Corksport turbo review

[hitANDrun21]

Alright guys I was beta tester number 01, im going to start off by saying I was lucky to become a beta tester because I originally was not going to be one, but apparently one of the other testers had something come up and returned the turbo, thus I was called upon to fulfill his spot, so I was last to receive the turbo but still ended up with turbo number 01.

I would like to note I found it very nice that the turbo comes along with everything needed to do the install. A new DP gasket, exhaust mani gasket, new studs, nuts, a coolant line, and a new heat shield, all boxed up nicely and protected as to not be damaged during shipping.

Lets get into this now, I have never done a turbo swap, but I have done just about all other the basic things other than building a block so I knew what I was getting myself into and started on a Friday in case I ran into problems and needed the weekend to finish. The install went pretty smooth by the end of Friday afternoon the old turbo was out and the new turbo was in but had to call it a night and come back the next day to put on the intake, battery, 3 port ebcs then fire her up.

I ran into some tuning problems (tuned by Nishan), non turbo related, I had my 3 port ebcs fail on me and had to get a new one so that set back along with being last of the beta testers to receive the turbo has made it so I am not actually finished with the tuning yet, I am mid way through my 91 tune (I live in California and we have shitty gas) so currently Im making about 315hp @ 20psi. I will be doing an E85 tune so I will post up the results from that as soon as it is finished.

I drive a lot so I have put over 1000 miles on the turbo already in the short time it has been installed it has put up with the abuse I put it through very well, I also Autocross my car and have an event this weekend i will be running the car in so I will post results of how it performs on the track as well so stand by for that.

Overall I could not be more pleased with this turbo and its performance. It surpasses my needs and what I ever wanted power wise for my car. The turbo is made vey well, and looks very nice, it is a really responsive turbo and flows better than the BNR, its a shame to have it tucked away in the back hiding from us all.

Can't wait for the e85 results. Good luck!

Oh brother, first some clown named "Raider" now this....

"the turbo spools very smoothly and is of course pretty audible"

"from 3K to to 5700 or so in 4th feels a LOT quicker than it was on OEM"

"the turbo looks very nice, it is a really responsive turbo and flows better than the BNR"

Did you guys pay someone from mazdas247 to ghost write this shit???

-----> post data logs or gtfo.

[Raider]

Bunny, be nice.

And logs from me when done, ok fancypants?

Eh, you both look alike to me.

Logs will come, but no point until we are done and can really compare. OP and I are both in the same boat.

Send me some topless pics of yourself and we will call it water under the bridge.

[hitANDrun21]

I will gladly post data logs when my tune is finished for you.

[speedboost]

can you post your mods please - put a sig

[dale_gribble]

I really wish they would have reached out to me, we could have done some work. Graph and chart porn for days vs. k04 and bnrs3. I have hundreds of runs for baselines of many combinations of mods/intakes/intercoolers/exhausts/etc across many temperatures and gas/wmi ready for easy 1:1 comparison on my car as well as the capability to self tune.

I know others do as well, so I am not suggesting I am the only one, but I hope one of these fell into the hands of a data/tuning guy.

*sighs*

[hitANDrun21]

sorry forgot to put the mods...

power mods mods I have :Corksport 3 inch intake, Corksport catless dp, Corksport race pipe(stock cbe), CPE tmic

[sheston]

Did you have an BNR3 before this? Comparison logs would be great

[hitANDrun21]

I did not have a bnr before this, when I say it flows more than the bnr im going off what nishan has told me.

[jdmage_mx5]

Let's get this show on the road! @Raider; where can I have a 3 port EBCS shipped to so we can fix your issue and see some true comparisons?

Not sure if serious or not. I'm not looking for a handout (or to derail this thread) so pm me.

Pm sent. Sorry OP for thread derail.

Thanks for posting. I looked at the listing for this turbo yesterday when it went up and there's a lot to like about it, from the fact that it includes all new hardware including the turbo studs, the billet compressor wheel, and many other things about it that seem very well thought out. I'm eagerly awaiting some real pump gas results from these turbos. Their website says it's capable of flowing 50 lbs/min at sea level, which is about 380 g/s. I want to see a log that supports this claim from someone. If that's true, even if you can get close, that's an incredible amount of airflow for a turbo of this size.

[Raider]

back on track.
@hitANDrun21; I went ahead and posted my before run, and then one after, noting in the Vdyno shot, that it is a work in progress. Would you be willing to throw a couple logs, 1 before, and the most recent? I think it would help a lot.

[ms3blackmica]

Thus far, the turbo has impressed me.

No issues tuning it as far as boost control goes and I have seen power come fairly easily.

Hoping to work with someone with auxiliary fueling to really test the limits.

Also, for the record, my statement that it flowed a bit more than S3 is only my findings at the current boost levels. I have not exceeded 22 PSI yet with anyone.

[hitANDrun21]

for those of you interested in seeing a data log, please note this is an unfinished tune but it is my most recent map from nishan on 91 octane.

Thanks for posting this, It is always nice to see some data and numbers. Helps us do the best we can.

[hitANDrun21]

and here is my finished tune data log from the ko4 if youd like to compare the two.

[hitANDrun21]

ko4 tune on the blue graph, unfinnshed cs turbo 91 tune on the red graph.

I don't know why but my v dyno numbers have always been low but ive continued to log in the same spot so I can keep my baseline and this does show the hp gain so far. I could care less what vdyno says my actual hp is because I know its wrong. im posting these graphs simply to show the gain in power along with the data logs posted above.

Hi I have a question.

I just ordered a corksport turbo and was wondering if you need to have an aftermarket boost controller (such as the cobb 3 port) to run it at say 300-380hp? I was under the impression it was just a simple bolt on and tune. I get my tunes via dyno (mazedit) and loaded onto my accessport. Is the boost control 100% essential for these levels?

Thank you.

The stock EBCS is fine assuming you run the provided restrictor. You have to know how to tune though. You can't bolt it up and just run it. At the very least you will need to zero out WGDC, get the spring pressure curve baseline, rebuild boost curve with WGDC/dynamics, setup boost tables, do a MAF cal, etc. If you don't have upgraded fuel internals, you better get some on order.

I am taking it to my tuner who has a dyno and specialise in Mazdaspeed (MPS here in au). I have cobb stage 3 components already in and custom tuned. Asked my tuner since and it is good to go. Thanks

what is this shit? No pictures? All the CS reviews have no pictures.

[hitANDrun21]

will pictures make you feel better?? haha

Sexy af. I like the side-by-side pic, you can see the size difference. (insert dick joke) (insert insertion joke)

Is corksport actually manufacturing this turbo, or is it just a glorified re-badged "something or other?"

CorkSport is too small of an operation to manufacture their own turbos. It is built to their specs by someone else, though it has not been confirmed by whom. @dale_gribble has done his research (hats off btw), and speculated it to be Tomioka.

Per Corksports website it's a "Mitsubishi TD05H-18G"

This is already widely-known. Tomioka makes a lot of turbos using Mitsubishi parts.

There no call for that kind of harshness. He provided relevant, if old, material, and did so in the spirit of improving the discussion by adding factual information. As newb posts go, it wasn't terrible.

[Thepedigree13]

Love the infamous side by side pic.

It is actually alot bigger than I thought.........first time I have said/heard that.......ever.

[MD1032]

How does the spool time feel on these cars, reviewers, compared to the S3 and K04?

[865ms3]

I wish one of the beta testers would have be willing to push this to the limit and provide data... (i know beating a dead horse)

Not that I'm going to buy one with a 3071 now and a 5858 being stuffed in soon. But I'm always being asked "what turbo"
