saw this in action, sounded sweet. As usual iphone went flat in 5 mins even though i was shifting in and out of airplane mode to save batt life and i couldnt video an fd3s drift car doing its thing on the time trial hill / road . Not seen a car drift up the hill there yet and it did it in style, pon the rotary!!

the plaque was wrong though, said it had only one rotor and made 247 bhp!!

Seen with my own eyes, couldn\'t believe it!

hey peeps, bit of slow progress lately, i could do with a bit of turbo advice please - basically i have sussed out what my turbo is, the part numbers trace to an 02-07 bentley turbo arnage.... i mean come on, of all the turbos the previous owner bought for it!!! anyway from what i understand its part of a tb0303 series , numbers are pf100647pf - 713333-3 - 1A12235B .

The bit i am not sure about is the chances of being able to get a exhaust turbine housing suitable for it in T4 guise, I phoned one turbo company up ( one of the recommendations  on here ) and he didnt even want to get as far as these numbers i quoted to try and advise me on a housing. He wants to see the blower . Luckily they are in hants so i probably will make a visit but before i do this i just thought i\'d post up here.

Ive got a funny feeling due to the odd turbo they are going to say im better off starting from scratch, which then leads me to possibly new turbo advice. What would you peeps recommend ? I dont want a large blower as its just not needed in the size n weight of my death sled but at the same time am i going to be able to find a small enough turbo for my engine as these rotary lumps breathe a lot more exh gas compared to normal piston engines?? Is it just going to be a case of buying a bigger turbo and run low boost?

I want it to be usable power , not mid corner catherine wheel syndrome on track days!

Sorry if i didnt explain this clear enough or waffled on too much, im not up on turbo jargon - go easy on me ...

That\'s enough for me , you can read too much sometimes on Ze net and you can fall short if it isn\'t gospel . I had a look yesters on your rx4 build - very nice bud indeed. Think I\'m ok for the moment on t4 flange . Think mines a t3 anyway but if I change the exh housing I\'ll prob be a tapping on your door ....

if its standard , fix all those issues and nip back to the testing station or any garage nearby and ask them to do a quick free measurement on emissions to see if the fixes you made has altered the mixture. If you had a hose off the intercooler that definately wont help. Most testing stations are ok and they would let you do a quick free measurment co check to see if you will be ok for retest. ( on a non cat test that is as it takes less thane 2 mins )

yea it was fun for the 1 week i had it on the road , rear diff was waaay too low so power transfer was even more wild! especially as it orginally ran 13\' rims with teeny 195 tyres. I was breaking traction up to 3rd in the dry and i never took it past 4.5k as it was only on base map .

Grant - Thought i read somewhere that mild steel is probably better for flange anyway as stainless flanges can distort easier? If that is true the rotary engines would certainly show this up . Thanks for the contact , ill have a butchers :-) once again peeps, thankyou for the input

Grant, that pic with that gargantuan turbo setup you used on the rx4, what  steel is that?  Can you buy those custom flanges/ plates anywhere in the uk? Think my one may let the rest of the materials down in terms of quality

Me extra tubes, wasn\'t far off in estimations, 270 mm and 480mm!

reputable turbo specialists is my next port of call then - any reccommendations?

splendid. I just popped into my mate at the fab shop and he just dug me out two sections of same wall thickness straight stainless tube for me, one length bout 300mm and the other bout 500mm so should be all i need there, apart from making the bigger bit where the two primary pipes come together. My mate monkey is magic at this stuff, made me loads of odds n sods, never excepts any dinero so i always give him beer or turn up with some good chow. Or when his old tank merc breaks i pay the favour back properly

Oh while I\'m here, thankyou one and all for your help and input so far, just in 24hrs you\'ve helped tremendously in terms of enthusiasm & direction ;-)

Well the turbo is internally waste gated , either was going to do that sealed shut mod or chap at rotary shop in portsmouth said as it\'s a new garret blower to save money you could send off the turbo and ask for a different exhaust housing which doesn\'t have waste gate incorporation ? How compatible are exh housings ? If I could find a dead owner on evilbay for example and use the exh housing that would be a cheap way but I have little knowledge on blowers so I\'m sure I\'d buy lots of lemons before getting it right making it costly!

Deleted, poxy phone didn\'t update page properly and I didn\'t think last post posted up

So you saying if I run this 2inch tubing from manifold up to the turbo I could run 2inch post turbo? That smaller size would definitely help routing past the bulkhead as the 3" I was contemplating on using
