Happy Monday and G’day.
From the outset, let me just re-iterate that I truly hate these kind of threads. I feel dirty doing it, and I’m exceedingly sorry for doing so.
I have a 1979 Ke55, it has a 4K 3sp and it sucks. I have been racking my godamn brain for the past few months over what I should do. From a bit of research there are a few options that I have in my mind.
1. 4A-GZE / T50.
2. Build the 4K up.
3. SR20DET
4. Celica motor ( not sure what it’s called, this is my first ever Toyota. )
5. I read someone saying second hand it was possible to put a VN / VP V6 in it? That would be rad with some sort of information.
Also with engine conversions I am aware they have to comply with power / weight ratios, upgraded breaks, engine capacity, engine year, etc. So if anyone has any tips in this regards let me know. I don’t want to rock up to get it plated / regod and them tell me that the engine would make it disqualified from being able to be used on the road.
Obviously the best bet would be for the 4A. My first instinct was the 4A. I’ve done a bit of digging around for a decent priced engine package, which more or less would include the T50, loom, ECU, etc. I can’t find anything, and the “cheap” ones I do find, I would have to fork out paying $500+ for shipping (I live in Cairns). I have looked on ebay.co.jp and would be looking at around $2000AUD landed for an engine/box minus electrics.
Second option, building the 4K. I read in the FAQ about doing up the 4K, but it really doesn’t make any indication if the gains are worth the money. I just can’t see getting anymore that 100KW out of the 4K at best (this is just an estimation, I'm not sure what a worked 4K could produce) , and for the money spent getting it to that stage would seem like overkill. Anyone have experience with this?
SR20DET. Not as common an option as the 4AG(Z)E and I would suspect it to be a harder convert than the 4A? Yet again, anyone with experience, would love to hear from you.
I have about $4000 saved up, I can do most of the inane stuff myself, but I have NFI when it comes to EFI’s.
TL;DR? What is the most viable engine swap for the KE55, both financially and performance wise.

Thanks.
