The Full Frame

This is my review of the Esmeril Racing Turbo Kit for the Mazda RX8

http://esmerilracing.com/

I bought this kit during the Christmas special of 2007. I purchased the kit for $5000 without engine management. At the time of this purchase this was the single most powerful turbo kit that one could buy for the RX8.

Track Review

So I did a track day today. I had to call it quits since my gauge pod came off my dash and was flopping around, making it difficult to take corners whilst trying to hold the gauge pod. I did get a good impression of the kit though.

Ambient = 60 degrees.
Session run time = max of 20 minutes.
AFRs = tuned to 10.2-11.0 @ 10psi
Tires = Azenis RT 615s, 30% thread left.
Max track straight = 1/8 mile

Well, there was a little smoking (small puff from under hood) as the heat shielding got further settled into high heat use. I did a nice warmup lap before I got her into boost before every session.

Cars I murdered on the straights (couldn’t catch me, I just kept pulling away):

C5 z06 vette
another c5 z06 vette
04 GTO
Elise
R32 Volkswagen
G35
s2000
05 M3

Watching me pull hard from a vette is truly an exhilarating experience. Truly this power/weight ratio is something to be reckoned with! (continue reading…)

After getting it out of the box the first thing that came to mind was: perfection.

All the welds look amazing, there is not one flaw in the craftsmanship of this item.

Overall it weighs about 7 lbs by my guess.

Here are a few pics to tantalize. I will install this when the weather gets better here. Granted the real test won’t be till I get a 95+ degree track day in as of right now I would feel comfortable paying much more than this radiator sells for. Truly is a work of art, from the welds, to the material, to the size and build.

Just sitting there it screams performance!

In comparison to the stock radiator:

• Thicker
• Less fin density (fins spaced apart farther)
• All-aluminum construction
• Better performing

This is a griffin source design. Griffin makes very high performance radiators for circle track and NASCAR applications. http://www.griffinrad.com/

FEED 4.77 final drive review:

Getting the parts required for this has taken me around 3-4 months.

I bought the FEED gear used from Murix, great guy. He said it took him 3 months to get from Japan new.

$600

Can be bought new from http://www.mazdaparts.com for $677 plus probably $50 in shipping

Then I had to get the Mazda bearing Kit, which are the two bearings for the main pinion, the two bearings for the axles, the three oil seals, and the crush washer.
