::Twin Turbo'd Dohc Progress Pics::

[Guest]

my question is how is it going to fit. it looks like it is backwards. if you put that in a w body wont it hit the computer and the coolant tank. i thought it was easier to move the battery.

Reading skilzz pwnz joo!

Here are pics of my progress so far with my twin turbo?d & intercooled 3.4 Dohc that is going in my 94 Trans Am.

I can't wait to see/hear how this works.

Can you post a compressor map for those turbos? I may be interested in one or both. Thanks

That looks amazing. I can't wait to see it done. What welder are you using?

Sorry I havent replied to anyones questions, havent been hear to check the post in a while.

First off, pertaining to my engine choice. I chose this engine based purely on potential and originality, especially its potential to breathe. 4 valves per cylinder are a much more attractive option to me than the standard deuce in a 3.8 or 4.3. Granted, either one of the formentioned options would be easier to get much stronger (and cheaper) parts for and would therefor result in many less headaches for me, buts that part of the fun for me is making something I know I wont see anywhere I go. As far as why there isnt a V8 riding between those fenders is quite simple, anyone can make a V8 go fast...anyone. Its nothing special to see some big burly tear the pavement from the roadbed V8 muscle car, needless to say its not everyday you see what Im working on doing.

This is actually the final project I have left on this car, there isnt anything else that can be done. I bought this car when I was 14 and had been saving up for it and what I would do to it since I was 12 (I'm now 20 and have never hired out a second of labor on it) its my dream car. I have a stereo that could blow the chrome off a hitch ball(Alpine Indash Dvd/6.5 Lcd head unit, Alpine Dvd Nav, Alpine 14 band digital EQ, 3 JL 10w6's pushed by a JL 500/1 and a JL250/1, A JL 300/4 pushing a JL 3-way XR series comp system up front and a JL 2-way XR series comp system in the back, and 2 sets of MB Quart 3.5"'s for front and rear fill) yet it barely gets played above a whisper...and as close to a full race suspension as you will get on the street (4 wheel coilovers, 4-wheels disc with a C5 changeover using 6 piston calipers in the front and 4 pistons in the rear, subframe braces, chromoly k member, LCA's and A arms, adj panhard bar and torque arm, riding on 17x10 Fittipaldi's wrapped in BFGoodrich G-Force KD's)...it can take corners so fast you think your eyes are going to be pulled out your ear. I even taught myself to do bodywork just so I could repaint this car. I guarantee I will have some video of her up and running for you all when it gets completed, which I am hoping to be by the end of this coming summer if all goes well.

As for the request for compressor maps, about half way down this page are links to a plethora of maps

http://www.stealth316.com/2-3s-compflowmaps.htm

the turbos that I have on there right now are TE04H's which are also known as TD04-13G's, which is what they are listed under on this site. What I will be upgrading to is most likely the TD05H-14B's.

And as to what welder(s) I am using. The welder of choice for the work that has to look pretty and all aluminum is my Miller 180SD Squarewave TIG, for tacking and everything else is my Marquette M12210 MIG, easily the best MIG I have ever used, everyone still tries to tell me Millermatics are better but I personally do not like them as well...which is why I sold mine to buy this MIG. If you can find one, buy one! Because they no longer make them. Assisting in the metal fab duties is also a Thermodynamics Plasma cutter...which is a godsend.

And even though "d.o.h.c." didnt realize what it was going in, its still a legitimate question! I will have to take some pics of it mocked up in the engine bay so you can see what I'm talking about, tight doesnt even begin to describe it.

Thanks to all for the comments and compliments, nothing keeps ya going like people telling you what your doin kicks ass

ECU

We have just turbo'ed a 3.6 ltr GM Holden Commodore in Australia.
We used an EMS computer as it is much easier to tune than the Haltech.
Did you have a particular reason for choosing it?

[Dave96z34]

bump any updates?

[Will'sFiero]

Ok, i figured that was what the 2 tubes were for but didnt see it. Are you boosting 1 side with 1 turbo? Any thoughts on unequal pressure from different banks causing problems? I would have something connecting both plenums, more than a tube anyway.

If he feeds the right bank from the left turbo and vice versa, the system will be self-balancing even without fancy electronics.

agreed, prolly the easiest way to do it and one of the safest without running an equalizing tube for the manifolds
