here's a rough idea of how it should look like...
Google Image Result for http://www.himni-racing.com/images/Tial_44mm_inlet_outlet_clamps.jpg

I saw them in Enous before (1 utama). But it is closed for reno now. Maybe you can try the other Enous.

thnx....my friend just gave me his tial v-band clamp....and it fits well, a little tight to my liking though...

Hey guys,

Been trying to get the numbers these few days from Wiseco, etc etc...but can't seem to come up with solid data to arrive at a believable answer :(

Anyone here who modded their 4G93T terbalik have the data on the following?

stock engine block cylinder bore
stock piston stroke
bore diameter for 1.2, 1.3 and/or 1.5mm head gaskets?
combustion chamber volume (1834cc / 4 ?)
piston dome volume cc (for 4AGZE 82mm pistons, Wiseco 4G93T pistons with stock 9.0:1 CR)
piston deck clearance

Basically I need to find out what my CR will be with the following possible combis:

4AGZE pistons + 1.2 (or is it 1.3?) and 1.5mm head gaskets
Wiseco 9:1 pistons + the above gaskets

Thanks for any help in advance :D

4agze supercharge piston is 81mm stock, there are 2 type of ceramic coated piston, a zth member called wira tak laju selling rm700, brand new, 1 type is flat compression 8.9:1 and another 1 is low cp, 8.6:1 if not wrong.... the actual compression with the combination of gaskets above cant be say like that only, u better go do a compression test...

4G93 DOHC 16 Valve Turbocharged.
Total Displacement: 1834cc
Mitsubishi electronic with port fuel injection (MPFI)
Turbocharger: Mitsubishi IHI TD04L-13G-5
Compression Ratio: 8.5:1
Bore: 81.0mm
Stroke: 89.0mm
Maximum Power: 190HP At 6,000rpm
Maximum Torque: 250Nm At 3,750rpm

it is online, pls dun lazy to search bro, it is good to search those simple stuff and learn by urself so u can get more... lol

 

[nikolaiski]

of course the CR will b diff with e metal gasket rods and piston combis mah, which is why i want to ask who here who have alr modded their 4g93t knows the above things im asking..

for example what is the dome/dish vol of e 8.9:1 81 mm 4agze pistons vs e wiseco 9:1 CR pistons? i cant find any info on this, etc etc so i can calculate the CR of e engine BEFORE buying e (expensive) stuff..once fix alr then send for compression test a bit too late right?

and aiyoo...im not asking for our simple 4g93t data..that one of course i know la wa lao..dun say me until so bodoh leh..hahaha -tembak-

 

[peterj]

hurm, different engine have different data, for example,for same engine, some guys get higher oil pressure reading on their old engine compared to those with lower mileage..... u cant get exactly same reading for ur engine even if some people done same set up above, unless both of ur 2 guys engine just come out from mitsu factory... the most exact way and accurate 100% is do the set up and do those test... even compression higher, get thicker gasket, too low, get thinner gasket.. now the compression problem solved... but with 1 condition, dun change the gasket 1st cause will waste money, use ur stock gasket for measuring then start getting thicker or thinner as compared to ur stock gasket....

for the dome/dish volume, hurm, that u might can ask those with experience here to get the result , however, small error might also occur as i stated above.. same thing, best way is to get the block and measure it with the piston reach the top dead center... wan more info, go online or book store search some stuff on thermodynamics regarding to thermofluids or heat engines....

and some of the data answer ur question

stock engine block cylinder bore == Bore: 81.0mm
stock piston stroke == Stroke: 89.0mm

yaa man..my decision to build up the 4g93t terbalik frm scratch def v confusing..tomo going to have to go library and read some more..nvm wait i fed up i chuck to my foreman..hehe..thanks bro

Bro bore & stroke goes side by side, what u wanna achieve with ur engine is the ultimate goal. Low to mid power, or mid to high power ? If it's a drag racing engine then by all means mod it kaw kaw but dun think it's possible to be a decent daily driver anymore.

