| BKS8 |
| Just wondering. I am looking into an engine swap, and i have been looking into the B18A/B and then there are engines with V-TEC. what would be better? Please let me know. |

Either ProDrag guy "pearlywhitetsi" or 'Focusfool" from Midas should be able to do it for you.
They both have real shops. |

its vtec dammit!!
and yes a b18c would be better than a b18a/b....more top end power. wayyyy more. |

Ok, now people telling you that the b18a/b are not a good choice in compaired to a b18c1/c5 should shut the hell up because you didn't even say what kind of car you are planning on building... in some ways the b18a/b is actually better then the vtec versions which are the C series 1, and 5..
Bascially all the engines are honda 1.8 liters. and that is where the 18 comes from. They are all the engines that you find in the integras, which are based on the same chassis as a civic so the engines are a great choice for a swap. Ok now
B18a - Integra LS/RS DOHC NON-VTEC
B18b - Integra SE (I think) also DOHC NON-VTEC
both these engines have 160hp and redline around 6000RPM.. I belive, i have not been in the lower grade integras but I think thats what I read.
B18C1 - Integra GSR - DOHC VTEC
now this engine has around 180Hp, it does this by changing the engine timing.. which is what vtec does. If your Vtec part of your ECU gets fucked this engine will produce the same power as a b18a/b because it won't change the timing.
B18C5 - Integra TYPE R - DOHC VTEC (TYPE R)
This engine is out of a type R so there is more power of course.. these engines push 195hp (approx) but has the highest compression out of all the b18 series engines.
All the people that tell you VTEC is the shit and thats what you want should think befor they talk.. Engines with lower compression work better with turbocharged setups. So the LS/RS/SE engines are actually better for this, also the gearing in the transmissions for the LS/RS/SE are longer, so you actually make more boost for a longer period of time which is better and you will run lower times. If you are planning to run a N/A which stands for Naturaly Aspired engine which means no turbo or supercharger then yes the high compression vtec engines are better.
Actually if you have questions that are more basic please feel free to PM me. I will hook you up with the info =) |

hmm, last time i checked vtec funtions based on a more aggressive cam profile...
and turbo VTEC works fine, in fact, many tuners claim the big cams are quite turbo friendly |

B18B is only 140 Hp.
VTEC is excellent when used with Turbo.
There's nothing Wrong with turboing a GSR. I would actually reccomend turboing a GSR over an LS, when properly Tuned.
A Type R I would agree it is denfinatley to high compression. I would not reccomend turboing this engine |

I have no personal experience to add to this thread,
but here is a link to B series engine specifications.
Enjoy.

edit --
ever consider the B16A?
can anyone say anything about this motor?

I have driven B16's before. they are not very fast. But they are an excellent platform to build on. Parts are abundant.

i didn't read ur posts...sorry if this is a repost
from wat i hear:
ls/vtec engines r good for daily drivin, good low end power
not so good for circuits/high rpm racing (cuz of the pistons?? idunno)
itr/gsr engines r better for prolonged high rpm usage
personally, i would choose the ls/vtec route jus cuz i like low end grunt

who in edmonton can do the LS/VTEC properly... i have yet to see this done on any cars in edmonton.
if you had the money... all motor B18C5 built is fun! but $8000 for engine plus other stuff sounds pricey :( |

Well the LS Vtec is the ultimate Bseries setup IMO. But if you don't build it right they blow to bits. If you boar it out to 2.0 liter you can make some insane numbers with only 6 psi. you can actually use a B20 block and then its all ready a 2.0 liter.
LOWER COMPRESSION IS BETTER FOR TURBOCHARGED SETUPS..
there are professional drag cars that run just a LS engine turboed. I have read a lot of information that says the B16s are actually better for forced induction then a B18c1, supposidly the b18c1 has issues with turbocharged setups and its internal parts not liking the extra strain. As with anything though, treat it good and get all you matainance done and you should be fine. |

definately not a honda specialised here but thsi is just my 2 cents.
Two kinds of frankenstein setups.
LS/Vtec and B20/vtec.
both of them excellent for drag use and I have heard of soem people using them on the track.
Reason they're not good for high rpm and constant WOT usage for circuit is that they lack the proper equipment when compared to the B18C1 and B18C5. From what I hear the LS block does not have the piston oil squirters and such for high rpm usage. Not too sure if thats exactly it but
I believe darkman would be able to shed more light on this subject.
Without the proper ECU setup when turbocharging or supercharging a honda/acura with vtec, I hear the oem computer tends to dump fuel when it senses boost. Obviously this isn;t gonna be very good for performance when you run that rich. This might be a reason why some poeple more often add forced induction on non vtec cars also for the that the B18C1 and C5 probably have a higher compression rating and for the simple issue that getting a vtec equipped Acura/Honda is more often then not harder to get compared to a non vtec car. |

B18C1 doesnt not have extermely high compression.
Any honda ECU "VTEC and Non-VTEC" will pull a CEL when the MAP sensor detects over 3+ volts. this is caused by positive pressure in the manifold. This causes the ECU to go in Limp mode and dump extra fuel and advance the timming.
To bypass this get a missing link, or upgrade to a 3 bar GM map sensor. or get a standalone such as hondata

Try disconnecting the vtec wire from the ecu.. then go for a run past 5200rpm.. its not fun like normal.. its.. well slow |

| And yes.. you have to build up the b18a/b or b20 with things like oil squirters because if you don't it overheats and dies.. but that can be very interesting.. I actually have talked to someone with a 2.0 boared LS/vtec.. he runs about 20PSI and has had the car 2 years I think.. no problems.. then agian he put like 20,000 into the engine so nothing should be going wrong. If you are looking to kick someones ass that is totally not expecting it the car is perfect.. little eg coupe.. but I would guess something like 350-400 HP.. and really low ets.. |

whoa dude. u are wrong many times over. heres a few glaring errors:
1. b18a is from 3rd gen tegs (ls/gs) -130 or 140 hp , b18b is from 4th gen tegs (ls/gs)- 140hp
2. they both redline above 7000rpm...not 6000. my old 92 accord could redline higher than 6000.
3. b18c has 170hp.
4. vtec doesnt change "engine timing". in fact theres no such thing as "engine timing". ure referring to "cam timing" or maybe "ignition timing"...neither of which vtec directly affects. vtec allows for 2 different cam profiles...one for low rpms, one for high. ivtec has variable camshaft phasing as well, which would vary the cam timing.
5. the tranny from the base models can be bolted onto the gsr, its not like the engine and tranny arent interchangeable. |
