need some help for 4g92 twincam upgrade.....

[Yong_5290]

if u put metal gasket 1st b4 turbo...u r lowering the compression ratio...which will result to sluggish feel

 

[alan_ee90]

haha, bcs he juz tell me need performance

 

[AD_EG]

ok ok thanks.....
but now i think i will just overhaul and PNP and then over size metal gasket ....
are this 2 stuff correct ?? and BOT on later on XD wa ka ka ka

if can better do simultaneously...do the overhaul +gasket+ BOT together..save on labour

and like Yong said,if you change gasket 1st then you will suffer...until you complete the BOT

 

[coolman91]

oh ok ..... so i overhaul and PNP 1st can i ?? or still got stuff that i can do before bot on...
because my BOT on will BOT on after 1 year like this so quite long .... that y i just overhaul and play long time 1st.... so in the overhaul time still got what i change that can add hp de ??
sorry ya.... my plan is BOT on later with HIGH BOOST around 1.5bar .... that y i am saving 1 SHOT do 1.5bar.... any idea .... and can my block stand 1.5bar ??

 

[artworkz]

1.5 bar block can, but con rod maybe cant run 1.5 bar in all time. y dun jz use normal gasket before bot. wen wan bot, u jz change to GSR piston. change piston no need to open head, jz open oil sump. plus u need minor mod on oil sump wen bot. i dun think u can drive as normal wen car run without turbo with low compression.
bro yong hv bot experince. ask him advise.

 

[alan_ee90]

excuse me, can i know wat is bot?? and then as i know for metal gasket for turbo, actually got thinner right? can make the compression higier...is it??

 

[zac]

BOT is bolt on turbo...

thinner gasket make higher compression thus engine response better, however the cr must be controlled otherwise you will spoil the engine...

 

[Yong_5290]

i never bot b4...dun have the chance...but also ask around n do many research about bot..
yes...got thinner gasket also for those NA kaki who wan higher compression...but ignition timing have 2 jaga a bit..

doing 1 shot save a lot on labour...like when i transplant engine...i quickly replace the cam,clutch and xtractor....save me a few hundred buck...

 

[coolman91]

i know.... but i cant do it 1 shot.... haiz.... i think my turbo project also need buy step by step then only go work shop install and so on.... that y my project need 1year... T.T

 

[alan_ee90]

ya 1 shot save a lot labour charge

 

[coolman91]

dont want la.... 1 shot i still need long long time leh.....
maybe 1 year maybe 2 year that time my car dont know black oil leak until how !.....

 

[alan_ee90]

then u slow slow enjoy the power lo, like that also good.... bcs if u 1 shot feel the full power, then fast boring, slow slow feel then u will feel syok

 

[coolman91]

ya ya this is my plan also..... in the between overhaul can do wat for MAXIMUM NA ??

 

[alan_ee90]

hmmm, juz for easy la, juz make the piston size bigger and change the connecting rod to lighthen, and change lighthen flywheel....cam and cam pulley

 

[coolman91]

i heard some friends ask me do this ...
change throttle body and intake manifold to perdana is this suit me ??
will this help me a lot ??

 

[zac]

if you plan to BOT then dun waste your budget on this kind of mod... BOT itself will bring enough power, even if you wanna upgrade after BOT you should go for aftermarket item which perform better than stock perdana item...

 

[coolman91]

after i have change to BOT on the TB and IM also can be use back the perdana wat ??
need change again meh ??

if your budget 2k..better get japan adjustable...with hi low / soft hard.

at least can set for comfort and when you wanna play can put stiffer.
