El Cheapo Alternator Upgrade for 22RE
terryp500@yahoo.com is the man to talk to regarding this upgrade which can be viewed at http://home.earthlink.net/~twopapa/bigalt.htm#85up. Was looking to put more hp into my alternator by rewinding, converting to GM, etc (northern Canadian winters brrrr) when I came accross this mod which takes a 1994 Honda Del Sol Denso 90 amp and changes out the rectifier to Toyota. The unit is physically somewhat bigger than my original 60 amp, it fits- although I had to dremel out and press/epoxy a steel nut as the adjustment stanchion does not have threads like the old unit. Haven't fired this baby up yet as I am finishing up a head upgrade and timing chain but instead took the opportunity to change the unit while evrything was out. Another thing in make sure the new unit comes with a v-belt pulley as the original pulley will not fit the shaft is a larger diameter on the new unit. Another comment would be that there was minor shipping damage that was deemed by both Terry and I that it wasn't worth the shipping costs to rectify- he doubled the warranty instead. this is almost a direct fit.

Yeah, I was choking on some of those prices, this being a factory Denso variant it should prove very reliable. I'm sure there is way more powerful conversions out there like some of the GM varieties but this was simple.

When I was reading the linked article, it seems Toyota used about 4 different plugs throught the years- but the rebuilder new exactly which plug was in the 4runner. I did not do the conversion myself- Steve did (partsbookie on Ebay) I won the auction on a reman Honda/Denso and he did the conversion at no extra cost, I insisted that cost was no issue for oem bearings and brushes but he said his components were as good and he would use a used oem Denso rectifier vs a new one from ???Taiwan. Fit was very good with no issues with PS pump or rad hose, just waiting for a lower rad hose to finish up.
Should be able to see pics on te first post.

has anyone looked into another toyota platform for an alternator solution? I have an 89 pathfinder that came with a 60 amp and I was able to install an alternator from a maxima of the same year which was a 90 amp...both cars have the same engine, the maxima's being sideways front wheel drive. I swapped the pulleys and ground the spacer a tiny bit and it was a perfect plug in, bolt on upgrade...maybe a camery alternator would fit in a similar way?

Ya the nut is a little hokey- but you have to accept the bad to get the good or tap the whole thing and I wasn't sure the adjustment slot would accept a bolt that diameter- not to mention I don't have a tap set. Too bad Toyota had to bury the alt so deep- I'm thinking the PS pump should have gone there as it has a remote res anyway- too hard to get at to play around with- I'm all about reliability here. As far as interchangeablility goes- I did my research and am happy that there is no direct fit out there- why else could the aftermarket charge so much for HO alt if people thought they could get away with a direct fit 90amp....To be honest I'm a GM/Chevy guy and at least for the older stuff there is good interchange. Just a note- Terry may be the guy to ask about that interchange business- BUT a comment was made that he has been doing this for 20 years and was both surprised and impressed with the article.

Well my location is a little different- for example I've been waiting for over a week for a simple lower rad hose...bs. So I have to keep it simple for maintenance and availability with a limit on custom parts- the old alt will fit no problem, this is my only vehicle in this location, I should actually get another HO alt as a spare. The 90amp also was bigger- I wonder how many case sizes Denso used- if it is the same size as the Lexus- perhaps the guts will interchange with a case that requires little modification? Another question- my truck is pretty base- I thought 90a would be good enough- what situation calls for 130a? Big subs, winch, lights....I'm sorry you'll have to translate 'tree fiddy' as well....$??

90 supra and cressida are supposed to be bolt in.. 90 amps
I picked one up at autozone $124, but it comes with a flat belt.
I ended up going with a rebuilt 130 amp for $90 instead.
I started with a 1984 40 amp, so I have to use the newer brackets and wiring too.
