Tomioka turbos
I was wondering if anyone has any real world experience with them? I'm looking at either an Tomioka 18g or vf48 for my 05.

11-10-12 Purchased a Tomioka TD05-18G Pics below

11-17-12 Turbo installed Pics below

11-18-12 Turbo removed due to failure... WTF (Pics and Video added)

Nothing wrong with them but the VF48, imo. The OEM STI VF48 is almost inbetween an 18g and a 20g from I've seen. Close call, maybe just whichever is cheaper.

Went with a Tomioka for peace of mind. Not enough of a price difference to justify a buy a used turbo.

Put up some pics and let us know what it puts down after install. I'm thinking of going with the same one this spring.

I would've went Kinugawa personally. Maybe i'm just biased though... :D

Which Tomioka did you get?

Turbo just arrived. I went with the td05-18g. I read about the kinugawa turbos but it appears those require an up pipe spacer. Here are a few pictures. It seems to be a very nice piece, especially for the price. I'll be installing it this weekend.

Very nice turbo and good choice on size!

Yes my Kinugawa did require a spacer but that was included along with its adjustable wastegate actuator. :D

Cone_Killer 11-13-2012 07:03 PM

The Tomioka also utilizes an adjustable actuator.

Turbo went in today along with new coolant hoses, gaskets, oil drain, and replaced the oil feed filter. Some things I noticed about this "bolt on" turbo:
Compressor outlet flange bolt holes are wrong (too close together)
Right side of the compressor housing hits the crankcase pcv
Coolant return/outlet is turned 45 degrees upward, causing fitment issues

Here are some pics before the install compared to the vf46 that its replacing.

We have a huge problem. After the first set of build quality problems, I should have suspected something else.... So after priming the turbo, pulling the fuel fuse and turning it over 5 times for 5 sec each and oil started coming out of the drain tube, the car was started for the first time. I let it idle for about 10-12min letting the packaging oil burn off but noticed that the smoke coming from the exhaust was far too much to be assembly oil. So I shut it down and left it in the garage overnight to try again this morning. So upon startup this morning, same thing, billowing smoke out of the exhaust. I drove it down the street (out of boost) and the only time it doesn't smoke is under continuous acceleration. It smokes while cruising and initial acceleration. My car has never once even thought about smoking. THIS TURBO APPEARS TO BE BLOWN BRAND NEW!!! Words cant even describe how pissed I am currently. I will be contacting Tomioka and Import Image Racing where this turbo was originally purchased.

Professionally speaking, do you see any problems with my install procedure?

But you didn't go into detail. That's my only "what" concern. Which is a big one, especially once you drove it after that.

I slid the rubber oil drain line up so I could see when oil was coming out of the drain. I turned the engine over without firing until oil was coming out of the drain line (just to make sure the oil had circulated through the turbo before starting). I reconnected the line and started the car.

I just pulled the inlet and the intercooler thinking it may have been pcv. After doing this, I wiped off the outlet and started the car. Holy shit, the compressor is spraying oil out. Check out the video.

I don't understand, how is it blown out of the package? My biggest issue is that I purchased this from a member on Nasioc. He bought it a couple of months ago from IIR, changed his mind and went rotated. It was still new in the package when I received it. Not sure what my options are but I feel like Tomioka should stand by their product.
