I'm doing something similar with my DR30 but not sure what your definition of cheap is.
Mine is almost on the road but owes me $10k with
Minor chassis rust repaired and fully proofcoated underside
Seatbelts rewebbed
A/C unit converted to new gas
WRX interior
Nolathane front end
New lower control arms
Koni Shocks
Momo Sports steering wheel
Autronic ECU and boost controller
plus plus plus it all adds up
But hopefully mine will be a better example
