Anyone experience GT3071r v GT3076r

[EGB18CT]

Hi Guys,

As some of you know my turbo project has begun, slowly at least, im about to purchase the turbo for my 'kit' running of a t3 spoolin mini ram manifold tial 44mm gated (pictured in other thread) now im torn b/w these two trubos. Motor will be fully built, 83mm, 9.5-1cr, built head bla bla.

Has anyone got any REAL advice between the GT3071r t3 .82 and the GT3076r .83 (aka gt30)? Aim is some nice midrange with about 400'swhp peak

Searched heaps and heaps on H-T, but its all swish wash crap talk.

[dai-16t]

I had to make the same decission not long ago.

I ended up going with the 3076 and tial .63 rear.

You will make that power(400) with the .63 and it will have more midrange than the .82.

[bighaks]

go the 3076 with .82 rear

[EGB18CT]

^how is part throttle and transition boost with the 76 and what rpm are you getting full boost?

There are some .63 and .82 graphs.

the same tuner so you can rule out different dynos or operators. In other words even if the figures are overstated you can still judge how boost comes on and where torque peak is at.

[dai-16t]

The 3076 with either a .63 or .82 will make the power regardless. The different rear will change where in the revs it makes the torque and hp.

[EGB18CT]

thanks champ^, i've been looking at heaps of graphs off evans tuning too, the ones you listed are very similar to myu build, ive just got to remember that i cant fit a too big turbo due to the way i have my manifold and wanting to try run a full radiator, ill also have a very tight oil return therefore also restricting what i can run as it will sit low to the pan. We shall see how this goes, if its all well have a bit of fun in it, practise, then wack on a top mount and and gt40 down the track, atm looks like ill order the gt3076 in a .82, and should be sweet for a while :) rep 4 your efforts too...

[Weq]

76 with a .63 if its a street car.

71R reacts really badly on d/b-series.

[EGB18CT]

what about a 35r - its the physical size of the turbo bigger then the .82 3076? only reason i ask is i can actually get it cheaper than a 3076 :)

[Weq]

35R is useless on the street. no midrange.

dia-16t has it right.

[EGB18CT]

yeh, car will hardly be driven on the street. what potential has the 30r in a .82 got power wise and 1/4 mile wise. i want around 500 to 9-9.5rpm and run 10.5-10.7s

spoke to phil who made my manifold, said i prolly wont be able to fit a full rad with the 35r, 30 yes. but from some graphs i see the 30r starts to die up top to what i want to rev to.

hmmmm it sounds like a 35r will suit me better but if a gt30r can get me to run mid 10's then i think it would suffice whilst also enjoying some midrange.

[Weq]

you said you wanted mid-range? Did you not? If not, just go with a 40R. Less boost, more power. If its a track car u want.

[EGB18CT]

i think im going to settle for a gt35r .82, thing was initally i was going to build something for circuit, but have realised ill be more at the strip, plus the power and time figures im aiming for are not going to be circuit friendly. i've changed so many times myself its shitting me to hahaha.

From what ive been researching months on end, i was after something with 500-550hp, with the spool of a gt3076 (boost at 4-4.5k) but it would die off around 8k and would fall short of true 500whp. Plus some of the dyno graphs on evans-tuning.com and what mike of synapse has done were on hub dynos so read a tad higher than a roller which they seemed to get anywhere from 450 to 550hp out of a gt30.

The 35 can do it but it will hit over 500 easily but boost is at 5.5 - 6k.
I havnt been able to find something that has a nice sweetspot of boost at 4.5k and 500-550hp to 9k.

build as planned is:
Benson block to 83mm
cp pistons
pauter rods new bearings, oil pump water pump

port n polished head with valve job
supertech valve train
skunk pro1 cams

mite get driven 1 a week on the street (if that)

looks like ill end up with a gt35r what you reckon?

[Weq]

My opinion? THis is all talk talk talk.

[EGB18CT]

^make a bet hahaha, either gt35 or 3076 will be ordered within a week, next is a laskey block :) looks like ill go with the 35

[Weq]

But u dont have any goals? Wahts the point of this setup? Dyno queen?

