Ok. I took off my exhaust cuz it was illegal. I put my stock exhaust back on.

For my GO mods, now I have: AEM CAI, DC 4-1 Header, 2000 ITR Cams, Skunk2 Cam Gears, VAFC.

I don't have the ITR cams, Skunk2 Cam Gears, and the VAFC installed yet. But my question is: After I install all my parts and Dyno Tune it, How much wHP can I expect? What about 1/4?

 

it is allmost impossible to tell...just do it and find out
all cars are different. i really dont think anybody could give you a straight answer

 

I'm not asking for a straight answer. Just an estimate or a guess. That's all I'm asking. I'm totally lost and have no clue how much wHP i will have with this setup... Anyone?

 

then i would guess around 160 whp but that is just a guess

 

if you just drop it all in you'll have between 160 and 165 but with some tuning you can probaly get at least 170 or 175, although actually since you have it all restricted by a stock exhaust that is gonna hurt you bad so you can subtract at least 5-10 hp for that. go to http://www.geocities.com/dynocenter/home.html theyve got some similar setups

 

Alrighty. I'll be expecting around 170wHPish with this setup and tuning.

I want to get a Skunk2 IM also. I know that will give me a good amount of gain too. What else should I get for this setup??

 

With that Skunk2 IM....shouldn't you switch over to a ITR AEM-CAI? Will the GSR CAI be too restrictive?

 

CTR pistons, up the compresion

 

You can't even use the GSR intake, the throttle body on the stock GSR intake manifold sits considerably lower than the ITR/Skunk2 intake manifold. You won't really get much out of the skunk intake manifold unless you are running FI or a nice set of cams. Skunk actually designs their cams for use with their intake manifold, so you might be best off to get a package of their parts. The single runner intake manifold will kill your low end power, but give it all back up in the top of the rpm range.

 

With the S2 IM, I thought I DID need an ITR Intake, but my shop said they can modify it to make it fit.

As for the CTR pistons, will it give me noticable gains?

 

you think its worth losing low end to gain up Top?? I personally would like to have a nice Top end. Wouldn't mind sacrificing my low end, but if i lose TOO much power on the bottom, i would have to think bout it again...

 

I would just get a type r intake. It has a larger diameter to give more airflow, and is designed to fit that manifold. You will get a very noticeable gain by using CTR pistons, just be prepared to do lots of tuning to guard against detonation; your compression ratio will be around 12.3:1, which could be difficult to run on pump gas.

 

damn! 12.3:1?! Thats hella high. What other mods should i get other than CTR piston, or S2 IM...

 

USDM ITR pistons, JDM ITR pistons...jdm itr will put you at about 11.3:1, which is very streetable and will give you good power. US itr will put you about 10.8:1 or so. Coupled with ITR cams and a skunk2 IM should make some good power.

 

Do i need ITR Valves along with the ITR Pistons?

 

You don't need the valves.

 

I 2nd that, expect around 170-175hp. 1fastGSR had his car run 178 hp with '98 cams

 

and what does he run in the 1/4??

 

I don't know if he ever ran on the track before, but assuming it was a 2dr i'd expect it to get around 14.6.

 

14.6? hmm...


Well I ran a 14.8 with only I/H/E - I'll be installing ITR cams, Skunk2 Cam Gears, VAFC, and Dyno Tuning, and I should only expect to shave off 0.2 seconds? Damn.... I was expecting to hit low/mid 14's...

 

all depends on your motor. some motors put out more hp than otehr motors even. i dunno tune it. dyno it.

 

You ran a 14.89 with just those? I must say thats a very very decent time K maybe like 14.4 ish. But remember, its very hard to make a car half a second faster.

 

my friend kinda has the same set up on his 00 GSR. But he has the ctr intake cam and the itr exhaust cam. Also, he doesnt have the vafc, but he has a chipped ecu and has the full msd ignition set up. He also timed his car on the nitto street slicks at the Sacramento race way and pulled 14.25 ALL DAY, but he also knows how to drive his car good!

 

cool! I'll be driving extra good when I hit the track with my new setup. I'll try to get Low 14's...

 

My tires suck tho... i HATE these stock tires!
