First and foremost - Thanx mods for this thread. Now getting back to business: - Companies spend billions of dollars and months (if not years) on research and development of engines. And then we have smart asses (one of them being me) who try and modify an engine by dropping in some bits which takes a couple of weeks to do - expecting miracles to happen - Lets stop fooling ourselves - stop acting like an Ostritch. however much you try and hide your head in the sand the lion is still going to see your rear end, and grab it. Let me first clarify that the object of this thread is to discuss engine modification carried out for increased power to cars which will be used as daily drives and not purpose built for drag and competition racing. Building cars for drags and competitions have been discussed at length in several other threads. My sincere request to all who read and reply to this post would be to keep the topic in mind before putting down their comments and suggestions.
I have gone down the turbo and engine swap route. havent done both though. Maybe I am getting a little old (read less patient and lazy). In my experience (the little that i have) I would have to say that at the present moment, with the availble hardware at our disposal, and keeping in mind reliability factor, turbo charging a car is the not the most sensible way to get more power.
Mclaren - I am not discouraging anyone. Beleive me i will be the first person to try and help a fellow car enthusiast. But when I have been there and done that I would only like to point out the perils involved in turbo charging a car. You can listen and avoid yourself a lot of trouble, pain, time and money or vice versa. Infact anyone in this forum who has attempted this diffcult and truly challenging task has never been discouraged by me. I have only pointed out what precautions need to be taken. Never once have i said - Pull it out, it aint going to work.
I completely agree that building something no one has, does give you thrills, but the question we need to ask ourselves is - Am I building this to get a kick for 13 seconds or am I bulilding this to derive pleasure for the rest of the life of the car ? An aftermarket turbo car is not reliable enough atleast not in our country. You will not want to take your car on a 2000 km trip knowing fully well that you might end up blowing the engine to bits.
Running a turbo also necessiates the use of good gas which is available only in bigger towns. I run a 4G 92 Mivec and recomended fuel is 100 Octane. But by running lower octane it does not mean that the engine will blow up. Once the ECU senses that the engine is knocking due to bad gas it will automatically retard the timing and reduce the performance. Thereby reducing any further harm to the engine.
Most JDM half cuts available are direct drop in kits for the cars available here. When you get a half cut you get everything, including the wiring harness, ecu, suspension brakes, steering components etc etc. I am not saying that all half cuts are in excellent condition. You need to either go and inspect the half cut - most available in Singapore and malaysia - where language and communication is not an issue and flying to and fro is cheaper than flying to Delhi and back on regular fare. If you have a good source in these countries you can save yourself the trouble of going there. The best place obviously would be Japan to source these kits. The point I am trying to make is that since these kits are direct plug ins, there is bsolutely no need for any cutting, chopping, welding etc etc. Also the suspension, brakes etc. supplied with these kits are beefed up keeping in mind power of the engine.
The only way a turbo is going to be sucessful is if we have the proper hardware. First in the list will be a dyno. Other hardware has already been mentioned and I will not waste any more time. Ideally a stand alone ECU will be the best option, provided some one good knows to tune it. But this again will cost you 1000 dollars if not more.
Lets make a list of components and their cost, you need for turbo charging and compare it to a cost sheet for engine swap. I think we will get a better picture then. We have members on the forum who have done both projects.
All I can say is that till now after market turbo projects have run much less reliabily than engine swaps. I have a 175 BHP car which was once 87 Bhp. I have gained 100% more power and I can confidently say that money spent per BHP with lesser hassles has driven me to the conclusion that engine swapping is a much better option.
And therefore I have voted accordingly.
