I have the 4 piston setup on my front-end and they work great. However you must do something with the rear or you will lock the fronts up alot. Now I just need to decide on a rear setup, hum emergency brake or not?? The one question I have is what are the Wilwood rotor numbers so that we can purchase replacements from say Summit racing? I believe they are UL-32 rotors and the part numbers are 160-5845 and 160-5846 but just not sure. What do you all say? HB280ZT

Setup in my 1977 280Z -Engine – stock tired L28ET lower-end, N42 head with turbo cam, 8.3+- to 1 compression ratio with Felpro head gasket, P82 intake manifold, 60mm throttle body -Turbo - T3/T04B .70 A/R compressor housing with hi-fi wheel, .63 A/R turbine housing stage 3 wheel, intercooler, 1st gen BOV, 2.25" intercooler piping -Exhaust system – 3†downpipe with custom 3†exhaust, Dynomax Ultra Flow muffler -Drivetrain – rebuilt 1982 280ZX 5-speed, Fidanza flywheel, Exedy clutch and 3.90 rear gears - Running 12 psi boost, comes on at about 3200 through 5800 then dies off - ECU - MS1 v3 Extra code -Fuel system - 460 CC high impedance RX7 injectors with Pallnet fuel rail, Aeromotive boost referenced pressure regulator, 255 fuel pump and custom 3/8 aluminum fuel line -HP – 298 rwhp at 5200 rpms, 322 ftlbs torque at 4100 rpms using a Dyno Dynamics dyno That was my old setup. I have added a few new items: -engine – rebuilt L28ET lower-end, same N42 head with 2mm metal head gasket, reworked turbo manifold n EGR parts -turbo – same system with Tial 50mm BOV, old one leaked pretty bad -Running 15psi boost, car pulls hard through 6000 rpms -HP – no dyno numbers yet still working out a turbo surge problem will update when I get it fixed HB280ZT

From what I can remember they are using a hydraulic throwout bearing on there set up. Take a look at the top of the tranny and you will see a hole drilled into the bellhousing to run the lines. Hope this helps. HB280ZT

If you change the bell housing over to the one from the S10 then will resolve the tilt of the tranny, check out this picture: Not sure how much it would cost at the pick-n-pull but it might worth a try, could be cheaper then a new shifter. As for a shifter try the one form an S10 because it is longer (can be cut down) and has a better throw. As for the bell housing it also is used to convert from a FWD motor to RWD. That way you can use a newer 3800 series motor like the supercharged engine (260hp or so) or the N/A motor (220hp). Also the fuel injection systems on the newer motors is better then the older setup. Also if you are interested Brunton has the ability to remap the factory computers for better performance, just athought. Keep up the great work and we need more pictures!! HB280ZT

Well it is looking good so far. With the room you will have between the engine and the radiator you could put a turbo or two without any problems. I believe when using the Camaro engine and transmission it tilts the tranny one way or the other can't remember which. So how does it look from the drivers perspective as for the shifter and such? Keep the pictures coming and let us know how it all turns out. HB280ZT

Hi All, Watching this thread with much interest as I need a new turbo manifold!!!!!! Can we get the turbo mounting flange drilled and taped for an EGT sensor? If yes put the sensor in from the rear of the flange and or plug it with a 1/8 npt plug! Just a thought! HB280ZT

Hi All, Well we have a guy down my way that uses the Supercharged 3800 with a T5 in his custom cars called a Brunton Stalker: http://www.bruntonauto.com/. They even remap the ECU to make them run better while racing! The owner Dennis Brunton holds time trail record at several track with his Super Stalker. Well enough about the car I want to get someday! Back to the question that someone asked about the tranny. The tranny bellhousing that they use for there conversion is from an 94-95 S10 2.2L engine only, with stick shift. The tranmission was a 96-02 Camaro V6 T-5 unit. He also uses the S10 shifter but cuts it down to size. I have stopped by there shop a few times and someday I will have one of there cars. They are replica Lotus 7 kit cars and they are also very fun to drive and very very fast!! Hope this helps you all out some and we need to see some pictures!!! HB280ZT

I have done a search but did not see many pictures that show the side sections of the spoiler and where it contacts the fender and wheel well. That is the section that I need pictures of. So if you have a MSA type 3 can you show me some pictures of how you trimmed the air dam to make it fit. Or if you do not have pictures from when you installed it a picture of how it looks now would still help. Thanks for the help. HB280ZT

Hi All, Well I finally started to install my Type 3 Air dam and it seems that it does not fit very well. I understand that it needs some work but I would rather ask questions prior to cutting. So my question is how much trimming did you need to do on the finder sides to get the air dam to fit? Also was there any other areas that needed work to make the air dam fit correctly? If you have pictures that would really help out alot. Thanks for the help. HB280ZT

I gutted out an 83 turbo intake manifold and here are a few pictures: I never cut off the top EGR stuff I just plugged them. I also used 6 1/8 aluminum plugs to close all the egr ports in the bottom of the intake runners. HB280ZT

I have to second or third that Todd at Tidewater Z is the only person in the Tidewater area I would trust with my car, I did when I lived there. If you have Z questions you need to talk with the people in your area Z club: http://www.tzccva.org/ Enjoy! They have a great club and have lots of fun. HB280ZT

I think one of those motors would go nicely in a Datsun roadster or a 510 coupe! That would be fun! Would definitely kick some Miata butt!! HB280ZT

