Differences in the blocks?
Whats the difference in the block of a b18b1 from an ls and a b18c1?
I mean if theres no difference then you should be able to take an ls block and put on a gsr head and its basically a b18c1 right?

Re: Differences in the blocks? (duscar)
the LS block has a longer stroke then the GSR block
stock wise the LS cannot handle high revs , the gsr block can handle more if we go the stock route
theres more to but im tired and im going to sleep hahaha

Re: Differences in the blocks? (in10ceCiviC)
the b18c1 has larger diameter rod bolts, tri-metal rod bearings, internal vtec oil passage, oil squirters, a main cap girdle, 2 tooth water pump and upgraded oil pump compared to the b18b1 block

No.. the combination between the longer stroke of the b18b and the vtec head turns it into something slightly more powerful

does it really? the only reason im asking is im looking for a gsr but trying to find one with low mileage and in good condition is kinda hard. So i was thinking of just getting an ls and slapping on a gsr head. I know the interior is different but still, if its going to basically be the same thing then thats what ill do.

Re: Differences in the blocks? (duscar)
What your referring to is also known as an LS/VTEC swap. You can search it on H-T as it has been performed successfully many times.
If you are leaning towards all-motor then you could also use a B20 block found on Cr-v's. Not a legal swap though in some states since the B20 is considered light truck/SUV motor. AKA CRVTEC
You could also use any B-Series Vtec head instead of the GS-R which would give you more options of an Intake manifold.
There are some modifications you will have to perform on the head and also buy an oil line kit from someone.

For the 94-01 non-ITR models, only the 94-95 USDM GSRs had the cooler. All ITRs had the cooler. The ITR and GSR share the same block.

Re: Differences in the blocks? (duscar)
The itr head will be far too overpriced imo. Its a slight p&p from the factory and valvetrain will let you rev slightly higher. Better off to port and polish a gsr head and get an aftermarket valvetrain.

Not sure. I know you guys have stickers. I have bought my last two cars from Texas (no rust)
You would have to ask around. check DOT laws.
Otherwise you are limited to 3 heads to pick from. B16 (PR3's) B18 Type R (PR3's with factory pnp and valvetrain like mentioned) or the B18 (P72 GSR)
The type r I just got one for around 700.00 shipped no dizzy and gsr cams (already have 01 type r cams) but can be anywhere from 600.00 to 1400.00 brand new from dealership.
GSR heads go around 600.00 shipped complete with everything including intake manifold.
B16 heads for 1st gen are worth around 300.00
2nd gen and usdm b16a2 heads are worth at most 500.00 because they have better lost motion assemblies.
These are prices that I would be willing to pay on the very top side. No way would I pay 600.00 for a b16 head complete with shipping. But idiots try to sell them for that much.
I am also talking stock heads with no work done to them. You are paying more if they have valvetrain mods, or port work done and then you have to worry about who did it and the quality.
Living in Dallas area you should check out the regional marketplace and check the DFW thread. There are all kinds of stuff being sold in your area. Check out hondabride or 99slammedcivic. They usually find top notch stuff. there are a few others in the area I have dealt with since I have been to Dallas a couple of times picking up parts.
Hope this helps and there is a good thread about b16 and gsr heads. The flows are basically the same with the gsr just a little better. But has a different combustion chamber design. Both are equally good heads.
Good luck.

The b16 is known to flow "slightly" better.

Thanks for the help, coming from VW's i dont know much about Honda's but like i said im looking for a gsr. So i know a b18c1 would outperform the b18b with a vtec head but how much better performance would the b18c1 be than the b18b with a gsr head?

..No. Lsvtec will slightly outrun the gsr.

Both statements are untrue, they outflow each other at different RPMs,
and it's not even enough to be really noticeable at all.
There was a dyno, or some type of tests done, and it was also on a thread here.

Re: Differences in the blocks? (duscar)
As easy as a golden eagle lsvtec kit. Just a slight oil tap in the head,and a sandwich plate that runs to it from where your oil filter goes. And switching your dowel pins one spot over. A n00b could do it
