Im torn on what to Do

I saw this and now im torn on what to do i wanted to get 1.9 rr and a 2.5 downpipe but now i am wondering if id get more gains with a High Velocity Throttle Body for the L36 and a HV3 High velocity intake insert but im not sure of the options id need to get from zzp and keep in mind all i have is a air intake so which decision is best and would they cause more problems down the road?
Thanks,
Bobby
 


Personally, I would start with the DP, then the rockers. I would imagine those two mods would show the greatest improvement.
 
I would also have to agree. Keep in mind you got to get rid of the air you are sucking in effectively before you add more. So the down pipe would help that some, but of course the 1.9 rr's are going to add a bit more air to get rid of as well as a TB and HV3.
 
For a GT stock exhaust is good enough to flow for 1.9"s.
Yes DP will help.
I would do rockers hand down first.

Now is your ? rockers and dp VS. TB and intake?
 


I would do things in this order:

DP
TB
Rockers
HV3

Somewhere in there you might want to add a Powerlog since the stock front manifold is quite restrictive. I'd do it before the TB or rockers.
 
How much HP's would all that put out and how much money is the powerlog because a shop is going to want an arm and a leg for everything
 


The thing is with gas prices the way they are I cant afford putting fine tune fuel in my GP so id do....
DP
Rockers (with 1.9's dont have I to upgrade the valvesprings and timing chain/gears.)
then
HV3

Assuming you already have a cold air intake, your next mod should absolutely be a downpipe, preferably a 2.5" example as you have been talking about.

Next, do NOT go with the 1.9's. They are far from optimal for the L36. They provide a much narrower powerband than the ER rockers that ZZP sells, which use a specific split ratio for the non-supercharged motor. With those rockers you need 90# or 105# springs on the intake side ONLY. Optionally you can choose to use aftermarket pushrods, although they are not required.

After that the best next modification will be an aftermarket PCM, be it through your own tuning software or from one of the vendors. The increased operating range the downpipe and rockers provide will be worthless without raised shift points. If you use an off-the-shelf PCM I would recommend getting in touch with Will @ Overkill.

Just with those three mods plus and intake I ran a 14.9 @ 92...not bad for a L36.
 
Well with looking around the forum i think ill do..
-2.5 dp (magflo cat + U-bend delete)
-PEM
-Rockers (ER or 1.9rr have no idea)
-Aftermarket PCM (overkill)
-HV3

NOT AT THE SAME TIME

then a TB but i really dont know much about this mod ill have to do some research or someone can step + isnt primium feul needed?

My only problem is I DONT want to put primium fuel in my car im losing my mind with these ******* prices and with a PCM its recomended but not neaded from what i understand and wouldnt a tune be more expensive?
