The car is running!

I replaced an old DTA P8Pro ECU with a Link G4 Xtreme. It took a month to figure out the correct ignition/trigger sensors setting. Now engine runs fine with a genuine Nissan crank sensor.

Test drive has done. Priority is chassis modification not the engine. I felt some difficulty in clutch pedal control because of Tilton clutch and lightweight flywheel. Next, the brake pedal w/o booster feels like pressing the floor. I am realized that I do not necessary to feel the brake pedal stroke during braking, it is better to try to press the seatback with my hip.

Then wide-opened the throttle several times. Boost was lost because the silicone hose popped out. I liked the rear multilink with the GT-R LSD diff.

 

Exterior is sleeper but the fuel pumps are too loud to be sleeper. I am already hacked the Toyota fuel pump controller pinouts. Link ECU has several flexible PWM AUX outputs so it can send the signal to the controllers.

Isolating the fuel plumping with cabin is also required in highway use in Japan. If not, the car does not pass the inspection. Metal work has finished.

High caster adapters, tension/compression rods and LCAs were fitted.

A taxi got tail ended by me:p I pressed both brake and gas pedals. So pedal plate of the gas was relocated by an inch toward the right.

Two good news. MXL dash logger finally shows the engine parameters again. I figured out a wiring mistake in RS232C TX /RX connection between MXL and Link G4 ECU. Also I found current bridge in vehicle speed pulse wiring.

Front under panel, made by 1/2" plywood. Engine oil keeps leaking from the oil pump.post-106-019001800 1304262367_thumb.jpg

 

My car is usually as slow as stock 260z because I rarely find the positive boost in the pressure gauge. Finally I found something hidden in the inlet side of intercooler.post-106-033208400 1304262390_thumb.jpg

 

A plastic bag. I put it in the piping during maintenance.post-106-036468100 1304262404_thumb.jpg

Haha as long as it didn't harm anything that's the best fix ever! Removed plastic bag and problem solved :D usually the problem turns into a much bigger pain then that.

I made critical mistakes on this engine. Exhaust cam was dialed completely wrong timing and tried to start it until the engine oil was saturated with gas, 30-minuntes-idling without the water pump pulley belt, oil filter plumping was the reversal direction, etc. I am very lucky man because just only a problem, oil leak from oil pump or the oil gallery plug on front side of the block.

 

BTW, a temporary grill cover was made from aluminium sheet. I'll test this if cooling capacity is efficient.

Kazu, I think i`m going to try your grill setup, and just do a little modification on it. Thanks for the idea on the grill.

 

No problem. It was easier to make than I thought.

 

I went to drive it. Finally it runs under full boost.

I saw the video below and decided to remove my front ZG flares upward quite a bit.

 

Previous position.

removed all but a rear end rivet and rotate the flare upward.

After cutting the metal fender, wheel can be relocated out by extending the LCA.

Gap at the front end was filled with pieces of flare.post-106-058932200 1305293518_thumb.jpg

 

Pic clearly tells why I had to cut metal fender. The 17" tire is as high as the stock fender edge.

Because of the floor mount pedals, I place the seat at rearmost position with extended steering column and bent shift lever. I hate the arc of the shift knob because the motion center is still in the trans.

Fixed the problem with an old stock of short shift kit for BMW.

Now the shift lever pivot is in the pocket of choke linkage. Ergonomically improved.

I am going to put dry sump system. Starting materials are L28 ARE pan and genuine RB26 pan. But I am not sure such shallow oil pan is necessary. LS7 has regular shape of oil pan :confused:
