What can handle more horsepower the m113 5.4l engine or the m113k 5.4l engine I'm thinking of doing serious modifications to either or engines I know both have different compressions

 

If you have a '99 like mine, it is not very mod friendly, but because of the engine management, not the engine itself. Both mils are virtually the same except for compression and supercharging; the 55k makes more power out of the box and can have boost added to the existing supercharger, though, with just a pulley and tune. You'll really need to define what your specific goals are, though.

 

I have a 99 as well I wanna put a twin turbo kit on it and new cams crankshaft rods heads pistons transmission exhaust system headers I wanna know if the block can handle it which block can handle this amount of power what is the limit of 5.4 n/a or the 55k

 

Where should I go to get the end to work with what I wanna do with the car I wanna do this soon I have all the parts they all had to be custom made like every part, cuz they do not sell any of the parts I wanted. Where should I get a Ecu to make this all work I have 1000cc fuel injectors they are for the E55 55k will it fit on the n/a 55? I didn't think this threw when I brought all the parts that cost me a fortune I just wanna do this right and I have to find the right mechanics to do this. There are a couple in newyork that are really good but half of them only work on 2500hp hot rods and stuff in that nature I don't think it would be a good idea to take it to them. But I guess i have to keep looking for the right mechanics to do this right for me. I hope I find one soon

 

There is a user on here in the 211 section redbulljunky (I think) who has a twin turbo w211. He might be able to give you some more helpful information.

Yeah I know but if I had a w211 I would know what to do but the w210 is a whole different ball game. This car is made to its limits that's the problem the only thing u can play with is the engine but everything is made to it limits like the transmission imma have to throw it out and get the one they have for the w211 from weistec

 

Engine and transmission are virtually the same from the 210 to 211 E55. If you're going with a TT, radical engine build and custom engine management you can start with either one, really. The stock pistons would be better from the E55k but you'll need a intake manifold from a naturally aspirated M113 anyhow. The transmissions are built to hold the V12 engines and were also used in the McLaren SLR. They're rated to something like 700lb/ft of torque.

 

I was thinking about using that transmission but I might be going all out and push more then 700lb/ft of torque I need something at the 1000lb/ft of torque and the weistec transmission is the the way to go for now and the Pistons heads lifters cams and crankshaft are all going to be changed to handle more power
