Just bought an 88 Turbo 2 with 120 000 kms on it for 4000 and was wondering wat the cheapest and best performance mods i can do on it. I heard that adding a full exhaust system about 3 inch would up power and i would need a fuel cut off thing. Also wondering wat the diameter of the mass airflow sensor is .... looking for a filter to put on the end of it insstead of the stock airbox..thx

 

3 inch exhaust will up your power and give you a mean tone, try racing beat.com also the fuel cut-out, I've come across a few mostly on ebay. I believe a 3-inch cone filter will fit your maf, but rotaries run hot under the hood so unless your going with a full cold air setup I would stick with the factory airbox.
