sleeper 16g

[dan2288]

Right now I have a big 16g and im thinking about stuffing a 20g wheel in it. I dont want to spend a lot more money on the car and this seems the cheapest way to go. What exactly do I need to do this? Just the 20g compressor wheel? Is the turbine wheel the same? And how much will I have to machine the housing to fit the 20g wheel?

 

[viperlp01]

bastard 20g is what it is called.. search that name

 

[dan2288]

I searched, didnt really say what is needed to make one

Check out SBR, they usually have them floating around on there.

The backplate of the Big 16G, Evo III 16G, 18G, and 20G compressor wheels are all the same diameter. If you're replacing a Big 16G or Evo III 16G wheel with a 20G wheel, the only thing that will have to be machined is the compressor cover. If you're replacing a Small 16G compressor, the center housing will also need to be machined to accept the larger compressor backplate.

Most Sleeper 16G / Bastard 20G's use the TD05H turbine, although there are some out there with TD06 and TD06H turbine wheels that are better-balanced to the flow potential of the 20G compressor. I honestly feel the TD05H turbine is fine for a turbo like this because your flow potential is going to be limited to what the TD05H 16G compressor cover can handle.

Ok, so I just need a 20g compressor wheel. How much does the housing need to be machined?

You could do the above and then sell your current wheel/housing for a little dough!

 

[JusMX141]

How much does the housing need to be machined?

.018" will need to be removed from the inducer area if your current turbo is a Big 16G, although there will be correction needed to the apex of where the wheel meets the housing. You can't just punch out the inlet / inducer area and slam the new wheel in there....the person trimming the housing has to know what they're doing.

 

[dan2288]

Are there any shops that can do this?

 

[dan2288]

Could forcedperformance machine the housing?

Hahn Racecraft - Turbo Upgrades and Parts

Hahn Race craft most likely has everything you need for this upgrade on this list.

I beleive the part#'s you need are the h-rp 1035 & 4055

looking at around 600$, but thats pretty good becuase you just brought your turbo potential from maybe 350hp to 450hp for relatively cheap.

 

[viperlp01]

600 dollars will get you a holset and a bep housing that will make 500 hp and has more potential... 600 dollars is way too much to upgrade a 16g to a sleeper 16g

 

[dan2288]

well I can get a 20g compressor wheel for 180 from forcedperformance and I could get the maching done maybe for free or really cheap. So it doesnt look like it will be too much. Doesnt seem too bad to make alittle bit more power. I really wont be needing a bigger turbo untill I build my motor anyways.

 

[oldman420]

I'm confused in your profile your engine seems pretty built to me

 

[dan2288]

sorry, I gotta change my profile. I dropped In a used motor after my last motor bent the valves.

 

[dan2288]

I just updated it

 

[oldman420]

If your engine is stock then i would just leave that 16g for now, spend your money on better things and when it come time to finally upgrade your turbo, do it then.

 

[oldman420]

you do have good fuel upgrades, dsmlink?

 

[boostedorbusted]

the holset option above sounds more benifical and will yield the potential for more bang per dollar. thats the route i would go.

 

[oldman420]

sorry i just read stage 3 chip, maybe it would be worth it to upgrade that baby 180$ from fp and a little bit of machining almost seems worth it. I think you may have even convinced me to do so.

600 dollars will get you a holset and a bep housing that will make 500 hp and has more potential... 600 dollars is way too much to upgrade a 16g to a sleeper 16g

Some people want sleeper look, and some need it. I would love something like this being in California, and since it would cost you around $1k for a 20g or 50trim turbo the upgrade yielding almost the same power potential is pretty nice.

wheel and cover

That's not bad considering the price. I wonder how well it would hold up though..

 

[oldman420]

Well considering everything else in my turbo is HRC i wouldn't but if i had just a generic td05h i might be tempted to try that ebay item.

 

[gorf]

another option - look for a 20g that needs rebuilding.

I picked up a 20g that needs to be rebuilt for cheap. I was planning on just using the cover and compressor wheel, (less than the ebay item) but changed my mind and am going to rebuild it and use a td05 housing that I have.

I am hoping to get near as fast spool as my 16g with an extra 40-50 hp capability for under $250

 

[dan2288]

should I get a tdo5 or tdo6 wheel? Does it matter?
