Lusting for a twin turbo setup, and would like (helpful) ideas

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.

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.

or like this?

I am afraid that conversation would take us too far off topic.

Not much news today other than I have decided to go forward with relocating the fusebox, and re-routing the wiring to the relay box which will stay in it's current location

Lol cool, you should post more pics of your build in your thread or start a thread dedicated to it. I know people our going this route but everyone is so quiet about what they are doing (Kinda why I am all out with posting every step of my build.

More pics of the wiring mess I made and then cleaned up I pulled each tangled pin from the connector, then untangled it and put it back in its place in the connector; damn did that suck, the pins just didn't wanna come out willingly.

The mess

And a couple hours later. I still need to solder in the 8 or so wires that needed to be extended to make this a go, gut so far so good.

When i first started learning electronics, I had nightmares that looked like this picture. I know i've said it before but i really appreciate that you have put every step in this thread, including the problems. Its inspired me to do my own turbo build, but on a 4 cylinder, and completely from junkyard parts. Thats where I get my kicks, building something from nothing. Im preparing in case McCain gets elected, and the world ends up like Mad Max. Ill be set.

Thanks everyone for your support, lol when I looked at the first pic I thought to myself what have I done? What am I doing, and how many simultaneous projects is this on the car at one time, so Car2n I can only imagine what your going through. But I know there will be an end. I think being able to see the end result of each mini-project in my mind helps me understand and get to teh big picture.

lol, thank you for the advice but with the DSM's I can cut the fuel on my stock setup by 65% (meaning this is what is in excess and available for F/I) so I will run them and feel that they will be more than adequate, thanks though. I prefer to run what's adequate.

I got a question, slightly off topic, but the people who I think can offer me some info are the ones reading this thread..Telion,Kho,DV8,Buzzard..

In hillbilly land, the answer to any EFI/ECU question is: Put a Holley on it. I have experience with rewiring ECU plugs for different injection setups, but as far as how values are changed on the ECU, that is a mystery to me.

Now im not asking you guys to explain how this is done, but if you know of any good resource materials, that would be sweet.

I also want to know if all Honda ECUs can be chipped. OBD0/OBD1/OBD2 etc, and if any of them are easier to chip than the others.

So again, I realize this is pretty off topic, but Telion is going to have a lot of ECU stuff to do, so I thought it might be ok to ask..

PGMFI.org is where I would point you toward

Now back to the topic at hand (avoiding Engine management for now)

I was able to get the relocation of the fusebox 90% complete. Now I just need to get it mounted into place :)

Thanks for link.

I like how you've managed to tuck the whole harness into the fender.

can you post a pic from the front where we can see the bay with the harness down the side, or are you saving that pic for a bit?

How well do you think that fuse box will work as a clutch:hide:
 
#529 ·
What do you mean, it makes an excellent clutch if I ever get road rage I can just blow a fuse. No need for a frontal shot it is tucked along the side of the fender nice and tight.
 
#532 ·
It should, it is a nice tight tuck, I am even thinking a cylinder style windshield washer reservoir in there :)

Now on a side note I have pondered this for a few days well about a week now should I put a piece of flex pipe in the downpipe between the turbos and the Y incase I decide to swap the turbos or for greater flexability? :dunno:
 
#534 ·
They are unfortunately I broke one though :( good thing there is a GS parked next to it with plenty of spares :)

I am still in limbo on this any opinions good bad whatever, talk to me :dunno:

I really think it would be kind of silly if you spent all this time on those headers and making SURE they were as thick as you wanted, only to feed them straight into... a flex pipe?! I guess it depends on how many miles you would be putting on the car before maybe changing the turbos. If you are just taking a few miles you could just clamp the flexpipe into place to get the fitting. Youd probably have to constantly adjust them for leaks but as a temporary..

I really need to clean everything up as it looks a little discouraging as is.
We Believe In You!
 
#537 ·
Well. . .your response didn't address anything in the thread, welcome back though, and I think in your pic the muffler is sitting a little too close to the ground. my goal will be to tuck it a little better and take out a little bit of the bumper area to accomodate a more flush fit. But scrap my previous question I have decided to only use flexpipe after the Y on the downpipe.
 
#540 ·
Thank you as well :). Clocking the turbos for the moment is the least of my concerns lol. I really need to clean everything up as it looks a little discouraging as is.
 
#543 ·
Thank you, and that makes two of us. As for the map sensor I will just need the one map sensor because it will still get data from the the intake and not the turbos and both turbos are fed into the one intake.

Sorry I should have been more clear the Turbos would mount directly to the headers as planned. I am referring to the exhaust side right before where the down pipes merge into the Y-pipe but I decided against this at this point because I think it will be fine even if I increase the size of the turbos. I am pretty sure that a T3/T4 would be more than adequate down the road. So it would be added difficulty for not much benefit. And thanks fr the encouragement! it always helps.
