intercooler piping for s14 sr20 in s13 chasis

[gippy87]

alright well im sort of lost here, ive only had redtops in the past. I see pipes that say s14 sr20 hot pipe but im lost they dont say if the hot pipe is for use in an s14 chasis or if the hot pipe is to be used with s14 sr20 in s13 chasis. Im looking to buy one of those cheap greddy fmic kits and just wondering if there were any additional pipes i would need to buy to make the kit work with an s14 sr in my s13.

plumbing is engine specific not chassis specific on intercooler piping

[gippy87]

So are you saying i will not be able to use my s13 sr hot pipe with an s14 sr?

[Ninjabread]

You could but You'll have to mod it because the outlet comes out at a 45* angle instead of 90*.

So you can cut it, and run a 45* coupler, or mod it so that it has a 45* angle.

Orrrr, you can get the greddy outlet, that repositions it to 90*

what about when buying the greddy fmic kit i see they sell one for s14 sr20 but it says for use in an s14 240sx with s14 sr20 only. I want to make sure i get the right cold pipe cause im pretty sure the throttle body also comes out at a different angle then the redtop.

Also if i were to buy this hot pipe http://www.courtesyparts.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=CP&Product_Code=320-1103
would that eliminate the need to buy the greddy outlet? also keep in mind its going into s13 240sx

[gippy87]

Im sure somone on here has a s14 sr in there s13. What are you guys using for piping i really dont want to order the wrong stuff. These websites are confusing the crap out of me courtesy parts says s14 sr20det hot pipe but the part is listed under 95-98 240sx yet someone said that when talking about piping they are talking about the engine not the car

Alright still no help here. "This is designed to work with the S13 chassis and S13 SR20DET Motor. Can be used with S14 Motor but Cold pipe piping will need to be modified." same message for greddy s14 kit only it says made for s14 with s14 sr. all i want to know is what will be the best greddy kit to buy that will need the least modification to work with my engine.

[tt99ol]

yeah the coldpipe is completely different for s14 sr as compared to s13 sr, the stock bov is on the coldpipe on s14 and on the intercooler on s13, also the throttlebody is in different locations on each engine.
The chassis' are so close in shape that you can get an s14 ic kit and all you gotta do is make new mounting brackets which is like $5 at home depot

I ran into a similar problem. I have a ca18det in my s13 and the throttle body sits up high like an s14 SR. I talked to the guys at 240sxmotoring.com and they told me my best bet would be to get an s13 SR kit and get the cold pipe modified. The s14 SR hot pipes are routed differently to fit an s14 chassis. There is a hole in the s14 chassis that the s14 hot pipe was designed to be routed through which is why it won't work in an s13 chassis.

I'd say your best bet would be to get the s13 SR kit and modify the cold pipe. I bought the greddy ls-spec s13 SR kit. Just waiting for the shop to call me back about getting the cold pipe modded... OR.... If you want to cheap out you could probably get the godspeed ca18det kit.

Here's a pic of how the s14 sr hot side is routed. Notice how the hot pipe goes down on the inside of the frame rail on an S14. It then goes through the frame rail and does a 180 back to the intercooler. It is routed much differently than an s13 hot pipe.

thanks for the help. so i guess i will go with the s13 greddy kit and mod the cold pipe.

[mestizo]

I just did an S14 SR into my S13, neither of the piping setups will fit with out modification, to be honest there is no real good solution to this except for getting both s14 and s13 piping and making them both fit. It's not as simple as getting one hot or cold pipe to work since the s14 hot side is routed differently to the smic than the s13 hot side. Same goes for the cold side since the intake manifolds are different, also the BOV's are on different sides of the car.

On my car I bought the greddy m spec kit before i decided to get the S14 SR, so from the turbo to the throttle body its s14 stock hot pipe cut to fit an after market s14 hot pipe, which goes to the s13 greddy lower hot pipe and 3/4 pipe cap where the S13 greddy BOV flange is at. Then from the cold side of the intercooler to the greddy s13 elbow then to an after market s14 cold pipe which was cut to make the angels of the greddy hole position work.

I know it's not the prettiest, but it works for now until i buy all new piping and have it all redone.

I think you are confused about the piping. The hotpipe goes directly from the Turbo to the Intercooler. It is referred to as a hotpipe because the air is still "hot"- because it has not been cooled through an intercooler yet.

The coldpipe routes from the Intercooler to the Throttle Body. It is a cold pipe because the air is "cooled"- it has now passed through the core of the Intercooler.

I hope this helps with any confusion. It is probably best that everyone on this post understands what pipes are what.

The hot pipe that people refer to is not the entire "hot side" of the intercooler.

The hot pipes are not included in intercooler kits. Notice how the pipe that connects to the intercooler on the driver side goes up into the engine bay and has a tapered (2"?) end? That end is tapered to connect to the "hot pipe."

I'm not sure that you really know what was being discussed since you dont seem to realize the difference between s13 and s14 hot pipes.

I'm also not sure that you realized this thread is 4 months old.

[QuickSpoolSR]

lol, he gets on a 4 month old thread and explains what a hotpipe is.. wtf haha

And your a fucking idiot for bumping a 9 month old thread...:bigok:

[gippy87]

haha i was just on google searching for s14 cold pipe and my thread popped up first so i felt like bumping but anyways since the time of this thread ive done a built up 400whp sr20 sold it bought a gsxr sold that and bought a 240 with s14 sr in it. Now im trying to find a cold pipe for it cause the previous owner hacked the shit out of this one.

[TurboStrong]

im using s14 piping on my car and i have a s13 with a notch top!
