4AFE Turbo vs 4AGE Blacktop

[Veloc]

Wow... Suddenly so many reply...

Well, about 16v, I am not a fan of that engine. although max-out tune is much more powerful than the 20V, but I am looking for good economy & drivability also. 16V lacks the VVT mechanism thus it is running on high cams and high duration cams full time. This causes FC and low end torque to be poor. I prefer 20V. although max-out tune is not at powerful as 16V, but it is good for day to day driving.

Concerning supercharge, haha... No offense. But I don't like the idea of wasting the energy at the exhaust gas and drawing energy from the engine itself to supercharge back the engine... And supercharger is not so rev friendly ^^.

What I am looking for is... In about 4 years time (mid-term aim). Good Fc. Good reliability. Not so high maintenance. Decent torque and power (no need insane power).

In long term, (around 6 years time), I am aiming for GOOD POWER.

So now, I have to chose an engine as a base. It is either:

i. Stick with 4AFE. Boost it lightly. After 5 years, up the boost for max power.

or

ii. Get a 20V halfcut. Use it stock. After 5 years, boost it lightly with minimal mods. (because I don't want to touch the internals. High boosting 20v is a lot of work.)

Actually my debate within myself is only between these 2 choice....

thread discussing BOT weh!!!! balance of high comp system with turbo and characteristic is also different.

Just read this thread..............hmmm.......if Samuel was here.......it would save all those rumbling and mumbling.........................

samuel was 4afte right? unfinished business and now happily with 20v 4age. no more turbo. but i also got a friend who owns a 20v 4agte, not finished also.
p/s: my friend's BOT kit for blacktop is with me now, summore for sale hehehhehehhe. pm me for price.

charging the 4afe up is gonna be a cheaper option, the expense needed to get a 20v cut can e used to get better internals, better turbine, etc.

I'm always there for 4AFTE & 4AGE 20v!

CEO, mine was finished but not satisfied only ...

Speaking from my experience

BOT on an 4AFE cost much more than 4AGE 20v

Of cos 4AFTE can gives you higher output as it goes by the cost ... you really need to rebuild the based & the internal parts properly before you can upgrade easily without hassle ... BOT on a NA engine is very different from upgrade a turbo-charged engine. It needs a lot of solid foundation before you can upgrade else you'll tend to abandon it after a while. ~ like me :(

you'll never satisfy with the low boost after the amount of money you spent over the power you gained. i.e. 0.5bar ... I thought of that when I opted for BOT over 4AGE but it doesn't even last me for a month with the 0.5bar BOT. The moment you ask for more, it will slapped you with more problems. i.e

slipped clutch (if you're using ori clutch set)
Map sensor (if you're using a ori 1)
fuel pump
boost controller
intercooler
turbine not big enough
lagging

Conclusion
If you want to have hassle free city driving with minimum cost, I would suggest you go for 4AGE 20v but if you don't mind spending more $$$ for better foundation with just 0.5bar with much upgrade potential, then you can go for 4AFTE. No doubt, 4AFTE will tend to fulfills your hunger ...

Its just my 2cents

Veloc,

From my understanding 16V dishes out more low end torque compared to 20V. Also when you say Good Power how much whp are you looking at?

Bolt on forced induction system always give a lot of prob, unless it's default built out from the factory. Turbocharged has more maintenance as well. It's still best to stick with N/A, unless u want a turbocharged system, then go for 3SGTE.
