Been toying with building a time attack dedicated car for a while now and been looking at a few options and running them through my head.

Seaming that lightweight awd 700hp cars like the cyber evo seem to cut the quickest times at eastern creek and also in japan and the US I'd like to keep those basics without building an evo or wrx and build something different.

My first thought was a R32 gtr as I need a heap of interior parts to finish off my street gtr so that would work well.

I was thinking of doing something different and selling the 26 and building a vh45 twin turbo and make the awd work bit of work but there is just enough room to mount a diff to the subframe and keep the diff and engine separate.

My theory there with the v8 not needing big turbo's to get a nice 600-800hp range and have some nice low end drive out of corners torque.

On the other hand on a big jenny Craig diet with carbon everything they curb at 1250-1350kg.

So was thinking other lighter cars to start off with Silvia came to mind with the same v8 setup but no awd.

Then I started to look at a GTIR and did a little reading and found they have a pretty poor weight distribution of around 65/35 and coments on understeer I'm sort of leaning away from that.

I was even considering ditching the sr20 for a vq30det with a vq40 crank to bring it up to a 3.8 being that a vq isn't that much different in weight to a sr20 but will add a little more to the front.

GTIR came to mind as they start at 1220kg so sub 1100kg should be achievable.

In keeping I'd like to keep it in the Nissan family but did think about TX3 laser and a few other smaller awd cars around the 1100-1200kg mark.

Any thoughts would be greatly appreciated as I wouldn't just want to follow the crowd and build evo as I thought a v8 powered turbo gtr would be something different just think it might be a tad heavy seeing the GTR times at the last time attack.

Cheers David

Buy an American GT car as a roller, something like the RX8's that run in the series over there. Slot in either a 20B turbo, or a late alloy chev (I'd chose the 7 litre, add no turbos) depending on your personal slant, and enjoy :)

Hollinger S6 'box would be the go, and it'd be pretty cheap to campaign, with good suspension architecture.

Cheers mate never thought about us gt cars did think about a v8 supertaxi roller then read the rules and no space frame chassis.

No a chev fan even tho make good power not a fan of chev and to be honest I don't know how they have gotten away with a 2 valve push rod v8 for so long.

And the chicken cookers make good power sound insanse but don't last long enough.

Yeah for those reasons it's a great engine but for a street engine to pass emissions and now with them in the shit it doesn't look like they will be building an over head cam engine.

Your right weight is the key that's why I'm torn even tho I would like to build a gtr and like them a lot the extra weight is putting more off.

Even tho I do like evo's and would love one it's not different and just following what is already out in front.

+1 to this.

The Grand Am RX8's are a weapon and come already fitted with a VERY angry NA 20B (think faster in a straight line than 500hp BMW M6s that run in the series too)

Roy the fact that it's a chev and it's becoming the norm just stick an ls engine in it.

True with the more cost but with a set if hair dryers you would get away with a nice re grind of the cams to get up to 700hp.

I can think of 3 or 4 cases of people wanting to drop a VH/VK v8 in a GTR, one mob even started doing it.

None were ever finished, even with a huge budget.

the VH/VK V8s are a very big engine for only 4L, so much so that they would be heavier than a RB.

If you want to be Different than look at getting a rebuilt FR9 or R5P7 Nascar V8, 850+hp on E85, and will last until the end of time in a hot lap car.

Also they are going to Fuel Injection next year, so the likes of Roush/Yates will be doing all the R&D For you

That is very true on the vh it's a big engine but a very good engine at that. Just love the idea of a turbo v8 gtr very different.

I did see NASCAR are going efi and in testing which would be interesting.

But again weight is an issue with a NASCAR engine and a gtr when an evo doesn't need much to get it to 1100.

I will be competing next year with our r31 to see how we go so this build needs a bit of planing and thought to which car to pick and which engine to choose.

The other thing in the back of my mind with swapping the engine out is for other classes like improved production etc an engine swap other than a bigger four or bigger 6 won't let the car run in that category so rules it out of a few classes

Need a budget and an expectation.

I you want to run at the front your going to need 150k for a chassis if you can't build it yourself (bolt on parts are just not going to cut it) and do you have the talent to drive such a car at 10/10ths....

If you don't have a massive budget forget the Nissan idea all together and build something like the kallis evo.

Minimal outlay (relative to others) easyish to steer and potentially very quick.

You won't get the shits with it trying to chase geometry issues and end up spending 80k to get the chassis competitive.

What makes you think a taxi is a space frame chassis.

It's a supercar chassis not a space frame.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me
