d16z6 motor

block:
9.1 compression pistons
scat rods
darton sleeves

cylinder head:
1 mm larger intake valves
polish swirl intake valves
crower valve springs
crower retainers
crower cams
port and polish head
port and polish intake manifold
rpm 68mm throttle body
aem cam gear

my current turbo set up:
equal length manifold
turbonetics t3/t4 turbo
2.5 inch intercooler piping
drag fmic
750cc injectors
3inch downpipe
3inch exhaust

this has been discussed many times for the d16z6, but im looking for a little over more then the 340, which the gt28rs can only put out. but what will be the difference in spool time? since i have a fully built motor, would it be wise to go get the gt2871 since its one step above the rs? who are running the gt28rs or 2871 with their SOHC's? what will be the difference in spool time? when are you guys hitting full boost with your sohc with these turbos?

bump someone must have some experience

well after all my research I made the conclusion that the 71R will spool like 500 rpm later than the RS and will get you full spool at around 4200rpm or so. Do not forget that the powerband wont be the same at all if you compare it to the RS. The RS have a sick midrange and a decent top end ( it will have the same torque than my SC50 at 7500rpm but it has close to 45lbs more at 4500-5000 )

Do you want 340whp on pump gas ? If its your goal go with the 71R... the RS wont do that for sure....

Are you gonna use the car on the stret or on the track ? Ive seen many D16Z6 that were close to 300whp with the RS that were running low 12's... it depend on your goal. Geoff from Full-Race told me to go with the RS with no hesitation... thats the turbo he will install on his D16Z6 too.

BTW im supposed to get my RS .82ar today eheh so go with the 71R and we will compare our results !

anyone else?

Bump cuz I would like to know myself. My frustration comes from telling myself that if I have a built motor, I am going to want a GT30r eventually. For the people that have the RS and 71R...how is the traction on the street?

beerbongskickass

Try a gt30r and let me know how it goes.

On a D16? Bah.

I think that if you're going for 350whp on pump gas reliably, GT2871R

you mean the .86?

Here is how I think of it. The rs is a very nice turbo that spools quick and puts out good numbers for the size. My thought is if you want big power buy a turbo that wont miss (such as a gt30r) if you want midrange quick power go for a RS. No need/reason to go between the two IMO.

Well this guy's motor is built pretty solid... might as well go big and not *** around.

i had the gt28rs but i outgrew it, the powerband is amazing but ti did start lacking from 8k+ at higher psi's. I am gunna get a gt30r i think and hopefully i dont outgrow that lol

True.

LilCivic04

i guess i can sacrifice some midrange for some crazy top end, what kind of a/r should i be going with the gt30r? when do you guys think i will be hitting full boost by?

beerbongskickass

Well with your goals a gt28rs would work pretty well. If I wanted 300-350whp I would defintely go with a gt28rs, but I want more like 300-350whp daily and 450-500whp at the race track, so the bigger turbo would work better for me.

nah the .82ar is a T3 housing. Made to fit the T3 manifold, bolts flanged downpipe.

BTW I just got my GT28RS .82ar an hour ago by FEDEX. Its sooooo small compare to my SC50 .63ar lol its also lighter.

Personaly from my experiences a too big turbo for the street is not fun at all... the power comes violently after 5000RPM so there is no way to shift earlier to get traction or you will loose all your boost.

With my first Greddy kit the turbo was reall too small but it was really fun and fast... the SC50 was a too big but fast too. Im now between these two turbo with a really efficient turbo that gives a lot of response and a huge powerband. Personaly I like a well balanced car and even at only 300whp its a lot for the street.

I cant wait to summer !

I cant wait for someone to try a GT30R. Rota92 with his GT35R said his turbo was pretty good on the street....just imagine the 30R? HHHMMMM

LilCivic04

was he using a d16?

LilCivic04

ok, has anyone use a gt30r for their d16? i mean when does it hit full boost by???

Yes a Z6

You should see what he will be going to now Ill let him have the privilage of telling people though, not sure if he has let the cat out of the bag to many people yet.

I might be trying a 30r soon. I was going to get Rotas 35r but ran into a few small things and had to rethink the plan.

YellowTurbo:Yeah I always forget the t3 housings

LilCivic04

hella_jdm had told me taht he hit 9lbs of boost by 3000rpm on his gt2871r 63.ar

LilCivic04

i've decided to go with gt2871r 63. a/r

dornon13

be sure to post results very good information here

LilCivic04: I run the same turbo. pulls hard past redline, no doubt. My old setup had bad manifold leaks though so i got fullboost real late. I'll let u know how it goes when i get it fixed up.

Personally i dont see the RS supporting over 300whp. tht thing is real small. The smallest id go for 300+ allday is the 71r.

there have been plenty dyno runs showing the 28rs making 310-340whp on b18's...

Weq

and i bet it could make 400whp on a v8. this thread is about d16's. The flow rates just dont add up. Its only rated at ~350crank by garret also.
