forced induction Worth It To Turbo A M10

[Speedracer2002]

I know this has probably been asked and answered a dozen times, but just want to see the actual numbers made by M10 turbo motors.

 

I have seen plenty of M20 swapped and turbo e30s making great power and know its a step up from an M10. 

 

I'm wondering if a built M10 will make comparable power to an M20. I don't want to fully build an M10 to only make 250+ HP. I want to make a minimum of 320+HP I know a M20 is easily capable of this. Wondering if an M10 can make this power and hold it. 

 

I know it will have to have supporting mods to make this type of power, but want to see if it is worth it or just a waste of time to try and make this power out of an M10.

 

Thanks

It takes a great deal of work to get that power out of a modern design 4 cylinder let alone an M10.   With rods, pistons and a really good tune you should be able to get there but I'm sure it would be strung out.  If you have experience with custom turbo mods then you should be ok, if you are relying on somebody else to build it for you, expect it to be $$$.

 

That said, I think you should try,  I love to see those types of builds and these cars dont get them often.

Yea I have plenty of experience in the turbo field. I currently have a 380HP Ford Focus haha. I know M20 can make good power fairly stock, I just don't want to deal with all the swapping, cutting, and fitting of the M20. I kind of want to keep the 2002 to its "roots" with the M10 even though it will be far from its "roots" at the same time.

Yes.  It can.  Pistons, rods, o-rings and head studs and you're good.  There are a few things that take a bit of work,

but the 2002 cranks are MUCH stouter than the M20's.  And the blocks can certainly take it.

 

Do it.

How much money do you have?

Head gasket and head studs will be your limiting factor to get over 250 reliably ARP and MLS will be good for 350 reliably, maybe more. More than that and you'll need to consider pistons, rods, and grooving the block for O-rings.

Honestly though even 250hp will have you sh**ing bricks.

And at that kind of power, you'll need to think very seriously about big brakes, suspension, transmission, upgraded diff, and stub axles. Also a roll cage and harness is in order.

At just over 2200 pounds, a 250+hp 2002 is a very serious car, especially without computers to cut power when you overstep your boundaries.

Forum member Manimal has one that is already built. I believe it was making around 350hp before it was pulled.  I know he was considering selling it recently.  You could make him an offer....

I know M10 internals are tough, but the same can be said for m20's. Multiple builds on M20's pushing 6-700 hp on the stock bottom end under boost. A turbo M10 would be great, in the same respect as a turbo M20. The thing is, you may want to think how and when you want a power and to come on.

My findings with an M20 is that you max out n/a at 240ish crank hp, the main limiting factor being the 12 valve and restrictive head. You can probably squeeze out a bit more but you are looking into waaaaay more cash than you want to dole out. A blower or turbo on the other hand will cram more more air in than a naturally aspirated engine ever could so of course it's going to be making power much easier.

There are a few videos of mid 5-600 hp M10's in 02's, all turbo'd, and all with a ton of cash in the car and drivetrain. Once you meet the mid 200's at the crank the stock 02 diff will be on borrowed time, even beefed up, the next issue is half shafts. Solve that, than put on beefy suspension, bracing throughout the body, brakes, and than you might have a car capable of holding the power.

I guess you should tell us what you plan to use that power for, what your budget is, and if you are open to engine swaps.

I just plan on the car being a fun weekend car. I know its gonna cost money to make the car hold the power and put the power to the ground as well. I have a couple buddies with turbo m20 and m50 and both make over 400 but that's an extreme for me. I plan on making 400 but not having the car on that much boost all the time. If you guys are saying the stock internals of an M10 can handle 250-280ish wheel thats not bad at all. Ill probably build the motor just for the sake of it and having a strong motor. I know about lag, etc. I have a 380+HP Fail Wheel Drive Focus that has lag becuase of how big the turbo is. My plan is megasquirt, fuel injection, 45-55mm turbo, e85, header, exhuast, 5speed, lsd, and if i can make mid 250 with that ill probably just buy another M10 and build it right until this one pops.
