b18b questions

[crabby760]

hello i just got a 98 ls b18b1 it has 66k miles on it... i was curious if its worth it to go all motor on a ls engine if so what is the best way to go in order to get the most horsepower out of the ls and if anyone can tell me what is the most they have seen on a all motor set up for a b18b1 LS MOTOR

[mellowboy]

Well its really hard since the motor is not made for high revving and the head flow is not as good as the vtec head. The only way i can see you achieve the 200 whp range is get a vtec head and build it right. The most i've seen was 204whp and it wasn't easy and more expensive.

what do u think i am looking at with these mods honestly

intake AEM
header Dc 4-1
exhaust 2 1/4 custom cat back
crower stage 3 cams
skunk 2 cam gears
safc controller
fpr b&m
skunk 2 intake manifold
skunk 2 ecu
crower valves/springs/retainers
stage 3 port & polished head
je hiigh comp pistons......

fully dyno tuned????

To be honest...its really hard to say. I would probaby guess 170 whp? Don't quote me on that.I'm sure you'll get lots of torque though.

hmm ok cool deal.....

[got v-tec?]

with those mods your looking at around $3500 for 40whp
for that price you could slap on a gerret t3/t4 t57 turbo w/12psi boost on stock internals and have 250whp
or the fast cheap route is get a b16tranny and 55shot nitrous (170+whp)

yea i can atest to that claim, my b16 has about 95% of the mods you listed, and im hoping for 200crank HP, i do want to run a high c/r s/c system soon tho.

[crabby760]

what do you guys think of this set up?

ls/vtec b16a head

port polish
i/h/e
crower stage 3 cams
skunk 2 cam gears
skunk 2 intake manifold
crower valves/springs/retainers
fpr b&m
vafc
skunk 2 ecu


what do u think that will put out and is that worth it...


i am more of a allmotor junky than a turbo guy...

[got v-tec?]

right around 200whp 165-170tq

[crabby760]

allrite cool deall thanks for all the info peep this

rite now i just have stock ls with short ram intake and full exhaust

i raced a 03 sentra spec v it has i/h/e no cat and balance shaft removal kit

we ran 3 times all 3 times i put 1 car length... this tells me i have 1 strong ls motor...

[mellowboy]

Yeh man you get the idea on what you want. Now after all that...get it tuned!

And pray that you'll get 200 whp out a b16. Its really hard and i only know ONE that had ever achieved that goal. It was in some magazine. I forgot what its called. I'll find out.

[crxlvr]

it was hci, ive done almost every mod they had also, plus im running a 3200rpm stall convertor, cuz im running an autobox.

[mellowboy]

Yeh that was it. Man keep us updated on that.

high revs and high compression should be able to get b16 over 200whp. there are some 4ag's making around 240hp(at crank?) at around like 11000rpms; 4ag's are 1.6l.
