Well i just recently ditched the old turbo setup, and ran into a problem while uninstalling it...quite a story actually, first the tuner toys oil fitting broke off in the threads. so i go get a bolt extractor and IT breaks inside of the TT fitting lol. so now im really pissed and dont really know what to do. the solution i came up with was to buy my buddies GE oil sandwich adapter and run the oil pressure switch into that (yes i know the threads are technically wrong but i didnt care. so got it all together and it worked fine...dripped a little oil super slowly..so a couple weeks later i am drivin along and decide to pull 1st-2nd (dunno why lol stock y8= gay) soon as i hit second i hear an awful clank. turned out i tightened the GE adapter on too tight and cracked the threads and the block..(i remember hearing it pop and praying haha) so now here i am rebuilding the motor and im just doing the normal pistons and rods with wisecos and eagles.

so here is my motor so far.
D16z6 bottom stock sleeves
wiseco pistons gonna give like 8.6:1 CR
D16y8 Head stock
ARP Headstuds
pro cluth stage 3 clutch
8lb flywheel
y8 tranny
oem diff for now. hopefully upgrading with the turbo

heres the planned setup(minus turbo)

tial 38mm WG
tial BOV
home made Equal length manifold ( i plan on doing alot of research to make a bangin mani. i am very interested in manifold theory)
either 680 or 1000cc injectors
greddy profec B spec 2 EBC i want to upgrade this to something with gear or speed dependant boost.
plx m300 wideband
neptune if it gets released by the time im done. otherwise crome untill then
3" downpipe maybe 4" if i make a topmount
DMH cutout do they make these in 4" lol
prolly need to get a FPR
the avg gauges prolly boost/oil pressure..possibly egt
ditching the pcv system probably putting bungs in the valve cover
jrc 6" intercooler
2.5" IC piping

so theres my list with plenty of un-needed info

Finally here is the question. Im trying to decide on a Turbo for my goals. I really really want a GT series if at all possible but if not i will have to just get a t3/t4. Basically im looking for people with a GT2871R or a GT30R on a D16 i am interested in the spool as well as the numbers. so far all i can really find is "get a BB they spool so fast!" i want to see real numbers.


Thanks for looking sorry so long. Here is a pic of my broken block....er maybe later we-todd is down

350whp on pump gas is going to be a stretch for a stock head. The sohc head only flows around 400whp, after that its just a big restriction.

300whp yeah, you can do that. 350? eehh i dont think so, not on pump gas at least.

cmon boostin you know im lookin at GT series lol

Liam thanks for the input thats pretty much the kind of info im looking for...anyone else?

Well then go for a GT2871R .63 a/r.

That, plus a Zex cam, valvesprings, retainers & ported head = 350whp on pump all day long

dornon13

when i get into the head i want to be able to go higher on race gas...the number in my head is 500 although im a little hazy as if i really understand how much it will take...thus the 30r being in my list haha

Quad-Damage

DMH cutout do they make these in 4" lol

they make a 3.5 inch now

Depends on the gas, pushing 350whp on 91 octane is a stretch. 93 or 94 you could pull it off maybe, and im talking maybe. I dont know if a gt2871r would be big enough for baller pump gas numbers like that though.

I dunno about on a stock head, but it's probably possible with a sick *** ported head with all the goodies. Check this link out... 325whp at 18psi on pump with a gt30r... http://forums.evans-tuning.com...=3145

seems like that guy needs to rev that out a little more no...?

maybe i should lower my goal and go for 300 now and try for more when i can work the head some.

looks like that gt30r spools a little later than i would like and thats the smaller one isnt it? I was hoping to find something that would spool 4500, 5000 being the latest i could handle... im starting to think its going to be necesary to work the head and rev it out pretty good

so with that said. whats the highest to be expected out of a 2871r on a d16 using c16 or whatever. i think i will end up going with that try for 300whp on pump/stock head...then work the head and add race gas for whatever it will throw out, hopefully between 4-500?

this should be a little more fun than going for the avg everyday 500whp DOHC

Thanks for the info keep it coming...if you have one of these turbos PLEASE chime in!

beerbongskickass

Well Jeff said the torque carried all the wat to 8k in that post, which is pretty good and it was fully spooled a little after 5k, so that's not bad at all if you ask me. With your 500whp goals your probably going to need a bigger turbo like the gt30r or maybe gt35r and just sacrafice a little spool. I doubt a gt2871r would get you there on a d16. Our motors defintely aren't as efficient as the b-series motors.

dornon13

well i think im gonna sacrifice the power and stay with the gt2872R can anyone tell us how it spools on a d16 from experience. also now i have to choose what AR i want to go with..i do at least want to make 400 on race gas

beerbongskickass

Spool is overrated...

dornon13

it is when you only got so muh rpm to work with

gt3037 is the med sized gt30r.

This is more or less the limit of these gt turbos...(not saying you could push them harder, but its when the turbos start pushing more hot air then anything else...

gt28r = 300whp
gt28rs = 350whp
gt2871r = 400whp
gt3071r = 475whp
gt3037r (ie gt30r) = 550whp
gt3040r = 600whp
gt35r = 650whp

Take your pick. How much power do you want to make? The bigger the turbo, the lagger its gonna be.

Lowering to 300whp on pump gas with a stock head is much more reasonable. I dont you you could hit 500whp on the 2871 (see above). You might beable to push any of these turbos another 50hp, but you are just working them really hard at that point.

If you want better spool, and must keep the d-series, id recommend making a 1.8litre with lots of headwork. Or upgrade to a b/k/h series motor.

upgrade? NEVARRR!!

These would be about the limits with a b-series correct? I would imagine the limits would be a little lower with a d-series motor.

Eh, like i said its give or take. With a really nice d-series setup im sure you could hit those numbers...but generally speaking yes the numbers should be lower because its going to take more boost pressure to hit any of those numbers above then it would be with a larger b-series motor.

what do you guys think about the gt2876 on a sohc? ive had my eyes on that turdbo for a while. I think it would be apretty safe bet for a mildly built y8.......

Why cant they make a turbo that spools from idle to redline and supports whatever power you want?!?

dornon13

become an engineer and design one for us. im sure its something simple
it would be so sweet to become a turbocharger engineer after i graduate! we have a class at my school on turbochargers somethin or another...to bad its a grad class.
