3 psi

 

Would this car be a viable n/a application? I know alot of ppl try it with the 2azfe but they dont get much out of it (in comparison to turbo application).

 

rumormill says yes but the car isnt out and modded yet so who knows at this point.

 

i think most manufactures max out most thier hp, nowadays. removing cats, and tune might be the biggest gains. will find out. i dont see toyota boosting this thing, i think it's like the s2000 in it own way.

 

so it is opposite of the 2az-fe, boost friendly.

 

With hondas s2k's we tune for 14.5psi on a stock 11.7 to 1 compression motor (480whp). I think 10 psi would be doable on the FRS.

 

I did not know this.

 

I don't know a ton about civics and that stuff but I thought the majority of turbo civic were non si and The si civics weren't turboed as often because of the higher compression ratio. Isn't a high compression ratio undesirable for forced induction?

 

Generally yes, but the s2k motor is so efficient that it makes more hp per pound of boost then any othe motor we have encountered. So it doesn't take much to make a lot of power. 480whp on less than 15psi of boost is practically unheard of for a 4 cylinder, usually takes 30 psi plus for an evo on the same turbo to make those numbers ( for example), and the motor is the same displacement. Hopefully the FRS engine is efficient.

 

^^^but tuning around the direct injection is gonna be tricky no?

 

The ecu is tunable from the factory. There are people who have said the Di is beneficial.

I heard leaving the direct injection alone and playing with the port injection will be easy and beneficial in many ways.

 

i love the sound of subbies, but hate the problems that always come up, as far as blown motors. is this motor out, and in any other cars?

 

Yeah, this one did it at 13.7 psi http://honda-tech.com/showthread.php...ight=s2k+stock

 

cant compare honda, with subbies reputation for detonation.

 

This is a completely new engine, developed by Subaru for this chassis. A similar version is available in the new Impreza and Forester, but don't pass too much judgement on it yet based on the EJ series issues.

And there are lots of very powerful, very reliable EJ's out there, but yes, some people have had issues.

 

just wondering, since ken gushi said it didn't have much power.

 

Im wondering if since it uses an existing motor from Subaru if you could use one of there existing kits for that engine with slight modifications??

 

Full-race is doing a turbo kit for it.

 

it isn't using an existing motor, it is a new motor developed for this car.
