Proton Inspira Power Mod

[punkingcj]

Hi guys,

I am new to car mod. Need some expert advice on this.

I am seeking for the extra top end power of my car. I am driving a 1.8MT and it tops out at 205km/h (need a bit more to pit against most modern cars). Coincidentally my father drives a 2.0AT Inspira and I am thinking of engine swap between the two cars since he does not really utilise its full power.

I do not wish to go down the BOT way due to the potential risk of destroying the engine and the issue of long-term reliability.

The real question here is, is it a simple task by swapping the engine? Or do I need to change/upgrade all other parts (wheel/rim, exhaust, gearbox or etc..) accordingly to handle that extra 200cc displacement?

Please enlighten me on this.
Thanks.

Remap ok?

205 kmh is good lah...BUT how fast you reach 205 kmh is another story.

honestly, is the difference in power really worth the effort?
its really not a significant difference in power.

Cant afford that lol... Why is it that? Power gain too little?

After remap will I be able to reach 210km/h at least? Sometimes need the extra top end power to fend off those 2.4L big cars from behind.

Too much effort for transplant?? Thought can gain extra horse or torque from the extra 200cc..

your 1.8 has the same bore as the 2.0. only difference is the stroke. power difference is +-30hp at the crank on paper and about +-3kgm tork difference. is it worth the effort? nope.

quick question, what was your RPM at 205kmh?

cant recall what the actual specs are but the difference is really tiny, probably 10hp at most!

wah. that's way lower than what they stated on paper. but yeah, if ts wanna swap the 4b11 into his car, he won't feel that much difference. and minor mods also not gonna give much gain unless he go for cam swap and other stuff.

Was going to say that, how often hit 205kph? Mine 190kph max speed cut......lol

Don't really remember... I think around 5k? I'll check again. What does the RPM translate??

No speed cut. The speedo reads 205km/h or more. Didn't read it carefully. I always travel North South Highway. Sometimes kena cucuk I'll have the tendency of hitting 205km/h. Lol

Thought will have at least 5~10% gain...

how much engine speed you have left before your rev cut. does the speed climb fast when u put in top gear going to 205kmh?

5-10% gain is not much. on butt dyno maybe you'll feel good for a while. then you'll be asking for more.

Can't really recall. I think it was 5k++ RPM. Should have a bit more left before redline. Everything stock.

Speed climb is definitely faster than my old man's 2.0 car.

Hoping to gain extra top end power to match those 2.4 cars. Lol..

everything still stock? try decat, changing the extractor, swap to better flow piping and mufflers, drop in filters?
