Questions for Justin...

Justin, 20G feed from the ofh with a .78 restrictor is ok?

 

[JusMX141]

im picking up a 6152 BB with bolt on housing, what type of oil feed should i be using?

Good question for PTE- I have no clue seeing as they don't use Garrett GT cartridges. Sadly, they probably don't have a clue either.

Ideal, actually.

Hey Justin, I have a Hahn S16G and it is due for a rebuild. But I have been thinking of upgrading to something a little bigger. Have looked at the S20G and HY35. With my current setup, I can not run anything above ~22psi. Whith that said do you have any suggestions on a good streetable turbo that is under 1000?

 

[JusMX141]

Definitely not the HY35 if your desired boost is under 22psi. I'm figuring a simple 20G upgrade would fit the bill with an option of going to a billet wheel for better spool and/or efficiency.

Hi Justin.

I have here an TD05HRA-16G6-10.5T from an EVO 6 TME RS2, tial turbine.
Nice condition but i look for a good rebuild kit.
Let me know if i could use a TraderGreg TD05 kit or maybe a best mind like thrust bearing upgrade.

Thanks.
Remy

Thanks. What would be a couple good viable choices for a t3 flanged 20g. Preferably journal bearing as well.

Hey justin. Picked up this turbo With a bad 20g wheel. The seller told me that the evo 3 16g housing was machined for a 20g wheel. There is a fairly big gap between the wheel and the housing. It apppears it wasnt done correctly. I would like you opinion.

 

[JusMX141]

Holy balls, I can see the exducer tip.

Either that's not a 20G wheel, the housing was machined wrong, or someone's using a 20G compressor behind a cover that's cut for something larger like a Frank 20G or FP Green compressor.

I knew it wasnt correct. It is a 20g wheel though, I measured the Inducer and is the correct MHI 20g wheel. How can i tell what wheel will fit correctly in the housing? It doesnt look like a wheel with a much bigger Inducer could fit.

 

[JusMX141]

No clue unless you had some other wheels there to try or a list of all the possible wheels with their corresponding measurements.

Justin, light light blue smoke pops out of the exhaust right as i hit boost, everything alright?


The other day i drove 2 blocks (2 minutes) with my valve cover lines looped (forgot after a BLT) and smoke came out of the back like crazy. Pulled over unlooped lines. Drove car for a half hour, smoke went away. Now days later it still pops a small translucent cloud soon as boost hits, you think i effed a seal? Or could it e residual oil from when it passed through the few days ago?

If it is indeed a seal issue, can you hook it up with a rebuild kit?

I habent pulled off the o2 housing to see what the blades look like, if their coated I'll shoot it with some break clean and see how it looks in a few days. Compressor looks new

 

[JusMX141]

Could've hurt the turbine sealing ring while the crankcase was breathing through the turbo- would be impossible for me to diagnose without the turbo sitting in front of me.

 

[Archer Fabrications]

I'll look into it and come back with pix, in the mean time, any harm in running it?

What can all cause boost pressure off the wastegate to drop? Back in january my friend got his 240 tuned at 13psi straight off the wastegate. Nothing has changed since then, but now it only hits 10psi. Its running straight off the wastegate, no boost controller. Its a tial external wastegate. We checked for boost leaks and vacuum leaks and everything is fine.

 

[delta448]

Heat fatigue of the spring.

 

[Kyle_T]

Thats what I originally thought, just the spring getting weaker. I think its time to throw the manual boost contoller on.

Hey Justin: Comp CT3 line turbos, whattya think of em? Can they be rebuilt? The JB versions, of course. Ive heard good things but i wanted to ask you first. Im still leaning towards built hx40 but the selection of comp turbos is great and the price is nice too. After a rebuild, the right comp wheel and a turbine housing the holset would cost damn near as much as a JB comp.

 

[Archer Fabrications]

Hey justin, what do you think about the hx40 vs the 3794hta, they seem to spool the similarly but 3794 is quite a bit more beastly. I know its not really apples to apples with the 67.5mm compressor... but im curious Just kinda dreaming about what could be next someday.

Maybe a more important question, is a -12 drain too much for a bb garrett? I wouldnt think so. But you never know. Ive still got everything to run a bb turbo fed off the head.

Use seafoam to check for preturbine exhaust leaks too.

Spring is worn. Use a MBC to bring it back to where it was...but don't plan on running above double the amount the spring is rated at.

Comp is the successor of Innovative Turbo, which were primarily garbage. Any time an aftermarket company designs their "own" journal bearing turbos that are based on a Garrett T3 center housing, reliability tends to suffer (Precision, Turbonetics, Master Power, etc).

WTF

You realize you're comparing a 60mm/86mm wheel to a 67mm/94mm wheel, right? This is like asking how a Small 16G compares to a FP Green.

Maybe a more important question, is a -12 drain too much for a bb garrett? I wouldnt think so. But you never know. Ive still got everything to run a bb turbo fed off the head.

Ball bearing cartridges drain such little oil that I'm sure it's larger than necessary, but I don't see how it would hurt anything unless your crankcase pressure is off the charts.

 

[Archer Fabrications]

I knownits not apples to apples but it still spools the closely. There are upgrades tothe 40 that put it in close shoes with the 37r... Lol

Not really. You are basically comparing the HX40 to an HX52.

 

[Archer Fabrications]

Except the 52 is physically enormous compared to the 37 and hx40, i guess the 52 is an option, looks damn near brand new now after all the work.

It's really too bad it has to be so large. Would be an interesting time mounting with a .70AR machined housing.

 

[99gst_racer]

Justin, is there a specific name for the v-band clamp that holds the CHRA to the turbine housing? And, do you know the part number for said clamp for a garrett GT42r?
