I.C.C.

Decided to stick with a ramhorn setup instead of jumping on the top mount bandwagon, but I am curious to see how people have done 4" downpipes with the ramhorn style manifolds. I know its been done, but never really taken the time to look at how...

I would prefer to see EG Civics just about anything will work for ideas...

I.C.C.

anyone?

bump for one more try!!!!

I tried it when making my 3" DP in my DC, we cut my pasenger headlight a little and moved the radiator all the way as far as it would go to the passenger side, it would physically fit but the issue was getting 2 of the lower bolts into the exhaust housing, we had to make such a sharp angle off the turbo to avoid the radiator and the slave cylinder there just was no way of geting the bolts into the housing, so we scrapped it and went 3". One easy way to do it would be just run 3" off the turbo and down past the slave cylinder and then increase it to 4", which is what I plan to do this winter if I keep my manifold/turbo setup.

well luckily my turbo is v banded on the outlet which will allow a tighter bend as i dont need the room to get bolts in etc... Thanks for your input though

Yes that helps, but doesnt the V-Band push the flange out further away from the turbo? All the Garrett ones I have seen stick out a good inch or so from the side of the housing, which only makes space issues worse.

On the T3 housings some stick out... This pic will show you how mine is...

I have a ef hb with a gt 35 and a 4" downpipe.. I made everything custom myself.. The manifold is an early full-race one.. I modified a eg PWR radiator and welded the lower mounting points for the radiator in front of the traction bar.

I only have a pic when it is on the engine dyno and one of the downpipe it self.
The car is about to get rady for paint so it is striped clean right now.

Thanks for the input man... Looks good

Just need to gather ideas of how to cram mine in somehow haha

96 GSR-T

Is that just me or was that car on an engine dyno? I bet it would be easy to fit a 4" DP in there without a tranny in the car, I would like to see that DP clear the slave cylinder.

The sweed

Yes it is on an engine dyno. I have a tilton twin clutch and the hydralic throu out bearing. It has been test drived only before paint.

Thats december in sweden and it gets dark by 1 a clock.. DArk videos..

I cant pull up my pics but I've done it with ramhorn and its not pita. you need real tight radius bend.

in for pics and a material list, I would really like to do this but it appeared too difficult to me before.

If you happen to come across any pics I would love to see them... My biggest fear was clearing the slave cyl. and trying to not have the DP resting right on the radiator... Once the motor is fully assembled and back in the car so I can mock everything up Im sure I will get a better idea of how to do it, but I was already fairly certain I would need a pretty tight bend...

Does anyone make 4" donuts or am I stuck pie-cutting my *** off???

http://www.atpturbo.com has 4" stainless 90* bends that have a 4" radius. this is what i used for my downpipe. reasonably priced also.

I.C.C.

the biggest problem seems to be the 3" to 4" transition taking up all the damn space lol

redboost10

actually the one that i used was also from atpturbo, its only about 2-2.5" long, cant remember off the top of my head, but i do remember you can take about .5" off of it also and still be at 4" od

alot of tight pie cuts will do the trick

In for some pics...I want to do this in my DA...

I used 92-96 Prelude slave cylinder. It worked great.
