2.7L / 2.4L Supercharger Basics.
First, I highly recommend Gadget’s outstanding supercharger website at: http://www.gadgetonline.com/super.htm
Please take the time to go over all the information there! It’s well worth it!
- What about the 2.4L Tacoma?
The 2.7L kits should work with the 2.4L Tacoma however some tuning may be needed.
- What superchargers are available for the 2.7L Tacoma?
It gets a little confusing...
Eaton makes the blowers, but doesn’t make the kits needed to mount them to specific cars. Then companies buy the Eaton blowers then fabricate the parts needed to install them on specific vehicles. These companies either market the kits themselves or sell them to other companies to do the marketing...
The first supercharges for the Tacoma were for the V6 Tacomas and sold by TRD. They used the Eaton M62 blower.
- Who made the first 2.7L Tacoma Supercharger?
Alpine is a company in South Africa that made kits for the 2.7L Hi-Lux P/U which look exactly like our Tacoma. There are differences however, here in the EPA-USA we have EGR valves and other emission equipment not needed in Africa.
Anyway, I was the first person in North America that imported the 2.7L Hi-Lux kit and managed to modify it to work on my Taco... Nuke was the second person to buy the kit, but his kit was modified to have the EGR valve mount.
- Who made the TRD 2.7L Kits?
TRD contacted Alpine and contracted with them to make the TRD 2.7L kits.
- What are the differences in the Alpine Kit?
The difference was the Alpine Hi-Lux kit used the M90 supercharger where the TRD kits were all M62 blowers that are much smaller. The Alpine kits also had fuel enhancements like a 5th injector and the Unichip Piggyback controller... The Alpine kit came in two varieties offering lower and higher boost. The higher boost kit included a decompression kit to lower the Taco’s compression to support higher boost. That’s the one I bought. Both seem to work well with the 2.7L Tacos.
From what I have heard, the TRD 2.7L blowers had lots of problems and TRD then stopped selling the kits and URD took over selling TRD kits. I don’t know much about the TRD kits or the URD kits so I can’t help ya much there. Hopefully someone will fill in this information!
What I can say is there is a big difference between the Alpine kits and the TRD/URD kits. The people that bought the Alpine kits seem to be happy with them.
- How can I find out if the Alpine kit is still available?
You may want to contact Alpine directly and order their M90 2.7L kit if it’s still available... alpturbo@iafrica.com BE SURE TO TELL THEM YOU ARE A MEMBER OF TTORA!! Only TTORA members can get Alpine supercharges directly.
- How much power does the Alpine kits have?
According to Nuke, the lower boost kit will give you the performance of a stock V6 and it’s a lot easier to install because you don’t have to do the decompress.
The high boost kit will give you almost the performance of a V6 with the stock TRD supercharger kit. However, the installation is much more complex because of the decompression kit. This means you have to also take the head off make a few extra modifications then replace the head using two head gaskets and the Alpine decompression spacer. This greatly increases the complexity of the install and you need someone that can pull the cams and the head off, and then reinstall them. No small task... It takes experience working with overhead cams, cam timing and especially attention to detail. You need experience with this before you tackle it on your own.
If I were to do it again, I’d still get the Alpine hi boost kit because of the difference in power levels... It’s really fun smoking stock V6 Tacomas with a 4...
