Hi. Ill try and explain the best i can as not very good with all this writing stuff..

anyways i bought a 1990 300zx tt the other day, with low milage and full service histort. It looked like it had been stood awhile tho

. When i went to pick it up it seemed like it was only running on a few cylinders.. This helped alot in knocking the price down severly.

Anyways i ended up getting it very cheaply.

we trailered the car away. Got it home and after a bit of research i decided to get some new plugs,fit them,also did the injector screwdriver test and found 2 of the injectors wernt working, i removed the plugs off them and found them to be green.

I cleaned the terminals up and refitted them. Started the car and great it ran sweet as.

After doing an oil,filter and coolant change i took it for a run.. Everything seemed fine until i tried to floor it.

Absolutely no boost. Car runs sweet, the stock boost guage goes up to the 0 then stops. When i slow down the guage goes back into -..

Cant even hear if there spooling or not..

Al i do know is there is no hissing or strange noises from the engine bay. Ive had it on the ramps today to check as much as i can and all seems fine no apparent split hoses, turbo's and actuators all seem fine and are where there sposed to be..

Totally at a loss now and time to ask for some advice

I know my way around jap stuff and have owned a wide variety of old school jap car but have nevet come across this before..

Last time i had a similar issue was wirh my r32 skyline but even tho it had a boost leak u could still hear the whoosh as the turbos spooled but obviously didnt get much boost but it still ahowed on the guage as boosting..

This car doesnt even get past 0 pn the guage lol

Now ive checked with the service history and everything adds u with the milage and its the original engine according to the numbers.

What i did find tho was a receipt for a superchip, performance exhaust,top end overhaul to the heads and a refurbishd and uprated gearbox to apparently handle the extra hp. Thr dyno receipt shows 376 bhp??

This to me sounds odd as i think it would ov needed more extras on it to make that kind of hp gains!!!

I havnt fine through all the service hostory yet as there is so much..

Also ive noticed there was an ebc fitted but it has been removed

Any help and advice would be greatly appreciated

did both turbos with out taking the engine out or lifting it...... am i good??

only had 1 stud snap on the elbow but had a spare but sooooo many injuries to my hands lol

had the car up and running today, went for a test and i got boooost..lol

only boosting to around 6 psi but ill be looking at that tomozz.

think i mite have put the baileys and the bungs in the wrong places as it doesnt seem to blow of..pistons open and close but no woooosh.ill swap them over tomorrow:)

but damm they do boost hard..wasnt expecting it to take off like it did..

the passenger turbo we removed 1st looks like a recon unit,never seen a turbo with that little play in it!!!

thatll do as a spare.lol

had to remove the aircon fan to make way for the ARC airbox so decided to remove the rest as it didnt work that well anyway.

should allow some more airflow to the rad:)

is there any difference between a h shape centre section and a x type??

mine has an x shape centre section with no cats straight to the rear boxs but its not loud enough (well for me) lol

couple of picks from todays antics

 

think the baileysare in the wrong place???

bayleys don`t do whoosh :) my car is boosting 14 psi

Its all blowing of fine now. I did put the dumpys in the wrong place.. Lol guess thats what happens when you are doing multiple jobs at the same time:)
