i might end up rerouting my cold side like this, but in 2.5". more cost effective than going with a new intake manifold.

doesn't look too bad.

That is one of the better setups i have seen. You should also check out the hybrid r33 kit. I have it on my car and it turned out really nice.got it from http://www.240supply.com

I have pics of the install in the Members' Rides Gallery

boostsfed, is that a custom piece or can it be purchased somewhere?

it's a custome pipe. i will fabricate one in the near future. currently, the charge pipe for my fmic is still using the stock elbow w/ stock bov.

are all those welds butt-welded or is there an overlap? maybe a mandrel bent steel pipe is theway to go or cast aluminum?

Looks like alot of man hours invested in that one.

look like they overlap the welds, but what i'm planning is a mandrel bend aluminum tube in similar fashion.

Interesting that a setup as nice and modded as that uses the stock IM..

i'm thinking so as well....i don't know if i will ever put down enough power to put the stock IM out of its efficiency.

i was thinking about going same way with a mandrel bent

but wont that make the pipe hot before getting into the intake ? being on top the valve and all ?

i was thinking go out on the side just like a sidemount and route the cold to cross over the intercooler then in infront of the radiator

the hybrid kit is pretty nice but little pricey ?

as for right now, the stock pipe run accross the head is already heated quite a bit. maybe wraping it helps.

i have tried that initially, it's about 1-1/2 foot extra of piping, too long IMO. i think runing the charge pipe like in the picture above would enjoy both world, while not needing a new IM.

how much should i expect to pay for the piping u think ?

i picked a huge front mount and now its time to custom some pipes

called turbotrix in NJ they said about $550 - $750 ( which i think is a rip off )

he tells me cuz the pipes are shiny

remember guys, velocity is just as important as volume. a 3" charge pipe is HUGE. i dont think most of the people here run turbos big enough to warrant that much airflow.

i agree...i would say 2.5" is the idea size

just a bit of trivia: I think the engine in the photo is an RB20DET-R, a special racing version of the early model RB20 that came out in the GTS-R. They came standard with that exhaust manifold and a T3/4. And it says RB20DET-R on the little plaque where the others have ECCS or NICS but I can't quite see that in the photo.

i don't know the origin of the manifold, but the car is the GTS-R.

more pics of the setup;

if routing this method, what issue may involve if i bypass the boosts selenoid?

Here's an old issue on this topic... it's a 120 deg bend and is suppose to be optimal for flow in stock manifold's setup... going by some of the Aussie tuners.

http://www.nicoclub.com/zerothread?id=63443

Has anyone tried to close their hood with a 2.5-3" pipe sitting on the front of the motor? I never got around to doing it on mine once the motor was in and running.

Here's another post about it which has a good link in it on the issue as well(in which I was rude to Fito for hijacking... sorry again bud)...

yeah, i've roam all over the aussi forums. that's my plan for the next mod. picture can say a thousand word

right now, the top "L" charge pipe is heat soaked after awhile, i think it's mainly the way it sits on top of the head, plus my downpipe isn't helping either.

my plan is also cutting the hood for some ventilation in the engine bay.

Might not be a bad idea to have any charge pipe you use cerami-coated to keep it cool (or wrap it)... even the 120 deg version. I'm still want to know if the hood will close with that 120 deg setup...

I might cerami-coat my current setup as I'm not a huge fan of the "bling" factor of my charge pipe... and I'm sure the hot air from the radiator doesn't help keep charge temps cold.

i'll be making the pipe soon, i'll let you know if it clears the hood or not.about the heat issue, i plan to ceramic coat it + wrap it to minimize the heat from the head.
