Hey guys, I'm wondering what kind of camshafts and cam gear would be an upgrade for a b18b1? I'm looking for good quality brands or maybe even factory HONDA stuff from another engine, just not sure which. What other ways could I build up a N/A motor for more horsepower? Thanks.

 

Go LS/VTEC, best bang for your buck, if you can get the parts cheap, head is the most expensive usually

 

Look into crower 401-403 cams. And any adjustable camshaft really, but then you will need a tune.

 

Yea for the price of new cams you could find a vtec head. What's your budget?

 

I personally don't see the point of doing an all motor LS build. Although some people have been satisfied with their results, the capability of a DD non-VTEC is limited. Your money would be better spent on FI. Don't let people fool you, either, converting to VTEC properly requires more than just a new head.

But if you're determined to go this route Crower makes some good cams for non-VTEC B-series.

 

That's why I asked what his budget was, depending on that I was gonna let him know the proper parts to do an LSV right. If funds are applicable.

 

Oh really now i don't think so about that dude about Ls NA has a limit I'm going to build a all motor Ls and i bet i can bet Lsvs anytime or day like I beat my friends here with their Gsrs, B16as, and a random S2000 lol. Llike my friend dirtyda9 and you posted crower camshafts like 401-403s be great but tuning is mandatory.

 

don't really have a budget...just something affordable to gain a few more horses.

i'm waiting for my exhaust to arrive next wednesday, header's will be coming up the following week. No way am i going FI (might as well get another car) and I don't think I would be doing ls/vtec either because it's too expensive.

I was also thinking of the crower cams like these : http://www.ebay.com/itm/CROWER-INTEG...sories&vxp=mtr

but i'm not sure if they are good. I also researched that cam gears aren't going to give HP, its mostly to tune with the timing and set your power band to your liking.

 

With bigger cams you are going to want adjustable cam gears. And you can build a nice LSVTEC for $1,000 no problem

 

For the price of those cams you could get a vtec head ....

 

Of course LS non-VTEC builds have natural limits for DD. The bottom end is rev-limited, meaning you have to build it to rav high enough to make power. Add to that the poor compression, which can't support very much cam, and the fact that aggressive cams have very poor midrange and below.

And the point I was making about the LSV is that it's not enough to slap on a VTEC head and call it a day. Bottom end work is REQUIRED.

 

Agreed about the bottom end, but you can find used PR3 or P30 pistons for a steal on here, and if you are lucky like me, I found P30's on shotpeened rods with ARP's (sold them to teggyluva). But getting rods shotpeened is around $40, and find used ARP rod bolts. Then some honda main/rod bearings. And a used GSR/ITR oil pump for about $60-$70 and the bottom end is done.

 

Wow will people please stop making lsv debates every time someone asks about building their ls. FFS!

Sure, those cams are 300$, but building an LSV costs way more than that, so everyone just bugger off. Everyone who has ever built one knows you need to put in at least a grand for a reliable one.


Now, back on topic.

I would recommend Crower 62402... why?

Because here are some specs for you:

http://www.crower.com/media/pdf/2008b/98-104.pdf
(page 4 i think for non-vtec)

Basically, the crower 402 has the exact same LIFT as the stock cam (meaning your valvetrain can HANDLE it), but longer duration (that it stays open), thus allowing more air in and out.

By going with anything else, the lift is HIGHER than the stock b18b1 cam lift, meaning you will need to upgrade your valvetrain.

You are on a budget, i would say stick with the 402s, and get cam gears, just like you said. You should also consider getting a tune, since you will be running rich.


And just a tip for those of you who are building lsvtecs, if you really think all you need is a 300$ head, you clearly have no idea what you are talking about. Unfortunately, anyone who wants to build an lsvtec that will last, will rebuild the bottom end completely.

 

No one said its just a head. Plus to run most crower cams you should run higher compression pistons. And to get the most out of those cams you should get a port and polish and valve train. Which in the end, is more than building a reliable LSVTEC.

 

^ word. If your already taking the time and money to do a cam swap RIGHT, might as well go with a vtec head just because its around the same amount of money, and you can make more power. Unless, of course, he wants to stick with the stock head.

 

A stock vtec head will still flow and rev better than a built ls head too

 

So true Dan told me that as well lol but p&p and a IM the Ls head be ok it will flow like a stock vtec head or a lil more. I do need higher comp pistons so the crower cams work good and a valvetrain right again bro. That's what my build will be about this dispute about Ls all-motor lol.

 

Oh about that of the rev-limit I found a way u can rev a Ls higher by getting a gsr crank in it. I'm building a Ls all-motor project and i'm going to have a good compression with my Ls cause I'll be having p30 pistons in my block(thanks to DirtyDA9) cause I'll be getting those crower cams. You have 2 have a high comp so they work fully.

 

Lots of people on this forum have B18Bs with Crower 403s and they like them a lot. It's just important to realize that you're doing bottom end work for cams that are similar in profile and performance to GS-R secondary profiles. So max whp is similar to max whp for a boltons GS-R. I don't know if you can get much above 160 whp on a 1.8L B18B build without doing something really extreme.

But if you are already doing bottom end work you can get a B18C1 head with ITR cams for about the same cost as new Crowers, and then you're getting higher performance and with the potential of 200+ whp with more aggressive VTEC cams in the future. Not that you shouldn't do a non-VTEC build, because many people that have them love them, but you should at least be aware of the options.

 

Yea a full P&P and portmatch the aftermarket intake manifold and header, it will flow as good as a vtec head stock, but you just have one big cam in there, vtec is the best of both worlds, small cam for bottom end, big cam for top end. And you already got my P30's so you don't have to worry about compression

 

Oh ok thanks tho dude but I've seen B18bs with no vtec heads reach close to 180whp+ and more but they did work full p&p Ls head,IM, full valvetrain, crower 405's high comp pistons rocking Gsr's, lsv. I had a full gsr long block sold it, B16a head sold it cause I want to do a non vtec build show people u don't really need vtec to be a fast N/A b series beast and don't want to try vtec yet. To tell u the truth tho lsv is on my mind but the crower cams as well for the Ls/b20 head!!! lol

 

Yeah I know compression isn't in my mind thanks to u bro just what to do with top end? gsr head or built B20 head?. I'd like the B20 head more to prove a point to people tho.

 

Lol well then you gotta think, would you rather prove a point, or have more fun driving it? VTEC = more fun with those high rev's.

 

I know can't decide but I'll just prove a point, besides I already have this non vtec head and I love how the crower cams sound when their in the non vtec heads almost sounds like if its hitting vtec. Also when I was on CL i found gsr heads go only 400 to 600!! heck no I sold my gsr engine for 700 with bad rings.

 

I just got into the jdm scene with a dc4... before i had a 454 cupercharged.
but my question is how to get a good mid and high end power. ive been woundering if cams or anything up to like 1000$
