RB20/25 Top Mount Manifolds

[Yellow4g63]

OH and Yellow4G63 that link was dead... try again i wanna see what that was.

Worked for me.

I bought one of the e-bay knock offs and surprisingly the quality was not that bad. it was under 100$ shipped and I have my tig if it takes a dump. It was definitely NOT a 1000$ REAL manifold but after a couple quick modifications I'm going to run it. I will probably not leave it on permamntly but for a 100 what the hell.

[Yellow4g63]

LoL I love when people say "it's $100 what the hell". If something breaks off in that manifold and hits your turbo it's going to be more than $100.

I generally stay away from the Bling-n-rice Crap that comes out of china (I bought the mainifold because I needed the gaskets--couldn't find any cheaper at the time) once I got the manifold I was surprised at the qualitiy--not allot there to fall off and hit my turbo--decent welds inside and out and--fit of the tubes was a little hit and miss.

Yep the quality is actually decent. Fitment sucks though. Thing is how many RB XS manifolds have you heard failed? I haven't heard of one.

If it was decent you wouldn't need to anything to make it fit right. But for a $100 what do you really have to lose?

What do you guys think of these? Are they the same as XS or what?

Kinda reminds me of when people try to turn up the boost without adding more fuel and they end up leaning out too much. It doesn't help to take shortcuts when your investment is on the line.

Those manifolds look pretty decent imo. Both sellers have good ratings on ebay and lots of good feedback comments. I think it would be worth trying them out especially since they seem to be fairly priced. I'd be interested in hearing personal testimonies on fitment and performance.

Yea I think I'll try them down the road when I decide to go top mount style. Just dont like the idea of fabricating a new downpipe. Anywho, I'll get the FLYN one if anything. Sounds and goods good. Also from Australia

The stock manifold modified for the external wastegate works fine and will be able to flow upwards of 600hp. The people that have negitive comments about the logs have never ran a log before. They have heard that logs are not the way to go and that is not true always. It is a cheap modifcation and you dont have to worry about any cracking of the manifold since you are using a thick cast iron peice. I dont see the point of wasting the money and spending $1000k plus on a manifold when you only expect 400-500hp out of your setup. If you want to make the engine look good then spend the money, but if you are looking for a reliable cheap resort, go with the stock manifold and modify with a external flange. It will not flow as well as a equal length tubular would, but then you have those that get a non equal length tubular manifold and are talking negatively about those with the stock cast...in which their manifold barely out flows the stock. If you are going to run a tubular...then go equal length and spend the money on a quality product. I hope to build some equal length tubular manifolds in the near future, since there are no other shops that will make some quality reasonable priced manifolds. $1000+ is to much for a non equal length tubular ****ty stainless steel grade manifold.

The idea of using the modified stock manifold with external wastegate really sounds enticing and feasable if it really does handle up to 600hp. Personally I wouldn't mind a little bit of flow restriction if it would save me several hundred dollars over getting an equal length tubular manifold especially if it looks as good as the one above. Not to get it twisted, I do admire the equal length tubular option; however at the same time I would like to be able to save some $$ in order to use for other mods or dyno time for tuning.

Weld quality buddy, not fitment. Yes fitment DOES suck. But like I said, how many RB XS manifold failures have you seen?

That's right...zero.

So unless you have hard evidence of the RB manifold failing.. don't knock it.

(BTW I wouldn't recommend anyone buying this manifold :p )

He has a point over all the fitament is bad, when I bought a SSAuto Manifold for my RB20, I went out bought a titanium bit and reemed out the holes to fit the studs on the motor. After that it fit damn good. As far as XS Power Turbos themselves.... stay away from those. Turbines snap off and shoot shrapnal down ur exhaust, so of the turbos split right in half hahah! Thats no good lol.

Really 600+ Hp huh? Well I'll be using my Log until you fab up those equal length manioflds lol. I do agree that the $1K price range is steep for a non-equal lenght. I mean the only name brand quality equal lenght manifold out there still avalible for the Rb20/25 that I can think of is the Greddy on on Nengun Performance. but then again its $1500

i wasnt saying the log is a waist of time, i was saying with my experience i would "think" it would be a waist of time on a rb. but looking around and seeing these mani's that are out there i bet we could almost make a log as good as the ssac unequal length mani. the reason for coming to conclusion of this is seeing one of the ebay mani's in person and the runners are small. i bet a log that has decent size runners would be good, well alot better than the stocker, and could be made for cheep.

I have a video of that happening on the dyno with my friends dsm.... compressor housing split right in half....guess they cant stand 30 pounds of boost.

The matirals to make the log are prob going to cost more than the SSauto manifold. Then add the labor and time. So cheep I doubt it, but not as much as a non equal length manifold yes.

Hey put that link up or send it too: [email protected] I gotta see that.
