First off I have searched, so please don't crucify me if this is a simple question.
Can people give their opinions on which is the best subframe to buy for a 20b install in an FC?
I have seen a few companies like a-spectuning etc selling a subframe for 20b install, also rotary specialities in Canada, I would just like opinions on which is best and why. Thanks in advance.

Subframe kit for a 20B install for an FC3S Chassis?? Why? Buy a set of Cosmo Re/20B FC motor brackets and bolt the motor in.. Done deal... There are tons of vendors selling them...Set of brackets will cost you less than $150.00

 

Cool thanks for that.

Take into consideration that the motor does not fit under the hood very well with these brackets. It sits too high and too far forward with brackets.
Custom fabricate the way the motor sits with the sub frame will get the engine really low and further back about 2-3 inches.

 

2-3 inches back and sitting lower was ideally what I wanted, hence the original question of which is the best subframe.

There is no best subframe. You need to fabricate it yourself. The steering rack needs to be dropped ~2 inches, shave off the front of the oil pan, relocate the oil pickup tube to the back, fabricate new motor mounts into the frame.

 

try autotechmotorsport in Chula Vista Ca. i think, there's said to lower by 4inches
and back 6-7inches and no bumpsteer issues.

 

Either pm me or GTORX7. We can make you a sub-frame, no need to worry about doing a bump-steer correction either. We will get it low and back for you, we will just modify the oil pan.

I have one from Rx7 Specialties in Canada, and even the bumpsteer kit... it works great on the FD.

I still Have it, but for sale
