T3/T4 brawler kit

I am trying to decided which kit would be the best TD06 or the T3/T4 brawler kit. What kit would work the best on the MR2 without alot of suporting mods? What kind of suporting mods will be needed to suport the turbo kits? Right now I have a Apexi N1 (SP) exhaust, Nology power core 0.6 to 1.0 Ohm, GReddy profect B boost controller, GReddy boost cut controller,GReddy innercooler, NGK copper tip spark plugs, magnecor spark plug cables, and a K&N filter. What else will I need? A list of mods and horse power numbers would be great!! Thank you for your help!

Both kits are really good and relatively similar.
If you go with the TD06 I would get an external wastgate for it (talk to ATS RAcing ... click my siggy pic).

In general, the TD06 has made more top end power and the T3T4 kits tend to spool faster.

Would I need to use a piggy back system or a EMS? What mods will I need for these turbos? Thank you for the information Jekyl, it has been very helpful :)

You could bolt either of these kits on and run 14 psi without additional mods.

If you want more boost (and power) from them, you are going to need resolve fuel issues and computer issues.

ATS racing sells a fuel rail bore service.. And if i remember correctly its pretty cheap.

Get that, a warlbro fuel pump, and supra 550's and youl be movin... You will probably need some type of fuel computer though, but ive heard bad things about the AFC like the apexi safc... I wouldnt imagine it would do much harm if you just do mild tuning with it though.
