Hi guys, I recently acquired a R32 GTR from Japan. The car is great. Just one issue, it is very laggy, on 1st gear i get max boost at about 5000 rpm, in 5th gear on the highway full boost is only at 4000rpm. Timing seems fine ,CAS is at center position. I cannot see the turbos clearly but the they look standard. Apparently the engine was rebuilt in Japan. Any ideas what can cause this lag? It has a jasma exhaust and decat.

Hi guys, I recently acquired a R32 GTR from Japan. The car is great. Just one issue, it is very laggy, on 1st gear i get max boost at about 5000 rpm, in 5th gear on the highway full boost is only at 4000rpm. Timing seems fine ,CAS is at center position. I cannot see the turbos clearly but the they look standard. Apparently the engine was rebuilt in Japan. Any ideas what can cause this lag? It has a jasma exhaust and decat.

Need more info, and timing can't seem fine, just looking at the cas doesnt cut it, get a timing light and check it out correctly. Non specific rebuild unknown turbos etc mean random people on the net wont know your problem.

Thanks, I have checked timing with a timing light and its on the spot. Also have apexi intakes. The car came with the Jasma 051 exhaust apparently it's a HKS exhaust in Japan, the cat was removed. It still has the resonator and muffler only, does anyone know if this exhaust is restricting my boost coming on earlier? The car feels crisp off boost and once on full boost it is very strong. It's just the lag which is a concern. The turbos are stock garretts.

Can I ask how much it costed you to import and register it?? I was thinking of doing that after u drove my friends r32 Gtr, they go hard and I think he has the same problem as you, I couldn't feel the boost coming in until after 4000-5000rpm

Tried to read the tag but it's almost impossible. I managed to view the compressor and turbine housing respectively, and compressor is A/R 0.42, whilst turbine housing is .48, this mean they stock ceramics? I also opened the cam cover and verified the pulleys lined up ,and they do, at TDC both pulleys line-up with plate marks. I'm now stumped, i need to check if there is a boost leak.

This my sound stupid but its worth checking the one way valve on your brake booster. Do you ever experience a very hard brake pedal after being on full boost? this happened in my R34 GTR and caused boost to come on around 500 - 800 rpm late. Its a very simple fix.

The one way valve at the brake booster is working fine. I am getting about 0.4 bar boost at 3000 in 3rd gear. Also vacuum at idle is almost -0.6bar. When the car is in neutral if I rev it, I get about 0.5 bar at 6000rpm. Is this normal for a stock GTR? The factory boost restrictor is removed, also exhaust is decat.As a test I disconnected the pipe with restrictor removed at the boost solenoid. hence no boost source to actuators. The car was still laggy but boost exceeded 1 bar for a split second. I didnot want to overboost and loose a ceramic wheel so immediately stopped.

Not sure if this is related to my lag problem , recently overnight I lost clutch peddle to the floor after pressing it, checked the clutch fluid reservoir and it was almost empty, I topped it up, afterwards I am noticing my clutch peddle is extremely hard to press but the clutch fluid is still full in the reservoir?

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
