Borg Warner S200 on 3B engine pls help

[sano88]

Yes it is

[sano88]

restrictor didn't help. what you think about stage Ic ECU?

[Billman]

what restrictor??

[sano88]

2)Restriction in exhaust, a restriction would have more effect on a bigger turbine wich needs more airflow to spool (enter it's efficient zone/speed)
it was an idea of one of members.
and what about stage Ic ECU?

[Billman]

Restriction NO. About 034 ECU or in general a Standalone ECU i believe it is the only way if you dont want every now and then Custom Remaps on Motronic.

In order to have your car work you must have it remaped. The K24 and this S200 have nothing in common.

Post us a video clip also if you like. I would like to hear how it spools. It must be very loud.

[sano88]

Thank you Billman. Custom remap is fast impossible. I leave in Georgia, country at the black sea side and here are not any tuner. I marked USA on this forum cause there wasn't Georgia in the country's list. and what about distributor ignition?I contacted some tuners from Germany and I was told that it's impossible to do custom remap on my motronic ECU,cause of distributor ignition. And one more question. Are there in a market any stand alone like Ic? I can't rebuild my car on colis.

As I understand it, you will have little or no improvement just by changing to the 034 ECU, you need to be able to custom map this...
as you live somewhere where mapping of the Motronic is not possible (yes, it is possible to map motronic, with the distributor) you will more than likely have to change to an aftermarket engine management system...
There is quite a lot of information on here about aftermarket ECU's, but you will need to map it yourself, which some systems are good for, others are not...
Hope this helps

What I did suggest was to look for a restriction in the exhaust. If the exhaust is restricted (blocked cat or something) the bigger turbine would suffer more from that restriction than a smaller one that can manage to spool even if the backpressure is high...

[sano88]

Yes, and I say thanks. It was good idea and much more better than nothing.
Can anyone tell me what will be suitable A/R for my engine(285ps 3B engine, built with 7a cams ). I will say one more time I can't remap my ECU. or stand alone ECU is only way in my case?
or may be it will be better if I'll write some specifications? here they are:
Compressor inlet pipe 60mm, compressor outlet pipe 50mm
56-trim compressor; inducer 45mm, exducer 60mm
Turbine wheel outlet 46mm, outer diameter 53mm
or
Compressor inlet pipe 70mm, compressor outlet pipe 50mm
48 trim compressor; inducer 53mm, exducer 76.5mm
Turbine wheel outlet 46mm, outer diameter 53mm
wich is better in my case?

YES

If you cant remap what you have, unfotunately you need to map it... Standalone is your only option.

[sano88]

YES

and what about turbines wich descripction I wrote?
