I'm currently looking at buying a 2004 that supposedly has a built 3v swapped in.
I'm confused on the intake that is currently on the motor. Any input is welcomed.
Thank you.

That is a 2V intake.
In 20 min or less you can pull a valve cover and check for 3 or 2 valves.
My money is on that being a 2V engine.

He said it's a aftermarket intake that is not as deep ,moves more air and will work on 3v and 2v??

No.
The intake port is so different that a 2V intake will not work on a 3V head.
It is possible that it is a 3V short block with 2V heads, but WTF would anyone do that?
They are both the same displacement,

Wow I can't thank you enough.
At this point I believe he may not even know what he has himself.
It's an 2004 and he claims it's got 18k in upgrades and is making 400+hp.
I test drove it and idle seems to stay really high for longer than it should, then it drops down to normal. It does run good but doesn't feel like 400 hp. In my opinion.

I don’t see $18k into that.

That’s a stockish 2V with a stock intake and an aftermarket plenum/throttle body. Those might be a set of pulllies. If it had cams, you’d hear it.

It’s probably making 270-280 crank HP. Closer to 300 if it had long tubes and h-pipe and good mufflers.

Looks like it has maxspeedingrods coil-overs which are $300 coil-overs. You can see the annodized red poking out in the strut tower. If they aren’t riding rough now, they will be.


I also see Corbeau seats (maybe $1k) a couple guyages, no radio, and a long ass shifter. I assume some exhaust work.


This is a $5-8k car unless it has lowish miles (under 80k) It looks clean but I’d have to junk those coil-overs right away.


Edit: does look like it’s an Accufab plenum. Someone stuck the stock plenum pony emblem on it, which is a good idea
