Just found myself a Mosselman turbo kit for the BMW m20 engine. It's a relatively low boost system but should give a bit of a hike power-wise. I'll post some pics once I collect it and start refurbing the parts. The turbo needs a rebuild for a start and as I know absolutely NOTHING about turbos it's going to be a bit of a steep learning curve.
Fitted a new chip from Racing Dynamics today and went for a test run near my home. There's a definate step up in performance and a bit more torque. There used to be a bit of hesitation on light throttle but thats gone now and the engine pulls like a train right through to the redline.
Decided to go up to 195/55's in an effort not to rip the exhaust system off whenever I go over a speedhump. It actually worked and I can finally drive straight home rather than constantly taking the scenic route. Probably save a fortune in petrol too!
Next job is to fit the yellow tint headlamp covers and rear leather back seat from a 6 series. I'm also considering a swap to coil-over suspension so am on the lookout for a couple of front struts please guys?
with turbos it's a fine balancing act. It's a street car, so you want driveability, which a small-ish turbo provides. Going too small is silly, because it will spool too early and the boost is wasted, also choking it at high rpm's. Going too big is also silly unless you want mega boost which it will only provide up high in the revs and give you a very small useable power band. So you want something smack bang in the middle, I think a garrett T34 would be ideally suited as a relatively cheap and tough turbo, or a T3 with the biggest housings they come in. I'm not clued up on the new generation ball bearing turbos but i thing a GT28rs compares to a t34. The 6 banger will provide quite a lot of exhaust gas volume which means you can generally go one turbo up for the same engine size if it was a 4 pot. I'd recommend you to get genned up on compressor maps and learn how to read them, then you can pick one that's exactly what you want The info here is good: www.rbracing-rsr.com/turbotech.html
Just picked up a spare set of front struts so going to do a coilover conversion on my 323i. I'm actually getting the work done by GAZ although I'm yet to decide on spring rates. Anyway, I'll post pics as I go if anyone's interested?
keep the pics coming mate. always good to see the mods as they go along. having nothing but bother with my e21 so it keeps my pecker up to see one like yours! stops me hating my car altogether! saw a little pic of your car in a certain bmw magazine last night. keep up the good work!
ps- any more info on that green one, it looks pretty clean?
I'm going to pick the green one up next week. A friend has bought it and is adding it to his collection of 02's and Neu Classe BMW's, so its going to a good home. It's in really good condition although needs a plate welded on floor pan before next M.O.T. It's such an early car that its actually more 2002 than e21. My orange 323 is in the January edition of Performance BMW Magazine I think? Should be out in a couple of weeks. It should look great judging by the pictures I saw on the camera. The blue 316 is poorly again. The ignition module failed after 40 miles but was an easy and cheap fix at £24. Then a day later the clutch went! Where it's sat around for years the rubber seals on the slave cylinder have hardened. As soon as it started being used again they began to leak. I got a new cylinder for £16 from GSF and luckily they are only a mile or two away from me. It's an easy swap on the 4 cylinder cars as it can be reached from above I think? Anyway, it'll soon be back on the road....I hope.
