Seriously, if you feel that you are not up to the task. Why not just pay someone to set the timing for you? I mean you have to know someone that is capable of doing this for you. Even with a shop doin this it would not cost you over a 100.00 bucks. Just seems totally insane to sell you whole swap just because you timing is off :facepalm: :wtf2:

man, dont give up.. it took me a few months to diagnose what was wrong with my rb but once i got it running i loved it.. i was in the same boat as u, wanted to sell the b**** but when u drove it for the first time, its was all worth it..

n when u said the timing are u talking about the cas or replacing the belt.. u can seriously mess something up setting the timing aligning the cams,crank,ect.. but the cas, u cant really go wrong.. read the fsm slowly so u can understand it..

Oh, adjusting the CAS is just like rotating a distributor.. Lightly losen the 3 bolts holding it in place. Then rotate it while the car is running and listen for it to run better/worse. Obviously put it where it sounds better and tighten... If you didn't mess with the belt, hopefully who put it on would have known what they were doing.

Does the engine sound rough when running, you may have a spark or fuel deliver issue instead of a timing issue.

Your coils may not be firing properly. Its common. Take all the coil packs off. Next take the boots off and the springs out of the contact points. Next take a cheap $10 dremel from harbor freight and dremel the contact point on the inside of the back and bring it to a nice shine. Replace or use electronics cleaner on the springs. Reassemble, and use electrical take on the boots; wrap them up!!

Now hook everything back up. Start the car, listen for misfire. Unplug one coil pack at a time, listen to see if condition worsens or stays the same. If the condition stays the same, you may need to replace that pack. To confirm switch one pack that made the condition worsen when unplugged with that pack. Also, take your igniter to have it tested. I would recommend a buick skylark coilpack conversion and a z32 igniter swap. Fixed all of my hesitation issues when I first installed my rb20 and its really simple to do.

wastegate is not open if its building boost. check the placment of your boost gauge line, if its before the throttle body then you wont see vac till the throttle is opened. What do you meen the turbo is popping?

like it sounds like if its popping out air and when i put my hand over the maf i feel as though something is pushing against my hand everytime i it pops so i dunno wth to do next....and should the car be building boost while it not rolling??? or what and i when i plug in my maf the car revs really high them shuts off dunno if i solve those things i can finally take my car out for a small run...my boost guages is coming from the last nipple on my intake...

pooping? u sure aint surging... if ur building boost n let off n u feel the turbo pushing air out of the maf instead of goin towards the exhaust its not good.. it making the turbo spin backwards, u need to loosen up ur bov some.. as far as vac, it should make vac weather u got a leak somewhere or not.. try another gauge but dont run it inside the cabin.. put it somewhere on the intake on the motor n look at it to see any difference ..

your reading boost from before the throttle. when its closed the boost gauge will have nothing to read. find a source after the throttle body(on the intake mani itself not the intercooler piping) to read from. I am almost willing to bet money on that.

you say when you plug the maff in it revs up? sounds like you need to go through and adjust all your sensors and check for boost and vac leaks. get a timing light and set the timing per the fsm. make sure all that is done and not the problem.

There should be a nipple on the rear of the intake mani which is for the boost gauge.
