Mine has two. wires. looks same as the chts thats currently there. its not the sender so it must be the one.

I just purchsed a water temp sensor for my 280zx turbo. Im looking for a CHTS but the local auto parts store reffered to it as a coolant temp sensor and said they were the same. They look the same to me but are they really? Thanks Rick

This is probably why the cars running like ****. Im gonna wire it up normally and check the sensor. Thanks.

Heres a pic. Is this normal for the L28ET turbo?

I have a 78 280z With an 83 L28ET swap for starters. I noticed that on the wiring harness just before the CHTS their is a resistor on one of the wires. Should there be a resistor in line with the CHTS? Ill post pics soon. Thanks Rick

On the 20. Like so..

THanks. My motor/distributor is an 83 but the coumputer and AFM are from an 81. Does that confuse things? Ok so I set the timing gun to zero and checked the timing at the crank its at the 20 on the timing guide. So thats 20deg BTDC correct?

NewZed, not being smart, just sayin. It seems as YOUR the one being smart in some of your replies. Im no hater or smartass. Truce? Ill have to check the FSM to set ther right fuel pressure since its wrong. Thanks. Rick

NEWZED, It has a manual boost controller to raise boost. Pretty simple actually. I have one in my CRX. Turn a knob and get more boost. Never heard of one? Google Turbosmart MBC. I'd have to go by the shop to get the dyno results, I may or I may not. Doesnt matter. Timing was off and that needs to be set, bring it back to the dyno and see what the results are. Fuel pressure is 30 psi so its correct. Im thinking the oil pump was installed incorrectly as well which would explain why timing could not be set correctly. Ive got 2 different shops working on the car so things can get confusing. Since I got the car back both shops have been in contact with eachother so we can get things right. Not worried. Thanks for all the replies. Keep ya posted. Rick

The shop that did the swap deals with z cars exclusivley, mainly old z cars. As for my tuner hes been tuning cars for decades and tuned my other car (Honda CRX, SOHC 1.6 11 lbs 235whp). He knows his ****. Hes not very familiar with Z cars but took a look and figured out the AFM and made the mix leaner in minutes. I trust him entirely. As for non stock parts an aftermarket FPR was added, thats it. It appears that the AFM was tampered with prior to the swap as one of the glue blobs were broken. I figured I would run it on the dyno to see if the afr was good and check the timing as well under load. Everything was off. Now its a matter of trying to fix things starting with the timing. What other way is there to alter AFR on these cars? I thought the AFM was the only way?

Thanks. Gonna take the car back to the local Datsun shop and have them alter timing.

There was no room left to adjust the timing at the the distributor. I believe thats what he said. He was looking to get 18-20 deg but could not get it by adjusting the dizzy. He was talking about modifiying the disk in the dizzy that has the little whole drilled in it to get the desired timing. Anyhow.. So I called the shop that did the swap (differnt guy than tuner) and they said they would put the timing back to stock. They also said not to bother modifiying the distributor disk as it would make matters worse and that they had the ability to do timing correctly. Maybe its off a tooth somewhere? Dunno. Im gonna get them to do that and then bring it back to the dyno and see how we look. Ideas??

THanks for the reply. Im gonna bring it back to the shop and get the timing set back to stock and see if things improve. The car made 110 lousy hp on the first pull on the dyno. I had my tuner friend Paul take a look at it and he said the air fuel ratio was super rich so he leaned it out by altering the AFM. WE did another pass and did 130whp. Still really low hp for 6 lbs. Im hoping turning the timing back to stock fixes things. Any thoughts?

When setting ther timing do I need to disconnect the TPS? I read that on one of the threads here. Thanks

I have a 78 280z with a stock L28ET swap( stock injectors, fuel pump, etc) and have the timing set to 8 deg BTDC as per the shop who did the swap. I take their word as they are the premier Datsun shop in the area. I checked the FSM and it states the timing should be 24 deg BTDC for the turbo model. The shop says they set the timing that way to avoid pinging when I turn the boost up to 10 Lbs. I trust them but want to know.....What you guys have your timing set to for stock L28ET swaps like my own? Thanks. Rick

My bad. I meant 24 deg.

Its a turbo so 8 deg give or take 2 is on the money!!!!

Well I stand corrected. I did look but mut have been looking in the wrong section. Thanks very much for the info. Rick

Its an 83. I checked the FSM and theres no info. I need to know whats stock timing. I was told its 6-8 degrees and Ive also heard its 20-22 deg BTDC. I need to know which timing is correct, where the timing mark is. Thanks for the reply.

Anyone?

I need a help setting timing for my L28ET swap. Could somebody give me a quick step by step for setting it to stock? The car as it is runs like crap and I believe the timing is to balme. Thanks so much and yes I have a timing light. Again thanks Rick

Its just i expected more power outta tge swap. seems kinda slow and from what i read the afm can make or break the swaps potential.Time to up the boost i guess.

Yeah. its a turbo afm. just making sure im getting the most outta my motor swap. I just got my car back from a local shop who did the wiring for the L28et swap and noticed the black cap missing and the breach in the glue. Car runs fine, just making sure ya know? Thanks

The black cover for my AFM was removed and it appears that the afm has been tampered with. One of the glue blobs looks broken for lack of a better word. Does everything look to be as it should to you guys. Thanks for looking.

You guys are alright. get back to ya.
