Was just wondering what is the best and most effective way to get more power out of a k motor?

eg. supercharger, turbo, efi or anything else that anyone knows of.

I'll hopefully be running into some money soon so i wanted to do up my engine without doing a full blooded conversion.

so whats the ultimate upgrade?

twin charging, supercharged and turbocharged

 

all forged internals, completly balances and blueprinted

 

and some amazing drivetrain bits

 

and then you'l be laughing.........at yourself because you could get the same power out of a dirty nissan motor for alot less money

 

nah jk,

 

depending on how much money you want to spend thers a fews things you can do,

3k head on a 4k will give you abit of extra power, as will getting your cam reground geting and exhaust and wber or modifying the snadard carby,

 

everything depends on your budget and what you can do yourself

well i'm hopin to get a worked 4k with a webber. but was wonderin what else i could do to it that would be the most effective

3k big port head on the 4k block it gives a big difference considering how cheap it is man

check this out!

1. choose 2 out of: speed, reliabilty, cost

 

2. more power from stock = more undriveable (useable powerband)

 

3. heres my version of a k series engine power list from least to most:

 

3k std

4k std

5k std

7k std

 

warm na

hot na

race na

 

supercharged std internals

turbo std internals

 

supercharged aftermarket forged internals, efi, ecu, intercooled, boosted etc

turbo aftermarket forged internals, efi, ecu, intercooled, boosted etc

 

driveline and gearbox may need upgrading at hot na onwards.

might add power estimates later...

uve done a 7K swap or you just saying that?

NOS it.

NOS it.

 

lol that'd be pimp

one of my mates had a ke70 with hot as NA 4k that put down 56rwkws, 4age should do this standerd :jamie:

 

a speedway mate said he made 3k run 69 rwkws at about 9000 rpm

Should?

 

They normally make almost 20kw more at the wheels.

You lose more in the drivetrain in a RWD car remember....plus a lot of 4AGEs are getting rooted these days, especially bigports. I've seen a bunch of AE82 TCs pull between 50 and 60kw at the front wheels all on the same dyno, on the same day.
