So as most of you know I’m the one with the BMW 318is/ M3 with 318 chassis swap <— to put it simply. She’s going away for the winter months and Im not just gonna let her be. Soooo since the end of last winter my friend Chris and I ripped apart a fully working 318is I wanna do something big to it this winter Money is a concern so I wont be able to do anything too expensive but Im thinking of fabricating a rollcage from prebent and cut tubing or having a pro shop do it. Maybe start working with carbon fiber and make the interior look more like a street driven race car and not just a track rat with the insides ripped out (and Ill maybe move along to structural things such as hoods, fenders, and roofs later). If I can figure out a way to make a side exhaust that’s legal for my car, which would include having it run through the cabin, I may want to try it but would like to figure out how much back pressure is needed to have the engine running smoothly and would like to measure the back pressure of the exhaust when its done to meet those specs.
I also have an '89 BMW 325i (e30) which I was thinking bout turboing and practicing building a turbo system for. Since it has 260,000 miles Im not too worried bout the engine and the turbo my friend Chris has is a T3/T4 turbo, HKS blowoff valve, and some other goodies. I dont know a whole lot bout turbo’s so this project is gonna take some reading up on to get it to work right and efficiently.
I know some kids up in B-spa that run some sick BMW’s you should check him out on a rebuild. He has dynoed at synapse over 400hp. He built it up from the ground up. Hit me back if you want to know more.
oh and kosta, in order to do a side exit like you said you’ll have to cut the floor pan, and to do that you’d have to invest in a pretty serious cage (like $5k+), but you’d be fine when it comes to backpressure with just throwing a resonator or two in the mix…or god forbid a cat :rofl
I don’t think he has the heart to put it away yet, saw him driving it last night, waved to him and I just got a wierd look back, and then I realised that I’m not in my car so he didn’t recognize me
Kosta, what the hell do you keep on the top of it in the parking lot anyway?
Lets get some pics done, I’ll get the camera out before you have to put it away, it’s not like you live far lol
i’m probably gonna go side exit on my e36, just because its not a daily driver. i’m not going to mod the floor/ skirt either. yeah, the exhaust will be madd low, but i’m planning on using oem style flanges, so i can just slap a regular catback on there if it doesn’t work out. i’m running the supersprint trackpipe on there, so there is a decent sized resonator. probably as close to quiet as its going to get with such a short run of piping.
