keep changing my mind. gt2871r .64 or .86

[idahotuner]

i keep changing my mind and it stresses me out lol. i get my mind set on the .64 cause of more low end torque incase i ever want to try drifting and for the quik spool up, but realisticly i will probly only ever drag race. and have it as a weekend car so why not have the .86 and gain some extra hp. i have read all the forums that i found with the search button about it. and at the end of one i am like ok i am getting the .64 and then i read another one and i am like why not get the most p for the money and i want the .86. so a little help deciding would be great.

and i am sticking with one of these two so please no other suggestions

[idahotuner]

one is a .64 will only give 375 whp max (i have read about the kid getting 400whp with this turbo)

they cost the same

the .86 will give about 420 whp max

.64 has more lowend torque

.the .86 has more highend hp

.64 spools fasterwhich means power sooner just not as much.

the .64 is more for drifting

the .86 is more for drag

i want to be able to drift eveyonce in a while

but i want to be able to kick *** draggen

i keep going back and forth and it sucks

i want to get 400 rwhp which is do able with both turbos, and with that hp goal i want as much torque as i can get with 400 hp. will the .86 give me more or the .64

i had that one guy just has his .86 dynoed and got 350whp an 358lb torque so it seems liek i should be able to get 300 torque and 400 hp right.

[idahotuner]

oh the only competing i will be doing is drag racing at the local track.

[srdub-t]

get the .86 a/r for drag because the extra lag might give you a chance to hook your tires up and then rip past you opponent. The lag shouldnt be that bad

[PhopsonNY]

You could get the gt2871 with the t3 option.

You could also get cams

[idahotuner]

yea i got 264 cams

[idahotuner]

bumping my question

[S14toRPS13]

Reminds me of my debate with the t3/t4 turbo too. But I'd say go with the .64 one. Sounds like you'll be driving this car on the street a lot more than at the track and having that instant power is more useauble on the street.

[srdub-t]

na .86 definatly its not like its going to be super laggy. Your still gonna hit full spool before 4K and with a high reving motor that perfectly fine. Thats just my opinion

[idahotuner]

dang. you guys arnt able to make your minds up as much as i am not.

[ILikeMy240sx]

.86 with cams can be pretty laggy.

For example, my .64 with 260/270 cams boosts at 4500 RPM. Before cams it was 3500 RPM.

So expect the spool to be around 4000~4500 RPM.

[idahotuner]

yea. so with my 264 cams and a .86 should perform pretty good right. and have some good power.

[ILikeMy240sx]

yup... get the .86... If you dont like it I will swap out my .64 and we can trade :-)

I wish I had gotten .86 to flow more at high RPM where my head has the capabilities to flow but turbo can't follow....

[idahotuner]

sweet you got your self a deal. wont know if i like it until next spring because that is when my project will be done.

[ILikeMy240sx]

haha my 240 will be gone by then... Im selling it to get my self a C5 vette. yummmm

[idahotuner]

sweet sounds like fun. hopefully you will still be on here to answer all my questions

[DrifterProdigy85]

Youll like the .86. I used to have .64 and then bought the .86 housing and swapped it on. Feels much better. A much more solid pull. Just have to make sure you have the supporting mods for high rpm. Like Tubular Manifold, Greddy Intake Manifold, Large Turbo Elbow, and 264 or 272 Cams. With Power FC guys are hitting 450whp with the .86 2871R now. Tuning plays a big part as well.

[idahotuner]

greddy intake manifold. i am sticking wit the stock one because i heard that the longer runners gave more lowend torque.

[ILikeMy240sx]

you are correct. Greddy IM does sacrifice quite a bit of low end torque for a bit of gain up top.

However, I think with a bigger turbo like .86 gt2871r or above, you should really shorten those runners and make it easier for your turbo to flow more at top.

I guess it really depends on what you are doing. If you are into auto-x or road racing with lots of turns Id stick with things that give more low end torque.

If you are more into drag racing or highway races... you need to focus on high-end power.

[idahotuner]

you dont have to get a retune when changing intake manifolds do ya.

[karmakaze]

i had the .86 and i was quite happy with it.

[idahotuner]

SWEET this month i am getting my apexi intake and some turbo extension. and i will finish paying off my car. so then next month i can get my turbo and injectors.

[ILikeMy240sx]

You should put my name somewhere in your engine bay for all the questions Ive answered for you ;-)

[idahotuner]

YEAH i was thinking about something like that. maybe a windshield banner lol. that could acctually look cool. i will see waht i can do lol.

[DrifterProdigy85]

Also you should get a retune when changing manifolds. My original Enthalpy tune ran lean after i added the Greddy Manifold so i got a retune and it was perfect again. You sacrifice alot of top end power staying stock manifold too. The top end power is the reason you go .86 over the .64.

[idahotuner]

well i nmy sig you see my upgrades to my head. is that enough for the .86 i dont really want to change out intake manifolds yet. how much is it to send a rom in to get it tunned again, is it 500 each time.

[ILikeMy240sx]

its about 100 a retune... I cant remember the exact amount but thats about how much it cost me after cams. After that retune people cant even tell that I have cams because Enthalpy smoothed out my idle so well.

[DrifterProdigy85]

$125 for retune from Enthalpy. My 270 cams idle pretty smooth too. They sound rough when coming to idle but smooth out quickly.

[DrifterProdigy85]

I was around 360-370whp on stock intake manifold and once i upgraded to the Greddy it was a world of difference. Car kept pulling at whatever RPM. Didnt take much to top out 5th gear after that. My guess would be around 400-405whp after that. Never got a chance to dyno cause my exhaust manifold cracked a few months after that.

[idahotuner]

yea i want between 375-400 whp. want to run two boost setting the lowest boost the turbo can do and the hihgest boost. . when gettign a greddy intake you have tochange so much stuff on the intake and make sure pipe hook up right. and intercooler pipes. i think will wait and if i dont like it then i will get the greddy.
