i have a b18b1 wat can you guys tell me bout that motor. its non vtec id like to get a vtec head but not sure exactly wat to get should i stick with a b18 or should i get b20

 

there is no b20 vtec head. do some searches man, you ask the worst questions on here.

 

Seriously man go do some research before you post on here. All the stuff you post about has been covered a million times. There's already a plethora of information about LS/vtec engines all over the Internet. Don't expect people to spoon feed you information. And learn how to spell.

 

i thought these forums were supposed to help you but all i get is a bunch ******** response wtf fml

 

People just get tired of seeing threads asking questions that have already been asked a million times before. If you searched you could find the answer to this question pretty easily. There also aren't easy answers -- what to do depends on your preferences, budget, and goals. If you have more specific questions you'll find people are more willing to help you.

 

******* question=******* responses

 

i appreciate your help gangar i just enrolled in uti ill be going to boston in a few months so i wont need any help other than an opinion on a color of something

 

UTI isn't going to teach you **** about LSVTEC setups or technical questions about modding/tuning a car, or anything like that. BTW, UTI sucks. LOL at how you think after you go to uti you are going to know everything you need to know. ahah get real.

 

UTI! that must suck if your going all the way to boston to get a uti. your into some kinky stuff.

Come on guys stop bashin him i agree bro that was kinda dumb....u may not no... but hav u heard of google and the honda tech search bar?

As for the b18b1 its a (correct me if im wrong this is off my knowledge) 150hp engine non-vtec ...its a b18a1 with diff cams air box and cats .To make it vtec u'll need a b16 or a b18c1/c5 vtec head. the b16 comes from a honda civic and can be found for 300-400 bucks at a junk yard near you and are pretty quick........the b18s vtec come from an acura integra gsr or type-r..more expesive more power... any there are more on this topic here--https://honda-tech.com/forums/showthread.php?t=1812388 as well as here-https://honda-tech.com/forums/all-motor-naturally-aspirated-44/how-build-%22reliable%22-lsvtec-b20vtec-1676914/

 

 

have fun paying $20k to learn how to change oil

I went to ATC in Exton and met kids that went to UTI in Exton, and they said they only spend friday in the shop the rest of the week is in the class room taking notes and reading, and that most of the engines and stuff they work on are velcro'd together.

 

B18b1 is a 142hp stock. A b18c5 is the top choice and dollar for a vtec head. The next best is actually the b16 head as it has the same characteristics as the c5 but is made for the smaller b16. The b18c1 head is your cheapest bet and is the least favorite of the heads to use as compared to the other two mentioned before hand. If I had another ls/vtec engine I would have the b16 head over the gsr head anyday.

 

lol wut?

 

Search it. I'm sure almost everyone out there will agree with me that the rankings for a ls/vtec head goes as followed: b18c5, b16, b18c1. This is with all stock internals and not speaking of upgrades.

 

^^ not really...

To clarify:

The B16 and ITR (B18C5) head start off life identically. The B18C5 head has a very mild port job on the intake side. Nothing to justify much of a price hike.

The B18 is a bit different, with a combustion chamber design that lends a slightly higher compression ratio in addition to quench pads to resist detonation.

ITR head excepted, the B18 and B16 have VERY similar flow characteristics. The B16 has a negligibly better top end traded for a negligibly worse mid-rpm flow. Either head when ported is a perfectly acceptable head for any B-series build.

My personal preference is for B18 -- better compression and quench pads to help defeat detonation. Plus I like the idea of a more midrange friendly head although functionally it doesn't matter. Most people will tell you that there is functionally no difference between B18 and B16 heads, so you should go with whatever you can get cheapest. That's probably the best advice you can follow. Certainly head choice is never viewed as a limiting factor in builds...

There may be a slight advantage to the B16 in the sense that some aftermarket intake manifolds bolt up to it better (old style Skunk2 e.g.). Mostly that's a non-issue, however, as newer casts and better designs from other companies (like Edelbrock) have solved that problem. On the other hand the GS-R manifold is quite a good manifold for many low-moderate all motor builds, and it can only bolt to the B18 head.

Of course if you're talking about COMPLETE heads it's a different story -- ITR heads come with the obviously superior ITR cams. B16 heads come with the obviously inferior B16 Civic Si cams. B18 splits the difference. But you have to pay for what you get.

People just like the B16 because of the sex appeal they get from being on the Type R. Yet it wasn't an engineering decision -- Honda simply had a surplus of B16 heads when they designed the TypeR, so it was done to keep costs in check.

If you had to rank complete heads it would be ITR>B18>B16, but the ITR head probably isn't worth the cost.

Ranking just the heads without the valvetrain would be ITR>B18=B16 by most reckoning. Again the ITR struggles to justify it's price.

 

i am disappointed.
