Oh yeah that also means another trip to Yavuz for more boost and an aggressive tune.

I would LOVE to see it crack the 500's with stock GTRS's and a stock ported head. Others have had big results with GTRS's but only on ported heads and the turbos being modded is also a consideration.

Seeing as its on E85, he may aswel make the most of it before the next motor is finished for it cause this current one wont be in there much longer.

I know Yavuz is reading; Yavuz, remember, give it loads :)

Ill take your old engine steve-o :)

Man I wish I could go out for a spin to see just how insane this is, havnt been thrown in the back of a seat in such a long time..

Just finished my little ol turbo conversion, gotta make a date with yavuz to get it all tuned up.

Love the work..

Doing a new build thread for the new engine?

Ooooh definatly will do :)

Cheers!!!

Not sure yet actually, missed a call earlier tonight about it and its too late to call back now.

I want it to sound mental, which shouldn't be hard given the cams its got.

Im concerned as my car is so low that the front pipes will get damaged on the very ordinary Sydney roads and speed humps, so yeah undecided so far.

Front pipes i'm thinking 3" into a 4" merge, then 4" all the way to the rear.

Will be very loud, so once its on the car there will have to be some fiddling with mufflers/resonators to shut it up a tiny bit.

Oh, and something that resembles a cat converter.

the front pipes will be challenging!

westside muffflers in padstow do very nice work & are well priced, he does all of pacmans cars & gas-250!

Steve, there's heaps of room under a skyline to fit massive mufflers. Should be no problem keeping it quiet with a huge pipe.

Mine's fairly quiet (Well I reckon it is, you make up your mind), and I still haven't gone as big as possible on the straight through mufflers...

lol, there's a line for it :D

Ill take you for a quick spin if you want

Yavuz's work is great, you'll be happy!

Yep definatly doing a thread for the new one, ill post it up once its all finished though, not in stages

lol mate who said i want to shut it right up, we'll see how loud it is, then fiddle with it to make it streetable.

The car is so low im concerned about clearance, i guess thats a bridge to cross when/if it arrives :)

Cheers buddy!

This weekend is all about the booze, and watching others at racetracks :)

Did yours go to get tuned yet?

Nah I havent yet. Gotta put this stupid cooler on. After being off the road for so long im enjoying driving it again. There is a little bit of mucking around with putting this kit on. I want to retain the Factory BOV setup so I have to get someone to mock up some alloy piping (re routed behind the rad). Then the decision to go E85 or not. ARGH!

You going to convert too Marko?

When I was building my engine that was the plan, hence why I opted for 1600cc inj, dual fuel rail, surge tank and 3 x 044s BUT the inconvenience of driving outside of sydney and not having access to e85 keeps stopping me...curiousity might get the better of me 1 day

Thats an easy one, drop it off at Unigroup and let them deal with it :)

Or take it to somewhere like Hypertune and they can do all the measurements and fab work, then off to tune

What power do you want from it? I think ive asked before but its slipped my mind.

Yavuz will say use E85, end of the day its your car. I want every last KW out of it so i have zero regrets once this motor is gone, so thats why i chose it incase that helps your choice?!

Steve - why did u stop @ 24psi on e85? I was told that 30+psi is not an issue on this rocket fuel :)

The exhaust is restricting it, yes it will go into some really silly numbers but the exhaust on there is at its limit

Have a look through the forced induction area at exhaust threads, everyone who knows their sh!t says 3.5" for even 350kw. This varies between 70 and 80mm. So its far from optimal, but its still going ok when you consider from the cat on its one of the first xforce catbacks made.

The exhaust shops i've contacted for the custom system cant believe the power its making on what its got.

If anything, it gives me confidence that with a custom exhaust the numbers will be achieved nice and easy so the motor isnt too stressed out

If I upgraded my exhaust there would be gains to be made...I have a hks superdrager which starts @ 3.25inch, then steps into 3.5inch and becomes 3.75inch near the diff lol

What are u paying for your custom system? If u prefer send me a pm

When are you doing that?

That 20awkw, if that is the exact power gained, will cost you around $1500 if you're talking a custom 4" Which is a pretty expensive gain

Im trying for another 70/90kw but on more boost and tuning. I don't see how another 6 or 8 psi cant net another 50kw at least with a much higher flowing exhaust

yes well if im easy with the box it will be fine - feels good to me thus far.

i know what u mean about $150/kw for the exhaust upgrade - apparently the 98 pump as of lately has been poor in quality so going the e85 route will be much better bang for buck.

$1500 for a 4inch exhaust sounds a bit as well, i'll make some calls & see if i can get a better price, is that price for s/s?

    • Hi Rob It's a nistune ecu. Yes same shop, good reputation. Apparently the computer on the dyno is compensated for temperature.    Chris was saying that the lean or richness of the mixture would be covered in the actual tune, but he's already picking up in advance that it's under what it should be. Regards the dyno, it's also noticeable on the road. But I just want to add something that has just come in, it appears there might be something in the setup of the external wastegate. In the exhaust manifold there is a centre divider between the front three and rear three cylinders. The external wastegate has a pipe from each side that join at the wastegate. Theory is those two pipes just might be pypassing that divider and introducing a problem somehow. Is anyone familiar with the divider in the exhaust manifold and the effects if the two wastegate pipes were to create a bypass path? Thanks for your questions Rob, interested in your thoughts on this external wastegate bypass theory. Regards Rob
    • Meh, At 60 years old, I have been doing dumb stuff for much longer than you mate, I am the true King And unfortunately I cannot be a maroon, as I am not brownish red As for not getting ITB's, the plenum intake will apparently show typical gains across the board and increase induction noise a bit, but, have all over less dort than ITB's Cost difference for the extra ITB dorts was significant though, the total parts for the plenum set up is "around" $2kAUD plus shipping, the ITB's were $4kAUD plus shipping, I was contemplating really hard about paying the extra $2k for all of the dorts, but weirdly, some form of common sense, from listening to the platform experts prevailed  As for the NA mod hate by some, I've had a few boosted cars, with all their inherent issues, I'm now looking at simplicity and legalities for a street car, maybe I'm just getting old, and I'm quite happy to spend some of the kids inheritance, 5kw at a time 馃ぃ And think of all the money I'll be saving on consumables that something with boost needs, like engines, gearboxes, diffs, clutches,  tilt trays... etc. etc. etc. 馃お
    • Haha.  I wouldn't say I am either but I've definitely been around it plenty.  I'm guessing you know the dial in is basically to make a handicap to level the playing field between racers.  The car with the slower dial in goes first and in theory if they run their dial in time and the faster car also does then they cross the finish time if they also have exactly the same reaction time - if you go faster than the dial in them you lose, but if you are too slow there's a good chance the other person will get to the finish line first. I'm normally supporting other cars but they were all pretty dialled and were egging me on to race as well, here's one of the cars I tune (Starlet) which ran within like 1 hundredth of its dial in through the competition: https://www.youtube.com/watch?v=inEBu-d9Gn4&t=69s
    • Where ever the fuel reg gets it reference is what I use to T into for map reference been a very long time so where it goes to plenum/runners I have no idea but never had issues. 
    • What ecu? Same shop every time? Same ambient temperature? If timing is correct then pull plugs and see if lean or rich. Dyno can also read different if they have changed ramp rate or not set tacho/speed properly
