[stevesss]

There are alot on this forum that claim and write alot,99% of it is just plain B/S when it comes to a B20Vtec engine,when Toda or Tinkerbell write something take note its very good info.

ive converted from B16 to a B20VTEC and i must say the torque and power is tremendous.

as soon as you put your foot down she picks up the RPM very very quick and looses traction from 1st-3rd gear on 17inch wheels street tyres lol.

im working on my sussy setup now and might take her to the tracks ... but will need more cooling parts like - oil cooler, full length radiator and better brake setup - SS braided brake lines, bigger calipers or spoon calipers/rotors to suit.

i would say - do it if you have the budget - ive driven B18C and turboed B16's ...still nothing compared to an all motor built B20VTEC FTW!

How is it for a daily though? is the low end torque any good?

[Vvvtec]

The low end torque would be one of the best things about a B20vtec

[blabla]

Would love to have one built for my car. Sick of no down low from my b16 but everything comes with a hefty tag

Yeh its awesomeness lol.. My s300 is tuned with a nice hefty vtec curves all across the ranges... Low or high end put ur foot down the rpm/speedo climbs up without any struggles.

Wurrdd.. Helps aswell with a good tuner and im running on E85 fuel too..

Originally was going down the forced induction path.. But since i alredy have a turboed fozzy xti (225awkw) there was no point in having another turbo car.. Not worth the fuel costs nowadays.

Thas right nice hefty empty pockets with a hole through it.. After u sum up all te costs involved.

But at the end.. 146fwkw on normal tune and has plenty of potential for my v2 final tune. Hoping at least 155+kw ..

wot u got done to ur b20 to get that power?

b20 man by the time u spend money on the b18c u can build a decent b20. plus more torque and more power. and b20s have been proven to be reliable.

tru that.

wot u got done to ur b20 to get that power?
