XB HKS turbo kit, on an echo

[taKuto]

Well i've purchased an HKS turbo kit designed for the scion XB, and am in the process of getting it fit onto my echo.

The wiring is the easy task since I finally found what looks like a wiring diagram for the fcon mini piggyback off some russian site.
f-con mini piggyback pinouts (http://translate.googleusercontent.com/translate_c?hl=en&ie=UTF8&prev=_t&rurl=translate.google.com&sl=auto&tl=en&twu=1&u=http://forums.drom.ru/gt-forum/t1150933360.html&usg=ALkJrhiUaT6pclqvV8SqoyuljeNmGa2DZg)

From the looks of it,
- HKS uses garrett turbo, I can't identify much else from the nameplate :(
- the oil feed taps from the stock oil pressure sensor location
- this piggyback modifies the TPS signal, guessing it sets TPS to 100% to get open loop, otherwise I'm not sure why else it'd modify TPS.
- missing oil return hose, probably could source one local
- I'm missing all the brackets that comes with the kit, according to this picture of the stock kit:

A few questions I hope a few of you knowledgeable guys could help me with:
1) How should I check the condition of the turbo to determine whether I need it rebuilt?
2) This kit is not intercooled and has no BOV. From what I understand, this kit boosts to 4psi. Is a BOV required for such low pressure?
3) Not water cooled, should I be concerned about anything?

Intercooler is another issue, I will eventually need one (previous owner had lots of issues of overheating) but I will save that for when spring rolls in.

Here's the photo album, didn't post the pictures in case the account bandwidth gets used up.

asking bluevitzRS (either here or yarisfans.com)....he had a greddy turbo kit for an xb which he had in his car for a bit...sounds the same as yours

[cali yaris]

4psi stage 0? sounds good to me.

What do you mean by overheating? The coolant was overheating, or the oil, or what?

Check for shaft play and clean turbine blades, no rubbing, etc. on the turbo. How many miles does it have on it? Sometimes it's better to rebuild than to see it fail.

[taKuto]

Thanks barber, I got to chat with him a while ago and he told me about losing power at high rpm's, maybe he'll chime in on more things to know. I've been going through the greddy kit install for reference since I couldnt find the HKS install instructions, and they do share a lot in common.

HKS throws in a few extra brackets and I have no idea how those go together, or whether I should be concerned. One bracket looks like it's supposed to hold some lines in place, I'm curious as to what that one goes to.

Unknown mileage, so definitely need to get the turbo checked out.

The previous owner was getting a lot of engine codes regarding high intake temperature, so overheating may be exaggerating it. But definitely will benefit from an intercooler.

[cali yaris]

If you isolate the intake from the engine bay as best you can, (wrapping, airbox, etc.) you might be able to get the temps down some.

[Bluevitz-rs]

There was only a few clearance issues I had with the GReddy kit. First was the discharge pipe sat up too high and was holding the hood up about 3 inches. Next was the intake pipe on the turbo was impacting the A/C lines at the firewall, so I just tweaked them up a bit and last was my shift cables were resting on the down pipe. Not sure if it would have been an issue if it was the 5 speed though. I did however have the down pipe wrapped.

I think a lot of the power issues was a result of a horrible factory tune that came with the e-manage. It only hooked to the MAF and injectors, so it had very little control. Other issue was the high intake temps for sure. The power delivery was fine and made power up to about 5500 when it was cold, but as soon as it got up to temp, power started to drop off lower and lower. After the engine was heat soaked, like getting stuck in traffic or in the city, the car made more power N/A over turbo. So I think you should look at some sort of intercooler.

I was looking at getting a air to water setup for around $300.

[taKuto]

Well doesn't look good for me. Got a mechanic to take a look at it today, and took apart the piping. Shaft play is ridiculous, and the fins made contact with the housing. Raging hard, probably going to spend so much just on a rebuild if any of it is even reusable.

[Bluevitz-rs]

Man, that sucks. Can you use a different turbo?

[cali yaris]

Depending on what model it is, we can do a seals/bearings rebuild here fairly inexpensively.

[Scubaru Steve]

sometimes you can fine rebuild kits fairly cheep, under 100. do the work yourself, then send it to a shop to do the balancing.

