Basically I am trying to built a quick NA engine for my MC, and I am looking at the stronger MCS engine as a starting point.

So far I have figured that I will need a custom ecu tone and I may be able to get away with using a schrick cam from a MC. Also I am looking to swap in forged MC pistons to raise the compression.

I know that for the price it would really obvioulsy be cheaper to just trade my car for a MCS and build the same kind of car everyone else has, but I not doing that so please refrain from telling me to trade for a S, thank you.

 

If you wanna refrain from going "S" then add a turbo kit. By the time you build the block, head and all possible bolt-ons you will spend a boat load of money and probably feel cheated for the small amount of power you'll add.

My vote for you would be turbo. You''ll spend less and in the end have a lot more power than trying to build up an NA car that doesn't even have 150hp from the box.

LAST kid who went turbo in our club got home on three pistons from the shop.

these motors are not designed for that type of set up, i would suggest a full built engine.

 

+1. You will need forged connecting rods, and probably an upgraded crankshaft for starters. There are so many differences between the two engines, that if your desire is to keep the MC body style, you really need to financially prepare yourself for a replacement engine. Trying to do it on the cheap is likely going to result in less than an optimal outcome (such as the 3 piston scenario that elprofe mentions).

 

Swap in an MCS engine and go turbo only.. that way you could keep the Cooper hood which is much nicer than the S hood... it'll prolly be cheaper than building up your current engine, just too many things to change...

EDIT: When going turbo only you would obviously go with a FMIC and re-route the charge pipes in a manner to allow the low clearance of the Cooper hood...

 

he is starting with the s block. he will not need a stronger crank shaft. that crankshaft has survived about 600whp. The crankshaft is fine.

THe rods are probably fine too! rods have gone over 400whp... and you will not be pushin anywhere near there. ALso, NA is a little easier on things than FI. I doubt you will need new rods... It would be beneficial to put some new lighter weight ones in... but you won't need new rods due to strength.

By the way... if you are building the motor... and puting high compression pistons in it... it would be a waste not put a little nitrous on there... nitrous LOVES high compression!

 

That is true.... I forgot that the objective was to go to a NA from an S.... Why someone would want to do that (go from an S to a N/A) is still beyond me.... Kind of like trading in a bicycle for walking shoes....

 

differnt strokes for differnt folks...

my hats off to him for doing something differnt... don't forget to mount the water pump... i would say go with the electric one...

 

Wow we were talking about the same thing today, we hope to have a motor built before xmas.

 

The thought has crossed my mind, I figure I will get the motor going first but Im sure a nice shot wouldnt be to far behind

 

Thanks a bunch, I like being different rather than the high HP race, but I still have all the respect in the world for those guys, paving the way, and giving the Mini some cred

 

One question that is always in my mind is how much HP I will be able to make. Im not sure how much power people have made form other 1.6L NA engines not nessecarily the mini. I would like between 180-200hp, Im looking to be able to bet a stock MCS, on a track of coarse

 

I'm not sure of cost differences, but wouldn't it be more money to swap the engine than to switch out internals from the MC engine? Since you have to replace the pistons in the MCS engine, wouldn't it make more sense to switch out the internals from your existing engine. Once you have the head off, the crank is easy. With the head off, replace it with a p&p mcs head, put in the forged pistons, crank, and rods. You are going to have to take the engine apart no matter what engine you use. It also seems like more work to swap out an engine, and take the new one apart to put in pistons, when you could just swap out parts from the existing one.

Either way, some nitrous is in order...

 

Yeah that does make sense but I can't really afford to have my car in the garage for a while, thats why I like the idea of having a second engine that I can build while having my car functional.

 

Well, my guess is that you will probably make about 160 ish to the tire... the most i could see you making with stock displacement is about 180 to the tire. If you bumped it up to a 2 liter... 200 to the tire would be possible. these are going to be very difficult numbers to acheive with what is currently offered. YOU will definetly have to be innovative. hunt down new cam specs have custom pistons made (not difficult at all its quite easy) and then engine managment will be the issue. but I think it will be totally worth it in the end. Also, don't forget the nitrous!

 

I could deal with 180hp, than I may go with straight cut gears, yeah I may have to stay out of the fast lane but whatever.

 

Im looking for more of a extremely free revving, responsive engine.

One thing that has been brought to my attention is that the ratio's of the 6-speed may not match very well to lower HP numbers so I am hoping to get the HP number up to that of a MCS, maybe a little more.

 

I like this idea becasue I could have it running NA for a while and if I wanted to I have the ability to pop on a turbo if I want more power

 

uh... why not.. um.... get an S...? Just playin' i think it'd be bad *** to whoop up on us with the S's with an NA cooper (well maybe not us S's, but somebody). But that's money too bro and there aren't too many people with the same idea so you're going to be dolo solo when it comes to advice on the best way to do it. Keep it it gangsta and build that ride though, you'll get mad props and all the be-otches too, playa playa!!!
