Oil/Black residue out the exhaust :s

I have recently purchased a R33 series 2 gts-t. It has 150,000 kilometers on the odometer with 67,000 on the the gear box (has been converted to manual form previous owner). It has a few small issues ( as every car has) and was wandering if you guys could help clear some things up...

First- Oil and black residue shoots from the exhaust, not much smoke but its still concerning...
Second- Everything works in the dash except for the actual tacho that reads the speed im travelling, I have chased up a speedo sensor ($200) but was wandering if it was something silly first.
Third - how often should i service it and is there anything else needed to be done except the bog standard; filters, fluids and brake pads...
fourth - Any random tips or advice would be much appreciated

Does the black residue out the exhaust only happen when its cold? Mine does this, think its just moisture in the exhaust coming out, bringing soot from the exhaust with it, so black spots on the garage floor

Speedo sensor goes from the gearbox to the dash then to the ECU, so either something is unplugged (there are some plugs at the gearbox then I think they run through a plug next to the relay box in the engine bay). If everything is plugged in, maybe pull the speedo gear out and have a look. Its been converted so maybe the previous owner missed something or did something a bit dodgy

Might be, it seems to be a common thing [emoji28] that and it's also been sitting for 3 months... guess I'll drive it steady for a month or so than take it in for full major service...

As for the speedo I checked and they did put correct speedo sender in but forgot to connect it properly... loose behind dash cluster. Was annoying to find but I had fun learning around my new pride and joy

Servicing....depends, if its standard and just going to be a daily driver, every 10K, if its boosted and/or your pride and joy every 5K.

 

When was the timing belt last done??? Could be way overdue???

 

Lastly tips.....you found here so read, read, read and search, search, search.

 

Also have a look at the Forced Induction Dyno Results section, plans start from there!!!
