hey guys,

just wanted to know, how much psi can these two engines handle ..while being SAFE that is,

b16a2
b18gsr

my decision on the swap ... depends on this question of which motor can handle more psi being SAFE..... and hence give me more power....

since i dont plan to change the interns and do bottom work!

and ya....its goin in a civic
cheers

I think 7psi should be ok, just run a higher octane fuel.

mx621

has nothing to do with boost, its just a reference. its how much torque/hp can the stock internals handle. thats the question to ask. many people have tuned b series motors (exept b20) to 350+ wheel all stock internals. its all in the tune. 300whp is a good hp number to stop at on all oem internals, for mostly daily driver car.

irtaash

ahaan thanks for clarifying that

yeah am faiarly new at this...

so around 300hp shud be safe? with gud tunning

but suggest me the best engine b16a or gsr?..... less commprssion to more displacement....

mx621

gsr will make more torque from the longer stroke, and has a better tranny for boost. 300hp is a number if tuned by a professional tuner, on a good quality turbo setup. not on some safc hack, or and other kind of ghetto tuning

i just tuned my complete stock block gsr on 10 pounds the other night, made 306hp 220tq, but all depends in the tuner, i know my tuner knows how to do his job good luck to ya

b16a2 should be safe on 5 psi if you know how to take care of a car

What did you tune it with?

What is considered a good tuning system for a stock internals turbo setup at around 300whp? Full-on Hondata, or can you get by with something less like Chrome?

this tells me i shud prefer gsr over b16a..... those are some decent numbers... ya hopefully i will get it tuned from a gud pro....
gdluck to u to man!

cheers

well the GSR willl be better for boost, I'm an N/A fan so I'd probably do the B16, but since u want boost, I say go with the GSR, max u can run on that? I'm not sure, safely I can probably say 8lbs on stock internals, I wouldn't judge it by horsepower, u can throw down 300hp at the wheels and throw a rod the next day, on stock internals, might wanna keep the PSI relatively low for a daily driver

i use hondata, youll gain more tq with a gsr, i saw a stock b16 dyno 10 pounds, made 270hp and 176tq

bdw am talking about the jdm spec b16 and b18 gsr...since i would be swapping the jdm ones

with 10:4:1 & 10:6:1(gsr) compression ratios....

hondaeg8

just get the GSR motor.

with the right turbo set up, you can make 300 or a little over 300whp on 10psi with a good tune.


oh yeah, the GSR isn't the "BEST" tranny for boost for whoever made that comment about the GSR has the best tranny for boost.

im running my stock b16 at 10 psi 60-1 turbo, 270 whp and still strong

TuwboBuddy

There have been a number of both pushing 300whp, it's just a question of for how long. I've seen it done though with a good, experienced tuner

irtaash

yeah i well i suppose around 7 to 8 pounds wud be a safe bet ....with good tune shud give me around 260-280 hp

hondaeg8

i'm running 7psi on my GSR motor in an eg hatch.

pulls pretty strong. don't know how much power i'm making though.

irtaash

bdw i am always mentioning the jdm spec ones....since i guess jdm's are the ones i am gonna be getting in my part of the world......

upon comparison i figured that.... Although all USDM spec engines have slightly less hp..... but also have less compression !

jdm b16a 10:4:1
jdm GSR 10:6:1

So are the usdm ones better for boost on stock interns? by having less compression.... or the difference is not all that big......and the jdm gsr is still the right choice?

cheers

hondaeg8

dude, people have already gave you their opinions. they know you said JDM motors and we know the compression numbers. you have also mentioned about it a couple of times already.


the GSR motor is a BETTER motor to boost on stock internals. it comes with more power and you'll make more tq than you would with the b16 motor. its a 1.8l motor and is a good motor to run.

if you CAN afford the GSR motor , then get it............ ENOUGH SAID!!

if you can't afford one, then get the b16 motor

its not that hard to decide.

irtaash

yeah i figured i was kinda repeating things alot..... :S

prolly cauz of my first ever build.... so excuse me for that

yeah gsr is it then... thanks to all...

wud post up when am done with it....

cheers