 

[nikolaiski]

no la bro..im not into drag. i want a consistent spread of power from 2500-7000rpm IF possible..flat torque curve (i know 1.8 la so need some top end sacrifice)

car will b driven daily and tracked at PG and sepang for the next 5 years without the need for major work..so my idea is to really tear the cm5a block and gb down, rebuild it (maybe with a mivec head) and running a conservative tune of 250-280whp on 95RON with a standalone that can fine tune the fuelling, with the SMALLEST possible turbo as i want the torque to come in early. any suggestions? thinking of using the stock engine specs such as CR for good response low end, and CC and blueprinting/forging it for reliability..and in case gatal..lol

hello guys I'm planning to do 4G93T with Mivec head 4G92 DOHC. I will be using Wiseco Turbo Pistons 81.50MM 0.5MM oversized, Duratech Conrods, ACL Race bearings and turbo not decided as yet. What parts will be replaced in this conversion any idea ? I will be using 4G92 DOHC Mivec Head, 4G92 Mivec wiring, sensors and ecu. 4G93 Block, pistons, conrods, bearings and head gaskit of 4G93T most probably 2.0MM. What else will I be needing ? I have a confusion in my mind which water should I use ? 4G93 or 4G92 DOHC pump ?

This is the terbalik version aka CM5A and CK series ? Or the older CD5A series ? I think u need computer management since ur mixing mivec and 4g93T tech, u could try askin a few sifu who manage to mix n match successfully, as far as i know if u use mivec ecu, how can it control the fuel ? Turbo need very good fuel control le too lean or too rich and u will have problems later. Most of the problems come if ur too lean tho, rich usually is ok.

Just wan to reconfirm, anyone encounter abit of engine whine ? Not the tepet sound it's abit like grinding sound. I change everything like bearing, belt, only cam gear didn't change. When idling can hear like grek grek grek den nothing den grek grek grek den nothing. I try to get the sound later once the car is in my hands now tidying up the interior and finishin sum touch up.

Anyone can share what item u guys use to stick into the ori bypass valve hole ? I found those rubber stopper from plumbing shop but my mech say it's too soft, scare it might not stand the heat and melt or get sucked into the turbo.

Thank you sir for your kind reply. I am using CK4A as it is a Mitsubishi Lancer 2006 Model. I will be going for a standalone ecu for tuning[Fueling, Timing..etc]. But I need a good standalone ecu which has every function anti-lag, stepper motor, launch limiter, mivec controller etc. My aim is for drag no streeting. I have a GT30R lying with me but need to change its housing as it is too big any suggestions for housing ? One thing more can I start my car and run perfectly with stock ecu. The engine came up with Automatic transmission and I am gonna swap manual gear box. Is it just plug in manual gear box or do I need to play with wiring ? In mitsubishi do they have the same ecu for auto and manual transmission ?

Stand alone will be better for your case, bout the turbo maybe u can try hybrid with evo 4 - 6.5 ? If the GT30R is a brandnew turbo then maybe u can try to customise manifold for it ? If u wanna change gearbox i believe it's pnp but depends on which gearbox u r using ? And ur speedometer might need to change if u want it to look neat I have seen people usin auto speedo with manual just ignore the 1,2,3,4,n,p thingy. Btw depends if ur goin for 4WD or 2WD ? Since u mention drag I suppose it will be a 4wd setup ? CK4A is mivec right ? It should be the engine ? 2006 u should be using CS body lancer i think ?
From the way u mention I think ur not from Malaysia ?

hi wanna know 4g93 gsr n 4g93 gdi turbo manifold the same?

 

[Solty8]

hi wanna know 4g93 gsr n 4g93 gdi turbo manifold the same?

I never compare side by side b4, but I assume it's diff coz one is from the E4-6.5 generation another is from E7-E9 gen ?

Maybe u can try source E7 parts ? I will try to dig more info bout the parts for gdi.

 

[nikolaiski]

a 4G93 GSR manifold will NOT fit a 4G93GDI without modding tge location of the turbo, etc..I assume this is e CS5A

forgot to add..if u want the downpipe frm an airtrek turbo will fit

I assume it's the CM5A 4G93 GSR ? or is it the CD5A ? CD the timing belt is on right, CM and CS both the timing belt is on left.

 

[nikolaiski]

yup since gdi only have terbalik punya version..i know the gdi and gsr manifolds cannot swap because the cs5a tf035 and cm5a td04l tapak isnt the same, so u have to swap one shot if u want with the lancer cs5a

hey guys.. does the auto gearbox for 4g93t last long? because i m thinking to get an used car with 4g93t auto...

thx for ur answer =p

The ori 1.5 DOHC Triptonic I got gearbox problem b4, this is due to oil change not done properly, other friends with 4G93T triptonic never have major prob, most problem occur from bad oil or boost too much till gearbox can't withstand the power else everything is good without problem.
U can always change to manual later if u find that the triptonic gearbox is not ur cuppa tea. :proud:
