Just read this thread..............hmmm.......if Samuel was here.......it would save all those rumbling and mumbling.........................
I'm always there for 4AFTE & 4AGE 20v!
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.
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
