wanna turbo my car, stock long block nothing special how much could i boost and could i boost more with a block guard, and how many pound should i boost

the engine wont break because of different psi, itll break from having too much power for the stock guts and components to handle. a good boost is usually around 10HP for every 1psi of boost. i wouldn't push it hard past 5 or 6 psi, even then you're still risking breakage. and it will probably just run like *** crack without being tuned or having upgraded fuel system components at the least.

Save up money. Do research. Do it right and build the whole thing right.

i would build your bottom end before you boost it ot be safe

Well the stock honda pistons have weak a$$ ring lands and will break quickly under boost conditions, I have seen some break on as little as 3psi with a good tune. Not saying that all will break at 3psi but added pressure on the rings will take it's toll on stock pistons. So I would do like the 2 guys b4 me said and at the least build the bottom end to hold some power. There is more behind the design of forged pistons & rods then just better material used.

x4 bajillion, there is no better advice for you right now until you research and come up with a more dignified goal.

Stock motor i would shoot for 250-275whp at most, which is plenty.

civicr87111, freak things do happen but don't scare the OP, i have also see the wastegate line blow off causing severe overboost and everything was fine.

I also saw a wastegate line blow off of a 240sx with an SR20 swap on the dyno and it made 688whp on the stock motor, granted it blew up later. but that should say something if that happened and a nissan was still breathing.

im running a completely stock b16 in my em1, tuned to around 9-10psi, making 270 whp 180 tq. with small *** exhaust.

research is going to be the biggest key for you in this mod.
first when you boost you dont set goals on PSI, you set it off hp goals. defferent size turbos all have different characteristics as to how your car will make power. The common setup for your build would be a t3/t4 .54ish trim turbo. 8-10psi with a good tune will get you in the 285-300whp range which is a good number to be safe on a stock block. i am also selling that size turbo let me know if your looking.

dont get a block guard, they are a waste and cause extra heat... and constrict coolant flow.

^^^ and how long have you been running that? You must have a damn good tune if you've still got stock fuel system. There was a guy on here about a year ago with a B18c5 putting down 630whp with stock sleeves, so it can be done...just not reccomended at all.

93egSLEEPER

I have been running my LSV setup on 15psi for almost a a year now making 340whp 260tq on a all OEM build. only fuel upgrades i made are a walbro 255 fuel pump and precision 680 injectors.

on the same note my buddy has a vitara setup making 615whp on stock sleeves. its all in the tune... and a bit of luck.

Lol I meant to the guy above you, you just slipped one before I did(that's what she said)

roadsqueegy95

ive been running like that since summer. all ive done the the fuel system was walbro 255 fuel pump and 525 injectors

so i guess not completely stock, was refurring to stock internals

brown82

Stock a B16 can handle anywhere between 8-12 psi safely. it works fine but if I were you Id do some research and build up internals then add the turbo kit, itll only make it safer if u wanna go with higher boost

joelmatt89

this...for some reason there is this huge group of people on here that say you get unreliable if you go above 5-6psi. Plenty of guys are running boosted b16s on stock internals making 300whp for years. Go to the forced induction forum there is much better info in there then you will get here. It is all in the tune, beside a quality setup the tune is the most important thing.

civic_r87111

To all the guys running stock pistons, what is ur cylinder pressures (compression test #'s) as of right now? I'm curious to know for comparison, I guess I should ask what was it when the engine was stock and what is it now?

roadsqueegy95

dont got by psi. there is no "safe" psi level! its the amount of power that will blow your motor. 10 psi on my 57 trim is different then say a small 16g. so dont go by psi go by hp.

93egSLEEPER

i hear an echo in this thread. ( i mentioned this above) to say there is no safe level of PSI is pushing it. it doesnt matter what size turbo you run, if you wanna run 35psi on a stock motor its too much. yes that is a BIG stretch, but there is definately a safe PSI relative to turbo size. both of those determine how much power you make which is often defined by everyone else because its easier.

Coolero

i wanna max out around 240- 250 nothing specail...

joelmatt89

Then there is no need to upgrade your internals unless the engine isn't in good shape. How many miles are on the engine.

bencivic

def. you need to change out the internals cause i turbod my old D15 with some stock internals and i blew my engine in about a week stupid decision on my part so def. take precaution when doing it and change out the internals and i was running 8 psi on my D15 so after all that happend i swapped that out and got a B16 and ive been wanting to turbo it aswell but dont have the money now and im not ganna do it until i can do it with all the best stuff and guarantee i wont have another blow engine haha

joelmatt89

Wow this is the typical reply. First off you are talking about two different engines. Secondly if it blew that quickly the engine was either in bad shape to start off with, or you got an awful tune etc. It is a proven fact that you can run a b16 with 10 psi making 300 whp with stock internal for years and it will be as reliable as turboed engines come. Just because you swap out internals doesn't mean it will be any more reliable, you still need a good tune. There are way more things than just internals that make it reliable.

OP do the research yourself don't try to get quick answers cause the quick answers tend to be the wrong ones.

completely disregard everything above ^

LMAO
b16>d15
Incase you haven't seen the d series pencil thin rods you won't go pass 220 whp and be reliable. A b16 stock will be able to do this and be quite reliable with a nice tune. You sir are comparing 2 diff engine classes it just doesn't work.
