the unthinkable!!

[Ricer240sx]

hey guys whats up....i am thinkinga bout building an NA 240, but i want to do it with a motor that will have some "zip" to it. the 2.4 is to big of a 4cyl to rev how i would like with out alot of work and money!! lol so i was thinking about getting a n/a SR and throwing it into my 240 (if i dont trade for an AE)

i was wondering, what parts are compatable between the NA SR20s that came in the Sentras/200sx's and the RWD SR???? because it will probably be really hard to find performance parts unless there are a lot of interchangeable parts between the two because i have never heard of someone running an NA SR in there 240 in the states.........

and if there is someone out there that has done this dont be afraid to chim in with hints/tips/secrets/whatever!!!

Was it SCC that did a Sentra Se-R N/A buildup? If so you may want to check out what they did.

get a s15 na engine . 200hp, if i'm not mistaken it is called vr20

[9240sx]

The S15 Spec S the N/A version comes with a SR20DE with VVT.HP-165@6400rpm

[AJ1356]

that is what i was under the impression of, but then somewhere on this forum i read something about the spec s and a vr20de.. and that is where my confusion started. do you know what is up with that ??

all that money ur gonna spend on a N/A s15 engine is just not worth it to go N/A

The S15 Autech version has a 200hp SR20DE with hi compression 11.7:1 pistons.

Concidering the weight and power benifits its actually a pretty good deal. Over 100 lbs or more off the front of the car and an extra 10-55hp never hurts (unless its a s13 sr20de). People pay $500 to save 12 lbs with a carbon fiber hood, thats about $42 a pound. So concidering you get around $4200 worth of weight savings, a more balanced chassie and some extra ponies, that S14/S15 NA SR starts to look like a good deal. Obviously not optimum for a drag car, but a curb weight of under 2300 lbs would be fairly easy to obtain (lighter and more powerful than any mazda miata), it would eat other cars in the corners.

Build yourself an SR20VE. It can be converted to RWD, and you could setup ITBs if you got a standalone. Do the cams and a great job tuning and you could be 200-230whp.

You use the VE head on a RWD DE engine, and there aren't any cams currently available for the VE engines other than the N1 cams which would be around 205whp all together WITH high compression pistons.

Get a SR16VE head and build a N/a monster with an AEM EMS, DET Coilpack Ignition, ITBs, and around 12:1 compression.
