Well what can I say?....
LOL
That\'s all.
This is one poorly car :Laugh
It\'s not too bad and is saveable but ilhave I found some issues.
No boost pressure. Ive reached down to the actuator rod and have found massive amounts of slop in it but due to those clever engineers at Mazda hiding the blower in the most awkward place ever, I can\'t confirm wether the actuator is screwed or just the arm has popped off the wastegate. At least until I get it on a ramp and view from underneath. Someone has clearly attempted to play with it though as the heat shield is loose and only held on with one bolt.
The radiator has K-seal headgasket fixer in it. I\'m guessing to cure a leaky bottom hose but this may prove to be more sinister.
The heater fan works fine but has no direction control. I assume this is due to a small section of the trunking that I found in the armrest :Hammer
Also in the arm rest was a screwdriver and wood screws so I have no doubt that some part of the car is fixed together with wood screws. Nice
Whilst driving there\'s a fair smell of fuel occasionally which is probably a leaky vac pipe or similar. Is there a common problem along these lines?
After a decent journey there\'s an oh so refreshing smell of gear oil entering the cabin. I have found a leak yet but this also requires further investigation.
The paintwork.....
LO f***ing L
Surely painted by stevie wonders guide dog with a cannon. it\'s truly immense :Laugh
I feel sorry for Ben who I bought it from because whoever took £1400 off him for it bent him over good style.
There are probably thousands more interesting issues yet to be discovered but despite all of this I actually quite like it.
Oil pressure seems very good. 62 at 75mph and 45 at idle. The engine sounds sweet and there is a \'rotechnics\' sticker under the bonnet so I\'m going to see if they\'ve done any work to it in the past.
It\'s a turd but I\'ll put it right.
Cheers for now
Ross
Sounds like a beast!

I think I may be needing a fair bit of technical knowledge off you guys in the not too distant future so please be patient :Giggle
Ross
Welcome, to the club seems like you\'ve got yourself a minter!! :Giggle
Best of luck fixing it, I\'m sure there will plenty of technical knowledge available to you from the folk on here. We even have our own in house FC guru, named Prof! Best of luk with your project, sounds like you\'ll need it. It\'s great you are saving another FC from the junk yard.
Ben
sounds like you have your work cut out :D
Yep, from now on that car will be known as \'the minter\' lol!

This is a fairly common problem and yes the actuator arm has most likely popped off. Worst part of the fix is getting the heat shield off. The arm is help on with a little C clip
The radiator has K-seal headgasket fixer in it. I\'m guessing to cure a leaky bottom hose but this may prove to be more sinister.
Again fairly common. People run K seal in the rotary in case the engine develops a water seal leak, not in case a pipe splits. I do this.
The heater fan works fine but has no direction control. I assume this is due to a small section of the trunking that I found in the armrest :Hammer
See below
Also in the arm rest was a screwdriver and wood screws so I have no doubt that some part of the car is fixed together with wood screws. Nice
Not really sure on this one. Maybe try No More Nails!

Yep RX7\'s stink of fuel especially when boosting. Don\'t worry it\'ll only hurt your wallet

As you say further investigation needed
The paintwork.....

Just squint when walking to the car. When your in it you can\'t see it so much.

