PAY cheap pay twice
 

Like that Cat of yours , its always again and again a leap of faith !! :lol1:

hahaha, he'll make it one day :D

maybe :lol1::lol1::lol1:

started some remote mapping this week, first revision tune loaded on, seems nice smooth power delivery so far, turbo seems a bit laggy compared to my vf36, im sure some work on the AVCS tables etc will make it more responsive low down

Keep us up to date with your progress really interested in your twin scroll results.

me too, i hope i can get it mapped nicely and it makes decent power and is good for a daily driver street car

Any updates Dan?

Not much, havent had a chance to do some proper logs and the lack of boost on the new map was annoying i thought my knock detector was broken so i loaded back on the old map and as soon as you go on full boost the knock detector lights up so its working fine, just no knock in the new map which is good. I need to try get some logs in and send them off to mapper before i head off on holiday for 3 weeks on Thursday!

So, massive thread revival but how did everyone get on with their Kinugawa Turbo's??

Any graphs?

All still running well, none blown up?

the lack of graphs gives it away ;)

Two threads both over 8 pages and nothing to tell................Says it all really.

There's graphs on the first page...

My Turbo was a 16G PRC copy, using a Kinguwa actuator ( as the standard one was starting open far to early ), that performs fine, however I still need to get over to UK do a remap with Duncan, I just don't seem find the time; so while the car runs fine, but Im still not getting the best out of it, doing a RR here makes no sense till Im at Surrey RR and have the final map.

cheap turbo and **** mapper, thats gonna go well haha

Tidgy, 23k since build on JGM , whom saddly cannot finish the job.

:poke: try to be hopeful and positive in life.
with a leap of faith just like your cat.

With so little info on these it's hard to take a leap of faith.

Like to hear from people who have covered decent mileage too 10k/20k plus

Surprised at how little info there is out there on these,

Lucky if i can find 2 graphs,

Compared to the amount of threads on these,


If it makes good power spools well and takes the miles it's a no brainer,

But i havn't seen anything to prove this.

That's fair comment ,
& while mine is not a Kinguwa turbo, its a PRC cheapy 16G, Tidgy loves it!
So Im never going to be able to help you with a curve. What I can say is the standard of engineering and material on the Kinguwa waste gate acuator is first class. The interchangable springs with different ratings allow you to really tune in when the gate opens. I suspect most people whom are tight on budget , that buy cheap turbos don't care much about spending money for RR afterwards. The Kinguwa is however not cheap its mid priced, this video gives you some idea what you are dealing with ( the actuator here is however a "bought in cheapy" this is not the configurable one I bought separately) The ability for a turbo to spool to a choosen pressure is limited by WGA's tune and machine tolerances , it follows that if the impeller vanes do not pass neatly to the inlet then you will not build boost quickly. Also if the bearings slop around then the whole assy won't last long. Other than this a turbo is a fairly simple bit of kit, and you should not read to much pathos into reputable but over priced " brandnames". I can only "generalise" to say from experience of import of parts and sourcing in manufacting of SMT machines , the company in which I work build in USA and PRC that what comes out of Taiwan can be better trusted than PRC. However as soon as I say that 10 people will spring out of the bush on this site and contradict me. If I had the choice and the money to pay for them I would only use parts made in Germany. ( Then of course I would because I live here ). It would follow therefore that If I had just spent 5 k to put a decent re-built engine in, I would not put a 250 quid turbo on top. In my case I spent in total 1600 quid doing that and 600 tune from Simon to arrive at somewhere between 320-330 bhp , Im probably missing 15 bhp as Im not yet running 1.45 bar as planned. You have to decide what you wish to spend and live with the consequences. Best regs Ralph

the biggest issue i have with them is they are very unreliable as far as results go. Some do decent spool and power, the majority just don't. Which is exactly what your saying.

The more expensive turbos, garret, blouch etc are made to tight tolerances so you get a consistent result. That's why you pay more money for them in the first place.

Not to mention the cheapy's are just copy's, not always for the better.

I couldn't find any "Real" results to prove them unreliable either,

Mostly folk saying "I've heard", "My mate told me",

Precision Turbo had a bad name years ago and now they are one of the best in the market,

I think you would be surprised how little the garrett/blouch cost to produce as well,

I agree on the unbranded crap £100 chinese ebay jobs, only going to cause trouble

But Kinugawa/Arashi are actually quite big globally.


I didnt personally take the risk but seriously considered it,

I was going through my subscribed posts and clearing them out. reading through this one , the discussion members were gasping for some results on a cheap TD05 16G (mine was a $200 via CRX racing)
though I was prodding Tidgy and his cat to consider a leap of faith though it pains me I have to say this , his comment about consistency to build good power is in part justified with just a 311bhp at SRR
& Duncan pulling the strings. .

In a direct comparison, I fitted a SC36 and this made 320lb/ft @ 4500 and 328bhp.
https://cimg3.ibsrv.net/gimg/www.sco...bd0e9e38c6.jpg

I should note on the 311 bhp the fuel used was Aral 102 and on the later SC36 result the fuel used was Momentum 99
the housings are both 7cm , the main difference in these turbos is therefore the Blouch billet wheel on the SC36.
both are sleeve bearing turbos.

So what needs to said here is I had around 25 thousand miles out of a PRC turbo that
cost less than £200 , the reason I changed the turbo was due to the shaft play, the vanes were starting to whine on the
inlet housing wall. you therefore have to decide if the extra £800 for the SC36 is worthwhile for 5% more power and "perhaps" reliability.

I regret not knowing at time of purchase from Scooby clinic (selling what was on the shelf which is just business )
that the SC36 was available from Blouch with a ball race bearing. I would personally would have paid more for that for peace of mind.

Don't write off the Kinguwa Turbo's however these are from Taiwan not PRC , I would expect these to be better engineered
and better quality controlled / balanced. So if anyone is still able to give Dyno result graphs and longevity experience on these
then this would still be helpful.

Who the mapper prob dont help either,,, lol

Linksfahrer, aren’t those graphs remarkably similar up and to the torque hump?

both the prc and sc36 seem to make almost identical torque at any point up until about 4500rpm, at which point the prc doesn’t seem to perform as well anymore, meaning you don’t get the hp of the sc36.

:thumb:Good spot , That extra bhp came later (343bhp) when I asked Martyn to go at it again after the headers were ported , on the graph above boost / timing is deliberately tailed off at 5700rpm .
There is no point trying to blow very hard through a rough hole. The 328bhp graph is only helpful as the only physical change at this point was the addition of the SC36.

The other difference being the fuel , and of course the mapper. You will notice the PRC TD05 begins by 4000 rpm to struggle versus the SC36 .
The jury will have to stay out as to why the TD05 power stalls a full 500 rpm earlier on Aral 102 when you might have expected it to go further with some more timing advance.

Leaving others to debate the philosophy of building power with timing rather than just blowing as hard as your turbo can. :wonder:

However I am sure you would agree the combination of the SC36 / ET tune gave overall a better result. ;)

Its a pity I can't find out how much more could be achieved with Aral 102
Plymouth is so much further than Farnborough is from Germany, so even the trick to fill 2 x 20 ltr into the car at Dunkirk won't help
as its all gone again before I reach Exeter, Nor can I take more cans as I nearly always get stopped for a boot search prior to boarding.
