Hey Guys,
I was wondering if anyone had any experience with putting a "lite" turbo setup on. I don't want to lose reliability or spend thousands, I just want to add a little pep. I was thinking a tb02 or a t25. Maybe something that came off a stock turboed car like an audi tt or something. I have heard that if I am only running 5psi I don't need injectors, intercooler, and I can get away with a lot less of electronics as well. Can someone set me straight?

Check out turbomiata.net lots of forced induction information there. I am running 7lbs of boost in my 94 1.8 with a garrett2560, an intercooler, stock injectors, and megasquirt for fuel/timing. You will need to address fuel and timing, either with bandaids or with a standalone ecu.

To answer your question, yes u can run 5lbs no intercooler, stock injectors,.but.u will want to run a aftermarket ecu, or run a bandaided set up using a rising rate fuel pressure regulator, and an o2 clamp, or something to control timing.

Look at spending around 1000 if u want to fix it.every week, and 2000 if u want to have more time drivng rather than fixing.

Yeah, that is what I don't want to get into. In the summer this is my wife's daily driver. I just wanted some extra pep without any of the headache.

So how often do you have to mess with it. (I would have asked in the previous post, but I just realized it was the same person!)

small turbo. BEGI Fuel Management Unit, Bipes ACU, O2 clamp. done. simple cheap no major hassles.

oh, you will have the small headache of tapping the oil pan, getting whatever downpipe you have to fit properly (if you are going cheap).

but +1 for goint to MT.net, or M.net for additional info.

Considered supercharger? Simple bolt on. Not too expensive. And always fun :)
I am more of a turbo person. Also my wife's commute is 105miles round trip. So I like the idea that she can stay out of boost for the most part. I just want her to have a little extra for passing.

I think a low-boost, well- sorted turbo setup would be less of a hassle. No extra belts to deal with/funky idle. Just grab an off the shelf BEGI-S Shanghai kit and be done with it. Spring for the SS oil return and a turbo heat shield so you don't need to worry about them.

:woolery: Then don't turbo it. Any turbo setup that doesn't have any headaches costs a lot more than $1,000. Want something that adds pep and doesn't have any issues? Get a small supercharger. There are lots of reasons that we prefer turbos over superchargers for racing applications, but if you want to avoid the headaches AND want to keep it cheap, don't get a turbo.

Turbos have 1000 more components than superchargers, which can all wear out or break, and produce ridiculous amounts of heat, which stresses EVERYTHING else on the car. Even with a low-power simple kit like a BEGI-S, you'll find yourself needing to fabricate heat shields, tweak things, adjust the wastegate, drill and tap the oil pan, replace coolant lines, troubleshoot oil drain leaks, etc. etc.

You'll also need additional things for a turbo kit that you don't need for a supercharger - a boost gauge for example, because a wastegate failure can change the boost output, whereas a supercharger only produces one set psi depending on your pulley choice. No need to monitor your boost output.

i'm no boost freak, so i dont have the knowledge most do about turbos, but even then, i doubt it'd be less of a hassle, even with the begi kit.

S/c consist of the blower, pulley, belt, and crossover tube. super simple. i installed mine in approx. 2 hours... i sold my jrsc for $900 w/ 40k miles. still strong, and as far as i know, the buyer is still running it. 5-6psi, nice kick when u step on it, only boosting when u floor it, so gas wasnt an issue. i loved it.

anywayz, lets not make this another s/c vs. turbo thread.
op, good luck with ur search, i was just curious to see if u had considered the s/c.

This is great input. And frankly I never really think of SC, mostly because I am a suby guy and have owned a few turbo cars. I just liked driving around and watching the boost gauge sit at zero until I really get on it. I truly don't have a good understanding of SC and just thought that they boosted the car equally based on your rpms. Where as turbos need time to spool and only really get going 3.5krpm (obviously this depends on the turbo).

There's a bypass valve, you're not in positive pressure all the time. When you get on it, the bypass closes and you have instant (more or less) boost based on whatever rpm you're running at. Depending on the setup, you can easily have full spool at 3k (gt2554r/tubular manifold/separated gases downpipe).

Just to add to confusion, how small of a turbo can you get? (response wise, in conparo to supercharger, I don't wanna loose energy to that parasitic effect of the SC)

2.
If I go boosted I'm ...aw! Screw it! Begi kit 1 it is. Is there a cheaper kit?
As, I would pay 3K for 200+hp but if I'm looking for less, what would you recommend? For 2K and some shells?

3.
And last how does drivability differ from stock:turbo and s/c? (partial throttle)

If you decide to go turbo I'd suggest looking at the BEGI kits, especially if you're not a pretty serious tinkerer or if the car is going to be a DD (which you say it will). The shanghai kits start at around $1600 with EVERYTHING you need, ready to bolt on. You can slowly upgrade from there if you want more power, or leave it as is and have a nice reliable setup. Your wife, if she's like mine, would probably want more power down the road, so it's nice to have something you can slowly and relatively cheaply upgrade, where a supercharger is a little more difficult to upgrade in small increments.
