I wanted to see pics of turbo kits that people have installed on their E28's...any kit at all even ghetto-fabbed homemade ones. And for TCD guys what kinda power and 1/4 mile times are you showing, what boost level, any additional mods that aren't included in the kits, and what parts on your engine have you built-up or reconditioned?...the reason i ask is because I'm saving up for the TCD kit and want to know what things people have replaced or have broken due to the dramatically increased power output(driveline, drive axles, cyl head, anything)?...and anybody blown up anything as result of turbo?...curious as to what to expect and precautions to take before going the turbo route...thanks!
PS- basically i'm also trying to get an idea of what a TCD S2 makes the E28 feel like(what cars have people driven that somewhat compare to the feel of the pull and what kind of cars have people "owned" ha)

I'm running a TCD-s2 with MLS head gasket and ARP head studs. MS2 with EDIS engine management. It made 310whp/345wtq on a very hot day at 13 psi. Don't know 1/4. I've messed around with a little more boost, but I put it back to 13 for the time being until I get more time to mess with it. I've had it on over a year now with several track days. Haven't broken anything; I might change the rear half shafts b/c the boots are all torn up, but that's just because they're old.
Even at 13 psi it will beat most things on the street. The feel of the car doesn't really change much; it obviously handles the same and the power doesn't come on hard at all. Very linear, just the same old car with twice the power. Great hwy cruiser, fun to do 40 mph burnouts in town.

I am running a TCD manifold and turbo. I blew my original head gasket about 1000 miles after I got the car running. I have an MLS head gasket now and havn't had any issues for the past 3000 miles. I put together an air-air intercooler setup. I am running 8psi right now, but am going to be turning up the boost soon. I am running MS2 extra for engine management. The car is a lot of fun to drive. I haven't been to the dyno yet, but have plans to go soon.

I personally don't have much time to search the 23 or so pages
Then you don't have time to turbocharge a BMW. Once you finally get someone to tell you what you want to know, you'll still need to do the research to make it work for YOU.
I was running a TCD stg 2 with a PIGGYBACK and it didn't work out. It wasted 2 months of my summer going back and forth with the engineers on why my coil ignitor kept burning out. I am currently in my 2nd month or so of learning megasquirt and just got the car started about 2 days ago. So I geuss the only info I can give you is this;
1. Don't mess with piggyback computers
2. Try to treat your resource of information with a little more respect.
3. Learn what it takes to complete the project so when someone asks you about your setup, you don't sound like a "TOOL"
Here's a pic of my setup:

"Dont expect to demand info and have everyone search and bring it to you." Turbodan
well genius, i asked people to write what they themSELVES have done to their own car...maybe i have some crazy super power that allows me to know what's under hood of my own car without having to do research and was just expecting too much out of people, but i'm not sure...and i'm not pointing a gun at anyone here either, so if you wanna write what you have then write what you have...if not...don't waste ur OWN time!

1. Fill your differential mount with poly to avoid your differential attempting to mate with the pavement with nasty results.
2. Make sure your engine has healthy compression and is in good overall condition. If it's healthy but high mileage and still has the original headgasket, replace it with either stock or MLS and get head studs.
3. Be patient. Take it slow. Do your best to understand what you're doing before as well as you can before you do it.
Follow these steps and you should avoid major calamities.
Oh, and please put you dong back in your pants. We're not interested in measuring it and we're not having any pissing contests today that I'm aware of. Thanks.

My car pulled the center section through the mount on a full boost pull in second gear. 10 psi, non-intercooled. Did some serious damage to the rear cover of the diff and to the mounting points for the rear subframe on the unibody (tore one side completely free, ripped the other).turbodan wrote:This was not a problem that I was aware of.

It's precautionary, yes, but these cars definitely have the torque to accomplish impressive failures like that. Filling a diff with poly is much easier (and cheaper!) than the repairs I had to get done.

The mount. Your average e28 doesn't have enough torque to pull the center section through. Turbo cars do.
Cracked the drain plug right off the rear cover. Ugly. I never found the drain plug/boss. Kinda wanted it for a souvenir.
I never took any pictures of the damage to the rear unibody I'm afraid.
