sr20 turbo upgrade!?!

[keMz]

i was going to buy the turbo upgrade kit off FRsports.
FRSport T28 Dual Ball Bearing Customizable Turbo Kit for S13 SR20DET (http://www.frsport.com/FRSport-T28-Dual-Ball-Bearing-Customizable-Turbo-Kit-for-S13-SR20DET_p_7971.html)

just curious on what the differences in the turbo options..
was just going to go with the s15 turbo or w/e but was noticing that it maxs at 320hp..

just wanted some other angles on this matter before i order it..

prolly lookin at next tues or so when i place the order..

thanks guys (im noob, so give me the run down in english)

[keMz]

oh yah..

setup:
rebuilding sr20det redtop
pretty much stock head
built block
pistons 9:1
rods
ACL rod / main bearings
APR studs
greddy oil pan
new oil pump
new water pump
new timing chain kit
koyo rad
flex fans
a/c
current setup:
ARC bov
ARC smic
but was gong to upgrade:
hks bov
greddy LS fmic

still trying to find a greddy intake setup.
my overall goal is to get some kind of e-manage and tune it to 315rwhp+ in the end.

Was going to run ARC setup for the first few 1000 miles then get the fmic and hks setup and go big =p but wanted to purchase this turbo upgrade now for the reason that i spun a bearing due to low oil or thin oil and i think i damaged my stock t25 turbo.

any input is cool guys..

idk some people told me the ARC setup can handle more than 1 bar.. which that is like 15psi??? i wanna eat sti's alive with 1 turn of my boost controller pretty much.

[keMz]

i was going to buy this kit, just wanted to know everyones take on it..

FRSport T28 Dual Ball Bearing Customizable Turbo Kit for S13 SR20DET (http://www.frsport.com/FRSport-T28-Dual-Ball-Bearing-Customizable-Turbo-Kit-for-S13-SR20DET_p_7971.html)

was going to compare the different turbos options i have and whats the best one to roll with.. i want to be able to hit 300rwhp+ eventually..

ima just run ARC bov with ARC smic until i put a nice 1000-1500 miles on the fresh motor.. then i was going to run HKS Bov with Greddy fmic..

how much can the ARC smic handle?

just want to know whats good and why.. maybe some personal experiences?

thanks fellas (im a noob with this turbo business.. but yah)

shorten that list down to this.

z32 maf.
tomei / BC stage 2 cams.
550cc injectors.
garrett gt2871r.
ss turbo lines
ROM TUNE.
greddy headgasket ( ...or decent brand besides cometic )

if you have an fmic good... if not, fuck it. as long as you have no leaks... and your gaskets (intake/exhaust) are good. only buy and install the things on that list.

* my opinions *

EDIT:: this is a 400hp build - more worth your money, rather then doing it twice.

[GSXRJJordan]

If you want ~320hp, get the S15 Spec-R turbo - it'll be cheaper than a GT2871R .64, which would logically be the next step larger.

A front mount will help you when you decide to bump the boost, but that ARC sidemount was designed for ~300hp, so it's aiight.

[waynehead05]

The 2860rs is going to top out at 330wheel pretty much. The 2871 has been shown to make 385 to 400, but it all depends on other things.

What's the most power you want to make? What are you going to use the car for? What type of power band do you REQUIRE?

ROM tune?..

everything else on that list can happen.. prolly going to get tomei pon cams if not run stock..

so basically your saying go with the 2871 or the s15 spec r turbo..

would i want the .64 or the .86??

sorry but dont really understand fully..

the .64 will spool/boost faster but have less max hp? (380+?)

[S13 curtis]

GT2871r .64> then both.IMO
Fast spool, way more power, you can't beat that

and if it were GT2860RS or or S15 T28 i would pick the S15 T28 because the price is way Cheaper then the GT2860RS and the put out close to the same power.

[sunnys14]

GT2860R = S15 turbo (320whp maxed)
GT2860RS = Disco potato (340ish whp maxed)

[Def]

GT2860R = S15 turbo (320whp maxed)
GT2860RS = Disco potato (340ish whp maxed)

The S15 turbo is actually a GT2560R. It's turbine wheel differs from the NS111 found in the GT28xx turbos. It's a 53 mm major diameter vs. 53.8 mm major dia. for the NS111. The trim is also smaller, so that means the S15 turbo has a smaller exducer too.

