SR or RB?

Hey guys, looking to buy a s14 and I would appreciate if you help me with a decision. A couple questions I have are; Which one is more reliable, and more efficient? Also, which one is cheaper? Which can withstand high hp? and last but not least how much would each swap cost me if I were to do it? Thanks Guys

Just trying to give you a heads up bud.

NicoClub and 240SXFOURMS are for spoon feeding.

Ask around there first before you do it here. Plus do some searching on google. People can be dicks around here.

Just trying to handle the situation before somebody else(who isn't as nice) does.

Both are a waste of money imo but since you asked:

RB CONS:

Heavy as fuck.

Oil pump drive gear breakage.

Oil in head likes to stay there. Go ahead and throw it hard or corner hard enough to slosh a low oil level in the pan away from the pickup and the potential to spin rod bearings is pretty high.


RB PROS:


Sounds good as fuck.

Godzilla swag.

Torque.

Strong valvetrain

Doesn't need very much "building" to be fun.



SR CONS:

Weaksauce soda can block.

Shitty valvetrain/rocker issues. Keep spares handy......

SR PROS:


Light.

Lots of parts stateside due to Jdm hype, drifting demand and people hating ka's. Blow it up, parts are just a craigs add phonecall away and they pop up pretty frequent in the zilvia f/s and other 240 forums.....


If i had to pick, i'd dump money into an RB. Just put the oil plugs in the head, install a drain to the sump and rock a crank collar with an n1 pump maybe. But my inline six of choice is of the jz family. KA is my favorite 4 banger. With the right tune, you can have a reliable 300+whp internally stock down to the headgasket. Detonation, overheating and poor maintenance cause head gasket failure. Eh, it's whatever. Just do your homework and dont worry too much about what you'd like other people to think. Fuck em, it's your car.
