What do I need to run a safe setup for a Turbo kit on an S2000?

by

I’ve been doing my research for about a week as of now, and I’ve come up with an idea of what I’ll need.

I do not own an S20 as of yet, although its strongly going to be my next car, while I’m gathering the money for this endeavor, I’ll be getting a feel for the characteristics of the car sitting stock.

First: my goal is to have a RELIABLE 450 rwhp S2k.

1. I know I’m going to need a nice turbo kit, any suggestions? (what kind of injectors, I know those cause a lot of tuning problems)
2. I know I’m also going to need a EMS, and I’ve read a bit into the debate over the Greddy eManage and AEM EMS. Would I be better off going with the AEM from the beginning?
3. I plan on also setting aside about 2k for a better diff, as I’ve found those are supposedly made of glass. (sugestions?)
4. later on I plan on spending 2-3k for upgraded internals (since I know the S2k already has forged internals should I do this? if not pistons and rods what other engine mods would be helpful to retain strength?)
5. I also have heard of turbo nightmares, and stacks on stacks of months for tuning. Does anyone know a reputable tuner who has done many S2k turbo tunes?

Am I missing anything on this list?
I want to basically build the engine to handle 550-6 rwhp max, but since it would be a DD, I’d water it down to 450-475 rwhp.

If the F20/F22 cant handle this kind of power without reliability issues then what other engines are good for this swap?
possibly a 4G63…

  • Swap internals before turbo (change compression of the pistons to somewhere around 9:1 if you’re going to run that level of boost (20 pounds likely). Anything over go lower on compression. Stiffer valve springs and forged valves at the minimum. Bottom end should be okay if you keep the same red line.

    There will DEFINITELY be reliability problems with this setup. You don’t really need this level of horsepower in this car because it will require ballast weight because of the curb weight of the vehicle (it’s slightly pointless). In these cars I wouldn’t go over 325hp (somewhat less torque), that’s all you’re going to need…anything more you’ll need ballast weight or it won’t hold torque to the road.
