Then I have to ask the obvious question... Why are you running one?

I have plans to track mine, and at nearly 3 times the stock power I was a little worried. Now I have the sandwich plate fitted with temp and pressure sensors, I can see stable temps on the road but give it a squirt and they shoot up.

Because our car was not really designed as a ..... Track bitch......more of a family cruiser.....had they done a sports version of the m35 like the 260rs.......well we have all seen the 380rs haven't we!!!

Lol. Well I worked out my two choices, the Stillen and Nismo, would both be about the same, so I went to order the cheaper one (Stillen) only to get reamed on freight. So ordering the Nismo in the morning.

Cheers for the advice Craig! :thumbsup:

got my car tuned and made an appallingly low 306hp on 14psi, thanks hypergear for ripping me off.

306hp @ 14psi?

Is that AWD HP too (include losses)? Through an automatic (more losses)?

I'd say that's F&*ken awesome!

It's like 400HP at the motor!

If the AFR's are sweet and within limits, and the torque curve is flat what are you complaining about?

I'm saying that is maximum boost. The turbo has a spike to 20 then fall back to 14psi.

Any ideas as to why the turbo is dropping boost? I mean apart from the turbo is crap. I had a similar problem, turned out to be the cat was too restrictive and choking the exhaust flow.

306hp is a good result for 14psi though.

I'm happy with the figure, it's back to stock power. But considering I bought a turbo rated to 375hp I'm unhappy with the result. I'm wondering if it's a wastegate issue now.

Stock is more like 200hp/150kw. So you've got a descent increase over that.

If you can get the boost control issue sorted I think you'll be happy. Most larger aftermarket turbos don't come into their own until up around the 20psi area.

Started changing the dump pipe on the M35 this arvo, bloody hard to get into the top studs. 2 bloody studs snapped rant.gif

Rang Nissan and NO studs in the country, ex japan for bout $125 for set of 5 studs with nuts. I was hoping the rb25 studs would be the same but they said they are a different part number.

Does anyone know if a stud is available from anywhere else? Im getting Captain Thread to go to my mates workshop, where the car is stuck on the hoist for the weekend, to remove the busted studs monday arvo.

lilcrash - hypergear turbos are meant for peak power at over 19psi. I suggest fitting a heavy duty actuator that is rated to 'round 17psi (garret, gcg, or talk to stao and haggle for his HD turbo actuator. Slight retune after fitting & the 20psi boost spike will only taper off a couple psi. You'll gain another 50rwhp I believe.

I went from a 1bar HKS on the gt3076 to a 18psi garret actuator and came away with a decent 20kw increase. You want an actuator rated as close as possible to the boost you wish to run.

Heavy duty actuator rated around 17-19psi will unlock the turbos TRUE power potential.

    • Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?
    • Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).
    • So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?
    • Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
