View Full Version : Cheaper to swap or Rebuild

I have a ka with 160k on it I know it's been drifted hard in the past and I haven't done a compression test yet but I already assume the worst.
My end goal is to reach 230-250whp on a T25 build. If the compression is bad is it easier and cheaper just to buy a used engine with good compression or rebuild the existing engine?
If I do rebuild it I was planning to do a full factory rebuild with maybe like a metal head gasket and arp head studs because I think my end goal is reasonable for factory parts.

budget 5k for a typical sr swap and call it a day. Why mess with murphy's law? Buy local after a compression test, and have everything ready to drop it in the instant you get it (it should only take 1-2 days max. It takes me about 8 hours now, in AND out) so if it starts up knocking you can complain and take it back, most places honor their engine's "startup warranty" for 30~ days.
KA engine is a great reliable beast, but god help any novice non-mechanic that trys to turbocharge one.
The same shall Forget about opening it up, even with his help.

It'd be cheaper to rebuild in the longrun for that power level. It only took me $2500 to completely rebuild the last KA I did with nismo mounts, arp studs, acl bearings, oem parts. A turbo kit might bump up the cost a bit. SRs are cheap but by the end of completing the swap youd be in the same cost as rebuilding and turboing the ka.
Im selling a whole built sr20 swap for $6k. Engine, trans, wiring, tuned haltech, twin scroll GTX3076r. Full build pictures and reciepts available. Just another option that might save you some $$$ in the longrun.
