Parts for sale / BREMBO GT big brake kit (Enormous)
« on: February 03, 2015, 11:37:22 AM »
Hy Guys,

I have a brand new BREMBO GT big brake kit laying around which I have decided to sell. Due to other priorities (own business) I'm not getting around to use it.

It's a BREMBO Gt brake kit, originally for a Hummer H2 (2003-20074), brand spanking new in the box. It consists of

- 2X  BREMBO 6 pot front calipers with new Brembo brake pads with adaptors for H2
- 2X  BREMBO 4 pot rear calipers with new Brembo brake pads with adaptors for H2
- 2X  BREMBO slotted front brake discs 380X34mm (2-piece)
- 2X  BREMBO slotted rear brake discs 380X34mm (2-piece)

All bits and pieces included to bolt these on.

Kit can be adapted for other cars by changing the caliper adaptors and discs centers.

PLEASE be aware these things are enormous so you will neeed at least 20" wheels for it

Ideal for show car.

Newprice is above 8000 euro (rear kit alone goes on the net for mare than 4000 euros)

Asking 1800 euro for a quick sale.

I'm in Belgium, please mail for quick response as I'm not on a daily basis on the forum.

General Technical / UK Alloy wheel quality certification
« on: January 28, 2014, 10:09:47 PM »
Hello there,

I was talking to a UK alloy wheel manufacturer (Wolfrace) and more importantly if they could provide paperwork/ certification or anything like that (similar to German TUV/KBA/ABE or Japanese JWL) with regards to quality control, axle load etc.

So far they informed me to have none if all and stating in the UK you don\'t need it. Weird...

I could imagine the UK market is to small for a wheel fabricator and they would export to countries that do require some kind of certification/testing.

More importantly as Wolfrace\'s website states to be Rial and Alutec alloy wheel distributors for UK and those are German wheels (incl. certification).

Does anyone have any info on this subject,


3rd generation RX-7's / Max disc diameter for 18" wheels

General Technical / 20B ECU... what&why?
« on: July 20, 2013, 11:45:07 AM »
Bringing a question here that I posted on RX7club some weeks go...

I\'m planning a 20B conversion for my FD and one of my main concerns is the ECU.
I know, plenty of choice in principal but as we all know, 20B conversion are not cheap and finding a good Quality/price product is a must.

Also taking into account to have a decent tuner in the (more or less) direct region for tuning.

Some posibillities have crossed my mind...

-Microtech: LT12 version seems commonly used in the US and UK but main remarks seem to be the outdated hard and software, making it harder to finetune and the ECU lacks additional in and output channels for fe. wideband, EGT etc.
Price wise probably one of the best buys

- Halltech/Motec: Putting these on more or less thesame level for price and function. Still in higher category

- AEM: seems to be used from time to time in the US. Less people over here that are used with it

- Pectel/Cosworth: seems to be top rate but top price (4000USD+) as well. I know someone who has a Pectel ECU on his 20B and has nothing but good on it

Feel free to add or commend, by preference your own experience with one of these ore others.


3rd generation RX-7's / Upgrade brakes for
« on: May 31, 2013, 07:02:58 PM »
Hy there,

bringing up an old sore of mine. Over the years I have had different caliper sets (AP, Brembo etc), but as rare as the FD is in our regions, little is plug and play (except for Japan/US import items).

As the calipers currently in my posession are top notch, I want some discs to match.

With the upcoming trend of OE car makers to have high end brakes (drilled/slotted/etc) I was wondering if there is something out there that can be used on the FD (given a redrilled bolt pattern).

Merc/Audi/BMW (others?) must have interesting parts we can use.

Any body that has tested or tried one of these?

Please share!!!

RX-8 News and Information / Looking at a RX8 with starting issues
« on: January 12, 2013, 11:03:50 AM »
Hy Guys,

I\'m more of a RX7 fanatic (since 2004) but recently I noticed a RX8 near me which might be for sale soon. As it has been sitting in thesame place I got in contact with the owner. He told me he got it from a dealer and drove it for only 60km\'s.

After a short drive he put it away and the enxt time she wouldn\'t start any more.

Have done a quick search on here and ignition coils seem to be an issue that pops up many times, apparently the starter motor is too.

Any other issues that you could point out?

OWner says he needs a new engine, but considering that the car was running fine upto this point and he probably didn\'t abuse it on his first drive, I guess it might be a different, faster to solve, issue.

Compression issues would be sooner to point out as the engine would be harder and harder to start over certain period of time. Not something which occurs al of a sudden.

3rd generation RX-7's / Urgent electrical help req!
« on: October 01, 2012, 06:08:23 PM »
HI guys,

After 2 years of rebuilding my FD (2nd time) I\'m about to start it up again.

Though some electrical worries are holding me back, so I need some urgent help.

1. wire coloring.

- Knock sensor
- oil pressure sensor
- water temp sensor

Basically everything that is on the wire tree running from the fuse box to the starter motor. Somehow connecters broke off and I\'m having a hard time finding the correct wires.

I have an OEm workshop manual but there is no clear wiring scheme on that section.

Furthermore, I want to start it without the ignition on to build some oil pressure before firing it up.

I need to retract the fuse/relais for that, that\'s the green 40Amp fuse near the battery, right?

Many thanks!!!!

3rd generation RX-7's / Q: mass cable attachment
« on: September 09, 2012, 07:29:55 PM »
The cable tree from the battery to the engine (ignition etc) to the starter motor has a faurly big mass cable (black with yellow tripe).

Does it attach to the chassis or the engine?


Anything Engine/Performance/Tuning related / Big brake thread
« on: August 23, 2012, 08:07:32 AM »

I\'ve been on here for years and a lot of Q\'s about bigger/better brakes have passed. From upgrading to 99 spec items over custom built kits by rotary companies as well as put together sets.

Overal, the first 2 are quite expensive, so over the years I have been contemplating alternatives as I am in the possesion of several big brake calipers (AP Racing CP5200, Brembo\'s, etc)

2 issues always appear...

1. Caliper adapter... could be solved if you\'re a metal worker or know someone.

2. What brake disc to use? If using 2-piece items... off the shelve items are rare as few companies ever made RX7 (FD) specific items.

Alternative could be to use standard items of higher end cars... to name a few... Audi R8, (R)S 4 or 6, Jaguar, Porsche and similar. You would just have to adapt the bolt pattern to 5X114..3 (if even that, depending on the car they are coming from)

I could imagine that \'normal\' steel discs would still be quite reasonably priced.

So, what are your thoughts and experiences? What brake disc from what car would you recommend price/quality/resourcability wise?

I have a Brembo big brake kit (not FD3S specific) laying around. I just need to have brackets made for the calipers to fit.

Does Brembo use a universal bolt pattern on their calipers?

As there are company\'s/racce teams using Brembo calipers on FD\'s They might suit my parts as well.

Wanted Items / FD3S suspension
« on: June 13, 2012, 11:29:32 AM »
Hy there,

I\'m looking for a good suspension alternative to replace my current one.

Current: New Koni Yellow shocks with Ground Controls coilover conversion (with Eibach race springs), height and hardness adjustable. (Everything has under 2000kms)

Problem is that the Eibach springs are too short and had no helper springs to keep them in place when the wheels are of the ground (It\'s a Belgian MOT rule that springs keep a fixed position, don\'t ask me why)

I already added non-preloaded helper springs and spacer, but still it doesn\'t give me the right feel and MOT is\'nt happy about it either.


I\'m looking for something else:


- height adjustable
- stifnnes adjustable
- low mileage
- prefer a known brand (Tein, HKS, ...)
- Needs to have main and helper springs

Car is used for street and track
