Nice pics. I'm thinking we should just meet up sometime, take it off and I can measure everything. Still don't know where to get little tubes to weld. Copper/brass/iron is easy as they are plumbing. But plain steel is a little harder

What are you doing Thurs? I can come up to you.

Cardan-dude. You do know you will have to do some cutting into your fenderwell. You will probably have to measure and figure out where to cut. Unless Sarin wants to take off the intake again and shoot some pics of where to cut.

 

yes, I am aware that I have to cut into my fenderwell....I was hoping I could just expand the factory opening....I am sure sarin can give me a good idea of where to cut....and I can also eyeball-it once I get the pipe put on the tb.

 

From the throttle
Is that pipe 2.25"?

 

Jeff, I might be working at Dave's garage. Got to replace Ian's clutch this weekend, so we're prepping that evening....though with how things are with Dave, we'll probably have to meet at my house beforehand......he's been a little wierd about the garage lately, so I don't want to further aggrevate him. So if you are free Thursday after 2pm, that should work out fine. Also the fitting Jose used were copper. Some of the paint came up when I was pulling one of the hoses off to get to the small hose to put a clamp on it.

Carson, I will definately keep tabs with you on how things are going. Also if we do pull the CAI again, I will try to get pics of the cuts in the fenderwell. Though IIRC, mine was a little on the small side, but still works fine.

djmaxx88 (I dunno what your name is sorry...), My intake is full 3" piping. IIRC, the outer diameter of the TB is about 2.75" however.

Cool thanx mann!

 

I work until 5 so meeting before is out. Well I don't want to make things worse, so we will have to meet some other time. I guess the other guy brazed the tubes. Plenty strong but I don't have/know how to. I need steel.

 

Yeah, we'll figure something out.

S

 

In addition to the CAI, you should pick up one of the hogged out intakes from me, they are rated at 40 - 50 cfm increase in flow and ready for the 240sx 90 mm tb. See 'turbo a 2nd gen' for pics.

 

How much you asking for the intake?

S

 

Question. Does the CAI have to be 3"? I believe your tb/maf etc.. is more like 2.5"? 2.5" = about 63.5 mm

 

I am not sure of the answer to your question....but most of the companies that actually do R&D on there intakes (injen&AEM) use bigger pipe(3"ish), I am assuming they do this because they generate the best results with this diamter pipe...dunno for sure.....
on another note have you made any progress on the CAI?

 

I've been unable to meet with Sarin for to get some measurements on the midpipe. That is really the only thing holding me up. I don't know what size tubing I need for the midpipe. So once I know, I'll have to source them. The one that was made for him, featured brazed copper tubing. Which is fine. But I don't know how to braze nor do I have the equipment to do that. I only have a mig welder.

 

If you could tell me the size and how many vacuum fittings for the midpipe you are going to need, I can look around town and try to find them here

 

Honestly, if I knew that, I could be digging around already. The best thing is to get Sarin's midpipe and go from there. Sarin if you are available this Sat, let me know.

 

Jeff
I made the midpipe for Sarin. Two of the fittings should be 5/8, one should be 3/8, and the smaller I thought was 1/4 but according to what I heard from Sarin it is too small. Its weird cause I used the 1/4 fitting on my midpipe and it worked out. Ask Sarin for the correct size of his fitting(smaller one). by the way I used copper pipe and brazed them. Hope that helped

Jose

 

Thanks. So if the OD is of those sizes, I'm okay?

 

Jeff, I'm gonna be near Lakeridge/Renton/South Seattle this Saturday, but I dunno if I will have my car with me yet.

S

 

Actually if you don't have your car, anyway of taking the mid pipe off? That's all I really need? Let me know

 

I might be able to do that. But I'll let you know how it goes.

S

 

I'll pm you my cell number. I'll have it on all day Sat.

