Turbo

Whats the best watercooled turbo? anyone know out there???

[SkylineUSA]

Best for what? Cooling? Power? Spool time? Lasting? Torque? Street power?

[xToRQuEx]

overall best, ability to push me from 402whp to 800 with a lil help from other parts i drop in. (after engine rebuild and tranny,cams etc)

not doin this anytime soon but id like to be doin my research.

[SkylineUSA]

You want 800 to the wheels?

Your going to need a heck of a lot more than just a turbo. I do not know why people get stuck a high horse power numbers.

If you build a 800hp car, and if its set up like all those Supra dyno queens. I could build a 600hp GTR and kick is butt.

Don't get caught in in the numbers.

What is your goal?

Best bang for the buck turbo wise are the HKS 2530s. If you want to do engine work, the HKS GT-RS are probably the way to go.

If you really stuck on the 800hp thing, a big T88 will probably get you there, but cars built like that are too laggy for me, plus more crap will break.

You could always use a shot of N2O to get you there. Direct port of course.

Well this is way off in my plans. im plannig on getting a tranny that can comfortably hold more power first, then the engine rebuild. Then i would shoot for the turbo upgrade with the outlet pipes and what not at that time.

if at all possible get 800 with no lag, and no nitrous considering id rather not have it. this isnt set in stone tho, playin with options and information, still have time on my hands.

Sky, I heard that the GT-SS is about the same size (maybe smaller than GT2510) but cud give a 2510 output. Is the GT-RS about the same size as GT2530 but with greater power output potential? Wud appreciate your help.

[xToRQuEx]

are either of these water-cooled?

[R33]

I don't think so. They are oil cooled.

[Ebola 33-t]

With an oil cooled turbo, are the lubricating and cooling sections kept seperate, or does it all run off the engine oil? Secondly, am i right in guessing that my T04 is water cooled, but uses oil from the engine to lubricate?

I do not know from personal experiance, but I have read on more than one board on the subject. This is what I know. The GT-SS is like between the 2510 and the 2530, but with its more updated design will spool quicker than the 2510, and produce more power than the 2510, but it will not produce more power than the 2530. The power band is a little better than the 2530, but the top end power of the 2530s are much greater than the GT-SS.

GT-RS is compared to the 2540, but with a bigger top end, and spools quicker, but in order to make that power you have to go into the engine and dump a lot of cash. With the other 3 (2510, 2530, and the GT-SS) they are almost just plug and play.

The GT-RS will need and ECU controller of some sort, just like the other ones, but it will need a much bigger cam for breathing, port work, much bigger injectors, and you will have to run a stroker for the volume. Yes, it will produce a lot more power on top, but the power band will not be as good as the first 3 mentioned. I am all about the power band

Personaly I would take the GT-SS out of all the turbos mentioned, but I would not build the engine like the typical tuner. I think a little different.

Why are you wrapped up in the water cooled turbo stuff? They will last just as long as the typical oil cooled turbo.

[R33]

Yep. That's what I heard too. GT-SS looks like a nice idea! A friend of mine had them installed on his 33GTR. Nice power band, as you said. Spools up really quick...in 5th it starts boosting at about 2300rpm (if I remember correctly) and by just above 4000rpm, it achieves full boost! Sounds really good actually. Am thinking of them if I have to rebuild my engine or for this endurance race (if I manage to buy a 32...which is so darn difficult to find around here!).
Thanx for the explaination.

[SkylineUSA]

See, in order for the 2.6 to make a lot of power you have to spin that sucker. High RPMs, and you know what Rpms stand for? Ruins People's Motors That is why I would not go for the 2540s or the GT-RS.

Really? And I thought thsy meant "revolution per minute"

Prefer water cooled because they need no turbo timer. small but a reason

[R34 GTR]

All of the above mentioned turbos are water cooled IF you make use of it! When I had my 2530's in my car they were oil & water cooled. The turbo's water in/outlets were the same fit as the stock turbos so no need to fabricate new water pipes. So why not use it as extra precaution?

On my friend's 2835'ed Supra, he has not use the water cooling option as the stock water pipes weren't the same fit and he has a turbo timer!

I am going to use the GT-RS's this time round in my new engine as got used to the power of the 2530s . They are suppose to be suited to a 2.8L stroker kit. Anyway, they are going to be matched with high lift 272 cams. From my guess after seeing them, it looks like they are a hydbrid of 2835 & 2530 turbos:

2835 compressor wheel
2530 turbine wheel
