need help on deciding!!

 

What do you plan to do with your car?

 

Whats your budget?

 

93 del sol and any budget

 

well if they are the same price (which i really wouldnt think so)
gsr all day
but in the end it all depends on price on both of them

 

Well, i own both. There are two different kinds of B20 btw, he better one is the B20Z, and it actually out performs the gsr, as well as cost less. Because the B20 is under rated from factory, as well as makes more torque, it actaully makes more power than the smaller 1.8L gsr

 

B20Z 146hp 133 ft·lb
B18C1 170 hp 128 ft·lb
(Stats from h-t or hondaswap)
exactly how much did they underrate the b20(?)
cuz a 94-01 gsr would hand it its ***
although the 92-93 B17A1 might be a good race lol

 

^^ does vtec makes a difference???

 

B17 is torque-less, it would get its *** handed to it. It just has an orgasmicly amazing rod/stroke ratio. And how is the B20 under-rated?? I'd personally go with the B18C1.

 

If you live in CA, B20swap would be illegal due to putting a light truck engine into a passenger car. That leaves your only choice of B18C1.

 

However if you aren't hampered by rediculous laws, the B20/Vtec may be a better choice. It may have a little lower peak HP than the GSR, but more torque everywhere else. You can't rev it as high unless you change the rods, or at least their bolts.

FYI its not because they underrated the B20 - its because few people have realized that a broad powerband can usually trump a higher, yet peaky, powerband. The B20 with a dohc vtec head will make even more torque everywhere, expecially in the upper-rpm's.

 

the b20z is actually underrated, its stated to be 150hp in many european countries and 155hp in cyprus, the b20b is also rated 128 and 133hp!

and also remember that your most likely going to use ls parts with this swap like the intake manifold,exhaust manifold and ecu all which add hp and turn your b20z into a 2lt b18b, 142hp divided by 1.834 times 1.972 gets you more than 152.5hp and thats before what ever hp the extra 0.4 compression the b20z has adds! I figure it would be likely to see around 155 hp with ls parts since there is a b20z out there already rated that stock and since thats what hybrid gcarage got with there experiment with the b20z(check b20z dyno hybridgarage on yahoo) 155hp(6200)and 140 tq(4800rpm) sounds like it could give a 170(7600rpm) 127tq(6500) engine a hard time specially if it was mated to a short sir,itr or gsr tranny not to mention the b20z has much more potential to add hp, you can vtec it later on but you cant double vtec the gsr can you?

I had the b20z with ls parts in my eg along with simple bolt-ons and I never lost a race to a usdm dc2 gsr, I went head to head with a eg vx gsr aswell!!! and my car was a better dd with the b20z too!

 

yeah, cali is known for their crazy state laws, like ref's, and needing to get swapped motors bar'd. makes me very happy to live in hawaii now. we don't have smog, and you can do pretty much anything to your car. legally put any turbokit on a car, swapped jdm, edm, pretty much any motor...

except our prices for parts here, or shipping from the mainland is ****ing outrageous.

 

ok, maybe we should read the thread better guys.

he asked which one is better? b18c1 vs b20(non vtec)...

if you want overall power than gsr is the way. b20 has more torque than the gsr(but not by much). if both stock motor were swapped into the same car, the gsr would win. also, do some research man, theres alot of info here.

but if you were talking bout putting a vtec head on the b20 then that would be stronger than the gsr. but also, will not be as reliable because you're swapping heads and wont be a true factory engine.

 

How?

Easy, its rated with a POS exhaust manifold. The manifold is so restrictive! Unlike adding a header to a B16 or B18, when you put one on a B20, the gain is huge...adding like 14hp and 3 ft lbs torque. A gsr will NOT beat a B18C1 engine for engine

here is pic of the crapola B20 oem manifold



The B20Z also has a broader powerband with tire breaking power after 3000rpm right to redline.....lots of useable power

 

im gonna tell you str8 up your wrong in stock form the b20 will get its *** handed to it all day... another important note your saying all this crap about the b20 you do not even know what tranny he is gonna use.

ive seen gsr powered with bolt ons eks vs b20 powered with bolt ons ek's i will say this they leave the same pretty even but the gsr revs out alot more its gonna pass the b20 no matter what. both car were using b16 trannys... stock for stock the b20z will lose period... no bench racing ive seen it in person. also the drivers swapped cars to see if it was driver error. b20 lost again. the kid with the b20 got a vtec head about month later so he could whoop some ***..

gsr puts down about 150-160 whp stock form. 115 ftlbs
b20z its ratted at 150 hp in some countrys its still putting down b16 hp 130whp-135whp
120ish ftlbs.
in the same car with the same tranny, in a 1/4 race the gsr will beat it with equal drivers.period nuff said. b20 in stock form are garbage

 

I love how people "without" first hand experience argue with some who has actually done it. And stock gsr's don't make 160whp!!

 

I'll I've got to say is I beat a b20z with'98 spec itr tranny eg hatch with my stock b16a y21 tranny eg hatch, both hatchs are cx. I had him at the top of first gear and continued to increase my lead throughout the gears, no misshifts or anything for both of us. B20 isn't above all end all.

 

Tranny's make a huge difference in performance, no doubt. What you beat in your car doesn't prove much. I have a B20Z in my hatch with Toda flywheel, an exhaust and LS tranny....my car kills gsr and type r integra's, but what does that prove? Too many other elements involved, a persons car weight, other parts, driving skill......

Many people don't realize there is a definite difference between the B20B and B20Z. Also, nobody ever considers the powerband, it is not all about peak numbers when looking at power output.

 

i've own both setup, B20b (JDM) w/GSR tranny...and B18C(1) (JDM)...for stock vs stock, B20 with LS intake, and B16 exhaust manifold...B20 has a good power band...i have raced my buddy GSR(s) and got my @$$ handed to me after 2nd gear...

I love the GSR (vtec and accleration) and the B20 (powerband and FULL THROTTLE sound) was...If I remember correctly...I felt the powerband as low as 2000 or 2500 rpm

ps - guys...with the b20 i never! rev past 6200...so i dont know if that was my downfall or not...but it last me over 4 years...and she is still ticking! (and see she 6K almost every day)

to the original poster...it really depends on your budget...and what you like sir...if you want a GSR, wait and save up...if your dont have the money...but you still want to have fun and SLOWLY build the motor...B20z is the way to go...and possible VTEC in the future. good luck sir!

 

both are good daily drivers.. but the gsr will outperform a stock b20 motor.. unless its a b20vtec.. if you want performance then go to gsr.. if you just want alot of torque for daily driving and picking and dropping people off then go b20..

 

b18c ive owned 3 motor all ran beautiful and an 8k redline never hurts

 

just get a b20 and vtec head.
more torque ftw.