[EGB18CT]

i want a setup that will satisfy me, that i can take it out to the strip most sundays and run consistent 10sec passes thats the goal, its just confusing as hell trying to sort thru a lot of crap out there that people claim that works when really it don't.

im not fussed in dyno queens thats why i want the best possible setup that will let me get to this goal - picking the correct turbo for the motor planned is vital that will get me the pass consistently, i have the sussy pretty much sorted, just getting some sperical bearings and all that put in. Engine internals, bore sizes and all are pretty much set in stone now of what i will get. Same as the drivetrain. Just this stupid turbo is bugging me!

anyway thanks for your input guys.

[DLO01]

GT35R, 0.82A/R. Done. :thumbsup:

[SLOWEGG]

GT35R, 0.82A/R. Done. :thumbsup:

Friend has that one his stock b16a.. LOL fun car..

[fatboyz39]

GT35R, 0.82A/R. Done. :thumbsup:

Yeah on a Stock b16a, it does go pretty well. Didn't it make over 170kw atw with that turbo kit?

[DLO01]

If its the one with the AFI kit they yeh 17xkw to the road. :)

[IEVAQ8]

umm..........i dunno why u need so much power to run 10sec passes........i mean yeh it will satisfy u not being able to keep the car straight lol............

example, a good mate of mine owns a 11.83 sec toyota starlet, it make 204kw at the front wheel, plus 30hp shot of nos..............

another mate has a tx3 laser front wheel drive, makes 230kw and runs 11.60 sec

another car that most of you know, is BLKCRX ran 11.68 at 121mph with 250kw.......b16a

so power aint everything...........weight and suspension is your key.

my opinion, if you had 300kw ur laughing with the right setup...........

good luck anyways.......id love to see this finished

[EGB18CT]

but tom, there all 11 sec cars haha im building some different to the rest of oz, im doing a US style of build, sleeves and all, this car i was eyeing ran 10.2 and trapped in the high 130's, and ran 10.98 on 15psi with a simiar build that i have in mind. should be all good. this set up wont be built over night, im just doing lots and lots of research as i dont want this setup to turn to shit, where possible the best parts will be used.

just going to confirm that i will be able to run the 35r with my mini ram with phil- my main issue will be the oil line return and maybe clearance, but i think it should all be fine.

[barefootbonzai]

Yeah on a Stock b16a, it does go pretty well. Didn't it make over 170kw atw with that turbo kit?


If its the one with the AFI kit they yeh 17xkw to the road. :)

18x kwatw @ 8psi on a stock gen 1 b16 woohoo! But yeah, it's a bit of an overkill, all top end powa!

[2MPRSS]

gt35/40 i think mine had a .71 exhaust housing u will shit bricks after 5000 rpm

i was told to use the 35/40 because my aim was everyday driven street car, that would liek to hit 10s in the future

[EGB18CT]

ordering a gt35r vband .82 :) tial 44mm gate with .8bar spring and a benen fuel rail to match my other benen goods :) should arrive late next week i hope :)

hehehe, hopefully i can keep my build under wraps now! gf's uncle is building 2 banger cleveland motors for his drag car, hopefully when im done i can suprise them at calder too

[IEVAQ8]

good work.................i got my similar set up together tonight..............

pics to come later..............

good luck with urs man

[EGB18CT]

just paid for my sexy garrett gt35r bb .82 v band housed turbo
tial 44mm gate and some more benen ind stuff ... benen fuel rail just had to splurge a bit more hehehe

next on the list a head or block and some shafts :)

then mfactory pro turbo full gearset and wave trac lsd for some happy time:cool:

[SLOWEGG]

Is gearsets needed? What gearbox is CRX11Z running if anyone knows..

[EGB18CT]

stock with strengthened case i think?

the longer it takes something to break the more fun i can have at the track! At the power figures im looking at i believe ill need them, although i think crx11z wasnt making much power as he has a very light crx, this was before the gt35r upgrade i believe??

well in fact ill most likely be gearing the car properly anyway, the gearsets are 2k US so not too bad compared to a liberty box, so i may as well put in a bit more now. anyway that will be purchased after the head/block so still a while away.

