why is my rb25det slow!?

[ANVIL]

so i finally got the swap completed and running, seems like everything is connected and fine but when I drive around it feels slow. the first time around the block was really slow. checked the ecu and it wasnt plugged in all the way. made a huge difference but still doesnt feel as fast as it should be. shouldnt an rb25det equipped s13 at least be able to run like low 14 1/4 mile times? my 240 feels like it wouldnt even run a 15 sec pass. what can i check to make sure its running correctly?

TIMING

ALSO.... IN BEFORE CHECK FOR BOOST LEAKS!!!

[ANVIL]

how do i adjust the timing?

[Fearsome_tea]

well if every thing is stock....use a timing gun and adjust your cam angle sensor. Assuming you do not have a boost leak.

omg 15's ouch, i have never ran a 14 or 15 in my daily driver. mid 13's everytime sounds like timing

[eh?]

Are your knock sensors hooked up?

lol because its a 25.

lol because its a 25.

last time i checked a stock 25 made more power than a rb20.

[midnightsliding]

made more power then a modified rb20.

Ouch 20 haters... boost leak ftl I'd guess, either that or you drive too many F1 vehicles...

[ANVIL]

im pretty sure its my timing. havent even checked it since the install. checked the fsm and im going to adjust it tonight or at least by this weekend.

[rotorimp]

Do you have a boost gage? any backfiring?

[ANVIL]

ok well i adjusted to fuel pressure... was at about 60! now its at about 37. I adjusted the timing but I think i went to the wrong mark. I went to the 4th mark which i think is 20 degrees....shouldnt it be the third mark, 15 degrees? well i drove it anyway and I did notice a difference but doesnt feel like its quite there yet. im starting to think I have a boost leak now. I still need to change the spark plugs. will running nothing after the downpipe affect how its boosting? my boost gauge hasnt gotten in yet so I dont know what im at.

oh goodness...

Download the 33 FSM... its stickied!!

[pawpaw18_00]

You will know if you have a boost leak even a little leak will cause the engine to surge and sputter a lot when boosting...so if it doesnt do that then look else where...for your problem...

[wawazat8402]

if youre running the actual downpipe you should be fine on that end. if youre running just the turbo elbow, i had problems just warm starting the engine to check my wiring like that. the o2 sensor gets hit with fresh air making it send in too much fuel.
