GReddy turbo kit FAQ - Page 5

PhantomSi · 05-16-2008, 02:47 AM

This sticky says: 6. Spark plugs that are 1 heat range colder than stock. Personally, I recommend NGK brand plugs, part number BKR7E-11, gapped to 0.030".

I don't know what the spark plugs you bought but im assuming the ones that are one step colder are the ones he suggested. He also suggests you gap them but i dont think those are iridium.

nelsonr31 · 05-16-2008, 01:25 PM

I doin't think the plugs he bought are iridium so obviously there's gonna be different part numbers, and I don't want to gap iridium plugs if they're not suppose to be gapped. It would be nice if someone would chime in that knows what I'm talking about.

Just curious if anyone can tell me the dimensions of the fmic that Greddy includes with this kit?

Kronos_32 · 05-19-2008, 08:30 PM

Hey guys I have a thread on this section and I wanted to post on here about the exhaust sizes. I currently have a vibrant 2.5in and Im planning on getting the greddy kit this summer/fall. what will my #'s be compared to if I just get 3" straight pipes?

You need to get a 3inch all around, or you wont get good numbers.

you need the most flow as possible my man.

Yeah thats what I was thinking. I want to get away with it but I need the good numbers and I dont wanna run wussy exhaust if its gonna hurt that much. one of the guys that works on K series cars at my local shop said I could get away with it, but i'd probably only be pushing ~230-240WHP

soxfan143 · 05-20-2008, 05:17 PM

I don't think you can even get a 3" downpipe for the GReddy kit. Or is the downpipe already 3"? I'm picking my kit up in 28 days and counting and I would like to know this. Thanks guys.

nelsonr31 · 05-20-2008, 05:53 PM

Mike, The down pipe that comes off the greddy turbo is exactly 3 inches OD, I just went to the garage and measured it.

The C Tripp · 05-21-2008, 09:33 PM

is there any way on replacing that airnix intake with a CAI?

If anything a longer pipe with more bends and/or angles going directly into the turbo will impede airflow. You want air going directly into the turbo to be as freely moving as possible. Also, the benefit that you would get from a CAI setup on a turbo'd setup will be less significant than on an N/A setup because the air runs through the intercooler and is cooled regardless before it enters the engine- that is assuming your intercooler is doing its job efficiently.

Thanks Nelson. So that would make it 2.5" ID roughly. Right? Is there any companies that make a 3" down pipe for this kit yet? Maybe I could get one custom made. I'm probably going with a 70mm cat back as soon as I recover from buying the kit and a Tru Boost guage.

nelsonr31 · 05-22-2008, 08:24 PM

NP Mike,roughly 2.5-2.75 ID. I'm not sure if theres a company that makes a true 3 inch DP for this kit, probrably has to be custom made. I actually have a Random Technology high flow cat on order, its a direct bolt on between the DP and the cat back and I believe its 2.5 inches ID. I'll find out tommorow cause thats when I'm picking it up. It already has two bungs for the oem o2 sensors all I have to is get another bung welded on for my AEM wideband. The reason im using this setup is for emissions since its pretty tight here and the cops who like to randomly check if its there. My car is fairly low but you can still tell if theres one there or not, or else I'd be goin with a custom true 3 inch test pipe. Btw I already have the skunk2 70mm, now that is one nice ass exhaust. Here's a pic of the Random Technology High flow cat. Now my question for you Mike is where do you think I should install the AEM wideband O2 sensor? Between the first bung and the cat? If anyone else has any input as to where they installed theirs this information would be great.

PhantomSi · 05-23-2008, 01:29 AM

I think that the recommended spark plugs should be updated.
It says: 6. Spark plugs that are 1 heat range colder than stock. Personally, I recommend NGK brand plugs, part number BKR7E-11, gapped to 0.030".
according to other threads, those are actually stock heat range. The ones that are one step colder are BKR8E.
I actually went out already and bought the BKR7E-11 spark plugs. i guess i gotta go exchange them.

