Turbo Inlet Duct

This is the heavy rubber / plastic ducting from the air flow meter. They are getting brittle from age and heat, then cracking. The car idles rough, and is down on power and boost.

Stock Turbos, Manifold, and J-Spec Upgrade
The original equipment turbos and manifolds are extremely prone to cracking due to the incredible heat generated by the engine. We have continued looking for a "rebuild" place that could maintain a consistent supply of buildable core turbos, but we have never found one. Assuming your turbo is not a usable core, and the manifold is cracked enough to not be usable, about your only choice is buy a new one which is not inexpensive. The '99 J-Spec Turbo is a nice upgrade from stock for the 93-95 Twins, and the price is significantly lower than the US version.

(The 99 spec compressors received special abradable housings to improve impeller blade clearances and turbine housings were made “roomier”. This creates a faster responding turbo, better efficiency and higher boost capability for more power. These turbos are capable of seeing 330-350hp)

93-95 Turbo Charge Control Valve
This controls the amount of airflow going between the two turbos. If this breaks, the wastegate won't open and the air flows back into the filter. This causes the turbos to try and pressurize the atmosphere.
