Project Porting! Pics!

[sleepydsm]

I just cleaned up my 14B last night. It really helps to use nice solid carbide bits. I "borrowed" them from school and they HOG through cast iron in no time. I then used a porting kit that consisted of sand paper drums to smooth out everything. Looks good!

I just figured out how to do an EGR delete using a standard DSM block-off plate and a quick hack to the stock ECU:

add to <romid>.xml file in EcuFlash:

<table name="ECU Periphery2" category="ECUPeriphery" address="fca" type="1D" level="1" scaling="Hex16"/>

Then change the value to '0xEDDF' for ECU Periphery2 in Ecuflash. Thanks to MrFred on EvolutionM for this. This will clean up my engine bay nicely!

I also just ordered some high-pressure throttle-body seals from works!

Way to pollute! j/k. I think that's awesome how you can go in an mess around with stuff in your ecu.

I got my intake manifold and throttle body back from buschur racing yesterday. There was a mixup and they shipped it a week after they told me they did, and before I could even think of complaining, they OVERNIGHTED it to me. I love those guys.

Here's some pics of the throttle body. This is just a stock TB that's been bored out to a full 65mm all the way through, and a new butterfly installed. Sitting next to the stocker it looks similar at the opening, but the stock one gets smaller as it goes thowards the butterfly.

This is bolted to the ported manifold, 65mm also. Wide open all the way through!

Next to the stock, unported TB. Same from the outside, but the butterfly on the left is bigger:

Here is a rough comparison of the size difference between the 65mm stuff and the stock, unported manifold inlet (using my thumbnail for size reference):

Good stuff... proflow is doing some throttle body porting + new butterfly for the 4G as well... it's 250 including shipping I think and has proven gains of at least 5-6whp, one kid posted 17wtq difference in 4th gear on an auto as well.

Looks cool, if you don't mind me asking what does Buschur charge for that? So I can compare to proflow, and also what kind of gains are you looking at with it?

The intake manifold runners are ported out a bit as well, port matched to the head.

Again with the vague size comparison:

While I'm doing this, since I figured out how to remove the EGR checks in the ECU (see above post), I am ditching the EGR valve, the charcoal canister, and the lines associated with them. Should clean up the engine bay a little bit:

ditching this bracket as well:

Goodbye POS that cut the hell out of my hand!!!

Finally, an action shot of this little project....I love my 4G63 so much that I like to hug my engine and sing to it....'hold me closer Tony Daaaaannnzaaaaaa!!!!'

I stopped smiling soon after this, as I began dropping sockets and bolts into the subframe as I began to install the new manifold. I then broke off one of the bolts in the head, what a fcking b*tch of a job. Oh well!

looks good

This is just a basic port job on the intake manifold, porting the runners and boring out the inlet to 65mm was $75. The TB conversion/boring was $300, I could have had it done for $300, but I would not have done this if I had not seen Dave Buschur post the solid whp gains from this little project, so I commited myself to give my money to him, instead of the other guys undercutting him and posting zero proven power gain results.

I am expecting a SOLID 15whp from the IM/TB combo, through the entire rev range. This will complete my porting project. With the exhaust mani (5-10whp), SS o2 housing (10-15whp), and this, I am hoping for a full gain of 30-45whp. My car made 295whp on just pump gas, so I'd expect ~330whp. I also bolted on the Evo IX turbo though as well, which is rumored to be upwards of +20whp, so I have set a semi-realistic goal of 335whp on straight pump gas, and have lofty dreams of 375whp with alky. We will see when I re-tune this thing.

So you have the know-how on going into your EcuFlash and changing properties and values? Or were you grabbing information gathered elsewhere? That's pretty frickin' awesome that you are able to do that stuff in the ECU on them things.

Looks like you're going to have yourself a sweet ass sleeper in the near future with some good power!
