Hey all

While getting my car serviced on the weekend I tried to get a front pipe installed that I bought off SAU. unfortunately the side of the front pipe that bolts on to the cat has a 3 bolt configuration and the cat has a 2 bolt configuration.

Now I was looking at high flow cats, that's what the previous owner was running, but I could not find one with a 3 bolt flange on the one side.

My question, anyone know of a cat with 3 bolt flange on the front pipe side?

Or

Can I just go to a exhaust shop and they'll be able to mock up a adapter?

Thanks

Yeah you can cut the 3 bolt flange off and weld on the normal 2 bolt with no issues, but 3 bolt flanges are better at creating a good seal especially at the larger pipe diameters.

So the choice is yours, go for a 2 bolt and have the common flange type or go for a 3 bolt flange which will be the better connection.

Don't know of any cats that come with a 3 bolt flange, I struggled finding a 3.5" cat with a 2 bolt.

Most of the hi flow cats don't cone with any flanges and are just basically a pipe and that's it, so getting one of them and getting the flanges you want welded on would be your best bet.

Also as BSA stated,, there is no harm in getting your existing cat modified to a 3 bolt to suit rather than having to purchase a whole new cat.

    • That's a given!  Bit hard to powdercoat it properly without removing them! 😁
    • No detail on compressor or turbine sizes, which doesn't help with housing size selection with that kit. However, from SR20DET mucking about and money torching perspective, a GTX2860R Gen 2 w/ 0.64 (46mm inducer) will do ~260kW on E85 about 1.5bar of boost. All in before 3000pm, which cause a gearbox to shatter. Now imagine the same turbo, on a modern motor with an extra 0.5L of displacement, and heaps of cam timing adjustability (not an on/off affair like the Nissan shit boxes). If this was my car (which I would never own or consider buying, ever!), I would go for a nice twin scroll setup, and a G30-660. Gates plumbed back, no silly shit. Lean on the cam timing, big displacement to create a flat-ish torque curve.  
    • Do you plan on using 98 or e85?
    • This should be pretty easy. 200rwkW is just about the max power out of an RB25 stock turbo. So, 12ish psi on a 2.5L. That boost limited mainly by the prospect of seeing the turbine in the cat after the smoke show. A steel wheeled equivalent would likely happily do ~220rwkW at something like 17 psi, where it would probably be bumping into the usual limits of such a sized turbo. These things have like a .48 rear. You will not need the 0.86 rear. The 0.64 will be fine. In fact, if you were looking at various mid-200rwkW options for RBs, most of them would be in a 0.64 rear. So, I think you will definitely want to be no bigger than that for a same sized but probably even more efficient (at making power) modern engine.
