sif you didnt get it tuned properly... lucky it didn't pop.... no two cars even with the same setup are 100% with another tune..

The car would of run rich with that split so, not too bad!

In theory under vacuum it would run lean (unmetered air entering), under boost it would run rich (metered air escaping).. the damage done would be the unmetered air which isn't filtered

yeah not exactly a good result. my 32 with stock turbos, stock manifolds, stock injectors, stock cams, stock intercooler, basically 100% standard except for a cat back exhaust, 1 bar boost, and a well tuned power FC ran a 12.4 qtr mile. GET IT TUNED asap. it should be mid to high 11s at this point.

You are far too kind to the beast :D

A few people have run 11.4-11.6 now on stock turbo'd R32GTR's now. Just need to be nasty!

With those turbos you'd be WELL into the 11's, now just high - go for broken greaboxes

were you at the drags last night? I think i saw your car there with the SSR rims?

If so, it did sound a little lumpy too but I also wondered how it wasn't really pulling very fast. Mind you the R35 that was there could only manage around 12 flat anyway so I thought it must have been a slow night.

+1 on the tune then, spend $1k or so on a tune once you get the parts sorted and it'll be worth it...no sense in running it when it's not at optimal settings you could cause damage.

no 1 engine is the same.. you say the ecu is tuned for the turbos.. there is intercooler,exhaust,injectors,headwork,CAMS,and fuel pressure all to bugger it all up.

with those cams it will be way rich down low and super lean up top...

you need to get it dynoed or it will pop.

Yeh i was there last night. my GTR was the silver one with enkei wheels. There was a white GTR with SSR's and a lumpy cam though. He was getting ok times.

But yeh, Deffinently doing the tune, and im not driving it until i get that done. Today iv Booked it in at Xspeed for next month and they'll adjust the ecu and dial in the cam gears.

Im keeping the cams in. Because Planning for the worst case scenario due to the split pipe. I could have Overspun the turbo bearings. In which case ill chuck in some 2860-5's.

FARK ME youve spent alot of cash having all that done...headwork LOL. No wonder youre bleeding.

So no point telling you it was all for nothing I guess.

But what you do is:

Slap on a stock head, stock cams, stock manifolds, sell all your shiny fuel system bits to cover money wasted and use stock stuff there. Swap the Shitbro pump for a Bosch.

= Much more response and heaps faster 1/4 mile :)

ummm.... how about larger twins? wouldnt that be a better solution to get the most out of my setup????

rather than going stock everything like you said? Id rather not do that after getting all this stuff done...... :unsure:

All I want Is a good balance between response and top end at around 400ps. Which is what I would have thought the -7s and the cams wouldv given me.

Hell no

Larger twins (-5) will just get you more lag and power you cant use because of an unbuilt bottom end

For 400rwhp -7 or -9 is as good as it gets

Hey mate, I would not get too stressed about it all just yet. Why don't you see how the tune turns out first and see what they can get out of it with a bit of cam timing adjustment and so on. It may not even have the optimum fuel/ignition tune in it yet.

Once it's got a well rounded tune in it, see what you've got. Then make a decision from there. My guess is its probably got more in it as it stands at the moment - so don't spend $ just yet.

edit: Hmm just had a quick look. And i found quiet a large split in the intake hose that runs into the intercooler from the turbos.

Which would make sense cos i found i was losing alot of power in the higher rev ranges.

shit...

Iv been driving the car pretty hard all week. hope nothing else have fkd up on it.

Got it all put in and the tuner did a rough Road tune with the PFC. He did suggest however that i get a dynotune. (but the powerfc i bought was already tuned for those turbos)

Now i just got back from the drags and after doing multiple runs, ran a best time of 13.451 @ 102mph. uughh. wtf?

Can anyone help me out?

a rough road tune, then took it to a track??? well thats one issue

get it on a dyno and get it tuned properly...even if its not faster, its safer and may save you $$$ later

      Mistakes were made, my R34 Story

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.

      Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender

      I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
