Hi All

Just when I started to think I was a festering wart in the world of Skylines, here is a forum dedicated to Naturally Aspirated Lines. Thanks to Demon Dave for the Intro Link.

Well back in Feb 04, I bought my dream a 1998 R34-GT N/A Skyline, obviously I wanted a turbo but got a fantastic Part-ex on my old Max Power Car, but couldn’t raise the extra cash at the time to go for GTS. Since owning it, It certainly quick enough, I’ve taken out many a car that’s tried for example BMW M3 (I started to pull away at 105 mph), Porsche Carrera S 2, Honda S2000 (on the Fly), Toyota Supra (all show no go) and many others. (Agreed they could have all been rubbish drivers).

Anyway, I'm now excited about the prospect of having an ultra fast N/A Skyline, because it's different and there is not that many out there, well in UK anyway.

So my quest is to start modifying it… but in stages, with each month’s pay packet.

I'm now looking towards my future projects in the form of a shopping list of what should be the next mod, in order to get the power up to Turbo Figures; 300bhp +

So far I’ve fitted the following.

Engine; Now maybe 230bhp??

* HKS Air Induction

* HKS Iridium Plugs

* Blitz Nur’ Spec R Cat back straight through System

(Originally made for the GTS, GTT but once I modified the Cat replacement it was fine.)

It has a 80mm Boar, and is outputting a deep throaty sound at low revs and then a screaming but sweet 105db at full power. Awesome :wassup:

Wheels & Suspension

* Antera 8x17 Alloys

* Rubber, Marshall 235/40 fronts & 265/35 Rear

* Lowered Springs

(I'm not sure of the exact drop as they where second hand but drops the ride hieght by about 2" maybe 3")

I felt the standard Nissan set up was unpredictable and almost dangerous at high speed, especially over undulating road surfaces. I also found that the back end would easily breakaway from you even in the dry.

The new combined wheel, tyre and suspension mods make a massive improvement in the handling, (THIS IS A MUST FOR ALL) I'm now much more confident when high speed cornering, in the dry you can feel the back wheels bite and dig in. Fantastic adition. :headspin:

NEXT Engine Modification Ideas

(Here’s where you guy's come in) has anyone any suggestions, experience, Performance gain figures or make and model recommendations for any of the following mods. or even any additional ideas I’ve missed out.

ECU

Remap?

Chipped?

Cool Air Compartment in engine bay for Air Intake

Vents in the Hood to let cold in and warm out.

High Lift Cams

High compression pistons

Tougher valve springs

Fatter head gasket to improve compression ratio?

NOS (anyone fitted one yet) is it a ‘do-it-yourself’ job or if I try will I blow myself to little pieces

Port & Polish

Exhaust Down Pipe

Exhaust Manifold

Super Charger?

Turbo?

Traction control diff or axel from a GTS or GTT ?

Front Splitter on bottom of the front bumper

Or Bomex Body Kit

Anyway that’s all I can think of for now but I’m sure you guys out there will have something to add. :cheers:

Hey there,

glad you found your way over here - this is the place for us N/A boys :D:cheers:

re: your exhaust - if it was designed for a turbo model you might be not getting the full benefit of it - indeed you could even lose some power. I'm running a kakimoto system (main bore is 70mm, tailpipe 110mm) and I definitely notice a power drop at lower revs (compared with stock) due to lower backpressure.

The pod could cost you some power in the summer (not that it ever gets that hot in Old Blighty :() but without an intercooler reducing intake temps, I'd recommend some kind of cold air partition. Or maybe even ditch the pod and got with an uprated panel filter and a modified airbox....

I agree they would have been rubbish drivers :P

I first thought of going the hardcore N/A route with my one...I was going to put the neo head on the RB30 bottom end and go from there with lots of bolt on goodies and port and polishing....then I looked at the cost and said **** that I'll turbo the engine and keep the high compression...well worth it bang for buck!

Dan

yea i was gona do all that, but i just sold the damn car and bort a turbo. The REAL thing!

I guess its hard to part with the car u got etc.

But if not, do an engine swap :)

With the money you will spend on doing all that u could put in a turbo engine with more power ild say.

But unless u wana be all origanal and go for N/A power, do it!

well uve certainly got a nice list there. Go with what ur heart desires, ECU is definately a must, make sure u do things that give u a really good power band from down low all the way to redline. Thought about higher compression kits for higher revving ? can u imagine the power output say at 9000 rpm with forgies and shit :) endless possibilities man!

I presume forgies, are Pistons?

Thanks for that link.... Obviously these guys know what they are doing and just look at all those Skylines in the back ground on the outside pic... Luuverly

I cant suss out whats going on with the mod... almost looks like a different engine once mod is done.. but presume its a different head... obviously different manifold and ECU ..... shame I cant read Japanese... I will have to get the page translated ..if I remember correct I think Yahoo translates?

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
