Redtop or Blacktop

[solid]

2 engines, one old, one new, does the age really make a difference?

[slw240sx]

only if its jailbait

[I H8 UR DSM]

so true

[danielsca]

Well the Red top is closer to the S14 engine so the 20 or so horses may come in to kick the crap out of so nasty V8. But don't get me wrong they are both great egines. Happy Hunting

did that comment make sens to anyone I was under the impression the Redtop was a 180sx motor.

[I H8 UR DSM]

yea it didnt make sense....but hey, he's driving his moms car ; )

[Cattalbus]

[I H8 UR DSM]

jesse, you guys got any pics of the shop front, is it that three bay garage that was posted like over a year ago when you were just moving into it? you guys should post up some more shop pictures and shop rides.

redtop is 91-94 Silvia and 180sx, Blacktop is 94-98 180sx

will it fit in a prelude? Not without a LOT of money...

a black top is NOT a s14 SR20DET, it is a late model s13 motor...

its an honest mistake though :icesangel

The most significant difference between the red and black top motors that I "discovered" is the way the head is built. The redtop has what is called a "high-port" head, and it's widely agreed that the redtop will flow better, but that you'll only really recognize the flow differences in extreme states of tune.

If you're looking for an engine to just drop in and go, then a black top will probably be a better bet, because it will likely have less mileage, and potentially a larger turbo.

For what it's worth though, I wouldn't just drop an SR20DET into anything without pulling it apart and inspecting the major pieces (bottom end, pistons and valve train), with the intention of replacing whatever looks worn. Any engine you get is going to come out of a wrecked car. And anyone driving a car hard enough to wreck it is probably flogging the $*&@ out of their engine.

once again A BLACK TOP IS NOT A S14 MOTOR

a black top is a 94-98 s13 SR (exactly the same as a red top, same turbo and everything but newer and with difforent ECU coding) not to be confused with the s14 SR which also happens to have a black valve cover.

[lessthanjakejohn]

the S14 cover is also notched in the back

Go with the S13 blacktop if you want to strap on a turbo kit and go, red top if you are rebuilding.

Hey drakon, i've read the sticky and it tells you the specs of both engines which are almost the same but im wondering why someone would buy the blacktop for my expensive over the redtop. I know some people would just rather have it newer, but is there really any effect of it being older?

Oh Blacktop > redtop :pface

well if its older, then its been subject to more abuse. Its also been sought out more, so there are less good quality older motors left. If they are the same mileage, then the rubber components still will age and I read somewhere that the gaskets will recess from their holdings if it hasn't been driven for a while.

thanks thats all i need to know.

[JESTER]

Red's pretty.

[BuudWeizErr]

I love my red headed bi+ch

[Drakon]

Potentially the blacktop is gona have less wear on it. But i havent heard anything about red's being crappy or anything cause they are older. I mean, most people on here wouldnt be buying redtops if they were gona break. Make SURE you get a reliable dealer and you should be ok with either. but really the s13 red and black are close to the same. you pay more for the black cause its newer.

[Drakon]

Oh and one more thing. you never know if your getting a first year black or a last year red. when u buy it. so it might be a 98 blacktop.....but then again you could be getting a 94.

[solid]

DAMN, haha dude i've been stuck on this question for a while and right when i thought i got the answer i dont. Everyone wants to save money but if spending money to make the redtop more reliable and spending as much as getting a blacktop then i would just get the black. So which engine do guys think i should get.

[Drakon]

well what i was saying is that you might get a blacktop thats only 1 year newer than a redtop but if ur not TOO hard pressed for cash deffinatly get a black. i think its better for a s14 too

[hokiruu]

Its an engine, not a motor. If you want to have something that has probably not been sitting around as long, has good stock power and is a little more high tech, an s14 is good. I just got mine and its so new I can't believe how clean it is. I guess we'll see how it runs next week...

[Drakon]

who called it a motor?? duh its an engine. k anyways.

hiroku, you have a s14 SR not a blacktop. Solid was asking about redtops vs blacktops. You are right that a s14 Sr20det is an improved engine. solid how much do you have to spend on the engine? and your going to want to replace all your wear and tear parts no matter what u get.
