Mazda Rotary Club

Hi all....

As per the title I bought my first RX7 about a month ago.

The engine is standard apart from a Blitz exhaust. I have bought a used Apexi from reading info on this forum. Guessing I will need an induction kit.

Question I have is.....are there any decent rotary specialists near Birmingham? Would like them to advise what I need to get more power, fit and map  the Apexi etc.

From what I have been reading... Powergains is good but based in Essex. Also come across WGT autos in Cheshire which is nearer.

Any advice?

Hi mate, they've been around for years and years......and probably the complete 1 stop shop for Rotary in the Uk. got a dyno too. Never used myself as i use Hayward and RX motors as im down south. Based on location wgt are 2nd to none....there not cheap but ive never heard a bad review.

get some piccys up!.

what sort of power you after? im on twins at 14psi still sequential, max the stock turbos can really handle and circa 320bhp...which in such a lightweight car is plenty.

prob best to give them a ring and discuss your requirements, you probably need a free flowing downpipe to get more power and possibly and uprated intercooler...if still on stock. it all depends what you want todo with it, if aimimg to go on track it gets a bit expensive as heat is your enemy in a rotary and need ancillaries that can handle and manage the heat like decent radiator, vented bonnet etc.

I’ll get some pics up soon.... car needs a bit of work.

Eventually I would like 400-500bhp which in a lightweight RX7 should be phenomenal. But need to find out what’s involved especially in terms of cost.

I definitely don’t want the engine bridgeported. Been in one and don’t like the noise.

Guessing I will have to go single.

Car won’t be used on track. Just the road.....like the idea of having power on tap.

ive had 2 fd's both twins, 1 was at 16psi and very quickly fried the turbos, well warped them...circa 380 bhp scared the life out of me ha ha, i will go single 1 day but there working fine atmo so ill stay as is...but yes id like a cheeky twin scroll turbo...i dont like lag and the twins come in low down and keep on going...i drove a mates Starion years ago and that had so much lag it was horrible...

Called WGT.... they will call be back shortly with costs. I’m going to sort out the interior, wheels and a few little bits and pieces first.

 :welcome: to MRC and as you will have already seen, we will help with advise if we can and yes WGT will give you good advise and tune your Apexi no problem.

I have known Pip for many years and he looks after the mapping on my FD engined race car. :great:

Thanks....

Are there are traders on the forum that sell used RX7 parts?

Thats a question !
There’s many ways and mine wAs over many years and half of it by previous and there’s people on here can advise.

When the water meth was fitted they welded into the greedy elbow which left bubbles of weld which eventually broke off and destroyed my rotors and housing.

I’ve just bought a new engine as it was cheaper that a rebuild form sliver  firm performance , had the new engine street ported and all reinstall back to how it was , which has just cost me £8000 I’m just running the engine in at mo on a low powered map before taking it to wgt to have it retuned back to full power

That’s nice. Must be an absolute weapon.

I would like to get to that stage in the future.

Your build.... surely you have upgraded the clutch. What big brake kit did you go for?


Sent from my iPhone using Tapatalk

Its crazy fast at full power

My link ecu as a map switch so map 1 is 350 bhp and map 2 is 500 bhp ... or will be again once I have run new engine in.


It has a race clutch but I don’t know which one as it was just installed new when I bought it and was put back in with new engine ... will find out

D2 brake kit front 356mm 6 pot

Before you start converting best to get compression check done on engine so u get a idea how healthy it is, worse thing in the world when you spend a lot of money upgrading to find the engine dies not long after ☹️

Need some advice guys....(https://uploads.tapatalk-cdn.com/20180822/a68145bf229041f09d55a149f737c587.png)(https://uploads.tapatalk-cdn.com/20180822/4814f0575398eb1b6a7d9b1e7e5197d3.png)


If I go for a few simple mods like Apexi FC and inter cooler etc.... I might hit get around 320 bhp with the stock twins. Or I could go with a single turbo conversion for circa 5k and achieve around 450bhp with EFR turbos....

Worth it???? Seems a lot of money for a little increase.

I like the twins, no lag.. less stress on the rest of the drive train...upto you im sure id like 450...lol...but im happy with 320 and it flies on track.

I won’t  be using the car on a track. Just the occasional weekend street use. Would be good to hear from others who have experienced both
