In a NA miata the average gain is about 30hp with a piggyback. But with ITRBs it's not about power but about response.

And sound! Oh GOD the sound!

Ah gotcha, but that's a pretty penny to pay for throttle response. I guess I just don't understand the whole concept since I don't actively track my s2000. :iono:

When you're tuning an NA, nothing comes cheap.

The only reason I'd give a thought to putting a turbo on the FT: Budget.

Well that part(which is all I found) is from Tomei which is a super JDM brand. That's why it's so expensive.

The kits made for miatas are around 2000.00 with the piggyback. I would guess about 2500 to 3000 would be resonable.

keep in mind, though, that we're likely going to be dealing with throttle-by-wire, instead of a normal throttle cable. that's going to up the cost significantly on any ITB kit.

Not really cause Cosworth developed a ITRB kit for the 2.3 and 2.0 MZR(Mazda) engines. When they use to have the prices on the website it was 2000.00 for the Individual Roller Throttle Bodies alone.

It's in this car...http://www.awrracing.com/allstar.html

I had ITBs on my miata and there is no way, even with a full standalone you could make 30 whp.

However, ITBs on a subie sound awesome: http://www.youtube.com/watch?v=ctyBOEk3L9Q

Couple that with a disco potato and stick a fork in me i'm done :p

Yeah, that's what alot of S owners have said. It's almost cheaper to boost it than go NA. That makes no sense to me. More power for less money.

Ask anyone who's boosted a factory NA car, though, and they will tell you that boost does not come without its own set of problems. Especially in the realm of engine management tuning. Then there's the problem of the engine being too capable for the chassis, requiring even further (re: $$$) upgrades.

yeah but there's also a whole forum dedicated to NA tuning on s2k. talk to the guys there and you'll understand why it's worth the $ for some.

Not gonna jump the gun on this one, for all we know it could be a very responsive and somewhat powerful engine. That and I probably will just throw all the money into wheels and suspension/handling. :word:

Amen, 2.5RS problem is high boost. If you're doin' +8psi without proper internal tuning, expect the engine to blow in few yrs...

That's why, I was saving up my $$$$ to do H6 engine swap on my RS... til FT-86c came along.

From what I've gathered, thats about the same psi range for any NA engine turned turbo.
