Very nice indeed!  Here are some pics of my old baby from back in the day when I had plenty of disposable income (pre-kids).  Running around 500bhp.  Bored to 2.3l, IHI RX6 turbo running 2.0 bar, forged internals, FMIC, JUN suspension, and so much other stuff I can't even remember now - fuel system (pumps and injectors), headers and exhaust, ECU, launch control, intakes and filters, Cusco dual plate clutch, Cusco LSD....

Memories.  Damn I miss that car.  I think it was about 12 years ago I finally had to get rid of it.

Gorgeous car, could sell a ton nowadays, especially with that sweet dual plate & cusco

Any fuel from 87 octane all the way up to 95 octane, benzine or "so-hol", would run ok in a modern fuel injected engine because the engines have knock sensors and electronic timing advance. They are designed to advance timing as much as possible/get better mileage and if a really low fuel were used it would automatically sense a knock and retard timing. 

 

For most modern engines, it is very unlikely for a person (let along the ECU) to tell any difference between 91-95 octane, benzine or "so-hol", unless your vehicle specifically requires it (High compression engines)

 

V-power is a gimmick to try and get you to buy Shell fuel over the competitors. Buying it means their advertising worked on you. 

 

"So-hol" fuel is 10% alcohol and 90% gasoline, and again, just about anything will run fine on that as long as its not left in the tank for an extremely long period of time (weeks if tank almost empty to months if tank full) or using a carb. 

 

One thing ive seen in here is people using E20 in their engines and I wonder if their vehicle manufacturer specifically states that they can use that fuel? I would hope nobody puts E20 in an engine that isnt specifically designed for it. 

 

General rule of thumb is you can go higher in octane ratings over what your manufacturer requires but never go lower in octane rating.

I use E20 in a very old car, people have tested stock plumbing & injectors could sustain 30-40% ethanol, but that would destroy stock fuel filter. 10-20% no problem at all.

Last year been refurbishing my tank it's all shiny inside, outside also OK, fuel pump works prime. My car frequently sit on jack several months with half tank E20 sometimes mixed with leaded...

I thought 91 was to leave the forecourts a while ago but it kept being sold so I continued buying it. Once it disappears I'll most likely use the standard 95. E20 just never gave me any power when I needed it. I wouldn't say I'm a boy racer but people drive very aggressively in my area so even for city driving I need something under the right foot.

 

I prefer to use Bangchak as my local is self service. I don't like sitting in the car with no Aircon (engine switched off)

Doubt E20 would negatively impact power output, unless dyno prooved.

Unlike E85, whether closed loop or wot, E20 have very little difference than Gasohol 95 in terms of power density and AFR, if not for better (slightly leaner would increase power for most cars, until you can't hit certain AFR in 90%++ duty cycle). Also E20 is said have at least (if not better) same 95RON as Gasohol 95. And Gasohol 95 itself is E10, too. 

Alas Thailand fuel grades are just s*lly. 91 RON is only 87 AKI if in states, and even worse almost no much cheaper than 95. Should be phased out ages ago. And should introduce RON100 pump gas like in Malaysia! ????

Doubt V-Power would be much better as it's still gasohol and 95 RON, guess maybe someless ethanol contets or some additives for GDI engine, but that's it. 

Malaysian 98 V-Power would be great though, too bad in Thailand fuels capped at 95. 

E20 has been advertised (at least by PTT) having 98-99 RON, could be used by most cars without big modding, would be best pump gas except E85.

Got my CHRA balanced. What I learned many rebuilders only provide balancing service for turbos rebuilt by themselves, very grateful @Turbodynamic for make an exception! 

0.05gmm static with no couple unbalance = 5.5N @ 100000 rpm, or 0.56kg force( 0.05g/0.001m*(100000/60*0.001m*2pi)^2 ). Totally within bearing spec and makes me very happy. My hand assembled was 0.21gmm static / 0.21gmm couple, about 8 milligram per inch, not too bad eh???? but may make mess at 100k 555

Also: don't forget bring your comp housing if do balancing. I only brought in CHRA at first and told comp housing is needed for high rpm balancing. Cost me 800baht more in taxi darn. ( I think comp housing usually not needed for balancing? Perhaps they just want to test with housing on to rule out badly rebuilt turbo with bad clearance )

I have traveled to China many times. I have friends who have been deported. They were lucky that they didn't disappear. China has a mission to take over the world. Don't think they will stop with Hong Kong and Taiwan. But keep smoking that stuff you're on.

