| bro wlvrn, okay lets think outside the box you want sufficient power for overtaking but not racing eh? if you want overtake a car which was 1km away you need to race first then overtake hehehe... pravindastar running on M40 1.8 E36. I can say, his car is unbelievable. He always run with us (2.3 and 2.5). Why? because we dont have enough balls to run over KMH180 (during cruising). WHAT I SUGGEST Take to the workshop and ask mech diagnose also tune you 1.8 to max. ie: adjust throttle body, upgrade fuel injectors and also fuel pump. This can skip your brake upgrading. Once you done... you will feel satisfied, look for ah foo Optimum Kayu Ara. Cost to do this might be around 500+- IF NOT SATISFY Okay, SC or TC you need more than 5k. furthermore you must do in a correct way, you need to find compatible intercooler block, SC or TC manifold and most important piggyback ie: SMT6, Greddy etc. The piggyback also cost around 2k. Conversion? OR you can convert your entire engine to M42 or M44 1.8 also which halfcut cost around 5K, installation lets make it 2k MMMMMM..... Good luck |

cannot believe you guys are trying to convince someone to change to a m20b25....!!!!! on a 36 somemore.... actually a 1.8 to 2.5 conversion is not allowed tecnically but on a bmw jpj allow it most times....i know lots of guys doing this some even 2.8.....some people declare and some don't and just continue paying 1.8 roadtax..... as for a m20....please enlighten me on the last time someone actually saw a perfect m20b25 which could idle correctly.....it takes far too much time effort and money to get one to be close to perfect....its old technology brothers....! |

| chris, how much is the conversion cost? easy to get JPJ's approval (displacement more than 30% of original spec)? BTW i'm using E36 with M40 engine and so far the engine is in good condition. |

| What upgrade can be done to fuel injectors and fuel pump for M40? For throttle body, I assume as long as your valve opens max when u floor your gas pedal, it's good already right? BTW, I think pravindastar's one is M43, not M40.  |

if you are running an m40 the first mods u should do is as follows : 1. Electric fan - use the one from an e36 as it is plug and play(some wiring required though) to replace your fan clutch to reduce the mechanical load on your engine. Cost: RM 250 for the electric fan from chop shop and RM 150 for the wiring. 2. Lighten your flywheel - again to reduce the load on your engine. Remove 500gms frm you flywheel, remove more and you will lose torque. 3. Upgrade your injectors: Go to the chop shop and look for the injectors from an E34 520i 24valve. Better flow rate and finer spray pattern. Expect to pay RM 150-200. Plug and play, just need to retune your CO to 1.5. 4. Performance chip: this will truly release those hidden horses in your M40 block. 5. Piggy back ECU: one up from the chip as you will have full variable control over your fuel map and ingnition timing. 6. MAF conversion:Mass Air Flow meter, to replace you AFM(air flow meter), this is to be done with no.5 as you need the piggyback ECU to decode the signals from the MAF to your existing ECU. 7. Forced induction: the holy grail.......supercharge or turbocharge your M40 and give the six-potters a run for their money! |

Oooo nice compilation of things for me to look at. THanks bro! 1 and 3 seem simple enough. For 4, where to find the chip? Can't simply use some generic ebay one right? |

| ok lets start. by now all of you should know the basics. Why convert ? who knows what state the halfcut for a m20b25 could be in ? Dont forget these things are 20 yr old halfcuts. Unless you plan on rebuilding the engine dont waste money. Bolting on a SC gives you ample low down torque plus the sets here have an on/off button so you don't need to have the SC spooling all the time. But beware the effects of having bolt on forced induction equipment on a high compression engine. Prolonged high boost can be detrimental plus wear and tear is high. Do not forget the m40 is an engine that wears out fast. Cams wear themselves out after 200,000 km or so. The m43 was a redesigned engine which does not suffer these problems. Oh and head/profile/valve gaskets tend to go easily on a m40 itself. These problems cannot be evaded as they are inherent in this engine. Plus the fact that a timing belt is used is cause for concern too. Heat already damages the belt super fast but forced induction would wear it out faster. But all this PALES in comparison to having a SC/TC bolted on. you would be smoking the hell out of Chris Eunos's 325 anytime anyday. I drove an E36 m40 auto with a mosselman turbo bolted on boosting at abt 0.38 bars of boost. It felt like i was driving a bloody 328 !!! and there was no lag due to the low boost. Ok now Turbo Sang in Sungai Buloh (just past the tol after One Utama) does a exact replica kit of the DA kit using a Levin Supercharger (recond). Price of stage one is RM3800. Send in the car in the morning and collect in the evening. Stage two kit consists of additional bigger injectors and stage three has a intercooler i think and some extras. all in all stage three (complete package) costs RM 5k. Should give you close to 200 hp on an m40. PLus it has a switch for turning the charger on/off for fuel savings when not racing. |
