eBay knockoff GT35R testing.

[JusMX141]

We had three possibilities....have the flange machined on the cast mani, use the SFP manifold (if it works), or use an adapter plate on the stock manifold (Mitsu manifold to T3 turbine housing adapter).

He brought the turbo, and we used my AWD as a test subject; the SFP tubular manifold ended up working perfectly. It fits as if it was made to have a GT35R strapped to it!

Another awesome discovery is that the stock coolant line banjo bolts fit right into the GT35R's CHRA, so running water lines will be quite simple.

Still not sure at this point what I'm gonna do with the cast manifold....possibly keep it and have it machined, possibly sell it. It's built so well I really hate to part with it. There's no doubt it would work the way it is on a turbo with a small a/r exhaust housing (possibly some variation of a GT30R, or many of the T3/T4 Hybrids with relatively small turbine housings), but the angle's just off a little for the 35R.

Do you have any pics???

 

[JusMX141]

Nothing yet....the car it's going on is in MD, I'm about an hour and a half away in PA.

In a week or so, I'll take alot of pics of the completed project because we're aiming to have it done for the DSM Shootout....he's driving the car up.

To some of us, trying different things is the entire fun of modding a car, and going the cheap route makes it even more interesting. Any idiot can buy baller stuff with a credit card from a vendor and go fast, but what's the fun in that?

[/rant]

Yea I would'nt call someone like John Sheppard or Brent Rau a Idiot for using the best stuff money can buy! IN fact there Twice as smart as the idiot that thinks they can do what they do with Cheap parts....

Going the CHEAP rout makes you cheap! thats it, Getting the best bang for your buck is the smart way to build... IF you can only afford a 400 dollar turbo dont GO buy the Knock off version of a 900 turbo that sells for 400 Off Ebay, buy a good turbo that runs 400 bucks with proven performance and Reliability....
OR do what you do cause what I am gonna say is just like I will always BUY better Quality and LOVE doing so.....

 

[KPEclipse]

to each his own, but you cant knock anyone for having bought a cheaper turbo, getting great performance out of it, and paying half, and sometimes a quarter of what someone else does.

How can you go wrong - if you get a 900 dollar turbo for 400 bucks, and it works even a SMIDGE less than the 900 dollar one, looks to me like you made a great investment.

also, i dont think the dyno, or the track discriminates because of the origin of your parts. if you can build an 11second car out of chinese parts, and it works just as well as an 11 second car out of all name brand (Greddy, Injen, FP, so on and so forth) why not? You'd rather pay more to say I have a FP(insert turbo here) then just having the same turbo do the same thing for less price...I don't get it.

as B said
[/rant] hahaha

Who's buying Shep & Rau's upgraded parts? Probably the performance shops that want their name all over their cars....if not, YOU'RE buying Shep's parts with every transmission you buy from him.

He's earned the right to buy what he wants to run. I'm sure he started out with nothing just like the rest of us. It's not like either one of these guys were handed a car and a sponsorship the second they began driving.

 

[nfernotalon]

Any news?

You're going to compare shep and rau to the average guy modding a 15 year old 5000 dollar dsm? Experiments are fun. This is one. You do your hobby the way you want, we will do it our way. If you don't like modding cars like this, click out of the thread. I see there's some great threads in the vendor section for your reading.

It would be almost tempting to buy for me. But, I'm not sure of what the quality would be. I would definitely be afraid of the guts of it coming apart and destroying the engine. But, you never know.

I've only ever seen these knock off turbos fail. I had a friend who purchased one, it failed in a couple months so he went and purchased another one, it never did boost right at all. It was a failure from day one.

You are never saving money with these things, you are only going to spend more in the long run, half the cost of the real thing messing up and then 100% the cost of the real thing doing it right in the long run spending 50% more than you should have.

To each their own though, Quality isnt cheap and cheap isnt quality.

Well thats the thing cause I have seen alot of ebay 16gs around here on our local forum hold up fine. Granted these guys are not going to boost over 20psi. I am interested to see how this turns out. I have bought some ebay parts before and they work fine, never had the balls to buy a turbo though.

Its not just the turbos, I have seen BoV's that leak on day 1, I have sen waste gates that dont close. I refuse to risk my car to save a few bucks.

 

[rrussell]

This is weird because in my area 80% of the turbos that are being used are Ebay's without any problems. I would also guess about 90% run ebay waste-gates and BOV's with no issues.

It started out with the younger generation kids still in high school that can't afford real name turbos. Now so many have had great luck in the last four years that's all they buy.

