Stagea Performance Upgrades & Power Results

[FAkbari]

First of all, this is a discussion around understanding the potential differences between Stagea's and Skylines, to understand why there may be less power achieved whilst having similar mods rather an expectations.

Secondly, it is also to discuss and understand the differences between using different qualities of products and results achieved, as some people have reliably achieved good performance gains from using less superior products and parts. This is not to mention that everyone has different build/upgrade budgets and its a means of determining whats myth and fact.

Thirdly, I'm not sure what the relevance of your post really is besides trying to be sarcastic, which seems to be the common traits of most keyboard warriors on this site and forum. If you don't have anything relevant or useful to say keep your heroic bullshit to yourself as its a waste of everyone's time. I would have thought that the whole point of this site is to get enthusiast together to constructively talk about a common interest in cars etc.

By putting that post up, what were you really trying to achieve other than wasting 5 mins of your time being a keyboard warrior, rather than trying to provide some constructive feedback/advice????

Seriously...

No need,

Thank you or filling my quota of LOLs for the day.

M35 Stagea

Just fitted Denso 570's and E-manage.

Previous mods include : Scotty dump, Legalis R exhaust, AMPerformance intake, ATP High flow and Greddy FV BOV

219 kw at 16psi.

Whilst that was pretty much my goal, top end power wasn't important to me.

I was hoping to run over 20 psi but stock intercooler appears to be inadequate.

High air temps and high risk of DET so tuned back for safety.

Previosly had a boost-t in place as there was massive boost creep with the factory solenoid.

Probably due to the 1mm restrictor in the vac line, which I discovered later.

My Turbosmart boost-t was stuck out the whole time I had it fitted and didn't even realise. It didn't turn anti anymore whilst the plunger was out 15mm.

Was hitting boost cut.

Currently running straight of Scottys actuator spring, holds 16 psi nicely. No boost controller at all.

So overall, can runs nicely but a bit disappointed in low down accelleration.

Car went harder pretune with stock injectors.

So hoping HDI GT2 Pro will make the difference, then back on the dyno.

Stock turbo still?

[scotty nm35]

If the car felt stronger pre-tune, then Jez likely took timing out of the midrange. Most tuners will do that to protect the engine, these VQ's run a lot of timing off boost, and it's hard to talk a tuner into leaving the timing in there.

[conan7772]

So after new intercooler and changing boost from 16 to 20 , car feels great.

Powerful smooth accelleration.

Still have a slight rumble on idle, tbc

219 to 237 kw.

ATP high flow still hangin in there- slight whine - suspect minor shaft warpage on a boost cut pre tune.

Good result! (Please turn chart right way up in future - bad for my neck...)

can you please provide a breakdown of mods done to achieve what you've got there?

I have a series 2 auto and am looking to get around the same numbers, so would be interested to see what is required to get in that ball park.

[KiwiRS4T]

The info is on the second chart:  Nistune chip, Z32 afm, 3in exhaust, stock manifolds, GTX36/71 and E85 fuel but it looks like still with SMIC.

I would suggest for you Nistune chip, Z32 AFM, suitable Hypergear turbo, 3in exhaust, FMIC and ID1000 or 750 injectors (I know the injectors look too big but these modern injectors will work well at low duty cycles).

To quote admS15:

Hypergear highflowed stock turbo will give you a bit more and will hold boost better up top and is direct bolt on. Power does tail off around 6500rpm but can make around 250-260rwkw and costs around $900.  Only negative thing about it is its journal bearing. Still works good. I have one, made 260kw on 98 and 312 on e85.

[DaveBb]

it is FMIC on those dyno pulls , SMIC wrong on print out , also runs forged pistons , big injectors , nitto 1.8mm head gasket  , ARP rods & studs on the head , previous owner got 248 awkw . has a high stall & shift kit also ... ( my numbers a bit low turns out a sneaky coolant leak into #5 from water gallery past head gasket issue had occurred took awhile to find that . head gasket lasted 10000kms  KiwiRS4T comments re injectors spot on. cheers

Thanks gents,gives me a clearer picture of what i need to do, and less trial and error to allow figures to be achieved comfortably
