Okay guys I am still in the non-boosted stage of my weakling d16y8, but the plan is to be boosted by the end of summer. I am hoping to be able to get a good amount of power and still keep my civic reliable on long drives and have a quick car. Right now I am hoping for 275-300 whp and would like to hit high 12's on street tires. Here are the things I plan on doing, some i have, most I dont. Anyways here is the plan, and I am on a budget, I am going to try to do things myself, and take the extra time to find great deals becuase I am CHEAP. So with this list of stuff I plann on doing, are my goals resonable? Can these parts take more power? Less? What is my weakest link?

-Probally a log mani with external wg (ac compatible) do the ac compatible logs that have an offset flange flow badly?
-probally a used name brand wastegate (sometime the ebay ones look tempting but I dont know if thats worth risking my motor and turbo for
-some sort of used snail, thinking like garrett .48 .60
-ebay special fmic and 2.5 piping
-2.5 downpipe gunna cut it? I have like 2.25 inch exhaust, maybe 2.5, so I am not sure if I will consider doing a cutout or something and possibly do a 2.5 or 3 inch downpipe
- 550 injectors
-uberdata street tuned by a local tuner
-stealthmode oil lines prob (may peice together my own set)
-vitara pistons
-some sort of rods that will fit vitara's
-arp head bolts


Ok so I was thinking that if I get a snail that can push it efficiantly that 300 hp should be doable with and that the engine could probally take it with the arp head studs, and the pistons and rods. What do you guys all think? This is my first time boosting a car, so we'll see. Any help or advice would be greatly appreciated. And yes I have searched and researched any and everything about turbos for like months and months now, just I would be curious to see what you guys say about a setup like this.

I would think on a good tune that everything could handle over 300, I thinkt that the pistons would be my weak point as they may not be safe past 310-325. What do you guys think?

i didnt see what motor this will all go on??
:1 1ST LINE I SEE NOW.

if ur exhaust is crush bent i would try doing a cut out or get some new exhaust. when i hooked up the little exhaust on my turbod b16 u could tell a diff.
and like these guys said try picking up a t3/t4 u can get them fopr about 300 bucks some times used

Minor Threat

If you're adding pistons and rods, you're mostly going to be limited by compressor choice/fuel. You want 300, pick up a used t3/to4e.

StanB

Possible weakest links in my opinion are:

1. You're tuner's ability.
2. How well the D16Y8 head flows. You might be better off using a D16Z6 cylinder head.
3. As Minor Threat stated, the efficiency of your turbo.

imo, that the turbo you've chosen is gona hold you back. get a bigger compressor.

but I agree wih stanb on everything.

if u want ac compatibility, have a local make ur mani. I bought an ac compat. online and there was no way it would clear with a t3/t04e on a y8. So i just scrpaped my ac, but if u have ur heart set on keeping it, id have the mani mocked up in ur engine bay

thanks guys I really am not sure about what size turbo will be best. What do you guys think would be a good choice with a resonable cost? To be honest I had been thinking less power, alot less, and then decided to get some internals and up the boost. And really I am just trying to see the limits of what everything can take by asking you guys. Really I am looking for somewhere around 275whp, its just if it can take 300, then why not. So, think the little d16y8 with arps and some pistons and rods could handle over 300whp? Stock sleeves

what a/c compatible mani did you get? Was this a log? a ram? and ebay special? Unfortunately I am set on keeping a/c, it sucks, but I really can't or won't go without it, so it may be another pita I gota deal with. Any one know of who makes an ac compatible mani that will fit a bigger turbo?

check that out, if u scroll down the d series is there.
try searching around under some of there names and u will probably come up with thier setup.

there is no way your gonna post a 12 second time on street tires, so you might as well plan on investing in some slicks or drag radials. Your car is gonna spin like a bitch on street tires
