Hey, once again, Son of Sydneykid

HKS make/sell tuned length exhaust manifolds.... They greatly improve exhaust flow. On the generic front, various places manufacture them. We are currently searching for an R31 GTS-R Skyline RB20 Exhaust manifold.....

The GCG Hi Flow uses all Garret parts, so it is a Garret turbo. It is also basically a NEW turbo after the Hi Flow as all of the parts that wear get replaced. And it will bolt straight back on. Just pick a level of horsepower.....they'll match it all up for you

Also grepin, have you upgraded the ECU..as it is not mentioned in your signature

Son of Sydneykid

I guess I should put details in my signature. I have everything I need to back up turbo upgrade. Even a second car if all goes pair shape. Because it is not a daily driver I can afford to go a bit wild. This is where my interest in not just going bolt on hiflow keeping it all standard develops from. However I am still practicale so also am not intending to throw lots of money away because it looks cool under the bonnet. Would still need regulator. May intend to do injectors and possibly Cams later.

Grepin

Your power output goals are not extremely wild, so the later 2 suggestions are probably not required. thge stabdard injectors are way fine until 300rwkw (i think, wil confirm with father)

I was reading the wrong person's signature when i posted that... i was reading rob's.... My bad.. its late ya'know

I am really interested in knowing exactly what you want from this car, especially if it is not a daily driver.... Makes suggestions a whole lot easier.. i tend to base most suggestions on daily driven road car, unless otherwise stated.....

I have one of those :)

on my car that is... with the RB25 in it :(

So how much does they floe Sydneykid? (if you know)

and how much extra does it give you ?

Like earlier turbo spool or high end power!?!?!

Not sure what the pros/cons are of these things... learn me away guys!!!

Hey rob

I personally prefer internal wastegates. too much extra cost and heartache with external's... And I prefer low mounted turbos...

R31Nismoid - Of course you have one.. very logical you would carry that over. they are good for bottom and mid-range power, hense why we need one for the race car.

Son of sydneykid

Hi Guys, we are concerned with handling as well as horsepower, so a low, rear mount turbo is way better for CG & PMI. We are not allowed to change the bonnet or cut big holes in it. So the hi mount heat problem on the bonnet is a big concern in longer races.

Larger diameter primmary pipes are better for top end and not so good for mid range, vice versa for smaller diameter primary pipes. There is still some debate on whether equal length is worth the trouble on a turbo car. On anything with more than 300 rwkw I believe it is, others will argue not.

Hope that adds to the discusson.

    • 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.
