How much did they cost you? And please be sure to post the results after the install
I want them too, but I only have the $$ for cams. Plus, cams are supposedly good for 20HP, and cost 500bucks. Heads are what; $2500 dollars for 35HP? Is 2500 dollars worth 15HP more? I think not
Unless heads add 35HP on top of 20 from cams, but I seriously doubt that is true. To be honest with you I don't even believe cams add 20HP.

Cams and springs ran me $1100, but I get $400 back when I send them my old cams. (core charge)

They are freakin awesome but I'm going to refrain from writing a full review because I'm getting a misfire issue right now. I want to see what's causing the misfire first.

Holy Crap! $700 for cams! If by any chance you can get to the dyno, please fill us in.

Has anyone considered calling/trying Delta Camshaft?
http://www.deltacam.com/

They did both of my cams (the stock ones) on my XT6 for $150.

darioc - good choice too bad you couldn't get their matching short block!

powerlabs - you need to try to look beyond peak power figures. The point in doing the heads is to allow gains across the entire rpm, and allow the cams to breath easier at higher rpms. Not to mention, an efficiently designed combustion chamber and headwork will allow for better fuel mileage (when you're not lead-footed ofcourse )

Kevin Thomas - FYI that's cams & springs that obyone got

Jup...Cams were $400 ($100 less than Cobb) but the springs, which are recommended that you get as well, are $300.

MWIC is having a dyno day in the middle of May. I'll be doine some baseline runs to see how much effect my meddling...I mean Modding has done.

i got the cylinder stage 2 package. it was $2669. it includes the stage 2 street/rally cams, titanium retainers, springs, and the worked heads. the difference between the stage 1 and stage 2 heads is the $400 combustion chamber work that they do. keith told me that i really should do that because i would feel the difference.

im going to try to get my car dyno before and after and post up the results are their website. we'll see. i have a full catless exhaust with headers, a cai, and an underdriven pulley as far as performance mods go. it will be interesting to see the gains on top of that!

If you have the stage 2 cams you will likely have to live with it. My Cobb cams have "misfires" on all 4 clinders acording to the ECU.

TWE and COBB stages are different. TWE Stage one is Turbo use, Stage II is street use.

Yea. I know that they are "different".

No. Stage 1 is on their website, read it again. It is nearly the identical description to the Cobb cam.

Stage 1 is very simular to Cobb's mild cam (street cam).

THe Stage 2 cam is very simular to Cobbs Spicy cam (Club Racer). More lift, less duration. TWE is going to idle a bit better , Cobbs are going to rip a little harder in extreme high end. Posibly beyond the stock redline.

You can use stock valvesprings with Cobb spicy cams with the stock redline. TWE since it has higher lift, you are *highly encouraged* to purchase springs to eliminate the posibility of spring bind.

So again. If you have misfires on all 4 cylinders using the stage 2 cams, you will likely have to live with it. A lightweight flywheel makes it worse.

I'm not going to argue with you. Argue with Keith about it, I have discussed the stage 2 cams at length with him.

cheeRS,

Greg

*after re-reading TWE's site*

Ah CRAP, I got boned!

Luckly, I took my RS in for emissions testing as soon as I had the Cams installed and it passed with flying colors.

BTW...I've been talking to Keith (Croucher from TWE) about the misfire issue and he said it's not supposed to do that. At this point, I'm betting my Magnecore wires are poping out again, but I haven't had a chance to check them out.

[edit] No wait, I didn't get boned.

The Stage II cams are for SOHC engines. The Stage I's are for DOHC engines or at least that's the impression it gives on their site.

Also, the Stage I's are almost twice as expensive as the Stage II's. I'm assuming it's due to that you are getting 4 cams instead of 2.

They make all the cams for SOHC and DOHC, even though they are not listed on the site. The next time you talk to Keith as them what they can do, not just questions about what is on their site. THey have all stages for both heads. WIth the same idea behind each stage.

They also have a World Challange grind for the nuts out there (or actual race teams). They are builiding headers that are not listed on their site. You can have them build any exhaust configuration that you want, on any of four header designs. They will basically do just about anything that you have the money for that are not on the site. It might just take a little time.

Have you seen that on the site?

cheeRS,

Greg

Well thats something that SHOULD be on their site. But in either case, I'm like 90% sure it was caused by my Magnecore wires. I just replaced the plus on my car (why not? Already had the damn thing apart to mess with the wires.) and reinstalled the wires. This time, I was able to get the wires to stay put. I figured out how to fix them. But that's for another thread. (Also reset the ECU) 2 days and 20 miles later, my CEL has not returned. On top of that, the car seems to have found some balls it didn't have before.
