GT2871R a/r.84 questions

[LANOI]

Ok I was wondering would the gt2871R (Gt-RS) be able to produce a range of poweer from 500-600 an up RWHP ??? or should i pan to get bigger turbo for this range. I also plan on getting the upper block redone cams, rockers, stoppers, ect. what would the bottom half need under this kind of construction i wanna do? I want to get a lower mileage s13 redtop engine so everyone knows what it going to. purpose of the car is a decent ride home, basically (street, drag, no crazy timelike 9sec, id be happy with 11.5 or any 11sec really) A to B. thanks for all the help everyone i if u post.

500-600 with a GT2871..??? No way in Hell man. At least a 3071 if your looking for anywhere NEAR those numbers. Personally i would go GT3076, take a look at the twin scroll numbers by Full Race.

455whp @ 22psi is the most ive seen from the 2871R .86. That wasnt the GT-RS 52 trim though, it was the standard 56 trim. Fresh Alloy has the dyno.

455whp SR S13 will trap around 125-128mph in the 1/4 which is good for mid-high 10's with a 1.5 60ft start. The start is always the hard part.

Couple of my friends are hitting those numbers on the gt35r. If u go divided inlet on that it should spool relatively quick at top end is F@$#in' BEAST!!! All depends on where u want/need your power. plus good luck finding a gt35r divided inlet from garrett., that thing is on 3 month back order

what is a divided inlet?

[DrifterProdigy85]

Divided Inlet is where the Exhaust Housing has a Divider inside used to increase exhaust velocity giving more tq across the powerband. Only way it works though is by running a Manifold that has the Runners split to match the split of the divided housing. You match cylinders 1+4 together and 2+3 together on the SR. Another name for the setup is Twin Scroll.

Ill be running a T67/T4 Divided Setup on my SR next year hopefully. Itll give the same midrange as my 2871R .86 setup but give near 700whp @ 30psi at the top end.
