Hey, i was looking around and figured that i wana build my own turbo with a little help from the org and Alex. Well make the long story short i wana get an idea of the pipes diameter, length, and degrees of bend etc.... I have a blue print based on this pic you see. Welding will be done. I basically need a write on what i stated. Pics and general outline would be appriciated. BTW Its a 5 speed 1995 Maxima. thanks again.

 

buy some bends and pipes and flanges oil lines fittings random nuts and bolts some fuel nessesities and call it a day. personally i wish i could just make an up-pipe downpipe oil lines and charge piping and be done why does it have to be more complicated?

 

I am, planning to use this same setup you have a picture of there, but i will modify it a little... You see that red pipe that carries exhaust gasses from headers? it seems kind of long and will generate more turbo lag. what i want to do is reverse the rear heared pipe so that both right and left bank of cylinders would join into one pipe directly underneath the engine and from there go back up into the engine compartment. I will go try to modify that pic to show what i want to do...

 

you cant do that...its shaped like that for a reason, GROUND CLEARANCE. think about it and if you have to, look under your engine to see that it would be hitting every drivway good thinking though

 

there... see, the joint will be pointing towards the driver's wheel and the pipe will go straight up to where the battery usually is...

 

thats where the tranny is

 

This the thing, engine moves constantly that why we have flex section. The drawing you have need a flex section welded on or it will snap and damage pipes. Good brainstorming.

This Pipe would work but, i am trying to minimize turbo lag. Getting evey HP as posible.



Any ideas would be helpful.


BTW when we get measurements would anyone be intrested purchasing custom made pipes.

 

BTW, If anyone is intrested and would like to help on the project please contact me. Only if you serious. I can get my hands on pipes, i know machine shops, and also i can get welding equipment. I live in PA. NJ, NY,MD, PA, CT people are welcome to take a shot at this. Trying to get many people on this project, meaning cheaper for each person.

 

if there was just a pipe kit available, i would love to get my hands on it, especially the segment that goes from a turbo to the cat. if someone would be able to fabricate each pipe separately, it would be awesome....

 

We are in the process of fabricating complete setup pipes. Will keep you informed.

 

yeah you are going to have a problem getting around the tranny with the pipe feeding in that direction.

 

anybody know who did that autocad-type picture?

 

Got it off the this site. I shows you who has that setup.

Click Here...

 

I am still working on the design, but eventually I WILL make it the way i want. My current design will prolly have to be modified, but no kit was made from the first trial...

 

id love to have just a piping kit, that way each persons kit is more of a custom kit. i know its early but any idea on pricing. is this strictly for 5spd

 

We are currently working on a 5 speed. I know later down the road we might have an auto version.

 

Im Alex and ill be working with tman on this project, as far as pricing is concern we are not sure untill we get the first prototype done .

on_alert made the original cad. he did it for a school engineering project.

 

What is so wrong with the tried and true reverse Y?

 

look at the length of that thing... there's a lotta air that needs to be compressed before the car starts boosting. that is why the perfect place for a turbo is on a header...

 

I said REVERSE Y. Not the one in the CAD.

 

well the clearence issue this is removing one fan but we are concidering making both designs

 

Something like this i suppose?

 

You just bet me to that pic, I know most people includeing me are routing the pipe in front of the engine

 

Yes. The fan in question can be removed and a push fan can be placed on the other side.

 

I think there is a way to keep the factory fans

 

that piture is VERY close to what i want. Who made it for you?

 

Got it off the website. We are trying to get a best setup to work, without the hassle of relocating. Basically Plug and play.

 

just one noob question.... That wastegate right there... is it manually adjustable? Do i need a boost controller to run with it?

 

I now have the piping that was made from that CAD pic. On_Alert desinged and fabricated it. Had it installed for a short time. Sold it to Nealoc187 but never installed it. Sold it to me and it will be on my car shortly.

Here is a better pic of the pipes I recently took.

I think it is time to get thoughs pipes painted with Jet Hot or something.

 

check my car domain site for my pipes. i kept my fans and i dont have that u bend in mine either

 

Don't worry, I am droping them off to get ceramic coated in a statin silver color tomorrow morning.

 

And with a properly sized turbo, lag is still minimal. With the Uturn pipe like that, I'm still seeing full boost by ~3200 on a pretty big turbo. The other setup we built used a smaller turbo and he saw full boost at ~2800. In theory, yes of course a shorter pipe is better, but in reality it's not as big of a difference as you think.

After I get my current setup tuned at 12psi, I'll probably rework all the pipes to the reverse Y setup but with the turbo on the passenger side like Hal. It would require new fans and a custom radiator, but I think that's a worthwhile sacrifice to essentially eliminate about 6 ft. of feed and intercooler piping.

 

I believe on_alert isn't around any more... anybody know what program was used to make the drawing? Was it just AutoCAD?

 

Does anyone have pictures of Hal's setup?

 

What psi is "full boost" and for which turbos again?

 

It was autocad I believe. He posts here every once in a while.

 

let us know when u guys start selling them...if u make a setup for the auto. Count me in.

 

Pick a thread.... this one, the one in the fourth gen forum, or a new thread...

There is going to be to much cross posting. Pick what you wana do and let me know in 24 hrs.