The closer you get the wideband to the engine the more accurate reading you will get. Try and put it as close to where Honda put their AF sensor. This would be the optimum position as Honda would out it in the best spot for reading AFR's. If youput it too close though the heat might be too much for the sensor and mess it up. But if you put it yoo far your readings will be off. the further you put it away the leaner the mixture will read because of dilution from cleaner air. Like when a Dyno shop uses a sniffer at the tailpipe the reading is always leaner than what is actually there. As long as you put it before the catalyzer you should be OK. I would personally put it right near the stock location as close as I possibly could.

And about the Skunk2 exhaust, have you had a chance to hear it with the turbo yet? I need to know if it's going to be obnoxious because I really can't have an exhaust like that in my state because the police are brutal here. MA wants to pass a law where any exhaust mods are illegal. Basically any aftermarket exhaust part is not legal at all and I will be fined and I will NOT pass inspection. So any exhaust that is super loud will not work for me. I would love to get an exhaust that sounds like the GReddy EVO II but in 3" or even 70mm. I heard that GReddy is releasing a 70mm catback for the Si this summer. But I don't know how true that is. The GReddy EVO TT is a sweet setup but I can't find a listing for our cars for it.

nelsonr31 · 05-23-2008, 07:28 PM

The turbo is still not on so I have yet to hear it, but if the police are that bad then maybe you shouldn't get one or maybe you could do what I did to my skunk2 70mm just for day to day driving cause the cops here are pretty bad for that also. I installed the skunk2 catback and drove around for a week to see how I would like it, It's a real nice sounding exhaust, the best IMHO but its decently loud if you have a heavy right foot. So what I did was I unbolted the skunk2 axleback, threw my stock axleback in the trunk and drove to a muffler shop, you wanna talk about loud now that shit is ******* loud LOL. anyways I had the muffler shop modify the flange on the OEM axleback to bolt up to the skunk2 midpipe, it's a hell of alot quieter for daily driving but still has a nice rumble to it and IMO sounds better then the skunk2 axleback on with the silencer. Whenever I plan on going to the track all I have to do is unbolt the OEM axleback and bolt up the skunk2 axleback and presto instant sound LOL.

soxfan143 · 05-23-2008, 07:32 PM

Nice. But wouldn't the decrease in pipe diameter cause problems even in an NA configuration? Who else makes a 70mm catback for our cars? Or a 3"?

nelsonr31 · 05-23-2008, 07:39 PM

If you actually look the pipe diameter on the OEM axleback its pretty big(NOT 70mm but not to far off) but I'm sure the dyno would say I'm losing a little bit of power, thou the butt dyno doesn't say that. I have had this setup for the past 6or so months and I have absolutly no problems or complaints about it, and the best thing is not one ticket nor getting pulled over for a loud exhaust. I don't know of any other companies, again it would probrably have to be another custom thing. BTW Mike here's a picture of the little ****** LOL

soxfan143 · 05-23-2008, 07:58 PM

Haha. Nice bro. I'm so jelous of you right now. I'm probably gonna sleep with mine under my pillow the first night before I put it in. Hehe. No seriously though. It didn't take us very long to get sick of the NA crap and trying to find a few Whp that just isn't there without spending a million dollars and complaining there is no tuning. I'm done wasting my time with NA. It's just way to aggrivating and expensive. I always wanted a boosted Honda anyway. Now it's gonna happen no matter what. If I have to rob litttle old ladies' purses to make it happen. No no no. I'm just kidding about the little old ladies. Haha.

nelsonr31 · 05-23-2008, 08:06 PM

LOL i know, I have always wanted a turbo Honda. All my cars(& Bike) have been Honda, and 1 of them was supercharged but nothing is like Turbo. NA is too expensive for my blood, the amount of money you would have to spend to keep up to a well tuned turbo kit is unreal, Plus do you notice that none of the turbo guys here argue about 5whp like the NA guys do. The NA guys argue about dyno's like it's going out of style, I don't hear that from the turbo guys. NA is too pitely for the dollar amount spent.