There is a lot of fake news everywhere, but at least it can be called out in the west. Not so much China.

"China has a mission to take over the world. " input smearing & sacred propaganda here plz.

Wow. Someone really believe that. What China love is make money, and they know they can only excel in peaceful competition, them military spending though large is quite miniscule compares to #1 firearms exporter in the world, who wastes trillion of tax for nuclear carrier, nuclear arsenal, stealth fighter, etc.( And actually shooting people all over the globe, has a record supported banana company depose elected leader with dictatorship, for corporate profit. )

Hong Kong is Chinese territory since ancient time was leased( at gunpoint ), read some basic history before you make strange comment. I care less about Taiwan( Taiwanese industry are exactly same as China, cheap and affordable, which I as a broken cheapskate very much appreciate ). Remind you Taiwan also claims China as their rightful territory , written in consituition and recieved much economic benefits & help from China than the US ally. In early 2000s Fujian Chinese people supplied clean water to Taiwan controlled isles while Fujian itself was short on water supply. I have many Taiwanese friends and worked in Taiwanese company, some Taiwan friends voluntarily go to Chinese Embassy for paperwork because their rep. Office before was a rude nepotic mess.

Yeah, Nathan Rich had the goods on Hillary’s emails—so someone wasted him.

 

So tell me,  what happened to Ren Zhiqiang?

Thanks but I careless a corrupt, rich, real estate man who ridicule poor people every day, for years. 

How many actual, ordinary Chinese people do you met? How many actuall activists stand against government do you met? You know in our group we despise those famous 'activists' who just show off to get foreign political funding, and do nothing beneficial to the community. Also a certain foreign government only provides funding/asylum for rich defect CCP officials, con artists who could undermine China, but pay no attention to help any real human rights issue.

You are living in a dream world if you think there is less transparency in the west than there is in China. Good luck with that. 

You're living in less than a dream world if you think the world as cold war era, and Chinese people all live in hell, under suppression, would begging for Western military intervention, wow, even as a headache to the local government myself, I don't think we recieved more gabbage news than the POTUS & rightwing shouted 'Fake news!' 'Fake MSM' and blame everything to the left from bad movies to ugly first born. 

Let me live in my 'dream world' and stay out of your cold war mindset. Tell me, how many years you live in China and actually stand against government/police like me does? 

China currently is planning test every single resident in Wuhan, some ~11 miilion, in 10 days window. Whether it's just a stunt or effective measure is still to be seen, but if any country can pull such a massive test done & well orgnized, it'll be China

We'll also get accurate rep. number, cfr etc. as no other country has done 100% test in a large region of populace. Of course some cold wars heads would always scream 'Fake news!'

I think turbocharger subassembly are generally classified at custom as "specialty machine-air pump" under 84.14 & NOT car parts 87.08? Thus should be totally tariff exempt from any form E of FTA countries, eg. China, Australia, ASEAN, maybe Japan, but not US or EU

Anything machinary here is expensive though. Just bought a long reach dial indicator for 2,500 baht... no vendor carries a $5 M2.5 tip extender

I think we usually call 1.3 per year as "loanshark" or "mobster"

And 1.1 per day = loanshark times 1 million billion, or 1 with 15 zeros, think 10% intrest/day for a whole year.

Update. Unfortunate Worldtech stated their policy only do VSR balance on turbos they rebuilt( thus expensive pricing ). Means no bring-CHRA-get-balance service like UK/States tech companies do. 

Trying to contact another 2 company BL Turbo Suotepower and J-Tec Turbo by now. Would update later. Language barrier quite obstacle right now

Update: BL Turbo do balance for 2500 Baht but don't have CT20B jig housing. Sad.

On the other hand I just rebuilt CHRA and measured both axial/radial play within factory spec.

is it locally made in thailand? turbotech? are their turbos same with ihi and other known brands?

