Currently I'm using this engine on My A212 (Mitsubishi Tredia 1600L). The Original engine of this car was 4G32...

Anyone knows that modification?

 

[jombiee]

Yes, if your mech. know what to do
there are a lot of mods on carb, but the best still with performance carb
put on weber bro, plug n play + with 1.8 whooaa.
the standard carb are what type ? have pics ? it might help
I want to know also about this 4g37, I thought i saw one in saga chasis

once I mod myself a twin choke carb, making the second vacum to play sequently with the main choke, its good but kenot tahan the consumption as the car for daily driving, 70% more...arghh

 

[jombiee]

i want to ask all carb sifu inhere...hope this is not a stupid question...
i'm using 4G37 engine and its original carb as well... recently, a friend of mine told me that my carb can be modded to get extra power kick-in while cruising above 3k rpm like mivec or vtec system when it kicks-in. I'd say the feel and surely not the power...

My Qs...

1. What to do with the carb? (i asked my mech but he refused to answer, he just said "bagi je aku buat, ko rasa je nanti carb ko power") keep the ori carb, find another performance carb like weber, mikuni etc, mods on standard carb usually seeting or mod the nozzle, porting(korek) its kinda complicated, make sure ur mechanic an expert.

2. Any side effect on doing this modification? might overdo it, more petrol but no power, petrol guzzler at the end you need to find another carb.
3. How about the FC? common sence - more power more fuel !

4. Is it can be restored easily to standard back if i'm not satisfy with the modification i.e the FC is too high? thats why you keep it as stock & find another carb.

Thanks sifuuss....

i'm no sifu, just wanna help, here super sifu is uncle fred daikor...:_:

if you get the correct psi, you dont need any return pipe.

i`m not sure about other cars, but nissan sunny has a return pipe at the ac pump.
i just cut the pipe, and stuff in a bolt. Done. The ac pump is still fixed to engine but just not functioning.

did i can put back original air filter?

to be safe.. prepare RM1k for a DCNF conversion... ur RM1k would includes the carb itself... installation... the base... a new filter... DCNF is a two venturi carb, u r right... Make sure u have made enough study n research regarding Weber DCNF before making the purchase... there's 2 types of DCNF, the 36 n the 40...

er.. ur original filter ar.. if u want to re-fit it back.. u might need to do some modification on it.... n as a reminder... DCNF's venturi is far more bigger than a stock Asian carb.... make sure the air-flow is good enough to maximize the potential....

cheeers

oic!! wah!! so expensive?? got used 1 ah??? what the different between in the 36 and 40?? which 1 good performance and save fuel??? how much need to mod to put back original filter??

 

[huh?]

ehehehe....yes..it is indeed expansive..since the carb is not plug n play..you will need to custom made the base to fit your intake manifold...just FYI

dcnf 36 = RM650
base = RM100- RM150
installation = depends on your workshop
airfilter = RM200 - RM300
it will come near 1k...plus..you will need an airfilter for it..and the airfilter does not come cheap since carb is quite rare nowadays..it is catching a high price everywhere for the parts..

you just need to cut the original filter housing to compensate the bigger venturi size of the dcnf carb..it is just a simple cut..FYI, i fitted my dgv 32/36 with a 4g13 open pod KN filter..hehehe...

i recon you to go to old klang road...ramly motor works..he's an old timer,respect to mr.ramly..hehehe..n the price is reasonable...
