hey guys,

ok here is the story

my mate has a 2000 WRX... with all the usual mods... he is now in the market for a turbo

now keep in mind that this guy likes to cut corners... he will always go for 2nd hand/cheaper goods... so he is hooked on this idea...

and he keeps tellin me that with this turbo and a tune on his standard computer (dunno how good wrxy comps r) he shud b hitting somewhere around 350hp on all 4 wheels...

and since my GT3071R will be going in soon... considering how much i paid for it... im very intersted to see if a $700 ebay turbo will essentially give him the same type of power as my $3000 turbo...

http://cgi.ebay.com.au/93-07-GC8-GDA-GDB-W...id=p3286.c0.m14

now im a bit of a skeptic and like to check everything b4 i make a purchase... especially off ebay

but i dunno shit about those turbos and dunno anything about EJ20s so can any1 on here with knowledge on these two topics help me out..

1. Will this work?

2. I'd be expecting a shitload of lag.. what kind of driveability will this thing have?

3. Will it make 350hp? reliably?

4. Will it blow up into little pieces and f*k my mates engine?

thanks guys

I wouldn't put that on my lawnmower man.

There's a heap of threads covering cheap shit eBay turbos man.

My opinion is no, it's not worth skimping money at the risk of taking your entire engine out.

Well considering this is a skyline forum - its fairly unlikely.

Either way 350hp @ all 4, is 260awkw. There is no way known to man a 440hp turbo, is going to do that.

WRX is a fulltime 4WD, @ 300awkw you are making over 500hp

And you certainly cannot do it without full tune (aftermarket or chip), injectors and all the other usual supporting mods.

Tell your mate, who is clearly a muppet with no idea, to post his idea's and claims on a WRX forum and watch them laugh at him.

That is all we are going to do here because not even 1% of users of this forum own a WRX, but simply logic you cannot defy...

Pointless thread IMO.

i agree that i wont get much info on here but I trust the opinions on here more than on any other forum... which is why i posted

im just trying to get some real world examples of shitty ebay turbos ruining engines... even if they do not relate to a wrx...

but even just the 2 responses I have received so far which clearly point out that ebay turbos are rubbish should make him think twice

so cheers for that... :)

and on the whole standard computer thing...

I keep telling him that there is no way a standard computer tune will do the job properly...

but he said he went to MRC and the bloke over there said he could do a better job tuning the standard comp rather than working on an aftermarket computer...

dunno shit about WRX's so i cant really argue with him over them...

cheap turbo's belong on cheap nasty horrod drift cars. on cars where people dont build motors, just replace the bottom end after every round or 2 with another rb30e bottom end, which they can obtain for a cheap nasty corton of beer.

on a street car that serves as transport and is your pride and joy.... no no no.

the wrx whilst a great car is an expensive platform and needs $ to get good power from it

a skyline typical gtst can output 200rwkw no problems on standard turbo and piggyback, 12psi

thats because its an inline6 2.5 litre

the wrx is a 2.0, v4 cylinder engine so its smaller, less cylinders and it has a larger turbo

to get any power out of them you have to really wind the boost up on them

that td05-20g is tiny, its probably smaller the factory EJ20 turbocharger

the stock turbo is actually quite large for standard spec

WRX, EVO, SR20.. doen't change the basic laws that govern making horsepower. It's a 2L, 4 cyl.

Cheap turbo's are cheap for a reason.

They dont have the hours of testing behind them to prove how good their product is..

They dont test the turbo to see how or when it will fail and make the unit bullet proof.

Take Garrett, they stand by their product, openly state how many hours they have tested it for, and show some of the tests!

This goes for all other top brands (all the dear ones!).

Cutting corners on a turbo is just plain STUPID! Plain and simple. After he blows that junker up (and it WILL blow up!),

He needs a tow home, he has to buy yet another turbo, (and maybe another engine), clean the intercooler and pipes out, waste time doing all said work... Add all that up!

Thats a VERY expensive turbo by the time the car is going again.

Now about the actual power your wanting to make...? Do we need to go any further???

If he buys it and bolts it up it probably will make power, but it will also probably laggier that the equivalent sized turbo. Now in that saying that it will make power; it might make it more than once, it might even make it through the dyno session, he might even get 500km's on it, the the chances of him getting more than 12 months out of it are very slight.

Having owned WRX's for 5 years and spending close to 20g on mods, i can tell you a 2000 WRX with an unopened engine will not be reliable over 220kw ATW. The TD05-20g can indeed allow 260kw, BUT thats on a built motor running lots of timing and over 20psi boost. There is nothing wrong with the TD05 turbo's, they are proven reliable, and have seen some quick 1/4mile times, breaking into the 11's etc.

You do not have to buy a $4,000 name brand turbo to get a good turbo these days.

ok so ive checked the advert and i actually thought it was a trust td05-20g

but its an actual td05-20g equivalent turbocharger in size and looks

there are no tags, id plates or specifications/numbers on the covers, housings or components

it looks like a very cheap, ordinary typical ebay spec turbocharger

their warranty is 3 months and it cant be used for any illegal street racing

so im not sure how they would "validate" the illegal street racing

bolt it on and watch the shaft mangle itself

a sub $2k turbocharger is top of the range, highest spec not only in parts, components, well matched and suited

correctly spec'd wheels, trim and housing and not to mention the dump setup, intake snout etc

the bearings, oil fittings, and assembly are top notch and balanced correctly.

the unit will last's 100,000kms + and doesn't miss a beat - from a manufacturer who has been making turbochargers for trucks and cars since 1936

but here's this no brander spec turbocharger for $700 and people expect the world from sub $500+ ebay turbochargers

for that WRX guy the standard turbo on his car is probably better spec than this ebay one

thats pretty comon these days, a lot of skyline guys find cheap ebay turbos for $500 and they are pathetic

the standard hitachi unit is better and more reliable. i mean my hitachi turbocharger is 213,000km old and still flies with 12psi up it

if you want to fit a new turbocharger to your car, budget $2k for the turbocharger

its like buying a new plasma tv or LCD tv

sure you can buy a new unit for $600 under some ching chong brand

but no one does, they are junkers, poor warranty, poor basic units

everyone goes for the nice flashy $2500 pioneer, sony etc as they are a good well known brand

well known parts, reputable warranty, they can go back to their local jb hifi and get help etc

what on earth - its frustrating and heartbreaking when guys buy these junker turbochargers, expect a reliable setup

and to make more power and less lag only to have it mangle everything, not to mention nothing mates up during install

EJ20's don't really like biggish turbos , TD05's aren't huge but enough to make ram raider lose its bottom end .

From memory the 20G compressor is ~ 68mm OD in a largish trim , your GT3071R's compressor is 71mm 56T and in a reasonably substantial T04E comp cover .

I don't remember the TD05H turbines dimensions , I always thought they were a little agricultural anyway .

The real cats whisker (OEM) on a street driven ant eater isn't a TD05 at all , it's the rare JDM TD04HL-15T . Every cap on backwards drain pipe thief thinks all TD04's are rubbish . The "HL" version of the TD04 turbine is hardly small and they work quite well for a street car . If you really like Rex's pull out all the stops and use the factory twin scroll gear - it works .

350 at the claws with a 20G based turbo , and a copy of one as well ? Rehab time ...

thanks guys... this is exactly the kind of info i was after...

hopefully this will stop him from puttin this rubbish on his car...

its not a bad looking car so far... id hate to see it fall apart

    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
