I have a nice low mileage gsr bottom end that i want to put my sir b16 head on. I searched and found alot of people putting the gsr head on a b16!!! I always thought puttin the b16 head on the gsr was the better way to go. thanks for any input.

 

I have'nt seen alot of people using the C1 head on a B16! But you are headed in the right direction with what you got. It's the poor man's Type R. Good stuff.

 

doesnt b16 head on gsr blocc lower compression? correct me if im wrong

 

no it does'nt......

 

im almost positive it does maybe not on with an sir. isnt the combustion chambers on a gsr head smaller than on a b16. this is what i came across while searching for a head for my setup wanting to build a high compression all motor setup. i was going to go with a gsr head cause it bumped the compression up a few .points dont remember exactly you can check it on one of the compression calculators. but then i found a really good deal on a ctr head and it didnt matter to me anymore.

Yes, compression will be lower than a gsr.

 

"However, GSR heads have a distinct advantage over B16/ITR heads. Although having slightly smaller combustion chambers that raise compression is an advantage, it is the reason why it raises compression, that is the REAL advantage. You see, GSR heads employ flat surfaces in the combustion chamber called "quench" pads. They do raise compression, but the real advantage is this design's ability to deter the possibiltiy of detonation, promote better flame travel, and aid in cooling."

If you plan to use the gsr bottom end in stock form, go with the p72 head. Honda engineered that head for that block. Like the others suggested, the pr3 will lower your compression.

 

p72 for compression.

 

what if i go with a single layer head gasket? Would putting the gsr camshafts in my b16 head be a good thing to do or no? thank you for all the input everybody i really appriciate it. the b16 head flows better than the gsr head correct?

 

I have the gsr block tore down to ring and bearing it. I wanted to have the deck surface cleaned up what would be a good amount to have ground off to get my compression back up.

why not just practice with this for a little while. i depending on what you want to do witht he motor is to how much your going to notice. your pretty much building a poor mans type r. i think the difference in heads is going to be around .2compression if you run a 2layer head gasket that pretty much makes up for it and brings it back

 

if you plan on doing an work on the head such as cams and a port than choose which ever one is in better shape. once you change the port design and headflow the b16 will make more power than the gsr stock would. its up to u which you choose. but both ported it doesnt matter which you choose there both gonna perform the same.

 

Well from what i can gather the gsr would have 10.00 comp. With a 2 layer head gasket and if i take .015 of the deck height my comp would be 10.4. What do you guys think about that? Also Does anyone know about the gsr cams vs. the b16 cams and would i gain anything by putting in the gsr cams and not any piston to valve clearance issues or anything like that. Thanks for everybodys help.

 

im lookin for arp rod studs for the gsr block and cant seem to find them anywhere. Does anyone know where i could find them?

only reason alot of ppl dont like to remove any off the head or the deck of the block is if you decide to use the head or block on something else or decide to go a different route latter down the road. why not just invest in some pistons like find some type r pistons or even b16 pistons thatll put you at 11.1:1 with b16 head 11.3:1 with gsr head with oem 3layer head gasket and run stock rods be even higher if you can find p30 b16 pistons. all im saying you remove anything off your head or block you cant put it back on you decide to go a different route or put different pistons in it later you might have piston to valve clearance problems just might want to keep that in mind..

Try looking for rod bolts instead and you'll probably find what you're looking for, especially on ebay etc. You really should do some more reading and searching to learn as much as you can.

 

Ok Im taking your advice on getting new pistons. I found this place on called nippon racing in Japan. The make aftermarket honda and Mitsu replica pistons. they have a kit that includes brand new type r civic pistons and king race bearings and rings and every gasket and o ring. Check it out on ebay item # 150187468831. They give you a virtual tour of the manufacturing facility and have 100% feedback. Let me know what you guys think. thanks again.

 

yeah i did but i looked for studs first because thats what they actually are. I have to have the rods re sized or at least honed after the new bolts right?

 

only thing odd i notice about that particular ebay item. the title says jdm b16a pistons.

jdm b16a pistons are p30
usdm b16a are pr3

but the pictures of the box states pr3 which doesnt make since to me if the title states jdm b16pistons and the box says pr3 imo id stay away from ebay adds.

either pistons will bump your compression up but that ebay item seems kinda ify there.

NPR products are very good. I have used them on a few builds and always had excellent results with them. The craftsmanship is identical to OEM pieces when comparing the pistons to stock units.

 

I did the same thing, i put a 94'' jdm b16 head on my 98'' gsr block but before i put it on i took it to Napa and for around $200 they did a 3 angle valve job hot tanked the head, installed my new oem valve stem seals from honda which cost around $50 and resurfaced the head. After i installed the head the car ran strong and felt alot more faster once v-tec hit which was around 5800rpm-6000rpm. I did no tuning to it after just checked the timing.

 

I also forgot i had the cams that came with the jdm b16 head measured and they were more agressive than my 98'' spec gsr cams so i used them instead, and my opinion on the ebay ctr piston set is its a rip off i dont think they have a good warranty and even if they did why risk your bottom end for some imitation pistons i almost did the same thing until i found out the oem parts are the best so i ordered oem jdm type r pistons from honda couse the ctr pistons would have a very high comp. ratio to tune on 91 pump gas for a daily driver and so i got acl race bearings and everything else from honda and built my bottom end but since i went with the jdm type r pistons i would get the most comp. with a gsr head so i got a 99''gsr head and built that also! hope that helped

 

Might take a look into RS machine. wich is the pistons i bought for my ls/vtec setup and they came with the treated heat coat on the side skirts http://rsmachines.net/pistons.html but i havent got to run my car yet waiting on machine shop that has had my motor for over a month now but theyre pretty much doing it for free as a favor to my boss so i cant really complain too much

No, they are bolts not studs. A stud is like a bolt but has no head, only threads on both ends. If it has a head, it's a bolt. You don't have to resize or resurface anything to use stronger bolts....think about it, you're only using stronger bolts, not bigger ones right?
