Hypergear Turbochargers and High flow Services Development thread

[zebra]

I had one problem with mine. Was told by stao the water feeds on the turbo were 14x1.5 so wasted nearly $50 on speed flow fittings

Rest was fine. Was a atrg3 .82

So should everyone be checking the clearance between the dump and aircon pipe? So if there is not atleast say, 30mm clearance (5 bolt exhaust flange has an extra 25mm over stock now) , then you need a different dump pipe. Is this correct?

Mine had a little bit of clearance (~20mm) which i didn't notice. Ended up frying the tube lol.

[Harey]

Harey - there is nothing wrong with my install, unless you want to blame me for a ring not holding compression. I will have an engine in and dynod before Christmas if I can.

Except for dodgy boost signal and you running 25psi when it was tuned to less than 20psi?? The better the turbo the worse damage you will do from running way above tuned boost levels!

[Rolls]

dont you guys have jobs and work to do instead of bickering on here? : p

[lilcrash]

In no way do I doubt other people results, I'm just disappointed at the recommendations(not just about hypergear)I have received considering how things have gone, honestly I think I received a faulty actuator, and I still don't feel that any damage was done by myself, it looks more like the engine was never run in in Japan.

[chocco]

lol now you blame some1 in Japan for your engine failure?

Do you go to autobarn and ask for 710 fluid?

[lilcrash]

No just considering there is no damage just low compression, either the ring had never bed in or it just wore out. And considering the rest are fine it makes more sense that it didn't be in.

[GTScotT]

Good to know I'm not the only one. The way my install went I think having a known turbo (garret/hks) is worth the extra few dollars, fair enough I am yet to see if the hypergear can actually make any power but before Christmas I will have all the information/dyno sheets to know if stao will be receiving my turbo back.

cool, so I guess you think everyone that rushed out and bought GT30s back when the write up hit SAU returned their the turbo if they didn't get 300kw?

That was the aim of that turbo on the RB25, yet if you look at real world results there is a 250kw result for every 300kw result with seemingly the same effort applied. In your eyes I guess they should all get refunds!

I should blame a supplier for my blown SR, it was running tuned for 7 years then the day I put on their catback it blew! Those assholes sold me a faulty pipe. Sound funny? Actually its exactly what happened to you. I put something on my car and thrashed it while it wasn't tuned for it. Boost spiked, it went way harder, god knows what else, and cost me a healthy motor. My faux pas as I didn't think a simple catback would throw the tune out that much. On my life one lap around the block, pop.

Its no hero story, just consider it though. Its entirely relevant to your case, ive read all your posts, including those when ur motor was untuned in the stages area.

[lilcrash]

I didn't mean for a refund, I would just like him to have a look and see what's going on.

Yes I drove my car around with a 3500rpm red line for a few weeks, I didnt think it was that big an issue, clearly Nissan motors aren't as strong as the Toyota engines I'm use to owning.

[zebra]

you couldn't source a proper boost feed for the actuator..but you are qualified to say there is no damage? 2 days ago you couldn't get the head off, a few weeks ago you thrashed a motor tuned for 14psi when you were running 25psi......but it is Nissan's fault?

why does anyone help this idiot?

[lilcrash]

1. Nothing wrong with where I had the boost feed, people had suggested getting a boost feed from the manifold . That is stupid.

2. Sorry for not seeing an invisible bolt.

3. Tuned for 22psi dropping to 14, so the 3/4 psi spike isn't a big issue in my point of view. I wasn't holding it wot to redline, was just creeping it to see if boost was holding.

4. I drove an untuned 35year old turbo celica with a 7psi boost increase for 4 years and never had a single problem.

[GeorgesR34]

Reading your steage section posts you've mentioned that you were chasing a RS4 GTR Stega with new turbo fitted and "just" got beaten. I'm suspecting you've blew your motor long before it got on the dyno, and the dyno tune plus all the threasing after just hurt it more.

Thats the thing about forums... Cant delete your old posts

This post sums up exactly how little you know about cars and how far you should stay away from them.

[hypergear]

Well no one can fix up yesterday. He's main objective is getting his engine back together soon as possible. Below is what I've done building my test rig, follow that you should have a very solid engine with out spending heaps of cash:

I've rang around for the best prices on all parts I got:

1. CP pistons 0.5mm over sized from CJmotors

2. ACL bearings, ARP head studs, and full gasket set from MD spares.

I've paid about $1500.

Find a good engine re-bore service locally, get them to bath your engine block, re-bore your cycs refer to piston specifications, fit pistons and crank together as a short engine.

I've paid $650

If you are technically minded from there you can assemble it your self (mmmm not good idea). Or take it to a trust worthy workshop to have it assembled and dropped in.

I've paid $1000

So all up my rebuild cost just under $3200 and its been holding together well since. If you wish going slightly bigger in turbo I can help you getting that done free.

^ Hypergear always keeping it cool and willing to help you out.

You can't blame hypergear, you can't blame Nissan. You can't blame anyone. Your luck seems low. That option up there sounds pretty good. It really isn't hard to bolt the head back on and reassemble everything. Torque settings, set the cams, set the pistons, slap on the head, torque it up, manifolds, gaskets, studs, nuts, wiring, injectors, plenum, spark plugs, coils, turbo and your just about there!

Then again alot of guys here are blaming you for running 25psi. 25 psi will cause detonation but it isn't likely that one or two runs on this will KILL the motor.

Like I said in many other posts, if that cylinder bore is in good shape, replace that damn piston with a stockie and put it back together.

[dori34]

No worth all the effort just to replace one faulty piston sarge, he might as well whack in a fresh set of forgies.

[DVS JEZ]

If there is no damage from detonation, pre ignition or lean out then chances are the 25 psi wasnt the issue for the motor. But without inspecting the engine i cant say for sure.

I can tell everyone is getting annoyed with littlecrash, but please don't start name calling,

Lilcrash have u started the rebuild process for ur motor yet.

[DVS JEZ]

No worth all the effort just to replace one faulty piston sarge, he might as well whack in a fresh set of forgies.

Please dont ever rebuild a stock motor with another 2nd hand piston.

[Rolls]

Cheaper option would be to buy a second hand motor in known condition. You know it won't fall apart from poor workman ship like some rebuilds will, they have a proven track record and will hold 250-300 for many years if tuned correctly and never see detonation and are kept cool.

Honestly I would do that, you can get a s1/2 rb25 for $1000 if you look around, I personally sold a forged rb25 short motor for $1k with only 7000kms on it. Or you could fork out for a neo for around $2k which has some advantages, better head, better rods, newer with less kms.
