ive built up my z6 head and block{y7} the z6 has a z6 camshaft and stock cam gear. and the y7 block has stock crank and pulley. i line both the cam up to tdc and crank to tdc. and im throwing codes cylinder position sensor and tdc sensor. ive replaced the ecu with p06 maps cuz i have no vtec yet. but it bogs out and runs like **** and doesnt idle very wells. it feels like it has 20hp tops and around 2000rpm it wants to die. so do i need an adjustable cam gear and how much do i retard or advance it? anyone that has done this before please let me know ive been trieing to get it to run for weeks.

bump x4 anyone??? no one has done this?

 

oh man, these obd2 blocks with obd1 heads rack my brain. give me a bit and i'll figure it out

 

okay I am assuming you have the following:
Z6 Head, Z6 camshaft, Z6 cam gear
Y7 Block, Y7 Crank Pulley


set your cam to TDC like this:



The z6 head/cam/dizzy is supposed to sync up with the p28/p06 maps at 16 degrees BTDC.

HOWEVER, the timing marks on the y7 (or any 96-00 D-series) pulley are at 12 degrees BTDC.

You can either bust out a protractor and make a mark 4degrees away from the timing mark on the y7 pulley (or 16 degrees away from TDC mark). Or use a dialback timing gun and dial in 16 and set IGNITION timing based off of the TDC mark on the crank pulley.

 

thanks that helped me and i think i know what i did wrong. i lined up the camshaft gear with the head. i ordered that back plastic thing a few days ago so ill line it up with that and it looks like the head and that plastic thing are probably a tooth off. which my car feels like it is a tooth off or so. thanks man. if this fixes my problem im sending u $5 paypal

 

and if you do that, i'm gonna send it to someone who helped me out

 

give me another 2 days and ill let u kno if it worked.

 

well i just got done and the thing starts and dies like 2 seconds later. soooo idk. fuckfuck
