My friend has a 94 or 95 civic running a GSR on 8 lbs of boost. Fast as hell, when it is running. He just blew a head gasket a while back. Before that his header got a little too hot, and the weld holding his BOV got weak and caused it to fall off. Nothing a little extra bracing and a stronger weld can't fix. Then again he does race this car hard rregularly. It is also his daily driver, even with only a roll cage, guages, racing seats and harnesses for an interior. No A/C either.

Blitz made a turbo kit for the Toyota Prius. It is limited to 6 lbs. because the the Prius engine is already running 13.0:1 compression. With exhaust and other mods, power went from 76hp and 82 ft-lb at the crank to 123.8 hp and 144.7 lb-ft at the wheels.

I know 2 contradicting stories, but that is what I have seen.

 

um ok, as i said before, "THEY CAN BE BOOSTED". that is the street s/c untunned from comptech and they look about right. they also offer the race s/c that gives out better #'s.

 

You can boost a high compression motor but it must be tuned right. You can always ad more boost to a lower compression motor. This is just comin knowledge. I think we are arguing about semantics.

 

how many horses do you think the ss/sc puts out? it's only a s/c and it's the street version.

 

DC the LSJ was built for forced induction. Destroked Short strong Rods (2.0L) , Forged Crank, Piston design for cooling, Oil jets for every cylinder, 9.5 Compression ratio, SS valves, etc...etc... of course the engine is not gonna put out crazy horsepower without Forced induction its built for it.....built to take the pressure...stock bottom end and its already been proven to take 19 PSI. Take a Honda engine wich is built to be N/A with all out Horsepower (wich still makes less Torque then the LSJ without a Supercharger) and strap a M-62 supercharger on it and run it to 19 PSI and see what happens....

Take a stock 2.0L LSJ with no supercharger and a stock 2.0L honda Engine K series and run them at full RPM non stop see wich one will die first... point is LSJ is a stronger Engine with more torque regardless of the supercharger.

Take a stock 2.0L Honda engine strap a comptech supercharger on it ...run it at a safe 6-7 PSI and check the compression on the engine after 20-50 000km ....trust me its not pretty I have seen it so many times......ask my Brother in his Civic hybrid turbo....4th engine this year my dad cant wait for him to get rid of those broken pistons , shadered blocks, and bend rods....

Wanna know what Honda does better then any other manufacturer ...the Engine head...they work magic on the Vtec heads.....

To each their own.

 

I ran my Vtec Hybrid w/ 28psi for 40k miles... couple of blown head gaskets but only becuase I was too cheap to get it o-ringed

 

Where talking about engines here and not the car itself. We all know that the Cobalts weakness is to put the power to the ground. When that problem gets fixed....the torque that everybody is so high on will leave the Blown K20 2-3 cars behind. Trust me you will see... I too am an EXhondaman and there is a reason why am an EX.... To each their own

 

Ok ok just dont beat me up

 

Oh and please give me the details of all the work done on that engine?
Manufacturers of parts(pistons, rods, block guard, Fuel management, etc..)? Engine type B18? 28 PSI what turbo was used? oh and how much money did you spend $$$$?

 

denny, i'm aware if not properly tuned a f/i k20a2 engine will blow. i know a handfull of people that have either a turbo or s/c on their type S w/ hondata k-pro w/ stock internals that have had it for years now and have had no problems what so ever. true they don't race all the time but who really does? they drive them hard at the track and sometimes on the lonely country streets and never experienced any problems. not even a check engine light. i've heard about alot of k series engines blown but that was due to either a cheap ebay turbo, not tuned properly or just plain stupid and racing it all the time. 11.0.1 is not that high of a compression that it will automatically blow if you force feed it. the k20a, type r motor, on the other hand is 12.0.1 i think, and that i've never seen force fed.

 

On a side note, the new SAE standards for determining horsepower from manfacturers engines has determined that Toyota and Honda to be liars on thier horsepower ratings.

and your source is?

 

Yeah they do. 6-8 Pounds of boost is fine on those motors when they're stock. Anything over that is trouble though.

 

yea, look at any turbo kit for sale for a n/a motor with n/a compression. they give you limited gains because you can only run 6-8psi safely. anything after that you need to change the compression to around 9:1-10:1 and/or some serious tuning. you try slapping on a gt35r to a n/a motor with like 11:1 compression and run 25psi....haha

 

You answered my question thanx

 

For all those saying that GM can't build a good N/A 4 banger, anyone remember the 2.3 HO Twin Cam? 190 hp I think, and thats with no valve timing. No rediculous redline either, which means it actually had to have some torque to get that much hp too

 

there's hundreds of articles on them, from autoweek to normal newspapers.... toyota and honda are guilty of it, and i'm not sure how anyone hasn't heard about it, as big as this was at the end of the summer:


where's that "i got pwned by the honda factory icon"

 

Its either the last issue of hot rod or car craft.

since they (honda/toyota) have adopted the new SAE testing the numbers for the rsx dropped from 210hp to 201hp. never said they lied about their #'s. they used the old SAE testing for the '05 rsx-s that's the reason it gave 210hp. the motor stayed the same for the '06 model but dropped 9hp due to the new testing. once again, they never lied about their hp ratings. they just adopted a new SAE test for their vehicles.

 

Wow.... they did not lie about anything. They just tested differently then some of the domestics. That is why DC52NV asked where your source was because you sound so uneducated.

Mod list...

I can bring in some more examples, but that should take care of most disputes.

 

and where is that engine at now? if it was so great why did they get rid of it?

 

indeed, the ivtec is lightyears beyond the eco in terms of technology, although the eco has its strengths where the ivtec has its strengths too

 

sorry could you post that again, i got lost reading about the 1000 hp stock block ecotec build book instructions, that the car manufacturer tells you how to do.

could you point me to the link from acura where they tell you how to build a 1000 hp 4 banger and all the part #'s listed individually? that's the example i would like

 

do you have a link to this 1400hp stock block ecotec? is this a daily driven vehicle? that acura is daily driven.

 

i meant to post 1000

it's in the gm build book.... and who cares about what car it's in now.. point being this setup can be put in any of our cobalts, and we got manufacturer support.. it's only a matter of time. you guys are comparing a car that's been out for 4 friggin years to one that has been out for about 10 months... don't be a hater man, just accept that honda isn't on top of the 4 banger market anymore. gm with saab have taken over
