Just use back the blardy 4G15 TB at the moment...why you wanna put something not compatible !!

4G1x anf 4G9x engine CANNOT BE ROJAK.....most of 4G1x is SOHC except the super rare and special version 4G15 DOHC which you can fine in one of the Lancer model but then it would fit ur SOHC as it's 2nd generation 4G1x engine. Timing belt was on the left hand side type...

I actually prefer to use back my Injections rather going for carbie.... but what to do.... to get a TB for my engine is dam difficult.... if its brand new its wil cost me
6-700 if 1/2 cut shop 1 week warranty only.... some mechanics claims that this MMC version TB is very fast gets spoiled....

I realise that ... my frend also using Carbie... in terms in pickup and oil comparing wit my car... its about the same... some more i feel its more better perfomance than the injections...

so guys.... can anyone tell me... what are things i needs to but for me to convert it carbie??
Do anyone have carbie 12 valve??

Theres nothing to compare.

If u want performance, cheapest way is performance carb.

If u got alot $$, you should have bought a sports car......

Modding a EFI engine into performance requires alot of $$$ and yet u may not beat a tuned carburetor.....

4G15 got its limit, play n enjoy your car. Otherwise change engine or change car.

Where got ppl take a COW and a HORSE to diffrentiate thier capability wan ?

LOL

reason for telling u this is, i am carb user for bout 15 yr plus, never had a chance to go injection due to financial constraints cos transplanting an engine needs helluva lots of money, change this change that in the end money talks.

i am a user for 1 series engine for the past 10 yrs, i modded till nothing to mod ( i mean engine internals ), even blow up 2 engines in those years. u tell me, what else is there to talk about this engine? injection n carb?? of course there are difference, injection gives u better fc, while carb engines can suffer on fc and carb engines doesnt perform during hot & humid weathers, while injection still can give u the push, carb's can rev like nobody business, while inj have certain limit...wat else u need me to comment??

u are still new in engine mods, there are many things to mix & match on ur engine, thats for u to find out urself....
