Your best bet is to get onto E30tech.com. They're the boosting gurus.

The problem with boost is that everyone says, "Oh I'm not planning on going higher than X psi..."

Then they drive their car and come back a week later saying they want more boost. It's addictive. But the point I'm trying to make is that there's enough knowledge and experience out there to pull from that you're better of spending your money on a DIY standalone kit that gives you the ability to tune for more boost than you'll ever be able to run than to spend money on a chip that's only good for one boost level.

I built a DIYPNP kit from diyautotune.com for my tuebo. It cost ~$500 including shipping + supplies (a cheap soldering iron, solder, and some wire). The kit was easy to build, you can do it in a weekend, and they even have base maps for a turbo 325i running 15psi which you can use to fire up your car.

Assuming have a super eta (motronic 1.1) or you've done the "i" conversion to your eta (motronic 1.3). There is no PnP kit for the 35 pin motronic 1.0 that the standard eta cars ran.

Yeah that 4800rpm redline isn't doing you any favours. Find someone parting out a 325i and get the parts you need to do the "i" conversion.

I've met him and already talked about this. Apparently he doesn't feel the need to listen to guys that have already built the cars.

i have a 85 eta, not much can be done on these motors aside from the i conversion. best bang for the buck... LSx conversion. or convert to a GM 3.8L, which im thinking of doing.

It's definitely doable. You can set-up an eta on stand alone, there's just no plug and play kits for them. You'll either have to hack up the wiring harness or gut the stock DME and work at fitting everything into that box similar to this...



FWIW, if all you want to do is a low boost application I'd recommend just swapping in an S50 or S52 motor instead because you'll make similar (if not more) power and still be able to insure the car. An aftermarket turbo is an instant denial of coverage for 95% of insurance companies.