I put the bad dog jacking plates on my 77 280Z and they work very nicely. The only item that I found was that you really need to run a few (3) beads the length of the plates so that your jack has something to grab onto. I had my car fall off of the jack plate because they are nice and flat! Other then that they work very good! HB280ZT

allaboutdaz We need pictures and more information about size of rims and tires!! HB280ZT

280~master Hate to bring up old threads but I am interested in whether or not you got the escort/taurus fans to work with an S30/L-series configuration? Also if you did pictures would be great. HB280ZT

This is a great idea. Now you need some flat black material as a mounting surface. In that mounting surface you can put your Megaview, several leds and maybe a push button or two. How about: shift ligths turn signals indicator lights - whatever you need to show?? O2 cal button - like that idea VE-Spark Table switch button?? I will have to keep up with this because I also need a new tach! HB280ZT

Well, I was not sure if the change of boost reference would do anything to the way my car was running, however, it did! I now have to work at it to make the car flutter and this is only a temporary fix. You see I installed a fitting within 1 inch of the turbo output in the intercooler piping to use as my boost reference point until I can take my turbo apart and have the compressor housing machined for a fitting. So now I can really work on the tuning and even look at how much boost is lost between the turbo and intake manifold. May or may not be a good thing! Everyone thanks for your help and I will keep you all posted on how things work out in the long run. I still have to do some dyno runs and hopefully several events at the local track, Sebring!! HB280ZT

OK, Thanks for the information, As for changing the boost to 10 psi or less it really does nothing as my problem is not really when I am in boost. This happens at part throttle above 3000 rpms and at or below positive boost level. One question that I do have is concerning the TP information obtained in MegaTune. Who has watched it with the car on but not running to see how it functions. I did and got very interesting readings as noted in an earlier post. So can someone do the same test and let me know what they come up with? Also something else that I am doing is changing my boost reference from the intake manifold and moving it to just after the turbo. I am doing it this way right now to just check if it makes a difference. If it does then I will see about tapping the turbo compressor housing for the boost reference when I have the system taken apart later this year. Will keep you posted. Harry aka HB280ZT

OK people I have finally tried everything that my local Z friends and I can think of and it still flutters, BOV removed and blocked off, wastegate wired shut and vacuum removed, more and less timing and fuel. So that being said I plan on removing the turbo and having it looked at by a local shop that the Z racers use and swear by to make sure it is good to go. As for the intercooler is there a place I can send it to to have it checked and flow tested to see if maybe it is causing an issue?? But for now I have to get ready to move then it will be time to play again on my Z. Thanks for your help. Harry aka just call me flutters!!

Hi All, Here is an update. I have tried high spark and low spark and it still surges. That being said I do not think it has anything to do with the spark or fuel setup that I am running so what can it be. I have also worked with people here in town that are using the same hotside that I am with larger compressors and not having any problems, i.e. one is running a T04E with 62-1 wheel and the other with a T04E with 57 wheel. They are also both running N/A computers, (1977 and 1975) with MAF modifications and methenol injection over 8 psi of boost. Neither one is having any surge problems. Please do not tell me that you can not run a turbo motor with an NA computer because they do and it works. As for changing out the hotside I really do not want to do that as it would require me to also change the exhaust manifold and add an external wastegate, can you say lots of money and where to get a custom exhaust manifold that will not cost me my first born. So I must have something wrong with the setup in my megasquirt. That being said who has a 29V or 29y4 program that works with a motor setup that way mine is? Setup again; MS 1 V3 with 29y4 Extra code 82 ZX turbo motor with N42 head using turbo cam, 8.2 compression ration 2mm steal head gasket T3/TO4 turbo intercooler Tial BOV running 15 psi boost manual DIY boost controller 60mm TB I really want this to run right so hopefully we can get this thing figured out. Attached are several spark tables that I have tried and my last datalog and msq. datalog200803151706.zip megasquirt200803151551.zip

Clifton, I checked my TPS again today and found something that I am not sure is right. First I calibrated the TPS and got the following: 38 closed 199 full throttle Then I brought up the Throttle position on the MegaTune and it reads: 15 closed 78 full throttle To me the last part is not right. I can see 0 closed and 100 at full throttle. So what is up with that? Will look into the MegaSquirt manuals some and see what is up. If you all have any ideas please let me know. Thanks

Hi All, You can get strut collars for 240 and 280Z's here: http://www.designproductsracing.com/Z_Suspension1.html Hope this helps.

Clifton, The compressor side is a 60-1 hi-fi or that is what I can figure out. James Thagard made the unit for me and he called it a hi-fi and that is put out 55 lbs/min. So that being said if I change to say a H trim (49 lbs/min) will that help out? Anyway i do it I need it to pull good through 6500 rpms and make about 350 -400 rwhp. Thanks for the help.

Well I had a chance to check the TPS and it checks good, as far as I can tell. Also plugged the BOV and it still flutters. Have tried several different timing maps and it really did not help at all. Here is a quick datalog that shows just a flutter sequence. One of the items that is concerning me is that the Map and boost is dropping at the rpm is increasing, is that normal? Also you can see how the boost and map are bouncing around. If it is the turbo what to change? T3 turbine AR .63 stage 3 T04B compressor AR .70 hi-fi intercooler 8"H x 20"W x 3.5"D 3" in/output intercooler piping 2.25" Hope this helps narrow down items to try next. datalog200803102036.zip

Clifton, I set the TPS via megatune when I setup the program. You know at no throttle and at wide open. I will go back and look at it again.