[taKuto]

Thanks cali, i'm going to try to find someone local first but will give you a shout if I have no luck.

Steve, how would I determine which rebuild kit I need, or is it standard between all garretts? I can't figure out how to read the turbo's nameplate to find out what it is.

[taKuto]

spent some time tearing apart the turbo, the turbine housing was seized pretty well. I just wedged a nickel between one of the bolts, and hammered the wrench to break the seal.
markings on the turbo housings:
turbine housing: 687 59M GARRETT 272-2
compressor housing: DIE M24 A/R.48 GARRETT <WL>

[Bluevitz-rs]

So what are your plans now?

[taKuto]

Decided to just cut my losses. The fins were slightly torn on the compressor side so it's not even in good shape to rebuild. Too frustrated with the kit since I lack the knowledge and money to do anything. I was thinking of buying a used garrett T25 off a 300zx but the tune on the piggyback will probably be useless since it's not the exact same turbo (I don't even know if the piggyback works because the wiring was guess work without proper wiring diagrams).

Probably just wasted enough money to have pieced together a kit myself.

[viggen]

Sorry to hear that you gave up, but looking at the pictures that Turbo was a oil cooker:eek:

Keep us in the loop with your future mods, echo looks good:thumbup:

[Scubaru Steve]

i have a greddy turbo kit laying around.

[taKuto]

why haven't you put it on? :smile:

[taKuto]

Purchased a set of 300zx turbos, their specs are the same (.48A/R comp, .63A/R exh) so all that's needed was to swap the compressor housing and clock the turbo.

Next, installed the AEM UEGO wideband and STRI XLine P1 oil temp/pressure & boost gauges which i've purchased without sender units. Gauges are pretty useless, until I find compatible sender units to work them. Figured out the oil temp one is probably compatible with an autometer 2258 after trying some resistors, oil pressure gauge I didn't get a chance to test yet, but did not look like the autometer 2242.

Here's where i'm at now: shifter cables are blocking the turbo from fitting (too stiff to push away, and even if moved they'll still be resting on the turbo). Took this far to finally figure out that bracket I didn't receive from seller was the shifter cable bracket. Needless to say, seller won't be reachable for this piece since he sold the car.

Have to figure out how to move these shifter cables somehow, any ideas? I have a feeling I probably have to make a custom bracket. Until then, i'm running on recirc mode because exhaust is leaking, likely from the metal gasket that meets the block and manifold which I can't find.

[discomark10]

reguarding the larger turbo, a bigger turbo will move more air which can be controlled by the wastegate

[cali yaris]

^ And creates more lag. The turbo should be matched to desired horsepower. If you aren't going over 200-250, a GT25 is perfect for this motor.

I have a GT28, and it takes about 500-600 more rpm to spool up than the GT25 did.

[taKuto]

??? dont think i mentioned anything about a larger turbo on the last post.

[Scubaru Steve]

i removed the greddy kit and replaced the manifold / down pipe, go find a used
gt25 from a nissan sr20. i found mine for under $100 (if yours doesnt suit it.
and its in very decent shape. has a .68 a/r for the exhaust which is a very nice balance for the size and car.
the compressor housing is also a nice .8 a/r bigger turbo for a 1.5L but
defiantly not small.
the greddy kit would still push 7psi at read line but the
manifold / turbine housing was so small it choked the exhaust and could move
enough air through it. pics of setups. ignore the dc in the middle.

ps these kits
are for an xb and used on an 02 echo sedan.

Where did U find that manafold and downpipe? Those look nice. Does your turbo clear the a/c lines? On my yaris they come out of the fire wall directly behind the valve cover.

[Bluevitz-rs]

They're OBX

That's the main reason I'm not going to turbo myn! I've even got a suitable turbo in a box.. just dont want to lose the ac

[cali yaris]

You didn't; but discomark did, and I posted right after him in response to his post.

[cali yaris]

My turbo cleared all the a/c just fine. I removed the a/c when I switched to a standalone management (because it was problematic to have the EMS control the a/c).

Now that we have the AEM EMS + Boomslang harness option (running the EMS as a piggyback), I wish I could have done that.

interesting... what header have you got?

[pimp my yaris]

This is the manafold Cali Yaris is using. I have the same one on my car. It does clear the a/c lines with plenty of room.