Hope that helps

With the gear oil, maybe pull up the gear gaiter and see if the gearstick is fully secured down to the top of the box, there might be some ATF fumes coming from there which is then wafted up into the cabin at higher speeds as the air rushs by?
Is your car 100% standard?
Thanks Ade, you\'ve put my mind at rest about alot of that there.
Mitch.. Other than a decat pipe and hks air filter it\'s stock and covered 101k
Ross
Pica are demanded! :D
Your welcome mate. There is a good bunch of Guys and Gals on here so when you need help just ask. I know I do!
The only other thing to add really is if the petrol smell is making your eyes water then investigate it further. Last thing we want is a rex on fire. But like I said above they do stink as a general rule even more so if its de-catted.
*UPDATE*
After swearing like a trooper this morning removing that damn useless piece of w4nk heatshield, I\'ve found that the actuator rod has indeed \'freed\' itself from the wastegate :rolleyes:
Unfortunately I have no circlip of the correct size so will be attaching a blob of weld to the pin on the wastegate arm later to hold the sucker down.
Hopefully there will be much of this :3gears-lh this evening.
While under the car I\'ve also spotted a stainless downpipe (roughly 2.5") and a decat plus some unknown lowering springs.
Although not making boost I\'m still loving the car and thinking that even an EGI must be fairly quick. And if naturally aspirated rotaries are quick then a gen 1 might be a future purchase worth considering. Infact I\'m really wanting one now!
These weird wankel boxes may get quite addictive.... HELP :Viking
Ross
Depends what you class as quick, i went from a Nova GSi to an egi and felt a bit dissapointed by the lack of speed. Now i\'ve driven the T2, to me it doesn\'t \'feel\' that fast but then when i look at the speedo i realise it must be because i\'ve been used to driving hot hatches which weigh about as much as a lunch box. Then why you urinate all over something like a Integra Type R - which are spoken of as pretty \'quick\' i finally realise i have a propper car now :Giggle
Ross, It\'ll be a different car altogether now. Glad you\'ve got it sorted. I ended up cutting the bottom half of the heat shield off so I can get access to the actuator arm easily in the future. Plus one of the bolts snapped when I was taking it off!
He\'s truely one of us now :Giggle
Quote from: Brett;782670He\'s truely one of us now :Giggle
Yes.... Frustrated.
After :censored::censored::censored::censored:ing around under the car with the trusty mig and a pair of mole grips for far longer than it should have taken I finally got the arm on and welded. However, next to no extra boost! I reckon the actuator might be shafted after all. The boost guage is only rising to the the 2nd block at best and that\'s not even all the time.
What should the boost guage rise to and what does that equate to in either psi or bar? I may try a spare ebc I have kicking around and see if that can liven up the old girl. I\'m not expecting it to be as quick as my gtr but it just lacks that punch although it revs nice and strong and has a very linear feeling power curve.
Off topic but is anyone else on here around Lincolnshire?
Thanks again chaps
Ross
Maybe a knackered actuator. Think I\'d be checking all the hoses for splits first though (if you can get to them to check). If there is a leak on the hoses to the actuator it won\'t be working properly.
The stock boost gauge should read right throughout the range under various conditions. If your only getting minimal movement then there is defo something wrong.
There\'s also a better than average chance the stock gauge has failed.... They do that :/
Do you have an aftermarket one?
unless there is a FCD fitted and you wont see much on the stock gauge ( im sure it stops working when you plug one in )
Mine seems to work perfectly fine? I\'m sure I don\'t have an fcd?
I\'m thinking it is now a buggered guage as I took it for a drive last night and it did feel quite quick and next to no movement on the guage. I can hear the turbo spooking away and chuffing back through the airfilter and the speedo is certainly moving rapidly enough.
I think it was all in my head as I wasn\'t seeing boost on the guage.
There could be a few electrical gremlins with the gauges and warning lights on this car as when I dropped the beast (wife) at work this morning an alarm sounded and a picture of a radiator illuminated in red on the dash. A quick check revealed a full rad and expansion tank and a perfectly healthy temp reading. As soon as I set off it all went out again.
Do I know how to purchase quality vehicles or what!!

Isn\'t that just so true :cheers
Welcome to the club chap - and good on you for saving another Vert. I rescued one recently without an engine -originally to cut up and patch my rotting shell, but it looks like I shall be moving my goodies over to it instead and finally bringing Rixxy I to a close.
With boost these cars are awesome - and the vert often catches people out because they don\'t know what these things have under the hood.
Good luck with the wastegate \'fix\' ;)
Sounds like you got earthing issues - they can plague the FC :(
