Turbo kit from Ebay - whatr some opinions?

[mikeukrainetz]

I have gone back to this item I dont know how many times to take a look, obviously its not high quality stuff but short of a fuel computer anyone think this crap is worth a try?

I personally would hold back the impulsive tendency and wait for a proper turbo kit.

But if you are really comfortable with the work involved and are prepared to source missing parts and components, I say do it. I've witnessed self installed (aka hack job) turbos on late model Hondas and they were pretty functional (and good).

It fits any car?

plus a custom exhaust header, plus custom piping, plus the fuel control, plus the blown engine cost's, plus the cost of running higher octane fuel, plus the extra wear on the tranny/clutch, plus the torque steer.... i say go for it, someone has to be the first, i'll wait for trd's products, plug and play!!

that turbo is the same turbo that SSautochrom sales, otherwise pure crap made in china. do a general search on the web about SS autochrome.

[spkrman]

doesnt look that bad to me? I did search and saw mixed reviews... but where there are mixed reviews, that means there are some positives :)

Add it up and see how much it saves you as opposed to ebaying a used turbo, and just sourcing all the parts seperately. I've heard of some kits, with some ebay expertise, getting all new stuff for under 1200.

I dont see the turbo itself being all that impossible, the tuning of it is all that worries me.

If I was looking for a low-cost way to get high horsepower gains, I wouldn't be thinking of a turbo. I would be thinking nitrous.

Forced induction is a big step. It requires a proper tuning of the ECU which will (likely) cost you hundreds at your local reputable dyno shop, and in the case of a turbo will probably require overseas parts or custom parts for proper fitment. It definitely isn't a good area of modification to skimp on. For that reason, I wouldn't touch the turbo listed here with a 49 1/2 foot pole.

The Yaris's power band screams supercharger to me anyway. A supercharged and sprayed Yaris would be quite the quick little kart.

[acrbill]

First off, that turbo is absolute garbage. It will fail in short order.

Second, its wayy to big for a 1.5L motor.

Unless your pushing 800hp most ebay intercoolers will work fine.

I actually have that same exact boost controller and BOV on my PT cruiser.

The boost controller works fine, but the BOV had some initial quality issues. The casting for the body was horrid, so much so that there was a hole in the body that I needed to epoxy. The internals look pretty decent.

I would go with a garrett gt28r turbo. It would be a close match for the yaris motor.

NOS would be fun, I'm considering headin in that direction instead of a turbo... the turbo is so $. Even a small shot of NOS would be pretty sweet.

[acrbill]

You will never be happy with nitrous. Since the motor would only be able to stand a very small "shot" you would barely feel it. Nitrous is not really a street friendly mod. Plus at $50 a refill it will get old really fast.

[keesue]

The thing one needs to consider is the existing compression ratio of the engine along with several other factors; i.e, the added fuel pressure requirements, running premium fuel, recalibrating the ECU to enrichen as boost is applied as well as the longevity of the engine components. I'm not sure, but the turbo RS model may have different componens (pistons and rods) to handle the pressure along with a recalibrated ECU. That is generally the case when the factory produces a turbo. This is not to say it can't be done after the fact but a little research and extreme care should be considered. I'm sure some one will produce the right kit for it.

[mikeukrainetz]

There are correct kits already for this application by numerous compaines, Blitz being one example for the Xb but check out the price tag. Im not condoning buying cheap shit parts but I dont want to pay 'Hilfiger' prices for the same shit parts. I do pretty much all my own wrenching, always have and it doesnt bother me a bit, I just hate all this computer controlled stuff as 'efficient' and 'power producing' as it may be. Nothing sounds as good or as grin enducing than a carbureted big block ford or chev...

Ive never done a turbo, I just bought an 86 volvo turbo wagon and love it. Theres an awsome shop in my area that does performance tuning and dyno for a decent price (so Ive heard) and tons of custom machine shops (CNC, gotta love it). I do all my own CAD design and can produce the necessary files for CNC to save a bundle in design but dont have a flow bench or equivalent software for testing.

Nitrous is great if your street racing or running the quarter and not much else, it costs $100 to fill a 10lb tank here.

The compression issue is fairly easy to deal with - see this link for a perfect example http://www.eiptuning.com/eip/headgaskets.html

Maybe (from what response Ive got) Ill look for a more appropriate turbo but what about the other parts, tubes, hoses, intercooler? From what Ive found a decent intercooler can run about $300 plus. I guess I was more interested in the fact it came as a total kit (less controller). Personally I think it would be easier to retro fit an existing GM supercharger but am concerned with the amount of power that can be produced from such a small displacement without extremely high boost.

[Katana]

Guys just wait up for the Blitz kit...

[mikeukrainetz]

I wont have any choice but to wait until spring / early summer but hate the fact these things are going for 4 grand.

[Katana]

I wouldn't trust them in my car...

