nmwisima's '96 Miata

[domi]

Don't know about the Miata engine and don't know how relevant my info is, but i'll try anyway: On the blacktop, the ITBs and all, on a shorted check connector [ECU isolated from trying to sort the timing on it's own] it's supposed to be exactly 10° advance from TDC. With the check connector open the ECU should advance it by a few degrees - mine did with 3°. Hope it's somewhat helpful. I believe general rule-of-thumb is 10 before TDC to be optimal, unless you're fiddling with it on purpose.

Sorry Apolan, but your NA fetish sometimes skews the facts. The grip and balance of a miata with a small turbo will be exactly the same as an NA miata, only have double the power potential and useable torque.

Stock base timing is at 10 degrees. Set it to between 14 and 18 degrees to lose some top end hp, but gain midrange torque and throttle response.

as i said many times before, to each his own. I just fail to see the point in having a 200+hp turboed miata. Might as well buy a different car.

Apolan, what else is in the class with such handling/weight/wheelbase characteristics that can hold a candle to the Miata... Now figure in price... I believe the Miata is one of the very best sunday driver tuning bases. Sporting spirit does not require sporting fabrication/prices/performance necessairily, but having the spirit in the car initially you can afford the performance quite easily, who cares about the other two?
It reaches a matter of personal choice and supposed santimental affections. I per se love the hachi roku although the only performance characteristic i can point out to support that statement is the potential for massive cornering speeds... The Miata is surprisingly similar in that respect.

Its just me man, im just not such a fan of tunning the hell out of cars. No mater how fast they can go. Okay sure it is a whole different sport which is fun in its own right.. Just look at what soara did with his hachigo. Will it be fast? no doubt, probably three to four times as fast as any of ours... Particular car has been made with an intention and as a whole. Add litlle bits to spice it up,sure, thsts aways a good idea; but once you start swapping suspension and going all crazy on power - well thats just a whole different sport as i mentioned. and when you're there, you might as well start building your car from scratch. Im charactarising a bit, but you get the point.. but theese are just my views. As i said, some people find it fun to make any car they like as fast as possible.. which is cool for racing or some sleeper-fooling-around; but in my opinion you just loose all the "balance" (in sense of power to (chassis/weight/suspension), the spirit and intention that the car was build with/for.

Its not really into the project matter, but its something.

After almost 1 year o fconsumption measurment between 15 and 16,5 litres / 100 km from a stock 1.600 cc engine,

I finally got an 11,5 l/100km!!

300 km and 80% in the open road, which shows clearly its not really an engine problem but a matter of driving conditions.

this is still way too much man. Just doesnt seem reasonable to have 11,5 l /100km on the open road. usually 1,6 4bangers have around 8 at most.. some hondas can even go around 6-7 l/100 km on open roads.. either somethings off-tune under the bonnet, either mazda cant make engines or you have a really really heavy foot my friend

[nmwisima]

No they cant do it man.

These ar mostly fault or overestimated counts by the owners.

Look, maan, a very good friend of mine used to have an EK4 ('97 Civic Vti), 1.6 DOHC VTEC 160 hp. The car weighs more than your miata by cca 150-200kg. He used his car to drive to work and back. Needless to say he has not bought such car to drive slowly. And he is doing cca 80% pen road and some 20% city driving, where his work is. He had reciepts from the gas station and on them he wrote the milages he got from that (full) tank. Calculated, not one of the recipts showed consumption being over 8,xx; most of them being 7,xx l /100 km. He now drives a much heavier, 200 hp prelude and on that same routine he still has lower consumption than you got. Unless he rally races the whole tank away.

Even when i drove my 130hp civic, which is similar in design as theese engines i guess (1.6 dohc).. i did cca 80% city and 20% highway and open road - and i usually got 8,xx, 9,xx in winter.. Hav not calculated anything for the ae yet.

Its either that or you greeks have very thin air or very bad gas down there MAAAN.

in addition, my fathers e39 525i 192hp and 1,6 tone bmw uses cca 12l/100km almost exlusively city driving.

I really dont understand how can you get such low mileges..
