Search ownz you my friend. And yes, the process will be basically the same for any of the vtec heads. I personally say go w/ a b16 head... slightly more flow than a gsr... and alot less money than the hype R.


and you'll get even more results if you search lsvtec, ls/vtec etc etc. They're the same damn thing w/ a slightly larger bore.

 

But a Type R head will flow better than both B16 and B18C right?

yes.

 

im not exactly sure with a b20 but it should involve moving some dowels and running a few oil lines. check in the all motor section.

 

Yes as with the LS/VTEC conversion to...dowels need to be moved and oil lines ran....im just wondering about the tranny..b/c im going to need LSD bad....(serious power)

Yes. But IMO unless you get a great price on a complete head, it's not worth the extra money (usually). The hype R is basically a b16 w/ a slight port&polish... and some very nice cams, IM etc . hence the 'complete'

You can just as easily buy a bare b16 head, and use the money saved to build a head that will exceed a hype Rs and probably still have money left over. just my opinion. this argument has been beat to death...

 

I have compared a b16a2 head and a 01 R head side by side and as far as the ports go the type are are alittle cleaner with less casting flash. The mild and port and polish is extremely mild at that. If you do a street port and polish you will have better flowing ports then the R. Of course you will need some cams and valve train to take advantage of the port and polish. Good luck.

 

Get a golden eagle vtec conversion kit. It is by far the easiest way to do it. Also you will have to get a VTEC ecu for the OBD year of your car. You will also need to run some wires for the VTEC solenoid and pressure swicth.

i dissagree with u saying using a b16 head. i have seen about 10-15 b20vtec swaps leave our shop this year and most of the time the ones with the gsr heads leave with better 1/4 mi and power results. besides gsr yeilds more compression than a b16 head(more of a squared chamber to the b16/itr's rounder oval chambers). hence more torque and power(ask dave from headgames motorworks he'll tell u gsr head is the **** )

-as for putting a b20vtec together i &lt;3 the golden eagle lsvtec conversion kit makes life alot easier.

-but i would suggest getting the valve reliefs shaved slightly just because on a ls head compared to a vtec head the valves are larger on a vtec head which is the reason why if u take apart a stock lsvtec or b20vtec u might be able to see the valve/piston slap. also a new waterpump and a vtec oilpump and of course timing belt and tensioner. also aebs or golden eagle headstuds work well also always good to have aftermarket headbolts on there.

 

i ran a b20 vtec stock b20b bottom end and stock gsr head and cams with some bolt ons. i made 180whp and 138tq

Yeah, see this is what I mean by the argument has been beat to death. If you browse through the ls/b20vtec threads damn-near every thread ends in this very same discussion. everyone has there own opinion... In regards to the ls/b20vtec discussion, I'm merely a bench-racer or spectator... i have a few friends w/ them, but never built any myself.

Theres no quetion, I will build one eventually... so I've done alot of reading (which i realize means little to nothing). From what I can come-up w/ the gsr head in stock/slightly-built form is a better decision b/c of the compression, secondary runners add mid-range blah blah blah. However the b16 head has more overall potential. If you plan to do a serious build, the compression-argument goes out the door, as well as the IM/valves etc. Also most of the hype-R head-parts swap-over w/ little to no work. This response has already gotten longer than intended, so Im going stop... this isn't meant to be an argument, more-over a discussion. this is just my opinion from what I've gathered over the years.

truth be told, if i could find a gsr head for a good price... id swoop it up in a heart beat. I'm really not that picky..

i guess i have the &lt;3 for the gsr head. right now i finding a gsr head in good condition i see people selling them for ranges of 500-600 where i can get a b16 head for 400-450 all day. again its just the demand of them i guess.
as far as parts swapping over the most key important parts such as the TB, springs retainers, cams all swap over to any b series head with lil work needed. remember a b series is a b series. btu then again maybe its my own opinion lol.

wow no ish. Its the friggin opposite here, and i hate it. the b16 head is so over-hyped around here it's like twice the price of a gsr.
i should have you buy me one and ship it to me jk

your right about most of the parts swapping over.. but you left out the most important one the Intake Mani. The gsr has all that 2ndary butterfly crap going-on... it's good to an extent, but passed 200-250 it becomes restricive. And in-order the swap out the IM... you'll need to get a chipped ecu. A new IM and an ecu is just added cost

the itr intake manifold id rather replace with a aebs or skunk2 (which both companies make terrific intake manifolds for the gsr head). i think they actually had a test on here somewhere where they took JJ olsen's sfwd car and dave from headgames ported a full race b16 head dynoed and replaced it with a same ported head but now a gsr from dave and made 40-60 whp difference! ****** crazy!
but the fact that b16 cams suck too always defer me to never buy a b16 head.
