What happens? I've never seen this question asked ever.. does your N/A motor just get super strong? Will you see any gains? Like if i replaced my pistons to lower compression ratio, rods, sleave it etc etc..

 

you will basically have a bullet proof motor.....

ready for future f/i installation...

 

If you lower your compression, you will loose some power.

 

Children with laugh at you and society as a whole will shun you.

Other than that, you will loose power if you drop the compression.

 

hahahahah

yah..this would be pointless...this is like putting a big rice wing on your stock honda civic CX....only this is 1000X worse!

 

You can spend a little more if your broke after all that and shoot a crap ton "o" Nitrous....

 

I see,

Thanks anyway!

 

Moving from 10:1 to 9:1, for insance, will result in a 2.8% power drop...all things being equal. Not a very significant decrease in power....so if you wanna build up your motor first, then install an F/I kit in the future, I say GO FOR IT!

I know in a perfect world, everyone would have the resources to do all the build-up and turbo mods simultaneous.....if the budget doesnt permit, you would successfully build up in stages, and not see too much of a power drop...while you save up for the F/I kit.

Hth,

i understand your logic sharif...but why would these car manufacturers make these motors with such high CR's to squeeze out 2% more power, yet up the fragility of the motor (i know they are NA motors and not built for FI..but still?!)

Todd, simply because of what you said, they are N/A, not meant to go to F/I. They don't even try to get all of the power out of every engine in N/A form (and of course still keep reliability), one reason is insurance.

 

The OEM's factor in so many things. Higher compression means better fuel economy, and higher volumetric efficiency. So they design an NA at the highest compression possible, while avoiding detonation. And as ECU's, and engine management systems have improved over time, you are seeing OEM's run higher and higher compression. I think the new Audi A8 runs something like an 11.5 CR....impressive.

 

I would just wait and do it all at once. You don't want to get in a situation if you had to sell your Z with the lower CR, it will lower the value.

 

or raise the value..... if someone is interested in going FI, this would be a great car to buy....... already having the internal work done makes life a lot easier........ they wouldn't have to remove the engine or anything.....

i say if you are going to eventually FI it, but can't do it all at once, do the internals first. if you go FI first, there is always that greater chance of blowing the engine, and being stuck without a car...

 

Lose has one O.

 

Yes the car will be valuable for an enthusiast shopper who knows his stuff and has FI in his pans but thatÃÔ not the majority of people out there. I personal won't buy one because I like to know who's doing the work and be involved from the beginning.
