I'm getting a new engine and manual box put in my Z and want to get some serious power at the same time.

What level of boost will I be running to get 500bhp?

How high can you go on stock internals? 550 ish I've heard?

 

Which turbos? Like the look of GT25's or PE1420's?

Nismo 555's?

Dual intake with single MAF and modded chip?

Which chip?

Which plugs? Had some HKS ones in but suspect they will be in a bad way if it's been detting a lot?

I presume I'll need dump valves and metal hard pipes.

 

What else will I be needing?

I've got big intercoolers, single Blitz SUS intake, full stainless decat zorst, Blitz boost controller.

 

As I'll be needing a gasket set anyway is it cheaper to buy forged pistons and rods and rebuild my old engine instead of spending cash on a new one?

My current engine has probable head gasket failure, rear oil leak and sounds like a con-rod broke.

I've just had my engine rebuilt. From memory

 

Ross forged pistons

Nismo metal head gaskets

2 big ass roller bearing hybrid turbos

fse motorsport fuel pump

fse power boost valve

pace intercoolers

new valves (cos the old ones were shagged)

ring gear(also shagged)

cam pulley & belt (and this)

det sensor & loom(and this too!)

 

Probably loads of other stuff I've forgotten.

It came to around 8.5k:eek:

 

All that was added to

 

Apexi AVCR- your blitz controller should do the job

Apexi SAFC-controls fuelling bypassing the need for a seperate ECU upgrade

AP racing metal plate clutch-cos it eat the standard one after the Apexi stuff was fitted

HKS Super drager exhaust

HKS Super powerflow induction

HKS super sequential dumpvalves

 

The car is now running at 1.4 bar of boost and should be hopefully be getting to the 450-500 bhp atw mark

:)

 

I didnt replace my rods cos the standard ones are forged anyway, but if you've broken one and want to upgrade I know crower make a set as do Jun.

 

Hope this has been of some help

adam, did u get someone local to do the work or did u do it yourself? was just wondering who youre using around here.

I use DPmotorsport in Warrington

sounds awesome\? but to go 400 on the wheels i think the two most important units would be A: what type of turbos you have? B: a single intake on a single MAF would not be enough to flow 500wheel horespower no matter what you did as the voltage on the maf maxes out at 5.174 volts i think? which equates to around 460-470 bhp.

so what type of ECU and injectors and intake are you running?

No idea whatsoever!! , they came from universal turbos and apparently there usual application is for 200sxS14 upgrades.They had to be reengineered to fit the 300's dump pipe and oil feed.

Size wise they were pretty big-possibly T3 sized(?) I know S14's come with T 28's and these were defo bigger.

Currently Ive just got an HKS super powerflow - when funds allow ideally I'd like to get another air flow meter and bang another kit on that aswell, either another HKS or 2 Apex'i's, but as I've just spent a ton of money on the bastard I'm a bit skint at the moment!

 

 

so what type of ECU and injectors and intake are you running?

 

Stock ECU- the boost is looked afterby an Apex'i AVC-R and the fuelling by an Apex'i S-AFC.

Injectors are standard at the mo cos I ran out of money but I'm running an uprated fuel pump and an FSE powerboost valve to increase the fuelling until I can afford my 750cc injectors

 

dammit my typing finger hurts now:p

Oops quote insert didnt work exactly as I'd planned:rolleyes:

with stock injectors and stock ecu, there is no way youll go near 400 wheel bhp let alone 500bhp. what you should do is dyno it first before yuo do injectors ect and how are you going to map injectors with stock ecu?

So what turbo's should I be looking at that are capable of 600bhp?

Been looking at GT25's and PE1420's

Any others that are a bit more friendly on the already pissed off bank manager? :D

Chris the PE1420S are awesome blowers, should make around 500 on the back wheels, they came out a little short on the HKS gt2530s at the top end(i think the most soemone has made is 570 whp ogt 2530s, the GT25BB are aslo great but i think they max out around 450 on the wheels from what i have seen.

The JWT 535 bb turbos made around 480 wheel horespower. Sport 500s made around 440 wheel horespower. TD05-18G or 16G should go way above 600 whp, Pentroof PE1820S would be good for 600 whp but youd need pentroof manifolds for iether fo the last two.

 

There is one above the gt25bb that would be good for 500-550 aswell.

(this is all i know of that have made the figures so far)

I would go for PE1420S as its a true bolt on turbo kit and will make more power than you would be able to use at 20 psi.

Wait and see what duffers PE 1420's are like. Rumour is it might make an appearance this year ;) . The ultimate power and streetability setup is the TD05 turbos without a doubt but remember the stock manifold is crap and you really want the pentroof manifolds with those and they are not cheap. Single intake and stock injectors will never flow enough fuel/air to make 500hp, you willl have to go dual pop and bigger injectors. You could possibly squeeze a little more from stock injectors by raising the fuel pressure but this wont be enough for what your looking for.

