couple questions to GT4 people, jspec GT4 Options

[black13]

So I drove a 94 GT4 jdm model today and upon going into gear, it made a slight humming noise. What could this be? the owner had no clue and I was guessing maybe Fuel Pump? It turns off once car is in neutral for a bit.

Also what are some common problems with the GT4 that I should look out for? This specific car has about 160k on it. It's all stock.

And how easy is it to upgrade it to 300hp?

Yep, me geuss would be the charge cooler water pump bearings being noisey. The pump switches off after approx 30 seconds of the throttle being at idle and restarts once the throttle is actuated.

So would it be normal to make that sound or would it have to be replaced soon?

You only really hear the noise when the bearings inside the pump wear and become noisey, the bearings can be replaced seperately if you are good with a tool kit The bearings are available on ebay for a couple of quid.
