Does anybody know if the RB26 Valve covers willl fit on a RB25?

Full-Lock · 01-23-2008, 10:24 AM

they will with a new intake mani and a few other changes

im not really sure exactly, but ill let someone else chime in who knows a lot more than me.

i have the spark and cam covers for sale from rb26 too if you want them

They will fit, its a good idea to use a side entry intake manifold as it will make things easier but they will fit with a little reworking of the PCV setup.

coreansurfer · 01-23-2008, 11:28 AM

but what's the point?

azndoc · 01-23-2008, 11:29 AM

Damn it if the Tomei RB26 crate motor doesn't look sexy.

I'm drooling over here.

Siizzzoooo · 01-23-2008, 11:34 AM

I'm putting those on my RB25 as well, I'm only doing it because the RB26 covers look way better

Felix180sx · 01-23-2008, 11:36 AM

I dont like how the timing belt cover is really huge, the valve covers dont blend with the timing cover. I like how the sleek rb26 valve covers transition smooth. I dont know I just like the little details

To do it right you need the valve covers, upper timing cover AND the timing cover backing plate. Not sure if the lower timing cover is different, I think it looks the same.

As they mentioned you will probably have clearance problems with your J-Pipe hitting the valve covers. For all the work you're going to do to pull this off, I think you might want to consider the clear upper timing cover (which are designed for RB26):

The RB26 covers look sexier. Explain what the point of 180sx type-x tail lights are?

yes, 26 cover looks nicer, but putting a 26 cover on is false advertisement.

Im gonna switch the intake manifold to greddy plenum, and run front mount intercooler.

LB.Motoring · 01-23-2008, 11:57 AM

hahaha fakie rb26's

I love it.

it would look awesome, but I wouldnt do it untill you got the motor in, and get it all running, Im tired of seeing garage art from everyone.

I guess Im glad I sold my rb25 when i did -.-

i need tires · 01-23-2008, 12:18 PM

i saw do it.. its nicer.. just figure out someway to get the rb26 part off of it.

and perhaps put rb25 on there.. but it will fit.. some way some how.

Full-Lock · 01-23-2008, 12:22 PM

who cares

rb26 is way more visually appealing than an rb20 or rb25

yep ha ha i was almost about to put some 26 covers on my RB20 but then i sold it. plus if i ever did that, i would have to have a nice HX35 or something equivalent to be as fast / power full as a 26 wouldn't want ppl thinking they beat an RB26 when it was only a stock 20

Irukandji · 01-23-2008, 04:52 PM

I would do the same. Shit, what's the difference between swapping valve covers and front ends? Nothing. "yo that aint no silviaaa"

240love · 01-23-2008, 05:12 PM

dam If these would fit the rb20 I would do it

cefirosliderRB2.7 · 01-23-2008, 11:44 PM

well i have full 26 internals...so im allowed!!!!

yes it does fit. i stated that in my earlier post.

stricnynel0s · 01-26-2008, 09:58 AM

so u cant run those with rb25 cam cover ?

Felix180sx · 01-24-2008, 03:25 PM

What if you scraped off the rb26 off the timing chain cover, would that be "acceptable"...lol

lilskyline240 · 02-03-2008, 12:34 PM

Im running rb26 valve covers and cam cover with my rb30 build. Since i used a rb25de head. They fit great. Just need to do a bit of modification to make the cam cover to fit

*MELLO*SOS* · 02-04-2008, 09:27 AM

Just search RB26 CLEAR TIMING COVER on ebay or google. It's just a clear upper timing belt cover, it says 'rb26' on it. It requires the RB26 upper timing cover backing plate to work on 20/25.
