Hey everyone, i have been doing searches and coming up with some disturbing results.
People have been saying their b20 swapped G2’s are running 15.8’s - 16.5’s. Which seems Insanely high.
I used to have a CRX with a 1992 B18a swap, I/H/E and Crower 403’s, running 14.4’s on street tires with 2.4 60’s, easily a 13 second car on slicks, mind you it weighed a meer 2200 lbs, a G2 weighs a heafty 2600 ish, but this not nearly accounts for the slow times ive seen.
I would like to see a list of peoples times/ engine mods on b20’s.
Please state your mods, as well as engine type ( b20b, B20z) and if u have a p8r head, please state that too.
I would just like to see if these #'s are the norm for a b20 swapped DA teg, or if its just a few rare cases.
I just want to make sure that the engine will be decently quick before i sell my 2001 Civic, and buy a G2 and swap a b20.
people have said the b20 feel almost the same as b18, exept that there is slightly more torque but cant rev as high. In the end, the power output is the same. If your going this way and you like mecanic, give it a b16 head and there you go.
Im still not sold on LS/Vtec or b20/Vtec’s reliability. I will be commuting 200 km’s a day to school, and i need a car/engine that can do it 5 days a week. I know if its built right it will be fine, but i dont have the $$ and time to put in rods/and all the work that comes in building a solid LS/b20/Vtec
i think the times u have seen are from amature drivers and people who dont know the way to drive a b20. a guy on here. that lives near me ran a 15 flat on a b20b i believe. o and the motor was stock. so if u can drive then u should pull off some low 15 sec times.
MY PERSONAL THOUGHT is this…i say go gsr… Honda spends a billion dollars a year in R&D, if there was supposed to be a motor with that kinda power and realiblity… they would have made one… i have seen b20 motors make good power… but with any motor… in order to make good power… u have to build it… so i would say go gsr… if ur buyin a g2… u can pick up a gsr stock in the car… not as much tq… but still a good hp motor… and it can handle a high rpm…
of course if you can spend a few grand go GSR
as for the b20vtec, if you plan on driving 5days a week, just dont go over the stock redline and will not have anyproblem. youll have a better flowing head, better intake manifold, vtec (raorrrrr) and a 2.0L block.
i was thinking more along the lines of a b20z/p8r head, crower stage 402’s, I/H/E, b18b IM and boring / tapering TB. Should give me about 9.6:1 + 0.4:1, so about 10:1 compression with the block/head combo.
90’ LS DA, B20b, worthy bolt-ons, stage 2 weight reduction (lol), gutted rear portion and passenger seat. Running stock 95 LS cams, bald falken ziexs, LS tranny.
Best: 14.6 @ 95mph
I should be running low 14 second passes now, Thats with a sunroof plug, jdm bumper supports, more BS pulled out. And a street tune on the wideband on my AFC. Should be installing my 3 FAL windows in the rear portion soon.
I would recommend a b20 for an integra owner far before a gsr engine, if money was any consideration. A b20z bang for the buck/daily drivability can’t be touched by the gsr engine swap.
One day i ran a 14.4 in my gsr hatch and some kid with a b20 swapped civic sedan hit a 14.7, right off my back bumper.
That said, i only hit a 16.48 best, when i had my lower cr b20b in my '90 integra. Stock pea shooter exhaust tho, and crap tires, no tuning, plus first time at the track. These engines seem to run much better obd1, …plus 4-1 header, 2.5" exhaust…140+ whp possible. do it
B20 is a great swap, since i am now boosted i would have rather bought a LS, but I still have yet to encounter a problem soo i guess i have no complaints it is a nice easy swap (course what honda swap isnt)
