Piping, FMIC, BOV

[Neejay]

I tried searching, but couldnt come up with anything. Would any piping have to be custom for a fmic (hot or cold pipe)? I dont really understand how piping works for fmic. I see intercooler piping kits, but they're for sr20det's. Are there any kits for ca18det's? Or would sr20 pipes work for fmic's?

And does the old saying of "You get what you pay for" apply to fmic as well? For the bumper opening on a stock ka24e (or ka24de if I choose that bumper), the johnnyracecar.com intercoolers seem to be functional enough.

And how does hotpiping work as far as BOV flanges, any premade? I know enjuku has them, but like I said, they're for sr20dets. I plan on using a greddy type-s...

You can use an SR front mount kit, you just need to play with the cold pipe to fit... I hear you can use an s14/s15 kit and it bolts right up, but the s13 works too (you just cut the hot pipe and rotate it using a coupling)...

the hot pipe (from Enjku for example) is the same for SR and CA's... that will bolt right up:)

you do get what you pay for in almost all cases with car stuff, intercoolers are no exception. but IMO the gains you get from a good intercooler setup can almost be accomplished using other means such as copying a good setup (Say a greddy kit) using custom pipes and a nice intercooler core... I made a FMIC myself for around $450 and it cooled excellent. the cold pipe was always nice and cool to the touch, even on a hot florida summer day... I'm still sporting the t25 (from an SR) and all that piping was just a bit too much for me, so I just picked up an ARC sidemount for around $250, and I hope it will work well too! Just make sure to get something that cools well (IE not the stock sidemount);)

So I can use a s14 fmic kit, and it will bolt up perfectly without modding anything. Im a little confused about that last part though "you just the hot pipe and rotate it using a coupling" = you just have to cut the hot pipe and rotate it using a coupling? So if thats true, I can use a s13 kit and all I would have to do is cut the hotpipe and rotate it?

I was thinking of just using the "GReddy/Trust Japan Intercooler Kit for S13 SR20DET" and the "Enjuku Hotpipe + Greddy Type-S BOV (s13 sr20det)".

Spend you rmoney on a good core and sturdy, durable couplers. Bigger is not always better.

Any recommendations? Im not going for an all out track car. I dont need the best intercooler.

Precision cores seem to have a loyal following.

mistyped it :pface you cut the cold pipe... for the SR it angles down, but the CA goes straight in like the s14/s15 kits... the s14 kits won't mount properly though, so you'll need to make a bracket to hold the intercooler (EASY) or cut the S13 cold pipe:)

Kinda on topic: What size piping does everyone run 2.25, 2.50,or 3 inches... because the inlets on my intercooler are 3 inches so i figured it would be best to run 3inches...? Instead of goin big inlet to smaller piping, lets say 2.50... am I correct in thinking this? Thanks

[NeedCAforS13]

smaller piping will work better for smaller turbos... it will be less of a pressure drop. The smaller the tube, the faster the velocity, but there is going to be less flow... to give you an example, I used 2 inch for my hot pipe (stock dimensions) and 2.5 inch for my cold pipe (throttle body dimension). My intercooler inlet/outlet was 2.5 inches and I used an adapter that went from 2 to 2.5 on the inlet of the intercooler...

for your application, seeing as you have a 3 inch inlet/outlet, I would run a 2.25 or 2.5 inch hot pipe, and a 3 inch cold pipe... but I could be wrong:)

Sean

kind of depends on what turbocharger you are using and what kind of boost levels you are aiming for. For a low flow turbo at moderate boost levels you will most likely see a LOT of pressure drop from 3" piping. Ive always gone by the theory that 2.5 is just right for anything short of a race motor.

Sean

Ahh, so you're certain the s14/s15 kits work, but only thing needs to be done is to make a bracket for the IC? Or that if I use the s13 sr20 kit, I'd just need to cut/modify the cold pipe?

I emailed Ray at enjuku and this was his reply:"The S13 SR20DET Intercooler Kit will not work on the CA18DET cause the Intake manifold is in a different position and will not line up properly. We can order a CA18 Greddy IC from Greddy JP and will take up to 6-8 weeks. I personally had the S14 IC kit on my S14 chassis CA18DET, and it the cold pipe was not long enough and had to be modified. It was far from just a little twisting. "

The Greddy/Trust JP s13 ca18det kit is about $920 retail.

Ok so I'll look into getting a 2.5 hot pipe and a 3inch colde pipe, and Street Sleeper yeah your porbably right that would be too much of a pressure drop. I think I'll be running 12-15 psi (prolly just run 14) and its on a greddy td05-14b turbo...now if I can only figure out where to put the bov on the hotside or the coldside and vent or to recirc it:thinker ...j/k:pface

[NeedCAforS13]

run it on the cold pipe right before the throttle body... I am going to re-circ my ARC, but my HKS was venting...

hold on I'll post pics of an S13 SR20 intercooler kit installed on a CA18:)

CA18 with an S13 SR20 Greddy VSPL kit and an Enjuku hot pipe also for an SR:)

That purty... how much was the hot pipe?

1.) What kind of battery is that?2.) So the CP was cut enough to rotate the bend upward?3.) Where's the BOV? And wouldnt the BOV on the HP be better for compressor surge? 4.) So the enjuku HP fit without modding?

Ray said he could do 20% off greddy retail, which would bring the s13 ca18det kit to about $736 (minus shipping Im assuming). Sorry for all the questions, but Im the type of person that likes to have EVERYTHING planned before I make moves and spend money. The sr20det kit is $699...so Im thinking I might as well just get the exact kit made for the ca18 in the s13 chassis for a littler more. No?

[Rookie_ca18]

Anyone know of any sites that sell CA or Sr specific intercooler piping kits, just the piping not the intercooler. I'm trying to get on Enjuku site but it keeps timing out. I know the sell a the hot pipe that Sean has but is that all they sell?

[fanta]

Rookie_ca18:

2.25" hot pipe with a 2.25"-3" coupler and a 2.5" cold pipe will be more than enough.What throttle body will you be using?

[NeedCAforS13]

I would get the CA kit if its only a bit more $... and yes the enjuku hotpipe is the same as the greddy hotpipe, is the same as the phase2 hotpipe... they all copied each other:)

not my car in the pictures either... it belongs to USDM_OneVia or whatever Joe's name is;)

Sean

[Rookie_ca18]

for now stock CA...and I was think 2.5 on the cold and 2 for the hot just have to get some reducers.Thanks man I feel a bit more certain about it now. Do you know any sites that sell sr or ca specific piping kits just the piping? I found one site but wanna compare some prices. http://www.overboost.com/obs/p...iping

[Rookie_ca18]

there is also a 50mm kit for $100 something.

[float_6969]

I got mine off eBay. Mines 2.5 on the hot side and 3 on the cold side. I got an S15 kit and it bolted right up. I did have to plug one line though, and there was a larger line that I cut off and had my BOV flange welded onto.

[fanta]

Whatever you go with, just try to streamline flow - minimize abrupt openings and the like.

Wow, so you got a s15 kit, and piping and intercooler wise, you didnt need to modify anything? What kind of intercooler kit was it?

Alright thanks for all the good input everyone :ylsuper

[fanta]

If you're up for a good read, try out Maximum Boost by Corky Bell. It offers a lot of good information about turbocharging and setting up a system. Great for all boostheads

[Rookie_ca18]

Yeah i'll check it out, thanks.
