DON'T DO THIS! Not unless you're planning on making 400Hp. Up until the 350HP mark, they make no noticeable gain in the top end and a VERY noticeable loss in the bottom end (assuming they're working). I've had my CA18 both ways, and I didn't like it as much w/o the butterflies. Before the oil filter failed and ruined my 8 port, I was going to pull the sub-manifold back out and put my other sub-manifold with the butterflies back in because it didn't gain me ANYTHING to remove them. I'm stuck with 4 port now though, so we'll see how it compares.Ron240sx wrote:... but i may just remove the butterflies from mine....
I've been running a SPEC stage 3+ for about 40K miles @ 300whp and never had a hiccup. I LOVE the light pedal pressure. I can drive my car around in city traffic all day and my leg never tires. I drove my friends KA powered S14 w/an ACT and it was so hard that I doubt you could drive it for more than 20 min w/o your leg starting to tire. Mine has never slipped eithercbh148 wrote:Hmm well I'm hoping my stage 3 pressure plate is a lot stronger. My friend said it's dual sprung.
That's good to hear (that you like your SPEC stage 3+ pressure plate). Perhaps worth mentioning is the fact that my pressure plate is just a stage 3, rather than a 3+. Hopefully this makes little to no difference.float_6969 wrote:I've been running a SPEC stage 3+ for about 40K miles @ 300whp and never had a hiccup. I LOVE the light pedal pressure.

Not to say that other ppl haven't had problems with SPEC, but they're a HUGE brand, and some failures/problems are to be expected. It's how the company deals with the problems that is the most important.




Don't worry man, I appreciate the critique/2nd point of view.float_6969 wrote:cbh148, if the new ACT disk is the same size as the used SPEC disk, then they MAY be right. IDK if you've ever looked at a disk after it's been broken in, but a fair amount of material comes off during the break in procedure. My concern would be that after break in, the disk would be too thin, which would cause the pressure plate not to put enough pressure on the disk, which would cause it to slip.
I don't KNOW that this would happen, I'm just speculating. I'd hate to hear that you got it all together and then it slips and you have to take it back apart. Maybe call ACT?
I don't want to come across like I think SPEC is better than ACT btw. I think they're both reputable companies. I only have experience with SPEC, and so that's all I can really speak about.
im burning chips but i wanna get a stand alone.float_6969 wrote:How are you tuning?
The spark blowout is on stock coils though, right?

Sounds like you've got your setup pretty well sorted out! Any particular reason you're sticking with a sidemount?silvios wrote:Well i have clocked up 1350kms on my CA.
Work is:
• Head sandblasted and cleaned
• block bored 40thou and honed
• Head machined
• block machined
• JE SRP forged pistons
• new piston rings
• new big and small end bearings
• new water pump
• new head bolts
• new Bosch timing belt kit
• new genuine Nissan oil pump
• Full durapro gasket kit
• new intake and exhaust and turbo gaskets
-STD ECU
I am running STD ECU and STD turbo as i bought a braided line kit for to put on a T25g, but they didnt fit, plus i didnt clock the turbo housing - so to get the car running i bolted the std turbo on.
I have just purchase an ARC side mount which i can install and then i will most likely boost the T25 to 12psi - 13psi MAX.
After that ill prob get a new fuel pump and O2 sensor (smart things first) then go new turbo (T28bb or even thinking GT2871), injectors(GTR injectors), and tune (nistune).
Hope to get around 200rwkw. Maybe more.
yes stock coils.float_6969 wrote:The spark blowout is on stock coils though, right?
