information needed for a project car

hi guy's,

recently i bought myself a Alfa 146 model. i was going to do some engine transplant project. would like to get advise from all the expert here.

1. may i know other than Q4 engine (which is Fiat Coupe 16v Turbo engine rite?), what others engine can i fit in?

2. can i fit in Fiat Coupe 20v Turbo engine?

3. how can i tune the Q4 engine up to 300bhp realistically?

1. The Q4 engine is basically a Lancia Delta Integrale engine (the same source as the running gear) - similar to the Fiat Coupe 16v engine.

2. The Fiat 20v engine, having 5 cylinders, is really too wide for a 146. It is also quite complex electronically/electrically. You can fit an Alfa V6 if you really want to (it's been done to a 145) but it depends how much work you want to do/pay for. If your car isn't a 2 litre then fit a 2 litre twin-spark engine which is an easy upgrade. This engine can be turbocharged to give an easy 220bhp, or tuned more conventionally to give up to 200bhp.

3. If you want to get 300bhp out of a Q4 engine talk to some of the Integrale tuning specialists but think along the lines of re-mapping the ECU, upgrading the wastegate (i.e. increasing the turbo pressure), fitting an intercooler, etc. Plan the whole upgrade in advance, though - don't just throw parts at it because they may not be well matched.

Could you let us know about the costing on this one, considering the 147 gta route or the suped up 146ti route, my current baby wink she's running aprox 180-185 bhp at the moment.

be interesting to hear what you do

ey, thanks for asking those questions.
IŽm thinking about changing my 146 engine aswell.
IŽve recently gone to a used parts store (here in Portugal / Esposende) and I found 4 possible donors to my car.
- Fiat 20v Turbo (From a coupe)
- Fiat 20v (From a coupe)
- Alfa 1,8 TS (From a 156)
- Alfa 2,4 JTD (from a 156)

Well, all engines were still in their respective cars and I also find that the 5 cilinder is a little bit wide for the 146 engine compartment.
The idea of sticking a JTD under my hood is not very smart due to the number of changing operations that IŽll have to do.
Than I can use that 1,8 TS that brings more 41 HP to the 146...
IŽll check out the prices friday afternoon.

My engine (1400cc) has 85.000km and runs great but I would like to have more know...

Damn "Engine swap" 146