[DTM_Yaris]

That 57 trim is a copy of a Garret bastard turbo. Very inefficient and not worth getting. Never mind the only thing that would probably fit on that "kit" is the BOV. The rest is way to big for a 1.5l
Just my 2 cents

[mikeukrainetz]

Ive never owned / built a turbo except for my wifes volvo we just bought so Im still playing catch-up on FI setups other than supercharging (Ive stuck with ford / chev V8s never imports) the principles are pretty much the same.
I understand the size may be oversize for the Yaris its the only kit that was available at the time to use for asking the question.
If I wasnt now seriously considering an engine swap I would dig a little deeper into the FI setups.

Quick question on the turbos - is it then worth it to just buy a Garret or other turbo and use a 'kit' for the rest of the parts? More or less doubling the cost but getting a decent turbo? Vibrant here in canada sells intercoolers but theyre also around 300+ a piece.

[paultyler_82]

I've been trying to scavenge the junkyards now for some time looking for a Dodge Shelby CSX-VNT ... I want one of those Garret VNTs, granted I'd have to make some sort of custom controller to control the vanes, but a turbo with practically no lag, and a shorter spool up time is just so appealing... I've been talking to the people at Garret, but they don't seem to want to sell single VNTs to a non OEM

[DTM_Yaris]

The best turbo for this car in stock form is a GT22. Good for about 295 WHP. Very efficient to about 14psi.
But as far as cost is concerned I would go with a basic Garret T25, from the old 80's sunbirds. Similar to the 300zx turbo's in the past. Spool up would be nice and very reliable. Very cost effective and can be plumbed much easier than and oversized hybrid like the one on ebay. If you need help getting going let me know. I would be more than happy to lead you in the right direction.

[DTM_Yaris]

Also about intercoolers, on a stock car without any internal modifications to the engine and low boost, there is NO need for external intercooling. It seems a bit backwards to state, but it is true.
Such little boost pressure (5-8 psi), there isn't a need for much of the hardware they try to sell you.
The piping would be eliminated and throttle response would be a tad bit better.
There are better ways to cool the air charge on low PSI setups.

[eTiMaGo]

such as? water/alcohol injection?

[DTM_Yaris]

Correct

[eTiMaGo]

Correct

Most interesting... :wink:

From how much boost onward can you see a real advantage to using an intercooler?

I'll be sure to follow your progress (bit of a turbo n00b), I am most likely going to go turbo next year, then use and abuse this engine till it's really dead, then swap it...

[paultyler_82]

The VNTs in the CSX-VNT were very similar to Garrett's standard T25 but the special thing was that they featured variable nozzles - small vanes surounding the exhaust turbine. At low turbo speeds, the vanes close to decrease the volume of the housing, causing more rapid acceleration of the compressor for faster spool-up. When it was up to speed the vanes open and increase the airflow, letting the boost level rise. They also took over the function of the wastegate, so in their applications, there is no external wastegate. I'd say they're probably good for about 15 psi, but on the CSX they were set at a maximum of 12 psi. Again... it would be a bit of an involved install and you'd have to build your own controller and put in some new sensors, but it would definately be unique.

Anyway, on to the intercooler thing, at some point, the piping and the size of the intercooler will contribute more complications and lag to your setup than the intercooler is actually helping, I've seen many low psi setups where people just ditch the notion of any kind of cooling, and it works, every setup is different though, and I guess the Yaris world is just going to have to see what works best for us.

It is dependant on turbo manufacturer, wheel efficiency etc. BUT on say a T25, you will need to see 10 psi and above.
Otherwise the alky injection will create a denser mixture without all the need for complicated plumbing and additional weight to be added to the car.
More importantly, these cars were not designed for large front mount intercoolers. Thus, you would be creating a problem with the airflow going to the radiator. It would block 90 percent of the incomming cool charge and may cause overheating and damge to the engine.

[paultyler_82]

there are always custom intercooler setups as well... I've seen some pretty wicked ones, including one that sat at the bottom of the bay and got its cold air from underneath the car

interesting, but better not be any rocks or pebbles on the road to get kicked up!

as for a FMIC on the Yaris, a different front bumper such as the C-ONE looks like it could accomodate one.

[mikeukrainetz]

I dont think placement of an intercooler (provided its not huge) would be a big deal its everything else.
Curious about the intercooler not being a necessity at low boost - we have a turbo volvo that runs at 7.5psi - the lag is horrible but once it spools up it goes like shit. Without the intercooler it supposedly would be a completely different machine, less boost, more heat, more lag.
Maybe someone could give a little advice on that?

Its the complication / price of the FI setups thats driving me toward an engine swap.

[punch]

I've decided to hold out for whatever trd comes up with!

The volvo's have VERY restrictive cores. The only reason they run low boost to begin with. The system would have horrible pressure drop data with much more boost.
Don't get me wrong you need intercooling, but not necessarily with a heat exchanger. A chemical cooling agent like alcohol is a much better option.

[graywolf_14]

the dodge colt turbo didnt come intercooled. I was going to swap a colt turbo onto my talon with no intercooler to start with just to get into turbos.
