R50/53 SRT-4 engine swap into MINI?
Wow... was that a shot??
Far be it for me, someone and possiably the ONLY one on this thread right now to have gone TC'd... Forget what mistakes have been made in the past... feel free to do your own thing and blow your *****... some people I guess just have to learn the hard way... There are plenty of threads that focus on TCing and turbo only so if you wanna pursue that, please, use the "search" option and be about your way...
Let's get back on topic shall we now???

Before this get's moved to OT... some of us are on this thread for a reason, not to be "content" with a n/a gas mileage mini....
First off, if I was doing it, I'd keep it a 1.6 to keep cost waaayyyy down. 2nd, building a turbo R50 based motor will not 12k. The R53 rods and crank and more than capable of the job so why upgrade? If this was me, I'd shoot for 300whp and be more than happy as that's far more than enough to shut down a lot of cars. New pistons, what 1k? Head, 2500. Turbo and manifold 3k. Cam, 400. Spend another 2-3k on fuel and misc. things like tune and I think you'll be good to go. On the other hand, I know I'm gonna catch flak for this as I can see what the attitude is of some people in this thread.

Flak caught...oh and its my attitude.
2nd, this motor doesn't even use the neon's ecu except for dash displays. The main differences is the throttle - mini is electronic, neon is cable.
3rd, The tranny issue is an unknown. Speculation suggests all that is needed is a custom bellhousing. Will have to figure that out when I put the two together.
Thanks Sush... I forgot about the trans and axles... make that $15k....

1st, you have to be willing to part with your car - you wont be getting it back.

Would you have to switch to a standalone ecu than because of the throttle? Cuz the drag car uses a drive-by-wire throttle body...
If you've got the time and the skills, than yea, for sure... but you'd prolly have to what like pull the housing and cut it, and re-weld a new housing to it so you can retain the trans cover still... cuz its not just unbolting the bell housing... that shell houses the gears of the trans and the diff too....
Genius! also instead of using an aluminum adapter plate or fabing a bell housing, couldn't we just use a wooden block with the bolt pattern from the neon engine on one side and the bolt pattern from the midlands on the other? If that doesn't hold, there is always epoxy!
Ummmm....as far as I know...NOT GOOD (I should know)...but it might work for Hemi to keep his cost down...
. And Ive been on this board for a very long time and what people still dont get through their heads is that it will cost you the SAME amount to build a Cooper as it is to build a MCS as far as the motor is concerned. Now, if you want to throw a turbo or upgrade the tranny...thats where the extra cost lies. And its really not that much.

Than why do you continue to try and build your post count by posting in "PERFORMANCE" threads???
If you have no desire to mod your MC and have done anything to offer any advice... what good is 3,000+ posts???
I'm not trying to get off topic here... or thrash on anyone... but DOOD!!! I'm actually trying to figure this out and hear from members who can offer assistance... isn't that the whole purpose of NAM... oh yea, forgot... we strayed from that a loooong time ago... now it's just a chat board.......
THATS WHAT THE OT THREAD IS FOR!!!!!
-Thank you drive thru

Thank you for the clarification El Jefe....
I have the most basic of bolt ons and in no way am I trying to build up a post count. And I hate to break it to ya, but this is the Coupe talk thread, not the Modification threads. That's down a little further. I post what I do and as much as I do when I feel I have something worth adding. Aren't we all here to ask for and trade advice? Tell ya what. Got a problem with my posts? Ask a mod to delete them. Or better yet. Want me to do it for you? Check my posts in the other threads. I feel like I never wasted a post (well, maybe a few
) but in now way do I go in and just throw up some random BS post to increase my post count. That's what OT is for.
) but in now way do I go in and just throw up some random BS post to increase my post count. That's what OT is for.Go ahead and ask... I'll throw it up here for everyone to see and we can take a quik vote... who here thinks arguing about an OT subject by someone who has NO EXPERIENCE in an MCS and barely their own car counts as a post again I will ask... please... read the title of the thread... pretty sure common sense will say this is a MOD...
I'm done arguing this with you.... if my post's need to be edited or deleted... so be it...
Hahaha that made my day
Thanks. I come for a Honda background, so I wouldnt mind seeing a K20 in the new mini's but I dont wanna start any fires yet.
There is power to be made with any motor, including the base mini motor. My biggest pet-peeve so far is finding a suitable LSD for the 5speed tranny, or if it would even be worth it. (Still new and have not done the research yet, so dont know the strength or compatibility of the mini trannies.) But thats a little off topic. 2.0l with SRT head monster sounds nice tho.

How funny
So, I read this saturday, then autocrossed sunday. And what was there, a 440HP, 400somethingish ftlb torque SRT-4...
I'm sure that would look much nicer in my car, than his, as after all, it's still a neon.

I know this is old and nobody cares anymore but Ill have a go
First of all a bit of neon engine history:
1.8 SOHC: Export neon shares block with 2.0. Possiable basis for mini engine
2.0 SOHC/DOHC: Mostly the same. Same exterior dimensions
2.4 DOHC: About 1" taller than 2.0 in terms of DOHCs the heads are the same
** Watch for NGC(next generation controler) it began on the PL(neon/PT) platform in 03 the engines use different cam/crank sensors. I am unsure of which is closer to a stock mini**
Mounting: On the drivers side the trans mount does everything. There are 2 mounts on the passanger side an upper and a lower the lower is refered to as the "torque arm" its primary funciton is to reduce engine movement. The upper mount holds the engine in the car. I will get pics asap.
Trans: SRT uses NVG T-850 its a truck trans, it works like one and is probably the biggest reason I dont have an SRT. The NVG T-350 is more than strong enough(if you can live with 600wtq or less) and shifts pretty well. I will get a pic of the bellhousing asap. If the gretag will fit use it.
Wiring: I have no idea, get a megasquirt box and play around a bit
E-Throttle: Drill a hole in the fire wall. Use neon pedal set(1gn is better set to heal and toe downshifts) use V6 Caravan throttle cable, you'll be able to wrap it around the engine before you connect it to the TB, length will not be an issue

I think you mean a 1.6L instead of 1.8L
And the 2.4 and 2.0 heads are different with an exception. The early non-turbo 2.4s and 2.0 use the same head. the later 2.4 (as in the srt) uses a different head - oil feed is in a different location; but can be modified to work with earlier blocks. The srt head also has a different port and the exhaust valve is 1mm smaller but is inconel.
I don't know if you are refering to the MINI's mounts or the Neon's. The Neon has three; tranny on drivers side and upper on passenger, then one in the front middle on the bottom. There may be a bracket on the later neons in the back for a mount (I removed something from the back of the block in my 1gen DOHC to 2gen SOHC neon swap) but the motor wasn't attached to a car when I got it to know what it was.
A concern not previously addessed is the power steering. Putting a 2.4 in a neon requires a different mount to be fabricated for the PS - its actually common not to run PS cause no one wants to deal with it (actually one of the reasons I went with a SOHC rather than 2.4 in the swap mentioned above). Brackets can be found with some searching and monatary persuasion on neons.org. In the MINI, the pump is electric and behind the motor which could cause some problems with PS rerouting not to mention steering the rocket ship in general.





Ford guys do it when they use a FWD engine and adapt it to a rear drive trans.
