$9,000 Budget On Engine Internals, Whats Achievable ?

[phoenixgoldskyline]

Hey Guys

Just wondering what the going rate is these days to get a r33 gts-t engine built to handle 400rwkw, i want it to be a strong engine, not an engine i will just boost up for the 1/4 mile. As i am in melbourne which turbo mechanics would be best to go too?. I want to spend about $9,000 tops on the engine internals to achive 400rwkw, do you guys think this is posible on this budget?

What type of modifications can i aspect for $9,000?. The turbo is not included in the $9,000 as that will be purchased in the near future.

Cheers Guys for your help

I suggest you look at an RB30/25 hybrid.

I've heard good things about Race Pace in Bayswater

[RNS11Z]

Let us know how far you get with $9k. I've learnt that yes you may spend 9k on the engine but your going to spend about the same or less on suspension, diff, computer and so on. I would get expert advise before i went ahead and built a 400rwkw bottom end. Pm Sydneykid as he knows alot about this sort of work.

Good luck

Yes. The only two people I would recommend, would be Race Pace motorsport in Bayswater

or ICE Performance in Cheltenham

Hi Shaun, I really need to know a few things before I can comment;

What have you already done to the car?

What is your horsepower target?

What are you going to use the car for?

What work can you do yourself?

What is your budget?

Be realisitic in your answers and I will try and give you reasonable suggestions to suite.

Hey thanks guys for the replys,

Hi Sydneykid, ok so far i have a stock as a rock R33 Gts-t, things like exhaust sysytem are no dramas as my mate works at an exhaust shop. Horsepower target hopefully will be around 600Hp, (447rwkw i think). The Budget i intend to spen on "JUST" the engine alone is $8,000 - $9,000, i have a totally different budget for other engine parts. So The Engine has to be built to handle 600Hp for $9,000 is this possible?. The intend use for this car will be a bit of every thing 1/4 mile, daily driver and drift car:D. I will be able to do some things myself but other thAn that i can get it done threw my mates or if worst comes to worst, threw a turbo workshop. So Rember ($9,000) to Spend on engine internals, cams, rods, pistons ect ect all the stuff to make a stable and slightly worked rb25det engine.

Thanks for the help guys

Shaun

PS: I want to build me car around the JMS R33, but without stock internals:p. Turbo i will be using is a Garrett GT 3540.

Firstly you said bottom end, then referred to cams etc, so i take it you mean engine internals.

A budget of $9000 will probably get you the pistons, rods, cams, valvegear, but my concern would be that at those sorts of power figures, what is a realistic km expactancy for an engine with so much hp/Litre. 160kw/L at the wheels is a lot of power.

If driven as you would expect such an engine to be driven, is it reasonable to presume every 10,000-15,000kms that the engine should stripped and inspected... afterall it is a hell of a $$$$ investment.

[B-Man]

YEah - I don't think you will get 447rwkw out of the Rb25 without doing somehting radical like stroking it and putting a huge turbo on...

But if you do - I wanna see that !

Good luck dude !

[Morgs]

I honestly couldn't see 9K achieving your power objectives.

[RbHed]

this i have 2 c... turning a stock gtst into a 400+rwkw from scratch

good luck wit d project

get a JUN or HKS motor?

[Sydneykid]

Hi Shaun, we have a 3.1 litre engine on the engine stand, it has;

JE forged Pistons

Total Seal gapless rings

Carillo forged conrods

ARP rod bolts, head and main studs

Balanced and linished crank

9 to 1 compression ratio

O'ringed block

HKS exhaust manifold

Garrett GT3040

Clevite bearings

N1 GTR oil pump

N1 GTR water pump

Winged and baffled sump

RB26 head, throttle bodies and plenum

Head is ported and both manifolds are matched

(it flows 645 bhp on the flow bench at 2 bar vacuum)

Iskendarian valve springs

Titanium retainers

Tomei head gasket

Jun adjustable cam pulleys

Standard R32 GTR camshafts

I haven't run this one on the engine dyno yet, but it's sister (there are 5 in this batch) made 625 bhp at 7,250 rpm using Elf LMS. With upgraded camshafts and a GT35R, 700 bhp would be easily achievable. As for durability, the sister engine has completed a full season of racing (circuit and drags) and 6,000 k's of road work. It's leak down test is within 3% of when it was new, so another season is on the cards.

Does this sound like something you would be interested in duplicating? Depending on how much work you can do yourself and how many of the above parts are outside you requirements $9K should be doable.

Tick off the bits you need and I can tell you how much they will cost.

newbie curiousity...

how much of that list could a normal person do themselves??

i mean with average garage tools and a workshop manual or something???

[lukevl]

Don't take offence, but almost none. All the parts have to be 'set up' if oyu know what I mean. Not just installed. Well, bolting on water and oil pumps is okay. Engine rebuild? No.

[Sydneykid]

Hi guys, assembling the bottom end of an engine, bolting on the head and setting up tjhe camshafts is best left to someone who has the experience and the equipement. But that is less than 50% of the time it takes to assemble a complete engine. With a limited number of tools and experience many people can do the other 50%. Stuff like bolt on the oil pump, sump, water pump, cam tensioner and idler, flywheel. engine mounts, air con compressor, oil filter, turbo oil and water fittings, power steering pump, cambelt covers, coils, etc etc.

Saves money if you have the experience and tools.

well, thanks for the info neway.... much appreciated