[Weq]

pre-loading is the key. And a clutch that can take it.

[2MPRSS]

yehh a clutch a must, i lernt the hard way.... KABOOOMMM

[EGB18CT]

hahaha, yeh, will either be getting a cc twin, tilton twin or act/exedy twin combo for it.

[SLOWEGG]

He was making over 500HP on his old setup..

[RICER23Q]

170kw on a 35r with the stock b16a? what a ****in nugget... why would you even bother with something so laggy when you're not even boosting it and getting shit power?

3076r, 0.63 rear ftmfw...

[EGB18CT]

gt35r arrived today with my tial gate and fuel rail :P

[IEVAQ8]

any pics???????????

[DLO01]

Nice man. Sounds great. :thumbsup:

[EGB18CT]

ill post some pics of the goods tomorrow or fri, my lappys gpu died (fault with dell m1330) this computer im on runs like dogs balls, so yer, i thought the turbo would look bigger but yeh overall very happy with it. Hopefully this dell tech comes out and fixes my lappy (not that i will trust it later on as they are a defect with the gpu and a replacement without the defect is not avail so kinda sux, gonna have to spend 1g on a back up i think so less for motor :( cut as ahahah

[EGB18CT]

here we go boys and girls... who's ready to play?! (something keeps bugging me to buy a gt42r and topmount hehehe) i think this should do fine for now, will be quite insane once done. Next on the list is the sexy short block

Threesome front end:

no turning back now :)

[IEVAQ8]

very nice catalogue....................hehehe

[dai-16t]

Nice but a Tial 60mm gate and V-band stainles rear housing should be in those pics. lol

[EGB18CT]

twin 44's may be on the card later on, but for now it shalt do! as long as it does the job!

[DLO01]

44mm is perfectly fine for you application.
http://www.evans-tuning.com/techarticle_wastegatesizing.html

[EGB18CT]

it should be all fine for the boost i want to run, now for the shortblock

[ILZ]

Is gearsets needed? What gearbox is CRX11Z running if anyone knows..

i run a stock ls integra box

[ILZ]

stock with strengthened case i think?

the longer it takes something to break the more fun i can have at the track! At the power figures im looking at i believe ill need them, although i think crx11z wasnt making much power as he has a very light crx, this was before the gt35r upgrade i believe??

well in fact ill most likely be gearing the car properly anyway, the gearsets are 2k US so not too bad compared to a liberty box, so i may as well put in a bit more now. anyway that will be purchased after the head/block so still a while away.

i made 401kw at the wheels (537hp) before the gt35r and cams.

[EGB18CT]

sounds good hopefully i can hit close to 600hp fully built with either cams like the skunk2 pro1's or something like spec 3 buddy clubs etc, wont get the short block for a while as the $$ has gone shithouse.

what you doing powerwise with the 35r now?

[ILZ]

cant get a power reading, come up onto power suddenly and get to much wheel spin on the dyno- neva got a decent hp reading yet. maybe put it on a dynopac hub dyno and see what happens.

you aiming for 600 hp at the engine or wheels?

[EGB18CT]

550-600 at the wheels would be nice, the motor will be built to support it, then those fig would prolly be on a high reading dyno, goal is a low 10 with 9s on the cards try crack that with the 35r

[ILZ]

good luck! i hope everything works out for you!
running sub 11.0 sec times in a turbo fwd isnt as easy/cheap as you might think... i have spent well over $70,000 on mine and years off research and development to get it runing 9z.
take a look at rob the backyarder with the corolla- dogbox/nitrous/wheelie bars/28x10.5x15 slix/11,500 rpm... been at it for a few years now, spent atleast $80,000 and runs high-mid 9z on a good day.
but i hope you reach your goals!:thumbsup:

[ILZ]

what management system are you going to be running?

[EGB18CT]

most likely going to go with aem, as im also thinking of running a t1 hall sensor and cop eliminating the dizzy, but its very $$$, hondata wont support the cop/hall i believe, and the aem will have ignition cut which will come in handy with the mfactory gearset im considering.
