Hey guys,
My mate runs a turbo 1300 Sierra. First he started with a blowthrough setup whereby he used a weber, as you can pressurise the fuel bowl, and a t2 of an ET pulsar.
The thing wasn't fantastic but it worked, and went better than standard. This has led to the second incarnation in which he has used an EA throttle body injection, using the same weber adapter plate, a really old school microtech(dial style), and a new exhaust manifold. He has recently upgraded to a t25 off a Nissan CA18DET.
I haven't been for a run in it yet but apparently with the slightly larger turbo he says it's runs heaps better. A lot more power. Running 7psi through the standard motor seems fine, and the old setup had been running like this for the last 2-3 years. I realise with the extra volume of air it may be a little different, but we'll see how it goes. A very cost effective way of turboing your Sierra. The car isalso intercooled as well.
If you can get you hands on a cheap ECU, then the rest can be had for a fairly good price. Butif your not mechanicallyminded and don't do much of it yourself, then $1500-$2000 i recon isn't much to outlay for a decent kit done by someone.
Failing that I have a supercharged CA18DE in my Mazda 1000/Sierra and it shits all over my mates sierra. And availability of these motors are plentiful and cheap. We just put one in my mates sierra and the motor/box/ecu/loom was $300. Wiring $250, Fuel tank $50 and we did everything ourselves. Something to think about. But I guess I'm bias being a Datto enthusiast.