Nope imported big name brands will require custom header, support mods etc., their pricing are pretty good only slightly expensive than say in states. Not familliar with 2KD, maybe better choices than those expensive ones but if your goals are very high end spooling like a jet could always pay them a visit. They also have many authentic Tial, Turbosmart parts etc.

Also I've no experience but heard same horror stories on older GTR stocko ceramic turbine, tons of piston/head scoring after wheel shatters and eventually goes the block. Think Nissan had mandatory turbo replacement/rebuild every 60k km.

I think your 3sgte experts might have their have had a rib or 2 removed so they can fellate their own and are feeding you excrement.

Dunno why big names in the alltrac/6gc group have to fellate me, alas I'm only a broken cheapskate, not like them running 4th spot on FOS shootout, making 8s MR2 drag records, building 1400hp on a s***ty toyota 3s block, etc. 

If you have turbo balancing experience locally could share as my post title begs, I would be most grateful. Looking for help not lecture here, if we could both agree there aren't any half decent builder in the world would use s***y ceramic wheels anymore on the CT26/20B turbo nowadays is a fact, irregards whether it could easily destroy an engine when shatters

Worldtech Engineering is a great shop if shoot for higher end, very complete selection, newest Garrett, BW, PT models, spare parts etc.

Myself - I would steer clear of cheap Turbos.

If they fail - and it can be spectacular ! - internal engine damage will be orders of magnitude more than the cost of a well regarded rebuild.

Or purchase new.

 

Of course haven't bought any yet but they seem legit to me, some Holsets are mass produced in tremendous volumn for Chinese diesel/truck/busses thus goes pretty cheap. Not ebay turbone or small factory copies

This one listed as ~4000 baht suppose 35% tariff( actually think China is exmepted )? and negligible freight would be around 5500 mark

cold side typically goes through an intercooler then into the inlet... good luck getting bits of an impeller through that.

 

hand grenading a hot side impeller often results in chunks going out the dump pipe... never heard of them being sucked back into the engine through the exhaust port.

Most will gulped out of exhaust( otherwise my engine would be destroyed already ), but fine ceramic dusts and debris can get in combustion chamber, have two 3sgte experts told me that, they're serious builders do engineering for a living and built many bullet proof big powers.

Plus the shaft/ceramic wheel joining part is a weakpoint very easy to snap that'll mess up compressor and guarantees a rebuild/or new engine.

Just recieved my inconel turbine today, does weight a lot ~214 grams for a small turbo, the 90%-complete ceramic one weighs 104g right now after "forced weight reduction". The thing is in recent 10+ years can't find any replacement 3sg turbine still use ceramic( silicon nitride to be precise iirc ), pretty much each single rebuilder abandonned ceramic shenanigans after tons of horror story, all original TTE race cars and EUDM use steel turbine as well

On the ceramic turbine wheel rant - why would a disintegrating turbocharger turbine wheel damage the engine internals?The turbine wheel is after the engine downstream in the exhaust manifold, there is just no way it will propagate backwards into the engine.

 

The compressor wheel, on the other hand, is a different story, but compressor wheels are always made from aluminum.

Headers are different than exhaust pipe. Collectors have highest pressure and exhaust comes in short pulse. I get lucky because I stopped drive immediately, and my manifold is long twisty equal length also helped.

Why would a company to commit to a low price when unable to assess the level of refurbishment needed?

Especially after you've played with it.

That's why I'm asking in forum and groups for actual experience. 

As a broken guy I must make precise budget plan before posting turbo, even 200 baht wasted could starve me for 2 days. Several UK company openly quoted the price 50-60 GBP if no major damage, and saw a post in US just did balancing the same mark turbo home rebuilt for similar price(two-plane). So wonder if anyone had experience in Thailand for reference/help that's all.

Afterall if balancing here is too much to afford I'll just carefully reassemble live with it, if it later brokes just ship a brand new hx35-type from China, would cost less than 5500 baht total and bullet-proof.

Was it worth it?

Not sure, but new turbos(ball bearing vs journal, improved geometry vs outdated design, lighter housing vs nickel cast iron deadweight) would definitely beat it even if single entry. 

Twinscroll EFRs are superb spool even faster than new G25, but not every twinscroll is EFR????

The manifold I made is only for ease of maintenance not for performance upgrade though, my internal wastegate was failing and good ones are quite expensive
