REDTOP vs REDTOP

[thepest]

So I found out that there is 2 type of redtops. the only difference is the head as far as I can see. So is the newer redtop with the cooling fins better by far then the older one?

[projectRDM]

No.


Welcome to 1991.

[mrmephistopheles]

just an age difference, that's all. You'll never notice it.
1993, Russ.

Close, I don't keep up much with SRs, too gay for my taste.

lol.. its not possible for people to know about this back in 1991...

seeing as how the S13 blacktop sr didnt come out till what.. 96? something like that.

but yes.

to the original poster.

get the third version of the redtop instead, it is the best one. came with 275hp and 300ft/lb of torque stock and was endurance tested at the nissan factory and it was able to maintain a steady 8000rpm for 10 hours straight without any catastrophic failure.

it is marked by cooling fins that are slightly slanted to the right on the head of the motor, and a red valve cover that has a slight tinge of orange in it

hope this helps :)

yes it uses a T26...

/sarcasm

is this for real? All the S13 redtops are pretty much the same, minor differences and of course, as MrMeph mentioned, really the biggest factor is age.

ok, thanks for the info.

If they wern't 15years old theres alot of differences between the two.


but they are. so your rollin the dice no matter what.

There is a slight discrepancy in port hieght from inlet to valve seat on the Finned Late model heads and the Unfinned heads. The unfinned heads are just IMO. But for some reason the Built motor im doing it finned. The un-finned head is longer ports barely or some crap. I could be talking out of my ass. The Black top s13 is lower port and the VTC heads are the shortest.

[McRussellPants]

the finned redtop has the same internals as the early blacktops.

[thepest]

OK, does anyone have actual specs? I mean everyone has different info about them, but all and all the finned one is newer so it would be a better buy fo rthe same price. right?

[Cashizslick]

Paint the finned redtop valve cover black, and resell it to some newb as a blacktop . . .


. . . any way to tell if this has happened (besides fresh paint on the valve cover)? No sense getting scammed - any dates/numbers to check on the motor itself?

LOL . . . that is true.

i'd just get the newest one, type x black top, lower mileage, the ecu can also tell you what year unless someone decides to fvck with the harness to run different ecus which does happen

or just rebuild any old redtop, and you won't have to worry if it comes with fins or not

[TheTimanator]

you can also tell the o2 sensor. Skinny= redtops Fat= blacktops... Although I have a fat o2 sensor and it has a red valve cover. I should check the ecu sometime to what it really is...not that it matters to me.
