4G94 Mivec

[kairigi]

4G94 is SOHC right? Doing a 4G92 Mivec hybrid, compression ratio have to take in consideration.. plus i dont think the engine can rev till 8K RPM+, since the engine internals are bigger.. and power wise, 200HP is possible with the right tuner and the right items..

alright thank you for your precious opinion !

but i will push all teh way to the limit for this convertion

sorry forget to mention i'm doing this to terbalik engine. CK4 for Waja

Mind telling your halfcut is from CK4A (Lancer 4 doors -wheelbase like evo4-Evo6) or CJ4A (Lancer 2 doors or hatchback like Putra). Manual or auto?

For manual tranny, both ratio are different for CJ4A & CK4A, in which CJ4A more superior (from my experience)

Ratio vs speed for CJ4A would be as follows:

Gear 1 = 62kmh, redlined 83++ rpm
Gear 2 = 102kmh, redlined 83++ rpm
Gear 3 = 160kmh, redlined 83++ rpm
Gear 4 = 195kmh (sometimes 200kmh-depends on load - RSM readings), redlined 83++ rpm
Gear 5 = 237kmh flat. Seems power cut there at 7200rpm. Top end power quite strong. torque still available.

Much better than my Euro R H22A-R last time.

It's also much better than stock Mivec CA4A. 5%-10% better than Mivec CA4A 1.8 (forget what modded inside but definitely not highly modded)

Get a sets of wild cams would assist at low-end & mid-range power as top-end power not too much to worry.

ECU hard to reflash. Even Charlie Matspeed cannot do it (that was few years back. Now not sure).
Customised cams maybe Charlie able to do it for you.

That was the findings and conclusion from me after driving it from 2000-2005.

u can buy the lighter flywheel somewhere in Sunway. Other parts is you really keen on modding, need to goggle since it's already old model now.

My CJ4A non-mivec auto gearbox is a good ratio for turbos, though the stock SOHC 4G93 redlines at a sad 6500RPM..

1st - 60kmh
2nd - 108kmh
3rd - 160kmh
4 - 200++ kmh because my engine not strong enough :D

I'm not sure which model it come from , due to last time budget was tight i just get a engine kosong .

Many thing are rojak inside my car .

Thank you for your advice . will google for more performance parts!

Later your gearbox sure cannot tahan !

Hi I think you should scrap the 4g94 mivec and go with a the 4g69 mivec from the rallyart, outklander or eclipse i"m not sure how easy is to find that engine in your contry but alot of the guys from P.R are scraping there 4g93 & 4g94 proyects and going with the 4g69. the 4g69engine from stock produce 162hp and requiers very little modification to make it work in the lancers here is a pic of the engine in a cj lancer

here is a link to another cj with the 4g69 swap & stock

good luck !!!!!!!!!1

Bro ! thank you for your good information provide by you! but at here very hard to get those engine! anyway i will note about this and will post up here when the project start at my hometown to show you guys here !!

Merry Christmas to all forumer here! have a joyful night !~

we have play with 4G94 mivec.. there's 2 type of hybriding 4G94 mivec.

1st - using whole 4G94 engine bawah + mivec head
2nd - using 4G93 block & conrod with 4G94 crankshaft.

yes, i wont rev like 4G92 mivec (9000-9800rpm) but with a great set-up, u still can achieve 8500++rpm with 4G94 crankshaft. u may lost 1000rpm, but u gain 200cc. with proper gear ratio (due to different torque curve), u surely will smoke 4G93 mivec.

it's a nice project to try. what u need to remember is, longer stroke + short 4G93 conrod = higher load at cylinder wall. imagine how the position of conrod while your crankshaft at 270degree. this is the most critical point. we have made the rod became 'S', and the cylinder wall broken before this project success. hehehee... another thing is, u need to play with the compression correctly. since the stroke now a lot longer, the compression will become a lot higher. maybe the hi-cam with longer overlap duration will help to release some dynamic compression pressure to prevent knocking. depend on your set-up. R&D is most important here.

