Yes I searched, and couldn't find much about identification.

Im wondering if these vacuum hoses are aftermarket if anyone can tell. They are really purple, but for some reason, my camera will only show them as blue. If so, should they be suitable for rebuild? (8000mi I think) Im under the impression that stock hoses are black. But I was also told my motor is a '97, and not sure what hoses look like out of series 7 & 8.

Thanks!

 

those are Aftermarket hoses. If they only have 8000miles on them there fine.

 

Is it possible to tell specifics by someone experienced? Or is that kindof like asking what brand is the needle in the haystack?

 

Yup those are aftermarket, hard to tell what make... You could try and t
find out by doing some back tracking on your engine.


They should be fine to use at 8000miles, just make sure the zap straps are good and tight. I would replace the check valves though..


Dale Clarks viton valves are the best option, and for 15$ you cant go wrong.

Hey thanks for that link and reccomendation! I dont see why they shouldnt be as described. Im ordering a set now.

 

How exactly does one go about back tracking?

 

Actually I just made a discovery. Stamped into the castings, after a bit of searching, was N3A1. So much for it being a 1997 motor...

 

The hoses probably fine. But for $150 you can order a kit from here (in your choice of colors) and you don't have to wonder. http://www.hosetechniques.com/produc...oducts_id=2803

 

this is where i got my hose techniques kit from for less then 100.00

^ I can't remember where I bought my kit now...been too long. But I thought $150 was pretty high. Wierd that buying it direct is 50% higher, but thanks for the correction.

 

Thanks for the links. FWIW If anyone noticed, the factory site said theyd beat any advertized price, meaning they should come below RX7Store's price, if anyones interested.

After reading stories of boost issues and a bit of searching, Viton is the only hose Ill consider using. Not saying that silicone is bad, great for the price, but like most all things you get what you pay for.

 

Not necessarily. If you use GOOD quality silicone, it will last damn near forever. The Viton is nice, but it's harder to work with and costs quite a bit more.

I've been using Hose Techniques vacuum line for about 10 years now, the stuff works great and lasts forever.

I really haven't seen a good reason to use all Viton for the vacuum lines. The PCV system lines that are always going to be seeing oil vapor, it's a good idea, but for the rest of the lines, use silicone.

Viton is stiffer and not as flexible, and is a little harder to work with. Also, the cost difference is pretty significant, where the money you save could be put towards something you'll get more benefit from.
