Default Boosted baby!!!

I finally joined the club today!!! Installed my custom td05h-14b and she's workin pretty well in my opinion. Seeing 4psi of boost at 2500rpms or less. I only tested it for a couple minutes. But, I noticed a few things. Fuel pressure is only getting raise to ~50 psi. But I have the safc-2 richening things up a bit, so I'm still good.

The only other annoying thing I noticed, was when I let off throttle (light throttle, no boost) I get a high pitch whining noise coming from around my turbo (like resonance for a second or two). I pulled the vacuum line on the BOV and it went away any ideas waht that could be? I'm using a crushed DSM 1G BOV by the way. Going to get a noncrushed one soon.

Anyways, I'll have pics soon if anyone wants to see. I'm dumping to atmosphere and surprisingly it's not that loud. Of course it was raining and I didn't really have the windows down. But the turbo spools insanely quick and it's very quick up top. Going to take a highway cruise in a little and see how that goes. Hopefully nothing will blow up.

Yeah after some problem solving I found that the noise was coming from the BOV return line note completely sealing. Problem solved!

This thing screams up top...literally. My buddy seemed think that it was louder than faster, haha. 14b is a pretty good choice. It doesn't have a ton down low (barely noticable) but when you hit 4k or so it pulls hard. It easily pull to 100 where N/A I would need a nice long straight.

I definately need some more tuning as my EGT hit 1375 MAX and I'm running 2 degrees of retard from 2400 up. I have some work ahead of me, but for now I'm just glad to have the setup in.

The coolest thing is I can swap in a 16g without changing a thing. In case anyone is interested it's basically a DSM turbo setup and was fairly inexpensive. 14b turbo cost me a whopping 150 bucks!!! And I'm running a modified saab 900 intercooler I got for 53 bucks

More than anything I'm excited that it actually works.

Thanks to everyone for help along the way!

Where did you get the modified up and downpipe to support the 14b? Also the turbo itself and oil and coolant lines. I would love to be able to install a dsm turbo on my car. I just came over from the dsm cars. It would make me feel more at home



Thanks

Tom


P.S.

Thats the reason why I post so many questions

I had an exhaust shop custom make the up and downpipes for me. The factory wastegate hole is blocked by the downpipe flange and I'm using a tial 35mm that's venting straight to atmosphere. The lines are a little iffy, but they're holding I just took the stock oil feed and return lines from a DSM and cut them up and then jammed some steel braided lines on them (required a little dremeling of the stock lines) and then hose clamped them on nice and tight.

Getting the pipes made took the most time for the whole project. Though anyone that is somewhat competant with exhaust should be able to do it. I ended up spending the day down at the shop and telling the guy exactly what to do and he'd make the bends and the welds right where I told him.

I'll get some pics up after work, I have them on a different computer.

The only other thing I haven't really solved yet is the pipe coming from the 14b compressor outlet. The stock is like 1.5"-1.75" diameter and I only had a 2" connector so I used a little duct tape to widen the pipe up. I guess it's holding for now, but RRE or Buschur sell 2" outlet pipes, so that's on the list of things to buy. I regret not taking pics of the pipes before I installed them but you can pretty much see how the setup is.

Also, I'm dumping to atmoshepre cause I'm running the stock exhaust. The same guy who made the pipes for me is going to do a 3" back from the downpipe...and we'll get a cat on there as well

You may want to widen the end of the oil feed line goind into the turbo,also double clamp it,you dont want it to blow off.trust me

Default Some pics!

Here are some pics I took yesterday. I'm going to do a little more work today and I'll get a few closeups of the oil lines, pipes, and wastegate routing. Enjoy!



hondaslayer: I deburred the pipe that was used for the stock line after cutting it to make sure there was a smooth transition. I didn't see the need to modify the banjo fitting because I thought it would act just like stock...maybe I'm wrong. I'm not too worried about it blowing off though, I had to use a dremel to cut the steel braided line and hose to get it off after I test fitted it. It's on there REAL tight


they're on this site

I did as well,the thing is it gets under pressure and blows off,so you may want to take a tool and ream it out a little.


Congrats!!

Ben,

Default More pics added

I added 15 more pics I took tonight of various stuff. I tried to get some good shots of the pipes. Hope that helps, next time I get them off I'll take a full shot of each pipe and of the turbo with the pipes on it.

I also have a full parts list if anyone wants it. I just have to update with the last few things I bought.

Hondaslayer: I tighten my oil feed line hose clamp a little tighter just to be sure, hahaha.

Off to take a spin and hit the bar

I saw you tapped where the stock oil pressure sensor is for the oil feed line. Where did you put the stock sensor after that?

On the backside plug. The line wouldn't fit in the back because the IAC was in the way, so I just swapped em.

Looks good man. I have a small 16G lying around that I might be using on my RS, from an Aussie STi. If I put it on i'll let you know how it feels. You say the 14B is pretty good in the higher RPM's though?

Yeah that'd be awesome! I can swap a 16g in without changing a thing, so that's definately something I'd like to know about.

I looked at the flow maps today for the 14b and running 4psi it's definately not at it's peak performance. I'm seeing maybe 55% efficiency in the low rpms...but the good news is at 6psi it looks great (theoretically) across the rpm range. This definately isn't one of those torque monster down low turbos.

But yeah, you can really feel it kick in up high (after 4k). If I had to say, I'm roughly equivalent to something in the 190's to 200's crank. Not WRX territory yet, but getting there. Tuning, new exhaust and a little more boost will probably go a long way.
