B18a1 Block With Which Head?

[dietre]

OK, i got my hands on a b18a1 engine (93 LS integra - non vtec) NOW I am rebuilding the block with a GSR crank, new 11:1 compression pistons, and with the head I am going to get Skunk2 cams, gears, retainers, valves and springs. Now my major question is will any year head fit the block. Can I use like a 96 GSR head or type R head or a B16 head? I know i have to run an oil suply line to the head but I am almost postive the heads will fit from any year to a B series block.

Can any please Verify this? and if It can, what do U suggest i use for the head B16, GSR, Type R

Well I really don't see the point in swapping out the crank out of the LS block for a GSR. But you can make any of the above mentioned heads(B16, GSR, Type-R) fit the LS head with modification. Year doesn't matter. Just as long as you have a distributor that fits your chassis harness(OBD-1, OBD-2).

Now about which head to run. Depending on the dome of the piston and what motor the CR was calculated for. A GSR head will give you a slightly higher compression ratio. I would really have to know what cams you plan on running specifically to give you a good idea of where you want your compression ratio to be so as not to either overcam or undercam the motor. Cam choice will also have to be dictated by alot of other things. Like IM, header choice, exhaust size, etc. . Do you plan on having any port/polish work done to the head you decide on getting?

Its really hard to help you on your setup with basically no information. But to answer your original question. The year of the head doesnt matter and any of the mentioned B-series Vtec heads will fit on the LS block with modification.

I've got a B16 head for sale in the classifieds. If you're interested, make me an offer.

YES to the port en polish.
Skunk 2 stage 1 cams will be installed. stage2 cams might run at to high rpm for everyday street driving. Can U bore the cylenders to run larger pistons for increase displacement? if U can by like 30 over pistons I would be doing that as well. Skunk2 hearder with a skunk2 exhaust possible Tanabe (2.25")

{I realy like skunk2} I heard the gsr crank is a longer stroke.

I want to make at least 250hp with this NA engine.
i've been told that the b16 head flows better than the gsr. Im also trying to get my hands on a typeR tranny. and I also have the front axels from an Integra to swap into the civic.

gsr crank is shorter stroke not longer, its good if you wanna turn more rpm to make the r/s ratio better that and the bearing size is a lot better than an ls, to make 250 your gunna need more than stock pistons and a whole hell of a lot more cam than the junk2 i mean skunk2 stage 1. Your gunna a much better header, and your gunna need more exhaust. 250 is NOT a very streetable NA application. The b16 does not out flow the gsr head at all the Best casting from honda by far is the gsr, the valve angle is the only down side to it...but its only 1 degree difference so it doesnt matter. I hope you plan on buying race gas cause your gunna need in excess of 13:1 compression to make those numbers...and thats where the cam comes in...your gunna need big cams, your also gunna have to rev to at least 10,000 if not more. People dont understand what it takes to make that power...If you know the import scene at all...Leslie Durst's all motor crx didnt even make 310hp and she went 9's. Bisi doesnt make more than 320...he goes 9's And you wanna make a 250hp street car? lets put it this way...we tuned a gsr with ctr pistons and an ANR header(one of the BEST flowing headers on the market) crower cams, Edelbrock intake mani...lots of other stuff...it was a 13:1 motor on race gas...and it only made 196, on our own dyno(we didnt build the motor). And that was running it borderline we are talkin 13.5:1 air/fuel. So you might wanna look at what your really trying to do...250hp is Not a simple bolt and go thing...you got a lot of stuff to do...be looking at spending right around...7-8000 to build that motor.

Jeff at IB has built some 250ish WHP motors, and I believe they were street driven...but not cheap.

[Hybrid_Coupe]

im not saying it isnt possible to build a 250hp street motor...just not the best idea...

[dietre]

if a stock gsr motor has 175hp than all that work was 4 shit to get 196hp. if thats the case, im just gonna rebuild my block and turbo the mother.

I agree...not very streetable, definitely need a smog hookup, and not a great idea on shitty CA pump gas.

You're confusing crank horsepower with wheel horsepower. A stock GSR will make about 150 hp to the wheels. You're going to need to up the displacement to at least a 2 liter to make the kind of power you want. Check out www.importreview.com for some dyno charts of various setups and displacements.

turbo is the easiest way to make that much hp...but im not gunna try and talk you outta goin all motor...its pretty awesome if you wanna spend the money.
