Done, review will be up.

Your inputs can influence my decision. I am in the market for a used CIVIC but due to my exorbitant usage it may turn out to be very expensive to run. Will it be a good idea to turn it to CNG? Your review on your CNG run COROLLA will be of great help.

Abhi.

Abhi, after market fitments (esp. on engine) is something which very cruical according to me spl. when you need to keep the car with you for a long period. I spoke/visited almost every old/new Authorized CNG fitment specialist listed by IGL and asked for their opinion between Civic, Corolla. Every one was inclined towards corolla and stating corolla takes in the CNG mod very easily and adapt it very nicely. According to them CNG can be fitted in Civic as well but frankly didn't found much people who was very much confident about installing CNG in civic. Why ?? Their plea was Civic is having too many sensors which somehow will create problem in long-term usage, as in CNG some sensors tend to fail in long term usage (I can personally authorize their statement as i had similar experience with optra as well) Civic is a brilliant car and revv happy car only, trust me I am very much happy on my decision. My advise, If you having an exorbitant running every day and you are between Civic and Corolla... Pickup Corolla with closed eyes.

Performance Degrade - I will not say high words, but still had been touching 150+ easily on recent tours to Corbett and Shimla.

So far no problems. The only 'Service' required is cleaning the air filter every 5-6 months. I'd say you cant find a better deal, considering CNG is easily available in your town, which actually is the case in Ahmedabad.

So there you go @ Abhi_Automobile - Its a Go Green from me purely out of experience.

@ Ash : Sorry to hijack your thread mate. Just felt I'd double you on the Go green, Save the Planet move.

Well, I intentionally didn't went for Sequential Injection one... Why ??

a. Too high cost when comparing to Non-Sequetional One, Almost double cost.

b. Engine needs to be re-bored, was totally against it.

c. Engine will be running on CNG only.

d. Not every jerry can repair Sequential one, if in case struck in middle of somewhere.

Well, thanks to high petrol cost I have been on CNG since last 5 Years and enjoyed savings at fullest. Had been using CNG in my last car i.e. Chevrolet Optra without any issue so getting COROLLA CNGfied was obvious.

Had to run around to various installers/authorised showrooms and got a good go for COROLLA being CNGfied. Finally paid a sum of around 34K for BRC CNG Kit + Advance Lambda with 1 year warranty. Didn't went for Timing Advancer on CNG Installer's advice as COROLLA being VVTi which is having advancer in-built. Now after using 4 months I am totally satisfied with the performace, savings done due to CNG.

People may debate why I had opted for Petrol Sedan when I cannot afford one, I would ask those people why do they use diesel when petrol is available. Quite simple, cheaper to run. For me it ain't a question of affording, it is a question of better available options.

People have a misconception of Engine being going on-toss after using CNG for a time-span. Well, for me it went without issue for 1,25,000 Km of saving in my last car. Current owner has added another 10K Kms in the last 4 months without issue. How ?? Very simple logic, care for her and she'll revert back positively. Strictly follow up Maintenance schedule, regular service is the key for healthy CNGfied engine. I have seen 50K ran engine running at CNG being chocked due to im-proper maintenance.

All righty, things are hotting up! This is what I was looking for. How much did you find the Sequential injection for? I guess that once the sequential injection is installed, it still has a 'switch' option between the petrol and CNG mode. I read about the 'engine having to be bored' for sequential injection thing but don't have enough details.

Your CIVIC seems to be doing tremendously well with the CNG installation. Is it the Sequential Injection magic? It will be great if you can put a quick comparo between your two cars. Pics and installation details (cost, time etc) will help.

1.7 Kmpl - 1.4 Kmpl

Do you mean to say 17kmpl instead? CNG is sold in kgs. Did you arrive at this figure after converting it to litres?

MY REQUIREMENT: I will only go for the CIVIC sedan (used). I have already driven the COROLLA quite a lot. No fun in having brand new car CNGied! (just my opinion). If this doesn't seems viable, I might as well go for a new Diesel Sedan. (VW VENTO?, FIAT LINEA?)

PS: This is a great thread and I don't want to hijack it. Just that since you have got your car CNGied, it makes sense to clarify/get details: RIGHT HERE, RIGHT NOW.
