Question Questions: for Swapping from 13brew 4-port auto to a 20brew

What major changes do I need to make when swapping from a 13brew 4- port auto to a 20brew. Do I need to swap the tranny too?

It's a whole redo on the car. ECU, Harnesses, I'd assume the tranny would be changed because of the power increase

first of all the engine you have is not a 13b-rew, and when you swap to a 20b expect to spend a **** load of money

I think the "crate" motor for the 20b is like $8995 or something brand new plus shipping. Then install time and costs


The shop near me I think said that the one 20b install they did costs in the range of $30,000

Yes, but there are extra expenses to fix it and customize some of the parts to keep up with the 20b engine's power and configurations

1. you drive an auto...you need money for a tranny

2. the engine is NOT a direct swap

3. the time to do this is WELL over a couple of weeks

4. you WILL spend a **** load of money on custom parts to make it fit

5. you WILL spend a **** load of money on the ecu and tuning to make this run

People don't typically use the stock Aisin transmissions for the 20B's.

It's going to take well over a couple of months... not weeks.

I'll list the most important parts you need.

1) 20B
2) Transmission
3) Exhaust Bearings
4) Blinker Fluid
5) Motor Mounts
6) Engine Management

Those are some of the most important parts you need.

1: Everything you need
2: All the other parts you forgot you needed
3: A professional mechanic. (Customized to have Rotary knowledge)

It's not like dropping a stolen motor into a honda...

I'd aim at 30k bucks. If you're buying an ebay motor, you don't know the condition it's in. You'll want to open it up and more than likely need to do a rebuild. Then all of the fabrications you'll need to do...yeah, 30k is a good number to think of.
