I Recently purchased a 74 914 (VIN 4742901009) with what I believe originally had a 2.0 liter installed in it (original engine ID 006765). According to the seller the stock engine had one of the cases busted when it had thrown a rod through it. He went on to say he purchased a case (W0111578 ID found in front of oil filler) and took the remaining parts from the original engine to a shop here in MPLS. there they replaced the main, rod and cam bearings. Blasted-polished the crank and rods. installed a 30mm high flow oil pump. Honed the cylinders & installed and gapped new 94mm ring set. Replaced worn camshaft with a new "IV" mechanical cam. At this point the car is not drivable for structural reasons but the engine starts idles, throttles up down and sounds pretty good. The car came with what looks like the 1.7 type air filter set up and the throttle body which sets horizontal rather than the typical vertically positioned throttle body with the larger square type air filter set up.
With all that important info out of the way, I have many questions. Is this a 1.7 injection installed on a 2.0 engine? if it is, is it a huge deal? Will the 1.7 injection automatically adjust to the larger engines demands for fuel. Most importantly what specs do I use to tune the engine? Thanks Gunn |

Your engine is not really that messed except that firewall pad. You can just delete/remove that pad so you be able to see if there is some rush on the lower firewall area that needs repair. |
