yeah
i was talking to brian reilly at gtpro last year around january or so and they were installing a kit on someones car. i also asked brian lafuente about the kit and he said it wasnt worth the price...or something to that affect, but i dont want to misinform, so i guess they should come out and tell us whats up.

Here is what we found...
Spool-up?? rather poor, 3500rpm's to see 8psi.
Build quality? poor.. If you are going internal wastegate, you will have to cut and re weld the bracket that holds the actuator bracket, and also rotate the comp. housing. The front intercooler pipe smashes the top rad. hose about 1 1/2", not good.. I/C pipes fit terribly, nothing bolted straight up, and , many brackets were VERY far off, and could not be bolted down. Headers have port blockage which is not good and poor materials (unknown stainlees steel) not graded such as 304 or 321. The oil feed and drain lines were a complete joke.. They were made from copper tubing spray painted with oiling orafices that looked like a pinhole. I/C piping has no beadrolls and fit very poor, we're afraid to really crank the boost in fear of blowing pipes off.
HP? I feel many of our other TD04 guys would smoke a VF22 car..
Comp wheel size? smaller than a 357 mag. wheel.
All in all we were VERY VERY dissapointed with the kit to say the least.
Oh, and to top it of, the turbos supplied? they are USED, not rebuilt, not new, but flat out used. Both turbos did NOT spin freely, and one was really sticky, our standard bearing turbos spun more freely.
Take our review for what it is, a first hand experiance with the use/install.

Re: finally...
Check out the compressor flow maps in the Garage section on Jeff Lucius's site: www.stealth316.com
- Brian....anxiously awaiting adapter plates to bolt up 14Bs.
If you're going to go with TD05s, go with 14Bs or big 16Gs. The 14Bs look like they'll actually provide more air to the engine than 15Gs! The small 16g offers little to no gain over the 15G. The big 16G looks well suited to BIG (25-30 PSI!) boost.93V said:

I'm not going to give a primer on how to read compressor maps here; Jeff gives a very thorough expaination on his site.
Suffice it to say that you can't evaluate a turbo based on "CFM" as people on this board seem to like to do. The amount of air a turbo will compress depends not only on the speed of the compressor wheel, but also on the pressure it must push against. Because of this, a turbo will behave differently on a 2L engine (ie Eclipse) than it will on a 1.5L engine (half a 3/S).
It's a long and involved explaination - if you're really interested read Jeff's great page:
http://www.stealth316.com/2-3s-compflowmaps.htm
If you want the short and sweet version, skip to the near the bottom of the page where he lists "Flow Maps with Modified Engine Demand Lines". On each of these maps, Jeff has overlayed the behavior for a theoretical modified 3/S engine.
Bigger, as it turns out, is not necessarily better for our application. According to his calculations, the turbos can hold the following boosts to redline:
- 15G can hold 20 PSI to redline
- 14B can hold 25 PSI
- Small 16G can hold around 23 PSI
I addition, the 14B provides better midrange boost than either turbo as well. All this makes the 14B actually better than the 15G or small 16G for our engine.
It may be counter-intuitive, but that's the way the math works out. I think as we see more people playing with TD05 turbos, we'll see this in real world results.

It all boils down to what you want out of it.. TD05's are not a bad deal in terms of perf., just has to boil down to set-up, ease of install and caricteristics of the turbo.
