NA build ?

Recommended Posts

I'm possibly wanting to try and extracted a few more horses from my zed . I would love to supercharge it but at £11k + it's a lot of dosh , yes I know you get like 450-500bhp but still it's a lot of money . What can be done with say 5k ? Cams? Head work , pistons , And what sort of gains could I expect? Is getting 370 at the fly achievable ? This is on a HR zed .

I've spent about 5k just getting my nitrous installed and running.... 5K won't get you far unless you can do the work yourself, and from others experience, you really need to be a real pro engine builder to get it right and not go boom

I've not seen it done (not that ive looked for it) but 370 fly would be tough for 3.5litres NA on paper for a road car. its over the 100bhp/litre mark.

 

I refer to my signature... so dont listen to anything i say.

that being said... get digging for someone who has.

 

Theres a chap here with 340@fly with wild cams

 

The standard specs for the HR cams are:

Lift:

Intake/Exhaust : 10.5mm/10.5mm

 

Duration:

Intake/Exhaust: 248/248

 

Intake Open: 2º BTDC

Intake Close: 66º ABDC

 

Exhaust Open: 68º BBDC

Exhaust Close: 0º BTDC

 

Overlap: 2º

 

which you knew that im sure.

With your 7,500 rpm rev limit they appear like a very mild grind to me! in fact my DE specs arnt far off. Does the HR have variable timing? (i dont know this answer, but im assuming it must do).

that being said, the high rpm limit gives you scope for bigger cams.

The first hit i found was GT Motosports on stateside, offering a warm 264/258 duration spec.

or Jim Wolf does a couple of specs.

Cams will be £800+springs etc before labour fitment. Alot, but leaves you a sizable budget left.

 

 

Actually.... no i'll let you do your own research. lol.

here:

HR, NA 310whp (so not far off your mark)

HR, NA 323whp (this is a solid 360bhp no matter what tranny loss you calculate with)

HR, NA, 400whp ! (bored out/stroked to 3.7Litres though)

What is in / out of budget is for you to find out. :-)

 

 

I'm sticking with my DE :p

I have the money , it's just I'm not sure i can justify spending what will probably end up being close to 13k 13k + my 350 ( 9-10k ) 22k... You can get a lot of performance for that money

 

ive had the same thoughts and i think ekona is right a group of us are going for some proper training days ;)

no good having all the gear no idea!

i am talking about myself there lol

Driving lessons. As in, proper performance driving. You'll go much, much quicker with £5K tuition than with £10K of engine mods.

 

Ya it's a good shout but to be honest I'm not talking about track driving ( think you are? ) I want something that when you put your foot down out of a corner it makes you hold the steering wheel tight !!

Scrap this idea then :)

 

What to spend 5k on then !

travel

 

I've been very lucky and spent many months traveling with my wife over the years ......

 

Off to Mauritius for 2 weeks in jan :)

 

fair play

i know what your getting at with wanting that spine tingling power

what made me think was my pals looking at rs4s etc that have had work done and are around 6/700 bhp for 25/30 grand lot of car for the money

That's me that is All the gear and no idea :lol:

 

Even going to build a tire rack and carry a spare set of slicks - my theory is if I look like a pro no one will have a go at me on track and if/when they go flying past I'll just cough and say shake down run and err need to bed in the new 5000hp engine (clear throat) cough - and suddenly spot something that needs my urgent attention somewhere else :thumbs:;)

What about putting in a cheeky bid for this item: http://www.ebay.co.uk/itm/NISSAN-350Z-APS-TWIN-TURBO-FOR-PARTS-ONLY-BREAKING-/221594953663?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item339816a7bf - It's been sitting there slowly deteriorating away for a while now wont be worth anything soon as it's obviously not moved for a while. Yeah yeah big build worth a ££££ - but no, it's worth what someone is willing to pay for it and they must realise that by now and it's not appreciating rotting away there!! :teeth:

I'm sure that engine with TT was up for £5k a while ago - if it is what they say then make a great start for someone - assuming it is all still serviceable the front IC is damaged to start with so would need a good going over.

Exactly :) £3K, - £2K to swap it over, repair or replace parts where needed (they still sell the kit in Oz) and a retune/any extra fettling needed + £1.5K more back for the original engine, Fanny's your auntie :lol:

ive asked about that TT a few times (I only wanted the FRS :lol: ) but kept saying someone is interested in the whole lot and would let me know if they dont take it. God knows how long since i re messaged them the other day and got the same story, They obviously want to keep it whole so I reckon a cheeky offer on the lot will see you good :thumbs:

...oh and lo behold!

 

Never buying a bean from A1 Jap again. had grief with them over Celica parts before.

 

But, that aside, what is sitting there must be worth something to someone.
