N/A V70 to factory LPT Modification

Post by JIMBOslice »

Hello,
I'm looking to get some more power out of my 1998 N/A V70. I came across someone who had put a stock LPT motor in what used to be a N/A 850 and it ran fine with the stock N/A ECU. This inspired me to consider doing the same or similar thing to my car, but really did not want to swap motors, as I have done a lot of maintenance to mine, and it runs well. Since I am in need of a new exhaust system anyways, and the LPT motor is quite similar to the N/A, I was just going to get a used turbo, injectors, manifold, inter-cooler, and piping, and add new coolant lines, oil lines, and an oil cooler to add on to my car. Is this something that can be done without blowing up my current motor? I know it only adds a claimed 8 psi, and that is all I am looking for. Any advice would help greatly and would be much appreciated, thank you.

Nope. You'll bend rods. Turbo models have reinforced internals.

Have you tried the 960 throttle plate modification? Do a quick search on the site here.

A learning experience is one of those things that says, "You know that thing you just did? Don't do that."

I have not tried the throttle plate mod, but absolutely will. I am trying to find information on the rods and structural differences between those of stock Light Pressure Turbo motors and stock N/A motors, but have had no such luck. I understand that if I were to do this modification, I would absolutely run low pressure and probably back off the boost until higher rpms, preventing low end high torque conditions that bend rods. I may just save this project for when the motor needs a rebuild and then install upgraded rods/pistons/ crank/ heads, way in the future.

Compression is going to be different, injectors, timing, tuning, internals, exhaust size, maybe some more but off the top of my head those are the most important things! Just buy a LPT car and be done! The work and headaches will not be worth the time! Always easier to build boost on an already boosted car!
