Sand is a pain in the ass you will never get a nice bend will still flatten out a little and you will struggle to get more then 35 degrees with out pipe damage. Buy round donuts can get any angle you want then or a proper bender one that rolles the pipe not crushes and hope it turns out for the best im not trying to be a rude basted I'm just telling you my experiences

Hey Blake what I the best way to cut them donuts up ?

Pedestal jig saw or something like that ?

Bought a TIG, a tube folder (wanna be bender) going to build a roll cage.

Have a go, I love it........

44mm tube is cheap at bunnings, can use galvanized fencing, it's thinner and lighter than the stuff in the steel isle.

If you want to have a go I have a proper mandrel bender your welcome to try.

hi risking i was in fact going to go for cdw 44mm tube

i have had a lift tig for a while now

and my mate has always bugged me to make a cage for him its a ae86 with no more that 140kw that he uses for drifting ( no cams )

i am aware that the ( tube folder i have ) is TERRIBLE. but there was only 1 way to find out there terrible and that was to give it a go.

I'm now going to go with get brown Davis to make me the main hoop and i will build from there

Hmm and for the pun about me going to do it with gal..

I don't think anyone on this part of the forum would be that stupid

that is a stupid insult

and thanks heaps for the advise BSA you are right on the dollar

anything over 35o is somewhat unachievable 2011-11-15190505.jpg

I usually use I angle grinder with a alloy cutting disk or just a 1 mm cutting disk then tig a bead on the end. It can be hard to cut straight but just takes practice can always grind it straight. A chain cuter would be the best I think only done it a few times but makes life so easy. I'll be doing my cooler piping properly soon using stainless because it's more available to me not worried about weight

yeah i got a drop saw for doing the cuts. works out a treat

making a jig up atm so i can doe more drift pipes for mates

i really want to do more inter cooler piping though

iv already done everything for my cars and for a couple of mates

played with alloy abit more last night

i need to get better with it. 2nd time playing with alloy and i made this..... its pretty lol :P

Can't use a drop saw to cut donuts works on everything else but. A side note make sure you have a dedicated disk to stainless and alloy don't cut mild steel then cut alloy or stainless with the same disk it will contaminate the metal then rust or be a bitch to weld

I usually have them all seprate on diff hooks saves a world of trouble. I have a perfect example I was making a forward facing plenum for my 20 and I cut it out using a 1 mm disk acidently put one I used for steel then when I went to weld it had all sorts of trouble with inclusions had to back grind everything wasn't happy tho so I tossed it. Now all disks are kept separate and tidy. Also you may find it easier to weld alloy of you wipe it down with thinners, cleans the surface much better

More Practice :)

All the mates are Rapped Sept for the one that now has a defect

so it turns out i have one set of pipes spare :P

Tomorrow going to make in intake for my turbo builder Then onto making piping for the 180sx :)

do they have baffles inside or are they just straight pipe?

they look good, only thing I can thing of, purely from a performance perspective is to not have such a sharp angle where it splits into 2 pipes, but really not going to affect anything unless you have heap and heaps of power

Yeah mate Sure could do them in 3 1/2 or 4 inch in i reckon if you got a 4 inch zorst you should go for 2x 3.5 inch outlet 4 inch inlet

heres the pic of the inside aswell

    • Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi 
    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
