Recommend Me An Upgrade...

[nsanity]

So I have a Skyline and its not feeling quite as perky as she used to.

I'm thinking about pouring about 10k into it. In that 10k is 1k of Stereo and 2k of Suspension (SK's Springs, Bilsteins, Sway bars) . Leaving about 7k on gofast bits/install/tune.

Current mods are as follows...

FMIC

PFC

AVC-R

Bosch 040

3inch turbo-back exhaust.

I've sorta decided I want a new turbo - as the people who are going to do the work tend to think that its a lot more reliable at getting good figures (he felt that whilst sometimes you get good results out of hi-flows, othertimes not so as much as he'd expect) - also, the engine has 110k on it, which means that poor stock turbo has been huffing a bit more boost than it should have for at least 35k of those.

Restrictions?

* Stock-Airbox (although I am quite keen on getting a CAI box setup of some description...), I really don't want a pod and If it can stay in the Stock-Airbox, all the better.

* Staying internally gated

What I want?

Currently (before I took the Pod off) I was getting ~200rwkw at 15psi. I want more (duh), but It also has to be on the responsive side of power. I don't want something that doesn't start because its too cold, is unbearable off-boost etc. My missus drives this to work 5 days a week, and I do the long trips/weekends .

I am sorta keen on a set of Cam's to go with the mods (injector's, turbo+bits to make it fit, Z32, CAI mod) as the old V8 guy in me thinks it will aid in making sure things are a bit more responsive - am I right in this belief?

I've had a poke around and people seem to be making ~270-300 rwkw with this kind of setup, with graph's that look quite sporty between 4200-6700 rpm.

stronger clutch

z32

hks 2835 pro 0.87

injectors

and tune it

[nsanity]

stronger clutch

I have the Exedy HD one... more than that?

Also, the tune is certainly part of it.

[paulr33]

should be ok, no need for cams

should be ok, no need for cams

In what respect? Is there nothing to be gained (particularly mid-range) or is it a marginal upgrade in terms of final power figures?

[NYTSKY]

HKS T51R SPL.....I love these threads.

[33drifter]

HKS GTRS turbo, strait bolt on, internally gated.

Injectors

Aftermarket panel air filter

I have similar mods to you aswell as what i have listed and am getting around 275rwkw, my next move is cams

That's because you don't read his requirements and post up shit!

I would go with what PaulR33 advised, would be a good package to meet your requirements, with acceptable response. If you have the money, get a set of Tomei Poncams and while you have the head open fit some Tomei valve springs. While you have it almost all apart, a quick reco/freshen-up of the head may not go a stray (valve stem seals, etc)

Cams will definitely help mid to high rpm range, but are not necessary to make good power. They will make less power in the low rpm range, but is hardly noticable.

So a shopping list consisting of

HKS Turbo Kit - GT Sports Pro (Nissan - Skyline - ECR33/ER34 - GT2835 Pro S - A/R 0.68)

Tomei Air Flow Meter - Z32 (Air Flow Meter Z32)

Tomei Pon Camshafts (ECR33 Series 1 (RB25DET) - Duration: IN,EX 256 Lift: IN,EX 8.5mm)

Tomei Valve Springs (Nissan - Skyline - ECR33 - RB25DET - Type A - Lift 8.80)

Nismo High Performance Injectors - Yellow - 555cc

or thereabouts would do wonders? I notice the A/R on the HKS kit is lower compared to Paul's recommendation...

I assume I'll need some alternate manifolds, or are the 2835's a straight swap?

The reason for my response was the fact that there are about 10 of these threads per day. Searching is one of if not the best way to get an answer as subjects like this have been covered time and time and time again.

To the moderators , is it worth having a small number example builds and graphs - sort of along the lines of what a typical Skyline owners opts for and post them up in a separeate section ? I know this overlaps with the turbo results section but just a suggestion . Might give the new punters an idea of what to expect ?

So you are getting 275 rwkw with the standard air box?

To SAU Mods:

+1 Like "N1GTR's RB26 rebuild" thread, or "Birth of an RB25" thread. They were great reads.

What if there is a new subsection titled "Engine builds" for example, with subsections within it for different engines, and another series of subsections for different power brackets OR stages (std engine/forged engine/race engine) OR turbo choices. Will save lots of leg work for heaps of people.

It could be like the engine upgrade section BUT can be more in-depth, with pictures and open discussion (unlike the no chit-chat policy ).

All this needs is approval- and donators willing to give their time to create the threads

I like this one... That will get you response, lots more power, and probably save you money.

Make sure its the GTRS turbo kit though.

[eddieeeee-ro]

what is the standard airbox with a high flow apexi filter restricted at?

i was hoping to make 250rwkws with the airbox ?

Definitely go a larger A/R as paul recommended. I don't think the one you posted would be too street friendly.

For your suspension have you looked into any of the Jap coilovers? I was going to SK suspension but have now opted for a HKS coilover from doing a search and recommendations of people who have been in and driven cars with those coilovers but then that also depends what you're looking for in your suspension...

[SmashBoxx]

injectors, coilpacks, high flow filter and all the basics and then bigger turbo..

The comfort side of performance. I don't lower my car's - speed humps exist and you have to deal with them

Everything I've ever read has said that Jap Coilovers are built for roads that aren't in Australia - you know those smooth and maintained ones

I used to be in Canberra (now Melb) and every other month someone was selling their Tein's or what have you to pay for their chiropractor.

[race_snooze]

breaks, suspension!!

[TTT]

breaks, suspension!!

who does?

using bare hands?

anyway, nsanity sounds like you have your head on straight and "kinda" know what you are after and what you will need.

This is one of the BETTER "what mods should I do" threads

I agree with the new section.

kinda like a "readers rides" but more so a members builds.

make it so anyone can create a thread, maybe provide a template for car, engine, mods.

then only the thread started can update.

anyone who wants to ask quesitons can PM the person.

that way you get no chit chat, and you have a full diary/blog type thread of each member is doing/has done to their automobile.

I am yet to read a better thread than Godzilla32's "My restoration" thread.

And that is stickied in the general maintenance section.

surely it needs to go in the POOL ROOM..

and that there is what the new section should be called.
