have 4 question:

1 - I do a driving bottom have a b16a2 and I want to put b20 but it is better a B20Z or a B20B? I know that the B20Z is VTEC thus the modification should be easier?

2 - with a head of B16A2, B20 it take 9000rpm without problem of breakage?

3- with would B20/vtec you use one gear box B16 or B20?


4- And which ECU is worth it to better use B16 or B20?


excuse me I know that there was several topic on this subject put the sentence are written so that the translator cannot decode them correctly and I do not manage to include/understand the sentences, therefore if you would have the kindness to make less possible fault I would be very grateful to you

excuse me for my English but I use a translator...

 

none of the B20's were VTEC

You can use any vtec head on a b20 block with modifications

you can use any B series gear box, B16, B18, etc.

you will need a vtec ecu to make the car run properly

don't take a b20 to 9000rpm unless its built to make power there, and is strong enough to take it there, a stock b20 bottom is not strong enough

No b20 tranny - fab...(4wd bro....)

 

1. yes, they are right in that no B20 was ever made w/ vtec, but go for the b20z for its higher compression (9.6 vs. 8.8).

2. I would not take the motor pass 8k regularly if you want to keep it for a while, plus you probably will see peak power at 7-7.5k rpm w/ this motor anyways.

3. use the b16 gear box.

4. use the b16 ecu, but give it more fuel w/ a regulator, injectors...etc.

hope that helps
