Do you smell what the rock is cooking? Stage 1 regrind.



Should be interesting after i get the t3/t4 turbo on and the engine tuned.

what were they reground to?

nothing too drastic.

no dice.

What are those gonna do to the idle?

What is your engine management going to be?

The grind isnt enough to really upset the idle and the stock ecu can handle the cams. But i have the Apexi ignition timing controller and the s-afc II.

Oh, right on. Thats sick!

How much, if you don't mind me asking?

So the top numbers are the new cams and the bottom are the stock cams?

It was about 65 dollars a cam to have them reground. Once they got the cams, they had them for about a day then sent them back.

It looks like the bottom is the stock form and the top is the reground numbers. Not a big change at all but it's only supposed to be a 10% gain in power.

Hmm, 10% eh? 21.5whp and 25.1lbft is a lot of power gain for $130.....

$65?!! Whoa. I wonder if they can use N/A cams to regrind to these specs ...

Steve

Wow a potential 10% increase, that's awesome for 130 bucks. I'm curious to see how it works out for you once you get it running again.

Hell ya, that's a big, power to wallet-weight ratio!

What management are you going to run with the T3/T4?

There's a guy at my school running a T3/4 on his 2.5RS, and only made 176whp, and 160lb-ft.

I was pretty disappointed, so I hope you get some better figures out of it.

I should, at least i hope so. The one i'm getting flows a little more than an 18G and a little less than a 20G with spool up around 2500 rpm.

I'm ready to pay more than that, if I knew who can do same thing for a N/A engine.

Edit: I have a 94 Legacy 2.2L.

Have you called delta camshaft? They are located in Tacoma Washington. Good customer service. They probably would have something for n/a engines. I don't think the grinds are extremely vehicle specific. Kinda like HKS cams, they have a 626 and a 729 or something like that, i cant remember the numbers exactly but they use them for diff cars like supra, evo, wrx. I know cobb has some spicy cams for the 2.5 RS that matt monson has on his car.

Matt, if you read this, did you notice a difference when you put them in other than your dyno #'s?

Management is apexi s-afc II and apexi ITC (ignition timing controller) They've been laying in my room for a couple months now.

What engine was he using though Phil? His stock one?

Hardy - Yea, it was a stock EJ25, slapped a T3/T4 on it and running 8psi. I was disappointed .

Phil when he used to work at TurboXS, was at a wall of 390whp on his setup. No matter the tune, and TurboXS guys can TUNE, stuck. 2.5 block, 2.0L heads. Slapped a set of medium hot cams into the car and made 498whp. Then he blew the headgasket.

They've had a lot of guys here blow the engine by using 2.0L heads with a 2.5L sti block. Jon says they replace more engine swaps because of that. He said why you shouldnt use the wrx heads on a 2.5L sti motor but i dont remember the reason. The most successful appear to be the 2.5 liter RS heads on the block.
