My dyno test & problems

[DanPromote]

Just went for to dyno test my car yesterday as I want to sort out any problems before my quest for power begins. I noticed some problems during my outstation trips as the engine starts misfiring from 140-160kmh & goes out of breath at 160kmh. Just as I suspected the dyno test graph revealed that the power goes down after 4800rpm and seems to be running on 3 cylinder at times instead of 4. It is possible that either the coils need replacement or worse come to worse, a top overhaul. Since the coils cost RM100+ I'll replace that and see if it helps. I've also changed the spark plugs to check if it was due to this but the problem persists. Any one faced the same problems that I'm facing before? Btw don't ask for my dyno results.. very malu to show..kekeke wait till I've solved the problems first. Estimated power on wheel for a perfect working condition one is around +/- 80-90hp (considering it is 115 on paper) Some recent dyno tests done (power on wheel) :- Myvi - 65hp (stock)Proton Neo - 96hp (stock)BMW e36 318 with turbo kit (no piggyback ecu, only fuel regulator) - 130hpBMW e36 with 1JZ conversion (stock 1JZ without mods) - 260hp!!! Mazda 6 2 litre (stock) - 112hp IF the worst of my fears are true then it's a toss between a top overhaul, complete overhaul or a 1JZ conversion... strongly being pulled into a 1JZ conversion by my tuner if I need to spend that kind of money to overhaul my engine (suppsed to be trouble free, quiet and damn powderful ie.stock engine internals can withstand up to 600hp!)

IMHO, if it turns out to be bad, just sell your car and get something better. In my experience, it ususally works out cheaper, safer and with less hassels to just buy a stock car with the performance that you want and leave it well alone.

But if you really like your car and had to do an engine conversions, i would just stick in a 325 or 328 engine.

On firing on 3 cylinders, with my other car it turned out to be just a bad spark plug.

All the best.

The e36 turbo with auto transmission has recently installed a piggyback ECU. Power now up to 152hp on wheel, could be higher if the owner wanted it. Btw, stay away from Kepong tuner.

wah..1JZ stock makes 260bhp at the wheels huh?? that is one spanking engine man..have u tried out the 1JZ e36 urself?? 260whp in a rear driver is awesome if u can deal with the tail,but can the driveshafts take the punishing? if yes,then its a good conversion.

 

[DanPromote]

yea man... the stock 1JZ dyno was done at Millenium Auto Sunway.. if u're there u can ask my friend Joshua about it. So difficult to gain power for an e36 when a stock engine without aftermarket ecu already churns out 260hp on wheel! The only problem... it is not a BMW engine but if one can live with a Japanese heart then very good conversion... currently around 4-5k for the halfcut and another 2k for workmanship.

Anyway I'll need to check whether I can solve my current problem first before thinking so far ahead. Hopefully it is a small problem... not willing to sell the car now coz already did a lot of work on it and the 2nd hand price for e36 is very low.

325-328 engine transplant also out of the question considering it cost almost 20k for a transplant and a 2nd hand 328 only 40k without negotiation! Imho it is more worthwhile to get a 2nd 328 car.

The 318 auto got 150+ with an ecu? Not bad, considering it is an auto and using a small turbo. Is it the same one we're talking about? The car was in bad shape before tuning... spluttering all over and sererely lean on fuelling as no fuel regulator or ecu was installed prior to that. Then again... turbo kit + ecu + installation still lose to stock turbo engine by miles for around the same price

 

[ALBundy]

Yeah, the car was dynoed at Joshua's place. Initially was only running on an adjustable fuel pressure regulator, car was knocking from half throttle onwards, AFR was 14.7 which is extremely lean.

With the Unichip Piggyback ECU and a turbo module controller, the problems with the car were resolved and the owner is pretty happy with it. The car can be easily tuned up to 160hp on wheel Its running on a Garrett T25 AR.48 turbo. If its a manual, the on wheel hp can easily breach 170hp.

Bro, putting in a jap engine is the easiest way out. Have seen the IJZ and SR20 engines in e36 before, but IMO you will be better off selling your e36 and get a JDM

 

[DanPromote]

kekeke so u're also against Jap engines huh? Actually a true BMW purist won't put in turbo kit also...the same could be said.. might as well get a Jap turbo car than putting a turbo kit.. well.. to each his own. I guess as long as the owner is satisfied with his car then who are we to question what turbo kit or engine he uses?

I'm against using Jap engines if I want to sell the car in the future... the price will drop even further than it already is, but if I want to keep it then it seems to be the best solution under 7k.

