redtop blacktop sr?

[srkxxdenjin]

i know this is a stupid question but whats the difference from a redtop and blacktop sr? cuz im planning to do a swap on my s14. whats the difference besides the price?

[johngriff]

the s14 black top? iirc there should be a faq around...

[skylindrftr]

depends what versions of those two engines you are talking about...

[Okinawandrifter87]

The only difference is probably to... SEARCH. Lol you had it coming with a question like that. Easily covered. All you type in the search bar is SR20det.

The search button is the difference in price

Valve Cover Colors:

The colors of the valve covers are related to the year the engine was released.

Color /Model /Years
Red.. S13/180SX/Bluebird/Pulsar.. 1989-1994
Black.. S13/180SX.. 1994-1998
Black.. S14/S15.. 1994-2002
Silver.. Avenir.. 1995-2001

S13 Black top - Came from 180sx's post 94 (Garrett T25G turbo)
S13 Red top - Came from S13 Silvia and 180sx pre 94 (Garrett T25G turbo)
S14 Black top - 94-98 Silvias - Variable Cam Timing aka VCT was introduced (Garrett T28 bush journal bearing turbo) Only the JDM engine came with a ball bearing turbo.
S15 Black top - 99-02 Silvias. (Garrett Ball Bearing T28 turbo and 6 speed transmission)

Are you referring to the Japanese market vs Australian or European market cars?

[Mlogue84]

Both, so for instance if you bought an 1999 s14 Silvia or s15 in Europe or Australia you'd get an sr20det with a bush bearing turbo. But in Japan you would have gotten a ball bearing turbo.

if you're lookin to get the s13 SR20 redtop or Blktop reguardless of color, dont have a power difference.

redtop being the early model and Blktop being late model SR20's(not including s14/s15 SR's) as stated above

IMO if were going to build an SR,Id go with an s13 redtop/blktop.

[daryl337]

The s13 tyedye top is by far the most powerful.

[ManoNegra]

Been discussed before plenty.
In a nutshell: planning to mod? Then go for the cheaper (RP)S13 redtop/blacktop.
Thinking of staying stock? Then S14/S15 SR is the way to go.

But imo S13 SRs in S14s are lame. Stick with the SR that matches your year, everything - fmic, wiring, etc - will match better.

if s13 srs in s14s are lame, how come i see alot of them on this forum?

people are cheap and try to save where they think they can. but whatever, do what u wanna do. if you plan on upping ur cams significantly then just go s13sr route and dont deal with the vtc shit. u want a moderate street machine get s14sr. i can go on and on on the pros and cons of both motors but u have to decide what you want to achieve in the end.
