What to get

[ducky]

wont work like that. you need to set a solid plan for the motor first. a boosted motor NA is a dog, a NA motor then goes to boost is limited to boost unless you run race fuel

haha im sorry George im so confused as to what your referring to NA as. read the sentence and make sure im just not dumb lol

NA nobody wastes any time building a NA motor under 11.1. a healthy NA motor is 11.1 or right around that. now ifyou try to toss boost to it youll either have to run little boost or high octane

oh right right I get it

George...why can't I build a motor for boost but run a solid N/A cam until I get the money for boost? There is no such thing as an overall solid motor that can run either way with a swap of a couple parts??? Like a different set of heads and a cam for instance?

I would totally go with forged internals I just don't know where to get them...also who to go with.

Would be nice if you mentioned HP goals. Personally Id do an LQ4 with L92 heads.. then again my HP goal is completely attainable N/A

I want around 450 to the wheels. I'm pretty sure that I could attain that on a N/A motor as well.

But hey if I can't do both on one motor then screw it I'll to with a nice amount of spray.

most boosted motors are 8.5 to 9.0 which makes for a dog NA. now you could build it 9.5-10 but wont run as much boost safely on 93 octane.

any decent cam likes compression, so lack of compression is goign to make the NA cam doggy. flow of heads, intake and internals arent that big of deal, just how the compression and cam choice thats all.

What about domes vs. dishes pistons? Swapping between them would bump up or lower compression correct??

What about boost on 10:1 with high octane? Maybe 8-10lbs??

[George C]

you can change pistons yes but that is rebuilding a motor honestly. so you spent money twice

10psi on a built motor? id much rather run more tell you the truth. hell i run 18 on stock motor

So how much higher or lower could I get compression wise...mainly just being curious.

So would 10:1 be enough to have a decent motor with a decent cam and still make DECENT power. How much boost you think I could run...semi-safely...with 10:1?

10 is an average motor to run in both directions. theres ppl running good bit of boost with 10.1 cr just would have to run good gas.

10.1 is little low for big cams but ls1s do it and work well. Just for me if i was building a NA it would be 11.1 to 11.8 cr

for me a boost motor 8.5-9.2

[bangbangskeetskeet]

I know ideally I want around 11.5:1 compression...but with 10:1 would I still be able to make a decent amount of power with the right cam/head combo?
Then swap cams and boost it and still run like 10-15lbs of boost? When its boosted Im not looking for any land speed records or HUGE hp numbers...somewhere in the 600-700 range...I just wanna be able to toy around with it and run down some sports cars....

Is this doable at all?

Oh and I never got an answer...how much higher or lower compression could you possibly get by JUST swapping between domed or dished pistons?
