Dude , i sincerely request you to kindly take your time and read twice before you post .. Its kinda getting difficult to understand your posts .. And adding more to the confusion ..

Who even said anything about a civic here ?? The D15 is the OHC vtec engine man .. NOT THE CIVIC ..

I guess the main purpose of this thread is to warn about what bolt on parts give only MHP and what actually give out bhp gains .. Its in this context that the intake manifold , ECU of the Thai Vtec (which are sold as stock by the company and no aftermarket upgrades) engines came up .. In that case according to what you say , even changing the stock air filter , headers , exhaust would also be considered as a SWAP .. And i dont think you can achieve 200 bhp by doing any of the above mentioned mods by you certainly not on a 1.6L engine ..

We are talking about TWO SAME engines with one or two components changed in order to cope up with our fuel availability in India ..

I dont know if you know the state of affairs in India , but i would anyday prefer changing the intake manifold , ECU from a thai vtec than letting a tuner port or work on the VTEC engine .. With these changes you are guaranteed of the bhp gains .. And yes the engine specs and design of the Thai JDM stock engines (engines being sold across the globe except in india) and the Indian VTEC engine are the SAME .. Except for these parts .. And keep in mind that you aren't still opening the engine ..

I request you to kindly read the posts twice before adding more and confusing the rest .. Also please do put up facts and figures and not just arbitrarily shooting off talking about 200 bhp gains and top fuel dragsters .. For more info on the Thai engine and Indian engine , do make use of your friend .. Google .. Or search the forum , its been posted already ..
