Engine Work

[BNR]

Hey

Ive currently got a 1989 R32 GTR thats coming up to about 90,000km. It is totally stock running standard boost with standard airbox still on. The only mod is a Trust 3.5 inch cat back exhaust with a canon.

Im looking to do some engine work without spending a crazy amount of money. In the end i would like 280rwkw - 300rwkw, around that.

The car wont be driven that much and on low boost most the time so i think the gearbox and internals should hold up.

What kind of mods would i need to get to achieve this power ?

Should i gradually work the car up or buy all the mods and stick them on at once ?

How much should i budget for parts and labour ?

What would be the best turbos to choose, ive been told HKS GT25/30's are good ?

Thanks, Mark

For 280 rwkw, get some steel turbines in the standard turbos and turn the boost up to 1.3 bar. Cost ~$1000

Power FC with Boost Control Kit and tune ~$1600

Split dumps, decent engine pipes and high flow cat ~$1200

Pipercross filter in the standard airbox ~$50

Bosch 044 fuel pump mounted in tank ~$400

The standard injectors should just about make it, if not use a Nismo adjustable fuel pressure regulator ~$150.

The standard drive train will be fine at that power level, however you will need a clutch upgrade ~$600

Labour is difficult to quote on, depends on how much you do yourself and how expensive your chosen workshop is. Maybe allow ~$2,000 that should cover it.

if you settle for upto 270rwkw

you wont need an ECU, any turbo mods/aftermarket items.

Large saving right there.

Only a clutch

set of cam gears

better cat

fuel pump

panel filter in the stocker airbox (which is best)

pretty cheap indeed.

My friend made 280rwkw on a standard GTR by adding Power FC, adjustable cam gears and N1 turbo's. Everything else was stock......He even has the standard air box. :uh-huh:

for N1 turbos you've be wanting over 300rwkw... i wouldnt be happy with that

Ben at Racepace told him that he will need an in tank pump to get into the 300kw mark.

Forgot to mention ive already got a button clutch.

I would like to keep it down to about $5000 so im looking at the best package.

What do u think i would get out of this ?

-Stock R32 turbos 1.0 bar

-Dump pipe with high flow cat

-Apexi Power FC

-Fuel Pump

-Cam gear

Is the car going to be reliable running 1.0 bar thru the stock turbos ?

Another question say i did the above and got around 270-280rwkw, if i decided to get some bigger turbos later on would they just bolt on to give the extra power once i retuned the ECU ?

I wouldn't recommend doing any upgrades with the stock turbos. they are for stock and only stock. Although 1 bar they say is the limit for stockies, heard of too many people wasting motors with stock turbos, new and old due to not knowing bad history of car, over boosting for those special moments, etc. For peace of mind, i would look at steel turbos first of all. save yourself a $5k rebuild. I was lucky. didn't blow my motor from ceramic crap being bounced back in when the front turbo let go. got mine wound back to stock boost till i can afford what i want.

for an extra $300 ... fark it'd be the first thing i'd be doing

Whats it worth per turbo to drop on a steel turbine wheel?

[R31Nismoid]

Whats it worth per turbo to drop on a steel turbine wheel?

$300-$400 at a rough stab with all the balancing etc.

possibly slightly around $600 per?

Dude,

it's actually closer to $1000-1100 per turbo as the exhaust wheel needs to be replaced, and in the process the turbo gets a full reco kit put through it inc. a 360 degree thrust bearing to allow the turbo to withstand longer periods at higher boost levels.
