My Spec
4G93 with Mivec
ECU code 0450
175bhp at the flywheel
Mivec head
Mivec inlet and throttlebody
SAFC
RSPEC Shift light (activates mivec)
2.25 inch exhaust piping
2.3 inch exhaust with 2.5 inch outlet
K&N drop in filter

Sifu's, My question is how can i make it to 180hp to 200 hp on flywheel?
I tot 1.8 mivec engine should be 180++ hp.
Any suggestions and mods need to be done to achieve that horsepower please do teach me sifu.
And around what figure?

Thx in advanced sifu

1.8L mivec got so powerful??..

cylinder head pnp already??...
try switch to a better piggyback ecu such as emanage ultimate or a standalone ecu.... recallibrate the setting.... possible to net extra 10bhp...
and, mivec should have at least vafc rite??... safc can support mivec system??...

Yeah, a low pressure turbo can pump you 10HP to 20HP easily.:biggrin:

No need buy all expensive and new stuff, get those working second hand stuff will do. :biggrin:

u can't get the high output is because u still running with stock GTI ecu.
Mivec stock ecu is ready with 2 stage air fuel and ignition timming mapping to support on high cam.
u need to a piggyback on ur set up, or go to get mivec full wiring and ecu to support.
good luck.

Makan minyak like no body business due if i install 4 throttle
If u want power n dont wanna sacrifice a bit then better u use stock mivec enough and dont ever think of 200hp , this way u can save a lot of fuel. Juz for your information im running on 4throttle everyday to work n travel around.

Yup,,,ppl talking about building 200hp mivec but dont want to install 4 thrott and cams. So where will the power come from :confused: My advise is, to have a "realistic" goals it must be supported by "realistic" parts.
