TO start off I have a 95 240sx se. Engine has about 30k the body has more. So far I have this

Greddy headersInjen intakeASP crank pullysoch pistons (sitting in my garage, yield 11.1:1)

Now on to my future plans:I will need differnt cams so I was thinking one of the three

PDMJWTor 91-93 stock cams

I need and exhaust

hksapex'ior whatever one around 65mm

I want bigger injectors 370ccI would then buy an e-manageand a walbro fuel pump

and sometime in the future a port and polish job.

Thats what I want to do if anyone has any thoughts I would like to hear them. And what should I do about my cat? Leave it or pitch it for a pipe (dont take emissions into acount).

if you don't have to worry about emissions, get rid of the cat.

Even with the high compression and cams, and even fuel and timing tuning via the e-manage...you probably won't need bigger injectors if the car is to remain N/A.

270cc injectors can support ~190rwhp safely...and it'll be REAL hard to hit that with a streetable KA.

But the car will be fast, and fun to drive...you've got a decent start.

JWT cams are the best choice of the 3 listed, also the most $$$...

But I'd ditch the GReddy header in favor of the hotshot (or at least use a custom 2.5" "downpipe" to remove the primary cat)...

And build a short runner, right side intake that will sit where the battery used to be. It'll be nice for a little top end gain, a nice compliment to the cams...

Later - Brian

To tell you the truth I have decided to go turbo, I'll never get anywhere without forced induction or lotsa $$$$. So my new goal is 7 psi. 200+whp here I come!!!!

Or you can consider other people, instead of only yourself, and keep your cat.

good time to be had with 7psi ;)
