Hey guys,

I've spent quite a lot of time searching through the N/A sections to try and find advice on what needs to be done to create an amazing N/A with great responsive-ness.
So far all i have managed to find is advice on how to make better power figures (OMG!!11!! BIG NUMBERS!!1!)
As a P-Plater in Vic i cannot legally drive anything that is decently powerful so the best i have to play with is an N/A that sticks within a certain power-weight ratio and as i highly value my licence i have to stick within my confines..

SO!

What needs to be done to an N/A RB20DE to make it an exceptionally responsive unit? I'm not after low numbers in a straight line, as it's daily driven i need it to be practicle and sensible but i would also like to be able to blow the doors of a turbo'd car when it comes to winding roads =]

Cheers,
Cory.

the only thing that will let you blow the doors off a turbo car when it comes to winding roads would be some sort of smoke screen or dropping tyre spikes out the back.

good tyres, decent suspension and bigger brakes will make you as fast through the corners as a turbo car with the same stuff, but as soon as they get on the gas they will be faster.

you can make it more responsive with shorter diff ratios as suggested and advancing the timing so it's pinging it's arse off, but you are still pushing shit up hill, so to speak. the rb20 isn't exactly responsive to start with compared to other engines out there. driving style will make the biggest difference. drive around keeping it above 4000rpm will help. or pull the engine out and bolt in a rb25 (although if you have a r34 25gt then you already have a rb25 in there)

or sell it and buy something lighter and more powerful. it may be fwd, but there are plenty of light hatches that will beat a NA skyline both in a straight line, and in the bends.

Is RB20DE a typo?

Cause your profile thing says you have an R34? (RB25)

Sell the skyline, buy a B-series Honda.

I had an N/A R34 for 3 years, without the power you feel the weight....bad.

If i had my time back, I would have spent the past 3 years in a Honda.

Thanks for the replies guys,

Yeah sorry Lindz, that was a typo.

I like my Nissans, mainly the Skyline and FWD's just feel wrong to me, personal preference though, not hating on them or anything.
The Skyline is probably the only thing i can currently legally drive that would satisfy my tastes, if i could drive a 350z i would have one in a heartbeat..

If i could turbo it or throw another engine into it i would but the P-Plate restrcitions would still get me.. I'm not a hoon or anything, believe me, but a little bit more power would make me smile. Too embarresed to take the NA to a track haha.

So far we have shorter diff ratios suggested, anything else at all?

Cheers,
Cory.

how much do you want to spend? you won't get a NA skyline fast for cheap. even with a small amount spent you will still get beaten by commodores and falcons in a straight line, and small buzz boxes in the corners.

as for fwd feeling wrong, it isn't until you are "hooing" that you actually notice the difference. driving to the shops and back you won't be able to tell the difference at all.

Not looking to spend heaps as it's just not justifiable, i'll get my opens in 2 years and would prefer to have a bit to splurge on something with a much more powerful base.

My girlfriend has a VW Golf, FWD, that i've driven on many an occasion and i'm not sure if it's the German design, weight or shape but it feels terrible in comparison to the RWD Skyline.

My opinion hasn't changed, Honda.

A mates lightly modded EK hatch was dead even with my 34 in a straight line.
He had a few suspension mods (coilovers/braces/sway bars) & he left me for dead in the twisties.

He then dropped a B16 in it......you get the picture.

Don't get me started on DC2R's.

Trust me mate, once you drive one you'll realise, they aren't you're "average" FWD.

what model golf? if it's just the base model then what you are complaining about has nothing to do with it being fwd. it has more to do with it not being marketed/designed as a sort of sports car. i could use the same sort of analogy as you and say that because the missus SSS is much nicer to drive than my vt wagon, rwd cars are shit compared to fwd.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!?
