Ultimate Beta I NA build questions...

[Coal_forge]

178 hp (not sure which country HP) 135 ft/lbs i believe the torque was in kg/meters

18.7 =135
178

sticky? i could use some of this in the near future. kudos to everyone that contributed.

i'll second that - would like to see some numbers to back this stuff (displacement etc...)

I gotta finish my Camaros off first - but i'll be coming back to look for this post - thats 100% for sure

pistons will gain you a 11.0:1 compression

now if you do a 1.8 piston/rod combo and install it into the 2.0 youll have about 7.8:1 compression then you can boost the hell out of it and forget any plans for NA


NA 4 cylinders arent worth the headache
BUT if i was going to do a NA setup for decently cheap i would:

regrind cams to somethin like 272 duration
1.8 pistons on 2.0 rods
shave head down a few mils and get 12:1 compression
p&p the head, go larger on valves and get the quelch area cleaned up
tubular IM with a nice sized TB
header and exhaust

So what you guys are saying is that you can take the pistons from 1.8 and put them on the rods of a 2.0 and put it back into the 2.0? Also use the cam out of the 1.8 into the 2.0 also?

Right. What will the engine be used for, and what kind of trade-offs are you willing to live with? Power doesn't come without a price, and more often than not the price is drivability, noise and a nice and linear power delivery(read: a powerband only three or four thousand revs wide)

Ask yourself how much of this you can live with, because it's a bit of a pain in the arse to even get a highly strung NA motor down to the track without it being on the back of a truck LOL.

Most people have already seen my multi page thread:

I was making 160whp with 250-ish Cat Cams (very small) and a stock bottom end. With just pistons and bigger cams, it would've easily done 180whp. I still plan on building another motor, but right now I'm still working on the Z. I currently have the highest HP and quickest NA Z in Vegas. I have cams going in it today. After the cams comes nitrous, then I can start procuring parts for my Beta motor build. Haven't figured out what kind of Hyundai to stick it in though. Thinking Accent.

I would boost the hell out of it. I wouldnt go NA. Just because if you can swap internals and lower the compression then boost would be the way to go. I in the progress of doing a 1.5L turbo on my Accent. One day im going to build me another motor and its going to be a Beta swap. Im just gathering info for future use. Just keeping my options open.

Has anyone swaped the 1.8 pistions on to the 2.0 rods. any issues with this.

I also read about the 1.8 cam can be used on the 2.0 as well, or is that the crank shaft?

Original poster wants an "ultimate NA build" bro.

Understood.

Just answering the question you asked.
