Hey chevyeater, you say you can get the group A cams how much are they and can I get a set? lmk

I found a set by looking, and posting that I was looking. I'm not looking anymore. They were found on Yahoo Japan auctions. Significant modifications are required to the cylinder head to even install them. If you are on a budget, forget about these cams. Something with less than 9mm of lift would be a better idea. I hear that webcams has some nice grinds for the 7M.

I've never heard of a racing team that runs camshafts until they wear out or only has one engine for thier race car. :rofl:

Tim any more info or close up pics yet? I have the Turbo A ECU(confirmed). I'm told I have the complete Turbo A harness from the seller.(Still trying to confirm the harness) I've also been wondering why my harness has (2) identical pressure sensors. Sorry I'm technically challenged and am trying to figure this out myself..

are you sure they are exactly identical? according to the japanese EPC, the TurboA indeed has two pressure sensors, one with the P/N 89420-14050 and one with 89420-14020 (which is the same as on all 88-90 turbo MKIIIs).
probably one is for the ECU and one for the boost gauge?
here's the EPC diagram.

IIRC the plug for the turbo pressure sender is on the body harness... its not on the3 engine harnnes.
I am still trying to get answers on the intake air temp sensor. Where to put it.... Where to pin it.... Stuff like that.
If you have the harness then maby you could help me with that.

89420-14050 is the part # for the map sensor that is mounted on the Firewall of the Turbo A. the other is for the boost gauge.

If you have the harness you should be plug and play. That is if you have the map sensor... I did run that part # and so far the price was like over $400.
My motor is not out yet as i havent had much time..... I will keep you posted.

Well looking at the two sensors on the harness I have, I can confirm the numbers on the one as 89420-14020, the tag on the other sensor the numbers are worn out and I can't make them out.

Is the sticker on the sensor kind of orange? if it is then thats the Turbo A map sensor!!

If it is yellow then it is the boost gauge pressure sensor. The sensor i am going to try and use is 89420-14020 which is the boost gauge one. If that dont work i am going to try a GM 3 bar.

I ordered a new harness (a usdm one) but you should have it kinda easy sence you just have to plug it in and go to town.

Did you find a plug for an Intake air temp sensor? I am still looking into that. I will let you know.

do you have Yahoo or aim so we could talk more?

Sorry Tim, I'm not on either aim or yahoo. I sent pics of both my ECU and harness to maeso. He commented about the ECU but never got back to me about my harness for some reason.. :confused: Anyway if you want to get ahold of me just email me: dgnak@telus.net and can talk about it there if you like. The set up I have has made some supposed impressive numbers. Just from the TRD cams in this engine alone I tend to believe that.

drjonez, I have been wondering if you could make heads or tails out of my harness if I send you some pics as to where some things may go as this may help us both out here. I'm sure you've seen pics of the ECU. It's the one with the control box mounted on the outside of the cover..And to answer your question, yes I am the annoyance that bought your J tube block off plate..lol..Thanks for that by the way as it made it here in one piece..If I can return the favour LMK anytime.

Don.

Send me those harness and ECU pics as well. My ECU has no control box on it... I will post pics of mine, and yours on this thread if you want.

I have the Turbo A cams in and let me tell you, I can get more power up in the 6000 range than i ever could. i am getting the head over to the builder this week and see if he can measure the Cams to see what they are all about. I will give this Info to DrJonez
