b16 or gsr head?

[redlightrandy]

i plan on doin an ls vtec in my 94 ls. i have a choice on wether to get a b16 head with a skunk 2 to intake manifold or a gsr head with gsr manifold. i want to do the one that will make the most power but also want the one that is good and reliable. let me know which to do.

b16 head with the skunk2 manifold. I am not a huge fan of the gsr manifold myself.

[babyrex22]

i gotta skunk 2 pro series manifold for sale if ur gonna go wit the b16
lmk

and gl wit the build mine just got done yesterday

[cashflow]

if u go gsr WITH the skunk2 ull get more power thats what im doing

[my99ctr]

if u go gsr WITH the skunk2 ull get more power thats what im doing

actually you will lose about 10 foot pounds of torque (felt like spelling it out) but you will gain a few hp on the top end i used to have a 99 gsr had a baseline done put ctr cams in and went back to the dyno aft ctr cams i made 198. something than I 2 went out and got a skunk 2 in mani lost 10 torque and gained a few hp on the top end so i went back to the stock gsr intake manifold

[redlightrandy]

i dont really want to lose to much torque. might just do the b16 head and skunk mani for more air flow.

i would go with the B16 head. later down the road you could do a mild PnP and R valve train and basicly have an R head. thats the way i am going. but every one has there own opinions!

[Lilrob]

ide go gsr

[92hndahatch]

b16 im pretty sure you will get higher compression and the skunk2 mani's are nice thats what i have on my b16 and i have plenty of torque

[2000si]

b16 head because im not a fan of the butterfly design on the gsr

[Type - O]

b16, better factory flow and slightly higher compression i think

[Wholesaler]

b16, better factory flow and slightly higher compression i think

only flows a few more cfm and is less compression then a gsr

gsr head, betteR just for the fact you can get better intake manifolds for it

[Type - O]

why cant you use GSR manifolds on a B16? i thought all B series things were basically interchangeable

[Wholesaler]

nope

[Type - O]

oh

[Lilrob]

thats wat i thought too lol

[urmyboyblue21]

from my own experience the only difference as far as bolt ons is the gsr intake bolt pattern is different everything else will work i used my gsr cams and exhaust on my 99 si head and an edelbrock victor intake worked beautifully till i got jacked for it all dam haters

[92hndahatch]

only flows a few more cfm and is less compression then a gsr

gsr head, betteR just for the fact you can get better intake manifolds for it

wont a skunk2 mainfold flow better then a gsr manifold?
otherwise what would be the point of buying an aftermarket mani. i know tons of people with gsrs and get skunk2 intake mani's and i thought that the b16 head had higher compression then the gsr head. if it doesnt thenmy friend putting the jdm b16 head on his b18c1 was kind of pointless

A skunk 2 manifold will flow better than a GSR yeah, but the issue is the GSR's head flow rate ontop of the cam profile for GSR's.

Stock for stock a B16A head flows better than a GSR head from barely opening to about half way to TDC of the valve, same is said for the way back down. The reason the GSR head flows better is because the nature of the GSR's cams. Which have a big duration on them when compared to the other B series motors.

So in order to take advantage of that peaky flow rate you're going to need a long duration cam, which runs you the risk of losing some pressure in the cylinder. simply because the valve will be open so much longer than normal.
Alot more to it than just slapping on a new IM and calling it a day. Especially if you're not stuck with a Freebie option.

If you're gonna spend $ on either route, which i'm guessing you do. Go with the 16...I mean you can't go wrong with a free AM manifold.
Ontop of that a PnP gets you a type R head so who can argue.

Oh and are you going for a NA build or boost build? Cause if you're boosting i'd take the straight runners of the JG over the S2

[redlightrandy]

i'm goin all motor cause it will be way cheaper in gas cause the need for bigger injectors and that arn't as high in a na set up.

[Wrist Watch]

Well either application, I would suggest the B16 head simply because it's a tried and true cast (ITR FTW).

When you break it down into the diff CFM flown by each head, the margins are so minuscule especially when dealing with what i'm assuming isn't going to be some hardcore all-motor build.

So you won't notice any serve negatives out of the b16 when talking about the valve duration, and it will probably only help the peakiness the engine itself lacks as a whole Considering the B18 is a under-squared bottom end adding a B16 head would help it with the revs it can't quite get like a B16 can. But yeah...Get a nice PnP job done on the head get yourself a proper ITR head (if you have the spare change..if not it's no biggie) some nice cams and that IM and you'll be ready for your N/Astiness.

id go with the gsr head i have it on mines and its fast i beat my friends and he's got a b-16 head both in teggys

[redlightrandy]

his "CHECK DRIVER LIGHT" was on thats why. lol

[Wrist Watch]

Lol..hahaha someone needs a tach with a speaker that just yells out "SHIFT NOW!!!! RAAAAAAHHH"

[redlightrandy]

lmao! ya
