What compression ratio with this yield?

Same Headgasket?

What timing belt?

Thanks!

 

dont do it unless u plan on boosting or something cuz it will lower your cr

why should he boost ??.... b16 head on a gsr block will raise the compression....good for all motor with a type r tranny .....put type r pistons ... you have pretty much a poorman's type r.

 

no it will lower compression

You can get a general idea of compression ratios with different head and block combos with this calculator: http://www.c-speedracing.com/h...c.php. Won't be exact, but you get a good idea of what direction you're heading.

The B16 head will decrease compression with a B18C1 block.

 

I had the exact setup in my CX last summer, Stock B18C1 block with a B16A3 head(all RRR head internals) and a RRR LSD trans.

**I used the Type R Head Gasket and the Type R Timing Belt and it will decrease the Compression Ratio**

there really is no reason for doing this.....

now i can see putting this head on if the original poster messed up the p72 head and has found a b16 head cheap. but to take off a perfectly good head just so you can have a "poormans itr" is kinda dumb

if he really wants to see some gains he should throw a set of jdm r cams in that thing, and slap on an AEBS intake manifold. i did this to my stock gsr and could not believe the top end pull that intake made and i still have the stock tb and exhaust cam. i wish i could have used this intake manifold on my last gsr i had i think the power gain would have been quite a bit more with the added compression from p73's

I had the b16a head/tranny on my gsr...Ran very nice. I would def. recommend it for an all motor.

 

I'm turbo charged with a b16 right now. i'm looking to go to a b18c block for more displacement and power, and hopefully lower the compression ratio.

what about the b16 block related parts like the oil pump and water pump? different for b18c?

So i need the b18c or type-r timing belt and HG?

</TD></TR></TABLE>water pump and oil pump are basically the same, if you want more pressure switch to a crv oil pum, same p/n as itr

also you should use the b16 gasket and t-belt

 

b16 t-belt??

I was thinking i needed a b18c or ITR belt because of the taller deck hight?

 

you do, type r or gsr belt is needed for that block.

 

My friend has a b18c1 block with a b16a head. We used a GSR water pump and a GSR timing belt. We also installed some ITR Pistons & Rods also installed some CTR cams and Valve train. His Poorman's ITR beats up on real Type R motors. I think it's because it has slightly higher compression due to the Cosmetic Head gasket and it's running a custom obd1 p28. Plus all the bolt ons.

If i was you I'd use the GSR Water Pump and GSR Timing Belt. If not i suppose you could use a ITR water pump and ITR timing belt. The ITR water pump pumps more then the GSR one. Also with a Cosmetic head gasket you could yeild the same if not higher comp ratio as the GSR. (i think) Are you going to run stock cams? Pistons? Do you have the GSR head?

 

i'm going to slap my b16a head on the GSR block. Thanks for your help

this should give about 10:1 CR and a lot more power than my 1.6

who has a gsr short block?

Will everything else from my swap work?

ie alternator, engine mounts, intermediate shaft....?

 

whats funny is that i have the exact opposite setup as you now ... i have a b16a2 bottom end and a p-72 gsr head ..... everyone tells me that this combo makes more compression

my all motor car is set up the same way, and it does yield more compression due to the shape of the gsr's chambers, i have oversized ctr's in my b16block and the head has skunk2 stage II's...i wanted to switch to an ls block, but they said w/ all the same parts, ie pistons, etc..using that gsr, the compression would be way too much...

fyi to those that dont know, increasing the bore, completing your chamber will also lead to more compression

that's cool

how's that working for you ?

you have any numbers ?

 

bump for caculator

oh and what about my tapped b16 oil pan? will that work on a GSR motor?

are all the oil pans the same?

 

wouldnt it be wiser to do a B16 head w/ a B20z block?...im not sure if i would lower the compression?
