The rebuild to create a monster is now on it way so heres a few pics of the story so far:D

 

I dont know if you noticed but the car actually floats :D

 

Theres f***ing bits everywhere and just when you think youve taken all the hoses off you find twenty more :confused:

 

But the engine is ready to be lifted first thing tomorrow.

 

Cheers

I am of the same philosophy as stu - i am running stage 2-3 T28 hybrids with stock internals at 14psi. I already have an upgraded rad and intercoolers and i want to run at higher boost levels.

 

I quite expect my engine to go bang when i increase the boost but whats the harm in trying - if your fully committed to building a new engine anyway, why not see what the existing one can do?

I think the injectors max out at 16-17 psi though mate :eek:

 

Although I'm sure a troll will stop me if I'm talking total shite :rofl:

16-17 psi on stock turbos - before that on mine

 

p.s. nismo 555's being fitted on Monday :dance:

Well, looks like you are going to beat me to it then Alex :D.

 

Roll on 600 BHP ;)

Just out of interest, where did the 600 bhp figure come from? It sounds like an extremely large amount! I'm fully not expecting 600 bhp (crank) running T28s at 2 bar / forged pistons / cams / ported heads / big intercoolers / phatt exhausts (no cats) / ECU tuned by SE-Pete... not that I'm saying you *can't* with standard pistons. And it's not a "I'm better than you cos I've spent more money" - but there are reasons Pete configured my engine like this... the big one being because he knows what's gonna work. If you're up for the challenge of trying to find something new, then good on y'all. But (said in the nicest way possible) be ready for disappointment. I reckon there's some things that could help tho. Maybe a good place to start is chucking away the cr*ppy bits of the engine and making something better - like the exhaust manifolds and plenum?

I agree can the t28 even flow enough air to produce 600bhp?? personally i dont think so, when either iain or me get the 18g tubs it will be interesting to see the size difference between them. I think you have to do alot of mods to get 600bhp and not just the bolt on mods, lots of other stuff to help the flow etc.

 

But we shall see ;) only time will tell

Apparently one T28 (a real one, not hybrid) can make enough air for over 400 bhp - SE managed that on a GTiR. There's a Jap Performance article on their wall (by the comfy sofa) where they've had 470-odd on standard 300 bottom end. I thought that was a lot! Has anyone here even broken 500 bhp with standard pistons?! Real proof I mean, not "I've bought these bits so I've got 500 bhp".

 

Stu... don't get me wrong, but when your lump was in SE you didn't wanna fork out for extra bits like mig-wiring which could've helped hold it together. Now you're talking about pushing it til it breaks? It's not just piston damage - what happens if you f*ck the block and have to start again?

No Mike they can't FACT!

Would be a bloody miracle if A T28 did, but we ain't talking A T28 it's A PAIR of t28's, each one needs to flow 300 bhp, that's why SE favour them, standard ones won't, but modified hybrids of T28 as fitted to Pulsars have recorded over 300bhp, FACT

smithy :cool:

So Smithy are you saying that a Z fitted with a pair of T28 hybrids will make over 600bhp?

What's going on here? Is this whole thread a wind-up that I've been left out of? Am I talking to myself? 300 bhp Pulsars?! I've already said SE have had 400+ using one T28! Then Macca says a pair of T28s can't blow for 600 bhp (fact?!)?! You'd better let Pete know next time you're down here Iain cos he might need to stop working on a few other projects if that's the case.

 

Gotta ask - what is this "1st two UK 600 bhp Z's" teaser? It's a trick question, right? Because the obvious answer is SE. Or did someone do it before them? 1st two 700+ bhp UK Z's has to be SE too. No? Correct me!

 

This whole bhp thing seems to be getting out of hand. I wouldn't want a 600 bhp Z, because to get that poor ole V6 to make that much power you'd have to push everything right up to the top rpms (cam timing, turbos coming on full boost) which means you'd big-time be losing out low down. I wanted a car that I can actually drive! If you're racing your 300 then fair enough - go for max bhp and drive it around peak rpms... but that's not exactly public-road now is it?! If you guys are going for a peak bhp p*ssing competition then I'm really not in it, but I reckon I'll still have a quicker car overall because I'll have power I can use rather than masses of lag then tyres of fire.

NOW HEY!

 

Listen hear matey!:slap: ;)

 

1 I have asked Peter about this and this was his answer................

 

Will STRUGGLE to make 550 with a pair of T28s!

 

2 The 700hp Z that you are on about did NOT have T28s fitted:rolleyes::slap:

He will need a new block,worst case could be a complete demolition of the whole engine!:cry:

OK, so they won't let you pay for a guaranteed job to make 600 bhp with a pair of these... but when they get 600+ that's a lucky customer who wasn't expecting it(?!). Not disputing what you've been told but lines between the reading of...

The 700hp Z that you are on about did NOT have T28s fitted

NOW HEY!... I never said it did! :) And I kinda was thinking there's more than one. But anyway, my point was that SE have done 600+, 700+... so what's the "UK's 1st two 600 bhp Z's" teaser all about? Honestly, I just wanna know... I h'aint disputing how far anyone can p*ss up the side of a wall.

