Single Turbo or Twin Turbo?
Hello I have a 92 FD3S twin turbo and I'm wondering what is better to have single turbo or twin turbo? I have started to take the engine out the car since I lost compression in the back rotor. I will be rebuilding and upgrading lots of parts but not sure if I should stay twin turbo or go single turbo. I eventually want like 450-500hp and don't know what to do with the turbo setup.
Any help and opinions will be considered and greatly appreciated.

If you are looking at 450-500HP, then you'll be looking at a single turbo upgrade.
There really is no "better". Generally single turbo setups are far easier to set up, don't lag, and will make the power numbers you want.

being a noob here myself (just joined today)....i would wonder the same thing. im trying to learn more about these engines. dont know much about them.
i own a 93 jdm surpa....and in the mkiv supra world there are 2 engines. the 2jzge (n/a) and the 2jzgte (twin turbo). some ppl take the n/a and add turbo making it an na-t. those w/ tt are removing the stock turbos and are going with larger single turbos for huge hp gains. my question is....is it similar with these rx-7 motors?
thx in advance

Top Down, Boost Up

Sort of. It's all in the quest for more power. Any turbo (or pair of turbos) will have airflow/power limitations. If the person wants more, then the only option is to go bigger. The issue is as you go with larger and larger turbos, the powerband shifts up, and will become less useable on the street. Sequential twin turbo setups, divided manifolds, ball bearing turbos, etc... are intended to help build boost quickly so you don't have to wait so long.

Adding to the above comments, the 3rd gen FAQ has a good comments on what is involved to reach each power level
