turbo upgrade on apex need input

[boost mod]

have 19-t rear mount looking for faster spool will be running 17-18psi and i have a boost it controller so i can adjust for any turbo or so i understand.
what is the best turbo out there ?

GTX2860 or GTX2863 sounds like either one would work well for you.... Either one of those should spool a lot faster then the 19t from what I have been told and plenty enough for that boost.

The 2860 will be pretty much maxed at 18 psi though. If I were you I would go with a 2871.

these are what you want,the gtx2863 should spool a bit faster than the 2860 & have a little more top end than the 2871.or you could get a billet wheel for your 19t.

The 2860 yes but I beleive the GTX2860 will push a good bit more. The new billet wheels are very efficient and don't seem like they ever give up on top for a small turbo.

Thanks for the info had a look at the gtx it's definitley a improvement over the 19t has anyone got one of these with a twin scroll and still used a 4 into 1 exhaust and put a quick spool valve on?
this is popular with the import 4wheel drive cars because with the added bottom end power they can still put it to the ground.the acura RDX uses the same thing from factory.they say it spools like a turbo half its size and once the valve opens then it's still able to make the big top end power.

I think those are for spooling big turbos. You dont need one for those size turbos I don't think your gonna gain much. Those two turbos should spool lighting fast

My turbo is a rear mount and i want to keep it that way but i would like the fast spool up of a front mount.You are right they are using them on big turbos but there redline is 6500 rpm and they are noticing a 750rpm drop in spool up time. apex redline is 10500 rpm so it makes me wonder what affect it would have.if i remember right my boost is not at full boost till after 8500rpm+. what is it on a front mount with a good turbo?

very cool idea it would help but you would prob not see as big of gains as the do with the bigger turbos.head porting & cams will help spool up allot if thats what you are going for,my nytro spools my big 4inch 2871 like nothing

 

[tjc]

give it a shot, you wont be able to port the head and do cams for $250.00. you never know til you try it.

Move the Turbo ahead as far as possible......it will spool plenty fast enough.

yes i have no doubt you are right that's why all the big power kits are built that way. but then it opens up other problems and cost tank,water to air intercooler,more heat in engine compartment, a lot more weight up front.

I meant move it forward approx 12 " from where it is now. it will fit and spool very fast. Locate it just behind the tank and work over a seat to house it.

what is the max boost of a 2871 on an apex before it's not efficient?

This is the mod that Randy is talking about.

It is relavant to elevation. At low elevation a 2871 will live in the low 20's for boost no problem. It's when the air gets thin and the turbo has to work hard to compress the air the troubles start. The other issue is the charge systems ability to cool the air. Beside the 2871 will be lazy in any rear mount application, and especially at elevation.
I would say go 2867 GTX and get the best of both worlds. Problem solved.

I have some 2863's on order and can order a 2867. I think they are about the same price, but the 67 will flow more on the top.
