im not a vtec man so im curious whats the proven gains for using ITR parts on b16's such as cams, intake manifold, jdm exhaust manifold. is there advantages for using ITR over aftermarket?

 

jdm itr header will shut down any other usdm header w/ a 2.25 collector (dc, greddy etc). the itr intake manifold is also a great piece, i'd rather go w/ the skunk2 though. the CTR cams are probably the best bang for the buck, u can pick up some used ones for around 400. and no other cam gives you as much midrange (skunk2 II, jun III, toda b). you can make a b16 quite a bit more peppy w/ "R" parts

 

you can't beat the performance of OEM over AM parts

 

im lookin for proven gains.

 

these are the type r (itr on both sides, not the ctr intake, itr exhaust which makes a bit more power) cams...

here's the jdm itr header vs a common usdm 4-2-1 header...

how's that for proven gains?

 

thats a modified header wich the average person doesnt do and thats a "near" built motor. impressive performance from the itr cams on a GSR head with modifications. im sorry i wasent more specific ... im lookin for the average joe that has basic mods on a B16. b16 please.

 

i dotn know why you're being so critical...but the "modification" on the header was a slight port job that anyone could do w/ a dremel tool. everyone knows the jdm itr header is better than anything other than the mean smsp and hy-tech headers for b series. the ctr cams have a hell of a lot more lift and duration as compared to the gsr cams. they actually have valve overlap (this should make anyone smile...cuz this is GOOD). there's no sense in fighting the numbers man, i dont know why you seem to want to disprove something

 

i dont know why you think im tryin to disprove anything. just show me. itr cams over aftermarket or stock b16 cams on a b16 like orginaly stated.. not itr cams on a built ls/vtec. if the mod to the headers was that easy then why does it state "custom header"(not for sell) ... .maybe its not that easy a mod?

 

i dont know where you saw the "not for sale" part, its not there. its a jdm header w/ the welds redone on the outside, and the inside ported. if you can't weld it yourself, a muffler shop would do it for like 10 bucks. and it doesn't take a rocket scientist to realize more lift, more duration, and more overlap on a NA engine = more power. how much you'll get from bolting them on depends on ecu, other mods, and application. expect to get @ least 15 flywheel hp on a B16.

 

thats all great but im lookin for proven gains.

 

ok...i have a question for you. are you looking to make specific gains or something? or just looking to see what kind of mid range, top end difference you'd get outta the cams/header? i dont see what the hell you're being so picky about, you asked whether or not the type r parts were worth it, you've gotten pretty much the same info over n' over. nonetheless...

Then do the research yourself.

 

im am just looking to understand why ITR cams and other parts are so much better than b16 parts. and why the differances in ITR over aftermarket. i am also tryin to start a conversation based on proven facts on this board other than the usual .." i cant check my ecu codes" or "what muffler sounds the coolest on my riced out hatch" or my favorite "why is my car slow?" i am not tryin to hate on ITR or "disprove anything". i see soo many threads talkin about ITR is good **** .. I know there is one person somewhere in this board that can help me understand why with proven facts.

 

i'm starting to think you're slow or something. you asked for proven facts, and i've given you dynos...and you for some reason you still persist to act crazy. no one here as given any qualitative descriptions of the itr products, everythings been quanitative so far. you dont hear anyone saying, "the itr muffler sounds nice" instead, if you bothered to look around you'd see that a itr exhaust on a modded dc2 only makes about 3 less hp than an unbolted exhaust. i dont know exactly where you're coming from, but it seems to be obvious that you dont know much about the vtec engines and their aftermarket parts (not to be a diss or anything). but here's some words of wisdom, if someone that knows what they're talking about gives you advice or answers your question...be thankful and take it

 

Basically there are two main advantages, IMO.
The first is the quality. Its OEM, so you are assured that the parts will fit
and function flawlessly. Its really the same reason as why you would use an OEM
waterpump or timing belt over an aftermarket piece. The second advantage of
using R parts, is that for the most part, you will gain horsepower accross the board
without having to sacrifice much torque or lowend HP. If you go with some Jun III/
Toda C cams, Skunk2/Victor X intake mani, etc, you are pretty much assured of
getting a few more HP at the expense of lowend. There are a million dyno charts
such as the ones above which will agree with what ive said for the most part.

 

And just for the record,
the "modifications" done to the ITR exhaust are not all that amazing.
Ive done the same thing to pretty much every header ive put on my car,
but most were already welded on the outside.

 

first post i asked <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by NitrousDreamz &raquo;</TD></TR><TR><TD CLASS="quote"> the proven gains for using ITR parts on b16's such as cams, intake manifold, jdm exhaust manifold. is there advantages for using ITR over aftermarket?</TD></TR></TABLE> i didnt ask for proven gains on lsvtecs. thats great info you provided but not what i was asking about. if you cant provide *proven* gains and differances on a b16 like orginaly stated then let it go. i admit those are great dynos on a lsvtec. but i specifically stated a b16. thanks for all that info. i know some one here will understand what im asking for.

 

well...dont bother looking here anymore, find somewhere else

 

hahaha .. why you all defensive? haha .. why should i look somewhere else.. if you dont want to participate in the conversation then you dont have to. can anyone else offer any positive information on the topic?

 

All the positive information has really been exhausted already... its all there, I understand it and I doubt I'm the only one

 

i'm not being defense...i think its more or less you thats being unreasonable. when you ask for what kinda gains you might get on a b16, w/ ctr or itr cams...and someone shows a link to a b18c, or a b17...use your brain. if the b18c picked up 14 hp, expect the b16 to pick up a little less. you're never gonna find any dynos out there that contain exactly what you want to. and like mr saturn said...all the positive information is here, either take it...and start thinking about it, or look for it yourself. and i highly doubt anyone else is gonna help you

 

i am just tryin to conversate about a b16 with itr cams.. if you can dyno a built motor, a b17, a b18c i really honestly dont think that a b16 with itr cams and basic mods is unreasonable. I 100% understand what you are showing me but i am not looking to talk about a lsvtec with itr cams or a vtec head with itr valve srpings and itr cams. i understand that ITR cams have better power gains over b16 cams but i am interested in those average numbers you would be getting. i am not tryin to research the subject. i just want to talk about it. is a b16 with ITR cams really unreasonable? im sure theres alteast 20 ppl on this board that has ITR cams in a b16. i honestly dont think its unreasonable. theres no right or wrong im not debating that they are better or not. i agree with you, they are better .. but why and what kind of gains can we expect on the average. if you were goin to build a motor and drop 400 bills on some cams would you really say to yourself " well i know those cams were good on a lsvtec or a b18c with typeR valvesprings so ill just buy them and hope they work well with the b16" i know i wouldent.

 

nice comparison.. 4-1 header to 4-2-1. :S
