Hi
I whant to give more power to my 325IX 1989 but before buy i have some question to people that have modificate his bmw.
1: I whant to put a camshaft, i know that shricks cam are the better but very $$ did you know place to buy aftermarker cam, or other cam that are cheapless but have a good performance upgrade. ( i know that bwm2002.com rebuilt original camshaft forbetter perfoamcne.. does is good?)
2: I need to upgrade my exhaust if i whant to have better performance with the camshaft. But does i need to change all the exhaust line or just the cat back and the headers will do the job?
3: If i can use my orgininal line, does it will fit on a supersprint or ansa catback? (same input size)
4: What is the original size of the double exhaust?
5: Does its true that i need to buy a reel exhaust for bmw or go buy a standart performance catback with a Y can do the same job?
Finally, what better compagny or web page to buy for a good $$/performance that can ship to quebec city. (used or new)
1, don't buy a regrinded stock cam. schrick or bmp would be the way to go. bmp has a decent selection of cams.
2, start from the back and work your way foward with the exhaust. if you plan on headers, then first you'll need the catback, and a better cat. i run a custom 3" from about 2 feet before the stock cat.
3, i'm not sure
4, 1.75"
5, you can buy a custom fit exhaust, more money then its worth imo, or get a custom one fabbed. you could get a custom exhaust from the headers back for the price of a premade catback.

why no regrind? i was talking to a guy who grinds regrinds and ones froms a solid core, he likes the regrinds of the euro cams more because they are made of a harder metal then all the aftermarket cams which means they wont break or wear out as quickly so as far as i can see if you get a competant guy with the right profile there hsould be no downsides. fortunatly i know an extreemly compentant guy with an awsome profile and iv been running these cams for 1 month and a half and they're the best thing that ever happend to the car.
you want chill hardened billets, which is what you'll get with most decent companies. i would personally have a cam ground from a blank rather then a reground stocker. after all the stocker starts life out as a chill hardened billet blank.

yeah but the properties of the cams are different. the stock bmw ones are harder then any aftermarket cam you can buy i guess its all in prefrence that and buying from big name you dont have to worry about finding somone reliable... fortunatly i found reliable and my car is still way way way way under air care limits
SO what i understand is take a shrick cam with a ireland ingenering header and a costum exhaust, not important to spant money on a supersprint catback.
IIF somebody have or know who have performance cam and headers for very grood price, used if nessesary...
umm depends i got mine done for 350$ canadian but he didn't make any money on me so normaly like 500$ or so maybe al ittle more? id have to check and its only a single cam i can call him if you want
maybe arround 403.3884 US dollars give or take not sure on the price ill call him and check tho are you interested? it might be more depending or less depending on the discount i can get.
