How much performance do you think you could get out of it?
I'm trying to think long-term. I just got my Camry maybe a month ago, and am learning quite a bit by reading. I know going n/a won't yield me the the most power I could get with going turbo or s/c, but realistically, I don't have a flow of money that would get me a turbo or s/c within any recent time-frame.
I'm curious of what would be a good compression ratio, for an n/a 5SFE, too?
If I understand correctly, the higher the compression, the quicker the acceleration and the lower the top-end, or do I have it backward?
Any input would be nice. It looks like it might be something I could eventually afford and that would offer a pretty large difference.
Complete Gasket Set
Cometic Head Gasket
ROSS Forged Pistons
(87, 87.5, 88mm bore) and (8.5-1, 9.5-1, 10-1, 11-1 comp ratio)
Performance Rings
Performance Wrist Pins
TOGA HP Main Bearings
TOGA HP Rod Bearings
Thrust Washers
Timing Belt
Expansion Plugs
If I remember correctly from past threads, the stock 5SFE uses a 10-1 ratio. If all of the above is correct, would an 11-1 ratio give me quicker acceleration and still be ok for the engine?
I know I'm getting way ahead of myself with this thread, but I'm just getting really curious of the possibilities, and after a night of researching it, I'm antsy. :p
thats true.. i wanna see how much power you get from spending $900, i'm all for all motor but you gotta see the numbers, or atleast see if anyones bought the kit and dyno'd their car.
I wouldn't rush into anything... but that's just me
Originally posted by big_p31 damn...only if i had the money...y dont u just get a v6 swap first...then go with the kit
like I said, too much $$. Plus, I'm hoping if I can get a good compression ratio, between that and a couple mods I'd have done before hand (intake/exhaust mods) I could pickup quite a bit of power from it and keep the engine light.
its not that much....zoni got his v6 when he did his swap for a think 600$ and it had something like 80000 miles on it....im just sayin...make sure when u buy this kit that ur goin to not later swap to a v6.....cus u prolly will

Higher compression ratio = more torque.

That would be a tremendous waste of money for a street car. If your building a race engine strictly for the track that will be running 108 octane fuel and a user programmable ECU, that’s a different story.
Running an 11:1 compression ratio a street car you will be forced to a run a minimum 93 octane. Even with 93 octane fuel the factory ECM will be constantly controlling knock by backing off ignition timing, which will kill off most if not all the additional power the 11:1 compression ratio would produce. Not to mention the fact that the stock cams would be a major limiting factor in this “all engine” application.
Lowering the compression ratio in order to run high boost (if you were adding a turbo) would be the only viable reason to change the compression ratio on this particular vehicle. Other than that, changing pistons in this particular application is not the way to go.
My suggestion would be to save your money and get a low boost S/C.
