[hanadin]

Hi Guys....

Just need to know how does a Turbo work on carb. engine is it same as on EFI engine.....any workshop rekomended to do custom Turbo....in which case i buy the part the provide the expertise.Tq

 

[rajie]

i know the old galant is cab turbo :) :)
what engine are u using bro ???
i know alot of cab engine always for webers some use twin webers very powerfull also can fight with turbo with right setting but petrol makan damn alot

i just did some research regarding turbo setup on carburetor engine.
basically it is divided into 2 types, either suck or blow.
For suck/draw through setup, turbo suck air from the carburetor. (carb->turbo->intake)
For blow through setup, turbo blow air through carburetor. (turbo->carb->intake)

don't dare to comment much since i believe there are lot more ppl know much than i do.

i would agree on that , good post
if i were to make a carb turbo, i would obviously choose carb->turbo->intake
but there are some drawbacks too,
first things first , this method is the easier way because you can use any big carb to make this setup , the blow through setup requires you to have a Turbo Capability Carb which detects boost and supplies more fuel. The Suck/Draw setup sucks air + fuel , the more air , the more fuel its gonna bring in , but the drawback is that you gonna suck fuel + air into the turbo which might not be that good for the turbo's seals and compressor wheel.

I already done before since 2004 with a fiat 1.8L carby turbo.with std carby and stock ignition u have a trouble when boost come in.Carby jet is not enough to flow the fuel.What we do we remain the carby and add the MT4 fuel controller.we fine with fueling and retard timing with MSD boost ignition controler.Low budget but good whp.SUCK or FLOW it is not big deal.Huge....

Bump: Base turbo u can use a small turbo...Awesome in USA carby turbo can make 9sc

Sample for u..Fast boost.

How much is the total cost for you to do the Turbo on your Fiat?I was planning to do on my car...but don't laugh la...it my Tiara...i do see a posting regarding the BOT for any car but the starting price is around 5.5k...that is without any extra modification....i was planning to buy the part separately and put 1 by 1....that why i need to know how a Turbo work on carb. engine. I was thinking of using a Mira turbine or a Starlet....since i can get boost maybe 0.5 or 0.6 bar...depent on setting i suppose

I've seen some guys customize a turbo setup for an old Jag carby engine. They converted the carb to a throttle body injection setup! The engine had twin carbs, and the jets etc have been removed and replaced with dual 550cc Mitsubishi Evo injectors. The throttle butterfly axle had custom fabricated "ears" that attach to external throttle position sensors. The whole setup is handled by a standalone Motec ECU. Damn expensive for the owner to mod, but definitely can be boosted because if you were to use a normal carby setup, the carb might stop drawing in fuel on boost. Have to at least add a fuel pump and change some stuff at the carb jet to ensure fueling continues under positive pressure.

sometime ppl say Carby rubbish..to me no.Everyting can making with a good set up.

sifu,

mean... the mixture may not be good to the seal of turbo and the compressor wheel inside the housing of turbo if the turbo are after the carburetor??

hehe, u r advising us 2 use carburetor after the turbo(carb -> turbo -> intake ) rite?

sorry ya..
poor in English and really wish could gain more knowledge about automotive...@@

I would like to know...
there's requirement for inter-cooler for carburetor turbo-charger engine??
*I guess yes since Kancil/Mira are using inter-cooler for their non-injection engines rite??

sifu2, pls correct me....

drawthru diff frm blow thru, in terms of idle (since turbo mounted on intake side of turbo what).
carbon seal prevent frm lube oil sucked frm turbo during idle.

unless you fancy smoking, of coz
