carburetor convertion
« on: April 07, 2008, 05:39:50 PM »
Mga sir, newbie here, My car is mitsubishi galant lambda which is running 4G52 engine.. Dual weber side draft yung nakakabit na carburetor.. Medyo malakas sa gasolina kaya balak ko palitan.. Wala na kasi yung original nya na carb "intake manifold lang ang nasakin" kaya i'm planning na bumili at iconvert ang pang toyota 5k na carb para sa engine ko.. May nakapag sabi kasi sakin na mas makakatipid daw ako pag yun ang kinabit sa engine ko.. Gagamitin ko nalang yung dati nyang manifold pagagawan ko nalang ng spacer para magfit sila ng 5k carburetor.. I'm not looking for more HP nman basta makatipid lang ako sa gasolina without changing my engine.. what do you think mga sir? patulong nalang po.. thanks.  :)

Just change your jets to smaller ones if you want to save gas. Where to source them that I wouldn't know. Some people would solder the jets and then use drill bits to "re-size" them.

IMHO masyadong maliit iyong 5k carb sir. it is designed to run for 1500 cc displacement engines. totope ka lang which is bad for the engine.

why not search for a stock downdraft carb for your car? for sure meron pa yan. kung ala talaga, better to use the ones coming from 2 liter engines like 18r (for toyota) or 4g52/4g63 (for mitsu). then slightly jet down accordingly.

tago mo lang iyong sidedraft weber since it commands a fairly high price nowadays.

Sir, We just tried that.. we solder the jets and used needle at the same time to make smaller holes.. Tumipid sa gasolina pero konti lang.. I think side draft carbs are only used for racing.. not for daily driving.. kasi masyado malakas sa gasolina.. But I admit, weber carbs are very powerful.. lakas humatak.. sarap pakinggan pag rev.. Anyway try ko narin maghanap ng single weber side draft manifold para sa 4G52 pero wala akong makita.. nakakita kasi ako sa web, isang weber na side draft lang ang nakakabit sa engine nila.

I thought kakayanin ng 5k carb yung engine ko..
Mga sir, meron pa akong isang carb dito.. solex na pang saturn pwede kaya ikabit yun sa astron engine ko?

if you have relatives in the US you can request them to order some weber carb kits for you.

side draft carbs offer more tunability versus the stock, downdraft carb. marami rin nagsasabi na pag isang single side lang kinabit mo mas lumalakas sa gas. if you want a simple solution you may want to look for a weber progressive downdraft (32/36). eto matipid ito sa gas if tuned properly but will give you the power that you need.

any after market carb can be made to fit for newer engines. just make sure you have the ff:

1.) intake manifold to match your engine and carb - most of the time, you'll have someone fabricate this for you.
2.) have the correct jettings to match your current engine displacement and engine mods, if any

if tuned correctly, matipid pa rin naman ang twinside eh. pero for your engine i'd suggest the 32/36.

most of the aftermarket carbs pala are based on old design, so ala sila nung mga solenoid for idle up. may idle up circuitry, pero vacuum operated. sa madaling salita, mawawalan ka ng idle up pag nagpalit ka ng aftermarket carbs. i suggest that you prepare for this, kasi tataasan iyong idle mo para when the a/c compressor kicks in di mamamatay ang makina.

Like what everyone said, the 5K carb is too small for your engine. It simply will not run properly with that carb. Medyo mahirap na humanap ng surplus carb for the 4G52 since the cars that used this engine in Japan have been crushed by now.

Best bet is to run a Weber downdraft carb conversion kits. You can source them from Classic Cars specialists in the US.

Upon my research matipid nga sa gasolina ang weber progressive downdraft (32/36) but give's you the power you need.. kaya lang hirap humanap ng ganitong carb na surplus.. mga magkano po kaya surplus nito? may alam po ba kayo na nagbebenta ng surplus? try na namin yung carb ng satrun, wala kaming makitang alloy na spacer kaya nagpagawa nalang ng kahoy na spacer yung mechanic.. pwede po ba yun? update ko po kayo sir kung ano mangyari sa convertion namin ng saturn carburetor to astron engine.

saturn carb baka bitin pa rin kasi 1600 cc pinakamalaki niyan eh. as for weber 32/36 abang abang lang sa mga online forums / old school forums kung may magbebenta.

if walang makita na carb for your engine try 18r or 21r carb na pang toyota. iyon ang mas sakto sa engine mo then try replacing main and secondary jets with smaller ones. try mo mga 5 sizes down as a start.

i wouldn't advise this on your 20r engine. this will make the a/f mixture too lean, which may lead to premature engine wear.

suggest to replace your jet (main/secondary) 5 points smaller, granted na stock pa rin ang sizes ng jets mo.
