VAC motorsports heads

[8psi//E36]

I was just browsing their site, happening to come across their stage 1 - 3 heads. I'm sure I would spend as much as they're worth rebuilding / modding my current heads more. Just curious to anyone's thoughts on these?

They're pricey, but as I said I probably would spend as much as they're worth, maybe more considering if I had my heads re-conditioned and then modded, so it's 50 / 50.

The stage 1 head pricelist (for those actually listed) is as follows. You would have to call for any other year / model engine.

M42 Stage 1 Performance Cylinder Head
#VAC-S1PCH-M42 $849.95
M50 Stage 1 Performance Cylinder Head
#VAC-S1PCH-M50 $1249.95
M60 Stage 1 Performance Cylinder Head
#VAC-S1PCH-M60 $1799.95
S14 Stage 1 Performance Cylinder Head
#VAC-S1PCH-S14 $849.95
S38 Stage 1 Performance Cylinder Head
#VAC-S1PCH-S38 $1249.95

They seem pretty complete. Everything would be brand new since they're pre-reconditioned before purchasing - which is why I could actually rationalize purchasing them.

The stage 3 heads pricelist is as listed (with the exception of certain year / model motors, in which case you would have to call). These include titanium valve springs and retainers as stated.

M42 Stage 3 Performance Cylinder Head
#VAC-S3PCH-M42 $2399.95 list $2599.95
M50 Stage 3 Performance Cylinder Head
#VAC-S3PCH-M50 $3499.95 list $3699.95
M60 Stage 3 Performance Cylinder Head
#VAC-S3PCH-M60 $4699.95 list $4999.95
S14 Stage 3 Performance Cylinder Head
#VAC-S3PCH-S14 $2499.95 list $2599.95
S38 Stage 3 Performance Cylinder Head
#VAC-S3PCH-S38 $3499.95 list $3649

Again, this merely peaked my interest just because I happened to come across it.

I think this would be more appropriate in the FI section. However, to answer your question, the stock heads already have a high flow in comparison to how much you'll pay for a redone head. You'll pay a lot for not a lot of difference. However, if you are forced induction, you will notice a bigger difference, but again it's a thing of performance to dollar spent.

You could also contact this guy: http://www.dtmpower.net/forum/showth...ht=port+polish

Now if you got it done at that price, then it would be extremely benificial. (My buddy also has some nice prices too.....)

You are correct and then some.The stock heads flow excellent even for FI.The cost/benefit is not worth it UNLESS you just like to tell everyone you have 'special' heads.

Does your buddy who modifys those head do BMW's though? I looked around and didnt see anything about the beutiful bimmer on the page, will he do custom work? and If he hasn't done it before, can we really trust him?

Dont think you would need the Stg 3 head w/ FI...but....I am having VAC do a Stage 3 head for one my E30 M3s and I think that while it is expensive, it will be worth it in the end.....I hate paying that much money, but at the same time I'm not making the mistake of trying to get it done cheaper by someone who doesnt have the experience w/ S14s.......I'm just trying to do it right the first time.

[Jimmyz2]

Yes,you are right.IF you are going to do race heads VAC is the way to go.

Didn't I basicaly say what you said? If I didn't, I meant what you said.

Either that, or it's beneficial if your building extremely high compression, high reving engines. Oh and if you have 20 + thousand to spend.

I've talked to him about it, and thing is, it's the same thing as a 4 cylinder, but just 2 more longer. I'm trying to find someone who will donate or send one to him for bench flow testing to see what areas he can improve on.

The reason you see all neon engine's is because that's where he started in. His car that he tuned was a neon R/T, and he ventured into it that way. Next he had his own business and has many happy customers. This guy lived with my family for a year and a half, and he is a very close friend. You all might frown upon "Neons" and "how ugly they are" or what have you, but regardless of your opinion, still legitimetly tunes neon engines the same way you would a big race V8.

If you all arent in a hurry, I have an M52 engine I will be rebuilding in a few months, and I will rebuild my M50 for test purposes. At that point, we may have some BMW people having experience with him.

Or you could just e-mail him

They are great heads, All though I could do it for cheaper with just as good if not better quality.

ex: I will do a m42 head the same as thier stg2 with custom ground cams for the price of their stg2 ($1300)
