how much boost can a b20 hold and how much boost can a b18 ls motor hold and what would be a better motor to turbo stock

crxnj

It has nothing to do with boost,,its the power..Both motors have been proven to handle +300whp and take +8000revs..But I would go b18a/b turbo just because it has thicker sleeves then the b20b/z..

Whoa dude, you definetly need to search... I usualy do before ever making a post. It saves time, you get instant multiple results.

Search around, you'll find some good info.

BTW, the B20 actually has thicker sleeves then any other B series block.. Just an overall weaker design.

Its because of the uni-sleeve design right,,? All I know is the b20b/z sleeves are not the best for boost..

ok i got one guy telling me the b18 has bigger sleeves then i got another guy telling me the b20 has bigger sleeves. if the b20 has thicker sleeves how would it be weaker all the motor are made from the same metel.

There was a book I read somewhere about the motor..It was about how honda got the motor to 2.0L ..And how it has thinner walls then the rest of the b-motors,,and on how the b20 has 6mm that seperates each cylinder and the rest of the b-motors have 9mm that seperates each cylinder...Also how the b20 motor was casted different then the rest of the b-motors..

I forget what book it was thogh,,It was from back in the day..

Like someone said before, you need to search. Blaze is correct it was the singular design of the b20 sleeves that made them prone to cracking under the pressure... literally. But yeah, someone should lock this post it's been discussed hundreds of times before... use search

i dont care if its been asked b4 im asking it now

Blaze45

What are you still asking? You got your answer, no need to a jerk about it. Like I said you need to search, people here on HT get asked these question a million times a day and pardon us for being sick of replying to the same posts the same answers over and over when you can take a grand total of 15 seconds out of your day to click on the seach button, click archived, type in LS turbo or B20 turbo. BAM! Instant results and hours of reading for your pleasure.

But since you dont seem to care about anyone but yourself, Ill humor you.

The B20 has a weaker sleeve design then then all other B series motors. (The sleeves are actually thicker then the other B series sleeves but due to simeese design it does make them more prone to cracking.) The LS does not have as much displacement as the B20 and doesnt make as much over all trq. When it comes to producing power, extra displacment is always nice to have and makes for a much better power delivery. Both motors have been rev'd up to 8k+ with the stock bottom end, despite having a not so great rod/stroke ratio. There was a thread a while back on the differences in bore/stroke ratios on the motors which was quite informative, but I cant seem to find the link. As for picking the right size snail, thats really up to you. Depending on where you like your power and what you will be doing with your car will dicatate what snail you should run. Boost from a T-25 @ 15psi will differ largly from a GT45R at 15psi, and chage power delivery, need for proper fueling and traction control. I believe that St00pid tuned a stock block LS to over 400whp and ran a large shot of juice on the motor as well and that motor held togeathor nicely. Some people running B20s havent had the $ to upgrade sleeves, but have $ for rods and pistons and throw em in and have made 400+ whp with good dyno tuning. In the end, it always boils back down to the tuning and how safe and reliable the setup is and how well you maintain it.
Just look at one-fabs 500+hp stock H22 that made over 40 passes on the dyno/track.

thank you sorry about being a jerk but it got u to answer me wit out runing all over the world wide web to find the answer when all along it was in your head

andymangsr94

well i guess im have to go wit the b18 sounds a lil safer but wat do u guys think about a 14b dsm turbo on it. they make turbo manifolds on ebay that lets u put these turbos on the b serise motors. i got a talon so i got all the parts to turbo a b18 i just need the manifold. i want to run 10 psi i figuer since its a small turbo it would spoll up faster then the talon cause of the higher compresstion in the b18 motor. im hopeing to run atleast 220 hp. i was watching the speed channel and i dont remember wat i was watching but they said the rule of thumb about boost is for ever 1 psi u get 10 hp so if thats ture 10 psi to a ls motor and i should run about 240 but i dont no how ture that is so im hopeing 220.

The manifold on ebay you are looking at isnt ss autochrome,xsracing garbage is it? If you want a good cheap reliable manifold check out http://cc-fab.net..Also there is a guy on here that made 234whp with a 14b turbo at 10psi on a sohc vtec motor..

The most important thing is fuel system,,get upgraded fuel pump,bigger injectors,and ecu tuning..Also if you go past 10-11psi youll need a different map sensor..But you said 10psi so no need to worry

No, its not that XS racing manifold , its this one here, tell me what do you think about ithttp://cgi.ebay.com/ebaymotors/Integra-B-Series-DSM-4G63-Turbo-Manifold-B16-B18_W0QQcmdZViewItemQQcategoryZ33742QQitemZ8034168 660QQrdZ1QQsspagenameZWDVW

Negatory, that manifold is trash. Get ahold of cc-fab.net for a manifold.

Stone mountain racing,xs turbo,and ss autochrome are all the same..Those tubular turbo manifolds they make for honda/acura suck..Stay away..Like I said check out cc-fab.net for good cheap manifolds,,

What a ******* asshat!!!! OBTW if you had searched the FI forum you might have found the 100+ page thread about LS Turbo setups............

whats wrong wit the ssac turbo manifolds i dont see anything wrong wit them they look build pretty good to next to that cc **** now that **** looks like garbage but i wouldnt no so let me know wats really good wit the 2 manifolds and dont tell me to ******* search cause i put in ssac turbo manifolds and **** cam up so dont give me that bs search ****

andymangsr94

well looking around i found one thing to help me

You do some research. Search on here and http://www.homemadeturbo.com to get feedback on ccfab.

Because CC-Fab manifolds are made by hand by some experience welders that are well known on HMT. SSAC manifolds are made, I would assume, in a factory with poor quality materials and attention to detail. The difference between CC-Fab and some other companies on HMT that make manifolds and a company like full-rice or something like that is that HMT is a budget community and people there (including me) won't pay $100 to $1000 more for a manifold that does the same job as a cheaper one that will last just as long. You pay for the name brand with companies like that.

On the flip side you more or less get a discount on SSAC manifolds because of the name they've made for themselves. They suck, therefore they are cheap. It is not so with manifolds from companies like CC-Fab or LSD Motorsports, etc.

If you know what you're looking at, you know that CC-Fab and similar manifolds are not pieces of crap. I know you think that since they're not quite chrome enough for the likes of you.

andymangsr94

your right im go wit the cc fab manifold but out of the 4 wats the best, im not buying no ram horns for 400 so forget it lol but the other 3 wats the best thats if u no wat they look like n im sure u do

b20's were designed to be truck motors and were not made to rev high like a b-series motor is...
