Boosting a b20?

[blacknightteg]

I am wondering if it is a good thing to do. i am in the market to swap my engine out and ive narrowed down my options to either getting another ls and boosting it or getting a b20 and boosting it. now this is my daily, so im not wanting much power. i would like to do a b20 if i can. but i have heard mixed reviews on doing it. so if you have done it before, please let me know your opinion!

b20 on 8 lbs FTMFW

[blacknightteg]

thats what i keep hearing. i think its what i am going to end up doing.

[1CleanEg]

damn i was just about to make a thread about this. Seems like everybody is tellin me to do the jdm b20 on 8lbs too.

[blacknightteg]

yeah im gunna try to get a b20z from NAD

[1CleanEg]

good luck with it man, i should be swapped by next month and boosted by hopefully august

[Decepticon™]

yeah im gunna try to get a b20z from NAD


good luck with that


when i got B20b they had no Zs but that was awhile ago.

if your planning to boost anyway just get the b20b it has lower compression then the Z like the Z is like 9.2 or some along that line, anf the B is 8.8


well either what B20 ftw i love mine....
BTW what tranny are you planning to run????

[seanrg1116]

b20 have thin sleeves just to let you know.

LS is better for boost but its your decision in the end.

Boost is fun..............................Just be ready to spend some $$$$ on a good tune

[blacknightteg]

i have been talking to people and i think i may go with a b16. either that or a gsr. i am going to have to look for a kit that i can get. i dont want a lot of power so i dont want some mad crazy custom kit thats gunna cost me like 3 thousand dollars.

I just upgraded from a LS w/gsr tranny in a Hatch to a 98 civic coupe with a turbo GSR and it is so much fun. But I will miss the low end torque that is in the LS.

If you can wait and save a turbo GSR will put smiles on ur face

[big mac]

i would go ls before b20. i have a boosted ls v in my car and i would recomend it to anyone

[blacknightteg]

i honestly dont want to. im looking for decent power on a buget and to the b20 seems the best root

[Decepticon™]

Yea b20 has thin walls...that doesnt mean it cant safely handle some boost. You just gotta be aware of what your doing, and dont go boostin like 20 lbs on stock b20 bottom end.

na i definetly wont be doing that. its my daily driver and the majority of my driving is either highway back and forth two days a week or to work. so it would be low always. i have no intention of doing anything crazy. if i do more research and find out it might not be a good idea to do it. then ill probably just buy a new ls long block and boost it.

You should talk to BoostedB20 (??? i think thats his SN) but he has a b20 on boost in a hatch. He sounds like he know his shit and plus hes rockin the build you want. Ill try to find the thread he made on his hatch and ill get back to you....

[WTF?]

so what does the b20 on 8lbs usualy put out?

[1CleanEg]

i have heard 8 lbs is good for a little over 200hp

[vancem3m3]

LS lasted lasted me the long on boost ..gsr pop b20/vtec pop

[blacknightteg]

decepticon: yeah man do. it would be nice to read up on it or talk to him about it and see. cause im really at a loss between the two options. both of are good in my eyes.

[NOCLUE]

i will keep poping in i like were this thread is going

[blacknightteg]

im really wanting to do the b20 but im just concerned on how safe it is.

B20B4 on 8psi = 258whp! 8.41 1/8 mile times and is still a running engine. i swapped for an ls vtec for higher boost. they have thin cylinder walls so for lower compression and reliability with boost use a b20b4. if going na b20z for the higher compression. also since there not that high get some arp rod bolts for the added force of the heavier 84mm pistons and be sure to notch the intake valve pockets if using vtec head. i have a b20 b4 with a small crack in #1 sleeve still runs great on 8psi when i pulled out, but with 4 new pistons already notched and arp rod bolts cheap.if you need any parts pm me.

[SPOOLIN]

b20 ftl....b18 for the win, better sleeve design for being more forgiving. on a side note i have a b16a long block for sale. :)

[Hondatwin23]

A b20 dart block and all your problem are in the bag, no more thin walls

[Captain-Obvious™]

do not put a b16 in that integra

[blacknightteg]

lol. i wont. i really want to do a b20, but i just dont want any problems. keep in mind this will be my daily driver, it will not be raced or anything of that nature. atleast not until i can get another daily driver. so the least amount of wear and tear possible is better. i will want to boost it, regardless of what engine i get. i just need to make sure that if i stay stock internal wise, i will be ok. cause i dont plan on doing anything to the internals, atleast not anytime soon.

dont worry daniel, i wont. lol. if anything a gsr head will go on it. but i doubt that to.

[Captain-Obvious™]

:goodjob:

[blacknightteg]

i dont know wtf im going to do. lol. i procrastinate way to much.

If your on a budget the b18b(230whp=reliable), but if you have a lil extra cash get a b18c(260whp=reliable). Get it tuned.

[DriVaH]

b20b + b61 head + ARP studs + xxx turbo at xx PSI and TUNE= win...i had a setup in a hatch for 2 years.. 534WHP @ 25 PSI...plenty of fun... check these guys out http://www.lvracingscene.com/forum/showthread.php?t=48877

im not gunna do a b18c. the options i am considering are either a b20 or LS

i dont want that type of power. its not a track or drag car its a dd. ill worry about havin that much power when i actually track it

[DriVaH]

i dont want that type of power. its not a track or drag car its a dd. ill worry about havin that much power when i actually track iti was just saying that with a good tune you would be ok with stock internals... and i dd'ed mine...staying with stock internals makes the build cheaper, and the tune made ir reliable

[blacknightteg]

yeah i know. i just dont need that type of power.

[AV8ter]

Broseph? Why not boost the ls engine at 8-9psi and leave it that way if it floats your boat for a quick reliable daily driver? If you aint diggin it throw the b20b in and go get it retuned........

stock b20 on 13psi

b20 are nice if you just take care of them!!

[Master Shake]

just remember the b20 sleeves are weak and have a higher chance of cracking.

boosting, i'd go ls waaaay before b20.
all motor, b20 before ls.

^^^^but fun!

[joeblo]

boosting the b20 is no problem but the 84mm sleeves can be a factor. there is a wealth of info out there on this stuff. just do your research. and of course tuning is key. either motor could blow up w/o the right tuning. you can definitely get 200 ft/lbs of torque on a stock block with the LS-from my experience. just my 2cents.

[turbob20]

as i said stock internal b20 with gsr head made 258whp for 5 years daily driven on 8 psi with nothing more than arp rod bolt for added durability on the stock bigger and slightly heavier 84mm pistons. the ls boosted is very reliable. b20b4 will only go 8psi. when i tried 10 thats what cracked my sleeve.the b20 with b20 or ls head will make approx 220-240 give or take depending on a chipped and tuned ecu and the tunner. no tune with a b20 and boost is a bad combination. so if tunning is out of the question an ls will last longer with say a crappy fmu, but i went with ls and the tune. but b20 on 8psi will last and have a little more torque but no more than 8psi.

[1CleanEg]

this has been a very helpful thread. good job

[Decepticon™]

well im going b20 boost with a greddy kit. it should be done by this weekend and tuned some time shortly after so let you know how it goes.......
