fuel pump for sure gone
+ air flow sensor or aps going (need to figure out which one still)
plus the nagging valve seals and recently discovered plug seals need to change
spent the entire day by the mech from 7 to 3
the car idling 100% better with the new pump + plugs
but right now i balancing brakes and gas when i stop
i jus taking stock check and weighing the options.
most important thing is i need my car working back to normal quickly
and with the least headache...and my headaching already

stay away from the GDI!!!!!!!!! though the concept is good and my galant ran quite economically (almost managed a 700km on a tank) it tends to be expensive when maintenance time rolls around........

~˜VëgŲ˜~, i estimate a conversion to be between $10k-15k
but i really interested in what engine gives me the least amount of fabrication and reliability

so there is no available option to go with another CS engine?

aye aye look what the vvl dragged in
look how one of the gdi fathers of 2nr crying it down now nah . . .
a while ago he was the #1 defender of the GDI Galants
Shift_GDI eh uncle
see what a 200 shot of JK does do yuh
idle, brother, we discussed on teh phone already, but to summarize:
4G15 SOHC with teh F1C1A tiptronic
recall:
this way u can reuse your tranny, no re-wiring needed and it will be bolt-for-bolt
or a complete 4G15 DOHC with the F4A41 tranny
for this we need confirmation that teh axels from the CS5A will work
secondary option is a trouble free one, thet was teh OEM mating in teh CK2's
mine doing 155,000+ km with only a couple oil seals and a distributor change + normal maintenance
4G92 SOHC with F4A41 kinda harder to find
may get a 4G18 in the bamboo though, need some looking around
call me, we will go hunting weekend

~˜VëgŲ˜~ dey na..

venum U sure the 4G15 EFI fits bolt for bolt in CS? If so that means all CK engines fit CS!
Line up a mivec

All talk aside...Did anyone ever put a CK engine in a CS?
then send name and contact
if this is the case, then Any CK engine would fit in a CS coz any CK engine fits bolt for bolt in a CK right?
i am gettin CK engines, i want to know what would it take to fit it.

the 4G15 DOHC from teh CK will fit, not direct bolt for bolt
mount mods will be needed
need to check that axels will work
teh 4g15 sohc from a CS2V will work bolt for bolt
Posted: April 9th, 2008, 1:51 pm

4g15 sohc from a CS2V
That there is what im looking for, but men only bringing in half cuts of GDIs
they tell me ppl GDIs that broke down coming in and buying another GDI engine
from the CS thread, so far it looks like
dev51 did a tranny conversion and
bobacue did a 1.8 gsr conversion from a GDI
i now reach page 15

jus dropped off the car to another mech to go thru everything again
guys the car driving so sweet eh...it pullin nice, no missin like before (new pump working!!) and new plugs in. jus i have to give gas and keep the idle up when i stop.
but i feel i have a vacuum leak, sprayed carb spray all over the manifold and intake. the idle went up when i sprayed by the back of the fuel pump and by the air line from the intake to the engine.
will keep post updated

RIGHT so here's the update
First Mech changed the fuel pump, tried to take off the throttle body from off the manifold and realize 2 of the 4 bolts spinning.
My manifold is plastic so once those bolts start spinning in the housing they wont crack.
So First Mech took off the manifold and changed the pump, started the car after, car not keeping the idle.
He came with a launch system and said the aps reading low, it can be the acc peddle with the APS sensor that needs changing.
Looked long and hard for a Singapore Cedia accelerator pedal found a Jap one but the serials didn match. That one retailed for $3000 was getting it for $2000
Oh btw the pump cost me $3500
Good thing is its directly from Singapore out of a barely used Cedia.
I actually saw 4 different fuel pumps all for 4G93 GDI each was different.
I believe the one i needed was a rare find.
Anyway, i didn buy the peddle
Instead i carried the car to second Mech he jacked in his Launch System and said all my sensors are good, no check light is coming on, something therefore is mechanically wrong with the car. the APS was readin good in his opinion.
He advised get a carb spray and spray everywhere that was interfered with while the car was on. He was convinced i had a vacuum leak somewhere. So, so said so done, i got a idle variation when i sprayed around the TB.
So i carried the car to him, he attempted to take off the Tb and found 3 of the 4 TB bolts spinning. So he took off the manifold, checked for cracks, and locked the bolts for the TB and sealed up the TB to Manifold area with some silicone. He sealed the Manifold and and mounted back up.
Tumble the car. Car working as if it never had a problem in the first place.
But i must say, the guy isnt a GDI man, he jus certified in auto mechanics and has years of experience. and good common sense!!!
So i good for the while, i MUST also say thanks to
venum,
SHO and
fras for all the help and advice. Good looking out guys
Fellas
venum hit meh with a suggestion eh, ah almost

if allyuh know what he say
It come like how Mr. GDI aka
Vega denounce GDI the other day
