b18b? 1995 gsi engine

[farkew]

i am unsure of the engine code it is the non vtec one obviously ummmm i was wondering has anyone done a port polish on one of these????

if so what power gains were made???

Has anyone put aftermarket cams in these engines even a regrind?

Throttlebody upgrade???

He is just looking for more power without going turbo or vtec?????

[locote]

i will be doin all those mods later this year:) let u know how i go

[spardikis]

i have heard that a b18c/b16a (vtec head) has better flow qualitys.....but i am not sure if it is really the case. mabey someone can confirm it?

[locote]

yes it flows alot better

[farkew]

what would you assume a b16a head would be worth??? and how much modification would need to be done??

[EGB16A]

what would you assume a b16a head would be worth??? and how much modification would need to be done??

jdm yard had a complete reconditioned head, with new everything and CTR cams for $1700-1800 from memory.

however, i'd imagine a secondhand b16 head would be worth around the $500 mark.... thats a guestimate, how ever i have seen a b16a head in the trading post for $300 (complete head)

as for the rest of the modifications needed, speak to tinkerbell, he is the hybrid god around here :D

[farkew]

running a vtec head then that requires ecu??? and loom and the whole bit???

[IN73GZ]

search my frend, this has been covered before. Many people opt to get a b16a head coz it has more flow than a b18c head and they put it on the b18b bottom end. this is called a "poor mans type R".
i believe how much $$$ threads are not allowed either.

[locote]

running a vtec head then that requires ecu??? and loom and the whole bit???


YES you will need a new ECU since yours isnt designed to run a vtec motor,
YES you will need to run a wire from the vtec solenoid to your ECU, so vtec can be activated.
if i was to get that sort of work done id get a complete recon head, ECU and LOOM.
and get some work done to head (porting), get aftermarket valve gear, and cams since your head will be off you can do all the work your self,
rather than 3months down the track when you HAVE THE NEED FOR MORE POWER and have to take the head off again.

[locote]

mate if u want vtec y not just sell the car and get a vtir or ITR???
i was in your same boat.
for what a gsi cost and what ur planning to spend just doesnt make it worth all the effort and $$.

and dont forget that your bottom end is not designed to be revved to 8000+rpm like a b18c.

if you just want a vtec motor to fit into your Tegra then u can pick up a B16a fairly cheaply, it might be a bit slower than with the b18b but once u do a few mods to the b16a im sure itll go hard and youl have vtec

[spardikis]

lol i'm selling a b18c head and cams!!!!! lol :)

[locote]

Why is that???

B16 on ebay

[spardikis]

im selling the b18c head coz i did a poor mans type r build up and used a b16a head.....I was left with the b18c head from the vtir motor. it could be an option for the bottom end he has! but i dont recomend the ls/vtec as its r.s ratio is shit.

[locote]

so u used the b16a head on a b18c block???

[spardikis]

yep with ctr pistons...its mean

[locote]

sweet it would be!!! he he
how much that set u back if u dont mind me asking.
and what Hp you puting down at tyres

[spardikis]

i have just brought an itr intake....$130.00 about to put it on.
engine was mint condition $1300.00 and i fully rebuilt it with ctr pistons $450.00
pr3 head $250.00
I did all the work, reconed the lot, micrometed new bearings $400ish ....head gasket $80.00 timing belt......you all that stuff.....chipped itr ecu.

just slowley upgrading the intake, cams and extrtactors.
had it on the dyno - just done 1000kms, with my exhaust silencer stuck in the end of the exhaust....did 90kw untuned just put togeter running advanced. the mercury motor sport guys in brisbane reckon it would easy make an itr power, it just ran out of air at 7000rpm and stopped making power.That was because of a bad intake manifold extractors and t.b. which were all from a b16a. The biggest let down is the long range gear box.

[locote]

nice price for the b18.
was that the intake mani in ebay???
i saw it yesterday.
you should make crapload more power once u get it all sorted, im making 95kw in my with a safc2 used for tunning wich is a crap tunning tool anyways.
whats ur power goal at front wheels????

[spardikis]

yeah intake was on ebay

110kw at wheels i reckon id be happy with. Might get more with a tune

[locote]

yeah thats my goal to.
id like to run 13s at drags but ill prob need nitrous for that:)

[spardikis]

your ride loks scaryily the same as mine!!! just got some roh drift r 17" 7 spokers too. they look mad. anyway, we should probably be trying to help this dude make a good decision with his engine pick!

my advice is read all the shit you can, ask every question possible and make a decision based on what you think will work for you and your budget. DO NOT SKIMP ANYTHING. Hondas are very precise, that when done well make great power and reliability. my advice is keep your b18b engine and do intake exhaust and headers....

if thats not enough, do a poor mans type r-its great fun! good luck!

[locote]

ha ha, urs green too???
i took those 17s off 20kg each
got a set of 15s 12kgs each.
still got heaps to do to my but.
B18B with some 403 or 404 crowers and some serious compresion should kick ass.
ppl in US are making 160+hp with them and running 13s
and it wont cost ya a new motor bro!!!

[Weq]

its called an LS/VTEC. plenty of info on here, honda-tech and google about them. very good upgrade imo.

[KB]

Keep the B18B as is. Crower make Sick cams for the B18B increase 24+Hp with ecu tuning. Add on basic bolt ons and you dont need VTEC you have all motor Pig DOG!

[locote]

whats ur best run at the motorplex KB??
ur civic vtec???

[farkew]

i have a type r ex protek car i am asking 4 a friend i dont think he has the dollars to buy a vtec one.... i will c how we go with pp heads bigger throttle body and cams i will keep u guys posted

[spardikis]

the ls/vtec or frankinstien are very powerful, but they lack the ability to rev highly safely (with out alot of money throwen into the bottom end), which leaves them with no real use for vtec. The b18b has longer con rods that make a high r.s (rod stroke) ratio and doesnt have oil reliefe valves either. the bores tend to warp oval, through too much stress from high revs.and i think the crank isnt ballanced like the vtec b16a or b18c too. make sure you read the pros and cons of the build.

[KB]

whats ur best run at the motorplex KB??
ur civic vtec???

15.3 With I/H/E in my SOHC VTEC.

Am gonna head down when my new ecu comes so i can test out this new bloody cam!

[locote]

went again tonight it so frustrating not having the power to make up for the lack of take off!!!
i feel like goin turbo but i dont know if itll be worth it.

[barefootbonzai]

you know you wanna come to brisbane and put in a real engine!!!!!

[locote]

hahahha.
the trip there would cost a fortune!!!!
looking at 3 weeks in total hahah

[spardikis]

if your real desperate nz is really the only place to do it....that shit is crazy cheap over there
