Ke20 3Tc Weapon

Recommended Posts

I recently aquired a 74 KE20 to use as my primary track car while I finish a few other projects.

 

It has already been extensively modified and mod plated for everything which is the reason I bought this particular car.

 

The build specs as I bought it were:

 

3TC Bored and Stroked close to 2L

TRD cam, twin webers, fixed timing dizzy

T50 with trd close ratio gearset

RX2 with mazworks LSD, 4 wheel discs, hydraulic handbrake

6 Point cage, seam welding, buckets and harnesses

Rays 3pc meshies

Mod plated for all of the above in QLD in '95

 

The bloke I bought it off was a dodgey prick though, and despite my only condition on buying the car that it be a 'nothing to work on' deal, I've already had to do a fair bit of work.

 

The whole steering system was shagged, worn steering box, flogged bushes and dangerously sloppy tierods etc. Zipties instead of brake clips, leaking brake fittings, leaking coolant, exhaust had more weld than tube etc etc.

I replaced the whole steering setup with KE70 rack and pinion

Grafted the 70s firewall mount to the 20, standard 70 column mounted directly to the 20s dash.

It does sit too much to tye left by about 1 - 1.5"

Took it to proserpine and had my first crack at drifting. Had an awesome day, lots of fun throwing the death trap sideways!

The old girl has heaps of body roll, I havent had a chance to make some roll centre adjusters yet so the steering is out too.

The only dramas I had all day where a snapped accelerator cable, stretched clutch cable and the brake pedal pin came out.

 

My gopro battery died early in the day, well before i got a feel for the car and drifting, but I put a crude chop job together of some not entirely shit bits:

Superpro bushes all round just turned up along with new ball joints. Good time to measure up and machine up some roll centre adjusters.

Next big upgrade will be weld on coilover front, and thinking of removing all but a locating leaf in the rear and throwing some coilovers all round.

 

Not sure if anyones gone down that path on the arse end?

I bought the headers 2nd hand, apparently the manifold flange had been 'modified for clearance' for what I don't know. I chopped the outlet flange off and welded a V band on. I had to massage the floor pan for clearance. Modified my gbox xmember to allow a 2.5" pipe to pass through it. Trying to keep the exhaust tucked up high.

 

Also, my rolla is RHD so no steering shaft or box. But since obx are US market, that shouldnt be a problem.

 

And yeah the rolla is a fun little rig, will be better with good suspension

I replaced all the bushes in the rolla with Superpro poly bushes, grafted a TA22 rear swaybar, fixed some wiring and replaced the intake gasket and softmounts.

I made up a punch to modify the gasket to suit the ported head and match ported manifold. I collected all the pieces that were trimmed and it added up to the equivalent of half an intake port!

 

Big difference in handling, steering and power!

Getting some good angle and something resembling control
