Ok so here i have a B16a 2gen fully built here are its stats

- Benson sleeved with 81.5mm bored (.20over)
- Cp pistons 9.0:1 comp
- Manley rods I beam turbo tuff
- Full ARP hardware
- Full ACL bearings

And im debating with witch turbo between the GT3076r or the GT3582r should i go and would be the best for my setup. My goal is 500whp and also its still gonne be a street car so i still want a nice spoolin time.

I made some quick calculation and here is what i came up with on 22psi. the red dots on the comp map are where I would be on the map in efficiency.

(22+14.7)/ 14.7= 2.497 T2 = T1 (P2 ÷ P1)0.283 535 (36.7 ÷ 14.7)0.283 = 377.99751700680272108843537414966 °R (535 ÷ 656) × (24.7 ÷ 14.7) = 2.04 Density Ratio (96 × 8400) ÷3456 = 233.33 Actual CFM 198.33 198.33x2.4=475.2 475.2x0.069 = 32.7888 Lbs/min

The GT3076r:


and

The GT3582r:


If my calculation is wring let me know.

need some help to decide witch one i should go for as you can see on the comp map the 35r is way out of efficiency and probably looking around a 5900rpm full boost.

But i might be wrong so thats why i need you guys help to help me decide witch one i should go for and i also have a little worry of maxing out the gt3076r.

If anyone of you have some dyno graphs to proove an opinion post them up i will be glad to see them haha.

have yo looked into a GT3082R a customer car of mine with a 4g63 and a 3082r(FP3065) made 484hp at 25psi on pump 100

For your WHP goals there is not question about it. The GT3076R is the PERFECT turbo for your goals. The GT3076R is capable of making 550WHP as it has been done before. Its spooling characteristics are great and I can assure you that you will succeed at reaching your WHP levels. /Thread

i think your math maybe off

step 1. firgure out PR
step 2. compressor idea output
step 3. compressor actual output
step 4. density ratio
step 5. displacement
step 6. 100% VFR
step 7. actual VFR
step 8. VFR multiply density ratio to figure out MFR
step 9. MFR multiply pressure ratio (PR)

or PM me and i can excel chart everything for ya

haha yeah i could be off a little

thanx guys keep it upanyone had experience with gt35r and b16a ?

get the 3076r and call it a day. a 35r would be overkill, with unwanted lag.

agrn93ls

Built B16a GT3076r or GT3582r ? neep some faqs and opinion

faqs and opinion lol

just looks like somethin else.

DRIVENRacing

3076r is something else.. i am in love with this turbo, and for the street there is NOTHING better...

fmfkid250

this is a local kid around here with the 35 on a bone stock b16 put down 407whp @ like 15psi (I forget)

Bigger turbo the less boost you will need to achive your goals and the less boost the better it is for your motor

I agree...of the two choices, the 3076r would be my choice without a doubt. Even if you dont make your power goal (which i dont think you'll have a hard time doing w/ the 3076r regardless) you're still going to have a fun, fast-spooling turbo that will be a lot more fun on the street

agreed. and make sure you go with the .82 A/R exhaust. will hold torque better and allow you to reach your goals.

Schister66

just to throw it out there....

you know you dont need a $1300 ball bearing turbo to make that kind of power. There are plenty of other turbos that will make the same power as the GT30r and spool just the same. You're in the range where the GT30r comes into its element, but just make sure to look around before jumping on the HT bandwagon

If you go to http://stealthmodeperformance....shtml you can put your numbers into an excel chart that my bro made.

I almost got rid of my Master power Td04e turbo has a .84 exhaust side.

In favour of the gt3076R as everyone had suggested on my gsr set up.

from my experience. Anyone who has come in my car and taking a ride in it, absolutlely loves the way the car drives! i dont make full boost until 5800RPM. BUT my short gear type R tranny with 7lb flywheel comphensates for that. The car revs very quickly.

Best part about the set up, the car is making over 300whp on just the basemap, not even tuned yet.

I dont break loose in any gear. My 1st gear full boost by about 7krpm. slam second it hooks and goes. Alot of ppl tell me the feeling of my car is like an all motor car on Steroids with the drive feel of a AWD car. Bigger turbo's just pull and pull and pull in your top end power band@!

Thats so funny you made this thread! I'm in the same debate you are and it answered all my questions.

rs250nut

You will end up buying two turbos if you go with the 3076r, you will get bored of the power and want more then end up buying a 3582r or maybe something from the precision range for a cheaper better turbo

dpetro1

im gonna switch my vote...with a sleeved motor i think your whp goal should be higher. grab the 35r, crank the boost, and aim for 600whp.

flatblackhatch

ummm s362 worked fine for me and had a great spool time but if i was you 35r leaves room for more

E85B18

Not true. I made 489whp on Saturday on a 3076r (20 degrees of timing). With that kind of power and the spool I get there will never be boredom.

Boy, this is really, really old. I think the OP has moved on from this, as well as subsequent bumpers of this thread.
