i am needing to find some 550cc injectors for not to much, and adjustable wastegate. do you know where i can find a not to expensive wastegate, and injectors. and if anyone has any and are looking to sell them how much do you want for them. also i am trying to decide between the Z32 or cobra MAFS, which would be better?? thanks

well, I don't know much about ford mafs so I went with the Z32. besides it has extra capability if I ever need it. the cobra ones, if you take a core in to advance auto, you can get a rebuilt one for 90 bucks, and it would be nice to have a new one that you knew had no problems with it. The z32 are like 500... for me the Z32 were easier to find.The cobra you need a JWT ecu to tune.If you are tuning with like an safc or emanage, I have an RB20det mafs I could sell you, I thought it was a Z32.as for injectors I'd get some delphi top feeds off ebay and that JWT fuel rail in the for sale section. or a mustang fuel rail.wastegate, stone mountain racing makes ****ty manifold but their wastegates look OK, and they are cheap. or you could bid on a tial and you might get lucky.

fitment was good, I made some brackets. anything that fits the mustang would fit that. or delphi or msd , etc.

Here is a link to my page with the pictures:

for wastegates I highly recommend tial 38mm. I works really well. go to http://www.fast-turbo.com/ to get the tial from. I got mine for 203 bucks. I have used the stone racing one and it is just a POS, it is not worth it spending money on crap because it will be cheaper in the long run just getting the good stuff in the beginning.

if you want injectors--go to http://www.racetronix.com and scrol down till you see the selection of injectors--the cheapest anywhere so far... 243.00 shipped.

If you go with a cobra maf--keep in mind that the car willnot be able to amke over 350-ish wheel horsepower unless you go with a jwt ecu and bigger injectors. Themaf maxes out at that power level. The z32 is easier to tune with an AFC. The cobra is said to have better resolution and give more accurate readings to the ecu. cobra uses silicone couplers on the inlets and outlet. The z32 use a coupler on the outlet, and a bracket on the inlet. Keep that in mind when install time comes too.Are you going blow through- or standard.
