Lookie what I found...

[300Plus]

I remember seeing this intake on a post but figure I'd post it up, someone may want to buy. looks less impressive off the car. http://cgi.ebay.com/ebaymotors...QrdZ1

[krayton]

nice one. heres one on a rb20. id rock it. too bad i invested in a intercooler with in/out on same side. i like that one too, cause the top pelnum part is not that bad to take off

[Wulfgang]

The one on the 20 looks much nicer. Looks OEM.

That thing on ebay looks like it was made by some guy in high school shop class. For $350, I'd expect better quality.

Exactly. But I just noticed the one on the 20 is using the stock "recirculating valve" I wonder why. either way it looks far better then the ebay one.

Hrm..... That design looks fishy, i wonder if it distributes air very well. . . .

[ehacker01]

I am the one that made that. I know it doesn't look as good as the one in the pic. Actually I modeled it after the one in the pic. They put a lot more time into smothing out the welds. If it were going on my car, I would have smoothed out the welds but since I was selling it I wanted to make sure that there were no leaks and didn't want to reduce the integrity by grinding it down.

[ehacker01]

oh and by the way, the welds look waaaay better in person. the flash and shadows made it look way worse.

It should distribute just as well as the stocker.

No offense but it looks useless to me... sharp 180 deg bend for air = worthless...

Well that must be why a 5.0 makes NO power. have you seen that intake that people make plenty of power with? Obviously not with this statement.

Ok, well it looks a lot better then. I didn't know it was just a one-off, backyard style project by somebody on this forum. I thought it was just somebody else trying to take advantage of ebay with some cheaply manufactured part for RB's.

With regard to the airflow, I don't really think anyone can give a thumbs up or down without seeing flowbench comparisons to the stock mani. Too many variables. Yes, we can make some gross generalizations, like saying a 40 mm TB is too small, or that velocity stacks are usually better than no velocity stacks, or that polished pipes flow more than rough pipes. But in general we cannot say whether this or that design has more flow potential. Just look at the HUGE variation in OEM manifold designs... like someone said, what about the 5.0 manifold?

[ehacker01]

I would also like to add that I am using the bottom part of the manifold to make a forward facing R.I.P.S style manifold and didn't want the top part to go to waste...So I figured why not modify it so someone else could get a forward facing cheaper than the $800 greddy unit. If anyone from this board would like to purchase this I will also gladly discount it on exchange for you factory plenum. I usually just stick to motorcycle bodywork/fabrication but decided to try my hand at car parts.

[rbsileighty]

No need to get angry... just saying (probably in a to harsh manor)

That is a poor design as well... and don't tell me a Cobra manifold (the one you have pictured there) put out a lot of power...

95 5.0L Cobra put out 240hp stock... 48hp/L

Smooth large radius bends is definitely part of the reason why the stock and the FAST manifold designs for the 5.7's are so good:

52-72hp/L stock...



Fast manifold is considered one of the best aftermarket manifolds for the 5.7L and it still has the same design:



Even the Cobra (still not the best manifold but much better) went to a similar design when it switched to the mod motor:

66 hp/L



I'm just saying that is not an efficient way to plumb air... switchbacks happen, but should be avoided... and especially tight radius ones. This is based off of fluids mechanics...

[ehacker01]

I'm not mad at all. didn't mean for it to sound that way. my point was that people still can make 450+hp with the 5.0 or the trickflow 5.0 manifold. Yes the LS1 and Cobra design are way better but the older style still works the same as I believe this one will for our cars. Only one way to tell. Dyno it, but I don't have the time or the funds right now.

[skillzilla]

Im sure Nissan Japan forgot to R&D this design:

[rbsileighty]

Nope... but it's definitely used for packaging... and why the race VQ manifold looks like this:



Where did you get your ARP head studs from for the 20 Skillzilla (just a quick side note)?

[300Plus]

We may have a few upper plenums laying around. But keep this going... I'm enjoying the read.

[skillzilla]

They are the same as SR20 main studs, which ARP carries in stock.

And I wonder where they copped the design for that race manifold...



hahaha not exactly, but you get the idea...

Got an email address?Intrested in purchasing

[ehacker01]

[email protected] or you can just send me a message through ebay.

[300Plus]

Hey hey hey , I think I should be in on this deal, I mean I did find you a buyer lol j/k man. I still owe you for the wiring help

[RBTALLY]

What would most of you prefer for a tb ... the stocker or the q45 tb. I ask becouse I have played aroound this afternoon and did this, but do not know what tb to use on it

[rbsileighty]

RBTally... are you still using the stock lower intake manifold?

[300Plus]

RBTally... are you still using the stock lower intake manifold?

No he isn't, He is using his complete custom intake. but He's messing around with an upper intake for the stock bottum which is whats in the pic.

Looks good man!

[RBTALLY]

RBTally... are you still using the stock lower intake manifold?

not on my car ... like 300+ said this is just something I played around with last week to see what could be done, but there was no intrest so i built one that used a stock tb and one that used a Q45 tb..... like I said just to see what could be done. one is sold the other i will put on the shelf with a few other sheetmetal mani's I have built and test it some day ... just to see what it can do.

[Imissmyturbo]

I'll test one of them out for you. Are you planing on keeping the stock Idel control valve on the intake?

[RBTALLY]

yes it will ues the stock iac... how quick can u get it on a dyno?

[Imissmyturbo]

I would have to redo my charge piping from the intercooler to TB. I could wip it up in on a saturday. I should run up and do a quick baseline run and then check after. I am making around 300-325 whp
