ok well i have an obd2 gsr at the moment, im going to do a rebuild soon. my friend is selling his obd1 b16 head so i was wondering..would the head fit directly on my block without having to do any head work? also since its obd1 could i use it? i know this combo makes the poor mans type r. im planning on using skunk2 valves and retainers on the head. also wondering what the power gains would be if any? and would i only be able to use b16 cams? i would need a b16 headgasket right?

thanks to all input :goodjob:

The head should bolt right up, a B series head is a B series head. And I think you use any B series cams.

The bore will be larger on the GSR, I'd think you'd need a GSR head gasket or a B16 gasket for a bored B16.

so i would need to bore the b16 head?

No, the bore of the block.....

My z28 came with a 350, it was bored to a 357.....I need a head gasket for a 350 bored .040 over, see what I'm saying.

Never swapped stuff on Honda so wait for someone else, but I'm sure you'll use a B18 head gasket.

No, the bore of the block.....the B18 has a larger piston diameter. If you get a B16 head gasket the holes where the pistons come up won't be big enough.

yea i understand what your saying.
i thought all bseries pistons were interchangable? minus the b20 ...
il see what some1 else says. rep'd for help :goodjob:

u are set b16 or gsr head gasket u pick they are both the same.

Got it, that's why I said to wait lol

BAREFOOT: o ok. would you happen to know the power gains/advantages if any on this combo? and which set of cams i could use? b16 or gsr?

BAREFOOT: o ok. would you happen to know the power gains/advantages if any on this combo? and which set of cams i could use? b16 or gsr?just an fyi there is more to a poor mans type r than jsut a head swap. u will need itr internals to do it correct an really call it a PMTR.

me personally i would just stick with the gsr head. i just dont see any real power gains over switching. stock for stock atleast.

i thot a poor mans type-r you would put type-r pistons n cams. but my freind has a poor-r n that shit pulls. gl with it :)

I would get the other head and build it and when you are ready swap them over. No sense sticking a stock head back on.

fyi i have a head gasket that will work for u in my 5 10 25 sale. I'll take a look as soon as I can. Also u said I would need itr internals to make it a real PMTR, I wanted to build the head with skunk2 internals (planning on boosting soon after the build) so that would still count as a PMTR right?
Sorry for being repetitive just want to be sure of things before I buy the head or not.

poor man type r is basically a gsr block with itr internals, b16 head with itr cams....you can upgrade parts but that the basics...

If you're gonna boost, you might look into lowering the CR.

marcos713
09-21-2009, 08:24 PM
^yea I knw so I'm probably not gona buy the head. Ima just build my gsr head and bottom with gsr internals. I knw itr's have too high a CR to boost

A LS is the best for boost. If you're buying new Pistons just get lower compression ones so you can run higher boost if you feel the urge.

Slaping the b16 head on a stock gsr block will lower your compression to about 9:8 while the stock gsr long block is around 10:1.PR3 head (b16,type r) flows better than a p72(gsr) head due to its larger combustion chamber.(For you V8 guys reading)Its like having an LS1 bottom end and deciding wether to put a set of 243(ex.p72) casting 5.3 vortec heads or the ls1 heads(ex.pr3) the ls1 heads flow better but the fact that the 243's give higher CR will end up giving you more power on the stock block same as what im trying to explain in the pr3 vs p72 subject.So in general If you are planing on boost PR3 head is the head for you if your gona go all motor on the stock b18c1 block stick with your P72 head.To me sticking with your usdm p72 pistons are useless for a build. Again boost pr3 head.Stock block If you want a poormans R a good budget build for me would be pr3 head(upgrade to dual valve springs)R cams slap some p30(jdm b16 pistons) and arp rod bolts compression sould be around 11:3.If your going allmotor and using your stock long block,R cams and some pr3(usdm b16 pistons) should do the trick 11:3 compression also but in the border of 11:4 :2cents:

ok i understand the setups you broke down to me.

so if i go boost with the b16 head what pistons should i use? would p30s or pr3s be to high of a CR for boost? or should i just get some JE gsr pistons?
i will be getting my bonus next month from my job so im trying to make a list of the prices of internals im going to need so i can buy them all before i start taking apart my motor.

anything with low comp. oem if u want to stay in the low boost and cheaper range. aftermarket just in case u feel the need for more boost 1 day which will happen.
would p30s or pr3s be to high of a CR for boost? or should i just get some JE gsr pistons?yes and yes

What kind of power are you looking to make when you go boost? Also, what size turbo are you planning on running? 250whp-300whp you can just run a stock gsr. 300-400whp you can do a rods and pistons gsr. I don't see a big gain in using the B16 head if you plan on boosting later. I would put that money towards a good turbo and tuning. You don't have to do valves and springs and retainers unless you plan on running high rpms (above 8500) or run big cams (not needed for <400whp). As for what pistons to run I would personally run a 10:1 JE and get the car tuned. This will make the car a little more responsive when out of boost and you won't have to run as much boost to make good power.

as for power im planning on anywhere from high 200s to mid 300s. not planning on high rpms just my redline. not exactly sure about turbo size yet, manily focusing on my rebuild at the moment. im planning on getting eagle rods and JE pistons. so i should be ok buying OEM internals instead of the skunk2? i just wanted to have a peace of mind knowing the head is built so if something goes wrong i wouldny kick myself in the ass for not building it right the 1st time.

If your going for that power range then building it is not must the main factor people blow their engines running boost is because they are not tuned or they boost an engine that is not healthy.I guess you can say a good set of rods and some low comp. pistons should do the trick as for the head for that power range could be left stock 12-14 psi should give you the power you are shooting for I believe...

if you were to go the stock route, atleast change out the valvetrain in the gsr. as gsr heads come with dual valve springs on the intake not the exhaust side.
