Okay, so ive determined im getting rid of the m62 and going turbo. I want more power and unfortunatly my power goals are out the the s/c's reach, so what i want to know is what you guys would run(within reason) i would say my hp goal would be in the 350 and up to the wheels. I would like for it to spool fairly fast, i want my mid range power lol. Ive been leaning towards the gt3071r, the only thing holding me back is it is fairly expensive. So im hoping to see what you guys think.


CLIFFS:
Ditching the s/c, i want a quick spooling turbo that holds power til redline and nets me around 350+ whp.

 

What's your budget.

 

eh prolly around 2500-3000 to build the turbo kit.

 

for that price why not go twincharged?

 

I might be selling my Gt2871 if you are interested. I got about 5000kms on it. Ill get you the specs on it if you are interested.

 

i was looking around and found your thread, did you go bigger? im def interested.

eh. to much hassle IMO.

 

do you want internal or external waste gate?

 

im leaning towards external wastegate.

 

Lol, I don't why people say Twincharge is too much hassle. The S/C is already in the car and installed. Intake and cooling system all ready to go. Just feed turbo right into the blower. All sensor connected and good. GG.

But, you would probably be looking at a GT2876R. Turbonetics TO4E would be good as well.

 

well you have to drive to michigan or get them to tell you how they worked the dual boost controller set-up... which honestly cant be to hard to figure out... but with the stock intercooler restrictions iat-2's cant be the best...

and straight turbo will net the most efficient reliable power... imo

 

I may be going bigger. Im gonna be going to the dyno soon but i assume that I am around 320-330ish whp at about 16psi. I was looking with going to a Gt3071 and getting the hann intake manifold and converting to air-air setup. Pm me if you are interested.

 

its just my opinion, i think its harder to maintain/tune etc

yea, im going to continue to research you may have a PM. i want to do the hahn mani too, 900 dollars though. lol.

Do you guys have any particular personal reason for listing/picking out the turbo?

 

16g or 20g

 

that was my suggestion a 20g but he wants external

 

20g comes in both internal and external

 

bump for anymore ideas.

 

and its a journal barring turbo...far from desirable for this guys wish list (read: quick spooling)

a 2876 will be a bit slow for what you want. a 3071 will be about dead nuts on par with it.

your trading turbine size for compressor wheel size, and needed shaft inertia doesn't give a ****.

2871 all day, every day.

it'll pop 350whp with little issue and spool quite nice.

 

I was looking into a 3071 or 3076r.

Brian what would be the ideal turbo to dip into the low 4xxwhp with good midrange power/spool?

 

the only external i found was a cheap obx on e-bay but i didnt look very long... i would never buy the obx...

 

hmmm, just was looking around and the 2871r is around the same price as the 3071r. for the money do you tihnhk i should just do the 3071?

 

3071R is a beautiful turbo, I have one downstairs i'm planning to put on the SAAB. The 3076 is good up to I think 500-550whp, while the 3071 operates in the 450whp range. I would take a 3071 over a 3076 any day as the 3076 takes quite a bit longer to spool up, and if you're going to have a street car I wouldn't even bother with it. The 3071 is apparently almost as quick as a stock turbo to spool (talking about the correct set up now)

3071 also comes with pretty much any option you can think of, I got mine from ATP, was about $1,440.

If you're looking to stay just under 400 at the wheels the a 2871/76 would be fine as well, that should spool fairly quick as well.

 

Quite the project on your hands man. GL!

 

Turbonetics GT-K series

 

thanks im hoping to have it done by the spring c-bus meet

 

i gots you a turbo.. its kinda lazy though
