Default Engine upgrade for 99' carb. Zen

Hello
I want to upgrade E for my 99' carb Zen.
The option that I have currently is:
1.3L carb. esteem engine

However I want to have an 16 valve engine in my Zen.

I know I can put an 1.3L MPFI Esteem & convert it to carb.
It is more preferred as the gearbox is an easy match

I also want to know that is it feasible to put a Baleno 1.6L engine & convert
it to carb.
Will it be efficient, also what about the gearbox.

I wish to get good performance & on the other hand not to decrease the FE to absolute nothin.

Any Help will be appreciated
Regards

I dont think there is any difference in the grearbox, the head is the only thing that differs in a MPFI vs carb esteem where the later has a 8 valve system and the former has a 16 valve system.

Again no changes in the gear box

You would get both thats why its called a pocket rocket. but in my openion a e zen would be more than enough but again depends on the application, is it for personal use or for drags?

The electronics is a pain and only a competent mech can handle the transplant to be reliable and issue free. So usually almost every one goes for a carbsetup even with a suzuki 1.6 twin cam GTI engine, there is a thread where some one has plonked one in a zen classic.

IMO carb to carb is the best and recommended upgrade. Plus cross platform change would turn out to be quite an expensive venture.

when it comes to performance dont you think the electronics are worth the pain??..cz it aint easy to performance tune carbs too you know..and when it comes to performance carbs all most tuners prefer are the webbers and how many guys are there who can tune webbers?

1) The engine mounts and there is a difference in the gearbox mating but can be done without much headache
2) Make sure the clutch is upgraded
3) If you want it to run on carbs without the wiring you will need to modify the cam to accommodate the esteems distributor
4) You don't need fancy carbs but can do with 2 zen carbs on the intake, could give you around 8 - 12 depending on the way the tune is done

Depends on your mech, and if you do not want to destroy the originality of the car 1.3. Else 1.6 (Note: Make sure the swap is affordable and the donor motor is in good shape)

If you mod the engine from the stock, what happens to the entries in RC? Will that also be changed too? Pls help me understand.

Depends on how u mod it, Earlier (even now) engine swaps were preffered because of less hazzles with the RTO and hence insurance, however now the story is little different unless you know people in the RTO. So a no headache mod would be, to get the head replaced to a better 16 valve or DOHC head with bigger injectors rather that going for a complete swap. This wuld mean a lot less amount of hazzels both in terms aof easiy and tension free mods and RTO insurance guys being taken care off as the engine number remains the same.

If need be carbs can be tuned even better than an MPFI.

I would start my post from this quote , There is a reason why i prefer the no nonsense carb, In india we people still have those old cellphones even if we do not use them anymore, so the same logic goes to cars as well, people like the idea of giving a new life to their old work horses rather than going for a complete new one.

I would like to add practicality, simplicity and reliability can come in in a MPFI only when its factory done or done by an expert, Honestly tell me how many carbs to MPFI conversions have you seen in your life? I would say sreejiths gypsy(mexentric) would be the first one i will see in my life(if i live till that day ). Most of the people dich the plan in the middle especially because of the complex issues involved, this happens mostly with the injection system so people ususally convert their MPI's to Carbs when reliability becomes a major factor, and as far as simplicity goes its not that you just connect some plugs and it starts firing. There are many jugads to be done and ultimately its one of those jugads which gets you in the end. Now talking about practicality, the design which is not simple to implement and is known to be unreliable is never practical. Enough of gyan. in one word go carb.

Hmm so you have been there done that, any ways let me requote my own statement, i have seen such conversions but i have also seen people reverting back to carb after some time due to persistant issues.
