my build: project gto [lots of pics]
-break into 11's [aiming for 117-122 trap]
-do it on a cheap budget, self built&tuned
-do it in street trim. as in drive it right off the street and race without changing anything.
lots of researching went into it. ill be doing everything myself, including tuning. ill be using a mustang dyno(and virtual dyno) for before and after results and backing it up at the track.
list of mods:
stock block/heads/cams/etc etc unopened 160kkm engine - 2bolt, cast crank, paper headgasket, 18spline
td04-15g's - unclipped in 9b housing from MTC
supra pump hotwired
emanage blue with timing harness
xtd stg4 clutch kit - 6puck unsprung
ngk bkr7e @ .028, oem wires
hks ssqv - open atms dump
lc1 wideband, gm 3bar map, apexi boost gauge
scanmaster3 + evoscan 2.9 to log
oem gutted cats + 3sx downpipe + test pipe + stock catback
devils own meth kit stg1 [630cc/min nozzle][pic1] [pic2] 630cc/min
maximal solid mounts
maximal stg2 tcase brace
ac/cruise/abs/aa/ecs/headshields/brackets/rear interior/bunch of other stuff delete.
9b@13psi dropping to 10.5psi by 6k
afr 10.1-3, 20deg timing
for comparison, stock evox did 190awhp, c63 amg did 310rwhp, stock 2010 gtr did 405awhp.
first round of dyno tuning
15g@15psi on jdm 9964 ecu, 94oct+meth
afr 10.8-10-10.3, 20deg by redline, base 5deg
21psi down to 15psi by redline (terrible turboxs mbc)
9966 usdm ecu, 3deg base, 94oct+meth
afr 11.5-9.9-10.2, max 15deg timing
track: 13.68@108, bogging the launch and knocking in every gear
20psi down to 18psi by redline + gm maf/t
9964 jdm ecu+gm maft+emb, 5deg base, 94pump+25%c16+meth
11.0 afr flat, max 20deg timing
track: 12.5@115, 1.9 60', 3400lb
got evoscan 2.8 up and running with OBDI. turns out you need a null modem cable to make it work. did a couple logs, nothing to report, everything looks good. have mmcd+palm as backup in the car.
installed lc1 wideband[pic]. placed it in the stock o2 spot and using its narrowband signal as well. logging on evoscan via com4.
sent out injectors to get cleaned.
testing of egrt input on ecu to use gm 3bar map[pic1] [pic2] [pic3] [pic4] [pic5] [pic6]. pin is there, circuitry is there, just wires are missing. tested limits, works. installed map and tested with evoscan, works. redid calculation in program to get accurate result. logging on evoscan now.
installed safc same time[pic1] [pic2]. zerod everything out. went for a drive to test, good to go.
replaced plugs with bkr6e, gapped at 35. replaced wires with oem. i really need a ypipe with coupler, i hate putting the stocker back on.
got injectors back, all flowed @90%.
installed them. have 2 spare.
current safc settings: L30%[-20@1,2,3,4,4.5,6,7]/H50%[same as low]
started car and its all good, o2's cycling, ~14/15 on the wideband sustained. havent had a chance to go for a drive yet.
tuned safc settings: L25%[-20 to 3k, -18 to 7k]/H40%[same as low]. ecu goes open loop right at 40%tps.
tested wot to 4k so far, starts around 12afr from 2500 and ends at 10.6afr so far. 0 knock with 10psi. started raining had to stop. waiting for sunny day to finish. once i get 14psi tuned ill throw in the supra pump and start again.
im tuning 500rpm at a time, so starting from 2k i go to 2.5k. then 2k to 3k, and so on. still waiting on my turbos to be made :mad:
Damn, you've been busy lately eh? Glad to see the build is going smoothly, hopefully I can start something similar soon.
I think I should delete abs and AWS too, useless
ADP still has my turbos, hopefully they will be ready by next week.
and looking for a pressure plate as well.
man living on this side of the border sucks for aftermarket parts
thanks for posting! looks fun! needs pics though!
we need more build threads on here.
btw i think youll be fine with the cast crank. its not *that* weak ... lots of people have put decent power through them.
i would also add an afpr to your list. will help you get more fuel if/when needed and will also help since you dont have timing control.
also... those are awesome 'before' numbers. what mods? with i/dp/ebc i was able to trap a couple mph faster but my et was nowhere close to a 13 flat!
set base timing to 5deg. i had it set at 4 before i had my meth [down from 10 stock jdm] to help with knock. ill be playing with this as i get deeper into tuning. from all ive read about td04 = timing>boost.
went out to do some tuning. only got a 2nd gear pull to redline [10.3 afr] then it started raining -_- i hate vancouver weather.
having some issues with the + battery terminal loosening up after hard pulls, gonna have to find something to remedy this.
highest power i know of on the cast was by mellon of 3si running a little over 500awhp before he spun a bearing. i think with a conservative tune ill be safe for a while.
im glad you mentioned afpr. i was deciding on the afpr as well. really wanted to keep this build as tight budget as possible. i came to conclusion that with 450cc i can still tune the idle even if the base pressure was 58psi (highest reported i found with hotwired supra). i can make my injectors 290cc even at that high of a base pressure through the afc. however, i will be running the stock wiring with my own relay system and "realmcoy"'s solution of dual resistors to the supras voltage transition problems. but if it does come down to it, i will get the honda fpr+supporting.
my before number mods are listed in the track times list thread. basically bpu with some weight reduction. the track was really well prepped. slipped the clutch good and even had 35psi in my tires to save my drivetrain, lift to shift etc. ive gone as slow as 14.5@103 spinning like mad through the 60'
i lied about the pictures, they will come once i start installing turbos lol
an update though, i took my turbo parts back from ADP for taking so long to make [3 months+] and ended up ordering 15g's from midwest turbo in cali. they should be here sometime next week. gonna be ordering turbo gaskets/trinkets & pressure plate next week then its time for surgery :D .
Would you be selling the 16T's then? I guess they still need a rebuild though..
yeah i gonna figure out what to do with them...
think of them as just the compressor and td04HL turbine, the rest of it is useless so it would have to be machined/rebuilt/etc. i dont know maybe $300+shipping for both turbos just so i get some money back that i put into them if anyone is interested?
so just a quick mini teaser update: i picked up my turbos from the post today, they look in great shape. im gonna open them up tomorrow to double check everything and will put up the pics ive been promising.
started tearing into the motor yesterday, took a bunch of pics and my camera decided to die on me lmao. when i get pics up its gonna be a huge dump.
[pic1] [pic2] [pic3] [video1] [pic4]
comparison with volvo 16t [pic5]
did a pressure test [pic1] [pic2]and found a huge leak at the rear oring and throttle body gasket. will be ordering those shortly. most of the piping is off, radiator is out, and ran out of time to sleep for work next day [today]. lots of pb blaster used.
gonna be replacing the main radiator fan with a a/c one that i still have from my parts car and wiring them both to come on together.
as the engine bay sits now [pic]
also bought a xtd stage 4 pressure plate that im going to be trying out after doing some research. im thinking of getting the turbos in and everything running properly first before tearing it back down for the clutch job to eliminate multiple sources of problems. also ordered a gto mr throttle cable to replace my ghetto modded cc delete one.
where did you get the mr throttle cable?
