Spend 10 minutes reading through their feedback which is 90% positive *including RX7 owners that purchased the kit*

Im not interested in this kit..but I figured it's a good find for discussion.

Looks like the kit is made up of ebay components...especially the wastegate (HKS style).

Not knocking it, but I would be wary.

It is junk. I know the guy selling them, he went to china, just bought everything he saw and came back here trying to offload it.

China is a very very very sensitive place, you buy from the wrong factory and your screwed. And 95% of the junk he bought was crap.

Stay clear.
Buy from a reputable company that will provide you with a warranty on any products they sell or manufacture and look at customer experiences for how good the product is.

^^^^ See there you go. Another reputable vendor from the area reporting on it.
yea.. ebay wastegate which could fail leading to boost creep...cheap manifold that'll crack (even though alot of people are running ebay manifolds).....and off the shore made turbo. seems like its on a mission for failure...but with so many kits sold. Im wondering who's hiding on the forum and ran this...or IS running this...yikes.

Watch out people.

Totally. I already ordered 3....by the third kit it has to work. *1 week later* Guess not.

It amazes me why people keep buying this junk and then get pissed when they find out its junk. Its not rocket science people. YOU GET WHAT YOU PAY FOR! If you can't afford to do it right, then don't do it at all.

^^What he said. My ASpec 500R turbo kit has been bulletproof and troublefree the last 2 years, ran it up to 19psi so far (and 26psi once by accident ). Plus, having Sean available for product support is worth a lot in my book......

I've said it before, but the China stuff really is a crap shoot. There are people who do get lucky. I've seen an ebay turbo kit work pretty well (at 7psi) on a civic. The manifold and turbo have held up a couple thousand miles so far at least. The wastegate was blown from the factory--it might as well have been one gaping hole spewing out exhaust and I am positive it was installed correctly. It was replaced with a real Tial and worked perfectly. The gaskets were complete garbage though, that's one thing I've noticed about any ebay turbo stuff.

People who install those parts on their cars deserve what they get in my honest opinion......

Ottoman

in my area there are alot of ppl running Chinese/Thai duplicates of T-78 turbo's

(it's even copied down to the greddy logo and everything)

the turbo is approx 1/3 the price of the orig. and MUCH more readily available

at the drag ppl have boosted them past 30psi.. and have taken them into the 9's..

if and when the turbo's do fail.. they usually blow smoke due to the oil seals...

but I've never seen turbo failure destroy the motor.. I have seen these "cheap turbos" grenade motors from excess boost


1 thing I must note.. is that it seems their effeciency range is in the upper boost range.. which I guess would mimick the real T-78 as well... but I dunno..
If i see one around.. maybe I'll go take some pics of it for side by side comparison with the real thing...the compressor side blade differences are noticeable..


they also run alot of 2J 1J and RB series manifolds also from thai/chinese origin..

sometimes the bolt holes don't match up perfectly and require slight Ovaling on 1 or 2 of them... but very minor..

after buying it they take the manifold to the machinist who will face the flanges for dirt cheap..

fix a bolt hole or 2 when necc.. mount them on the car and forget about it..


I haven't heard of one cracking on them in years... (that was in the old days)


and this is on cars with 6 skinny runners and collecting together and stuff..

I think our beefier 2 runner design is probably even less prone to cracking...

just be proactive and brace it as well..

i think the whole get what you pay for garbage is getting old.


IT IS NOT THE REASON YOU DONT BUY EBAY PRODUCTS OR CHINA PRODUCTS for that matter.

People are thinking the wrong way, their is nothing wrong with competitive pricing, as long as the vendor is willing to stand by his products, test the products properly before putting them on the market.

My fuel pumps went into countless cars of my own(friends etc) for 2-3 years before i started selling them.
The twinplate clutches i had made, were finished manufacturing in the end of 2007.
I put 6 of them in close friends/customer cars and my own and didnt put them for sale till only a month or so ago.
ANd even then, this is not enough and further testing will only come with time. BUT most of the guys on ebay are out their to make a quick buck, dont know anything about the product their selling.
Some of the cars i have been tuning for years, have had alot of different products on them, and i have the luxury of being able to test my own products on these cars, and be able to compare my product to other companies and know that my product is better then others.

This is what people should look for in a vendor, someone who has a REAL warranty, not one that looks for excuses, a vendor who supports your product all the way till its on the car, and then all the way till its no longer needed, even if warranty is over.

