Injectors where from
Turbo Mini Forums

Looking for Bosch injectors around 200cc (roughly 160bhp equivelant at 80% duty), any ideas from which cars I can get these?? saving me time narrowing it down

Thanks

MS

OOH found these on ebay, what do you recon??

You can't go wrong with the injectors used in the earlier Rover 16v turbo motors - before they switched to the dizzyless & sequential control.


These are available for 10-a-penny. Well - not quite, but very easy to acquire from the Rover Turbo Forums....

well thats brought my faffing with MS a lot closer, good info!

homemade TB here we come....

I've seen the future and tbh its Pie

if its any interest minisprocket i use bosch 749's in my 16v conversions found in any pre 1994 calibra.

Ask yourself? why do most championship winning minis use morspeed?

Thanks for that, but looking at the 749 I get it to 120bhp at %80

Im sort of lost now minisprocket to how you have worked that out,

749's give 215-220bhp @ 80%

The std calibra has 150bhp and is tuned to 220-230bhp still running on the 749's.

QED use 6 bosh749's in there rover KV6 engines which give well over 300bhp.

At what pressure you working on?

if your looking at a 200cc injector then the bosh 734 is bang on 200ccpm-19.3lb per hour @ 2.5 bar. this will give over220bhp.

i use the bosch 749 which is 249ccpm-31.0lb per hour @ 3.0bar.

Well i have just looked at two different documents that state two different figures for the 749s the first shows 170cc/min at 100% duty and the other shows 218cc/min but does not state Duty

Now the first figure is almost exactly 80% of the second but that may be coincidence. I however suspect that the coincidence is correct as the 682 shows 511cc/min and equates to 87 BHP at 85% and the Cooper Garages SPI pack ( Cooper Garages stretching the duty %5 to achieve those power figures)

So my first statement on the 749s may well be wrong as you kindly pointed out

Which is it to be and where can I get accurate information?

Edited by Sprocket on 11th Apr, 2006.

all my information came from the guy who makes modified injection systems for me.

He has the bosh catalogue with all the information i gave above, we have had no problems with the 749's in any of my 4 'K' 16v conversions and he assures me its perfect for the job.
If thats what you intend them for?

Loving the pictures in the signature, looks good!

The pictures are fab. I am supprised how low the head is in the engine bay. Looking at it on the bench I would have thought it would look much higher.

it's only 10mm taller than the standard head with minispares rocker cover

its actualy a very sweet looking conversion and looks really retro to me,
It took me ages to figure out how to post pics but i had to persevere with it as some form of proof for others.
Instead of the unortherised pics people take of random shit lying around my workshop without asking

who would do such a thing!

bastards...

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

Take it that's you Joe?

Loads of people do it, i dont mind really just seems to be either the scrap or half started units that they like to photograph?

i had a company from abroad come and visit, then a few weeks later they send me one of there catalouges and i was horrified to see they had took pics (without me knowing) of heads from other companys in my workshop that i use for showing poor workmanship offering them as morspeed heads!!

Hi, I have searched around for these injectors, and after a bit of investigation at the E-cat on the bosch homepage, I find the pre 94 calibras used bosch 0 280 150 427 or bosch 0 280 150 744.

data on 427: 241 cc/min, .47 BSFC 80% 39.1 hp.

data on 744: 214.4 cc/min .47 BSCF 80% 34.7 hp

and there is two types of the 749 injector. the 0-280-150-749, that is used on Rovers and volvoes.

data for 0-280-150-749: 218.1 cc/min .47 BSCF 80% 35.3 hp

the other type is 0-280-155-749 found on saab turboes.

data: 350 cc/min .47 BSCF 80% 56.7 hp.

Just to clarify all of these are high impedance units.

I dont know which one of these you are using Simon? but there doesnt seem to be 749 injectors used on the calibras,C20XE engine (pre 94)?

I am after some for a NA K1100 project. maybe with reground cams, if not with RS cams, looking for between 135-165 hp, which one should I use?

or maybe this would be good?

0-280-150-432 240.2 cc/min .47 BSCF 80% 38.9 hp.

also found on saabs.

Injector choice sorted, just need to find some. Seems that there may be a few others searching the same sources

dont forget the cossie yellows very cheap and easy to find

what have you choosen minisprocket? what do you think about those I have written about?

The only injector to use is the one every one is talking about

and that is? the MPI injector? isnt that a bit large for our use?

Depends what you mean?

Im running 1275, 16v and a turbo.

response times proven to be good for short sharp bursts of fuel with good controlability at low duty cycles which means good idle
