TD05 Turbine Housing Options...

[rburnett]

Hey guys I've got the Talon's big brother, a '95 stealth. It's an N/A model that I converted to a single turbo. My setup was originally designed for the 16g because, that's what was available at the time. After a few months with the setup, I have realized that this turbo is painfully small. The compressor side isn't a problem since it flows enough CFM for my boost needs(7-8psi), but the turbine is painfully small for this 3.0L engine(even after I did some MAJOR porting to the 7cm^2 housing). At WOT in 1st gear, I get 1psi boost at 1500rpms . Talk about spoolup! However, it really chokes the power after 4k. My question is, what "bolt-on" options are availible for you guys as far as aftermarket housings? I've heard something about 8cm and 10cm housings, but no pics or info on them. Do they bolt up to your stock manifolds and O2 housings? What kind of boost response do you get with the larger housings? I know it's not quite the same on 2L as it is on 3L, but I need something to go off of. I need more flow, but I also need (7-8)psi by 3000rpms. Any thoughts?

slowboyracing has a 20g tdo5

I don't know how turbos respond on the 3000GTs. I'm running an evo16G turbo and I don't get spoolup till 2300 and full boost at 3200. I'm just guessing that your hopes for 1500 rpms making real boost is kind of high expectations.

I know you can get a 7cm. I'm no expert but that would probably hurt your spool up. It would give more space for the air to go around the turbine instead of in the blades of the turbine. Like when you get your turbine clipped they say that you will have a higher top end but your spool up suffers a little. If you want a quicker boost and aren't pushing any high amount of boost get a 14b or 13b turbo they are mitsu turbos so they should go in there quite easily.

i mean.. if your set up works like the mitsubishi design 14b, 16g type stuff.. you could get a t3/t4 hybrid 50 trim that could bolt on to that.

 

[David15151]

he is able to spool a 16G faster then we can because he is using a 3.0 6 cylinder compared to our 2.0 4 cylinder. He wants a bigger turbo that bolts on to a mitsubishi style manifold / o2 housing type.

 

[johnk]

He said he's running 7-8 psi he doesn't need a 50 trim to do that.

Hes talking about the turbine housing itself. Its too small for his 3.0 vs our 2.0 so its choking his engine. You cant compare the spool up of a turbo on your car and ours. I would think you need something along the lines of a 10cm housing. But I dont know if the small turbine wheel would like a housing that big. People with the bullseye housing which is almost like an 8cm housing are still getting decent spool on our 2 liters if thats any indication of what an 8cm would be like on your car.

You missed it completely. I have the 7cm^2 turbine housing. I'm looking for a larger aftermarket turbine housing that bolts up directly to the stock DSM configuration without adapter plates or wleding and the like. My only requiremenst boost by 3000prm. I'm looking for information/experience/pics or anything else about the 8cm and 10cm housings or any other housings that accomplish the same thing.

Damn. You guys post fast!

"Decent Spool" with the Bullseye housing, what are we talking about 3500? 4000? On your cars?

BTW, the base stealths redline at 6k, not 7k so there is less rpms to play with which is the only reason why I don't want fo go too big. If I can get boost by 3000, that gives me at least 3k of usable power.

I get 1psi boost at 1500rpms . Talk about spoolup!

I thought you were going for fastest spoolup not the biggest compatible housing.

Like 3300 heh. So I guess its still relatively fast.

you can get this http://turbochargers.com/Turbos/TurboUpgrades/Godzilla5.htm or a TD05H 20G. You can also just do an EXTREME clipping on the turbine wheel to get more topend.

How does that compare to your stock 6cm housing? Just trying to guage the increase and translate it to 3.0L I'm assuming the response is the same on 1st and 2nd gens with a hypothetical 6cm 14b correct?

You said an EXTREME clipping, something like 20+ degrees?

 

[ZenkaiRacerDsM]

A turbo is going to spool a tiny bit faster on a 2g due to the higher compression ratio. Normal spool up of a 14b is like 3000rpm. So the bullseye housing though it flows a shitload better only hinders spool up by 300 or so rpm. I think the 10cm is for you. If it does in fact bolt right up like an 8cm like I am thinking it does.