"But anyway, my point was that SE have done 600+, 700+"

 

Where are these cars because the only one i have heard of is Andy's "600zxr" which never runs!! is there any others?? again you can say mines got 500 600 700 bhp what ever but you are right thats just a p1ssing contest what i'm after and i'm pretty sure its what iain's after as well is a car which is strong enough to use regularly is driveble. If it produces 600+ they i would be very happy bunny if it doesnt then i've still got a car which will have mega bhp and more importantly doesnt blow up!! we all want different things from our zeds, i'm not after the "fastest" or "most powerful" but if i achieve it great but also lets share the knowledge then other people can get there too. :D

 

Kirbz

:rofl: this thread is a very amusing and interesting read.

 

To be honest, for those of you that are getting forged pistons, then fair game this is the way to go.

Obviously this is the less risk option because the forged pistons are much stronger than the stock pistons no one can argue that.

 

I'll leave the big engine builds to you guys, because I'm happy with my 400ish bhp (well I hope it's near that mark, well find out at Thor).

 

I'm currently talking to a few guys in the states, one of them is trying to tell me that 650RWHP on Stock pistons is the max which is a little under 750HP. Whether you guys believe that or not (not sure I do but more research and proof - i.e. engines still ok running that BHP after a year - is still being collected).

 

I know I'm not going to get 600BHP form bolt on tub's and improved cooling and fuelling, obviously there's much more to it than that, and I'm sure that if I do need to open up the block then yes I may as well change the pistons, but until I do need to open the block, there are staying in there.

 

You never know this time next year I may just sell up and buy and R34 Vspec ;). :dance:

I also just want to say.

Well Done and Good luck to those who own and are building 500+BHP cars :bow:

I think this is what the club needs. A few monsters to show the other cars what the 300zx has to say :D.

Hopefully we will see some of them ready for the GTO showdown.

Now listen here you perv!

 

If you want to go round pissing up walls in public,and seeing how high you can get then I don't want to know!:o

 

Lets stay on topic and just stick to Turbos and engine mods:rofl: :rofl: :rofl:

hi mike,

 

the t28 that SE use is the TB2808 - garretts official figures say that it is rated for 300 horses - twice that being 600 horses and the ratings are based on a 2 lite car.

 

this being true i dont see why twin TB2808's shouldnt be able to put out 600hp.

 

looking at the specs your 18g's put aout about 25% more air than a TB2808 - do you know what this works out to in bhp - surely to god it cant be pro rata because that would rate twin 18g's at 750 bhp omfg

 

i did notice though that the 18g doesnt reach peak efficiency until 5,000 rpm so it will be really interesting to see your torque curve and see how it translates into a 1/4 mile time.

 

I'm trying to achieve 450 bhp on my mega fast spooling TD turbos and i'm betting i wont be far behind you on the 1/4 mile. If I am, I will have lost and i'll just have to fork out for some bigger turbos.

 

Next year is going to be very interesting

:dance:

 

Regards,

H'oi! :D OK, I shall leave my p*ssing prowess out of it ;) This is an interesting thread, and I hope noones taking offense to anything I've said. Sounds like we all agree chucking bits at a car won't make it quick. Well, not as quick as setting it up properly or building it right from the start with a realistic figure in mind. Gotta also say good on kirbz for having the balls to take on the task... which is what the point of this thread was, right? I know my balls aint that big, which is why I went the (arguably) safer route and paid SE to do it! :) As for other cars they've done, there's a red one there right now that's (AFAIK) got the same spec I've got, except uprated con-rods, with T28's, that's put out over 600 bhp... this info came from Bob, so it's not me making it up. The other 700+ bhp one was the "pink" one that's been around for years. It was at their very first open day (at the new place) and there's been some pics of it about with a big "300ZX" sign over it, from when they took it to the Paris motor show. I dunno for sure if it ever really managed it, but it wouldn't take much to find out. Andy E's is as far as I know broke at the moment, but I can't comment any more than that. It is a monster, but it's also probably got a ton of gadgets it doesn't need.

 

I don't really like how easily this 600 bhp figure is being thrown about. A 400 bhp Z is a fickin' quick car and not to be sniffed at. I'd have said the mods between 400 and 500 bhp could cost a small fortune, but if you're careful and know what you're doing (mapping being a big part of it - which is obviously an art-form all on it's own!) it's possible without having to go nuts... uprated intercooler(s) / tubs / injectors / exhaust / induction / custom map. 500+ is something else. You must have to start making decisions about where you're gonna lose out... slap big tubs on and get loads of peak bhp but added lag... uprated cams - again, less torque low down til it all comes on song. Nitrous? Not everyone's cup'o'tea. 600+ is kinda beyond my comprehension! But it doesn't seem possible without mahoosive work and turning the car into an absolute sh*t to drive!

 

If money's no object then, sure... 600 bhp - why not?! The problem here is people thinking it's p*ss-easy to achieve it because someone else has got, say, 500. If this thread had no mention of bhp and kirbz had made a lump producing 450 bhp we'd all have been impressed. Maccas lump... being built and mapped by SE... with all their years of experience... it's obviously gonna be impressive. But Iain - you might hate driving a car that's all power up the top rpms, especially with an auto-box. Not trying to sew seeds of doubt, but big peak bhp doesn't necessarily make a quick car.

I'm putting T28's, 555's and a few other goodies on my Z with the new engine going in and really I just want a good years use out of the car to start with after all the time it's been off the road.

 

When I'm happy it's running well I'll start to up the boost and I'm hoping for 450 to 500hp on stock internals....

 

We'll see I suppose.

 

I think we need another poll:

 

Greddy tubs and forged pistons?

or

T28's and stock internals?

 

:rofl:
