Title: BWA 370bhp+ What is needed?
Post by: james on January 31, 2012, 11:00:00 am
I would like to push my BWA engine a little harder,  What would be needed?  rods and both cams or just one?  anything else?

Or i put an s3 engine in.....  can’t decide? :chicken:

S3 or ED30 engine would be the way to go and probably cheaper in the long run.

Perhaps more cost effective to use a stage 2+ Cupra / S3/ ed30 engine

you could sell me your KO4 and associated parts from your BWA to assist in financing your big BHP new engine.

Looking forward to seeing the car at JKM

The R-Tech lads have a K04 equipped BWA pushing out 370bhp - they recon the engine does it no problems!

just picked up a golf r engine for 1.4k  (CDL engine 11k on the clock) With gearbox.
Does anyone know if that will work with a S3 ecu?

Hi James, there will be some slight variances with the wiring and coding but it can be done. It also depends on the year of your s3, what year is it? Where did you get the engine from? Possible change of the engine loom aswell.

i have got a mk5 GTI with a BWA(with ko4) engine.      I brought a S3 ecu from ebay as i was going to install a BHZ engine.

I wentt down the local scrappy and they offerd me this engine for 1.4k with gearbox but with no loom or ecu.

The engine was from a Golf R20

can i use my BWA loom?

WMI makes no power on its own merits it need to be mapped in to get nice gains , its used for efficiency to run a leaner AFR, strong advance tables and higher substained boost.

It not what we do, with James mk5 I was helping him out so we could get some mapping R&D time on the dyno with WMI.

18/19psi to the red @134bar rail pressure with WMI 18-21deg advance is the way forward.....  :driver:    It would be if I can get rid of this stupid EPC fault.... :ashamed:

I meant an overlay graph from when you originally mapped the k04 to results after wmi installed.   :smiley:

I can't see why not, I have an BWJ (Cupra engine) with AXX loom and AXX ECU.  :happy2:

You still running the GTI map sensor then? 1.5Bar limit?   as when i put the S3 map sensor in i just get fault codes.

I have the Cupra/S3 sensor but not fitted yet, but i assume it won't work unless i find a Golf R ECU or ED30 ECU for my car  :sad1:

You can use the old loom fine.  The engine is physically the same.

Just use the old map sensor.  The s3 map sensor may need scaling to get it to work properly.

I can get 21mm wrist pinned forged rods for the s3/ed30 engine now too.

The CDL has the 21mm wrist pins all ready does it not?
