Yeah, you'll get about 3 horsepower with the single cam.

i agree it is rediculous im suprised you can get anyone to join with sarcastic comments such as "yeah prob only 3 with a single cam" my bad i should have know that one extra exhuast valve would take me up 50hp, thats genius becuase im sure someone with a comment like that obviously has adustable camgears to take advantage of take split cam tuning capiblity. honesly i doubt it, im sure its a "stock" sr20det but wait what if he modded his stock swap, no way he wasted anytime or money on a rhd conversion, even if someone this great (who atempts to obtain the ability to demean people over the internet, so brave of him) found a 240sx that already had a sr and was rhd theres no way he would have been blinded by the jdm bandwagon. gosh only if someone like me knew what he was talking about, if only he was an ase master tech,if only he had experiance porting and polishing heads, if only he was just asking a simple question before he got to a dyno

they are my minions! i ordered them here via brainwashing and use of instilled fear.

nah, i kid...but really OP, dont expect it to be a hotrod. but i would guess at maybe 15-20 horsepower. due to ytou chucking the cat, upping compression and workin on the head, good gas/better tune.. find a cam that will work well with your application, that will help as well. get a upgraded clutch as well stock crappy clutch is not going to do and you will be wasting the few ponies youll have found.
all that being said, single cams can get the job done just as well as a dohc. more power to you man.

im pretty sure he rocks a single cam himself...as i always say, theres a little bit of truth in every smartass comment.
basically, hes going to do all this work, dump some dimes into it and hes not going to get that much of a result.

yeah man, if you do all that, itll be a fun car for sure but youll still be a ways off from a stock sr...its just how it is man, nasohc < boostdohc....
but i still encourage you to do your thing.
as far as the cam? no ive never know anyone who used that cam. shouldnt be a problem, just make sure the clearances are ok.

you may even call them and have them reccomand a cam for your application, tell them compression and what youve done to the head and they may be able to guide you in cam selection. just in case

Hahaha you mad?

Dude, I daily drive and drift a stock a** single cam. I f*** LOVE it, but they're not at ALL worth the money for an NA build. Boost or go home.

My 100% stock SOHC (minus emissions equipment removed) kept up with some rather healthy dual cams in it's day, but I would never dump money into it.

"what can i gain" is am illogical question to ask. Did you dyno pre-rebuild for baseline numbers?

If you were ASE certified (as I am, too) then you would understand that breather mods on an NA nissan 4cyl would yield MINIMAL results per dollar spent. NA mods are a HUGE waste of money, this isn't a chevy smallblock that just pisses power out with mods.

Trash me too if you want, I've had these cars for years, and work in the industry.

RHS's comment is factual to an extent. You will have such small gains on a sohc... they aren't powerhouses without FI

and i laughed SO hard when you thought RHS has a stock SR swap! your assumptions are sweet...

and O&J cams need solid lifters. think of that? have fun shimming those bastards every few months... on an NA motor...

these are the reasons noobs have a bad image. opening their mouths too quickly. there's a reason a few of us weathered it out on this forum, we KNOW what we are talking about...

RHS's SOHC sees a ton of tracktime drifting, completely bone stock, OE intake an all. (this week i pulled his emissions, it's first "mod" enginewise)

Actually, he was right on...he just misspelled it.

jargOn. Which means, anything meaningless or any talk or writing that one does not understand.

This is perfect, he has all these "meaningless" mods he plans to do to his NA single slammer. He will drop probably the same money as a t25 swap (done correctly, without cutting corners) and get like 75% less power from it.

More power to him! I have some respect, mostly out of pity for this man.

Damn well everything other than the header could be in preparation for a turbo build. I wondered the same thing before. I built my engine and wanted to know if there would be a gain with all the na mods i did. Did I care if there was? no because regardless im going turbo anyways. Little drift crew needs to stop getting their panties in a wad...
