That seems pretty inefficient, but then again I'm new to shit subject! What kind of numbers am I looking at for a perfectly sealed system?

Thanks!

#1. the stock ka tranny is the same as an sr and hardbody. They are good to around 400ft lbs. If you go bigger, the z32 trans in near undestructable. Mazworx sells the adapter kit for sr20.

#2. The ka and sr will hold about the same amount of power before they pop which is around the 400-425whp range. The ka has a much stronger block though being cast iron versus the sr having an alumi um block with floating cylinders like a Honda motor.

#3. Rear mount turbo systems suck balls because of the heat energy lost through the 8ft of pipe going to the turbine housing. They are normally used on cars with super cramped engone bays like newer vettes. A 2871 disco will make plenty of power for that truck and not grenade the bottom end.

My bad. I've reglected te 620 for a bit. Got side track with buddies projects. No new things

Done to it since last update. Just sold my bike so have a good chunk of money to throw into

The truck again. Harness is going to a local shop to get cut and rewired to do a wire tuck.

Just ordered new cams and valvetrain for the sr. Can't wait to get going again. Hated seeing it sitting in my garage unfinished

. Will have pics and updated when I get parts in and installed

Wait, so just to be clear. The SR20 bolted to the stock motor mounts, and the body of the KA tranny bolted right up too?

 

I've got a '77 620 that I was thinking about putting a KA in but they're getting hard to find for a fair price so I started looking into an SR swap and found your thread.

I think that most people GREATLY underestimate the cost of a swap. All the nickle & dime crap adds up really really fast. 

 

 

Yea....After reading this thread and a lot of other threads...seems like people give up on the builds.
