Can you supply a fuel rail to suit these running top feed GTR injectors or can I just use a stock GTR rail?!?

Could you not use this?

It's not real, you have just hit the map sensor limit of a DD dyno! Look at this for reference of the same thing happening...

Fair enough, just so you know it's MORE than 31psi... By the look of it maybe a fair bit more

LOL only just noticed the intake temp, went to post and you had already posted... So dodgy temp correction and boost wound up so high the dyno can't even read, INTERESTING

So the dyno is saying 31psi but the boost reading is clearly being held back by the map sensor... So how much boost is it actually running to make that power?!? Plus, have you any graphs at a more reasonable boost setting? Say 22psi?

This post is useless without a dyno sheet

We also found this same thing when tuning my RB20. Was a bit dull up to around 20psi, came alive at 22psi (like put on 30kw with 2psi) and then hit a bit of a brick wall...

Tial 44mm will be fine... Would go a 3076R over a 3582R any day of the week though

Yes, but there is a few problems. First the standard manifold is split pulse so cutting a hole for a gate removes the dividers and screws up the flow of gases Second the standard manifolds don't like the be welded being cast and usually crack not long after being cut and shut A much better option if you want to keep the standard manifold is weld a gate to the rear housing of the turbo... Hypergear provide this service to customers I believe

HKS rock catcher!!! EEEEEEEEEEEEEWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW WWWW

Exactly the same boost, just more timing! The turbo is hitting a brick wall after 22psi

Might be 600rpm difference between your GTRS' but full boost at 5900 is at least 1800rpm difference between most T04Z results on a 2.6L and making the same power at the same boost...

Jesus, don't post a pic of Walbros on here... R31NISMOID will tell you they are only good for 200hp each! Looks like a neat setup

Do the T3 flanged ebay T67-25g bolt onto and standard manifold and clear everything?!? As in could you use them as a bolt on option if you welded a gate onto the ass of the turbo?

We found the same thing... We added both timing and boost at that power level and neither made any extra power!

Mine comes on like a freight train... You really do feel the difference between 100hp at 4000 and 370hp at 5100 Burst into wheelspin in 2nd and sometimes 3rd. Mind you mine is running a bit more boost than both your TD06 setups! Also shit tyres do not help Going to try a set of KU36's after I fix the gearbox

Good to hear you are back on board the power boat roy

I'm with roy... I think the 2530's will make it a bit of a dog E85 also wont help your spool, just top end power once on boost...

Saw your car on the weekend but didn't see you! Plus I missed you out on the track... Love the wheels, engine bay wiring is a bit of a abortion though haha Seriously go E85 or E85 50% BP98 mix

Nah he was going for it, just weak on gear changes! I made him pay and then my box paid for it

Managed to strip 3rd gear clean in my rb25 box about a hour later Not many 20's can claim to kill a RB25 box

Goes well in a straight line
