[mr_lageenda]

i have i question

if i do some modification on my single cam like
*Port n Polish
*Skim Head
*Skim Flywheel
*Adjustable Cam Pulley
*Use clutch cover 3 plate but no use 3 plate.

which 1 better..??

1-Convert twin cam.(Just Plug in the head)No modified this head.
2-Modified single cam

i need more pickup but do not use 3 plate clutch.Sakt kaki.


Any one can give your opinion..??

My poin of u is to go for twin cam...
No one care bout is single or twin cam...as long as u r 4G93...
Twin cam better performance!!!

1) thumb rule for NA modification, higher compression ratio yields higher horsepower.... but there is a limitation towards knocking/pinging/detonation... recommended to skim, but not too much...

2) since u using back ori ecu without piggyback ecu, use back ur ori 184cc injectors can adi... upgrade fuel pressure regulator to fine tune ur fuel pressure if insufficient at high rpm...

3) good upgrade but i not sure if 4g91 intake manifold compatible with it or not...

i already install my engine
but i have a problem with distributor

yesterday i sent to shop
skim my housing distributor
bcoz housing distributor wira 1.6 is bigger
can`t fit into head 4g91

many problem when i install
my engine so heavy when crank

if not mistake
can use distributor 4g91 Carburator
no need modified wiring
just plug n play
but the price so highest

Tomorrow i will try
distributor mazda B6+Coil (BOTOL)
we will see what going on..

i`m very2 excited to drive my car with new engine (SOHC to DOHC)
use 3 plate clutch EXEDY.

How the feel..:hmmmm:

 

[mr_lageenda]

now i already use original blok wira 1.6
i think i should change the title
bcoz my car now 4g92..

So tq for eveyone to try helping me
n give me the good idea..

so we will see the next from
the title is

4g92 SOHC To DOHC

who know the piston wira 1.6 diameter?Can convert into 4g93 or not?

yes... 4g92 and 4g93 share the same piston bore... 4g93 has higher displacement due to its stroke....
4g92 piston is slightly higher, means higher compression compare to 4g93 piston...
