NOT LS/VTEC

i have searched and searched and have found nothing on this topic...ive found ls/vtec and gsr head on b16 block, but nothing on b16head/GSRblock.

i really just need to know if, for an all motor build, this would be a good idea, will it lower/raise my compression, will it offer more/less hp/tq, would it more beneficial if boosted, is it a direct swap or is there a lot of bs involved.

head is coming with a edelbrock performerX intake manifold.
so theres no need to tell me that my gsr mani wont fit, i know that already.

thanks in advance for any and all advice

its called a poor mans type r cuz its got the same head casting as type r and gsr and type r bottom end are the same. some say that it flows better than a gsr head.

no machining needs to be done. it will lower compression.

 

some call it a poor mans type R but it's not that. The type R and GSR bottom ends are not the same, the main difference is the pistons which are responsible for a .6 increase in compression compared to the GSR pistons. For street performance the GSR head is considered to have many advantages when compared to the b16a head. Both will work obviously and both will perform well if ported properly. If you bolt that head on your GSR block it will lose some compression and should be less powerful than the GSR head. I personally wouldn't change the head unless I had some big plans for the bottom end.

 

thanks for the info...

i was mostly concerned about the compression, the head is actually built and port&polished i know there is going to be at least some increase in hp/tq and being that its built, it will support much higher revs. it has complete supertech valvetrain(titanium valves and retainers and dual valve springs).
any idea on how much of an increase in power do you think there would be?

 

You might be able to see some performance increase....esp if you go ahead and swap in some higher comp pistons.

The headwork might let you see more of the potential from a more radical cam. If you're just talking about putting on the head w/ no other changes, I don't think you'd see much benefit.

If you're planning on raising the compression, etc, it will definitely benefit you.

Another thing you may not have considered.....you'll have to pick up a new intake manifild b/c the one from the GSR won't bolt up.

My advice would be to wait until you're ready to put a whole package together

 

the head comes with a jg performance intake manifold already. he wont have to worry about that.

just for the hell of it, i was reading a honda tuning article just now and it was the issue that featured the owner of endyne building an all motor, 300 hp, daily driven b-series motor. he chose to go with the gsr head because of its flow potential. just food for thought.

 

i guess i should have mentioned that i aleady have buddy club stage 3 cams so there wouldnt be stock gsr or b16 cams in the head..

what was the cover page of that ht mag? i should have that one but i'd rather search through covers rather than read through all the subtitles to find the article.

and thanks for the input

 

FYI, a b16 and GSR head flow basically the same and have similar flow potential. I can assure you that the GSR head was selected for something(s) other than "flow potential".

 

Its not even a snack for thought really. Like 00Red_SiR mentioned, their pretty even reguarding flow. After re-reading that article in Honda Tuning Larry Widmer didnt exactly quote the GSR as having greater flow potential in those words. More so what was said was, with each head both having some aggressive valvework the GSR has shown to make slightly more high rpm power (according to his statement).

He mostly commented on his prefference for the GSR port design and combustion chamber characteristics vs the B16, but he also mentioned that once he finds something he likes about one head he finds something else about the other to change his mind.

Here's a good comparison,

 

geez. i thought i was brutal.

 

i second that. he said one month he likes a b16 head, then the next he finds some thing new with a gsr head and vice versa

 

Right, I wasnt trying to quote everything in his exact words otherwise I should have just posted the article. I was trying to summerize or rephrase what was said.

 

Yeah....honestly, what someone can take from this is: USE WHAT YOUR BUILDER OR HEADPORTER LIKES.

I mean, when do you get the best meal? You give the chef a parameter, and turn him loose. Don't try to micromanage the guy....you'll thank yourself. Sure...bounce ideas off each other...but I usually defer to the experienced opinion. And it's just that....an opinion.

 

My apology. My first post does come off sounding long and e-blabberated. This might sound silly or stupid, but I actually made my initial post mearly as a means of bumping my post count past my 666th post. Call me superstitious
