For a full street NA build which one is better to mod? I'm looking to jump into the v8 world but not sure which is a better platform. Basically vvti and tuning comes to mind. Will also be running a MAP ecu.

You should run the AEM Supra TT standalone to tweak out the best from this big stroker NA. I have a connection to a master in AEM tuning. So if you're interested, you got the source. 350-400 rwhp and monster tq that rips the tires is doable.

Thanks for the links. I'm aware of all the motor building options out there but still not sure whether to go OBD1 or OBD2. I've also considered the AEM but the MAP ECU is more user friendly.

OBD1 or 2 isn't a problem when going with standalone. I've recently talked to 2 pro tuners on Map-ECU and Map-ECU 2. I almost went that way with my car this weekend. I found out the wiring is very complicated with the Map ECU, especially #2. If you can do it yourself, then it's not a problem. But if you hire a tuner to do it, the installation alone costs around $600.
The total at the end: Map-ECU2 ($675) + Installation ($600) + Tuning ($600) = $1875.
The above total made me go with a standalone for a little more $.
If you're looking into a piggyback ECU that has similar functions like the Map-ECU2 (Map-ECU1 is inferior to Map-ECU2), then I have a Brand New Split Second FTC1 made specifically for the SC400 with the wiring instruction. This Split Second can control fuel and timing. The nice thing about this Split Sec is it'll allow you to add 8 extra injectors. So your car will run like stock at all range with its stock 8 injectors, then the other extra 8 injectors will work when the car is under heavy load. That means you can use 8 extra stock injectors for cheap without buying expensive bigger injectors. It also has the Map Sensor just in case you're looking to boost the car.
I can sell it to you for the price of the Map-ECU1, which is $300. It originally bought for around $800. Please PM me if you're interested.

I see your point on why you went with the AEM. As for me I'd still like to retain my factory ecu with a piggyback for finer tuning. I havn't researched the Split Second yet but sounds interesting for the price. I'll have to look into it more. Does it eliminate the MAF?

for obdII we use F/IC's. We usually outfit them to NSX's. It works pretty good, the big issue is idle, you really can't control idle. Unlike other maf scalers (IE SAFC), is that it doesn't trick the maf/map signal. It actually adjusts the injectors, and it will also do timing.
