A top tuner mechanic from coimbatore told me ECU is not a must do set-up for a mpfi-engine while swapping the engine!
Fuel pressure regulators are enough for the job!
We can set the amount of fuel flow to the intke manifold by a regulotor switch!

Can anyone suggest me which is the best fuel pressure regulator for an Zen mpfi if am going for an esteem engine swap?
Please Help!

I dint get it, you want to swap an esteem engine into your mpfi zen, right? The ECU for both the zen and the esteem are the same. Its only the engine that differs. The engine block is the same too. So you practically dont need to change the ECU or wiring. Keep that intact and just go on for the esteem engine.

Happy modding,

I suggest you look for another "top tuner mechanic".

And it is news to me that both a 1.0l and a 1.3l engine share the same ECU.

FPR do not make such a vast difference else a 10k mod would suffice to all of us!!!
get a new tuner or maybe you misunderstood

I would suggest you consult another tuner so that your doubts are cleared. As far as i know there is no such FPR for a zen. Its common for a few models.

Guess the FPR for a zen should suit the esteem as well.

Hey he is a well experienced tuner, and have been tuning Inrc cars, both for MRF, JK and sometimes red rooster! What he told is that the displacement itself make the difference as zen is 1000cc and estemm is 1300! if i dont fix any puel regulators i may run my engine short of fuel there wont be enough difference just by changing the half bottoms!
Ecu may be same there must be difference in the programming in it, the amount of fuel suplly is more in 1300 cc engine when compared to a 1000cc zen engine!

Thank You!

So you are going to swap your Zen engine to the Esteem engine and keep the Zen ECU and add a FPR to increase the fuel flow to the Esteem engine Right?

If so why cant you get the Esteem ECU with your swap and avoid the FPR?

Surely the Zen ECU will be waaaay off in fueling and timing the 1.3 Esteem.

Good question! If i go for a Esteem ECU i must fix a esteem head also! Am not swapping my engine completely! Am geting the bottom half only, which include the cranks pistons and rods!
A full esteem engine will not come under my budget!

I'm not sure about fueling, the timing is the same for both i think

Timings are almost same for most suzuki cars! Thats the advantage for the suzuki cars for swapping the engines!

so u are just going with bigger internals! That is like a stroker kit. Then what you said makes sense

Bigger internals?? you mean the pistons and rods?? I have carry out a slight modification on these things!
