Battery now wired in. Intake pipe made, comes straight out of turbo to the afm..
used original intake pipe and drastically shortened it to basically a single bend with
barbs on each end. Late 2tgeu thermostat outlet fitted with ta61 2tgeu top radiator
hose which points straight to the radiator instead of towards the battery. Some ta61
2tgeu afm plug wiring used as an extension wire to the relocated afm. Cam cover oil
breather pipe spun 180' and a little K&N fitted for now... this will theoretically
suck in air too which will bypass the afm and lean the a/f mix.. can cause afm to shut off
under idle and also turn fuel pump off. (same applies for some non blumb back bov's)
the pipe seems glued in (loctite?) but will spin or come out with reasonable
force. Dummied up the hilux 4pots on jzx81 disks... they poke out past the hub
so wheel clearance not lookin good.. only the 5 spoke wheels i have will fit. hmm
Entry for the '4 and rotor Nats' sent in!! joining the club-k club entry to the show
day and enter drags too :) got lots to do over the holidays!
21.11.05
Mods- started to mount battery in l/rear seat well and intake pipe mods to move afm to l/h
side. GTI-R intercooler end tank has been swapped 180', next is piping for it.
Bought some LN61 hilux 4pot calipers (heavy) to play with... if easy enough to do,
then may fit them to the jzx81 disks and ma45 struts. pretty heavy setup!
04.11.05
Another run down the strip. season opener for the nightspeed dragwars and absolutely
huge turnout! ran consistant 14.7 with a best of 14.61@ 152.5 on the last run after
letting tyres down a bit. tramp off the line becoming more evident. time to
replace the std rear shocks me thinks
30.10.05
Entered GM Drag day with club-k (see gallery for pics/vids). hoped to at least
crack a 14sec 1/4 for the first time.. got a best of 14.59 @ 153.8km/h.
stoked! most improvement came from the 4 puck clutch and the BOV probably helped
some too. engine mods at this stage are 2.5" exhaust, pod filter and a bov.
3tgte is otherwise std with 185k on the clock.
23.10.05
Finally fitted new 4 puck clutch plate and replaced the w55. Checked boost at full
rev and found to creep to 0.9bar! needs larger wastegate! have now fitted a
vr4 BOV plumb back styles to help stop any compressor surge for now.
09.10.05
some pics :)
26.09.05
dont like the idea of huge front track hmmm. disk conversion only possibly?
had another hell mish to get a wof. cut more rust out, this time the
major being the l/h towhook. new shock finally installed in the left strut.
installed new steering rack grommets (thanks Quintin). changed to T series open diff
etc. Entered Pukekohe open day on friday 23.09.05 for some drift practice with Tup
and Alex. 13 drifters in total and managed to get 4x 15min runs. Ah fun at
last!
15.07.05
bite the bullet time.. want to finalise the suspension and driveline so can finally get a
cert for this thing. i have bought jzx81 n/a markII 11" vented disk
struts. The advantages: bigger vented brakes, short steering arms for heaps of
lock, added castor, 5x114.3 or mod to keep 4x114.3 stud. Downside: is r'n'd required
to setup correct suspension geometry, wider hub meaning different offset front
wheels, extra track and maybe requiring flares.
The struts have a 5x114.3 stud pattern but has a flanged hub which can be redrilled 4
stud. The disk sits on top of the hub rather than bolt under so easier to replace if
warped.. and the steering arms are offset for added castor and are same lenght as ae86 p/s
arms (which im currently running). Next objective is to try set these up to handle
like a dream in the ke70, if not then bye bye new struts. In std form they run
a fwd offset wheel, the strut tube/stub angle (whats that called? steering axis
inclination maybe?) is around 11deg compared to about 8.5deg on te71 struts.. so
looks like i'll be needing longer lower arms and camber plates just to get these suckers
sitting in the right spot. Cressida arms are longer and vary in length depending on
model so will have to investigate that, but *X81 have a larger inner bush on the lower arm
so dont easily bolt in to corolla's. boy am i going to have a wide front
track! also since the hubs are alot wider the fwd offset rims are needed for the
sake of bump steer. also due to the larger disks i can only run a minimum 15"
wheel which i do anyway. The coilovers and shocks i have already will still fit
these struts too so its play time. if this goes ahead flares probly next on the list
heh.
29.05.05
wow what a busy week. filled a few small holes then scotched/sanded the
70. replaced doors, fixed starter motor (found the starter solenoid plug snapped
off). previously kept having starting probs on the 3tgt coz of this and had to hold
ign key on for a number of seconds before anything happened. Had issues with tail
light wiring which looks to have been previously replaced with aluminium wire?!! which
often snaps off. The spare 3tgte finally finished assembling on wedn 25.05.05, sat
the engine in the engine bay thurs night, painted car on friday night. hooked up the
3tgt during saturday, cranked it over at 4.30pm which started first pop after checking oil
pressure ok :) spent all saturday night/sunday morning putting the car back
together including swapping door winder and windows over to the new ones. Test drove
it to the track... turned up to d1nz drift school just in time. the new 3tgte runs
noticeably better. the turbo hardly smokes, the compression is higher at 125-128psi
compared to 115-117psi. dizzy vaccuum advance/retard diaphragm spat the dummy so
only mechanical advance. eek. but happy as with its performance (especially
from a pick-a-part motor). next step get a wof ha ha, then suspension improvements
in time for d1nz round4 since it handles like crap (currently no camber and understeer
inducing locker).
oh yay some pics :) first 3 show engine that came out.. grubby under intake due to
water pipe leak just below chain tensioner and blowing up oil filters. 3tgte on the
stand is spare one getting prepped to be put in.
