutting where the piping from the air filter to teh compressor goes (this weekend)

Cut the holes in teh frame for the drain lines (this weekend)

Buy the filters and 3 in elbows for the turbos (possibly this weekend)

Possibly buy a set of external wastegates (unknown)

Cut the piping for the lower radiator hose (this weekend)

Put everything back together (as I finish it up)

Tuning and getting it to accept her added psi (who knows)

This is all very new to me so I am just taking my time to do it one step at a time with some steps here and there combined if the correlate to one another or can give me a chance to take a break from a step that I am frustrated with. But all in all once it is done she will be good tilll teh HG blows and I o-ring the bolck and put the TII heads on. But it is snowing alot out here and the roads are horrible so she wont see the streets for some time anyway (unless a clear snow free sunny day comes along) :D.

Well regressive updates lol. I was not satisfied with the way the magnaflow y is constructed nor the way it forced me to position the piping and all the difficulty it would have caused to place the exhaust piping so I made a new Y that better met my needs and am making some minor adjustments to get it to work out. I also found away to route te stainless steel lower radiator hose.
 
#722 ·
Ok time for a few pics not much new stuff to see I have not had time to work on it lately

a variation of the Y that will replace the Magnaflow
Image


Image


some shots of the revised Y in place
Image


I need a 1.5" 90 deg. bend for teh lower radiator inlet

hopefully your fan doesn't melt being that close to the exhaust.. i forgot if you said you were going to wrap the exhaust pipes or not
 
#724 ·
Yeah I am going to bring the downpipe toward the engine about another inch and I do plan to get it and the headers Jet hotted in crome once I am done. I hear it provides better heat protection than exhaust wrap and will have a much nicer look to it. if all else fails I will flip the fan to the ohther side since there is enough room between it and the intercooler even with the oil cooler there which will eventually have cold air ducted to it.
 
#725 ·
Ok I think I am finally satisfied to the point where I am ready to have the front half of the exhaust welded so here comes more of the same, unless you have a keen eye and of course the obvious which is the passenger side is complete

This pic is so you feel you get to see something new :)

In a box at the moment there location remains unchanged.

because we have a v6 instead of an inline 6, its gonna be pretty messy when we mount the turbo or turbos up front, the only way to avoid all that mess is to make a rear mount turbo system where the turbo is mounted right after the y merge and then you'll only really see the intake and charge pipes for the turbo, if I ever get some extra money to throw around, that is what ill be doing.

#733 ·
Telion how come you didn't bend the exhaust pipes down imediately on the exhaust part of the turbo and run the driver side pipe towards the passenger side by the crank and not how you did? To me this could have been cleaned up alot more using a few more bends

With limited fab experience and a home garage, theres only so much a person can do. I ran into that problem too and I have much more fab experience.
Also just in case, please don't pretend like you've done all your own fab work, because I will never believe you.
Now car2n, that's a fabricator from start to finish.

I never claimed to do all my own fabrication though. I just have a good personal fabricator.

I just don't want someone to pay to have something done when it looks like it could be fixed pretty easily. Could have used all steel piping and welded it together with a typical house welder and then had someone replicate all the piping for him in whatever he wants it to be.

Point I was tring to imply is that you go around many performance threads picking things apart. Thats fine granted you earned the right to do so.
You have a nice shiny powder coated engine, I give you that much.
All show and no go. I already know the rebuttle, your just holding out. Somthing tells me you need to find new help because, it doesnt take that long once your already up and running, and turbo running you have claimed.
