if your not porting id go gt 35r or 35/40 so it will be quick through the range like jaydee says,youll find a t51 or similar will be too big for your engine and youlll have no power untill it all comes at once then peaks

Brilliant news cant wait to see it on track,hopefully be a bit of FD in there too .

Definatley jump it connected to a good power source and compare crank speed to another car before getting to involved,
sometimes a hot starter cranks slower then a cold one so maybe compare the two,
unfortunately hot start is one of the most common signs of low comp,sticky seal or something,have you given it a hardish run?

What year is it,on most modern vans the ecu controls the fuelling at a set speed not rpm to control speed,

Though you can screw out the throttle stop to restrict on early tdi`s its not a great way of doing it coz you loose half your power in all gears.

Go to Carl Hayward rotary he and his team will help you out and,they are super friendly.
Don t go to wgt.

I thought WGT were good?

Shame the weather wouldn\'t make it\'s mind up shorts wasn\'t a good idea,top day though and good to see the rotaries in all different forms,and see some great cars collecting prizes though someone needs to knock Clive off the old school podium.

Would do mate if you were a bit closer but blackpool is a it standard ecu and twin turbos?
Did you listen for even compressions with plugs out as the way its idling does suggest
a chipped tip its quite a harsh misfire
I dont think its air leak as its too rough for that

Seems double dear to me for a non 99 but looks very straight so well worth a viewing,impossible to judge the car on pics and a write up maybe worth every penny if so would be a good fd for someone who doesn\'t mind spending on a complete car,I\'d get comp and champagne test before parting with cash,is there warranty on it

How the hell did you get hold of this what a toy

The cheaper one would do the job the other is just a bit more flash and I believe a newer design as long as it has a digital readout and uses a good sensor it will work I think they both use the Bosch 4.2

It wont use the o2 for start up so may not be that evident,mine was only bad because it ran so rich it was washing the housings down making it not want to start,

can any garage read the ECU codes? or do i need to visit a mazda specialist?
exhaust does seem to be blowing a little from towards the front of the car, but how much effect can this have?
ive just used the £40 i put in last week and got about 70miles which equates to 10mpg, and only maybe 3 time did i drive it hard, but only for about 1/2 a mile each time, i cant afford to run it at those costs!

Id fix this first mate,if it has a blow it will cause real flooding/fuelling issues as the ecu reads more o2 it throws more fuel into the engine thin king its running lean causing the symptoms youve experienced.
and it can lead you down the path replacing sensors/switches etc.
one of my own cars has a leaking second turbo and its horrifically rich to a point it it doesnt want to start on stock ecu

Exhaust leak is the first placed id look,especially if its running stock ecu and o2 sensor,they are very sensitive to air leaks.
also check map pipe hasnt broken or fallen off.
