If there are 2 people that would know, they would def. be Stephen & Rich
fdnewb. . . david garfinkle got his turbos from bnr. . . bryan nickle IS bnr. . . SO ,therefore, bryan nickle BUILT david garfinkles turbos. bryan nickle told david garfinkle that the turbos he put togethther were off of "some nissan" and that they "put out 500hp". thats what david garfinkle was told by the builder. . . that that would make bryan nickle the ONE person that would know.

Paul,

1) So, do they really put out 500hp on an FD??

2) I thought this wasn't a custom application for just one customer... I thought it was something Bryan was thinking of making available to others, which in that case I'd assume Rich & Stephen would know about it...that's all.

Lightbulb hey

Everybody is forgetting about the rx7 FD3S that was sold in Australia and raced in Bathurst race track against 911 porshes with twin parrallel turbos.

Mazda Australia had to make a production model so it could enter the races in Bathurst, they had two models one SP1 and SP2, im shure about this and the FD3S ran two Hitachi turbos that was originaly produced for the 20b Cosmo.

They had very good results in track racing with good lap times too.

If im not Mistaken the SP2 model won for three years until Mazda dicided to stop racing.

Thats Why Mazda Japan had a Limited edition called Bathurst Edition some of you might have a secand hand one imported from Japan already. the Japan Buthurst Edition was identical to the Efini but labeled and some little extras if im not mistaken.

To get to the Point it was the Australian Edition SP2 that had the Special IHI parrallel Turbos from the 20B motor Plus a very different body kit and carbon Hood painted to match the Body all SP2 where White in Colour.

If it won against the Porshes with the parrallel turbos it was made for a reason and i think the twin turbo setup is the way to go

Just to elaborate on what Power Put said, from the RX7 History page... (http://www.ttrex.com/RX7History.html)

"The 3rd generation RX-7 hasn't rested on the reputations of the prevoius two. 1992 - 93 - 94 - 95 victories in the Bathurst 12 hour endurance events against the best Porsche (open cheque book) racers (944 - 968 - 911RS) & other reputable sports car entries has showed the the world how Mazda's little 1.3 lt rotary engine could outclass the best from Europe & any other country bidding for it's glory."

"In 1997, the limited edition RX-7 type RB Bathurst X was introduced. It is based on the Type RB, and it is equipped with red leather seats."

"In 2001 came the new special edition Type R Bathurst, based on the Type R, the RX-7 with the lightest power-weight ratio. It is equipped with custom height adjustable dampers and fog lamps. The name BATHURST was chosen to commemorate the Bathurst 12-hour car race in Australia, where the RX-7 was victorious for three consecutive years (1992-1994)."

Oh and Power Put, I couldn't agree w/ you more: A twin turbo setup IS the way to go!

FDNewbie do you know any more on the SP2 the size of the turbos and how much HP they made we know they are from the 20B Cosmo, but what size,bhp?

Anyone has a 20B cosmo with stock turbos answer this one ?

I don't, BUT I know that the Cosmo twins have smaller compressor wheels than the FD twins, and they're only made for low boost (like 6 psi or something), so I don't know why they'd ever use them. That, and the website didn't say anything about them being the Cosmo twins...

When Pettit makes his Banzai w/ the 20B cosmos, he has the turbos balanced, blueprinted, and ported (or so I've read from my thread in the 20B forum)

FD, all i was doing was saying that the info from the maker is the most reliable. . . rich and stephen may NOT know. theyve never talked about what turbos are on davids twins before. . . just that they are special. . . and about doing that same kit for others. . . i assure you. . . once they see what goes into making them fit "right" theyll have second thoughts. . . itd take a serious "fabber" to do it the same way.

Paul, you're right...I remember now Stephen telling me how Garfinkle got them to fit specifically because he's so good w/ fabbing...and the amount of custom work was incredible.

Dumb question here, but are these the same T-28 turbos that are bolt-ons for 2nd Gen DSMs? I was looking at upgrading the stock T-25 on my Talon to a variant of T-28 so I'm curious...

the bathurst and bathurst x models are nothing like the SPs. Instead of having extras, the bathurst models actually had LESS goodies than a standard FD - they were actually sold as an 'economy' model, and in most production runs, were significantly cheaper than the rest of the range. The 'japanese SP' was the 1020 M2 - which was prototype only.

I'm currently working on a twin t28 setup. Fabbing the manifold is proving to be quite a challenge. Not much about the turbos yet, but some photos can be had at

broken93, it looks great. All that hard work will pay off when you finally get to drive it. And since you are doing it yourself then you know its done right.
