Doing some maintenance on my 01 GSR and figured I would put some new cams in. I was thinking the Skunk2 tuner 1's. The motor will remain stock-ish. I may throw a small snail or Jackson supercharger on at a later date... Will the tuner 1's be my best bet for a stock GSR with simple bolt ons? Is there a better choice?

How it sits now:

01 GSR
ITR Intake arm
68mm throttle body
Skunk2 IM
4-1 header
2.5" cat back
Hondata S300

Thanks

 

yea tuner 1's will work good with basics bolt on's, witch cams are better it really comes down to what you want to do with your car, auto x, drag, etc.. ,

 

Stock valvetrain? Overall goals?

 

I may upgrade the valvetrain. Stock block. Stock compression. No headwork. No porting.

I just want fun, reliable car. I'll probably autox it and do track days. That's about it. Nothing serious. Like I said, I may throw a small snail on it. No more than 275whp max. Just want insant power. Or I may go the Jackson Supercharger route. Any sort of boosting wont happen for at least another year. I have way too much work to do on the monster d16 del sol build. Until then, just looking for a little extra go.

 

Well, you won't find a JRSC in one piece anymore (not new with all the brackets and such, anyway.). autox , won't require much considering you're only in 2nd and maybe 3rd gear depending upon the cone structure..

For circuit (road race), the Tuner 1s will be fine, and can still work with a small turbocharger setup.

 

I've got Blox A's on a stock B18C1 and they are fine. It is only street tuned so I cannot say how much power they make over stock but they work on 10:1. Tuner 1s should be "drop in" but I would advise stiffer valve springs.

 

I dont think a Tuner1/BloxA should even be considered. You'll be more happier with a powerband/torque in low/midrange from a bigger primary type camshaft. Look at least into some type of Stage 2 camshaft.

Run nitrous, over a root style blower. My opinion.

 

Pro 1's came to mind for me...

 

Why? Don't the stage 2's do better with higher compression? I am not building this motor at all except supporting valvetrain for potential cams...

No way am I ever running nitrous.

 

Again, I thought these cams will not perform well with stock GSR compression?

 

Says who?

Compression is ONLY 1 part of the equation.

Tuner 2's in stock GSR's kick ***, just have no bottom end. The pro 1's won't peak as much, but the mids will be much stronger. Pro 2's are a different story

 

Another thought is to call Web and see what they can come up with for me.

 

I agree with a lot that's been said. With stock gearing run the tuner 1's or the 2's. You just have to choose what trade off you want to make.

I have stock block gsr and run the toda b's due to my gearing great setup.

 

Stock GSR compression like stated is one tenth the equation.

I've done a lot of tunings on stock itrs, Stock GSRs, even stock b16's with mild to bigger camshafts, and they work great, don't be mislead by what you read, rather what others have in real world experience.

You seem to be looking towards what a pro1/Stage2 type camshaft will get you, I sent you a PM.

 

Why wouldn't you run nitrous?

 

Nitrous filling stations are few and far-between lately. Plus, I wouldn't like depending upon "the bottle" just to have fun, when a blower will let me have fun any time I want.

 

Nitrous is not my fav. Trying to regulate bottle pressure, refilling, its like a temporary fix. I would rather go with a supercharger, turbo setup where you don't have to worry about heating and pressure to keep stuff consistent. And forget about trying to get it filled in a pinch. Way worse than trying to find e85. Drag setup only when trying to spool your oversized turbo. I would look for cams with a smooth low to high cam transition, unless you need to pass emissions. Pro1's or others.

post #33 is a graph of wat i did way back

buddyclub3 has 250@0.050 dur. so its close to s2s1 or pro1

its a usdm itr but should be close to ur gsr, it dynoed with a filter
and full exhaust... no velocity stack and pipe extension to tweak results

just how it runs on the street.. HTH

 

it also used ITR valvetrain.. but an upgrade would def be safer

 

Id advise against any camshaft upgrade untile valvetrain is upgraded. If you go this route, and the head is to be removed, you can go with a thinner HG, and mill the head .010. Maybe even go with flat valves at that point. Otherwise, I really like buddy club spec 3+ on a stock gsr w/ valvetrain upgrade, or like others have mentioned, S2 tuner stage 1's.

 

BC3 > Tuner 1s

Tuner 1s are small... they are carb legal in CA, that should tell you something.

 

i made good power on tuner 2 and crower/supertech valve train for a year on a very similar setup before i dropped a valve in cyl #4 last week. im 99% sure dropped valve is due to installation error not a defect in the parts used.