Thank you for your time to reply here .

So base on the option above which hybrid are you think is the best to choose from ? and performance wise ? big different .
so the two option above what hp does roughly do you think can reach ?

for me, the best is using 4G93 block & conrod with 4G94 crackshaft. the problem with using 4G94 block is, it's tall n u need to use the 4G94 conrod too and this conrod is quite thin. not suitable with highrev + high compression. the only advantage with this setup is it will generate less load on cylinder wall. i used to know one mivec with 4G93 block + 4G94 crankshaft, stock mivec ECU (rechipped) + VAFC, stock mivec intake achieve 220bhp on wheel with very hi torque (dyno dynamic) .

ok you prefer option 2 . wow 220bhp on wheel is a great hp man this is awesome! the information you provide are really useful for me! if in future i've any problem i will pm you about it .

Cheers and Merry Christmas!!

 

[joe_mirage]

my workshop use 4g94 block + mivec head setup. produce around 208whp with stock bore size and high compression cp piston, polished cylinder head, 70mm s90 tb, stock mivec intake and haltech p1000 standalone ecu. picture below.

last time clocked 13.2 sec ( sepang drag battle now use new timer, more accurate ). first runner up in 2WD open category. OTR body. now they are progressing to modify the engine to give better power. hopefully pass 210 whp mark.

Bro i see this picture before , are your workshop name MAG ? there are very good mivec sifu ? at east malaysia not much good mivec sifu!

by the way your ride is very clean! but i'm terbalik mivec do you think the hp produce will also reach 200? woww how much you spend on this ? feel so great to see so many mivec sifu reply my thread

Thank you all ! if i've any problem i will pm all of you !

 

[joe_mirage]

thx for the compliments. saw it in my blog is it :P in reality my car is not that clean :P

btw, yes. i did my engine at MAG. i can say that they are very good with mivec because most of their race car got top place since the old time and even until now. they are also very humble and willing to share knowledges with their customers. i'm also newbie with mivec actually.

your mivec terbalik also got a lot of potential. i bet can reach 200whp mark. but you have to sacrifice a lot of money and time. btw, i'm very happy with my mivec. eventhough the engine only got 160whp (dyno dynamics) at this time.. i think it is more than enough for a daily driven car. hehe.

regards.

great.. look like mivec head + 4G94 block set-up also can be done nowadays... care to share what conrod u r using??

It's MAG at Sek26 Shah Alam?
If yes, heard stories about good and no good about the workshop previously.
Been there for a visit, got few my friends who send their cars there for mods etc.
BTW it's a nice and clean workshop.

yups. can be done. but anyway the pix that i posted is not my engine. it is my mechanic engine. if i'm not mistaken, he's using k1 technologies forged conrod.

nope. it is not located at shah alam. the one in shah alam is now known as MH Tuner. MAG Apprentice is now located at senawang, seremban :).. yeah. very nice and clean workshop :)

Joe ! yes i heard MAG before but too bad we are at east malaysia so parts and skill are way near to west malaysia! But if i've any problem i will come forum to ask or pm you guys if ! very happy to see there are so many mivec around! your 4G94 using mivec head , beside that any other parts need to buy aftermarket or most of parts can use back ? can you give me more information if you don't mind btw what is your blog address ? hehe

 

[kairigi]

Well bro,

Its a sad fact that MIVEC engines don't get many hardcore aftermarket option, but yeah, I'm also feeling a bit gatal to buy the CJ4A ZR that's lying around my area.. to go turbo or to go MIVEC is a hard decision.. but taking the mivec will be an easy option since I have my current 4G93 engine so I can mix them together :) as for the gearbox.. I pray my auto tranny will last

 

[qme9019]

very sad to hear that . well we all know mivec are not famous like VTEC and of course after market parts are not that much that's why not much option to play . But really salute to mivec owner there ! just don't know why when i know this is true but i'm loving my mivec more and more , i feel it was a hard and need lot of cash project but when the result is awesome i am happy !
