hey guys i have looked everyone online for the information im looking for so here it is......

i just recently decided to rebuild my vvti 99 sc300 but since there were rumor or speculation that the vvti bottom block is weak i decide to change the bottom end to the non-vvti block.

i ran into few problem: (but i was able to fix!!)
1. As there was no oil line fromt he block to the vvti head so i found a way to bypass that..
2. there is no electronic crank sensor on the block so i took mine off the vvti engine and added it the non-vvti block

the real problem comes in where i put the engine together with a thicker gasket for the turbo i have but the problem is that the engine wont start.

i have aligned the timing correctly so its not the timing i aligned the the dots mark on the cams with the first tick on the crank. i have tested my ecu with other car and my ecu works fine. i am getting fuel to the injectors and i am getting spark. also the igf is working, everything i could think of has been looked twice and then 5 more times.

NOTE: this is a vvti 2JZGE head with a non vvti 2JZGE block from a 92-96 sc300. both head and block have been fully rebuild.

the problem is that injector 2 and 5 are spraying but it gets cut off while the other are still spraying. the other thing is that injector 1 and 6 soark only once while the others are conitniously sparking!!!! what the hell can the problem be? do i have some wires backwards? or does the bottom GE block just not work with the vvti head?



HELP BEEN STUCK ON THIS FOR MONTHS NOW!!!!!

my recommendation is to take it to Kean over at boost logic and have them fix it for you, or to any reputable shop.

What modifications have been made to the harness?

did you install the timing gear behind the crank pulley?

i want to avoid taking it to a shop adter much time and money spent. no wire job has been done and the car did run before rebuilt.

is it that the non-vvti block are not compatible with the vvti head?

next thing to do is to order a new harness and see if it fixes it someone told me it could be bad ground but i grounded everything and its not timing or else there would be no sparks at all

I am having the same problem. did you find out what the problem was? if not double check your distributor and make sure the mark on the gear matches up with the mark on the shat.

I think it's timing issue, hope you didn't bent the valve, do a compression Test.
check the fuel, and spark?

I finally got the car started today, turns out I didn't have one of the ground wires connected.
