hi everyone

i am a noob

i have a 1993 w201 2.0 8v

i am planning to bolt on a t3 turbo with intercooler and dump valve.

i want to keep the stock cis and just enrich the mixture via the lambda tower.

i have heard from a few places that people have hard gear change with this type of thing. what should i do about this?

anything else to look out for?

You're not going to be able to run much boost with the stock CIS-E
It's not able to enrich enough and there is the chance of detonation damage.
You need to attain an AFR under 12:1 to run about 7lbs boost.
The narrow band O2 input to the CIS-E/EZL precludes this.

How are you going to just bolt on a turbo?

If you want to keep the CIS-E, I'd advise you to use additional injectors with an injector controller the way RBYCC does it . As to the gear changes, first get the car running with the turbo and than see if you have trouble with the gears, no need to dwell on a problem that might not exist. We have a couple of turbocharged 2.0 8v here and no one has complained about the gears so far (some are daily driven).

just in those 2.0 that are already turbo'd, ~ how much power/torque are they putting out? and any with the normal 5 speed manual??

To my knowledge none of them have been on a dyno so no power figures for now. Yes some are using the normal 5-speed manual .

thanx for the info guys

i jus want bet 4-6psi.i dont plan on being a hiway killer or a number chaser.i just want 2 compensate for the serious lack of low end torque. I may even use the tiny k03 2 do this.

I dont want 2 do any major fuel system changes coz believ it or not,i love the old k-jet. And its not cis-e btw.its plain cis.call me old school if u like but i still think its a very simple and robust system thats suprisingly efficient. gotta luv ze german dezign.

Anyway i digress, i have this crazy idea.mayb sum of u guys with experience on this can advise me. Would it be beneficial 2 swop the original injectorz for injectorz frm the 2.3? Would this enrich my mixture throughout the rev range? Or could i lean it out via that alen screw next 2 the dizzy? Then when the revs climb and airflow increases, the fuel output increases at a rate faster than the stock injectors? Am i thinking correctly?

The car has vacuum advance distributor for the spark.should i change anything here?

Oh and i plan on bolting on the turbo 2 my dashboard.that way i wil get the look and feel of a turbo car without the hassles. Just joking.when i said just bolt on,i meant no efi.

For any serious fuel flow u need the fuel disturb of the 2.5-16 injectors won't flow more and there is no need to change them. It's the head that restricts flow. Also be warned u might still run lean in the mid range. I dunno just saying oki

Oh u have the option of fitting a cis head from a Volvo turbo engine. Look into that too. That will surely solve ur problems.

interesting. Thank u

i also thought that mayb things might go lean at mid rpm.like wen the turbo reaches full boost at 2300 rpm. What will the advance be like at this rpm? Is there a vacuum advance reference hose frm the block that goes 2 the manifold? Would the manifold pressure retard the timing and cause detonation? Sorry for the million questions

You have a lot of research a head of you. Retarded timing does not cause detonation. Quite the opposite.

my appologies. I understand now. I need 2 advance the static timing and keep it there or retard it when on boost.its actualy much simpler than i thort it wud b.so will the reference hose at the manifold serve this purpose? I mean,ther wil b the opposite of vacuum in ther when on boost so that should retard it.or is the stock distributor not designd 4 that? And tell me,if i kept the stock injectorz,how much wud i have 2 turn the alen screw 2 enrich the fuel mixture for 4psi boost? About 1/2 a turn? And do i really need bigger injectors for that little boost?

On a cis the injectors almost all flow similarly. Its the head that regulates the flow. U can go for the injectors of the 1.8 four cyl and compare them to those on the 5.6 v8 or the demanding 2.5-16 and u will find that there is not that much difference in flow rates.

thank u so much for the info and your patience.so i should either port and flow the head or get fuel dizy off a 2.5 16v.is there much work 2 swop the dizzy? 2.5 16v are not that common in s.a. Would the dizz frm a 2.3 16v work? Or perhaps a w124 230e?
