Rotorstock casualty, i need a rebuild! But which way to go...

[Donato]

I have been speaking to Carl, (again very big thanks Carl!) and have been given a good idea of costings if decide to do this myself. Using new housings and replacing all gaskets/seals.

I think i will stick with the twin turbo set up as mid 300\'s is enough for me, and perhaps go for a mild to medium port, upgrade to a Apexi ECU and possibly ceramic Apex seals.

I have a couple of weeks to think about it, speak to the experts and make a decision, to be honest i would really like to do this myself as i have rebuilt piston engines before and would really like to rebuild a rotary.

General consensus on the ceramic seals is that they\'re only of real benefit for very high rpm applications (and you need to get a balanced crank shaft + other stuff for that) or high boost apps.

For the extra money you can be half way to the next rebuild!!!

Donato, if you want the car to be quiet do not get it ported.  I only mention it because you did say (when discussing mods) you were not wanting the car to be too loud.  I also wouldn\'t bother with ceramics.

If you are planning mid 300s you are going to need more of an intercooler than you\'ve got, or run WI.

Hi Robbie,
It was a shame I did not catch up with you on Monday.I would have liked to have shown you my really quiet back box,and demonstrated it too you.
I agree that you shouldn\'t have had ceramics in your engine Robbie,you have never really had the mods needed to justify them so far,Geff said at the time of the rebuild that you were intending to mod your engine ancillaries much more than you have so far.
More controlled boost will make them worthwile.
Also the porting does not make a car louder,the exhaust does.
Kind regards
Carl

Its in the pipe line

Carl, I ran the stock exhaust with the stock engine for the 146 miles it lasted and it was deadly quiet, then with the only change being the rebuilt ported engine the volume level more than doubled.  Anyone who heard my car with the ported engine and stock exhaust - Rich, Max, Gary, John, Bob, etc will testify it was much louder than a stock engine with stock exhaust, as Donato has.

The ceramics will be tested to their limits as soon as my turbos make it into the UK, it\'s just been an absolute nightmare trying to get the things.  Have now fallen out with TNT after they failed to collect them twice with no reason, so fingers crossed the supplier will be shipping them tomorrow and I will get them next week.  It has gotten to the stage where by I have been looking at getting a return flight to the US so I can collect them and take them back in person.

If I hadn\'t had problems with getting practically every bit for the car it would have been running its full spec long ago, but as it stands my car has spent longer with my mechanic than me since I bought it 18 months ago.  Rest assured 1/4 terminals will be posted up the first weekend after it is in one piece

sorry to hear it mate, looks like I was not the only casualty.

ported single turbos are amazing, well i like mine, just a shame i have to sell her

[Archbish]

I think that was from last year, dude...

[Donato]

Hi mate, this thread is a year old! at least i hope it is!! :rollin

[nikp]

Well, I found it interesting reading anyway! :p

So, did you eventually rebuild your engine yourself, and how did it go!?

[Donato]

hee hee,

i removed the engine and sent it to pip for rebuild and porting, i then fitted it back in with non sequential turbos a big fmic 1300 injectors PFC etc its now running 300 at the wheels and got a 12.9 up the strip at rotorstock this year it did 21 runs in total and has done 50-60 laps of knockhill so far this year, has proved its reliability i think!

[Steve Burnett]

Ive just spent about 10 minutes reading all of this only to find out its over a year old.
Glad for you Donato after thinking that you did loads of runs at the weekend with no problems that I had heard off!

Next time I\'ll look at the date of the original post!!!

[nikp]

Not bad at all! Pretty impressed! (Decided not to do the rebuild yourself then!? )

Thanks,

After i had done the maths, doing the rebuild myself would only have saved me £500 and then i wouldnt have had a the piece of mind of a 12month warranty from Pip....