I think duffers got some 555's to go in as well so that should be very interesting when its done.

Always makes me laugh when you hear the cruise boys babbling on about how so and so's cossie is "chipped to 500 brake" etc, 99% of them have never even seen a GENUINE 500bhp car LOL.

Yep :D Gimme a couple of weeks and we'll see - although stock clutch so bugger :rolleyes: Now where's that credit card gone....

it arrived on my door this morning lmao :D

I think the way I'm going to go is to get my new engine in with the big turbo's on, then in a few months time I can easily put the injectors and dual intake on for some serious fun.

Thats exactly what I did chris! Except the upper idler bolt shearing just brought the next stage 10 miles after the initial rebuild LOL

"LOL" ??? thats the spirit Duffer!

So where do I get a pair of PE1420's from?

I've tried a few searches and only seem to find the manufacturer in Japan.

Do they have any dealers?

http://www.ginnmotorsports.com would be a start....

 

http://www.zedparts.com used to do them but I think they no longer do..

 

HTH

 

CheerZ,

Like I said an Apex'i S-AFC controls the fuelling.

 

On the subject of airflow I was talking to the guy at the garage, and he said they've been using 300zx airflow meters in GTI-R's to run over 400bhp

yeah and no offense but they are talking crap then.

The Apexi S-AFC can only adjust the fueeling on your stock ecus fuel maps ? so your limited there, you still need to go onto a modified ecu or a stand alone unit.

 

The MAF or air flow metre can do more then 400bhp but you will effectivly need two to run 500 WHP let alone 45whp.

one is just not sufficient. (this is a proven fact)

An Apexi S-AFR will nto control idle and injector duty cylce on Larger injectors (you need to get a unit that can or an updated ECU) and stock injectors will max out far far before 450 wheel BHP.

 

Have you done a dyno yet? or will you do one? im pretty willing to bet you wont go near 450 bhp on the set up you have no matter how big your turbos are,. your engine will expire long before you reach that figure.

The car is getting dynoed in the next two weeks hopefully.

I know I need bigger injectors - I've never denied this - thats why I'm saving up for my 750cc's. But as an interim measure an FPR has gone on to increase the fuelling.

 

On the subject of the SAFC the guys at the garage seem to think its up to the job. I dont know- I just drive the thing!

I guess the only way to find out is to wait til I pay a bit more off my credit card bill (cos I maxed it doing the rebuild) and get my 750 cc injectors fitted!

Hmmm.... sounds to me like you think I'm all talk and no trousers:mad:

 

Just to set the record straight I've not got 2 bank loans and a maxed out credit card and a vast f**kin overdraft to end up with a slow car!!!!

 

If I have to get a different ecu or another afm its not the end of the world - its a problem - it gets solved. I'm so far in debt now another 1 or 2k is going to make f**k all difference.

 

If you think the garage is talking crap then its probably me being a weak link in communications cos they've always given me good service (a valuable commodity going by whats said on here) and I've seen/ been in some of the cars they've built and they are rapid!

 

When I answered Chris's initial thread I was'nt saying "I have 500hp do exactly as i have and you can too" , I was trying to say "here's what I've done - hope it gives you some ideas".

 

 

Rant over - feel much better now;)

im not saying that at all, like i said it sounds awesome, but im just simply pointing out that you are going to be dissapointed or something is going to go wrong as you havent got the goods to make that sort of power.

It woudl be great to see a dyno sheet with figures your going to claim without modding the ecu and other bits, (it would save us all a fortune :D)

but 450-500 whp not crank BHp because thats pointless - anyone can project how much power they lose through drivtrain loss ect.

What youve done sounds awesome.

What turbos are on there?

Oh Waz, stop winding the poor guy up.. :D Only kidding.. You have valid points, my SA friend..

 

Adam,

 

AFAIK, an AVC-R will only allow a 20% fuelling adjustment - which means once you fit the 720cc injectors, you're well outside that range.. Now it could be that they are actually going to, for example, fit the 720cc injectors and a unichip, or some other fuelling dongle to alter the injector pulsewidth so that the stock ECU can manage the injectors - a Greddy emanage & e-01 setup could do that, FWIW.

 

The whole MAF issue - could also be that they're planning on swopping you to a MAP sensor, if they are fitting an aftermarket fuelling & ignition system.. Hard to say without talking to the people at the shop themselves - but, what Warren says is true, a signle MAF will run out of puff at about 450bhp, because, basically, it can no longer measure the volume of air that you're drawing into the engine..

 

Anyway, I'm sure Warren isn't really trying to say you're all mouth and no trousers Adam, he's just worried about losing his 'most bhp' crown ;) :D :D

 

Sorry - I'll stop winding him up - I'm sure he just doesn't want to see you go down the same route he did (i.e. several engine rebuilds.. coz that gets expensive, even to a rich South African ;) )
