He is currently on a divided t4, not t3. I agree about the .63 being a single scroll housing.....I wonder how tiny the hotside would look on a .63 t3 divided.

 

Right I'm T4 TS.

I didn't think they made that housing for T4's but i wasn't sure

 

I forgot he has a PTE turbo. I know Garrett has a 1.06 TS T3 divided housing which in T3 form appears bigger than his T4

I see on PTE site that there is no TS T3 option... All these companies doing things differently.

 

Just do the 6266 upgrade and keep everything else the same. If that isnt your bag just do a 6262CEA and have great spool and power.

 

Look at 240Z TwinTurbo's thread for how the Garrett's perform in a T4 twinscroll configuration. LOTS of good info in there.

I wish he had gotten a chance to test a TS GTX3071R as I think it would have shown some good gains in response over the GTX3076R while making similar power. But anything with the GT30 turbine wheel will not make huge pump gas numbers unless you sacrifice response and put a massive turbine housing on it.

If weight in the car isn't a primary concern, T4 TS is the way to go.

 

persionally I have a t4 divided hta gt3582r

for your goals I would recommend a gtx3576r with a t4 divided 1.06ar turbine housing.

 

GT3076HTA with 1.00 T4 TS Housing
GT3582HTA with 1.00 T4 TS Housing
EFR 7670 with 1.05 T4 TS Housing
EFR 8374 with 1.05 T4 TS Housing
Borg Warner S300SX FMW(Basically EFR 8374 without ti-al turbine wheel and stuff) and a lot of T4 TS Housing choice

 

7670. After driving mine on pump. Oh yeah. /thread . Waaaaay better than anything stock framed.

 

yeah if they were available

 

i am running a T4 1.15 housing from PTE. what does that have to do with this thread? i have no idea i di not read it. i just saw all the TS talk haha.

 

since you cant get a EFR borg warner why not take a look at the new s300sx fmw turbo, supposedly better spool and transient response than a hta 3582r and it still has the same top end. it has the amazing reliability of borg warner and it can be rebuilt. they retail for $1,100 from full-race and they are having a sale right now!

 

LOL. thanks ido that to threads from time to time. i guess i had that coming.

Close to making a decision. Thanks for the comments guys

 

Is there any factual info to support some peoples assertion that the garrett based turbos don't flow well in twin scroll config.

Right now i'm between a 5857CEA/5858CEA, HTA82 or GTX3071.

Its hard trying too look up info for these choices and there are so many intelligent opinions pro and con for these choices it makes picking difficult.

 

the CBRD lmp kit looks pretty damn appealing with a 33rb. flows better than any stock frame, still makes awesome USABLE power and sorta limits you so you dont want to make 700+ one day

 

At some point its a matter of brand preference. I'm partial to big OEMs that have had their turbos beat to crap in all out racing conditions.

My progression through power levels would be: gtx3071r>efr7670>gtx3576r>efr8374. The power you can extract from them will depend on your setup so you have to factor that in while picking a turbo too. This is where the difference between one shop's built head over another's will make a difference, and so on. So pick a target power level and pick the smallest turbo your setup will allow to hit that target. And enjoy the spool.
