questions about 1994 idi factory turbo

i have a couple questions about my truck
1. my oil pressure is on the low side no matter what it never moves up or down just stays right at the first bar on the guage it can be idleing or on the rev limiter the oil pressure will never move what could that be?

2.how fast should this truck be i have had it for about 2 months but i have been driving my dads 07 dodge because my truck has no get up and go.

The stock factory gauges suck big time, they are more idiot lights at the best. They actually dont measure crap. For example the oil pressure gauge comes on when you got past 8psi of oil pressure, and there is a little resistance do-hicky in there somewhere so that it looks like it is changing positions. Buy some mechanical gauges if you really want to know whats going on.

Sorry I had to. IDI's are slow, you cant compare an 07 dodge to an IDI, it will walk away from it at half throttle. Look at the factory rated power, it aint much, I forget what the factory turbo motors are rated at, but stock they aint even rated at 190hp I dont think.

If you wanna make it run better, here is what you have to do. First get yourself a set of GOOD gauges, no cheapo find them off the shelf at Autozone stuff, I'm talking ISSPRO, Autometer, name brand stuff. Get yourself a boost (0-15psi) and pyro (with the thermocoupler and wiring). Now install both gauges, put the thermocoupler in the drivers side exhaust manifold for the most accurate reading. Now, since those are in, get yourself a bigger exhaust. The exhausts for OBS PSD (94-97 Ford powerstrokes) will fit, might need some modification because the downpipe might exit in a different location. I would go for a 4" exhaust. You can fab up your own exhaust, thats what I did, and it cost me like $120. Now you can buy an upgraded turbo housing and downpipe from ATS, but its like $800. So if you dont want to do that, cause I hear they are having quality issue's this is what you should do. Take off the stock downpipe and cut it off towards the flange, then weld on a 3" exhaust pipe bent like the stock downpipe is, you might have to clearance the firewall to make it fit. Dont run a muffler, you dont need it. Now turn up the pump. This will get you some good power, like along the lines of a Stock OBS PSD. Dont expect a rocket ship.

i dont expect a rocketship at all and i know that they arent fast but my little moped will seriously accelerate faster than this thing will lol and that thing is only 40cc i have been planning on putting an exhaust on it but with diesel prices all of my money is going into keeping this thing fueled up but i guess thats why i need an actual job instead of just doing odd jobs for people lol i have been told to turn up the pump and adjust the timing but i dont know how can somebody give me some instructions on this