Unfortunately even companies such as garrett and turbosmart dont have this anymore, but their are still good companies out their.
Shoppers must be smart and look for a good deal, and look for the support, in most cases the support is worth more then the product!.

well you can count out HKS, Greddy, and Apex'i for the most part (at least here in the States) because they have very small offices that are understaffed and unresponsive (although they do eventually honor warranties), plus often most of the materials they have on their products aren't in English (HKS is the worst with that. They don't even bother to translate anything). It's hard to find good service these days. And this is further compounded by the fact that you have to go to internet distributors most of the time to get their stuff.

Even the larger English-speaking manufacturers have **** service. I had one of those POS AEM widebands a few years ago and their tech support dicked me. I sent them the gauge and they literally just sent it back to me still broken. No explanation or nothing, and the guy on the tech support line refused to admit that they didn't do anything with it. I had to intervene with the customer service department.

It seems the only guys giving good support for their stuff are the medium-small vendors like A-spec, Corksport, Hondata, and Cobb tuning. And that's just another reason why people are turning away from the big Japanese manufacturer's and go with ebay ****. It's a similar buying experience, just worse quality.

I had a similar situation with AEM. With their stupid plug and play ecu, spent like 3 days on the phone with tech, cause the car wouldn't start with it in. Finally had me send it back and they said something was messed up in it, send me the same one back supposedly fixed and it still was still messed up. I told them I didnt want the POS and the place that I ordered it from, best they did was give me store credit. So yeah lots of places have poor customer service if they give you a crap part.

Regarding that turbo kit, It could be pieced together cheaper then that. It's not even complete, it has the 3 main parts. Manifold, turbo, and wastegate. The turbo is kinda small and won't be making 450 hp. To4b's can be found pretty inexpensive. Plus that turbo looks to be a knockoff. (could be rebuilt for another $200 when the oil seals go. The manifold looks like the OBX/ SSautochrome, which is fine. I personally have been running one for about a year with no issues. The wastegate is probably the HKS knockoff, I think it's probably ok, but if the car is to be tracked I might be weary. I've seen several people run them without issue on the street/dyno. I've also seen many name brand wastegates leak cause they didnt seal right, so that's whatever.

Now what's wrong with the kit... its missing everything else. And that adds up in a hurry. Oil return and feed lines, oil return/feed flanges to mount the lines, no oil restrictor, downpipe, air filter, and the turbo has no v-band flange mounted so you will need to buy one and weld it on, no v-band clamps for the downpipe connection (once you make a downpipe)

The exact kit shown could be pieced together for $400-500 using the same parts pictured.

I messaged 2 of the buyers from ebay that ordered the kit. So far only one responded.

"Dear unityoi,

So far so good! Im boosting at 12 psi on this kit and im beatin sti and evos all day! Dont buy this until you have a Power FC fuel management! My stock ecu took a **** after doing the single turbo and vacuum bypass... if you wanna see how it got installed and finished, check out fullarsenalmotorsports.com and regeister. then go to forums, whats going on on in the shop, and FD turbo install. I would say this kit is definately worth the money i havent had the car dyno'd yet but ill let you know when i do! any other questions, let me know

- jdmrex101"

if the second guy responds. I'll follow up.

Stay away from that turbo and wastegate as both are knockoffs. The manifold is ok but I know some will argue that. We have never had an issue with those manifolds.

My opinion is the most important parts to a kit are the turbo and wastegate. You can replace that manifold for a couple hundred bucks.

By the looks of it that kit doesnt come with a downpipe so expect a few hundered bucks to have a shop make one.

that looks like the size of bnr twin but with only one turbo.


If i remember correctly someone was the guinea pig for the master power t70 and it took him 22psi just to make 400hp. SAD!!!!!!!!!!

The last things I found searching. I've already decided on going with the RX7 T04S kit or GT35R. This is again to help people as a deterrent or a WARNING. So the average person doesnt stumble upon it and ends up in trouble. Despite this one guys claim of it working out for him.

Here's pics from his install:


















He said he had the kit on since this past October

I have several customers of my own that have bought these kits(from this seller) and have had to have their flanges resurfaced 3-4 times now and they have had the manifold it self crack. Manifold pipe is only 1.6mm thick.

it is designed incorrectly straight off the bat.

better a used genuine part than a new knock off, unless you are part of the lucky 10% that never has problems
