I can vouch for an MX5 pulling 150rwkw on the rotrex kit on stock internals and it hauls ass
with the risk of offending, running a SC on anything requires strengthened internals if you are wise & expect the engine to have any longevity. Yes, lower boost is one way to counter the higher comp' of stock engine but, the MX5 stock internals aren't that great. The rods are stock.

I thoroughly went down this road about 8 months ago. Found all the info I could before ever considering between the 2 for the MX5. Supercharger or Turbo? This is a debate that will go on for ever & is actually frowned upon on @ least 1 MX5 forum, for risk of severe offense & potential for heated arguments. The subject requires all the information be laid out on the table. I relentlessly searched forums, documentation you name it!

A SC on anything smaller than a 2.0L has one large obstacle to overcome.

It saps power/uses the engines power to operate. What this amounts to is it takes power to make power. Running off the crank it places aggressive load on the bottom end internals.

In simple terms. What this equates to is say you want 125wkw out of the vehicle. You need to allow say, 15kw to be sapped within the crank action.

If you want deeper info then you need to research the facts from experts not just 1 persons application

Btw, alot of SC vehicle owners ditch the SC for a big-ass turbo properly set up. They get the strengthened internals afforded by the SC factory build as a bonus. Factory SC vehicles have stronger internals than a comparable factory TC one due to the stress tolerance differences between the two. A good example can be seen in the MR2 4AGZE engine. Reknown for strong internals. Again, some have opted to swap SC for TC. It's all about application/$$$$/choice.
To be fair, SC's don't need the hassle of oil feed/drain lines & risk of a line blowing & root-ing the turbo etc.

this is precisely why a SC requires stronger internals. The turbo is only working hard @ higher revs (above 2500 for arguments sake) whereas the SC places load right @ the beginning @ low revs. Also, you can get a turbo to spool with near negligible lag if you do it right Once it kicks in it can boot like a mule & it's then that it places the heavy load on internals but @ least the engine is already climbing the rev-range nicely

In the end. It's choice. I like both FI applications. As long as they're set up right. Look @ the hell I'm forced to go through with the Merc @ present due to seller having engine built by dodgey half-wit workshop. Basically, they set it up to destroy itself! It was doomed from the beginning & they probably still don't know where it all went wrong. But I do!

Did anyone else notice that one of the first pics is a ford engine??
Do they make these for any smaller engines? I doubt it.

Well I got a reply from AAI:

Quote:
Dear mate

how are you? regarding to the item you after, we could import it for you, which is AUD$4350 without ECU or AUD$5000 ECU included, it's included EMS shipping cost and import tax, please feel free to email us for further information thank you.
So take into account the relocation of the clucth brake booster, youd still be up for $7500 if you wanted to upgrade internals too, but $5k for a complete kit shipped aint bad

Here is a link for the supercharger used in the kit as far as I can tell. Well its the same company anywho.

http://www.oguraclutch.co.jp/english.../sc_gaiyou.htm

This kit combined with an awd package would be awsome if the engine was worked a bit

So a Sport20 most likely sourced from NZ for cost reasons, supercharger kit, some tougher rods, and forged pistons and itd be a goer

I don't think that you would need to source a Sport20 from NZ these days just to save money. SP20's are cheap enough at the moment , just buy one of those
