cool... i think i'll wait to see your slip before i decide what a/r i want to get lol

The true disco potato is the .82 housing....however the .64 has got to rock out as well.

I'd say either will work....I'd just favor the .82 on the 28RS, and the .64 on the 2871r....

wait you mean .86 right? but you can get an .82 from atp with a t3 housing



walbro 255lph fuel pump, pwr intercooler, and greddy type-rs bov are all on the way

hahaha yep! My fault at that, was sleeping at the keyboard


PWR makes really nice ish too

yea i got it used for REALLY cheap! the thing about it is though, one of the endtanks has a 2.5" opening and the other has a 2.75". weird.. does it matter which way i put it? and while we're on that topic, what size IC piping should I be looking for. im thinking either 2.25" or 2.5" but am not sure if there will be a difference between the two. also, i've seen where some people have used different pipe sizes in different sections (cold side, hot side, and whatever you call the part that goes filter->MAF->turbo), whats that all about? thanks

[Dark]

i believe you want to put the 2.75" on the hot side, and 2.5" on the cold side

i see. does that mean it is preferable to use larger pipes on the hot side? or does it not matter

[vaser3120]

it would be the other way around.

2.75 from the intake to the IC, then 2.5 from the IC to the turbo

??? im really new to turbo, but doesnt the turbo go in between the intake and the IC?

or do you mean 2.75 from the turbo to the intake manifold? (throttle body)

sorry im confused

[Dark]

he means exactly what i said...
you want 2.75" piping from the turbo to the ic then 2.5" piping from the turbo to the throttle body

i believe the reason for the reduction in size is to limit pressure loss across the IC.. i could be mistaken but that seems like the most logical reason as the same amount of air being forced thru a smaller piping size will cause pressure to rise, cancelling out any loss on the IC... correct me if im wrong.

if he means exactly what you said, then why would he say "it would be the other way around"? and dont you mean 2.5" piping from the IC to the throttle body? what piping runs from the turbo to the throttle body?

now that makes sense. thanks

Anyone else care to comment on this. I still think the way i said it is correct.

Usually the outlet on a turbo is small 2.0-2.5, you dont want to use piping bigger then the outlet size, cause then your messing with the pressure. The TB inlet is not 2.5 its closer to 2.75. So when you look at the sizes from the turbo to the TB, from the turbo you take the size of the outlet to the IC, then take the TB size and match that to the IC.

Also, 2.75 IC plumbing is not needed, your losing pressure by doing it, and its just a waste of money. Cant recall anyone with a KA except maybe a small very small select few that are using 2.75, and they are using bigger turbos and Intake manis that would require larger piping.

Make sense.

yes it does thanks. i knew where things are supposed to go, i just got thrown off when you said intake i thought you meant filter (im still thinking n/a with cold air intake) so i got confused.

so basically what i gather from everything you just explained, is to use piping on the hotside that is the same size as the turbo outlet, whatever that ends up being. and then either 2.25" or 2.5" from the IC to the throttle body will be just fine? (2.25" should provide better response right?)

greddy type-rs bov - $130 from SnapS13 on zilvia

the previous owner painted it black but i cant seem to get the paint off so i guess its staying that way



and with the recirculation fitting attached

[zadeluca]

bunch of little shit from msd for the injectors
injector plugs (part# 2400)
limiter clips (part# 2110) - and i found out from JWT that yes these do come with the JWT fuel rail but i didnt get them since i got it used
o-rings (part# 2100)

total: $38 from autozone



PWR intercooler - $125 from huyqvu on sr20forum





the core is 22x8x3 which according to PWR retails for $495 and can flow 720 cfm. they dont say me how much HP it supports but using cfm=1.5*hp tells me its good for 480 hp. or in other words, more than enough for me lol

as you can see its in really good shape. its got some weird custom brackets from the previous owner that i'll probably end up removing. end tanks are 2.5" and 2.75".any more thoughts on the IC discussion from before? i.e. which should be the inlet and which should be the outlet? and what size IC piping should i use in the different sections?

right now im trying to do more research on IC piping sizes... the compressor inlet on the gt28rs is 3" and the compressor outlet is 2". so all i know for sure is that im gonna use 3" pipe from the filter to the compressor inlet since it is 3" and the outlet on the cobra maf is 3" as well. oh and i plan on getting an amsoil filter (part# EaAU3560. its round/tapered with a 6" base diameter and 5" top diameter, and its 6" high with a 3.5" inlet for the cobra maf. yes, i realize i dont need this huge ass filter but it will look cool lol)
