150-160 BHP FROM TWIN CAM

[sal]

hI ME AGAIN

TURBO IS A OPTION BUT SOUNDS COMPLICATED AND EXPENSIVE SO WHAT IF
I WANTED TO GET THE ABOVE BHP, WHAT MODS WOULD I HAVE TO DO TO THE STANDARD ENGINE I DON'T WANT TO USE 40'S
I WANT TO GO WITH INECTION ,ECU, ETC.

IS 150 -160 OBTAINABLE FROM THE STANDARD UNIT, THAT SORT OF BHP IN SUCH A SMALL CAR WOULD GIVE SOME GOOD PERFORMANCE FIGURES, WOULD IT NOT?

Hello Sal,
Is the Montecarlo really the car for you ? In reality they are underpowered and under-braked so to get the sort of car your are obviously looking for you will need to do a lot of modifications. There are lots of mid-engined cars that can instantly offer the performance that you want, indeed there are lots of front engined, deisel powered cars that can offer much more than Montecarlo power. I just got burned off by a VW Passat !

Apologies for being the Devil's Advocate, but I enjoy my Montecarlo for what it is, although I do curse the motorway cruising harshness.

Personally, I would start with the Beta 2L unit (costs just a little more than buying the FI components alone), add one of any number of aftermarket programmable ECU's, swap pistons to ~10.4:1, invest in a port and big valves, and swap cams (or a 40/80 intake minimum) Now, you are comfortably in the 150-160HP range, although your wallet's approx $3K -$5K USD lighter, depending on how much of the work you do yourself.

There are other cheaper alternatives, yes. It also takes a lot of time and patience. But starting with another motor cuts your risk of ending up with a half-finished car that's not saleable. Once you get the 2L built, you can swap in in without a great deal of ado, and proceed to tune the FI.

You will need (or pay someone to do it for you)
Basic mechanical skills
Understanding of the TC motor (several books on this)
Basic electrical skills (for FI)
Basic programming skills (for FI)
Basic welding skills
Ability to problem-solve as minor issues develop

And a lot of support from folks like you'll find here is a plus!
A lot of us have already been through the process, sourced the parts, and fabricated other ones as necessary for this conversion. Mark Rawlings wrote an article of doing this conversion, I think you'll find it in the files section. I have pictures of the parts you need to make or modify, along with the wiring diagram you'll need, in the albums section. Read Mark's article first, it tells you about 90 percent of what you need to know as far as the mechanicals go.

Turbocharging a car from scratch is a time consuming process, and expensive *unless* you find someone whose done it for you. As I said, I know of two cars with Delta or Thema turbo engines fitted that are for sale. These would give circa 160 bhp + depending on their type and are available to buy.

To buy a standard Monte and to either swap engines, or to turbocharge the existing engine or to raise the power of a standard engine would require a significant investment in both time (both researching) and the actual doing, as well as a financial one.

Why don't you want to use carburettors?

Thanks for the comments

I am not looking for a short term project, I want a car that I can use and grow into At the moment I am just looking at all the options available Once I have purchased the car I will use it for a while and then decide on the plan of attack. Come on leo the main things that attracted me to the MC was the looks of the car and the simple mechanics where would I find that in a modern 2 seater sports car.

Will thanks for the advice I'll have a look at the files you mentioned


All the best Sal

Hello Sal,
A lot of people are atracted to the Montecarlo because it has potential for becoming more than it is and it has the heritage/bloodline to be able to hold its head high. Pretty soon they end up with round tail lights and prancing horses.
Hopefully once you have driven one for a while you will appreciate the handling and accept the limitations. They are quick enough to keep up with modern traffic but the twin cam engine and transmission are not capable of producing much more power without becoming very "peeky" and needing to be driven "full on" all of the time. The only way sensible way to get a jump in power is replace the engine and transmission but that is a huge job. However, I would imagine that a volumex engine (135 bhp) and transmission conversion would make a nice Montecarlo and be relatively easy to do.

What's wrong with fitting Ritmo/Strada 130TC cams, double 40 DCNF and a good exhaust? Result must be a torquey engine with apr. 140 bhp. Just like a modern MR2 which weighs about the same.

Thanks Otto,

Sounds like a good idea, and quite easy to achieve. a nice positive reply,

Leo,
I have a car for everyday use, this car is just something to get me from under the wifes feet.

It might even be a better idea to use Guy Croft camshafts because of the drive of the ignition which is different on a Strada/Ritmo engine.

I've seen:

Delta 16V turbo, Thema 8.32, Alfa V6 engines being used but all of these options cost a lot of cash and hard work. And the next thing you will be doing then is upgrading suspension and brakes which makes it even more expensive.

In my opinion it's a near original solution to use DCNF's on an Alquati manifold since it was a periodic upgrade for it. One of the problems when using other "hotter" cams is the relative low compression ratio of the Monte, about 9.3:1. Can be solved by fitting 1.6L pistons though but then again, it will cost money...

good day all

otto I am going to view a car today which has similar mods to what you have mentioned twin 40's etc not sure about the rest of the mods but Iknow the cams have also been changed. Just hope it's the right car.

Sal

[Otto-valvole-per-tutte]

Aha, am curious on the outcome of that.

Cheers

Hi all

I like the idea of buying a spare engine and building it up slowly, spending the money when it becomes available. If I wasn't going for a straight monte engine swap what beta would be the best for me to use as an engine source? Once I get the engine, what pistons, head and camshafts would you recomend?

I would like to go the fuel inj route so any thoughts on that would be welcome. I would like to start sourcing the parts and costing the work.

Last question would the proposed other engine be a straight swop or would there be mods needed to fit it to the monte.


Cheers Sal