 

I looked at the pics of your CAI, what did you do with all of the vacuum lines that were running off of that one part that connects to the stock intake? I remember I didnt have a few of them hooked up and my car was getting very very slow response when I would hit the gas pedal.

Nice pics though.

 

Carson,

Update for you. Jeff and I got together today. He took out my mid-pipe, made measurements, cut the mid-pipe to size, and drilled holes for it.

Here's a pic of Jeff hard at work scratching his head.



S

 

You really need to strip the gold paint of that intake cover and polish it up! But that red wire loom looks kick-a$$!

 

I recognize that mid pipe....looks really good..LOL Nice engine compartment Sarin.... Last week of school and then its back to the drawing board for the redesign

 

lol! I have my stock one sitting somewhere. Need to get it out and polish up.

S

 

thanks for the update....keep me posted on the progress

 

Nice pics! ha!

I worked on the midpipe. I got some little pipes that were similar to the pipe size the other gentlemen used. To the best of my knowledge, they should work. If anything they might be just a tad big. I'll taper the fittings so they will slid on better. The small fitting will be a pain. I already welded the two big pipes. But now I won't have enough room to weld the small one! Oops! I might use a brass threaded fitting and locktite it. Should seal plenty.

Or I might just make another midpipe.

 

How much do you think it would cost to build a midpipe for a 2nd gen?

Like, buying all of the materials, then getting someone to weld it all together.

 

Unless you know someone that welds, their time might cost more than me just making one for you.

 

I think after everything was done, I paid close to a 150 bucks after everything, not including mid-pipe.

S

 

Hey, Sarin, When you guys are done doing all this, could you send me all the dimensions, lengths and sizes for each piece? My only concern with using steel for a CAI is the possibility of rusting on the inside, and then getting into the engine. I'd like to do one with aluminum, I have a MIG setup for al at work. Either that or do an ABS plastic one and glue in brass fittings. I have some glue used to glue body panels on to trucks, the only way to get it to let go is with heat from an oxy/acetylene torch!

 

I used aluminized steel for my piping, and yet to have a problem with rust forming. But I'll see if Jeff is up to making measurements from the kit he is building to send you.

S

 

Jeff92se: how much would you charge for a mid-pipe?

 

Well I think I'll make another one anyway. The tubes aren't perfectly straight as they come out of the tube. So probably not much if you want this "prototype" unit. It's not bad at all. You wouldn't even notice it when it's installed. But I'd like another crack at getting it right. heh.

It's easier for me to make another one vs cutting this one up and rewelding.

So like $25 shipped or something.

 

Hmm, I'll think about it. If I decide not, I can always have one of the kids in the metal shop class at my school make me one (some can weld pretty good)

 

Good news! I got two midpipes done! Both aren't perfect. So it's a toss up to which is better. And to my knowledge, the pipe sizes should fit. The little hose fitting that was too small on Sarin's was replaced by a brass barb style fitting on both of these.

I'll taper the pipe ends to make the hoses slip on easier. If anything, they are just a tad big

For the rest of the 3" pipe. It's all marked. Just has to be cut. One of the pipes will either be too long or okay. I'm not 100% sure on that dimension so best to leave it long vs short. It might work either way as it's the pipe that the filter is attached to(in the fender) This will only take 1/2 hour to cut.

As of right now, they aren't painted.

86wagon. If Spilk188 doesn't want the midpipe, I can probably grab another set of 3" pipe and duplicate the cuts for another complete setup.

Or I can just make another complete unit.

Now I would have liked to have Sarin's car to confirm all the little fitting sizes but again, I've done the best I could do considering I couldn't braze and use copper tubing. The steel fittings are close (very close in the OD measurements.)

 

so is there a full CAI ready for me? minus the filter and MAF adaptor plate?

 

After I cut the 3" pipe, it will be done

 

cool just let me know....and if you could just pm me with how much money you want that would be good too. Thanks for taking this project on

 

Werd, good to hear you've gotten some progress on this Jeff. That was pretty quick!
