Let me see some pics of the engine.


Do you know if he did the Turbo II swap correctly?

Why do you need more fuel? Some basic things are a Walbro 255 fuel pump and regulator. But the rest of the stock stuff it good for 300hp.

You will need an FCD to run more boost. The car will go into cutoff mode and jerk and pop and crackle. An FCD (fuel cut defender) will stop that.

Thanx for the response.I've got the car stored at a buddys for the winter but I'll try to slip up there before the weekend to get some pics.I'm not sure what you mean by 'was the swap done corectly'?(not sure what to check...ecm,fuel pump,ect...)And you say the stock fuel set up will be ok to run more boost as long as I use a fcd?Thanx again Chad

Ok. Let me see some pics and we will just go from there.


A stock ECU is not meant to run any more boost that stock. If you put a boost controller on then you will hit fuel cut... which is a pain in the *** and is very aggresive jerking. An FCD will stop fuel cut but is dangerous with too much boost because it will not go into fuel cut.


Well basically i mean who did the swap? A custom garage or the guy in his backyard.

Hey Man,I have no way of finding out who did the swap,but to the best I can figure it was done in a shop.The car runs really strong,and pushes no oil at all,I bought it for $700 to race it locally at a strip,but once I beat a few V8's I figure I'll soak some money into it.How much boost is safe to run with a stock ecu?I don't want to hurt it at all,but i do realize that I need a fcd,(but wich one is best?or they all the same?Thanx again Chad

Just for the record... V8's SUCK DICK!

Well it is hard to tell who did the swap.

Do you know what engine it is? Is it a real 13bt or just a 13b turbo swap.

Why was the car so cheap?

With the stock S4 turbo I would run 11psi max! Anything more than that and you will start to fry your turbo. With an aftermarket turbo... 15 on stock motor and fuel system. (It will overheat easily with stock radiator)


Pretty much all FCD's are the same. I know of people that make them. But you can buy them for cheap from HKS.
