Need To Borrow A Skyline Cat With 3inch Flanges

Hey,

So I bought a stainless steel 3 inch high flow cat with no flanges.

I work roughly 9-6PM during the week sometimes later so I waited till this Saturday to take out the compliance cat and ring around.

I found a shop in Moorabbin that would do the flanges for $50, so I dropped round, he didn't have 3inch flanges so he offered to take the flanges off the compliance cat and put them on the new cat.

I said ok.

He has somehow managed to add 200 to 300mm onto the length of the new cat and I cannot fit it into my exhaust system, the new cat was the correct length before he added this length. :)

So does anyone have a compliance/standard/aftermarket 3inch cat that I could borrow for a day or two so we can compare the measurements?

I have an engineering friend who offered to do the welding correctly (very bad welding too), BUT I need a cat to compare to so we weld at the correct length and angle.

Happy to put down some kind of deposit of course, just advise me if you can lend it to me for a day or two.

Oh, and I've booked into RacePace Wednesday so I need it soon..... :D

Anyone have a cat I can borrow? Please....?

I will offer some cash for the lend... :D

Oh, if anyone can confirm if R33 GTST/GTR and other models are the same cat that would be great :)

Regards,

Gareth

the stock gtr cat flanges are 2.5" inch, if he welded them on your 3" cat, wouldnt that defeat the purpose of the 3" cat ??

ive sent you a pm btw, i might be able to help.

Compliance cat had 3 inch flanges because I had a 3inch exhaust :D

The compliance cat was ok but now its pretty much destroyed so I can't sell it :)

Don't think it was worth much anyway...

Regards,

Gareth

i hate it when people do work below par to reasonable expectations. common sense would have said to match the length of the old cat to the new one when he was doing the work and nothings uglier than a half assed weld job..lol.

Yeah, ripped off pretty bad.

Justin911 has offered me something that I can measure in the morning and return to him before the evening, so I'm taking him up on the offer and getting it welded by someone who knows what there doing.

The place I went to was an exhaust shop so you'd assume they would know what they're doing.

Ok, so we took it and spent a couple hours, 3 holes in the welding on the "good" side, a few centimetres taken out of the other side and we smoothed out the area between the flanges and the cat, one side its even, exhaust headers to cat its a tiny step down (fraction of an inch, we decided to leave it but to smooth it out).

Lining it up without a jig was a bit of a challenge but its perfectly lined up.

So its in the car now and done properly, I strongly recommend against get any work done by a particular shop on Chesterville Rd Moorabbin near the intersection of Keys Road.

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..

      R33 GTR running -9 with no tune

      By Murray_Calavera · Posted

      I don't understand how this hasn't boiled down to - Upgrade the turbo when you have everything required. ECU, injectors, fuel pump, turbo, etc. Do it all at once.  If you don't have everything required, just enjoy the car as it is and keep saving up your pennies.

      Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.

      Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it

      Coolant leak?

      By Duncan · Posted

      Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
