Hey just seeing if anyone has turboed a 420a engine and if you did how did it run etc. Any input would be appreciated

i have. it was probably 10 years ago. back when the only option was to use a FMU for fueling. i thought it ran good at the time but looking back, it ran like shit.
now there is hardware/software to properly tune the fuel and ignition on just about everything. so its not that hard to get them running good.

still your better off buying a GST/X
for just the cost of a MSquirt and pistons/rods/valve springs for boost, you can buy a good used GST for these days.

Would I be hard to swap a 4g63 in it because this car as a lot of sentimental value to me so I don't really wanna get rid of it... Also what do you think would be to many miles to turbo it?
