I was wondering if an B20 w/ B18C1 Head Hybrid can be safely turbocharged without any problems, if so can I use a Turbo kit (Greddy, Turbonetics), or is it a better/ safer idea to take it to a shop for a custom turbo kit setup?

B20 have thin sleeves so be careful how much u push it. Other then that if u keep the boost low and get a good tune it should be good.

yeah i would sleeve the block before you boost on it just to be safe!

CACIV

yeah, makes sense. Would I also need to reseelve the block if i were to go all motor with a ITR Head? Just want to know my options.

yea. ive seen 12:5:1 motors crack a sleeve. b20 sleeves dont like high cylinder pressures, wether it be na or fi

Those kits would be perfectly fine, keep boost under 12psi and you should be fine. Just a suggestion, if you want to get a kit, get the Drag 3 with the T3/T04E. Tune it correctly, it's no joke...

CACIV

thanks, you all have been a great help. This makes my decsion alot easier

if you have a b20b it'll prolly take more abuse due to lower compression. my old b20b went threw 2 years of a 75 & 100 shot of nitrous and 7 months of 10psi on a POS fmu/safc setup.

a friend of mine is running a 150shot on a stock sleeved built CRvtec w/ 11:1 compression. no problems yet (hondata tuned).

Just keep an eye on it and make sure you play it safe on how much fuel and timing you use. Dont worry about the sleeves until they actualy give you a problem.

B20's

Just get an LS block and throw some forged rods/pistons in it...

Boosted Power

B20 boosted will be fine. Know what you're doing and good tuning will help.

beerbongskickass

It will be fine? Ask all the people that have cracked B20 sleeves (the people that know that they are doing). Good tuning won't change the design of the sleeves, that is why they crack. B20 sleeves are not like other b-series sleeves. Tuning will only get you so far, some people have had good luck, others haven't had good luck. I would rather not risk it, but that's me.

Boosted Power

Whoever said that he was going to be pushing a B20 boosted to its limits. Yes, the sleeves run the risk of cracking because of it being thinner then other b-series. Doesn't mean everyone who is going to turbocharge there b20 is going to push it to its limits.
I have lots of buddies who run b20 stock block with boost or nitrous and never had a problem. It's when you start pushing the motor beyond its limits that you start to break things.

I have respect for you, cause you're pretty well known for your 230whp on your stock d16z6.
I love that.

beerbongskickass

Well what do you consider pushing the limits? If I had a stock b-series motor, won't ever happen, but if I did I would expect at least 300whp. I am guessing the majority of people with boosted b-series motors would like at least that much power as well. I don't think that's pushing the limits on any b-series motor, except a b20 block. Is the extra .2 displacement really worth it? I don't think it is, because it's too easy to just turn the boost up with an LS, b16, b18c, etc... to make up for the displacement.

I dunno, I just think he would be better off with a different block, incase he decides to build his motor in the future. Planning for upgrades right now will save you a lot of money in the long run.

Oh and I am pretty suprised my engine hasn't blown up yet, as hard as I rape it lol...

the only way i would run a b20b block is if it were sleeved. i was gonna do it to my last b20 but got a killer deal on a pre-sleeved ls block. 84.5mm

Couldnt agree more.

beerbongskickass

Speaking of aftermarket sleeves, a b20 block will cost you more money to sleeve than the other b-series blocks because of their sleeve design.

i was quoted the same price by golden eagle to sleeve both an ls and a b20b. I ended up going with darton mid sleeves

Cloner

Golden eagle wanted $700 for sleeving on an LS block but wanted $900 for the b20.Walk in.

Hmm that's weird because I could find a few posts on here by golden eagle that say it will cost more to sleeve the B20. I have also seen posts by exospeed that say they charge a few more bucks as well.

hmm, i guess vince likes me, lol
i might be remembering correctly im not sure. ive had one hell of a headache for the last two days so yea

I have always heard that B20 sleeves are weak and don't like boost, but a buddy of mine used to have a boosted B20/vtec and beat the **** out of it on a daily basis at 16-17 psi . Me personally, I would do ls block, but with a good tuner, B20 is not out of the question .
