Im sceptical just as URAS is untill I can see correction figures.

Get them to run it up after the tune in shootout mode and make sure there are figures at the bottom like this one has.

Fairly easy to define a legit graph to a dodgy one then.

tell me what i need to ask for when he does it again on saturday, the HP figure means little to me but a safe AFR does.

Next time i will leave the arabic writting on the sheet so you can read that too :-)

yer i reckon i can ask him to do that thanks for the info

And another thing is with these turbos and no supporting mods you can expect bad compressor surge, as I've just found out! My GTR's barely drivable around town! So it looks like it's back into the garage for mine until I can afford the required extra's. :D

Well let me rephrase that.. just forewarning you... it's a possibility that you could end up with an undriveable car due to shuffle because of no supporting mods.

I have bugger all mods at this stage other than the usuals i.e exhaust, pods etc. No after market engine management (mines modified). One of my original turbo's shit itself and I plan to do quite a few mods later on and so wanted turbo's that will be up for it later on down the track hence the GT2860-5's (Never pulling them off again!! What a shit of a job!!!) And now have bad shuffle at cruise and low speeds.

Turbo's ,especially 2530(-5)or GTRS(-10) for a gtr need some mods.

1-Exhaust should be at least 3" right through...including CAT.(Air)

2-Fuel pump replaced to NISMO with regulator.(Fuel)

3-A tune is required with an after-market ECU.

You don't expect more power when the Engine is in a mild state of tune...do you?

How do you expect things work...get a Turbo('s) that is larger and assume the car will be better...wrong?

You made the right choice with the 2530's...you just have not been listening to what every-one is saying.

Get yourself an ECU and get a tune

hmmm you have other issues, even though im no fan of 2860's i have fitted them to stockers b4 with no hassles in fact i just fitted larger T517Z's to my missus's RB26 powered silvia and it drives fine (no boost etc) of course it needs a tune but it would be safe as houses to go to shops and back....even as a daily commuter it would suffice until dyno time should present itself.. road tuning ruled out on this one....its a bit anti-social.

Yes i know and if you read my post properly it explains my reasons for putting these turbo's on without any supporting mods. JohnnyT originaly asked if his car would be ok with -5 turbo's and no supporting mods. And I'm simply saying that yes it will but he can't expect it to run properly..... like mine.

Hmm, possibly do have other issues, I didn't change anything other than a small amount of metal off the exhaust manifolds??

      From Japan and back to Europe, my sh*tbox R34 GTT

      By GoHashiriya · Posted

      Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.

      WTB R34 GTR Guard Liners

      By Kinkstaah · Posted

      Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?

      I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
