Hello!

Im planning to buy a turbo kit for my R33 GTR from Powerhouse Racing

My internals are simple HKS 2.8L Stroker with bearings, ARP rods, new greddt headgasket

Will it hold för 600-700whp?

Well i was going for the T88 but on the PHR site i found 2 other turbo kits t78-t88 and a new one called TD05.

So as i said im looking for a turbo that can handle 700hp but i will probably go for 650whp or something like that.

Will my engine hold? and do i need to spend much more for a good engine?

T04Z and 2 bar of boost will get you there.

I heard thats a good turbo, Will my engine hold? I am gonna leave the engine for some inspection but i want to know what you guys say.

Thanks for the fast answer!

If the engine was properly assembled and balanced, and its tuned properly, you should have no problem sustaining the sort of power levels you are talking about provided you select the right turbo and have all the supporting fuel/cooling/oiling systems in place.

thats the same set-up as me 2.8L TO4Z .84 garret 710awhp, is absolutely nuts :) scared the shit out of a few mates..

also considering the GT4088R check that out, I went the TO4 because is was tried and proved, plenty of dyno results to look at..

Oh nice mate, Can you put up some dyno results? You drive the car on the weekends or every day?

Will your engine hold? dont bet on it, and for how long, many have failed.

Good luck, I hope it works out.

It wont fail if you have a good tune i knew a guy wich had 600hp on stock engine he started the car a year ago and its still running, He had an awsome tuner.

Not trying to put you off but there's not much info in your threads, 2 bar, 650 to 700hp is a lot of strain and mumbo! how many kms on the engine, who built it, how much work has it done? The tune is one thing but the engine clearances, tolerances and ware is another thing on an already built engine.

The last time I had my engine inspected it involved pulling the engine out and inspecting a big end bearing, sadly they were all f#$&ed after 2000kms.

Hopefully all goes well, but asking if your engine will hold is like asking how longs a piece of stringl. Good luck!

Its the last post in the RB26 dyno results.. not a daily but more than just weekends..

as for will it last, yeah how long is a piece of string, you see some guys putting a lot through stock engines and others breaking built ones ??

you would hope if they have gone to the trouble and expense of the stroker it would be done properly..

no point living life thinking what if ..

just take it up slowly and see if anything comes up (or out) :P

22-24psi should see you around 600whp

No point living life thinking what if.. But definitley worth considering, my comments are based on the guy having made only 12 post and having asked the question more than once if the engine will last, having an already built engine (God knows who built it or what its been through), I suspect he is new to the wonderfull world of GTR's so just some words of caution.

"You see some guys putting a lot through stock engines and others breaking new ones" This is very true. (without rubbishing any engine builders)

Based on the limited information 2 bar would be risky without knowing more, maybe the straw that breaks the camels back, I've had 4 engines in my car (pisses me right off) and used to run 25psi with tomei cams, motec, 2871-10 turbos and many other goodies, these days I run 20psi, smaller turbos, std cams shafts and have never looked back. (my choice only)

22-24psi sounds more realistic, 600whp, still bloody fast.

Well yeah im new to GTRs and the engine is Built by MGT Racing before it reached me in Sweden, I put on some GT-RS turbos and i had the car for 4 months now and run 500hp with no problem at all MGT said that the car was built to do more than that and GT-RS turbos was nothing for it, And ive had 700hp volvos before so im not new into engines and i can handle a car at 700hp.

I leave the engine for inspection tomorrow to one of Swedens best tuners/engine builders lets see what they say

Oh, i forgot to say its an N1 block :)

btw i came in to the forums this year and i barley used it you cant judge me buy looking at my posts.

yeah,, I had it tuned before on a rear wheel dyno only weeks before, and made 550rwhp , then on the awhp hub dyno only made 520awhp, on the same tune...

after retune made 710awhp ,,

was hitting boost cut on cool nights @28psi . so have pulled the boost back 1.5psi so maybe 680awhp (on a hub) what ever that is? is it a percentage less??

      My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered

      No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
