Turbo Mpi?
Turbo Mini Forums

ok guys after quiet a bit of research and numerous attempts with and inlet manifold i have decided that i am going to chuck a T2 onto my 2000 Mpi cooper. My install is going to have to be and over the weekend job as the mini is the only car i have, so i want to make sure i have all the bits needed to do the job. Here is my list if anyone can see anything i have missed or has any suggestions then that would be great.

1.inlet manifold
2.exhaust manifold
3.turbo
4.intercooler
6.X-pin diff
7.central oil pick up
8.pistons
9.oil cooler
10.lathe shaft
11.turbo oil pump
12. fuel pressure regulator
13.ECU
14.alloy throttle body
15.silicon hose and clamps

what you guys reckon?

I reckon that you must have a good idea on how to fuel it?

Surley you will need to map it properly on a rolling road which can take hours and hours to get just right. I think you may be being a little optomistic to get it all done in a weekend.

I'm guessing you are going to run it on a carb? If that is the case I think it is possible but a weekend is absolutely unrealistic.

Nope running it on the injector system, through the intercooler into the throttle body with the plenum. the injectors are going to be mounted on the runners

Good luck fuelling it properly then, as no one else has managed it yet.

Hi,
I'm doing mine throttle body injection, in my eyes that's the only quick and relatively easy solution.
Take a look at

are you using the standard ecu?

For my 2p's worth...
I joined this forum about 6-8 months ago to learn.
And from what I've learnt, turbocharging the Leyland/Rover SPi or MPi is not a simple, viable option.
I've still got a lot more to learn and am going down the Megasquirt route (albeit slowly) but there is so much more you ought to read in the A-series injection section of this forum first.
You will not put fuel injection and turbo onto an A-series in a weekend !!!
Well, not in my opinion...

Schrödinger's cat - so which one am I ???

Hi,
Andy .. No, none of the Rover Ecus fitted to Minis can work with boost.
I'm using a VEMS ECU.
Retired .. I think I could have if I'd had all the parts ready to go and used a T2 or T3, thanks to the help from the VEMS forum and Sprocket.
I turned the key and it did run first time!
EDIT:
V700 .. If your pulling the engine and the box apart you've got absolutely no chance! That's more than weekends worth on it's own!
Cheers,
Gavin :)

Hi,
No disagreement here Rod!
Not with limited research, you and I both know it won't happen!
I'm an auto electrician and mechanic by trade, trained in engine management.
I still needed to do a years worth of research on TM before choosing the route I took, which is still largely untested at this time.
Cheers,
Gavin :)

1/4mile in 13.2sec @ 111 terminal on 15psi

Certainly very intrested in how well this all goes so keep us informed of progress. Good luck.

I have been planning for a year now and i have done so many different calculations and designs, with the help of my mechanical drafting teacher we have produced a final inlet manifold design based on the sums we did. i was just wandering if any of you guys that have built turbo motors had any little things you wish you had or any parts you found worked really well, i am just checking i have not missed anything before i rip the motor out.
I think i mislead you guys by saying having it all rapped up in a weekend i plan to do the ecu and wiring the weekend before so i am going to take friday and monday off work and then pull the motor out friday morning and get that going, hopefully be slotting it back in by sat evening leaving sunday to do the checks and get it running. Monday i was planning on spending the day at the rr getting all the maps sorted and it running sweet as a nut!

GOOD LUCK (and I mean it, no sarcasm intended)

In the 13's at last!.. Just

How about a dose of realism?

If you plan on changing pistons, diff, layshaft and oil pickup, then no chance.

The standard MPi ECU will not fuel above 90hp or so and there currently is no aftermarket or DIY ECU that is fully proven to work with port injection. So unless you know something we don't ?????

I've been building an EFi Turbo 998 for two years now and it is still not running.

Saul Bellow - "A great deal of intelligence can be invested in ignorance when the need for illusion is deep."
Stephen Hawking - "The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge."

Do you fully understand the difference in the practicality of injecting an engine with two cylinders sharing the same inlet port as opposed to an engine with equal numbers of inlet ports and cylinders?

Building the engine mechanically is the easy part, there are any number of people on this forum who have done so themselves. Fuelling that engine with a 5 port head and injection is not easy and despite some very intelligent people trying, no one has got there yet, although some are getting close with a specifically modified ECU code to cater for the siamese ports.

Maybe you will be the first to achieve this, but unless you understand why it is not a case of fit a mappable ECU and off you go, I really do doubt it.

Before you embark on this type of project, you need a basic strategy that is workable.

Your basic building blocks need to be identified and they need to be proven.

No one has answered your original question because we feel that the fundementals are flawed.

If I were you, I would get another engine and box and get it rebuilt to your specification, get it in the car and running on the MPi injection. Once you have sorted an ECU that will work at high power, then fit that. Finally attempt to Turbocharge it.

Friendly advice (seriously) you need to understand the issues associated with port injection on a siamesed port engine.

The A-series is NOT simple when it come to fuel/air flows down the siamesed ports.

There's a link here (it's all over this site but to save you searching) that should explain it.

http://www.starchak.ca/efi/siamese.htm

But, if you think you have a simple way around this basic problem, let us know.

Good luck BTW, I only started 6-8 months ago as a little "project" (obviously I'm not in a hurry for the reasons you say in your first post) but I won't be finished for a long while.

Sorry,

I should add - don't let some of the negativity above put you off.

If you are going to try it, please share your experiences, positive and negative, to help us all.

Schrödinger's cat - so which one am I ???

Maybe it is just me and what i have been involved with, but i think the situation is getting over compicated. There are two inlet ports on a a series engine each feed 2 cylinders with the fuel and air, be it a carb or and injection system the fuel and air mix still goes in through those two ports, if anything a injection system is going to work better with the turbo because each inlet runner has one injector that way the fuel can be controlled through the boost and rev range. Again maybe i am slightly unaware if how hard this seems to be but if you take the basics there is only two inlets for the fuel and the air and if it is mixed then it does not matter if you running a carb or injection the fuel air is still going into those two holes and being split into the two cylinders,
Thanks for the comments guys they are raising really good points :)
