Merli, GT-SS ?

[Skylineusa]

I read a thread from a few months ago about installing your GT-SSs, but I cannot find any info after the installation. Were they installed? If so, could you give me a link to what you think of them.

I just bought a D- Jetro with all the trimmings, now I am trying to decide if I want to go with GT-SS, 2510, or the 2530s.

I would like a quicker power band than stock, so I was thinking of going to a 9:1 with the GT-SS. I hate lag.

Thanks for any info you could give me.

Hmmm....sounds bloody interesting.

I reckon your plan sounds good, with the addition of cam gears and a nice free flowing exhaust including front pipes, you should be able to spool up a fair bit earlier.

I'd be interested to hear how you go.

[Skylineusa]

To me when it comes down to who is the fastest in the 1/4, its who has the deepest pockets. My pockets are kind of shallow, so when I take a hit off of the "Go Fast Crack Pipe" a have to look at it a little differently. I want power for a street car, power that will be there without having to rev it to the moon.

1st thing is increase comp, that has and always will be the easiest way to increase power, of course you have to look at the problems of detonation, but if you are only boosting to 1.1-1.2 and using a higher octane fuel, with a good tune. I see no issue.

Second is get a turbo that suits your engine. The 2.6 is a fairly small engine, yes it can rev very high, but that induces other issues of longevity. I really cannot see me revving past 7500, ever. Any more than that you are running a risk of something letting go.

I know the 2530 has been a proven turbo for the RB26, but I think it might push too much volume for the application that I am think about, plus the from the limited info that I have been able to read about the GT-SS will spool a little faster, plus with the slight increase of compression it should be at full spool pretty early in the rpm band.

I would have a good look at the Trust T517Z's, they are a great alternative albeit without ball bearing Turbos and water cooling. Ive read plent of reports that indicate they spool at about the same time as 2530's but with the power of 2540's.

I have encountered more setbacks than I care to recount.

Starting with an ever-growing modlist, which in turn leads to buying the new parts, which in turn leads to unreliable sources, or unavailable parts.

I should have rods and pistons by mid-May, when the car is going in for the work...

This is dragging on way too long and it's frustrating the hell out of me

Sorry I can't show you any dyno sheets just yet

Sorry to hear about your set backs.

I might just be the same boat as you here in a few months. If we start bailing water now, we just might make it:)

I hope to have mine up and running before the summer is over. I'll post my results for you guys.

[GiJOr33]

yes... set backs are the bain of engine building. A lot of it on supply of parts. You can wait 2 months for some rod bolts only to find they sent you the wrong ones and you have to wait another 3 months for more to be made and sent from the USA.

For anyone modifying a car (to *your* specs as opposed to what your workshop can get their hands on) - this behaviour is fairly normal. (sorry Merli) But I just wanted to point out to everyone the 'cons' of modifying your car.

One thing leads to another hey mate

[GiJOr33]

exactly... i think if you are building a specific engine it's a good idea to buy a second engine and build that up so that you can still drive your car. Then once the engine build is finished you can pull out your current working engine and fit the new one. Then you just sell your complete engine to get your money back on the initial purchase of the one you just built up!

No need to be sorry, you're absolutely right... But that doesn't make it any less frustrating!!

re: second engine, once I have all the parts ready to go and to give to the engine builder, it shouldn't take more than 2-3 weeks for them to do the rebuild. All they have to do is a full strip and rebuild from the ground up of an engine (but with all new goodies ) so it shouldn't take too long. Builds only stretch on and on when you order parts and wait for them to come during the actual build.

too right merli cant wait for hte results as well should be great

Hey Merli

Did you end up getting your engine together? did the GT-SS bolt straight on???

[Merli]

Car goes in on Saturday for the build

And yes, GT-SS turbos are straight bolt-ons... I'm only building the engine for reliability for circuit racing, not to hold the power... Stock internals should be fine.

I should have results for you within the month :)

[Jimbo2000]

who got the contract so to speak?

[ferni]

So your not doing forgies now?

[Merli]

Due to the nature of the automotive industry, and the backstabbing that goes on from workshop to workshop, I won't divulge that publically, in case I want to take my car to other workshops in the future to get some work done.

I'm doing everything shy of a stroker kit.

I was just saying that what I'm doing isn't necessary, and won't add any power... GT-SS turbos can be used on a stock engine just fine.

Your doing it because you want to run NOS right?

Yes that, and I want the reliability of forged internals for the circuit racing I will be doing...

I'm also a firm believer of "doing it right the first time"
