Could you guys post your setups:

All guys with 94-01 GSR's that have ITR cams installed.

Also, if you have dyno numbers that would be beneficial. I want to see what kind of power you guys are making.

If you have your 1/4 mile slips with the ITR cams that'd be nice too. Thanks.

Just wanted to see how you guys were running. Im hoping to hit 13's with these cams in my car....who has accomplished this?

 

With your huge list of mods, I would hav gone with bigger cams. Such as Toda's or Skunk2 stage 2. The itr cams with your setup should yield around 10-15 tuned properly.

I went with the ITR cams because I wanted the oem quality and a cam that is very good for the money. Im not out for a car with a rough idle and a car that won't be reliable at all times. The ITR cams are perfect for me and will put me into the 13's I believe and thats what I am after. I just can't wait to get everything installed and tuned.

 

I just bought some today. I will let you know.

 

I would think that with your current mods, especially the DPR stage VI head you would be in the 13's already.

Well since the car is running very rich and the vafc settings are way off then id assume thats the reason why im not running in the 13's. Thats why excellent tuning and these cam/cam gears are going to wake this car up.

 

i have the almost the same mods as you.
what ur missing is higher compression.
also consider stiffer valvetrain and higher redline.

i dont think u will have a problem getting 13's. low 13's may be harder but use some race fuel, wt. reduction, and practice that launch and shifting.

 

Stick: Thanks for the post.

the reason why the cams are going to free up quite a bit of horsepower (hoping for 10-15 whp after tuning) is because with my mods I need a higher redline/ecu program and I also need a bigger cam (yes i could go bigger then itr's but I don't want to as stated and reasoned above) and thats what the ITR cams is going to do for me. Greg (aka Cheetah) is going to be doing the dyno tuning/programing the ecu and redline. I just have to put everything together (cams/cam gears).

Damn you're GOOD you are the Human DYNO!

LOL No one can tell you what your car will do. You have to know what each component will do for your car before you mod it. Tunning is KEY probably more important than your components in some cases.
I guess if you want to make a clone of someone elses setup then oh well. All the numbers in the world and Dyno polts and advise will still not tell you what you can expect.
I have built two NEARLY identical engine with two different people and I am using the same general components for my setup. So far the other two are running quiet well but one is pushing about 20 Hp more than the other. The Only difference is the Spoon Rocker Armsand I seriously doubt that is where 20 hp is coming from. Just some food for thought

 

also consider bigger injectors and adj fuel pressure regulator. i would also get a fuel pressure gauge.

a good port/polish would help.

are u talking about cam gears giving 10-15 hp?? u would be lucky to get about 5-8 hp just from that.

greg can help u alot.

 

i don't know how much the cams made by themselves, but here's a dyno graph of how much power my car made with the cams in a GS-R with stock bottom end:



mods are: itr cams, skunk2 intake mani+gears( +3/-1), jg/edlebrock header, k&n drop in replacement, stock itr exhaust, aem fpr set to 51 psi, jdm itr ecu, and p&p. hope that helps you + good luck!

 

Thanks for the dyno graph ....nice numbers


Do ITR cams basically stop making power at 8250 where the stock itr redline is? Or would I be able to have a higher redline considering the mods I have to go with them?

Im sure ill find out at the dyno because ill be getting my ecu chipped there too, so im sure the graph will show when the power drops off. But I was just wondering.

 

thank you! but i gotta thank lawrence @ dynospot racing. he's the real reason behind the #'s...

i've seen ITR cams make power up to 8500. you can find many examples of this on http://www.importreview.com so i won't waste their bandwith by linking. i believe mugen makes their ecu compatable with stock itr cams and they have a redline /fuel limit cuttoff @ around 9000. hope that helps! good luck!

 

The itr cams are more streetable. Peak hp might be a bit higher on aftermarket cams but the itr cams have a wide powerband and start making power sooner. I think they're better for a street car.
Just out of curiosity, how are you upping the redline/tuning the a/f with the stock ecu? Custom chip maybe? Do itr cams make power above the stock redline?

I thought that the DPR head increased the compression significantly. Am I wrong?

I think what he means by raising the compression would be like a mugen headgasket, some higher compression pistons and so on. The more compression the more the naturally aspirtated engine loves purrying

 

first thing take your car to the dyno , see what works since you have the valvtrain i would get some skunk stage 1 or toda spec a , but see what the type r cams do , i didnt make anymore power after 8100 with the r cams but it all varys your setup is alot better than mine

 

i have :

94 gsr

itr cams(97 spec)
skunk2 intake manifold
dc 4-2-1 2 piece(jdm 4-1 in the mail)
full tanabe racing medallion cat-back
cold air intake
p28 ecu with a ih8ricerz chip (5600 vtec, about 8250 redline)
msd 8.5 mm wires

best run is a 15.6@92.5 mph with 2.5 60' time..

that's at bristol--where the nopi race wars were held a few weeks ago..and everyone said that it was one of the slowest tracks...so that doesn't help any..

just bought a b&m fuel pressure regulator. haven't put it on yet..thought about cam gears..but i'm not too familiar with tuning just yet..

 

well to get alot more out of your setup your definately going to want cam gears. should definately be your next mod. you will see great improvements just by tuning. especially with the itr cams ....see if you can get to a dyno and show us your numbers.

cam gears for you

 

If you dont' have the proper valvetrain, you shouldn't be revving past the current GSR redline...upgrade the valves if you want to do that.

And I don't know who suggested it up above, but someone said "race gas" as a recommendation to get into the 13s....he doesn't need race gas...race gas does not make you go any faster....it actually burns slower which will hurt your performance. Let's not give out bad info...

 

Definately upgrade your valvetrain if your reving at 8250. Once you tune the car and upgrade your valvetrain then you should see a lot better times...and get yourself to a track with normal timess you know what you run.

What are you putting down for WHP.....

 

I got a couple quick questions for you guys. I got a 95 GSR with bolt ons and a VAFC. I'm thinking of doing a Skunk2 stage 1 intake cam setup over the CTR intake cam setup. Is this the right way to go for makin more ponies with ITR valvetrain? The part I'm having trouble with, is choosing a good exhaust cam. How different are the CTR/ITR/GSR exhaust cams from each other...which should I use?

 

hey,

I have the ITR cams installed as well. (see setup below) car feels better but I desperately need a tune.....hope to get it done in the next few weeks.


great mod!

YV

.... I thought that the DPR heads (Stage 4+) had metal welded into the quench area to increase compression significantly. I know of a B16A powered DelSol that ran 13.9's with that DPR 6 head, stock cams, DC Header (2.25 collector), Greddy SP exhaust, Iceman int. with slicks. Seems like BS but I did confirm his setup.

 

i forgot to mention i did do the itr valve springs...not just move over the gsr intake springs..i went ahead and bought all new and sold all my old springs and retainers
