i was wondering, does the bottom end of hte gsr give the motor its torque? i went from a gsr to a jdm b16 and i miss my torque, anyone?

my buddy might be gettin rid of his bottom end of his gsr, which i can get redone and put my b16 head on it.. thenget the sucker tuned.

anyone?

Um, displacement?

Sure, slap that b18c1 bottom end on there. But If i'm not mistaken you'll have less compression than a regular b18c1, so slightly less power.

Or maybe I have it backwards. Lemme check a compression calc.

EDIT: Yes, you'll have ~.2 less compression if you keep the p72 pistons.

ok, well it will get boosted sooner or later, within the next year or so, ( hopefully) should i just keep the b16 bottom end?

i just miss my torque and can get ahold of a gsr bottom end that needs new rings and such, so new pistons would be a must anyway.

The stroke on a GSR is better than a b16.

im just trying to think, if ic an do a low budget build with the gsr block and me not spend **** loods of money if its not gonna be anything special, i do have lots of trans work done, so thats why the car is pretty quick as it sits. but id like to have more torque.

If you are going to boost it, by all means, get the gsr bottom end and keep the low compression. The rod/strok is better for boosting and the lower compression will allow for further retardation of timing.

basically, you'll make more power on a lower compression boosted setup more reliably.

A GSR has a 87.2mm while the b16 has a 77.4mm stroke. The b16 has 10:4 CR while the GSR has 10:0 CR. BUT the the gsr has 202cc of more displacement. What the b16 lacks in stroke, gains in CR. The GSR has slightly less compression but makes up in stroke and displacement. Which gives the GSR (b18c1) 10 more hp and 17 more ft lbs of torque over the b16.

do you think the 17lbs of torque is worth a couple hundred bucks? im not trying to get 400 horses to the wheels jsut maybe want 280 to the wheels when boosted just til then was seeing if you guys think its worth it then to get the blcok from a friend

yoffer

I would say get the b16. i was just answering your question about where it gets all the torque from. To me personally, its not worth the extra $$ for 17 ft lbs of torque. But some people feel they need that little extra just to say that they have it.

im gonna say its not worth it if your gonna boost either way

thats funny, becuase one of my friends nephews is getting his B16 with a GSR head and a SI tranny

great set up right there

Kid knows what's up.

iTrader: (1)

the obvious displacement advantage and dual stage manifold of the gsr helps with the torque. the tranny helps you use it.

b16's are very peaky engines which is why they have really short geared tranny's.

b16 head gsr block = poor man R

the stock cx

the crank on the gsr gives it more tq than b16. what you can do is get that gsr block from your friend for a cheap price, take the pistons out your jdm b16 get em pressed out and pressed on to your gsr rods might cost no more than 75-100 at a honest machine shop. static compression would be about 11.0 to 11.3 depending on the pistons from your b16. slap the b16 on the gsr get yourself a really good tune and you have a decent daily driver. as for boost your going to have to go a different route depending on how much power you want. but right there is your best bang for buck if you want your tq back and some.

Actually the usdm pistons will give him 11.4:1 and jdm pistons will give him 11.64:1 if he's using an oem headgasket.

PhoeNix007EG

so, gsr bottom end+ usdm gsr rods + jdm b16 pistons+ and usdm b16 head= 11.6.1 compression, and decent torque numbers. ide probably throw on some skunk 2 stage 2 cams, and springs, retainers, cam gears. does this sound like a good idea for my daily. i was thinking about going jdm h22 type s, but this sounds like a easier and more cost efficent setup. any ideas/ help ??? oh, what tranny would be best suited gearing wise for this motor. b16/gsr/ do either of those have a lsd ??

You are all wrong, the gsr gets it's torque from the torque fairy. Thats why honda casts their blocks a year or more before they are used, because they have to stick it under a pillow for a few months.

lmaoooooooooooooo

i think what there saying is just take a gsr crank take the rods and pistons of the B16 and put it back in B16.. dont get an H22 stick with what you go a type s h22 will run you the same as a B18 if not more .. and as the for trans they both could have came with an lsd (the jdm verson) gearing the gsr has a little longer then the b16 (so im told) i my self just orderd a B16a with the clutch lsd from Hmotors theres also the gear wich is more i guess, streetable

the stock cx

yes, i guess i forgot that the compression ratio i was giving you was for a b16 head on the gsr. the compression for the gsr head with those pistons are lil higher but your friends only selling the bottom end right? also depending on the pistons you use. im not sure what kind of jdm engine you have, you migh have the sir1, sir2, or even the civic type r. the one with the pr3 pistons or the p30 pistons, pr3 are the same as the usdm b16 pr3 pistons. p30 will bump em up alil more. depends on what piston your using.

Why are you ranting about h22's?
