This topic http://www.theminifo...opic=18618&st=0 Has turned to a turbo injection topic too

[stevenford_uk]

dude 100bhp is easy enough to get out of a near enough std metro turbo lump, as said get the 2 pin diff, and on the side of safety i would get some straight cut drop gears. run a little more boost than std with a decent intercooler and your laffin. still very drivable with gobs of torque, the initial spool up of the T3 is slower than the T2 but once moving through the gears its not noticable

MPi injector...





You can see the logo pretty clearly in the top picture...

Having experience with other Rovers of the same era (KV6 etc) I can tell you that logo is a SAGEM logo.



Watching the whole siamese injection debate with interest - as I'm planning to get back into the Mini fold after several years break (my last Mini was an '83 with an MPi conversion). Considering whether siamese injection, or simply doing the work for a BMW head would be easier!

Regards,

Brian.

Interesting reading - I even understood some of it

Going back to the start of the thread. don't Turbos lack low end grunt 'because their lacking oxygen, not fuel, before the turbo spins up?
If you're going to inject anything shouldn't it be nitrous, as well as fuel to match?

nah bud turbo motors suck the same as non-turbo motors do so 'off boost' they drive about the same its when the boost comes in that the magic happens, the reason tubo motors are poor off boost, low down is usualy because of the silly low compression ratio the engine has to enable far greater boost when the turbo comes in

EDIT:-

nitrous injection system's (nos) can be used to remove the waiting time for the turbo to kick in, an atls (or als) system using nos

just to add to this thread, my current project is being fuel intected using megasquirt (wet manifold setup with single large throttle body) and i am using the nitrous control on the ecu to inject nitrous off boost to irradicate all lag)

Hi All,

If you require any casting or machining,then I can help out here as we now have our own foundry........

[Turbo Nick]

any chance of an alloy block?

[Sprocket]

^^^ lol

[mini_turbo_pete]

you might lol at the alloy block but if you speak to Ian at Avonbar, he was (don't know if he still is or not ) haveing some alloy blocks made running 1600cc but still using all mini internals etc..

[Wil_h]

Didn't Ian sell Avonbar last year?

[mini_turbo_pete]

yeah he did but i believe he's still lurking about somewhere

[MRA]

Hi,

The last time I spoke with Ian, he was "on retainer" to help the other company get established etc.....

Alloy Blocks, not yet, not unless I get a lot of interest, however I am working on an uprated gear case and diff cover.....

However what I was also thinking was alloy "pattern" parts for the plenum pipe from Intercooler etc....

At the moment we are trying to keep things small and simple until our processes are proven and our quality is up to scratch, a bracket with a slight defect may not matter, a gearbox with a slight defect will leak like a standard one )

Also, how many of you would be interested in using a larger layshaft ? it would mean a slightly modified case....

Regards Martin

[Sutty01]

id buy anything uprated if the price was right mate , this new box sounds very interesting tho !
