I don't have any lamda sensors.... can this be responsible for my problem? I know that lamda are only to have better fuel economy at close loop.

How to melt a piston? At idle?? In neutral? Or in driving with 3k rpm? EGT not more than 500C and +100C because I measure it after turbo!

I will tune the car.... but I want to be sure that I don't have any other problem. The tuner is in an other city and I must send the car there. So if I have any problem there will be very difficult for me. Also it very strange to be the car SO SO LEAAAN!! Lean idle? Lean at 2000-3000rpm driving? The car feels like you don't have fuel in the tank and it is ready to run out of juice.

2.5-3 bar. We test with several fuel pressures... till and 7 bar!!! With 7 bar was a little better lol Any other idea?

Maybe timing?!?

Please check first my specs in my signature. My car start to work before two days but we have many problems!! It works VERY VERY VERY LEAN!! Lean idle (20afr), lean revs on the neutral (17afr) and lean in easy driving (15-20afr). Very very crap. It revs very very bad. Only at high revs (more than 4000) seems to work better. Ofcourse I don't try to run it in the road with boost but I did a burnout and at high revs looking very coool!! I am not sure what exactly map has the ecu but before I bring here a tuner I want to be sure that I don't have any other problem. It is a stock r32 ecu and I bought from gtr.co.uk member that he had 1000cc injectors z32 mafs and was twin turbo. He said that his car worked great but he bought the ecu second hand and the ecu writes that it was tunned with 660cc but his car worked good. I don't want to run the car in boost but it cannot run good neither in vacuum. It is the map sure? Or I must see for something other? With avc-r show me at idle that the injectors are open only 1.6% but I am not sure if the avc-r shows right. Do you have ideas? Something with mafs? Something I can check? I repeat tha I want just to be sure that I don't have any other problem and I need just a tuner. I am waiting your help please. Thanks!!!

Your 60ft? What size tires you have? Put in the rear your stock suspesion!!

1.506!!! Very very good But 7.1 isn't 600whp s14 must do something like 6.5!! Try more when you fix your boost problems My tires are better than your friend's... I have 15" so quite more sidewall!! My tires is et street drag too. Don't forget that your need also gtr hubs. What times did your friend and what horsepower he has? I will put also a line lock for easy burnouts!! My target is to do very low 10sec in the 1/4 drag races!! We have a race at 13 September and I hope to have my car ready to race

Guys you don't put them right.... You must put this solenoid in your front brake line. If at the brake master cyllinder there are 2 line for the front brakes you need two line locks if you have only one line you need one line lock. The differense is if the car has or not abs but I don't remember which has two and which one! You put the BRAKE pedal!!!! You push the bottun!!! Leave your brake pedal and forger it...! Feel free to PLAY with your clutch and your throttle pedal only...! When you finish the burning.... push again the botton... AND.... GO!!!! If you put them in the rear line you still need to push 3 pedals with two foots

waldoforce You don't have gtr diff+axles+hubs? Was a miracle that you run with gts-t or silvia rear end!!! I have gtr diff,axles,hubs and the center shaft!! You need hubs because gtr axles are thicker!! You run only 1/8? Not 1/4? Any issues with gearbox? Your twin plate work good? Fotos? Videos? 1.5 is very good I have Mickey Thompson 26x11.5x15 in 8" Weld Drag lites wheels! What rear shocks you have? Do you have any aftermarket links on the rear? Bushing? Do you have skinny front? I have 18" front for the time with 8piston D2 brakes I don't know what to put there..

waldoforce good luck and ofcourse we are waiting your results!! Also do you have any foto of your car? Video of your runs?

I don't finish it yet... We have summer in Greece now and it is great time for other enjoyments But I have a drag race to run at 13-14 September and I hope to be ready to race. So I will inform you about the car.. For the time I don't hear the engine to work yet

My car is single turbo.. I don't have any stock o2 sensors.. But I have wideband sensor for my gauge.. Wideband sensors (bosch) have narrow band signal exit.. Can I use the narrow band signal and send it to the loom? I must send the signal in the connectors of both 02 sensors? I will just connect the signal in the connectors? Nothing else? I have a base map in the ecu for the first "easy 600miles" tunned in japan for my injectors and z32 maf. After 600miles I will go to the tuner for a costum map.. but I want to can drive the car just decent for the first 600 easy miles. The tunner said me that the map he will make I wouldn't need o2 sensors... he will map the close loop without using 02 sensors.. Your opinions?

This cams was in the engine and I didn't know it.. Why you ask me? You don't like them? There aren't HKS step 1 springs! HKS produce springs step 2 and over... So for my cams? Stock springs? As with hks step 1 8.7mm lift cams? My cams are 9.32 and the step 2 is 10.2!

I can buy 10AN braided hoses and alloy fittings no problem. But where to find oil cooler with 10AN? I bought one the same as the jast jap... 8AN!

Just jap oil coolers are 8AN... all chinese oil coolers are 8AN. And unfortunatly I don't have money for jap brand oil cooler They are unbelievable expensive... I read for many people in the forum that use Just Jap kits! It will work or now?

HKS said to put springs for over 10,2 lift! My cams are only 9,32 lift.. I search hks catalogs and they sells "hks pro cam valve springs" for 11.6lift and "hks step 2 valve springs" for 10.2 lift I need or not? My cams maybe they are very old? Because in the catalogs of hks there aren't 9.32 cams! There are 8,7 10,2 and 11,6. Anyway my head was bolted to the car and it is very very difficult to put now springs and I will need again new gasket! But if I need them I will do it!

Stock valve springs, retainers, etc etc... What I need for 8500 rev limit?

I have stock head except hks 272-9.2 cams. What rpm limit can I use safe for my head?

Yes guys but the next questions is where to find BCPR9ES?? Very rare plugs

7 heat range? Noway! I need 8 or 9 but I don't know yet which spark plugs use the rb!! BCPR or BKR??

Thanks! But which plugs?!?

DiRTgarage you run 10's with single plate? You talk for gts-t skyline (rwd) right? 9's with twin? Again with gts-t? What horsepower had theese cars?

Not yet... I think that it will be ready on August. But I have some recently foto..

Hmmm... service manual says NGK PFR6A (platinum) so the replacement is BCPR6ES So the plugs I need are BCPR8ES or BKR8ES Also how much gap?
