looking to get some info on a 20g and gt35r

[eagletalonjohn]

i own a tdo5 20g now. i have it on a stock bottom end with some minor head work. i am going with a 2.4 stroker motor this season. now, how many cfms is the 20g> also howmany cfms are the gt35r? would it be worth me putting a 20g on worked 2.4 or is it like putting a 16g on a stock motor with no mods on it? or other terms useless

 

[fwdeclipse]

Well I would not say its worthless but a 20g can flow around 42-44lb/min and a gt35r is anyone correct me if im wrong but is around the 60lb/min area so there is a huge gain in flow there.

A Garrett GT3582R is a 65 lb/min turbo. The HTA variant from FP is a little over 70 lbs/min. If you are willing to spend the money, get the GT35R HTA. I am running one now, and I must say, this turbo is fun as hell. Boosting below 4k and full boost before 4.5k rpms. Price is a LITTLE higher, but worth it.

what site did you buy this from??

 

[Boosted98gsx]

Forced Performance. I deal with no one else for my turbochargers. They're local for me here in DFW, they know how to treat their customers, and build QUALITY turbochargers.

A 20g flows quite a bit more than 44 lbs/min. What turbine are you running? The proper 20g flows about as much as a proper 50-trim.

A 50-trim/20g is good for high 10s and 450whp. What do you want?

 

[1992awdlaser]

Turbo flow is known as lb/min if you didn't figure it out from the other posts. And on a stroker I personally think anything smaller then a 35r isn't enough. My friend evo with a Buschur 2.3l and a gt35r gets full boost around 4000 rpm.

i am looking for like 500 -550 whp. how do you determine what turbine my 20g has? i had this 20g for like 2 years. it has done me right. i am looking to get in the 10s all day long.consistantly. i had a stock motor with tons of bolt ons and ran a 12.7. i dont think thats bad.

i am going with a 2.4 stroker now. 4g64 i know it is built and i am looking to beat the hell out of it.

 

[marcell6492002]

Damn that sucks because I have a 2.3L stroker in my FWD 2g and I just bought a 20 setup from a friend of mine. On his car it spooled at 4000 rpms and I could on image on my car. One day, I will get a gt35r and daily drive it the hell out of it, 30 psi and everything. I know its crazy, but i'm just that crazy.

 

[1992awdlaser]

30psi isn't crazy. I have two friends that drive their cars with 40 psi. One being the evo i mentioned, and the other being a 1g with a t67. The evo has never seen a gas station since he has owned it. He always gets barrles of race gas delivered to his house.

Hey boosted, what A/R did you opt for?

Measure the turbine exducer. Turbine wheel size comparison.

The td06 20g MAY get you to your goal. There is no way a td05h 20g could.

A typical 50-trim and a 2.4 is a heavenly feeling!!!! . . . To me, anyway. There is no real drop off up top. And much quicker boost resonse than you mention. Though a 50-trim won't meet the op's goal, there are several turbos which spool quicker than a gt35r that will meet and surpass his goal.

No propery tuned 20g with run of the mill supporting mods spools that late. They can spool much quicker on even a 2.0L. A 20g on a stroker is a fantastic street machine! And plenty capable of 450+ whp.

did you get the ford 4 bolt housing or the GT 4 bolt housing?


Also how does it feel and whats response like?

Here's one persons take on the gt35r vs 20g btw

I love my friends 2.3l evo with the 35r. I guess one of the reasons is that it gets full boost only 200rpm later than my 50 trim. To me a car thats gets full boost at or below 5000 rpm is a very fun street car. And personally I would take advantage of the extra spool from the 2.4 with at least a 35r. I plan on having my 2.0 with a turbo that gets full boost in the 6000-6300 range so later spool for a lot more power doesn't bother me. I can understand what you are saying also though.

I spent the extra $100 for the garrett 3" v-band out housing.

I'd vomit if I had to wait till 6000 rpm to get full boost on a street car. Saw the exact same thing on "youtube" and it was hilarious, guy was bogging from 2500 rpm all the way up till 5500 rpm. Could read a newspaper in the time it took to spool that thing up. For the street I'll take 3500-3800 rpm spool.

If you're on a stroker, you don't have to worry too much. Little thing called TORQUE keeps you going from light to light, instead of having to rely on a turbocharger. I love my stroker. I will NEVER go back to a 2.0L unless i'm going full rev-to-the-moon racing with nitrous.

I'm not going to be getting on it unless it is from a stop though. That is what I have antilag for. If I was going to get on it from a roll I would either brake boost or use my bottle to get it spooled.

Hmm, I don't know. The torque difference between a 2.0l and a 2.4l at zero boost doesn't seam to be anything to write home about from my experience. With that said, the stroker is excellent for streeting a larger turbo of course, because it creates more volume flow for spool speed and more volume flow per rpm so more flow is yielded at a normal rpm range. There's more torque down low because the turbo spools earlier.

And. . . is brake boosting on a roll or an empty n2o bottle "streetable". . . Sorry, had to pick at ya. I'd be gone if you decided to brake boost running up on me. You're better off downshifting.

I'm building the car for the track so it doesn't bother me too much. I will still drive it on the street but the only time I will get on it from a roll is if I see one of my friends and they want to mess around.

 

[slowgsr]

if your building a stroker, sell the 20g and go with the 35r they are great turbo's you wont be disapointed, you may also want to look into what bullseye has to offer.

 

[definitiveno]

And then if your looking at 35r's you might as well look at an hta35r

Hey that was a three part question.


BTW, they make vband's out of both the ford style housings as well as the gt housings, but I assume you meant GT cause you said 3 inch (since they're both garrett).
