hey guys i have a turbo question for you turbo experts. I'm just recently pushing 10 lbs and @ WOT in 3rd gear in a higher RPM i would get like a back fire. Is this a miss fire cause by the incoming air blowing out the spark from the spark plugs?? What can i do to correct this? I got stock ignition and wires with NGK heat range 7 plugs gap @ .024. Any suggestions would help. thanks

 

I dont know much about tuning at all. I haven't learned all that yet, but im sure its got a very good tune. It was done by a very reputable tuner around the area, and his dyno is also known for reading slightly lower #'s compared to another local shop.
Final #'s the car put down were 212whp at ~9psi and i don't exactly remember but i think nearly 195wtq. Yes, i wish it would have made a little more power, but oh well. This is my first ever turbo car and the quickest car I've ever driven. So far its really fun, and puts a grin on my face every time i hit boost Im happy with it.

 

have you changed your cap and rotor? how old are these? that is where I would start.

 

so that is a miss fire right? The cap and rotor and probably a littler over a year old with no more than 10xxx miles on it.

 

i think that ur car is just running rich is it hesitating is the tach skipping when in 3r?

 

do you have a wideband in the car? whats are your a/f ratios in boost when its breaking up? if you have 10k on the cap and rotor its time to change them and start there. if that doent work gap the plugs down but sounds like its leaning out or loading up cause with a 24 thousands gap you shouldnt be experienceing sparak blowout with only 10 psi of boost

yeah Ahmed send me pics of the block

 

so on 12 to 15 lbs on my ls what is the proper gapping on my NGK irduim plugs

 

.24

 

My a/f is around 12-12.2 which is pretty nice. I'll replace the cap and rotor and let you guys know if it still acts up. thanks for the advice.

 

looks nice bro.

do you have any #'s yet? im interested. this is very similiar to what i want my build to be. main difference is you're sleeved and i was debating on just block guarding mine to save a little money.

any opinions on block guarding here?

 

or .024 if you want your car to run lol

 

yeah lol .024

 

I got the same problem but this occured in 2nd gear AFTER tune. I just put in a brand new cap and rotor before it got tuned though. 10psi of boost and got NGK plugs (NGK BKR7E) on there.

 

then its leaning out or breaking up or you got a weak coil

 

so my lsvtec spun a rod bearing and i dont have all the parts to finish my built b16 so i tossed in this stock 200k ls for now.

after 1 week melted the #3 piston so i tossed in another piston and gave all the cylinders new rings while i was in there.

heres what we are working with.

95 b18b1, 200k, fresh rings, fresh felpro hg haha
cable b16 trans LSD
act hdss 4puck
b20b cams (the 146hp, 146tq one) had em laying around so i put em in
cast mani
holset h1c 18.5cm2 hotside
the rest you can pretty much see in the pics

before the rebuild i ran it at the track on 10psi and melted the #3 piston at the top of 3rd gear and coasted the rest of the track and went 12.8@101 (90mph in the 1/8th) was street tuned by me on turboedit.

on the rebuild and now obd1 conversion (running free crome) im looking to get 11.99 on my 24.5's and about 13-15psi of boost.




i know my bumper is falling off, i removed the big bumper support and my makeshift brackets need fixing.

 

very nice man and hows that tranny boosted? do you blow threw gears ?

 

yes its pretty short. goes through the gears pretty fast. im pretty sure i hit my 7200rpm rev limitter in 5th the other day (~130mph) on 185 60 14s.

 

question for you guys. i just got back from the dyno i'm alittle disapointed. my goal was 400 and i didn't make it. only made 372 hp and 293 tq @20psi. was all on pump 93. my setup is sc44 turbo, 600hp precision ic, precision 880 injectors, revhard mani, 3 in dp open, open dump tube, cp 9:1 pistons, block guard, eagle rods, blox intake mani, crower valve springs, ferrea valves, stock cams, stock ignition, plugs were gapped at .28

the turbo is brand new and has been sitting in the closet. it seemed like it didn't want to wake up. my injectors also were not correct as he had to add more fuel because of the duty cycle. i will post a pick of the graph any idea, should i get an ignition put race gas in or get a bigger turbo?

 

here is pic of the dyno graph not the best pic sorry

 

i'd swap out those cams for something aftermarket.

 

Very clean DC for sure.

Between the cams and turbo i wouldnt expect any more out of it than what you got. thats great for an LS on pump gas especially with stock cams and believe me that car is going to be a rocketship.

Opting for a bigger cam right now i dont think you will see to much gains other than being able to rev a little higher and maybe a little more top end but without a beefier turbo its not worth the cams swap unless you plan on cranking thr tubo up another 6-8 psi and running race gas IMO. Then you will see some nice gains basically your running a 60 trim t3/t4 and your right in th eeffeciency range of that turbo. 25 would probably be max for effeciency then you start dropping off any higher in boost pressure. but a cam and some revs and race gas will pull some more power out of that turbo but you also have to consider its an LS engine with stock cams so its not as effecient so the numbers will be lower. with a good cam IE jg303's you would pick up some but dont expect a whole lot more out of that turbo. its rated 550 crank so getting close to 500whp out of it would be pushing the limits of the turbo and opting for somethign larger might be what your looking for

BUT again 370ish on the street is a rocketship. **** 260whp i was dusting z06 vettes in a full weight gsr and my 210lbs and a huge speakerbox lol also need to keep in mind your running a revhard cast log, any cast log is going to get restrictive when you start crankin boost. so there are a few factors playing a role here but i would be more than happy with what you have and keeping it reliable

 

Fellas here's my SET UP running with a Mustang GT supercharged!!! My EK is not yet at Full potential could hold 21psi..GOTTA LOVE THEM EBAY TURBO!!

Hey justin did you ever run your old head NA? My turbo kit is pretty much gone and my wife is going to drive my coupe so we can sell her 4 door. I may leave my engine setup and tune it NA haha. Probably autocross it on the weekends. I think it may still rip pretty good.
