hey guys bought my new setup and was wandering if my goals for this setup are worth hoping for or not. also havent decided on cams yet, going to be gsr,itr, or ctr just havent decided yet probably gsr because i can get a set cheap.

going into my ej2

setup:
gt2871r .63 a/r
lovefab mini me eq manifold
38mm wastegate
tial bov
3in exhaust all the way back
precision intercooler
GSR motor
weisco pistons 81.5mm comp will be 9.7-1 after everything is assembled
eagle rods
stock crank
skunk 2 springs retainers stock valves
blox intake mani
70mm tb
750cc injectors

also it will be tuned by dave at whip

it has a 9lb spring at the moment

i dont think im missing anything. mostly looking to break into the 11's and i figured anything over 300whp should get me there. ill most likely be running a slick at the track.

any opinions appreciated

for only 330hp id get a 28rs instead of the 2871.. the 28rs will make htat power easily and spool a good bit faster than the 2871

duckmanEG

He already has the turbo and everyone knows how a turbo is. 330 is a starting point. So im sure even if he says no. He will up the boost down the line.

a buddy of mine made 295whp 210 tq with a 2871r (.48 a/r) on 13psi on a stock block b16.

330 should come easily for you mang.

I believe that 330whp should get you into the 11's depending on how you hook up. Although it's not a **** load of power if you can get traction then I believe it's doable. Is the car gutted or anything if so that'll definitely get you there. For reference I used to know of a guy with an Si built motor making approximately 370hp he made it into the 11's no problems I think his estimated time was 11.5-11.7's in the quarter. You do the math. But F that gt2871rs thing get a bigger trim more room to breathe in the future.

on the Vw 1.8ts with the .63 housing and an internal gate the 71r only spools up about 300rpm later to 20psi and will hold boost better on the top end then the RS will.

People regularly do 290-300 to the wheels on pump gas running about 18-19psi.

If you didn't have the stuff already I'd even say stick with an internal gate on that turbo. I've done probably 10+ on 1.8ts and they run perfectly.. Its actually the ideal setup since it gets you the quickest spool up of a turbo that will just touch the limit of the factory rods if you tossed in some 104 but is perfectly safe for daily driving.

a vw is a bit different than a honda...

overall spool isnt much slower but response is ALOT slower.

An engine is an airpump.. if you go super generic and ignore timing and valve timing/lift an engine of the same displacement will move air at a similar rate.

Given that he is using an engine of the same displacement with a head that flows better then the small port Vw heads and using better tuning then the generic chip software that people use for the 1.8t with this size of turbo he will have no problems spooling it.. which you said.

the response time difference is almost non existant between a 28rs and 71r.. That doesn't matter what kind of engine its on.

he is running a higher CR then the stock 1.8ts come with which are actually lower then what they are rated for.. really like an 8.9:1 not 9.3:1 they claim.

His spool time and response time will actually be better then that of the VW.

Yes the vw engine and the gsr engine are different engines.. but that doesn't eliminate basic science of what an engine is.

the 71R and RS are still tiny turbos response time is not something I would worry about with either.. What is your definition of response time so that we can make sure we are talking about the same thing..

Are you talking about how quickly it will come back on boost after a shift or rolling onto throttle in a higher gear?

If thats the case.. then response time can't even be easily measured because its almost instantaneous

crawlin

well like duckman said i probably will up the boost but not for a little bit and i probably will try to have a track tune and a street tune. i just want to hopefully break into the 11's with this setup and then up the boost if needed after all it will be a built block so no worries hopefully.

no the car is not gutted and i will not be gutting it

yeah the setup is already set in stone i wont be switching the turbo anytime soon next turbo i get ill be aiming for 10's not 11's.

keep the info coming

oh yeah what do you guys think about cams? itr ctr gsr
