Larger cams will always give you a noticable idle change... you'll hear them loping all the time. a set of cam gears and a good tuner can smooth it out for you to an extent, but you're still going to notice them. When ever cops are around, i turn my A/C on, and it smooths my idle down to almost stock on my Cosssies. Cossie M2's don't require Valve springs, but the M3 and Kelfords do.

As far as the best o2 out there... Pound for pound, you cant beat the EPM o2 dump. i have it and love it. If you don't mind the noise of the wastegate opening under boost, go this route, if you want to keep things quiet with a traditional o2 housing, go with Invidia.

and for porting the hotside, its still going to make a difference even on the 10.5 hotside. ABY ported my FP Green to almost a mirror finish!! and i have seen others with ported hotsides on the stock 9 turbo get gains off it when combined with a ported or aftermarket Exhaust manifold.

Good luck. {thumbup**

Does anyone have the gains from installing an Invidia O2 Housing?
The Stainless Steel Fabricated O2 Housing that buschur sells is rated up to 15hp.

 

ok im new to the evo game. So im modding as i go along. which FB turbo is better i have been told that the fb green is a waste of money because i have to use race gas to get 400hp out of it i want to stay on pump gas no meth inject etc. I been reading about the Fb red dont know much about it at all. Never heard of Fb white. My goal right now is 500whp that might change but i want to make sure whatever turbo upgrade i get. if i want to turn it up it can do 500 to the wheels otherwise its a waste of my time and money to get it. Again i dont want race gas in this engine. I was told to the the HTR 35 something like that. its a 3 grand or so kit. so if i could get a turbo that will do the same output for less cash ill go that route. i really dont want to mess with the ported o2 yet i rather get my turbo and all the port stuff install at once so i dont have to take it all off again. what cams should i get i prefer not to upgrade the springs retainer etc, but if i have to i might beable to get my local nissan dealership to do it. they love my cars and i bought several from them. they are the ones that said they will do my cam job for me. so im in the market to get my next part here what i got already

3" Nvidia N1 exhaust
testpipe
3" Perrin downpipe
aftermark manifold
Forge MBC
Injen upper/lower pipping
Injen intake
Mishimoto Radaitor
Perrin oil catch can
New sparkplugs

 

Ok, well the first thing, is its not FB, its FP... Stand for Forced Performance. Next, you need to understand compromise. You said you don't wanna use race gas for reach 500 Wheel, then prepare for a rather serious build. To reach that on pump, you're going to need to go larger than a FP Green, and a FP Red. The Green is smaller than the Red by the way. And like all turbo's larger than stock, they are all going to shine when you see higher boost... which requires using Race Gas, Pump + Meth or E85. For 500 WHP on Pump, you need to look towards something like a GT35R. The HTR you mention is actually HTA. I believe Mellon tuning's Evo is using this HTA35R setup and he's doing 500WHP on pump gas

 

that would be correct sorry i was at work lol and rushed typing lol. i figured that what is the max outputs of the Fp series turbos anyways.

 

Yea. haha all good.

so i mean you gotta figure out the over all goal you are going to make with this car... power feind only on race gas, or a serious conteded on pump and/or E85

 

true see i dont know 500 seem like a nice number to crush alot of cars out there. Now if i dont meth injection or alcohol or water over time isnt that bad for my engine as a whole. Explain to me the goods and bad of injection. i see alot of people have running it but then again i also see avoidance of it. what the true deal with it.

 

Meth is good once you have a build motor. I wouldn't recommend using meth on a stock motor.

Like ASIXMRSE said, its going to be hard to reach 500whp unless you go with GT35R or higher turbo kit. You can easily reach the mid 400's with the FpRed, cams, FMIC, walbro 255 fuel pump and a good tune with the current set-up you have now.

 

let me edit my mod list i left stuff out lets do that again 2006evoixmr

3" Nvidia N1 exhaust
testpipe
3" Perrin downpipe
aftermark manifold
Forge MBC
Injen upper/lower pipping
Injen intake
Mishimoto Radaitor
Perrin oil catch can
New sparkplugs
Aps Intercooler
hks turbo timer
Sunpro boost gauge(i have autometer as well)
Walbro 255 fuel pump

I swear everytime i do this list i leave stuff out lol. Now tell me about mid 450whp then.

 

My brother has the FS635 kit in his IX. He said right now he's at about 500 hp but having problems with spark. I'm not sure of the details, but once he gets his tranny built up he said he should be able to get about 600 out of that turbo.

My overall goal for the car is to be a full blown dedicated drag monster. This of course will not occur until I win the lottery{thumbup** 400-425 is as much as I want to go for now. I had plans to get the green, but then the red came out awhile ago and I'm sure with that turbo 400-425 is very possible.

Wanting the red is another reason I'm thinking of holding off on the on doing the O2 housing and just worry about it when I get the turbo, probably late summer 09. It looks to me the Red requires a different MAF pipe than stock, does anyone know if these pipes are custom only or are they sold?

Yes, I've read good things about KevinD on EvoM. I'm about 3 1/2 hours or so from there and would definitely consider going to him.

 

A million horse power

 

RockmanX I got you guide and looked through it, I'll definatley be pulling the radiator if I decide to do the O2 housing now. I does look quite easy. I like the way the radiator chrome spices up the engine bay and of course it functions better than the stock. I was looking at mishimoto's website and they offer 2 models one for 4,5,6 and one for 7,8,9. The one for the 4,5,6 models looks like the where the upper hose connects is more to the right, moving it away from the the exhaust manifold and all the heat it produces. So my question is would the radiator for the early models work in the newer with simply a straight upper hose or would it require some custom work?

Again good work on the guide RockmanX !

 

lol, the only thing left is the o2 housing, Camshafts, Camgears and the FPred, and you'll be on your way. Don't quote me on this but you should be around 440-460whp after the tune.

Try it, see how you like it. A 400 whp car is pretty powerful for most cars today.

Should i hotside 10.5???? or does the red come with all that. what do i actually get when i buy a FP Red. just the turbo and i have to bolt it in to my orginal equipment. or does it come with wastegate turbo hotside turbo outlet????? now what 02 houseing should i buy then camgears and camshafts. I know camgears does not matter i was just gonna to get some Greddy ones for flavor colored blue

http://cgi.ebay.com/ebaymotors/Gredd...Q5fAccessories

and then im still trying to understand what camshafts to get im confused about that one

Hks
Conworth
Kelford

if i spell something wrong i dont care you get my drift. Now DO I NEED TO CHANGE MY SPRING AND RETAINERS. you guys say kelford is the best but you have to update them s&r to run them??? What size is the best size 272 280 or what of course if i updated the s&r i can go bigger i know that. but if i dont have to touch them i dont want to disturb them. almost like installing the apr heads most say its a waste of money and could cause a oil leak. yes i know thats using the 1x1 method and not replacing headgasket. same concept of breaking a factory seal. so what you think

 

I'll get back to you in few about the FPred and the accessories that comes with it.

As for the Camshafts, stick with the Kelford 270 which is good for 350-500 and DOES NOT REQUIRE VALVE SPRINGS or RETAINERS. Just drop in and drive.

Its up in the air for the best O2 housing, many people say Invidia but I have yet to see any true data on the gains, but I bought the BR Stainless Steel Fabricated and Ceramic Coating (prevents rust) O2 Housing and its proven up to 15hp.
