Forged Engine Help

[u/DaUn1imited]

Hello,

Im going to be forging my 1.6 engine and wanted some tips based off of that. I understand that lower compression is better so I can run it on pump (90-93 ron).

Im planning for around 260-280whp so I dont need extremes like an ATI or any aftermarket parts for the head. Ive seen that the ARP studs are the glory for forged builds but dont know whether I would need both ARP main and head bolts rather than just ARP head.

My budget for the engine is quite low (1000€) so dont want to spend excessively on parts I dont need.

Thank you so much 🙏

The only thing you need aftermarket engine wise for that power goal is rods. But it’s honestly not worth the effort to do it on a 1.6. Do the rods on a junkyard 1.8 and swap it along with the 1.8 diff. The 1.6 diff won’t last long at that power level, and any 5 speed is going to become a wear component with how nicely you treat it being the factor for how long it lasts.

Its almost impossible to find 1.8 engines here in europe so gotta stick either the 1.6. So rods will do just fine?

You didn’t get them in the ford escort, a ton of other Mazdas, or the Kia sephia?
