I thought about that, and asked my wife if I could get a 42R, and she said: "after I get a "set" of 42 Double D's! ". just kidding of course.

I want to keep the A/C, and if the price for that is 7500, I would have to buy injectors/fuel-rail/top end/bottom end, etc.. and all the extra, to me, is not worth an extra 70-80 hp. Thats just me. Isn't 10 seconds fast enough? I want to road race it also.

 

Trust me, you don't wanna be like me ... mo booty = mo problems

Good information to read, thanks.

 

Another interesting thing is the "trims". ie: 50 trim, clip this wheel and that, etc... Is this for spool-up, or for HP gains?

 

haha its actually 19.8 lb

 

if you are going to road race a 10 second car, you are one bad *** ****!! haha that would be a scary trip around the road course

I personally dont like the gt42R. I feel you can do as much with a heavily modified 40R and pickup about 1000rpm earlier spool. just my opinion!!

 

This is what i call a gt3037R



http://www.full-race.com/catalog/pro...products_id=66

we rate it to only 480whp however i feel we can break 600whp with the appropriate setup. Here is a comparison of a gt3037R vs gt35R, both .82 a/r turbine housings on a b series honda.




We have been testing with modified garrett R series turbos and have had excellent results. We will have our own versions of the GT turbos available for sale soon, the testing of our reworked 40R has been great, the 30Rs will be tested shortly. I prefer this turbo to the 3071 and the 3076

 

Correct me if Im wrong... the 3076 make more pwr right?

 

what is the most popular 35R

as far as options go...
eg trims,wheels etc...
4bolt,5bolt..??etc etc...

also which combo would make big power without much lag?

 

Also why? Do you also recomend a gt series turbo with a big back housing? You mentioned that this was on a b series honda motor, will this turbo behave the same on the 4g63?

 

Ok there are so many confusing names for the same turbo, its hard to keep track.

The GT3076 is what Garrett has for years (until this one) called the GT3037. This is a ball bearing center section with a gt30R turbine wheel and a 76mm exducer turbo. This is the turbo i am referring to, however we (Full-Race) modify the compressor and turbine housings approrpiately to improve their performance. I definately recommend gt turbos with the proper turbine size. Each turbo and engine setup will have an ideal turbine housing.

The 4G63 will behave VERY similarly to the B series, if it is properly modified, and vice versa, an improperly modified b series engine will make less power than a porperly modified evo motor.

That being said, Headwork, Camshafts, an excellent intake manifold (this is the hardest part as i havent seen many that can be considered properly designed), good turbo system, good intercooler, and a proper tune will all be necessary to make these power levels out of the turbo. The end result, however is fantastic. Great spool, huge broad powerband and instant throttle response with very little cylinder pressure.

 

I would say the most popular 35R right now is the standard 35R, .82 a/r. This is an excellent mid-high power turbo with very good spool and throttle response characteristics. We have seen far more power out of this turbo than we ever expected, and it really is an incredibly well engineered turbo. Its easily available and fits a wide range of turbo kits. 4 bolt outlet is ideal as 5 bolt is more on center (Doesnt flow as well) and doesnt fit nearly as many applications.

That being said, in the coming year, i expect the GT3567R to be more popular as it will exhibit identical spool characteristics with the same boost threshold, yet be capable of even more power. This turbo is very sensitive to proper turbine housing size and is very rare, but is amazing what can be done in the t3 frame

 

Dam great info Geoff! you have all the answers WE are looking for, its like we are sitting on your lap for "story-time"! keep all the great info comming. Who else comes on here and explains the differences, and helps us out!? I can count em.

 

ime thinking 3037 with a .63.........

 

cool..thanks for ans my question...well that's exactly the turbo i've got.
the 35R with the .82 back...but I've bogged a few times on the line esp due to lag .so I ordered the smaller back end..I believe it is the 0.63
and well i'll still have the 0.82 so ill see how i like this for the while