I have personally tuned 6 cars this year that are running the eslave turbo's. I even went so far to let them know that the turbos won't last. They said they don't care they will just buy another one for around $200.00 if it fails. But all 6 are still running great without any issues.

I can't believe how many Honda's in my area are turboed.

 

[dsm-onster]

My wastegate doesn't leak up to 30psi with my Holset. Unless the diaphragm is split, it can't. Now it does come with a 5psi spring. But have you seen how easy they are to make? It doesn't take a quality factory to build a wastegate that will work like a TiAL. IF it does fail, guess what??? I can buy all the guts of a TiAL from TiAL and that plus the original ebay gate is still about HALF the price .

Regardless, the interesting thing is being able to determine HOW these gt35R turbos fail. If this one does fail and it is because of a lack of balance, then how much is it worth it to you to get an ebay turbo for $300 and have it balanced for another $90 to have an otherwise perfect replica in aerodynamics to a gt35R? This is why this thread is interesting to me . See, then it wouldn't be an "ebay turbo" any more, would it. If the chinese sweatshops are too cheap to balance them and that is the only difference in performance, then I'll take on that responsibility to pay less than 1/3 the total cost of a $1500 turbo. The real results will be to determine why it would fail, remedy the issue, and then see how it stacks up against a garrett.

 

[JusMX141]

Monster, I always enjoy reading your posts. So realistic for true DSMer's, always informative....

 

[Stapl3]

Did you want to ask him out on a date or something?

 

[dsm-onster]

What will be informative are the results of this little test .

 

[Blindsey]

Well coming from personal experience. I have ran an Ebay Evo 3 for about 8 months then sold it to a buddy. He still runs it to this day with no problems.(22lbs of boost) I also run an "Ebay" wastegate with no problems. I think people really need to quit judging from others experience and judge from their own. Even if I have to buy an Ebay GT35r every 6 months it is still less then buying a real one. So judge for yourself. Put your money where your mouth is or STFU

 

[JOEY A]

"Less" doesn't mean "imprecise". I'd sure hate to gamble on a $1200-$1500 piece of equipment just because someone said that the amount and volume of oil should be LESS, and not know how much the pressure precisely needs to be..

Your posting BS please knock it off so pther people dont get the wrong idea

 

[rrussell]

Is this the same place you got your turbo from?

eBay Motors: New GT35R Spec Turbo 56 trim 0.70 AR - 84 trim turbine (item 150284048876 end time Aug-21-08 12:12:11 PDT)

 

[JusMX141]

That's NOT where this turbo came from. The one in that listing is a journal-bearing turbo; the one we bought is ball-bearing.



The testing is underway....the turbo's on the car. The car wasn't done in time to make it to the Shootout, but as soon as we returned home he resumed working on it and finished it.

The car is untuned for the current setup, but he's still seeing full spool around 4500rpms. Full 4" intake pipe, GM Blow-thru 3" MAS. Boost is currently set at 20psi which is far below where he wants to be, but being that the engine is currently stock with only a head gasket and studs we're keeping it conservative until winter when the engine gets fully built.

So far, this has been quite the budget build. The whole project (turbo, used SFP manifold, Tial 38mm flange, Garrett 4-bolt downpipe flange, inline oil filter, some misc. hardware) has cost less than $650.

Now the question is how long will this bad boy last? Hopefully these turn out to be halfway decent.

 

[caliboy23]

He's seeing full spool by 4500 RPM on the stock bottom end? Thats better than I thought? I already decided on the SBR G60 which is why I baught a mitsu flanged tubular manifold. But If this turbo turns out to be as good as it could be, I may have to scrub the idea of the G60 and go with this thing.

Hell, Im see full boost(28psi pump gas) with my pte 60-1 at 45-4600 in 3rd gear on my stock bottom end. Im sure, with some tuning, he should see 24+psi at 4200rpm with the bb 35r.

To the op, If the engine isnt on its last leg, you should be able to up the boost to 25psi with proper tuning and supporting mods. The stock engine will hold it just fine if healthy enough. At 20psi, your not even in the efficiency range or the 35r. The tune is the major part. Without a good tune, it will break just as quick at 15psi as it will at 25psi.

 

[dsm-onster]

Yea, if he's flowing 40lb/min at 20psi then he is right at 80* efficiency at peak which we're all sure he's not. He's likely running 35-38lb/min and thus in the 74% range at 2.3PR.

Is there any surge? 4500 rpms is well within the spool range of a gt35r. Nice! I forget, did you measure the wheels?
