1998 Toyota Tacoma w/288000 miles on the engine

I have a 98 toyota tacoma, inline 4, standard engine. I either need to rebuilt the engine or replace it. I can get a 95 toyota tacoma v6 standard engine, would i be able to swap that in? The rest of the truck is great its just the engines a bit tired of driving to and from the lower 48 to Alaska... the 3rd cylinder got rebuilt at around 200000 miles and now its in such bad shape again. Also I believe i have blow my piston rings.... the truck is undrivable as it is right now. the V6 would be coming from a rolled taco that only has 50k on it but body wise was totalled when it rolled. Thanks for any info regarding the matter! Cheers!

 

You'd need to swap the wiring harness and computer, as well as re-locate and re-weld two of the engine mounts as they are in different spots. I think @jacobrippey did a v6 swap.

 

Yup. Just did a swap from a 95.5 4 cyl to a 96 3.4 V6. You'd need to swap just about everything from the donor truck. Engine, trans, transfer Case, ecu, engine harness, interior harness, body harness, etc. Also, note that the 95-96 V6 engines can't be supercharged easily.

 

Why is it that you can't supercharge the earlier 5VZ's easily?

Couldn't you use the transmission already on the truck - wouldn't they mate up the same?

 

Early 5VZ ecus don't like boost, and completely mess up when they're under boost. Some people suggest throwing a 97 ecu on, but they're pinned differently (every year was pinned different).

The 4cyl transmission is a w59 and the 6 is a r150f. Not the same.

 

Isn't that for manual transmissions? My 3RZ currently has the A340E tranny, which is the automatic.

 

I'm not worried about super charged, as i've been driving my 4 banger for years slow and steady! However i did learn the engine i can buy from the states is a 92, not a 95... hearing that the engine swap from a 95 requires a great deal more than just the engine is it even more complicated to do the 92 engine swap? If its possible?, its a good engine from someone i trust and like i said, mines a solid truck and has held up to the miles, so its a hard truck to just scrap... thanks for the replies!!

 

If it's from the 92, it will probably be a 3.0 or 3vzfe. DO NOT DO IT. That engine makes the same power as your 4 cyl but gets v8 fuel economy. Also likes to blow head gaskets. Also, because of it coming out of a pickup, the exhaust is routed to the wrong side, the fuel line connections are all wrong. Can't tell you enough times not to do it.

 

Honestly, if you can find a v6 and a complete parts truck (a Tacoma 95.5-04), the swap isn't too bad. Just time consuming.
