Injector upgrade for my M800 -
Maruti 800 came with very small injectors. My M800 turbocharged setup was running on 172cc Baleno injectors till a few days back.
As i was upping the boost, it was doing good untill i did a few longer pulls on 3rd and 4th gear and it felt lean. This is with the injectors wide open. So....as expected I needed bigger injectors to get it running better on high boost.
After some internet searching I found some suitable OEM
injectors that may work well. Fitting these injectors needed some changes/mods to be done on the fuel rail bracket etc. to accommodate larger injectors. I always wanted to try out one of the denso variants that came with 12 hole vis-à-vis 4 holes on stock injectors. There was one problem though – it was expensive and not very common. Finally , sometime back I got myself a set of Denso 12 hole injectors.
The Baleno 172cc injectors were upgraded to these Denso 265cc injectors a couple of days back. The fuel maps were scaled down to get the fueling right for idle and low boost and car fired up and idled perfectly. Needs more tuning on high boost cells but the power delivery is much better than before.
