The 4A-C exhaust system is a little weird, I have had a custom set of headers made for mine. Due to the fact that the exhaust ports are so close together, on my system the two sets of cylinders share the same pipe (so only two pipes come from the engine and mine are 2.5inch). The headers (I am not running a turbo) are a set of hurricane extractors that are ment for a transversally mounted 3/4A-C. Because I own a Tercel SR5 4WD (conventionally mounted) I got the exhaust shop to mod them (so they did not hit the steering) and run them a further few feet to underneath the car. All up the extractors and all mods to them cost $300, you could probably get a turbo one made for a bit more. I have however seen a set of extractors made up running 4 smaller pipes instead of 2 bigger ones. Maybe try searching on Google for 4A-C mods, you may find the sprinter with the mod. In regards to the carby, get rid of the aisin or what ever it is. I have mounted a 32/36 Holley down draft(same as a 180 webber) on the standard manifold. You could probably get away with the standard manifold if you port it a bit etc (I have not as my car is my transport, not that know one else uses them for that but I have not had time). I have seen it done on a little 1.4L nissan motor (standard setup carby engine turboed), a 32/36 carby on standard manifold with a box built ontop of it (half a shoe box size, maybe little smaller), which had the pipe from the turbo running into the side of the box. A cheap option would be a 34/34 webber off a carby XD-XF Ford Falcon, a mate brought one for around $30 the other month at a swap meet (put a $40 rebuild kit through it and you a laughing). If you have any problems getting an adapter plate to get the webber/holley to fit the standard manifold give me a yell as I know for a fact ( I have one) that Redline makes one. If you are feeling adventurous and don't want to muck around trying to get the standard manifold to flow better (inlet), custom build a new one and run a side draft like someone suggested. It will give you the best results in the long run, could be a bit of a job getting a custom built one to flow nice (see how good your fabricating skills are). I am not really sure what you should do first, because if you keep the standard inlet then you will probably have less room for the exhaust manifold. And if you build a custom inlet you would have more room to mount the turbo. But as I said see how good your fabricating skills are I hope some of this has been helpful, you can email me on jarredfoley@hotmail.com [Report message to a moderator]
