I have a 1993, R1 25th anniversary 13B. I've converted it to a ported single turbo. I'm looking for opinions as to whether to keep the original parts or get rid of them and what they might possibly be worth if sellable.

 

No idea what a "25th Aniversary 13B" is... but to your question...if you've gone single and don't even have the sequential system, I wouldn't bother. That said, I saved mine. mostly because they (currently) aren't worth much more than the cost of shipping and I had the storage space.

 

keep original all parts. sell them at a swap meet, craigslist, e bay

 

[ thanks for the advice

 

thanks for the tips, I have someone interested in my original rear catalytic converter, a factory one from Japan is over $4000, any idea whats a fair price to charge for my old one?

 

Rear Cat? From the factory, there was a pre-cat and main cat. The pre-cat was as the name implies and integrated into the OEM downpipe. If you STILL have one, it should be removed. They were added only to aid COLD start emissions and were known to collapse with age and plug the main cat...which could damage the engine. They also GREATLY increased underhood temperatures which baked plastics and rubber...i.e. solenoids, check-valves, wire insulation and hoses, and reduced life-spans of those components. Of course you can save it if you're **** about such things. But I think owners don't have any problems with emissions testing with just a downpipe (and a decent main cat). Preferably the DP is heat-coated or wrapped. Adding a quality DP is one of the few two-for-one modifications IMO. It's a reliability mod AND a performance mod
Not sure what the value of the used OEM main cat is, sorry. But I doubt it's anything near $4k.

 

Ok thanks, by rear cat I meant main cat, my apologies I'm still learning. The car has been modified quite a bit, there is an aftermarket main cat only in the car now. An aftermarket catalytic converter kit only runs 200$ or so but to get a factory one from Japan through mazda is 4K, I confirmed it through a number of dealerships which is ludicrous. I'm never going back to original and people are inquiring about buying my original parts, just want to make sure I'm not asking to much for any of it. I appreciate all the advice offered by those who know a lot more than I.

 

keep the original parts, or give to another fd owner for spare parts.

 

My gut feeling dictates I'd keep them as long as I had the space)

 

If you already went single turbo then you might as well do some more bolt on mods.
