Swap Question, should i upgrade my turbo now? or later?

[Night_Stalker]

so i am almost done collecting parts for my SR swap, i have a couple of things that i am putting in with the engine, and i am wondering if i should upgrade my turbo with the swap, i figure my choices will give me a big enough increase from the stock SR that i wont feel the need to upgrade my turbo yet. if i do, now or later i am thinking about the Garret 2871R - SR20DET Drop in replacement. i am still looking into it to make sure it will work, it looks like i only need the s15 turbo piping adapter kit for the s13.... i know its probably overkill for my stock internals, but if i dial it down a bit it should be ok until i get my engine guts up to snuff..... but anyway, going in with my swap is a set of Easy Cams - Tomei, I think (got a deal on brand new ones from a guy at the tuner shop, still in the box. i dont know thier specs), 3" Cat-back Exhaust, 3" test pipe, 3" Circuit Sports O2 elimination downpipe (downpipe and turbo elbow combo, with an oval bottom that sits flush with my under frame), Megan racing manifold (if i do upgrade my turbo i will probably buy a JIC), Greddy Spec-M FMIC, an HKS Racing Suction Intake Kit, and a Greddy E-manage ECU.... thats about all i can figure that would affect the power... obviously, its not all thats going in with the swap...... but it's all i figure will affect the power..... maybe the carbon lsd will be relevent.... carbonetics 2-way for the VLSD punkin... if i can source one... having issues.. if not KAAZ 2-way.

but anyway, back to the question at hand. i dont know how far over the stock 205ish hp and 203ish ft/lbs my accessories will put me but i ballpark high 2s.... but honestly, i have no idea.... if anyone could hazard a guess, and give some feedback on wether or not i should upgrade my turbo now, with the swap, or if i should wait until the thrill is gone and then do it.... my suspension is already done All fully adj. links, Adj. LCA's, Sway bars, Tower bars, bigbrakes on the front (matched pads on the back) and wheels are 17x8.5 215/45R17 in the front and 205/45R17 in the back except for the Stance GR+PRO Coil's that are going in in the summer, when i take my winter tires off.engine bay is getting stitch welded during the swap, so my chassis can handle to 500hp (probably)all i am worried about is IF i upgrade to this turbo, will it put my cars numbers around 400-500hp? cause that would out-class my skill level...... and if so, i will definately wait until i adjust to a more powerful car (owned a camaro that was pushing 350 at the wheels, but it was the fastest thing i owned, so my skill as a driver still needs to grow)

but anyway, holy lecture... any opinions? comments?

Woah, slow down buddy, TMI. First off make sure the swap is done right, replacing all necessary parts before putting the engine in like motor/transmission mounts, clutch, brake, coolant steerings parts, etc. If you're doing cams and turbo you would probably wanna upgrade certain internals too. Unless you're a baller then do whatever you want.

i am making sure all of that goes in, obviously, there is alot more involved than what i mentioned, but i am just trying to get a grasp of where my power will be, so i only listed the parts that i felt relevent to the power/torque

Ok, in my opinion this is what I would do. Before turbo I would get a light flywheel and stage 1 or 2 clutch, and nismo or other motor and transmission mounts. Find out the specs on the cams and if over 256 then upgrade springs and retainers and prolly some other stuff too. Make sure you replace water pump, thermo and any other seals or gaskets. Start off like this and have all your gauges hooked up and see how things are and what you're boosting. Then later get the T28 or whatever with some taka lines, which you can swap out in a day. That's how'd I'd spend my money, but like I said if you're a baller you can do it all at once.

First of all, there is really no need to build the bottom end with the 2871r. I would concentrate more on building the head. My first choice would be peak performance valve springs and stock retainers. Titanium retainers are optional in my opinion. Just get a good tune and your bottom end will be fine. And I would go power fc over e manage if I were you. Its not that much more expensive.

And with the 2871r, I would go with the non drop in version. The one with the 3 inch inlet. It requires not much more custom work and it makes your engine bay so much cleaner. It will also give you just a little more power over the drop in one. Also I would rethink your turbo if you want 400-500. I would look at a 3071r. I have the 2871r and I actually want a turbo that pull harder in the top end. Hopefully after I put cams in, this will change. 2871r with cams and intake manifold will get you pretty close to 400.

im probably going with an xeddy stage 2 clutch, and i have heard that the nismo motor mounts are too hard, so i might look into something else for that, thanks for the imput on the springs and stuff, i will find out what is up with the cams, aparently they are just a drop in replacement, no other modifications necissary. as for my power, 400-500 is not my goal, my goal for now is only around 350-max, i was just wondering where i would stand, and if i could withstand 300-350hp with stock internals..... but it seems to be the reccomendation to rebuild the top end if i sqap my turbo. i am leaning towards swapping it in later...... and as for the e-managa, i wanted a full standalone, but i am tuning-retarted, and the local shop only specialized in greddy.... so i am stuck with e-manage,.... boo

iirc stock internals are good to 450hp..so you should b good on bottom end internals, someone correct me if im wrong. thanks

[Night_Stalker]

oooh please, no body correct him... i want that to be true

lol. some people are making huge numbers o nthe stock bottem end. make sure you do a compression test. for your goals the stock bottem end will be fine. i am planing on 400-450 chp on stock bottem end. check out my build thread looks liek you want ot d oa build alot like i am i nthe middle of.

oh you didnt have injectors o nthat list, upgrading turbo requires new injectors. 550cc at least.