I'd say in a RWD application the max power you can really expect from 90% of the builds with them would be about 310 and 325 rwhp as they're very alike when you get down to it. In FWD applications I've seen higher power with them due to lower drivetrain losses.

[4x4le]

A rom tune means a retune on the factory ecu, which is a better peice of electronics than say.... emanage.
Emanage is a piggy back and your just altering the ecus signals.
A rom tune is the factory ecu, only retuned for the new setup. When you retune the factory ecu, it is like the factory ecu was meant to controll your current setup like it came from the factory that way.

[JeremyR]

gt2871r .64
740cc injectors
z32 maf
apexi power fc standalone

should be good for 350. this is the setup im building right now actually.

thanks bro,

so either i stay small and go s15 spec R turbo, or go big and grab the t2871

im leaning towards the t2871 only because its a little bit more money..

should i go with .64 and .86? now too quite sure, but i see most guys with the .64, any input here?

[Def]

I'd go 0.64 a/r. The few hundred RPM is more noticeable in more situations than the ~20-30 rwhp the bigger housing will make up top with the boost cranked.

If you are really into going as fast as possible with a bottom mount T25 flanged turbo, then go with the 0.86 for a bit more power in boost.

good call..

how would u compare the power fc from a greddy e-manage?

[g-via]

standalone > piggyback

as stated above.

[keMz]

standalone > piggyback

as stated above.

so im taking stand alone is easier to setup than a greddy eman?

[cc4usmc]

Not easier, more...efficient? I'm not sure if that's the right word to use.

hmmm so .64 is faster response but less top hp.. vs the .86

no that just means that emanage is a piggy back which is worthless in the first place.

[Def]

Yes.

msg length

[kalypso123]

standalone's are lovely if you can afford one. and you can always use it on other builds, or sell it if you do something else...

APEX'i POWER FC is a standalone, and enthalpy would be a reflash/rom tune... iirc

I never dabbled with megasquirt, but I should learn myself.

[S14DB]

You only need to make 1 thread about your question. Just update it as you change your thoughts.

[S13 curtis]

no that just means that emanage is a piggy back which is worthless in the first place.

not true, i run an e-manage and it works fine and im sure it can make the same power as your rom tuned ecu. and if i need to change something i jus hook up the laptop and not have to send in a ecu with 125 bucks and wait 2 weeks for it. i can also tune to run E85 and others. E-manage to me is the best bang for the buck for mild power tuner. and if you wanna say the e-manage sucks you can also say the SAFC is a bigger POS.

[JeremyR]

i bought my apexi power fc w commander used, with a tune for the setup im going to run, for 600 shipped. so in that case its definatly worth it. whats a good ecu re-flash go for? 400-500?

you cant dyno tune a ecu reflash (well, easily, anyway)

a standalone is a shitload easier to do dyno tuning with. which i always recommend ANY time you mod a car. especially when you're messing with the a/f ratio.

[lazysk8er2]

i havnt heard good things about the emanage. i cant knock it cuz ive never tried it:tardrim:, however ive been learning more about nistune and it has great potential. its has the same effects as the emanage and stand alones but its a daughter board ecu thats adjustable on the run? not sure how to explain it. anyone wanna expand on that?

try this link
http://zilvia.net/f/chat/235517-nistune-results.html and he uses the s15 turbo

welllllll SAFC is a bigger POS........

[4x4le]

lol, yea, Im sorry. I should be more carefull on how I state things because Im not trying to make people mad by saying things about peoples current setups, but im not going to try to let people make the same mistakes with purchasing piggy backs just because others have done so in the past as well.

There are many options you can go with as far as rom tuning where you no longer have to send them and pay 125 for a so called retune. I dont think it should be considered a tune unless it was make for your car, while actually performing the tuning on your car.

what exactly is this turbo..

but looking at it.. id say it was a Garrett GT28R......

when i see GT2871R and GT2860RS, im confused

just having a hard time deciding which one to go with.. ofc

thanks

im thinking the power fc is the best way to go =p

[Mr.GT30]

Question is how much power you want, and how much money u want to spend, GT28bb, 270-310hp.gt2860 aka disco potato atmost was 340hp gt2871 up to 410 base on what gas and application on ur motor,,

so the s15 spec r is gt28bb?

prolly will be going with the gt2871r

[smelly240]

the s15 turbo is a gt2560R. goto their site for info.

You don't need to make a separate thread for every turbo. For the second time...

sorry sir, last time i swear

you need a nice mani and outlet to go along with it :)
