inline 6 convert to inline 4

[PuristOfRacing]

just wondering, a car that came stock standard inline 6 converted to a powerful inline 4 (lets say cefiro A31 convert RB20 to SR20), will the handling be significantly improved? i heard that some SuperGT cars does this.

Isn't Inline 6 more powerful then Inline 4 ??

For weight.

Some JGTC cars do away their 6 for a 4 banger.

 

[gti88]

actually its more to better weight distribution.

g88, not necessary 6cyls are more powerful than 4.

if u mod kau kau SR20det and superlight weight the car then ok ler..

Could a 6 cycl 2.0 be lesser powerful than a 2.0 4 cycl? A stock SR20 would not be faster than a stock RB20. Engine to engine. But car to car is another story. And tuning wise. But a 4 cycl engine would not be better than 4 cycl. Unless you are searching for weight savings.

 

[PuristOfRacing]

its about number of cylinder, but how well design the engine is.

 

[BLaCkHoWLiNG]

do consider the amount of torque generated as well...

yah... 6 cycl block are more stronger den 4 cycl.. juz like RB26 compare to 4G63.. juz my 2cent..hehe

block thickness/strength are not dependent on the amount of cylinders.

btw, wont you miss the smothness of a 6cylinder?

i guess it is best to have a 6 cylinder with larger displacement to run at its optimum levels.

No need to replace or convert inline 6 to 4 cyl inline..

Just try to modify that stock inline 6 and the suspension to match the engine power, so that the car have a better handling.

Just asking... what is the if we are comparing to engines.. might as well compare to engines with the same displacement.. there fore RB20 and SR20... which has a longer stroke??... the one with a longer stroke should give better torque right?? though if the engine is short stroke you will be able to rev it dem high..

Another thing is I know 6 in-line doesn't need a balancing shaft as it does not suffer end to end vibration unlike the 4 in-line.. but the weight factor here wouldn't it be the key point?? the space use in the engine bay too... just my opinion..

 

[keisuke takahashi]

IMO those engine with low RPM have a longer stroke.

I'm not sure the RPM limit of those 2 engines

Correct me if I'm wrong


Thanks :regular_smile:

well i did say compare sr20 with rb20. rb26 vs 4g63 would not be an even match.
