nice #'s, but why did they stop at 6200rpm when hp is still climbing?

isn't that sorta low for an fp green?

unless it's a low reading dyno..

Its a mustang dyno which is one of the lower reading dynos.

I still do not understand why people spend a great chunk of change pulling the motor, replacing it with something a lot better (not necessarily built) and then leave the WRX heads on without any modification. Just stupid IMO.

He bought the car with the motor in it. It just got past the break-in so he got an fpgreen and suspension to autocross.

The WRX are not that bad in comparison to STi heads IIRC. They still flow fine, they just run out of juice in higher HP configurations. However, you can still port them out to make them flow just as much as STi heads. Just do a search for the crazy PR guys who run 10's with the WRX heads.

The car has a hallman pro boost controller on it and that controller uses 2 different springs a soft and a hard, soft will only let you fine tune boost only up to 5lbs over stock and that is the spring I have. When we find the hard spring then I can turn the boost up and we can shoot for the #'s that the engine can make.

those are good numbers on a mustang dyno

Is that with SAE compensations?

nice numbers,

what are you doing for a tranny tho?

The tranny is the 5mt sti ra gearset!

Headwork is not cheap. Not everyone can just drop ****loads of money at one time. People have to work with what they got. I hear that kind of stuff all the time on here. "Why not go rotated" and all that..uhh because it's expensive as hell.

I would like to see someone drop STi cams in WRX heads and test them against STi heads -just for comparison. The cams aren't all that different except that the STi's have a bit more lift from what I gathered (AVCS aside). I think it would be interesting.....
(sorry to go OT, but post 18 & 19 actually covers it at this thread (http://forums.nasioc.com/forums/showthread.php?t=1219386))


So, how does it feel on the street Ironman? looks good

I will not detail how much I was forced to spend due to someone's mistake, because of current legal action.

But if you add it all up, a grand or so for cams, springs, retainers, all that ****, are you telling me it's not worth it? You paid, what, like 2.5-3k(maybe more?) for a Crawford SB, and you can't spend another thousand, with maybe a few more hours for labor (the motor is already all apart)? I'm not saying spend $1500 to port out the heads and then do all that work. If you're telling me the money wasn't there to do something like that, then that's plain retarded. And if you price it out from the start, going rotated is pretty much equal if not cheap in some cases than an FP or Deadbolt "stage 4" setup. I can do the math if you can't handle it. If you think going rotated is as expensive as hell, maybe you need to move on to something else, because it's really not.

Waaah dude. I've been there three times over, I can tell you about expense. Move on? You must me living out of mommy's basement if you think it's that easy. No one said it wasn't a worthy move, it's just not always viable. That's all I'm saying. Not everyone is going to pull out the plastic because some over opinionated OT'er told them so. Right now if I wanted to buy an FP Red, or an SZ55, or the like, all I would need to do is lay down a "measly" 1300-1600 (depending on new or used, or maybe even score something a little better) and at the worst only have to buy an inlet... and that's it... if I wanted to go rotated, I would have to spend another 2 grand. And you think I can't handle the math? It's not the A=B equation that everyone makes it out to be...ie it's not the same. If 2 grand on top of 2 grand is no big deal, then maybe I need to move back home...... When you pay your own bills you'll know what I mean. Go big or go home sounds macho, but it doesn't always hold up in the real world.
Once again, not saying it's a bad idea, just not worthy of the trust fund kid scrutinization that people tend to have on here.

sorry for screwing up your thread Ironmansixx

Its cool! you didn't screw anything up. To set the record straight, I bought the car with the 2.5 swap already done. The cams and heads are in the future plans for the car! I didnt got rotated cause I daily drive this car and use it for autocross! so the money spent on a COMPLETE new suspension(swaybars and endlinks front and rear, coilovers, new bushings all around and a set of tires for autocross!) couldn't be spent on huge engine mods. the green provides PLENTY of kick in the pants for me It spools great and pulls all the way to redline. It was tuned for Autocross I dont want a DYNO queen but something thats useable and reliable. Plus a wife and a 2yr old, they come before the car!

Glad they are in the future plans for the car, and that family comes first! What are you looking at doing to the heads besides cams?

I PM'd TyranosaurusWRX just to keep it out of this thread, just so you know. I don't want to make a mess of your thread either.

Its all good man no worries!!:) I think i want to stay the hybrid route so port and polish just to maximize what the wrx heads can do! I havent really looked into anything as of yet so I havent weighed all my options either!

Ounce you get passed 400whp....you might want to think about a set of ppg's or a 6-speed. Nothing against the RA's, I have a set myself. But they are only supposed to be able to support 350TQ according to specs. DOnt let it stop you though, There are guys with way more than that and they are doing fine. Just my .02

+1..someone on NASIOC with some sense..go figure.

The RA's should handle the autocross stuff just fine.. drag racing is another story but then again it is all about how you launch. Very nice car and good luck at the autocross. I might have missed it but what Swaybar setup did you go with? Front and rear? Thanks!

I still do not understand why people spend a great chunk of change pulling the motor, replacing it with something a lot better (not necessarily built) and then leave the WRX heads on without any modification. Just stupid IMO. Because an EJ257 short-block upgrade is roughly 2k in parts (stock block); but to upgrade the heads with new cams and valvetrain components will cost roughly $1,500 bucks not to mention the need for the heads to go to the machine shop which would tack another $500 bucks on there. So when it’s all said and done, the heads cost as much as the underlying motor to upgrade. And for what, another 30~40 whp? The dollar to hp ratio is not worth it to upgrade 2.0l heads IMHO. Might as well replace them if big-power is the plan for your motor...

A 2.5l hybrid motor (with stock 2.0l heads) is such a great upgrade over the puny original 2.0l. Granted the whp increase isn’t that dramatic, but the new found torque available is well worth the upgrade.

Thanks, I went all Whiteline 22mm adj front, 24mm adj rear, front spherical endlinks, rear solid links, megan racing coilovers, and all new whiteline bushings.

Sorry to hijack, but would V7 heads work for better flow?

yes read up on it, also allows for higher redline if your bottom end can spin that fast. not sure if an stock ej205 can rev to 8k, or if an sti 2.5L shortblock can rev to 8,000 either with its higher piston speed however a properly built ej205 can, and certainly an sti 2.0l block

Thanks! Looks like that's one more thing to add for down the road then. :lol:

Not to hijack but whats with that a/f - it looks very erratic - is 11.4 really your richest point ?

It's 11.0 at the richest, 14.6 at the leanest, with an average of 11.6.
