Default 02 bug eye with 2.5l hybrid swap quarter mile

finally got the car all broken in and changed the oil. 5000 miles on it. heres my current setup, i built the engine in my garage, and its the first engine i have ever even pulled from a car.

2.5l sti stock block
2.0 wrx stock heads
stock wrx turbo
stock intake
invidia downpipe
3" catless turboback exhaust
catless uppipe
blitz BOV
blitz sbc, only running 10psi boost
untuned ( until i can afford an accessport and a tune )

according to the computer, since we didn't go to a track, it ran a 14.6 at 96mph untuned! i thought that was pretty decent myself, what kind of whp and wtq do numbers like that imply? the program also has a whp estimator but i didn't know what the aspect ratio was. can anyone help me out with that? it asks for wheel size, tire width, car weight, and aspect ratio? Also, if the car had a short ram intake, and a good tune, what kind of numbers would you experts expect? thanks.

this run was also while it was raining, so the tires spun a little in first gear. also was running on 92 pump gas.

p.s.- the 2.0 wrx block is for sale if anyone wants it, it has a spun bearing but the cyl walls don't look too bad.

but he is only running 10psi so it really isn't that bad.


i would guess somewhere near 130whp but that may be way off.

Why are you running a stock TDO4? That is really really small for the 2.5. Take advantage of the bigger displacement and throw a good size turbo on there. Your horsepower is going to be any were from 180-210....just my guess.

I have a 2.5L block on 2.0L heads plus some other stuff and a protune.

I make 226 hp / 258 tq to the wheels.

Not sure what the quarter mile is yet.

Meh, its not too bad I'm pushing 13 flat with the TD04 on a 2.5 . But I think money is a major concern of the OP, considering he did all the work himself and is saving for EM/Tuning (much props on doing your own work BTW).

...

flon3y do you have any pics of the in progress build? Also where did you get the 2.5 from? New? Used? I'm assuming its not from a wreck since you are using your old heads and turbo....

Also, how does the tuning with an AP work on a 2.5 with 2.0 heads? Obviously you cant use the OTS mapping, so you would need a protune. Why not just go ECUTEK?

i might have some pics of the build around somewhere i'd have to look and get back to you on that though. money is definitely a huge controlling factor in my situation. i got the block new from worldone performance here locally. i haven't really considered any other tuning options, what would be the advantage of ecutek over ap in my situation?

Don't go to EcuTeK, you are much better off getting a Tactrix cable and tuning with Enginuity (sp?). It will be much cheaper than an AP or EcuTeK and you can do all the tuning yourself or take it to someone who knows what they are doing. The Tactrix cable and a laptop is all you need, and providing you have a laptop, you'll be spending under $100.
