I've got a lot of build up on my head, as you can see in the picture below. I was running e-manage before, and i'll be running Vi-Pec this time, but is the build up just due to shitty tuning from e-manage? Also, what's the max hp someone has ran on stock b16 springs, retainers and cams? I was hoping for 325 WHP reliably. The car is not a DD, and is used only in the summer.

 

The build up looks some what normal, just running a little rich? shouldnt have a problem make 300+whp on stock head....

 

ya, that's what I was thinking also. I'm pretty sure e-manage is auto tuned very rich, so people don't blow their cars up. Would this carbon build up dissapear once I get the car re-tuned a lot better using vi-pec?

 

looks fine to me, meaby a bit rich. notice #3's ex valves look hotter than the rest? might just be the pic.

 

Well, I'm almost 100% sure that greddy's pre tuned e-manage system's are tuned very rich. Which makes sence, but can cause a lot of build up. Ya, they do look a little hotter. I did a compression test before I took the motor apart, and it was almost perfect. Could anyone tell me if this carbon build up will get better once the car is re-tuned using an actual good tuning software like Vi-Pec.

 

yes because you wont be running as rich...it looks fine to me to be honest throw her back on and get her back up and running

 

ive got all stock parts in my b16a2 and it dynod 329/224 SAE on 12 lbs. and its on a pretty conservative tune too!

 

all stock internals? did you do a headgasket and head studs upgrade, or no?

 

nope, stock studs, stock oe gasket yo.

 

damn. I was looking at only 315 whp until I get my springs, retainers and cams installed. Then go for 350 whp. Anyone tell me what tranny is in a 99 civic SiR? Also, does it have an LSD already in it?

 

should be an b16 s4c. and should be stamped if its got lsd, most honda trannys are. if you cant tell, you can jack it up and spin the wheels. should spin the same direction if it does.

i made 351 wheel uncorrected on it. it was a little cold out tho. 56*

 

Gotcha. Only thing I need to finally put the car back together is a bigger rad, and a new fan. Anyone have any suggestions as to where I could get both? Or should I just stick with the stock ones?

 

stock single core works fine. i would get a 10" or 12 "slim fan.

 

where could i get a nice fan then?

 

ummm, if you lived close to me i could sell you one for cheap i have like 3 lol. but just order one off ebay motors. should be good to go.

 

Ebay fans are alright? I don't usually buy car parts off ebay...

 

well ive had mine on for over a year now and it works fine for me. its up to you tho.

 

what type is it?

 

idk what brand. im sure any high speed slim fan off there will be fine. i bought the cheapest one and its doing fine. ha.

 

haha, alright thanks. Rarely get's about 30 C here, so I'm sure it will be fine. With a slimmer fan, i'm hoping I can fit a filter right on the turbo itself. Try and save some room.
