Topic: 6 cylinder to 4 banger?

[94yota]

My 94 v6 has no compression and has 200,000 miles on it. what will it take to drop a new 4 cylinder in my truck.

[bigarms23]

it an easy swap but you have to put in a 2.7 4cyl because in california you have to put the same year motor or newer according to the dmv besides with the 2.7 you can get all the swap stuff from offroad solutions.com

a buddy of mine has that engine in his tacoma and digs it. he doesnt wheel much really, just trips up to mammoth and bigbear, and is really only in 4 maybe 30% of time up there. he says he gets good gas mileage and it hanldes the grades well. another alternative would be the 3.4L-5vzfe. i will prolly go that route with a kit from the heart swap masters at ORS. i do feel that either way you'll have better mileage and more noticable power.
do you have an 5spd manual shifting transmission  or an automaically shifting transmission?

[weirdtimes_7]

X2 on the 5vzfe... thats what i'm doing to mine when i blow my 213K mile engine.. i think i got at least another 100K before i got to swap her..

Yeah, if you have a manual transmission, there's no real reason to have a 6 that's only a little more powerful but a lot more complex and expensive.  (plus fuel economy of course)   150-170HP was common, and the later 4s put out just 10-20HP less. 

Oh - it's actually VERY hard to find a 4 speed in the mid 90s with manual and 4x4.  Almost all of them were 6s. 

edit: that means it's okay to be different

[Redeyejedi]

yea the 3.4 puts out from 170-190hp but 180 -220 ft-lbs, while the 2.7 only puts out IIR 160-170 ft-lbs.  i saw a chart on one of the boards listing the 22r, 3vz, 3rz and 5vz and thier output figures but now i cannot find it. i thought i bookmarked it..... will keep looking and post link when i find.

but here big mike has an excellent writeup

I don't know if this would fit at all, but the specs are sweet.  This is from a later Tacoma and it's essentially a turbo R22E power-wise without needing the turbo.  You could get better engines, but this is probably going to be the simplest to get parts for and swap in of the newer engines.(plus totaled Tacomas are pretty easy to locate if you want to go that route.

This should give you a comparison versus an older V6.  This is what I meant.   Basically you're wasting two cylinders worth of fuel for no gain(okay - a few more lb-ft of torque - not even 10 at 4000rpm(so it's a fair comparison) with the early V6 versus the later I4.

Oh - enormous list of engines:

Umm, the 3vz-e is the older v6 model, the 3.0   the later model (3.4) is much stonger, and has a lot better torque.  It is actually an engine that feels like a v6

[Plekto]

I know, but my point was that the V6s from when his truck was new are hardly any better than the 4s they make now.   He could get a newer V6, but the sweet thing, IMO, is to toss in a newer 4 and get the same performance, or very close to it(considering the 100+lbs less weight of the 4 and slightly quicker to rev, most likely the same or better)

That engine in a Tacoma is rated at 26 highway and 22 city.  Pretty decent, IMO. (I wish I got anywhere NEAR that with my R22E)

Very nice as you said.  But not a HUGE amount better than the 4.  Not like the 250HP+ they are getting out of, say, the Avalon's V6.

[Redeyejedi]

i think the noticalbe difference is rather huge. the numbers may not be all that...but the 5vz is everything we 3.0l owners wanted to begin with. more power and upgradable to well over 300 fhp, tows better, climbs better and it's also less thirsty(than the 3vz). i am always movin ish around and appreciate all the reliable power i could get outa yots. the 2.7 is an awsome plant too. it all comes down to goals for the rig i suppose. for me....it's a supercgharged, well breathing, 3.4L '98 or '99.
