Engine Swap, decisions decisions.......

SAE hp and lb-ft are not really metric. The last "power" one I have no clue what that is. Probably SAE hp (~746 watts) or maybe JIS hp / PS (750 W) or perhaps kW (1000 W).

I was refering to the last 1 of that post, its power is scaled in kW and torque in Nm...BTW isnt PS about the same as SAE HP?

Yep PS is about the same as a SAE hp, as I said (one is 750 watts the other is 746 - the only reason it exists is that Euro carmakers saw it easier to make the calculations from kW, just multiply kW by 3/4 and boom PS for your advertisements)

The exact conversion from Nm to lb-ft I don't recall, but a Newton is about 1/5 pound and a metre is about 3 1/5 feet, so, well hell I'll look it up...

1 lb-ft = 1.3558179 N·m

I dunno why everyone still uses hp, kW is nice and simple and you know what it is, wheras there are a thousand different definitions of "one horsepower". I guess it sounds good for the ad copy to say "300 horsepower" because it makes people imagine the car being pulled by 300 horses... in reality a horse can probably put out 10-15 hp for a few moments, then drop down to something around 3/4 hp or die/fall asleep/etc.

then for the time being lets say 1SAE HP = 750w
so thus 1HP = .75kW
so wouldnt you divide 'x' kW by 3/4 to get HP?

but I agree if EVERYBODY used metrics the world would be a better place

like 1 ft = 12 in and 1mi = 5280ft
while 1 m = 100cm and 1 kM = 1000m

much easier to conver without doing stuff like
1mi = 1.6km or 1in = 2.54cm and sh** like that

Yeah you are right. It's like trying to tell someone how to spell a word, it's easy as pie to write it out yourself but to say "a, d, b,..." it's much more difficult.

I hear ya on that one it hapens to me all the time

[Arashi666]

all thats going on I might just go with F22 Turbo later on thanks for all the input though

[holein1]

I'm really having a hard time deciding what engine to swap into my car the choices:

STOCK) F22B1: 2.2l 16v I4 SOHC VTEC 145hp, 147 lb-ft

1) H22A-S (JDM): 2.2l 16v I4 DOHC VTEC 220HP, 160lb-ft

or

2) J30A1: 3.0l 24v 60° V6 SOHC VTEC 200Hp, 195lb-ft

Pros and cons

H22 is easier to tune and is a bit lighter than the J30 and I can keep my intake, con is that I need a new ECU and harness (LOTS of work) and cant find one with an Auto tranny

J30 much more torque is a definate plusand decently better milage than the H22 (J30 came in the V6 version of my car)

any input would be cool at this point
