Hi guys,

I have a 94 model year car and im ready to make my FI kit purchase :) and the FFS is one of my two serious options im considering.

First off, i do a couple of track events every year so reliability is key for me and i definately dont want to be the one to pit in because the engines pings or the car over heats after a few laps.

Ive heard a lot of stuff on the BRP mostly hotside SC's and a lot of them have had problems with pinging even on the street so im kinda worried. I know the FFS kit has had great reviews but the fact that the engine management provided does not offer timing control and works off the stock injectors is something that yet again worries me and i do not want to have to use race fuel when i head to the track, here we mostly have access to 91 pump gas.

I'd like to know more about the engine management options you offer that will offer optimal reliability. Also, what boost pressures/pulley/whp figure would i be looking at for track duty and street?

The car as it sits has

94 engine w/99 pistons (rebuilt engine)
crank scraper
mild porting
4-1 Headers
FM Cat
Borla single tip exhaust
Koyo 37mm race-rad

I love the simplicity of your kit, i love the fact that there is no silly looking intercooler, it apparently runs like stock and its cheaper than the other option im considering but there are less features as well. Please help me out with my decision! :)

What are your shipping delays these days?

We are running about 10 days these days due to an inrush of orders.

You can expect ~190-200WHP on 91 pump gas with our base kit. Personally, I wouldn't run a stock Miata on the track on 91 octane. Running a boosted Miata with almost double the WHP (turbo, hotside or coldside; intercooled or not) on 91 octane is not a good way to treat the engine. I would hope the poeple selling the other option, if at ~200WHP, would advise similarily.

As others will tell you, coldsides are a blast on the street and track with reasonable fuel or fuel additive. $6-$8 worth of fuel additive to a tank of 12 gallons of 91 octane on a race day would be cheap insurance.

Any recommended brands of additive?

Torco comes to mind. ;)

I got mine from S&W racing but they charge heavy $$ for shipping. Somebody found it someplace else that doesn't charge shipping but I don't recall where.
