Runnin13s

i was wondering what would be the best swap to do and how much time and money it would cost

mpg9999

SR20DET, and look a few threads down for a bunch of info.

runnin13s doesnt have a 240 lol

Then why is the title "what kind of swap can i put in my 240"?

gopedracer (jeremy ) dumbass i just got one that why im wonderin cuz i sold my hatch for it dont u feel smart

for the price of an SR swap (front clip + install + FMIC) you can build your KA to handle whatever you want to throw at it and boost the shit out of it. or if youre short on money you could build it and run a dual stage 250 shot nitrous system and be putting down around 400whp. why swap?

....."the KA24 has structural problems with the block and piston speed issues so ultimately the SR20 will produce more power. The KA has harmonic issues much past 7k rpm which can result in catastrophic bottom end failure, like the main caps seperating from the block! The SR20's finger follower valve train also allows higher valve velocities and more area under the lift curve. The SR's ports also flow better. The SR has lower piston speeds and will rev higher with less mechanical stress.

For racing the SR is much better suited but its hard to compare both here as the 240 is a much better chassis. RWD mutilink and good geometry strut front suspension is going to kick the Sentra's econobox strut chassis's ass. In a drag race the 240 will always hook up better all other things being equal. The SE-R is hampered by a butter like transmission that shreads third gear easily.

It is difficult but not imposible to get a turbo KA much over 400 hp but it is super easy to get 400+ hp out of an SR20. The most powerful turbo KA's I know get in the mid 400 hp range while the most powerful SR I have worked on made 540 hp in streetable configuration and later 650 hp...." -Mike kojima

if it was my money id build and boost the KA.

rough estimate of ka24det setup:
spare ka24de - $500
worked block, balanced rotating assembly, forged internals, high volume oil pump - $1600
tubular turbo manifold, 3" downpipe, 3" IC piping - $1500
valve job, p&p, turbo grind cams, upgraded valvetrain components - $1500
generic turbo - $1000
FMIC - $800
sell off your old KA - neg. $500

= $6400

rough estimate ka24de N20 setup:
spare ka24de - $500
worked block, balanced rotating assembly, forged internals, high volume oil pump - $1600
valve job, p&p, N20 specific grind cams, upgraded valvetrain components - $1500
NX Dual Stage N20 system - $1500
sell off old ka - neg. $500

= $4600

Price I've been quoted for blacktop SR20DET into S13 (drop off / pick up):

around $4,000-$5,000.
add tuning, upgraded manifold, FMIC, 3" downpipe, cams... around $2700

so that takes your price of the SR to about $7,000 - $8,000 for an unbuilt motor. also you can find KAs all over the place. youre gonna have to wait a while to have your SR show up on your doorstep with a banged up oil pan because it was sent in seram wrap from malaysia ( ) i dunno to me it just makes more sense to build and boost the KA but look at greaser hes running 10s on an SR...