30.03.05
Decided to reuse old water pump for a short time since so much corrosion is still inside
engine.. will do a couple of water (chemical) flushes to try clean most of it out then fit
new water pump. Copied new water pump gasket with gasket paper and installed old
water pump. gooed up cam cover 'half moons' as they weren't rubber anymore, kinda
turned hard plastic and have shrunk in size. Entry to d1nz declined due to 70
entrants and only 45places to fill, DOH!
29.03.05
Have pulled the 3tgte frost plugs out. found a solid wall of rust behind #4 plug,
dug it all out with a screwdriver, gave the water galleries a blow out with compressed
air... makes big mess it does! curses to previous owner for not using antifreeze!
fitted new 35mm brass frost plugs. scraped inlet/exhaust gasket surfaces
flat, removed thermostat manifold (water pipes majorly rusted). removed water pump,
shaft wobbly and impeller corroded.
28.03.05
Still blowing filter seal out. tried a genuine toyota (Denso) filter and yet to pop
a seal. a new one costs $20 retail so they more expensive but if they bandaid the
oil pressure problem then its worth it! well in the mean time I'm swapping in
a spare 3tgte bought from 'pick-a-part' last year and hoping it'll run. need to get
something running for d1nz in couple weeks. With 186k on the spare engine and major
water line corrosion, I knew it would take a bit of work to get it prepped for use... but
it's the hidden things that have become a problem. once mounted on the engine stand,
pulled off the CT20 turbo and had a go at stripping the corroded water cooling flanges off
the centre casing. it looks like the water pipes entering the turbo have rusted
through (rusted completely off actually) and sprayed water over the hot turbo. the whole
housing and turbine housing clamp have some pretty bad corrosion.. so gave it a good
soaking in CRC and put it aside. stripped off engine external bits so the block was
accessible. took the engine outside and gave it a degrease and water blast.
found two frost plugs with corroded holes in em. Drained oil then pulled sump
off. rotated engine upside down. checked bottom end bearings for excessive
play. pulled oil pump rotor and body out for inspection along with the pressure
relief valve. put sump back on with new gasket. whilst upside down gave spark
plug valleys a good clean so dirt wouldn't fall into the holes. Pulled cam cover off
and gave a light blow with compressed air to remove some of the caked on (and flaky) oil
deposits. this engine had obviously not been maintained. cam cover gasket is new tho
so looks like last owner made an attempt to fix oil leaks heh heh. turned engine
onto side. pulled plugs out, some were quite tight due to gunk around the
threads. the engine had water sitting in the valley for some time so looks like it'd
made it down the spark plug threads. cleaned threads up too then new Denso
W20EXR-U11 plugs fitted. (from Toyota). checked chain tensioner and had a good
laugh.. never been adjusted at all so there's a good 15mm play in the chain and
witness marks on the underside of cam cover (chain scrapes it when too loose).
pulled tensioner out for an overhaul. O-ring was square and the corrugated rubber thread
cover was so hard it crumbled. found the piston to be jammed up with so much caked
oil it didn't move so the tensioner never would have worked anyways. cleaned it all
up, replaced 10x2.5mm viton o-ring and reassembled. pulled dizzy cap off for a
look... both the graphite pins jammed in the cap, rotor split down the side,
mechanical advance jammed solid, vacuum advance diaphragm got a hole in it so dizzy pretty
much useless. next is to pull 3tgte out of ke70 and use the working parts off that
to get the spare engine running. Ordered new 9" 5puck ceramic sprung centre
clutch plate in the hope it'll keep a grip compared to the std full face organic
plate. will be using the std 7.8?kg 3tgt flywheel for now to see how much wear this
5puck plate will cause. have found jdm cressida gx61 1g-eu manual engine have the
same flywheel so no shortage of std flywheels. Cressida gx71 1g-eu flywheel has a
little extra meat on it and weigh 9kg but still interchangeable with the 3tgte.
22.03.05
took oil pressure relief valve out but seems to work fine. pump rotor pitted and
scoring the rotating parts.. not sure on cause of overpressure prob?? have tried a
Fram brand filter and continues to blow the seal out. this only happens within a few
mins from starting on cold engine. had two alternators die within one week :(
d1nz round2 in a few weeks... time for another engine change and get an lsd
installed. 3tgte timing chain rattling and tensioner adjusted all the way in.
compression seems consistent with #1 125psi, #2 117, #3 117, #4 120. turbo smokes
and chews through the oil. bottom end not quite knocking but noisy... um
yeah, rebuild time!
01.01.05
have been driving the ke70 daily since it came back on the road. in last couple days
have had a major problem with a bursting oil filter. luckily nothing was
damaged. first the oil filter seal got spat out the side on a cold start up and
pissed oil through the engine bay and floor, cleaned up and refitted seal then drove 20k
home. next morning went for a drive... got as far as 800m or so and boosted out of a
corner and 'poof' a nice oil slick trailing me. had a closer inspection which showed
the filter had split at the seams and is noticeably ballooned. oil filter change is
overdue, tho this should not happen if the oil pump pressure relief valve was working as
it should. yet to investigate actual cause. have now got ke26 back on the road
for daily duties.
