The best way to upgrade a 4g93 na....

[qamarul]

I want to know how i can upgrade my 4G93 na... and how much it's cost...anybody can help me....

 

[93na]

standard mod is air filter, exz, bigger t/b intake cam pulley, better spark plug and much more

hardcore mod= high lift cams, max p&p head, high com piston, standalone ecu and much more

there lots of topic on how to mod 4g93 na engine try searching it first....

good luck...

go for suspension 1st..its worth

 

[joe_mirage]

start with I/H/E modification :)

i think i want to put gti cams and 1.6 piston... is it ok... which type of piston i can use...

 

[xtremeleo]

just use a thinner gasket, simpler

xtremeleo, you are also here. I have a SGTI for track. My problem is the blooming Siemens VDO. I cant tune it without using a Piggy back or Changing all the wiring plus ECU to MMC.
I am also waiting to do a rebuild as engine in SGTI is 160,000 KMS. Only suspension and chassis improvements were put in. Plus off course final drive from Mivec, CUSCO LSD and roll cage.
But my main problem is I cant tune the Siemens.

My workshop quoted wt porting of head plus 1.6 pistons, rebuild. - RM2K

i heard siemen ecu can be tamed by using a perfect power smt6, or the works emu (iam not sure of the name ler..), tune dat on a loaded dyno and u'll be good to go. i wudnt go for a shorter fd if iam upgrading the power sir, the gears will feel too short nanti.

sounds reasonable enough for me, iam not fond of porting, seen too many costly mistakes on frens' cars

You can see another SGTI in the HPC Endurance race, its a Titan sponsored one. MY SGTI share the same workshop RS. RS is pretty reliable. But again, its a Piggy Back. And Piggy Back cost money. I will most probably find a 2nd hand Unichip and get Robyn to tune it.
But I am getting slightly excited on my B4110 project.

Between pnp and high camshaft, which should be done first? Have anyone tried the newly introduced JASMA camshaft? is it reliable with good power increment in overall rpm range? any review on this product installed on 4g93 dohc with dyno chart?

intake, header, exhaust

I have 4G93 SOHC in my country. I'm upgrading the head to 4G92 Mivec with mivec ecu, wiring and sensors. Going for turbo wiseco pistons, duratech rods, acl race bearings and GT30R turbine. I need to ask that for conversion of head which parts I have to replace ?

between the two, i wud get the high duration/lift camshaft sir, iam not fond of porting it down without proper equipments, seen too many mistakes being done for pnp process. the most dat i wud suggest, is polish the intake runners, no comment on jasma cams. i suggest u stay clear before hearinng sumthing good about it sir

 

[Shinjite]

For PNP, I would recommend it done by professionals and max it out 1 shot so next time no need to hassle to redo again. But if you fear on screwing up, cams is the best bet to go first because you can just swap back to stock cam when needed.

if worry do those plug and play item first lor...

i had this problem as well as i was trying to do a BOT for a 4g15 svdo. on contrary to the majority, svdo outperforms mmc in terms of fuel and engine efficiency. Power sports tuning equipment can be used alongside with svdo whilst maintaining the ecu's operation and simultaneously accommodating other mods on the car.
