ic to intake? there is no such thing. there should be one pipe going from the turbo outlet hose to the IC. its a 90* bend and a 45* bend (some use a 35). and you wont need a t pipe if your keeping the turbo outlet hose since it already has the dv connection in it. if you remove the turbo outlet hose and run the piping striaght to the turbo, then you'll need a t pipe or just a connection welded to the piping somewhere. then there's the the other side of the IC. it goes from the IC to either the tb hose or straight to the tb. you need 2 90* bends and if you don't use the tb hose you will need a few ft of staight pipe to reach the tb. you dont have a MAP so you don't have to worry bout that. and 2" will be fine, but if you go BT in the future running a hotside equivalent to the size of the outlet of the turbo and a 2.5" cold side would be ideal.

 

ic to intake? ---- I think he means ic to intake manifold.

 

Just go 2.25" all around. It wont harm spool or psi. Plus it will be good forup to agt2871r if you ever plan on upgrading.

 

yeah i meant the intake mani. my bad. and i was planning on putting new piping all the way to the turbo, since thats what my kit has anyway. and i wanna run it all the way to the t.b. also. i still got a few questions though, will running a 2.25" pipe right off the turbo somehow reduce the pressure? or is the size of the pipe once the air is right out of the turbo make no difference.

also i do planning on putting a BIG turbo in there once i save the money, and do a lot more research on it, probably bigger then a 28, so would the piping still be good? or do turbos bigger then 28's need more. i know with a BT im gunna need to upgrade the core anyway, so a whole kit would probably be in order. anyway im gettin way ahead of myself. im just debating if i should stick with my setup now,and make it as good as possible for temp use, or if i should just leave it poorly tuned and save all my money for the BT.

*and by poorly tuned i mean the whoping 8Lb 'chip', the straight pipes with a cat, and the 1.5 IC piping.

 

rule of thumb. Turbo out size to the ic then .25" bigger to tb. There are honda guys making 500whp on 2.25 piping.

 

That would be a Honda. Big difference between lawnmower engines and car engines. [8D]


Edit: You know I'm joking! As cincy told me, 2.25" hotside to 2.5" is sufficient for BAT/DD applications. Hot air compresses better, so you want that slightly smaller so you don't lose boost pressure.


Edit 2: Kraylon, I got the following for $189 shipped:

They custom-assembled the kit. They're very, very nice people, and respond promptly. BTW, for reference, I'm planning to do 300whp, and that application is sufficient. Perhaps a taller core, 8-9", will do better, but you don't really want it thicker or longer.

 

Is there a reason why people don't get local muffler shops to mandrel bend pipes for IC kits?

 

cbehr, I don't see why not. You can also order the piping and have them weld it so the flow is better.

The only reason I can think of, is perhaps the grade of aluminum may be different?

 

thats what i did for the hotside pipe. i had the coldside from greddy.

pretty sure you have a 2" outlet, unless its different than a k04. i dont know what a 28rs has tho. so if your not using the turbo outlet hose or the tb hose using 2" hotside and 2.5" coldside will make thing easiest, since the tb is 2.5", and work very well. the smaller diam on the hotside keeps velocity up and the coldside is bigger to move more air. you just need a 2"-2.5" reducer on the coldside tank of the ic, a 2.5" connector for the tb, and two 2" connectors on the hotside. get everything else welded

 

yeah i know someone that is able to weld alum. so im just waiting for the pennies to add up for the new pipes and some alum. feed for his welder, and im probably just gunna have 2 solid pipes, with clamps on everything, and i think im gunna go 2.25" hot side, and 2.5" cold side. and hopefully buy the spring ill be getting a new core for it also.
