r32 question

[nemz]

hey ill just give a short descrip of my car, and want some suggestions of what to do.

alright first off. its a 93 model r32 gts-t, 75,000 on the clock, v.good condition, running a k&n panel filter, hks superdragger exhaust 3" all the way with a larger tip about 5"?, 6 finger brass button clutch, quik shift kit, turbo timer, no boost guages or anything, now im gonna be doing stuff bit by bit, just wanna know where i should start, any suggestions?

[TTT]

Next I would say buy a boost guage and then some sort of boost controller to safely turn the boost up a little bit.

---On the cheap---

$100 for autometer boost gauge

$60 for a GFB bleed valve

---money is no problem---

$200-$300 for some jap brand boost gauge.

$400-$1000 for an electronic boost controller of some sort.

It is comming towards summer so I wouldn't be putting the boost up too much on the standard r32 intercooler.

next logical step would be intercooler.

---on the cheap---

$200-$400 for an R34 GTT intercooler (direct swap but it is almost twice as thick as the stocky. is flowing and cooling enough for 206kw in standrd form on the R34 GTT

or

$600-$900 GTR intercooler (plus piping to suit - maybe another $500)

---money is no problem---

$1500-$2500 for a NEW good Jap intercooler kit (with everything required to fit it..)

at this point you could go turbo or fueling.. probably safe to do both close to one another..

turbo

---on the cheap---

$400-$600 for an RB25 turbo (remember to use the RB20 turbo wastegate acutator so it will run 10psi in stock form compared to the 7psi you will get from the rb25 wategate)

---money is no problem---

$???? for some high spec JAP brand capable of some magical dyno figures..

Fuel pump and computer

---on the cheap---

$100-$250 for a GTR fuel pump (it flows 195L/hour compared to R32 GTST pump which is 135L/hour)

$200-$300 for a Standard ecu rechip for better fuel maps (also removes speed limit and can raise rev and boost limits)

---money is no problem---

$300-$900 for a Bosch or SARD fuel pump

$1000+ for some after market complete ECU.

I think that after this point, you would be looking at some serious money for cams and head work and so on.

I've only listed engine mods here, there is also a whole world of suspension goodies to spend your hard earned dollars on..

WHITELINE is a good AUSSIE place to get stuff for your car.

ROY from these forums has the whole package from them (and when you find the page on their website for the R32 GTST's, the pictured car is his I believe..)

Other than them, JAPAN is the place to go for tested packages for these cars..

Don't forget to save some money for the 100,000km service too..

does that Essay above help?

[BHDave]

Damn, can't beat that essay. It's pretty comprehensive.

Get a boost gauge (100 or so), then i'd be going front mount intercooler (you can do it for less than a grand if you know someone who welds) followed closely by a pnumatic boost controller( less than 150). You can hold a bit more boost safely that way and a bleedvalve is cheap too.

The stock actuator will have have boost dropping back to about 10psi at 6500rpm no matter how high you screw up the boost, so then you can get an adjustable actuator (HKS is 270).....and the list goes on.

Don't forget suspension and brakes or you'll have a real fast boat that'll want to understeer into walls and guard rails and gutters and stuff

thanks for the help man

[nemz]

whats the 100,000km service?

oh btw i was planning on getting an intercooler next, and spending about 1100 on it

[TTT]

100,000km service is probably the major service that you will get for your car.

Main things to change for safety are...

water pump

timing belt

radiator hoses (if they are brittle)

diff oil

gearbox oil

brake fluid

clutch fluid

power steering fluid

spark plugs (if they haven't been done for over 20,000kms)

BELTS (make sure the mechanic checks these properly)

radiator coolant

you know.. all the things that are important but hardly ever get changed...

oh.. clean your Air Flow Meter too.

and your air filter if it is an aftermarket one.

[nemz]

hey where can i get it done at? and how much we talkin?

p.s if i wanted to get a bigger turbo, what would be a good second hand one that i could pick up for about <$1000

[TTT]

any mechanic can do those sort of things above.

Bigger turbo for $1000... I don't know.

I just got an RB25 turbo and put that on mine and I'm happy enough with it.

If you were to pay about $2000, then you could either get yours rebuilt or get a new ball bearing GT28 of some sort which should support about 350hp.

If you don't have a regular mechanic, then all I can recommend is my one.

He has already done my 100,000km service.

But I changed alot more than what I listed above.. and it cost me just under $2000.

(I had to change the radiator and all the bushes..these were the main costs.)

[Cubes]

I did the cam belt and waterpump at the same time myself.

The waterpump cost me with gasket $80 and the genuine cam belt with markings on the belt to make lining up the cam and crank easy was $90. It took roughly 1 day.

If you do decide to go it by your self let me know and i'll rip the few pages out of the R32 Engine manual I have which gives a step by step guide and what tools you will need. i.e harmonic balancer puller ~$20.

What ever you do don't put a bigger fuel pump in the car until either yours is dead or you require the extra fuel due to bigger turbo's etc.

I was making 152rwkw on 12.5psi & stock IC with a slight fiddle of fuel pressure using a cheap bleed setup on the fuel pressure regulator. Mid range and top end AF's were pretty nice.

As soon as I fitted a bigger fuel pump to allow the top end AF's to be nice the mid range would be leaning out heaps.

So Don't put a bigger pump on it unless you have to, you will loose power.

hey gtst

i noticed on a thread that you had someone to recommend as a mechanic in the sydney area. as i also need to undertake close to $2000 in mods & repairs very soon i was wondering who you mechanic is.

also the R34GTT intercooler is not a direct fit (as i found out) as its pipework is the same as a R33, ie one of the pipes points the wrong way

ta for any info

pm'd you cul202
