Hey guys,

I got a 1988 V6 Fiero engine that I took out of a car. Got the PCM and most of parts. I currently got it for sale on craigslist but I was wondering if it would make a good conversion engine in my 72 914. The engine ran great when it was installed and had good power. Think it is 2.8L. Anyone ever did this engine swap? If so, what is involved?

Thanks,
Jason

Fuel fires,
speaking of which,the 914 is a real firebomb unless updated to modern standards.
The problem is usually a lack of maintenance and neglect,and ensuing leaks and fires.
The fuel hoses are old plastic lines from 1968 that are decrepit,so,sniff around to get a whiff of bad gas.
Old tanks are filled with rust and may leak,the injection system will not tolerate dirty fuel.
Before you start,coat the tank,re+re injector system,replace the lines with SS pieces.
Old flat fours with rusted cylinders will crap out and cost time and money.
An internal inspection before a start attempt is the cheaper way to make Porsche ponys.
Plugs out and a look inside the cylinders,use the borescope you bought for the purpose.
Drop the valve covers,inspect the valvestem clearance by releasing an exhaust valve spring,if it wiggles,nfg,pull the heads.
If they're ok,then set the rocker clearances cold,inspect the distributor,set the timing,check for the correct vacuum circuit.
Drain the old oil,replace the filter,crank the engine for a full leakdown.
Be real gentle with the exhaust headers,the headstuds will break if you tweak them.
Use rustbuster,(acetone 50/50 transfluid),on the rusted studs and nuts as a preliminary application.
The electrical harness is a vulnerable system to moisture and corrosion and must be checked before voltage is applied.
An installed safety disconnect for the battery is a good move.
Have a fire extinguisher nearby when you install the battery,you did check the groundstrap.
With a new fuel system,a good electric circuit and an ok set of cylinders and valves,
the TFour will fire right up and idle when the heads heat up.
Any question you might have will have an answer here,even the wild ideas.
