Ok so I took inventory in my garage and I have a bunch of parts lying around that I want to play with.

 

I have been enjoying the power from the EJ18 BRAT but as we all know, there is always a need for more power!!!!!

 

Here's what I have.

 

2 EJ18 long blocks

1 set of EJ22T heads

1 EJ22 phase 2 short block

2 EJ18 intake manifolds

 

The plan it so take the BRAT and drop it down to a 2 inch lift. Then take the EA81 4 speed and put in a s/r ft4 3.7 tranny w/lsd.

 

I figured I might as well replace the engine while I am at it.

 

So have enough parts to do one of two things.

EJ22 short block EJ18 heads for a high compression N/A motor.

EJ18 short block EJ22T heads for low compression turbo motor.

 

Option 1 is probably the easiest b/c I will not need to get turbo related parts.

Option 2 have the highest HP potential in the long run

 

So what's the verdict?

 

end goal is to get a decent handling possible rallyX desert runner BRAT.

I really like the idea of an EJ18 turbo myself....

 

i wouldn't want to mess up the great mileage you are likely getting, though.

ej22 with ej18 heads won't bump up the compression. they are nearly identical.

 

ej25 with ej22 heads is where you get the higher CR.

 

with that in mind, go turbo.

Turbo's are fun to play with. Personally I prefer the driving characteristics of N/A engines. But I reckon the turbo is the way to go in your case.

1.8 heads will not increase hp by much for a 2.2 but i have an ej18 in the BRAT so using the 22 shortblock would increase power. technically there's enough parts to build both.

correct. using an ej22 block with ej18 heads will increase power because it is a larger motor. it will not be a high CR motor. it will pretty much be a stock ej22.
