brilliant conversion, tho i have to admit i dont like the servo mount point, have you considered ditching it for unasisted setup? i m going to do this conversion soon, i had a micra before a mini and loved the engine, do you reckon you could fit a front mounted mpi radiator to this conversion?

well......... what's not to like about the servo mount point? it's completely out of the way of any thing [kinda tucked in the corner] and allows engine removal without even touching it! as far as the rad is concerned, we live in the tropics of the caribbean and i've found that the mini 3-core rad overcools in its original position, just going above normal when thrashed but cools right back down. mounting the mpi rad competes with the exhaust mani for space but i'm sure it can be done.

that engine looks like it grew there ! congratulations on such a "clean" looking conversion, i'm sure this is a great engine for a mini , all the reliability of a modern nissan, an easy 75 bhp plus as standard (probably a good bit more with the air filter and exhaust) and a five speed box as well............ i quite fancy having a go at this myself, imagine how much it would cost to get this sort of spec going the traditional A series route, you would need at least a john cooper "S spec" MPI conversion(rated at 90 plus bhp, but seldom seem to make much more than 80 in rolling road shootouts) plus an unreliable and very expensive five speed box, you would probably have to spend upwards of £4000 on your late model mpi cooper ........ i'm sure a lot of people on here are saying its a LOT of work to go to for such a small increase in power over an A series, but in my opinion 80 to 100bhp in a mini goes a LONG way, especialy with a five speed box to help row it along , and its a small light engine which is VERY important, as a lot of people have ruined the drivability of their mini by putting too heavy an engine. well done mate ! keep the pictures (and videos) coming ,i cant get enough

its a good way of putting a servo in, i like the one on the 13th the best, im just not a fan of servos and prefured it without becuase i thought it looked alot neater, i see the pictures before you have the standard non servo assisted vertical mount master cylinder, which is what i would like with a set of 4 pots.

im really trhinking of doing this conversion, but there are things which worry me like whether a front mounted rad will fit and how far offset the driveshafts will be from the middle, it looks like they are going to be very close to the passengers side, does this cause a problem with torque steer? is it possible to get an engnine in with the cvs in the middle?

i dont want to sound negative, its awesome, definately my favorite engnine converison, i wanted the engnine out of my old micra in my car years ago but i didnt think it was possible, great work!

Torque steer has nothing to do with driveshaft length, it is the bending force the torque applies on the suspension geometry. I imagine 99% of FWD cars have unequal length drive-shafts. You're worrying for nothing.

are you sure u've got nats? if so that's ALOT of extra trouble for no reason since no-nats wiring is very simple on the cg series of nissan engines. using the transponder ring etc is just another thing to go wrong on a motorway IMO. try to find out if u've got nats.

yes it has got nats, i have a mate who is an auto electrician to help me and hope he can sort problem out
( just a quick question) as i have the complete car do you think it is possible to put the power steering rack
on the mini and convert it ANY ONE TRYED THIS.?
and what about the complete dash(with some trimming of course)
andy

[Artstu]

The power-steering pump on the back of the engine would fowl the tower, and the rack is very bulky.

Dash would be a bit bulky too, however you really need the pod to match the electronic speedo, although it will read a bit fast on smaller wheels needed for a mini.

thanks buddy i will bear that in mind , i still may have a look when i do my engine
job i will let you all know what happens

has anyone tried taking the mesh out, from over the throttle body on the k11 micra manifold?
and yes torque steer doesnt seem to be to do entirely with drive shat length, its odd that theres an equal lenght drive shaft conversion "to reduce torque steer" for the mini.

oh and how is the cluch operated on these conversions? i dont see a master so it must be cable?

As a side note, have a look What Causes Torque Steer Thread on TMF. While I personally don't agree that this is the sole cause of torque steer, it does go a long way to explain what contributes to it ... and if this article is correct, then why does the torque steer always happen in one direction (left or right) no matter what road surface/level you are on or what tyres are fitted. I guess that's a debate for another thread...

the mesh comes off easily, i used a sharp pointy knife to coax the circlip out and the mesh just pops right out. theres alot of confusion regarding torque steer but in my experience wheel offset increases the risk of it getting all wild when power is applied. anyone whose gone from 13x7's to steelies in front would know exactly the huge difference offset makes! oh by the way all of the clutches shown in this thread are cable operated, initially we used a 'pull from behind pedal' approach but later moved on to 'pull upward from under pedal' which hides neatly beneath floor upholstery and the cable exits just above the steering rack. u would not believe how SOFT this clutch is!!!! u can easily drive around clutching with your toes only.

Hey Bigchief any chance of a pic of the mods to the left side of the subby?
and maybe one of how close the left inner cv is to the subby?

[flying banana]

a quick up date took micra engine out today it does look big !
and hears a couple of pics



and this is my lovely mini its old but its cooper cool
998 mk2 cooper and it has a flip front so as to aide my transplant

andy

[Artstu]

That's a nice clean engine, some people rev those 998 engines to 9000 rpm without too much trouble.

[bigchief3679]

wow, that engine sure is different! its got coilpacks, crank angle sensor on bell housing, knock sensor, different throttlebody, top feed injectors. jap-spec blacktop CG's are alot simpler but glad 2 c u started! good going
