I'm debating on going with new twins (M2) or going with the XS TO4E kit. I'm going to be running it on a stock motor with 62K miles. I plan on keeping the boost around 12psi. The following mods will also be done:
-Power FC
-Greddy FMIC
-walbro FP
- stock primaries, 1300cc secondaries
-midpipe
-catback
-DP
-Boost controller

Will running the XS TO4E on my stock motor with these mods be ok for a while till i rebuild???? thanks guys

go for the single, the twins suck.

in addition to the above mods, you will need 1300 cc secondary injectors, a fuel pump, ignition amplifier, and upgraded plugs and wires, and then dyno tuning. You should be fine after that.

 

Like said, get the single. I don't think you necessarily NEED and ignition amplifier but it wouldn't hurt. I don't have one yet, but will get one soon. But since you will be putting bigger injectors in you will need the fuel pump. I would recommend the Nippondenso Upgrade pump that rx7store sells. Very easy to install.

Thanx for the info guyz... yes, i am leaning toward the to4e kit. One question that still remains for me is it ok to run this setup on a stock motor with low boost...say around 10-14 psi until the rebuild??

The simple answer is yes. A single has alot less complication and heat generation.
