Hi bazr33, I have yet to find an aftermarket turbo that bolts up, I have had to fabricate/buy stuff every time. That's why I use lots of the GCG ball bearing hi flow R33 GTST/R34 GTT turbos, now they bolt straight on, no mods or stuff to make or buy. I strongly suggest you do a search, there is plenty of info:cheers:

HKS 25** series do bolt straight on with a T3 flange.  Although you will be up for new oil and water lines which im scrambling up at the moment

Do those turbos bolt back up to the stock dump pipe as well?Or is it only the oil and water lines that dont line up.

its pointless statement really .. i have a high flow dump pipe, and its exactly teh same bolt pattern as the standard dump pipe, so high flow dump, or standard it makes no difference .. it;ll bolt straight on ....

no meaning to flame here, but just pointing out they are the same ..

personally i'm going down the router of a GCG high flow. ... as soon as I have time to get over there and pick one up that is ...

Isnt that a bit of a waste though? if you have a HKS GT25 turbo and still use the standard dump pipe? how much power do you lose?

What about the inlet piping and compressor outlet piping? how do they bolt up?

Yes will be a waste, certainly that will be your restricting point.

Inlet piping is the same, outlet piping is slightly different, you have to get a 90 degree turn, I got the HKS one, its alot better flowing than the stocker.

I would be going the HKS 2540. If you get the kit it comes with everything needed to bolt including the coolant lines. My mates r33 gts-t has run a 12.3 with one of these turbo's on a dead stock motor.

Nice time, it all depends on the driver, someone on here has done a 12.5 with a 2530, your mate has done a 12.3 with a 2540 which is awesome, but then i know someone has done a 13.4 with a 2535. And then ive done a 12.9 with a stocker.

Well it shows the true potential of each, certainly the 2535 has more left in it.

About the 90deg return piping, is there a way to stick with the stock one? or do we need to fabricate a new one?

Oh and does anyone know what kind of restriction in terms of power the stock dump pipe is?

You could possibly just buy a 90 degree hose instead.

Off topic, question for the people with 12.3, 12.5 and 12.9[stock]...

Do any of you beat gtir's? I'm not talking about a rolling run, I mean at traffic lights(provided its safe)?

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
