My KE10 is very cute and seeing some of the other cars in this thread area, I thought I�d add it too. My fianc� Darren and I have done most of the work. The car came out of the factory with like 16kw @ wheels and now has 156kw @ wheels.
This is a retro pic taken by my friend for Zoom (It is the only good shot I have from the front in its current form)
This car was pretty much a bare shell / no interior, trims, etc but with a 55kw @ wheels garden blo thru set up with:
Stock 4K engine (1300cc)
petite Garrett T2 turbo
Charade GTti intercooler
I bought it in �00 and we put on a Garrett T25 (.48 exhaust) and a Supra intercooler. But I cracked a ring land @ 16psi racing Adelaide�s fastest ET Pulsar. Then I got a 1500cc K motor.
The original 4K head was prepared by a mate. C/R was dropped to 7.43:1 c/r (2 extremities of 5k dished piston / 4k head chamber area). Standard intake valves still reside inside to this day, but the exhaust valves have been substituted for larger items to improve flow.
I had to make my own pushrods. I joined 5K bottoms to 4K tops using cut down bolts inside to thread them together and nuts to lock the adjustment and a weld dag to stop them coming loose � funny as, but they lasted 1000km and did some 8000rpm pulls before a few unwound themselfs! New bottom end:
Shot peened rods
Shot Peened crank
Precision Hypertech pistons
Overbore
Crow heavy duty valve springs.
Double row timing chain
Repco special $95 cam grind
I assembled the new motor myself and put the car back together again under the guidance of a mate with a workshop. The new 5K blow-thru set up performed fine up to about 12psi, but the carby cracked in half and had to be replaced with a new DGV! The power-band was between 4500 � 8200rpm. No power was officially recorded as but a �gestimate� was 100 / 110kw @ the wheels. Carby sealing problems began to surface continually and tuning was difficult.
I wanted to run 20psi so I had to find an alternative. So next came:
4K-injection EFI manifold
13b series 4 n/a injectors
VL turbo throttle body
Microtech LT8
320hp (.64 exhaust) T28
Back at the dyno, power peaked at 115kw @ the wheels on 20psi � but the dyno cell was 42�C. The intercooler was struggling with a 6psi pressure drop across the core.
I hand painted the gauges to match the Autometer tacho
The next things were added:
Custom plenum / shorter runners
Custom FMIC
HKS2530
FMIC fitment
HKS2530 before fitment
The result was an increase of peak power but a huge lift in mid range power and torque and full boost delivered 700rpm earlier at 3800rpm. Peak power / torque is made at 6200rpm and power was 140kw @ the wheels. I had the interior and wheels done and call the theme �minta race�.
Everything just fits! The stock exhaust manifold will be replaced soon.
Most gains came from the �cooler, however the HKS 2530 above 16psi is not making expected power/ torque on the 1.5L. Recently, a custom grind cam, bigger exhaust valves and Manley home-made pushrods have increased power to 156kw @ the wheels on 23psi. The little wheels start lifting off the rollers at 100mph!
The diff has been locked and it has done a 13.3 @ 108mph with a Corolla 5 speed - but it wouldn�t go into 4th and had a badly leaking exhaust pipe. (Darren drove that time because the Adelaide Nationals is the only day of the year I wear a skirt and he got it ready for that meet anyway)
At Adelaide 4, 6 & Rota Nats, �05� note new authentic KE10 Japanese fender mirrors
There�s a huge amount of guess work involved with expected performance and component durability. Worked naturally aspirated Club Car 4K�s can only provide limited info, and then those guys get a bit �secretive� and don�t want to talk to a girl, haha!
(I also have SLO 069 numberplates for it too now). It gives the guys a bit of a giggle with it's double meaning.
