Going with a 2.55/9.55 pulley combo, stage 2.5 cam kit, cai, longtubes x pipe, ported snout, 93 tune (E85 is not an option) injectors, dw300c drop in pumps, ice tank and lpe pump.

I got 3 choices can't do both, Ported LSA heads or Ported blower OR meth injection..

My bigger concern with the options here are cooling hence the meth and as much reliability as possible.

Each option is gonna cost me around the same so what would y'all do? A6 Daily driver until i buy a winter beater. Thanks!!

You better do the meth first, and save your money for the others.

Your pulley choice will make power until the heat kills the timing, which won't take long, so you need the meth for cooling and octane.

Furthermore, you really should do post boost meth, so you get the maximum benefit, and also so you don't prematurely hurt the blower as meth can wipe out the bearings, and will remove the rotor coating, though the coating is less of an issue.

IMO- Meth is the cheapest option and directly addresses cooling especially if you are doing post-boost in the lid. A ported blower is going to raise "boost." Not sure how heads will affect boost/cooling at the point you're at.

Heads will lower boost a little and gain good power with the cam, but he will still fight heat and therefore octane.

E85 would help with the octane, but it's not an option.

I wanted to do 2.55/9.1 but for some reason they insisted on a 9.55 lower. So the only point for the meth would be for cooling... but I don't want to cause any issues. I see where people say the ported heads help with lowering boost levels and hp obviously I don't want a tremendous amount of heat fighting..... So definitely the meth post boost is the best option?

If meth has a possibility of eating the bearings up then why do that if I can do the heads and possibly do any type of help with the heat and make power? I don't wanna blow up my 4k mile ctsv coupe

You're going to be making a LOT of heat, and need a LOT of cooling (or octane). Meth is the obvious choice. As in, it's not even close if you're worried about a budget.

When it is time to freshen up lifters, then do the heads. Problem with head swaps is all the other stuff you want to do while you're there - and that blows out the budget easily by a factor of three.

A ported supercharger isn't even in this discussion - that's one of those "just because" mods when you want a few extra ponies.

Post boost meth wont hurt the bearings, just make sure you use check valves.

Heads are always a very good option, but you will get a lot of heat from your pulley combo.

Ported blowers are a good power addition, but it will add more heat as it creates more boost.

If you did all three, you would see probably 120 hp gain.

What meth kit are you comparing the cost as the same as heads or blower? Ported blower is a definite no until you get heads and meth on the car with that pulley combo. It's your car, I would tell the shop you insist on a 9.1 lower ring. That scares me a bit when shops insist on things that hurt the car more than they help it with your combo.

The meth kit they said would run 1400 installed... which I feel is high. But whatever. The heads would be 1400 ported and setup everything done correct.

Looks like I'll do the meth post boost and the check valves?

$1400 for heads makes me think they forgot to include labor - and that probably doesn't include lifters or pushrods but maybe that's the one shop that's cheap on heads and expensive on meth.

Ouch. Buy an Aquamist system and install it yourself.

I'd pulley down and do the heads. Lose a bit of boost but make up for it with better midrange power and less heat issue.

If you asked for a 9.1 why did they do a 9.55 and now you're fighting heat?

Well the install isn't done yet.... I'm not crazy about the idea of meth but I'm not sure. I haven't even discussed power levels or goals. Just told them I wanted a good build... guess they figure that's the way to do it. Idk lol. All I do know is if the meth is gonna be the only way I guess I'll do the meth. Figured ported heads would be cooler but whatever.. gotta do a tire setup to. Damn this is worse than crack, gets expensive quick

Hi. I'm doing XXXX. I have these 3 options. What should I do?

Entire internet: bad idea. Do this.

Well I'm gonna do it my way anyway...

Did I miss anything?

Nah haha I'm doing the meth. Just confused as to why they would recommend the 9.55 is it's doomed to blow my shit up

Do less pulley AND meth?
