I just last night finally got my 88 T2 off the jack stands and out for the first drive since last December. The Rtek 1.8, Walbro 255, four RC Eng. 750cc inj. S5/BNR stage 2 hybrid turbo. Everything seems to be just fine, wideband says A:F under WOT right at 11.5.
Very Happy with the Rtek.

 

Sounds good! How much boost are you running on that turbo?

 

Due to lack of time I really haven't had time to do more then warm it up and get around the block a couple of times. Right now I have the wastegate actuator plumbed straight to the turbo outlet without the restrictor pill. Boost comes up to stock level pretty nice like this. I just picked up a Blitz EBC from a forum member.
Once that gets in (time thing again) I`ll crank up to 10psi and see what I've gotten myself into.

 

Sorry, double post.
