You mean nothing happens? Lol, except the timing belt snapping. Non interference engines ftw.

Nice. Now much HP you get out that engine?

thanks guys..

piro my side skirts were made here in colombia

antdx316 i´m just using a programable ecu called Megasiquirt 1 Extra, my car have manual transmission, and it can hold even 23psi

the final speed was 109 milles, and my woo have 248whp at dynoje

248bhp it seems :P

I just can't believe it

But ... You motivate me to do the same thing with this engine

maybe I'll buy second Nexia

Anyway; I still claim, that it won't last a minute ;P With this boost ofcourse

Could You show the Dyno graph?

i am begining to think that the "7 to 8 psi on stock internals" is underrated... we have a member - Klonek AFAIR - running 12 PSi on stock internals on his 2.0 nubira wagon... we were running 9 PSI on the 2.0 nubira sedan.

Generally speaking I thought that most stock cast rods were the biggest weak point (at least that's what Honda people around here say) and usually could only handle around 200 hp? which was why most people played it safe with 7 or 8 psi and maybe 180 hp?

And if You could, please tell me what kind of fuel are you running?

because hondas do over 300-400+hp with just 6-8 psi

there r people doing 24psi on stock internals on other cars and the car being totally fine as a daily driver for years

im pretty sure the stereotype for 6psi is about max on stock internals is wrong because the start of the import boosting era was started by honda owners

Yes the stock rods are weaker than getting steel ones made up, from like, mahle or eagle [i think?] but as gse_turbo told me, it's not usually the rods that go, it's the rod bolts. And when they go, ofc it's gonna fuck up the rod as it'll just be hanging there, getitng beat about inside the chamber/bottom end. I didnt know this until he told me, but a lot of the time when you hear of people bending rods or throwing rods outta the block it's because the rod bolts give and as said there, they get fucked about inside the chambers/bottom end.

Sorry but i don't think that's really a valid point again... Anyone getting over 300bhp with around 8psi in a honda powered car, will have to be with the 2.0 or 2.2vtec. No way will you get near that power with the 1.6 16v vtec engines. 8psi+other mods, maybe... but not only boosting 8psi alone.. The oly reason those 2.2's get over 300bhp so easy is because of what they are to start off with, they're over 200bhp n/a.

Also depends how you drive the motor, you could have a car set up to boost 30psi and never push it past like 10psi. Constantly on boost will obviously take it's toll on any engine.

im pretty sure the stereotype for 6psi is about max on stock internals is wrong because the start of the import boosting era was started by honda owners

The reason there's such comotion about max boost on stock engines between 6 and say 10 psi is because thats when talking about running a turbo on a car that's not meant for a turbo.

By lowering the compression, practically any car can be turbo'd [to an extent] and run at 6psi very safely. Running boost over say, 10psi, on what's refered to as a stock engine, isnt wise. People throw these terms about very loosly and so many people pick it up so differently. The reason boosting over, for example, 10psi on a STOCK engine is not conciderd safe, is to do with fueling and the engine management sytems. Yes, the INTERNALS might be able to handle that type of boost, but only if set up properly, with the right fueling. Otherwise it'll just detonate and end up breaking something.

Running a car with a lotta boost on an aftermarket programmableecu, or a thing like megasquirt lets you pump shitloads more fuel in throughout the rev range, meaning, the car won't run lean at higher rpms, preventing detonation.

To just summarise that a little, it looks a bit messy;

Typically, when people say it's not safe running a standard engine, stock internals, over say 10 psi, they mean, a STANDARD engine. Everything except maybe the compression ratio. The ecu won't be able to read all that extra compressed air getting shoved in usually, and so, won't compensate with extra fuel as either the ecu won't read it, or the injectors might not be able to cope with it.

However, with the right setup, low compression ratio, suitable injectors and fueling, maybe a dualstage fpr or fifth injector, and a standalone engine management system, it is very easily possible to run over 10psi safely. By safely i mean without detonation, and without risking damaging internals due to the car firing before it's supposed to, due to running lean. [too much air not enough fuel].

Ofc running high amounts of boost in an engine with standard internals won't be as safe as running the same setup, only with stronger rods/pistons/rod bolts. But hey, it's still doable. And i know a fella who ran 12psi all day long with a 2.0 8v Vauxhall engine [c20ne] for well over a year and nothing at all went wrong with it. All he had was a fifth injector, different injectors and 2 headgaskets to reduce the CR a bit more.

jejejejej ok go ahead buy a second nexia and try doing what im talking about....... the secret is low compression ratio, fuel injectors of 550cc, walbro fuel pump and a programable ecu like mega squirt, haltech, AEM or what ever you want. I have to sacan dyno graph, im gonna posted later, also i´m usig a kind of gasoline called ETILICA in my country, the gas of airplanes......

here is my time

Looks good m8. Me and a friend threw out on of those 8v engines. Didnt know the comp was so low standard. WIsh i hadda read the engine code.

Ah well. I like your dash cluster. Where'd you get the white dials? ANd what's it look like in the dark?

sry to burst ur bubble but there r many D16 SOHC Stock Internals which is 1.6L that do that much hp search youtube

what are the model & specs of those injectors? Whats the flow rate?
From which car? Any GM Part number?

I am also looking for uprated injectors to support my upgrades.

How many of them run only a turbo at 6-8psi, and no other modification, that you know off, for a fact. I could put a vid of a car driving past me on youtube and claim it to be 300bhp, doesnt mean it is.
