The 2.5 GTi engine was an excellent conversion at the time and was more about torque than outright power. At the end of the day it is torque that gives you great in gear acceleration which is what you are after not a load of bhp and no torque. The 2.5 GTi engine used the standard KV cam and fitting a Shrick will give more power and torque but higher up the rev range. If you can live with that then it should be capable of getting to 190bhp. After that you need to look at fitting a bespoke injection system and getting it accurately mapped on a rolling road etc. It should with a decent exhaust and work to match the inlet easily reach over 200bhp with around 190lb/ft.
The turbo conversion was a nightmare and needed some ingenious solutions and is still in development as intercooler too small. It is the torque of this engine that really impresses. Presently producing around 250bhp and 280lb/ft. In gear acceleration which is the important on road figure is spectacular. 50-70 in 5th in 4.8seconds and in 4th it comes down to 3.6secs. I'd go for good torque every time in a road car.....
