[2slow2steady]

Dark sin....

RoCk OoooOOO!!!!

that is the fastest mivec ive ever seen on street drag.very impressive...but lost to my frens 2litre vtec.
a fully blown 2litre vtec only win by a bumper...

Wow 2 litre piston, how do you do that:regular_smile:

actually, its not really 2.0 l .. its about 1.95L.. i round it up to say 2.0... but you need to change out the con-rod .. our 4g93 con-rod = the weak-link.

Guys,
just want to know what's the best exhaust system for 4g93 na?

tq.

 

[Yong_5290]

theres no best xhaust system for 4g93 lah...depends on ur budget..
u can go for R3 complete xhaust system also...which is tuned for 4g93 itself..
then theres complete hot bits system
and many other

So what you are try to say is, It is possible to bore the 4G93 block from standard 81mm to 85mm in order to accommodate a Perdana SEI pistons in!

As you've mentioned that you saw a gti with this mod,did you actually saw this pistons in the block or just heard about it?Is the car still on the road?

Well I would definately would like to see it as it is a very intresting.Don't worry not intrested to copy but you know just curious.(kepo chie)

Hu hu huu:regular_smile: well said. Instead of using 85mm pistons,,,better take 90mm piston, much more better. Since Gti block are soo flexible, they can expand like rubber or it might be made by rubber, so elastic one.:shades_smile:

Advance and retard is the firing timing for ignition.Advance would be firing before TDC and retard would be firing after TDC.
This is best to be done by a mechanic who knows what he is doing in the first place.Reason being when it is advanced the initial power would be very responsive but there would be side effect.Pinking would be produced during high speed due to limited/pre ignition fuel.When the distributor is retarded knocking would be produced due to post ignition.
How skilful is the mechanic can be evaluated after this adjustment.
Advantages of this precisely adjustment is good fuel consumption,smoothness and early morning you start the engine you should be able to see vapours coming through your exhaust!

If the above mentioned statement by anyway is not correct please excuse me and don't taroh me lah!Don't mean to condem anybody.

This is quite intresting whereby they are playing with strokes.Yes please tell us roughy how do you lenghten the stroke isit by using shorter or to be precise use 4G63 rods which is 85x88?(4G93=81x89).As they have mentioned earlier about Perdana SEI.

My Q is again can this be done????????

Earlier our friend mentioned the piston 85mm now another friend is talking about stroke........
Later what else?????????

Reliability friends think of reliability how reliable we can build an engine which is powerful not just powerful and not reliable!!

It is a different story if we are very rich spoilt brats who do not know how to appreciate the value of money!This is what they will do by putting holes on the walls of blocks and not the piston to see how fast the engine can go for a short 400m sprint and mind it only one sprint!!!!!!!!!!!

Wei lau ya luit bukan senang mau cali o kawan.......

No offence to any one.

 

[Yong_5290]

i remeber i read in sumwhere the max is 4g93 wit 83mm piston
