Best possible figure?

[whatjdm]

Before I make a fool of myself, let me get this correct. The official stock B16b in the EK9 makes 185bhp? BHP here meaning the amount of power produced at the engine and available for use.

However, like with all cars power is lost through the drive so a more accurate measurement of how much power the car has would be WHP, the power at the wheels or amount of actual power the car can use and this figure I think is 150-160whp. I got that from reading a few topics on the forum already. Would be this correct?

Moving on to the actual question, building a N/A car that has high whp (200-300) then would be an achievement. Being limited with money though, and wanting to keep the natural state of the car (keep the B16b) and feel of the EK9 without heavy mods such as stroker kits and turbos, how possible is this to do?

My current idea is to add aftermarket parts, go light where I can, tune where needed and shed weight where possible.

I'm basically looking at better engine components, intake/exhaust systems, handling and braking and mapping the ecu to get more from the parts.

What figures can I expect, at what cost and what parts should be on a potential buying list?

Thanks.

What do you mean by 'limited funds'? If you are staying N/A forget anything else, your first mod should be an MFactory or similar close gearset (flywheel/clutch/maybe 1.5 way LSD-while the box is in bits).

Correct also

Yes it is possible to do it keeping it 1.6 L N/A, but money is an issue here, it's still costly to reach 200 whp, and do not neglect the reliability factor to go there, so have in mind that and make proper choices(tuners, parts...) However, your project is what I prefer, I always been a fan of 1.6 L modded N/A reaching it's limits!!

As for the parts you should get, consider forged pistons and their peripherals(lots and lots of choices), some bigger cams like Toda or Skunk2(S2 Stage 2 for extreme high end power) , Valvesprings/retainers, throttle body(68 or 70 mm), thin head gasket, exhaust/intake manifolds, intake/exhaust, ECU like Power FC or AEM EMS.
You should also work a bit on the head with port and polishing for compression....
And keep in mind that the ECU should be tuned by someone who can really tune it, not just playing with it, otherwise you will either damage your engine or get only minor increase in performance.
The cost depends on your local market/labour and shipping costs........so I cannot help with that, however as I said expect your pockets to feel it.

The actual hp cannot be known in advance, tuner, parts, engine current wear, climate conditions are all playing their role, but the logic says you should reach 200 whp without problem if the job is done nicely

I take it the loss between n/a cars and Turbo/Superchargers between flywheel and wheels varies? And if so by how much is it like 20% or there abouts???

no i think the losses would be the same as there both going through the same gearbox

I suppose so but what about turbo lag,would that not have some effect on it???
