Single turbo, what's it gonna take?
Single turbo, what's it gonna take?
Ok, I have heard that twin turbos are easier than a fat single turbo on a third gen, but I like the idea of one big turbo that can pump out tons of boost better. I have done some fiddling on Dyno 2000, and i like the idea of launching with little or no boost, so that the tires don't go up in smoke, and then feeling the boost kick in as I accelerate. I have an automatic too, so i won't lose boost between shifts right? Ok, heres the real questions though... Who makes turbo headers for the third gen? For a single turbo do I have to make some equal length thing so that all of my exhaust goes through the turbo? Can I just use one turbo header? What about intercooling? Is 10 psi on 9:1 compression gonna be ok on pump gas? How hard IS putting a turbo on a third gen? What kind of pop off valve do I need? How much realistically should I expect to spend? Am I gonna have to get ANOTHER chip burned for this thing?
But anyway, I am dead set on a single turbo, twin turbos just arent my style. I'd rather spray it than go twin. Oh, I street race, which is why the low power off of an idle is desireable, because as of now I have an open diff, and I have wheelspin problems as it is. Plus, hearing the roar of a V8, and the the hiss of a pop off valve will make little low slung hondas **** their shorts. I need to be pointed in the right direction, i hope you all can help.

Do some searching on this forum. I have posted some photos of single turbo setups on 3rd gens. No one makes a kit for our cars. Anything you build is most likely going to require you to remove your AC and the box that houses all of its components. I dont have an AC box period. I cut a plate to bolt on over that spot.
You could get by with a non AC box in its place.
The k-member is a difficult item to work around.
Unless you can TIG weld, or know someone who can, expect to pay around $3000 for for someone to fabricate a set of headers and a crossover pipe. Thats not including purchasing a turbo, intercooler, wastegate and blowoff valve.
Now, my situation:
I purchased 1 3/4" 16 ga,. 304stainless u-bends from www.burnsstainless.com and have cut and fit each primary tube into a set of flanges I cut on a CNC table where I work. Even with all the advantages I have, I still have over $700 in materials alone. Most header builders will use more expensive 321 stainless if you go to them for a set of headers. I got lucky, and a friend of mine who can TIG weld is finishing my headers. I am mearly cutting and tacking them together.
The last order of business concerning the turbo will be some kind of boost control wether it be a manually built controller or an expensive electronic controller.
I bought a BIG turbo which cost nearly $1800. The wastegate Ive purchased as well and it was $500. I still have to purchase a blowoff valve and intercooler (NOT CHEAP) as well.
These are the mechanics of fitting the turbo on the car.
The other part is designing your fuel system to handle it. Not enough fuel under boost, and your going to destroy your pistons in very short order. At the VERY LEAST, youd need an inline fuel pump and an FMU just to make sure you have fueling. I use Speed Pro which is an aftermarket EFI control system that replaced my factory TPI wiring and ECM.
As you can see, its quite involved. Hope your ready for a lot of work.
Check out my webpage for photos of my setup.
