Megan DP w/ Greddy Turbo extension/elbow pics

[redline19]

I recieved a Megan downpipe and a test pipe or resonator today for my s14 w/ s14blktop sr. Both are pretty good pieces for the money. I also recently bought a Greddy turbo extension to go with it.

Only thing that bugged me was that Megan reversed the dp flange connecting to the Greddy turbo elbow. I'm not sure if they made it to match THEIR own kinds of turbo extentions, but its just a little off with the Greddy flange. Its not that big of a deal, the flanges just have this little groove that is mismatched, but it would of been nice if they were the same. I have some pics to better show what i'm talking about:









With the gaskets they provide, it seals everything up pretty good so I don't really see a problem with it. Just fyi for people who are looking to get these, might want to look at matching the Greddy ext. with a Greddy DP or a Megan turbo ext. with a Megan DP.

yea it should still seal alright and not leak. im looking into a new o2 housing, is that greddy one divorced? how much? where from?

thanks

[redline19]

Yes the Greddy one is divored. I got mine from hopupracing.com for 189 shipped. I think theres a few more sites that sell it for about that price shipped also, i think one of them is projectnissan.com. the kits nice, for s13 or s14 bc they have a adapter for the smaller o2 sensor or a bigger one for the s14's o2 sensor.

[jt15833]

yea i think i may take my chances with an ebay divorced o2 housing for 70 shipped tho

[redline19]

good luck with that

i have the same setup, and was also wondering about the alignment on the wholes.... well it turns out since my studs wouldnt go in straight, the nuts fell off the turbo ext..... only 1 is holding, 1 is gone, and 1 is moveable by hand.... soooooooo im gonna get a new downpipe....

really? the one pictured on their site doesn't look like the GReddy unit. it's not divorced (can tell by what you see through the O2 sensor hole) and the O2 sensor hole isn't right at all. it puts the O2 sensor directly into the exhaust flow. $189 shipped is a great price, but is yours like pictured or is it divided housing w/ the slanted O2 sensor hole?

[redline19]

yea I know what you're talking about. But it is the greddy divorced version downpipe. It must of been something wrong with the picture but the one I got is how it looks in the pictures I've shown.

btw, I put in the turbo extension in the other day and man was it worth the buy. The spool up is definately a lot faster, no lag - all spool. If I had to estimate it, I would say maybe 500 Rpms quicker at least. Theres less of a bottleneck so more air can go thru the 3" inch free flowing exhaust.

[95lstegman]

wow, really? that's what i want to hear, man! i've got a redtop with an E5 computer and a dead skinny O2 sensor, so for x-mas i'm rather sure i'm getting (from my woman, no less!) a GReddy turbo outlet and a fat O2 sensor. i'm just stock swap with an exhaust though, but hopefully i'll get better gas mileage from the new O2 sensor, better power and spool from the larger divided outlet, and hopefully it won't be too loud considering my exhaust is 1 big 3" pipe all the way out other than the turbo outlet.

My greddy turbo outlet:

does the greddy elbow clear the steering colum?

[95lstegman]

does the greddy elbow clear the steering colum?

yes. that was one of GReddy's design criteria. i believe that is why it's not a semi-divorced outlet like HKS, which does not clear the steering shaft.

I got a GReddy Dump for $150 shipped from someone abandoning his project. It's a really high quality piece, and is visually obvious in how it flows much better than stock. Mates up to my CIP downpipe (it's a MR with a flex joint nicely tig'd in for the same price) perfectly, except my DP flange is upside down too. Still seals 100%. Use a thin application of exhaust flange cement if youre worried.

The Greddy dump comes with stainless studs but no nuts so I went to the hardware store and had to get some zink coated 8.8 stuff... for some reason noplace carried what i needed in stainless. Couldnt get a socket on the nut by the frame rail but thankfully id gotten a set of crow's feet and flex ratchets previously so now everything's nice and tight.

only complaint I have with the CIP (MR) Downpipe is that the complimentary exhaust hanger bracket is about 1.5" from being able to hook up to the mount that sticks off the transmission. some long bolts and a bunch of thick washers should make up for it tho.

in my research ive found most all downpipes are 2.75" inlet diameter and 3" out. The greddy elbow is 2.75" out to match the dp inlet. An SSAutochrome/TurboXS 'HKS Style' dump looks fancy, but its 2.5" out and the O2 sensor is excessively and immediately in the path of the fleeting turbine gasses.. Not to mention it will probably have to get decked cuz the pot metal flangees warp badly as they weld the pipes on.

yeah that's pretty much the #1 reason i want the real GReddy. i'm just worried about it making the car too loud. right now i have full DP no cat and exhaust all 3" (except for the inlet of the DP which is 2.75") and the tone and volume are perfect.

[Neil]

id think it wouldnt get much louder... you might be able to hear the turbine in the exhaust though

[95lstegman]

hehe, i hope so on both accounts

[ReD*PiG]

So You guys think a dump pipe makes a big diffrence in Horespower, or just make the turbo sound louder while spooling?

[codyace]

A dump tube will be loud (especially an open one), however it will increase wastegate response and free up some power at the same time

A turbine extention/outlet (or o2 housing, or j pipe) will help spool up time, free up power and help the turbo breath better.

[redline19]

does the greddy elbow clear the steering colum?

just barely on my s14, and i'm talking damn close. but yes it clears it.

[Neil]

What size turbo is on an STI? my buddy just put a full catless exhaust on his and you can clearly hear the turbo through the exhaust as he pulls away at slow speeds. pretty neat sounding.

usually the greddy unit comes with all necessary bolts and nuts along with a gasket and an adapter for either fat s14 o2 sensor or skinny s13 o2 sensor.

and also the turbo outlet isn't really louder per say on my car since I already have the Hi power exhaust which is already loud. It just makes it some a little bit deeper and the exhaust tone is smoother imo. Also the turbo spool is a lot louder if you have a cone intake element which most people do. I got the bb s14 turbo so it spools up pretty loud. lol I have to admit, its guilty pleasure cracking the window just a little to hear it spool up, even though it's like 30 degrees here in new york.

Hey,redline where are you in NY,Im on long Island,Bayshore.

[redline19]

yea man, i'm in ny around queens. I used to live in long island, go to school in westbury

dammit i do that all the time, no matter what time of day or night. i LOVE listening to my exhaust tone. the SR's exhaust note is teh SEX.

Hell Yeah!!
