LST / LS-T Turbo B18A B18B setups

Originally Posted by blackeg you will have some pretty good traction issues if you are hitting full boost at like 3500 rpms. as it sits now, if i just go from like 20mph in 2nd gear and floor it, by 5k my tires are peeling very loudly, and i continue to sping w/o moving foward much. if im racing, i cant bang 2nd or 3rd really, and have to ease into full throttle or i will just spin and kinda slide sideways. this is on street tires by the way I can't agree with that. It's probably due to unlinear torque curves. The bigger the slope on the torque curve the greater the problem. I have actually solved peoples 250whp traction issue by making the boost transition torque smoother. A lot of people just run a standard retard and make sure in boost they are at or uner 12 AFR. This makes for sudden power at later RPM hence traction issues. I cured the problem by retarding the timing starting at 3 or 4PSI and keeping 12.5-13 AFR until 3-4 PSI. Just this eliminated most traction issues. Traction issues start with tires obviously, but can be help with smoother torque curves until peak torque is reached. I'm not saying this is your problem, but it can help a lot of people that say they have traction problems with under ~250whp in second gear on standard street tires (aka not DR's). under 250whp you should not have 2nd gear problems on standard street tires.

what was your timing at full boost? what is your dizzy timing at as well?
higher considering upping my lbs......

[adseguy]

at peak torque I'm at 13 degrees and 14 degrees at peak HP and the rest of the 16 PSI column. I actually made 300whp at 13 PSI and that would be perfect if I wasn't on stock pistons. The cylinder pressure at that PSI and timing are not good for the longetivity of any engine. Stock cylinders are the weak sause in my system so I have to work with that. Like I said cylinder pressures are what kill engines (aside from detonation). So unlike most Dumbass HT members think, you know the ones who immeditely say "OVER 9PSI IS DANG3ROUS!!1!!", running more boost is better for stock internals and will help me keep my 303whp and 260trq for a long time . On non stock internals or under 250whp I always tune for max power and then take a degree or 2 out to keep it safe.

[S@nt0s]

how long have you been running oyur car? daily drivin? that was on 91oct correct?

[Touge Tuning]

adseguy - i have a few questions for you but ill put that in pm. Your setup is really nice and your vid is one of the nicer ones ive seen around the net, shows you take pride in everything you do.

[King Tut33]

Great things in this post. I can't wait to have my parts assembled soon.

[JDMs1eeper]

I'm running an STR intake manifold on my current setup.

let your WG read from the brake booster and you shouldnt have no pressure drop problems.

Been boosted on "this" setup for 7 months now.

BTW, my car is deff. in the 11's and i dont have traction issues as long as i granny shift

[hybridsol]

303whp 260trq at 16PSI - many may say "why such high PSI?" and I answer "That's because I don't want my motor to blow on my stock internals " and if you don't understand why running less timing and more PSI is better, then search .

vid here > http://web.umr.edu/~amsrh7/car/adseguy's_turboteg.mpg

i was thinking of buying a 3 bar map sensor to increase the boost.....im currently running 9psi ( spiking at 10 psi ) and when i saw your thread about your turbo setup with a stock b18b and running it at 16 psi it made me want to up the boost...any tips on the 3 bar you can share...i haven't talk to my turner yet....he uses crome...just looking for some info from you..thanks

My car has been boosted for around 15k miles now and about 2k more on 300whp. Yes it's daily driven, but I don't hit all 16 PSI everyday. How you drive it is also a major factor in longetivity! I do hit redline once or twice everyday, but only at 12PSI (~240whp). When I have to race or show someone up though the wheel spinning 16PSI is switching on by my shift knob button. 93octane....yummy

you can run more then 10PSI on stock map sensor. I haven't personally done this before or tuned anyone's that had to, but people have gone up to 12PSI on them. What you do is tune the last column (not always the last because the ECU may read teh second to last for voltages reasons I don't want to get into...just check with datalogging) to be conservative so that at 12PSI it's ideal. So when it actually hits 10PSI it's a little rich and timing is a little too retarded, but once it hits 12PSI it's perfect...get it? . 3bar works with everything now a days. I even made a post on the Uberdata forums on how to re-scale the maps to be more accurate

my torque hits 200 at 4900rpms and sits flat on 200 until about 6300 where it slowly drops to like 190. at 3.45 psi im running 25.75*. i should try tinkering with it more one day. i should also get some real tires, not the discount kumho's. i wonder if the fact im running a gsr tranny has something to do with it too???...

My girlfriend's old setup was really simple..

99 B18B all stock
T3/T04B unknown wheels .48 exhaust
Rev Hard manifold
Tial 40mm wastegate
440cc injectors (maxxed out)
Hondata 4b then S100 or S200 (depending on if a customer needed the S100)
293whp 272tq @ 20psi for 2 years with a best pass of 11.8 @ 119mph on boost only on 93 octane


added a 50shot wet on C16 and changed nothing else and ran 11.6 @ 123

sold the motor to a guy who sprayed a 100 shot on it for 60months.


I built a friend's LS-T and it was much more impressive

JG pro head built in 96
JG1001 cams
stock B18B short block
rev hard mani
Tial 40mm
T3/To4b 50trim .48 exhaust
STR intake mani
DFI Gen 6

305@10psi
380@16psi
all on 93 octane.

Ive tuned lots of stock LS engines to 275-300whp most of which lasted a long time with some serious abuse.

Hmmm....alot of you guys are making good power on 10psi. I'm making 236. And I'm not seeing full boost till almost 6500. I have:

Very true

[Touge Tuning]

Do you guys think $850CDN is a good deal for a used SC50 and used TiAL 38mm wastegate (20K km's).

I am very impressed by the torque numbers all of you guys have put down, im really hoping i can get close to 270/280tq on the stock b18b1. I guess ill be able to put down some nice numbers too once its all said and done and i have 94 octane at the gas stations so im even luckier i guess?:D
