Recommended Posts

Finally got round to finishing this project on my 94' UK spec auto...

 

Stock manifold has been modified to accept a 38mm Tial wastegate ,which vents to atmo :)).

 

These are stock based hybrids with the following work..

No.1 turbo the wastegate has been plugged and machining work done to housing...

No.2 turbo the exhaust bypass valve has been removed and again machining done to the turbo housing..

These are running in TTC mode....so all vsv's and associated pipework has been removed...

 

Have now had a boost controller fitted and upped the boost to 1.2bar ,plus had a MAP ECU fitted to remove the stock MAF ..

 

Had the car on the dyno ( Thor racing )

Results of the latest dyno.....407bhp and 397ft/Lb at 1.24 bar

 

Holds boost rock steady and its worth it just for the extremely loud wastegate :))

 

There are some pics and dyno sheet at http://www.dazzspeed.co.uk under turboproject..
