DERICKS...plan v.1

current setup:
mugen header
intake
blacktrax electronic cut out system

Ok so guys I recently just sold my Crower Stage 2s because I didnt want to mess to much with the head as far as upgrading the valvetrain.. sooo



I am planning on selling my moogen header and going back to stock header



With the money from the moogen header, I am planning on buying a set of Type S cams w/o upgrading the valvetrain, and buying a phearable p28 ECU and get crome tuned.



The only problem is that I'm wondering if my stock header with a ECS (open header system) will be restricting or not. If its not restricting I think this will be a good setup because I will be all good tuned and ready!

Tell me what yall losers think about the header restriction

Type-S cams have more lift than the Crower stage 2's.... back to the drawing board.

Yeah I see that, but isnt it safe up to redline?

edit: after looking it up, many people said running on stock valvetrain with Type S is fine

so does anyone approve of my plan and eliminating my mugen header for stock with ECS? My exhaust flow will probably still be excellent considering it will be open header, it will have more than enough exhaust flow out, right?

serious answers please

people with open header have shown to lose power over a good exhaust system.

its all about having the right amount of backpressure, it acts like a siphon (sp?) and pulls the exhaust gas out instead of being pushed out.

also one of the reasons the type-S cams were made for the type-S is because it allowed the car to benefit more from having 11:1 compression.

going half-half isnt really a good idea, it will leave you disapointed. those cams and expecially crower stage 2's will LOVE higher compression so type-S pistons should be in your drawing board. (or other pistons if you plan on resleeving).

then again, your going back to stock header so everything i just said was a bit pointless without a good flowing header.

Isnt the SH header a good enough header for flow anyways as long as I have open header anyways? I mean the amount of exhaust flowing out of the header when the ECS is flipped open is so much that the header piping size is probably almost obsolete. And since the ECS with the mugen header is actually killing all my back pressure, the stock header will probably give me that extra backpressure that I need back.

u dont want back pressure. You want exhaust velocity.

Honestly if you're going to sell your Mugen header you would gain more power getting an SMSP, Hytech, or RMF header and keeping your stock cams along with the tuning w/ the P28 ala Crome.

This setup would be superior to a stock header and Type-S cam setup with p28 crome.

Get Neptuned by Andy Chan.

Crome is an inaccurate tuning solution at best. Also, unless you plan on getting a non IAB manifold, you need a p72 to keep that working.
Finally, if you have a type SH, the only solution available to keep the ATTS working is Greddy Emanage.

So your saying Type S Cams ARE better than Skunk2 Cams? So dont waste money on Skunk 2 and purchase Type S? Where the hell can you get type S cams anyway

That makes no sense... you're not doing anything that will outweigh the fact that you'd be carrying all that dead weight.

I understand that, but IMO the ramp speeds with the Type-S cams are higher than the Crower's and the lift from the Type-S is more than the Crower's. With less valvespring rate it's just asking for more problems vs the Crower's. It's not only about lift, but you'd only find me installing a set of Crower's with stock valvetrain. Though regardless I'd at least swap out the exhaust set to a stock intake valve spring set if I was to install a set.

the type S cams have a shorter duration than the crower2's which means they won't be able to move as much air in the higher rpms.

my suggestion to you... lets swap heads+cash and you will be all good to go

basicly - whats the point of spending money to go faster when you are being held back with useless items.
