Mi16 Potential?

[kaich 6 1 Cars]

before all: I used the search function!

the xu9j4 has less potential of xuj0j4 but how many bhp (without turbo ecc) could reach mi16 engine?

from what I've read it is possible to reach 200 bhp but with a lot of money (TB's ecu ecc), right?

with a fully rebuild and "traditional" tuning (cam, exaust ecc) how many bhp?

cheers

all very much depends on budget and use for the engine, both the 1.9 and 2.0 have been used in BTCC and Rallying at around 280+ bhp

holy s##t! that's a great result!

for a daily car (so no racing cams etc) and a budget of 1000 pounds (for engine rebuild) how much bhp can I reach?

for 1000 pounds you could rebuild the engine.. and wont have muchleft over.. so 160 bhp.

Holy s*it! I'm seeing ME 2 years ago.

 

Kaich:

 

I think you ought to plan first what you want to do with this car, i.e. race it, rally it, just use it on the road or a blend of 2 or 3. Then plan how much time and money you have to invest.

 

If all you're interested in is 'how much power it can produce', then I think you are approaching your dreams the wrong way. An Mi16 engine is great unmodified, whatever car it's in. Depending on what you want to use it for, you may be better off spending your money on improved suspension, chassis and steering geometry to make better use of the power you already have. This will guaranteed make the car quicker in all but a straight line, and more rewarding to drive.

 

That is what I would do with £1000; I wouldn't even touch the engine. People like Colin Satchell (eeyore) could make some fantastic mods (if he has the time) which would do wonders for your car's handling. I'm sure others would recommend other suspension mods and be quite capable of doing them too. But from what I've seen today, Colin's knowledge and skills are first class.

 

If you insist ( ) on spending your money on your engine, then £1000 would probably get you triplecut valve seats (along with perhaps fresh valve guides and lifters), some subtle headwork and a mild road cam (Mark Shillaber and QEP spring to mind for this), which would net you some more grunt in the mid range, and maybe 10-18BHP.

 

If you're just on a hunt for BHP (like I perhaps was), then you'll need at least £2000 to start playing with throttle bodies, aftermarket ECUs, fine-tuned exhausts and perhaps forged pistons etc which involves engine out.

 

My project is going to be around £1700-£2000 all in, with no throttle bodies. I'd choose very wisely what you do with your money my friend, as thinking back, I would most likely have left my engine alone and worked on getting the best from the existing power by improving the chassis & suspension first. I quicker route to SPEED in my opinion; IF that's what you're after.

I am going to sound like a boring old fart, but for a daily drive car forget peak power. Go for reliability and driveability. I did a full Mi16 rebuild with a fast road inlet cam and it cost a lot more than £1000, however it will sit in traffic all day without issue, it can be driven round town easily as it pulls well from low revs. All of the cars I have driven which have been tuned to the upper ends of their potential have been horrible to drive unless you are on an open road or tack and using high revs.

 

I am with Dr Sarty, spend your money on refreshing the suspension and replacing suspect parts on the 8V engine. I did the Mi16 engine before the suspension and it transformed the car more than the engine. Yes the Mi16 in a 205 is huge fun, but not if you cannot use the power without some hedge bound moments.

to DrSarty:

 

I know what you mean, let me explain:

IMHO 180-200 bhp is the right power (and also power limit ) for a car like 205. More bhp in 205 means quaife differential, strong driveshaft, racing bits etc.

of course with a lot of money you can reach power like 300bhp+ but IMHO if I want 300bhp+ I look for another car.

In fact if you read my first post I wonder that 200 bhp is "my dream" for my car, but not what I'll reach at now.

at now I want to do a mi 16 conversion with a engine rebuild. If I have more money, I look for new cams etc.

 

You right mate, an handling car is a good idea, more than an huge engine, but I'm a lucky guy, my car has already a full set of koni sport, eibach spring and as you can see, a set of grooved and drilled brakes (with braided hoses).

 

ps: I'm reading your "project sarty", 100% awesome!

 

ps:sorry for my rusty english

Hi mate

if I've read this post 3-4 years ago I've think you're wrong, but at now I'm think you're right

Maybe my post was misunderstood,as i told to sarty I don't want huge power at 7000 rpm and a dead engine at 2000-3000 rpm

I'm speaking of a daily car, so as you said means not a huge power, but a handly car with more bhp than 130 (IMHO)

So in a daily car it's better a good torque, not a huge power, you know what I mean?

many people forgot that at least (power= torque x rpm) so if you want more bhp the easiest way is to increase rpm, but in a daily car this don't work. in a daily car IMHO it's better 10-20 bhp less but more torque, don't you?

Even a 105kW DFZ can destroy a BE1/BE3! Driving any BE1/BE3 equipped car without a Quiafe (or other LSD) is like playing Russian Roulette. Those crappy sun gears can let go anytime! A friend of mine was doing 20km/h, driving in a car park, when his let go.

I agree, if you want a reliable 205 you need to ditch the standard diff. I went through two diffs before I got the Quaife one, which is a PITA having to be towed home. and let's face it they are all pretty old diffs now.

If you can find a decent mi engine which doesnt require a rebuild then you can expect 180-190 bhp from Tb's and a inlet cam at a cost of around £2000 (inc mapping) i bought new jenveys fuel rail linkages for £550 off ebay also 2nd hand dta ecu with loom £350 with the other bits and install (a good m8 returnofjim) it came to £1400 then i had the mapping done at £350 with a total of £1750 for my set-up. The power is much better at low end and mid range and doesnt have that lairy kick in at 4000 rpm which did cause more wheelspin before in the dry and was way better around curborough on the tyres. My Bhp is at 181bhp a little under then what i was hoping for but it could be the standard manifold and restrictive downpipe thats holding it back a little. The results are good it can do a 14.45 qtr mile at 98 mph and just listen to the noise click below.

understood.... this mi16 conversion start to be really expensive to me a decent LSD is around 500 pounds..... so this conversion will take me many many times (and many money )

 

partially OT: a brand new set of gasket for xu9j4? I wonder it is useful for an engine rebuild, don't you?

I see in the peugeot service site (code 197J3 ) but it seem really expensive (around 160 pounds )

 

dazEmad:

my mi 16 need a rebuild so... at now i can't find to tb or what else ....

impressive your video, it seems a car more powerful than 181 bhp! as you say it seems a torquey engine