 

[ALBundy]

Putting in a turbo doesnt dilute the marque but rather enhancing it. Turbo kits like Mosselman, ESS, Active Autowerke are all popular with BMW owners, similarly supercharger kits like Dinan, Vortech and etc as well. And there was a BMW with turbo many years ago and now the 335i, so its nothing extraordinary to say the least.

Putting in a jap engine is well....an entirely different story. Nothing against Jap engines, I think some of them are great stuff ie; the S2000. Its just that I personally find it to be a big turn off when the hood is pop open only to see a Nissan or Toyota Engine under it.

 

[kevster30]

Lately there seems to be a lot of quest for power on this forum.......bonus time of the year issit?

A lot of emphasis on 'on-wheel-hp' but still only the same old dogs turn up during track days.......I really wonder where all these 100++bhp on wheel cars end up running?

Depends on who u're talking to.. some even say BMW cars are meant to be kept stock standard, who are we to mess with cars which have been tested and engineered by BMW?

I don't find it a turn off whatever engine I find in the engine bay.. as long as it has power and handles well, but that's me... most BMW enthusiasts will shake their heads.

In terms of car value yes you're right, a bmw with a turbo kit/supercharger is definately worth more than a bmw with a jap engine although on the road it may get whopped by it.

 

[theCROW]

i also don't agree udm with jap heart
anyway few things for sure about moded cars:
-u can't win all the time
-there's always a car faster than u

Some prefer to keep their BMWs stock because they dont know how to mod it. If everyone who owns a BMW has kept their cars stock, tuners like Hiop, AC, Remus, Eibach, Shrick and etc would have closed shop by now. So, there you go, plenty of folks mod their cars.

Dont be surprised a properly modded BMW with turbo could whoop a stock SR20 or 1JZ. Anything is possible...provided you know what to mod and what not to mod. And of course, how much you are willing to spend. If your have a low budget and want high hp then of course plunking in a Jap engine is the cheapest way to go about it. But then, other than yourself, everyone else will be laughing at you

Anyway, when are you gonna to mod your car?? Nah, some pictures of my new toys.

Someone told me this before......

"it does not matter what they have.....it's how well you use it counts!"

Yes, see u guys on a trackday to prove the above.

True also...like what Spiderman says. OKie will wait for Dan to plunk in a Jap heart first kekeke

Make sure you are not go karting somewhere else on the next HPC track day!

 

[DanPromote]

It's not that they don't know how to mod, but prefer not to mod it. Wanna get a faster car some say may as well use the money and get a M3 or M5 or a Ferarri. Put a turbo kit on a 328 it is still going to be a 328. There are always different opinions to car modding, neither one is right or wrong, in the end it's your money and how you want to spend it is up to you.Actually quite a few forumers have Jap engines on their BMW, not to mention in other countries like Thailand it is a norm ... I haven't seen anyone laughing at them

Now my priority is to sort out the problems first..only if it can't be solved I'll think of other alternatives. Cost wise if the engine is sound my priority is still a turbo kit or supercharger but if I need a replacement engine then..hmm... I may go to the dark side!

 

[Jules]

Dan,
Since solving a problem is your intention, sticking to standard will allow more mechanics to get it rite since it's standard.

If you do a conversion - I think you are stuck with the guy who did it......if trouble strikes. logic or not?

Some will disagree, but power is never free. ( nor easy... )

Bundy,
Sorry, had to miss last HPC as it was the final 2 rounds of the Malaysian ROK Championship.....got to score the points! Nov next one rite? wuhoo!

dude..whatever u do,its ur car man.what's important is do unending research and find out what is best to fill ur needs.take it slow and don't rush..
..and i don't understand all this fuss about trackdays and driving skills.cummon man..eveyone has their own level of skills,Sepang attendee or not.what's important is have some common sense,know ur own capabilitise and drive within it.treat every drive as a learning experience..powerful car or not,if u know ur own limits,i don't see the problem.
remember,with great power comes great responsability..such a cliche,but its true.

1JZ rocks!!! 2JZ even better...

 

[DanPromote]

Yes definately I'll stick to standard if the problems are small enough to fix. However if I need to do a complete overhaul then my hands will start getting itchy due to the options available.

 

[ichiwan2]

Upgraded your brakes yet?

 

[DanPromote]

halfcut comes with brakes I'm one who gets everything ready before the engine is plonked in. Now already upgraded to height adjustable coilovers on 17in rims.
