Questions for Justin...

[JusMX141]

Justin, My restrictor didn't do a damn thing (.087") so i went to the head and am seeing only 25-27psi under load and 12 psi at idle (was seeing easily 100psi over 5k RPM at OFH)

You'll blow it immediately with 25psi of oil pressure under load.

justin..to addto my last post, didn't you say at some point talondave was running unrestricted from the OFH with -4an line?

Nope- 7/64" restrictor, no balance shafts, oil filter housing was ported by me so I know it was done and done properly.

10W40 Brad Penn Racing Oil in Dave's engine as well.

I wasn't sure wether to try a plain head regtulator or clipping the OFH regulator's spring first..any suggestions?

So your pressure is too low at the head, too high at the filter housing. You have no choice but to port the filter housing and/or cut the spring a little...perhaps both.

cool, thanks for the feedback, I'll be easy on it until i can get the thing clipped tonight, i'm working on shipping a trans right now that i have to get out today, but i'll get the OFH spring clipped to start with and go from there i guess, thanks!

Justin,
Probably a simple question, but where/how do they measure the cm^2 of the Holset housings. I read they come in various sizes, 16cm, 18cm, etc. Can you tell from this pic what size housing this is? I know it is a HX40W. Do the HX40's come with a T3 and T4 flange? Is this a T3 or T4?

Thanks!!

It's just inside the flange. The carbon buildup can hide it. Also, I've been told by a tractor pull buddy that the numbers on the outside are either 2 or 4 higher than what it is.

Inside the housing lip- some housings are even marked on the outside.

Your example is T4 wastegated, so it's either a 17cm or 19cm.

Justin, you think clipping the spring alone could be enough to get the pressure where it needs to be? I wanna mess with it tonight but don't have the time or gasket to pull the complete housing off and port it. I can get the spring out to clip with everything on the car still.. maybe i'll start a thread about it today, buti'll wait on your opinion first

 

[JusMX141]

I have no clue- never seen someone just cut the spring. You still need to increase the hole size of the oil bleeding back into the pan or cutting the spring may do nothing.

 

[Dyesuperman]

Glenn, if you have a spare spring why not try it out? I know you said you have a spare housing so maybe you can use that spring as a spare as well. It seems you might be the first to try it so if it works it will help out the community and be another solution for lowering the oil pressure after doing the bse. If it doesn't do anything then you will have still helped the community out by letting everyone know it doesn't work on DSMs

Glenn, I considered doing this as well back when I was trying to get my pressure down.

But I ended up doing this: http://www.dsmtuners.com/forums/cyl...se-solve-high-oil-pressure.html#post152321467

can anyone post a pic of a properly ported OFH? I sold my FWD trans today and borrowed a few bucks tonight after the spring couldn't be taken out with out removing the OFH and i bought gaskets, I now am ready to put the car back together with a ported OFH but would like to see some others that had good luck before i put mine on thinking it's right

Is there an 'o2 Housing' which will connect the Holset V-band outlet to the Downpipe? Or do you need to buy the flanges and have someone fab up a solution. Do you have pics of what you did on the outlet side? Seems like there is not much room there...

 

[turboglenn]

There's no pre built solutions that I know of, his get a piece of pipe in a 90* bend and two v bands OBR he right size ( my holset had a 2.5" v band on it from the OEM application. Measure the inside diameter to judge what's needed

Nope- custom-fabbed only.

Purchased a Holset turbo a few months back from a local guy. I bought it thinking it's an 8 blade HX40 but I failed to examine the turbine house and realized it has HX35 turbine wheel. So I apparently have a Hybrid, what are your recommendations for exhaust housing?

I would really like to keep a bolt on with the .55 BEP because of my FP manifold and o2 wastegate, but from what I've read that's not enough flow to take advantage of the compressor wheel.

 

[spydergstftw]

Ok so my friend said that his cousin has a completely stock 1g talon and that he was selling his turbo. But the serial numbers on the compressor housing lead me to believe that it is a small 16g. Justin gimme your input. He said that it was completely stock and never had any aftermarket parts on it.

 

[JusMX141]

Bone-stock Small 16G. Looks to be in pretty rough shape on the outside- not sure what the internals are like, though.

 

[Leonthefaded]

Justin, awhile back I purchased a 14b from the classifieds. I was told about the defeciencies of the turbo except for the fact that the wastegate acuator is old and doesn't seem to be functioning properly. Should I purchase another wastegate for the 14b or can I salvage this one. I haven't used any other method of testing the function of the wasgate other than moving it with my hands (barely moves at all)

Thanks ahead of time

Looks like the head of it is smashed in a little, and it also looks like some put a tack weld or something on the actuator lever to keep the arm from popping off. May take a little creativity to get that thing off, but I'd definitely change it out if you have the option.

Actually, just swap the turbine housing and actuator from your knockoff 16G on this turbo and you'll have a 7cm 14B. If your 6cm 14B turbine housing isn't all cracked to hell, you could probably get some money out of it in the classifieds.

Hey Jus, I thought about making a new thread then I remember this one!

Can an oil drain be too big?

Im going to run my 20g for about half the season before I make the switch to my hx35. I know Holsets require a larger oil drain but, would I be alright welding a larger bung on my oil pan for the hx35 and still run the 20g? I dont want to have to change my oil pan when I do the turbo swap. If I have to I have to however Id prefer not to! Ya know. Thanks man.

 

[JusMX141]

In regards to the drain spec, Tom- it may indeed be possible for an oversized return line to effect oil drainage if you happen to have excessive crankcase pressure as a result of poor ventilation or worn rings. I don't think this would effect the majority of the DSM population, however.

Consider this as well:

1G factory oil drain is larger than a -10AN.

A -12AN drain can't be so much larger than a factory 1G drain that it actually does any damage.

The only problem you may run into is finding a way to connect a -12AN drain to a Mitsu center housing.

Justin.

Currently I'm in the market for a new oil feed line. I've found some decent kits on extreme psi.

I cant seem to figure out the performance differences between these kits.

No need to spend a ton of money on an oil supply line, Leon. Many fast cars out there are running the Bonehead lines from eBay:

Mitsubishi Eclipse 2G DSM 4G63 Stainless Turbo Oil Feed Line 16G, 20G, 14B

I prefer the lines which use a banjo fitting at the turbo on MHI units to slow down the oil flow a little instead of just having an open fitting dumping oil into the cartridge like a firehose.

My bad! I was considering the ebay bonehead lines. But I was under the inpression that its better to run the feed lines from the head, and not the oil filter housing, unless you had a restrictor

 

[crash89]

Youve stated in the holset/garrett oil drain thread that the 2g oil drain is 3/4" OD and .663" ID. Which is pretty damn close to a -12AN correct?! So, wouldnt I for the time being be able to use say the top 1'' of a 2g drain with a 1" hose down to the -12 bung on the oil pan? Then once I make the switch just run a -12 bung from the holset center section?

 

[Leonthefaded]

I'm in the middle of tearing down this 14b turbo. After following a few youtube video instructionals and your step by step guide on turbo rebuilds. I seem to have broken the shaft at the nut on the compressor side.

I have an ebay knock off turbo on my car currently I also have a stock evo 8 turbo sitting infront of me. Will either shaft work as a replacement?
