I should have pulled it out to get ready and looked for part numbers I suppose. If it turns out to be the same as the one the guy is selling, I'll know for sure.

I don't think there are any differ ...

How about this...does anyone know if the secondary fan (the one that comes on with AC) is equivalent to the single fan for non-AC cars? I THINK they're both single speed, right? As opposed to the dua ...

The while-you're-in-there parade has begun. I'm replacing my water pump (because even though I bought it, I stupidly decided not to do it about 9 months ago when I did the timing belt. Guess what has ...

That does sound nice, but it seems pricey for a cat-back single exhaust. Also...+25/+29 hp/torque? Without touching the cat? Seems...questionable...

If you want off the shelf 944 turbo option https ...

Is there a recommendation for replacing that rubber sheath? It may not cause actual problems but it doesn't look very good.

Preferably something that doesn't require disconnecting the lines...lik ...

944 turbo (951) rear section (catback) is a direct bolt-on to the 931.
I simply empty the cat and replace the rear section with a used 3 ...

You're right, I did. Probably poor word choice, but it does appear that's the only way to do it now.

You mentioned 'custom' in the title. Custom doesn't come off the shelf. Just employ a metal guy ...

So looking at various parts diagrams, etc, the ROW has a silencer of some sort where the US version has the cat? My problem, and maybe I'm reading this wrong, is that in the US, the cat is where the ...

I had a couple turbo RX-7s in the past, and I know one of the things people always did was reduce exhau ...

Fellow 928/931 owner here. Although my 931 was in good driver shape when I got it, so nothing near as daunting as the task before you. I'm no great mechanic though (I'm currently getting my butt kicke ...

Sounds like a great idea to me

With these cars becoming older and increasingly rare as accidents or part outs, is there any renewed interest in a 924 registry?

This is the only one I could find ...

Another thing to do, after you take care of some of the basic up-front stuff mentioned above, but definitely before you push it, is to get a boost gauge. It's up to you if you want to keep the stock l ...

I took some staring and thinking, but once I had the schematic straight it all made sense, more or less. There's a lot of misinformation out there about exactly what relay is needed. In this case, I ...
