Custom Turbokit

what oil cooler, atf cooler and intercooler are you using? Still using the emanage blue?

[changchewsoon]

I sourced the intercooler from an Evo 3, the oil cooler is from ASR Performance and the ATF cooler from a Mitsubishi Pajero.

Yah I'm still using E-Manage blue for now, it is able to handle 2 extra injectors which is just nice for the turbo.

strange, i was told that the ecu will relearn over the emanage blue, custom wiring of plug and play?

I think we only know that for sure with USDM cars.

i'm not using any plug and play harness, splicing wirings directly.

just want to share the dyno chart with everyone here.

Nice torque

[changchewsoon]

thanks, its great to be part of the forum and getting know and see so many of us doing great things with the car!

[Kaotic Lazagna]

I'd love those numbers. Enough torque to get going with a full load in the car, and enough power to not bog down when the A/C with that full load in car is in use.

143 whp @ 8.5 psi

Wasn't it 8.8 psi? I'm still a total noob in FI, but isn't that pushing too much for the stock internals?

[changchewsoon]

Well I personally feel that this is very subjective as other various factors come in to play such as tuning, fuel used etc. Some would feel that 5 psi is as far as they would push, some 7 psi, some 10.

In our country, we have an option of either using RON 97 or RON 99 unleaded fuel which helps a lot to reduce detonation and ping.

My pistons are ceramic coated and the engine compression has been lowered to a 9.5:1 compression ratio. I do agree if budget permits, forged rods and pistons definitely is the way to go.

Just to share, we have a few Turbo Vios here whose running 14 psi all year long on stock engine and stock automatic transmission for the past 3 years, and the only issue they've encountered so far was fried piston rings. The rest of the engine and transmission is holding strong.

I think they're really insane, but in reality there are people out there who does it.

hahahaaha. If I were to ever have your set up, I wouldn't even get to 8psi. It only gets there at WOT, right? I drive very conservatively, so I'm not even sure if I'll even be making boost. hahaha.

[changchewsoon]

careful driver huh? yah thats good man, I'm also learning not to go WOT every single time. gotta take care of the fuel efficiency at the same time as well.

my current setup allows me to reach 8 psi in less than 3,000 RPM on WOT, on highway cruising the turbo will be reaching maximum boost even with partial throttle so yah i gotta learn to drive conservatively.

Car awaiting coilovers to be serviced, and the following mods will go in.

1. Okada coils
2. AEM water/methanol injection kit









Hopefully the coilovers can come back soon so the car can be tuned on the dyno. Charts will be up soon.

Nice update! the meth injection will help tons, hopefully you have the ignition harness to increase spark so the meth injection will be more worth while... Maybe you can prove the Okada coils are good for higher spark... one user here had a similar product and one blew out on him on a stock car.

[changchewsoon]

The FIC injectors cleared customs yesterday and arrived this afternoon while I was away in the office.

Together with the forged internals when they arrive, we should able to make some serious power when we crank up the boost.

The dyno results for the Okada Projects Plasma Direct coils is finally out, the results are more than what we expected as the dyno machine was able to pick up the gains both in horsepower and torque.

It took us less than 10 minutes to swap the coils and we took this opportunity to throw in a new set of plugs.


Autolite Iridium plugs

We did a base run and the car pulled 143.34 PS and 18.53 kg-m of torque at the wheels. With the Okada Projects coils fitted in, it gave us 153.01 PS and 19.45 kg-m of torque.


Blue: Without Okada coils
Red: With Okada coils

A first glance at the dyno chart it seems like the overall gains is not so impressive as we only gained around 9.67 PS and 0.92 kg-m of torque.

However we noticed that the gains are available throughout the entire powerband starting from 3,000 RPM all the way to the redline.

What caught us by surprise was not only the torque curve has been flatten, there is a peak gain of 14.22 PS and 2.02 kg-m of torque nearing the 5,000 RPM range.

In the past, the original coils simply just couldn't maintain sparks that were strong enough at the high RPM range to achieve a flatter torque curve. Seems like the Okada coils were able to get the job done.


Peak gain of 2.02 kg-m torque


Peak gain of 14.22 PS

Overall I'm quite impressed with the Okada coils, and would certainly recommend it to anyone whose interested in it. However, you would still need to find a good tuner who knows how to tune your car properly in order to enjoy the gains.

Besides the gain in power, the coils could also serve as a nice dressing item in your engine bay as well.
