Just out of curiously... Can N/A motor beat turbo?

Can you tell me pros and cons of N/A and Turbo. I'm curious to know yall opinions.

anything can beat anything, all it takes is money

you can make your car faster cheaper with boost

i personally would rather take an 11 second all motor k series than a 600hp turbo car

Lets put it this way give 2 people both a bone stock 95 GSR with lets say 30k just to say they are equal and are healthy and $6000 to modify their cars. One has to go NA and the other has to go turbo. For $6000 you can get a turbo and tuned, slicks, upgrade the clutch and still have a little money for other goodies for the car not needed to make hp. Na you will spend $2000-3000 on the bottom end and at least $3000-4000 on the head and valve train upgrades. On the low side you only have $1000 left over and still need a better clutch, tuning and slicks and on the high side you are over budget buy $1000. All that you you are still maybe hitting 250-280whp. They turbo guy just put down 380whp on the stock motor and had money left over.
There is also a limit to how much power any given NA motor can make no matter what you do to it. Eventually you will need to force more air into the motor be it from turbo, supercharger or nitrous.

All anyone mentioned was money so far and failed to answer the question to its fullest.

Both setups will have a completely different power band, sure a turbo car makes more power, but doesn't hit peak power for as long throughout the powerband. A all motor car may make less power but the power is always there you don't have to wait for boost to build up

Sure it costs more money to make power all motor. But a 300hp allmotors car will blow the doors off a 300hp turbo car essentially..

Don't know much about engines do you? Turbo bottom ends and blocks, valves, etc. cost more than NA parts. Plus decent turbo parts, not E-bay kits, cost more.
Now if you are talking a 300bhp NA vs a 300bhp turbo, na probably cost more. will live longer, and blow a cheap turbo away.

An upgraded bottomend is not needed for a 300whp turbo setup. The average bolt-on T4/T3 complete setup can be purchased for $2200~$3000 (turbo, mani, dp, wg, 400hp IC) depending on the maker of the kit. That will leave at least half of the money for a clutch, suspension, fuel setup, exhaust and ECU. An NA setup will need over-boring, stroking, head work + larger cams, exhaust manifold, weight savings, and more but will not hit 300whp with $6k. A high strung NA setup will require more preventive maintenance and will not last as long as simple bolt-on turbo setup IF both setups are driven in the same manner.

Well for 300 bhp if a stock bottom would work foe a turbo, then it would work foe a NA, except pistons, to change compression. Same as a turbo build. More head work, and a better intake, but that is still cheaper than turbo head work and a turbo kit. Now 600 bhp is way different.

Dee

For typical 1.6~2.0 liter B series engines

NA will not be able to hit 300whp with $6k.
Turbo setup will not need head work, cams, pistons, or rods! Just install the turbo KIT, add larger injectors + pump + ECU, larger exhaust and top it off with a clutch that can handle 350whp+.


NA will need to be stroked with the correct pistons and rods, balanced with the clutch installed, larger cams with the corresponding springs & retainers, good head work, a spot-on tune, flywheel for optimal NA performance with a matching clutch. The balanced bottomend will eat up a large chunk of the money.

Good turbo setups are cheaper than you think.

..really.. is this a real discussion?

I think the op intended it to be derek, but everyone has trailed off talking about money money money

kyden

you really have no idea what you are talking about.

No not really. Forged internals are forged internals there is no special internals for boost compared to NA except the pistons compression. You can make 300WHP on a stock motor with just a turbo kit, no valves, heads work or upgraded internals needed. You can get a Go Auto kit for right around $2000 then all you need is another $1000-$1500 for fuel upgrades, tuning and a clutch. A 300WHP all motor will only make that power in the higher RMPs. Boost with 300WHP will make peak boost by 4000-4500 RPMs at the very lasted. So a boosted 300WHP car will make the same power only sooner in the RPM band and the power will come on hard and strong unlike NA where the power gradually builds up as RPMs increase and you get into VTEC. Not to mention all the TQ the boosted motor will have compared to the NA motor.
By your post it seems like you dont know too much about building engines. I have been around the block a few times.

nealnanoHX

No it wont. With a turbo you are getting more air into the cylinders by forcing it in. NA still relies on the motor sucking in the air at atmospheric pressure. You will need to sleeve, bore and stock the block or get a Darton tall deck 85mm block which is $$$$, to get even close to 300whp NA on a B series. 12:1 CR other than that stock bottom end, good head work, large cams, flat faced valves, good intake mani and header will only get you to 200-250WHP if the tune is really good on a stock motor. No head work is needed for turbo cars. 600+WHP has been made on stock heads and stock cams.
