this is a good read

got a gcg hi-flow rb25 turbo going on my r32 now

other mods include 550cc injectors and powerfc and the usual kinda shit

i'll watch this thread and post results when/if i get them

our cars sound similar apart from PFC, would be good to see the differance

  • 2 weeks later...

man my engine must be buggered or sumthin...i have a high flowed turbo (not a GCG) but loooks exactly like it, and im only making 245rwhp and thats with tomei cams and 14psi and power fc....anybody know wat could be my prob?can i have a buggered head gasket? or could it be the rings?

wind it up the boost to 18psi or so.. it's probably the only way you'll get power out of it.. then it will be laggy and possibly kill an old engine. Sounds similar situation to my highflow rb25 (its running 16psi at the moment).. not the best match for rb20.

i wish i had that, ive got 253hp@22psi. RB20 hybrid, exhaust housing too small. new turbo here i come.........

sounds similar to mine..

nf: I think you'll make maybe 20% more power with raising the boost another 4psi or so... so thats quite a good result if you ask me.

may as well post up my chart as a point of comparison.

16psi on highflow rb25 turbo (rb20 actuator), k&n panel filter, 3" exhaust right thru, highflow cat, hybrid cheap front mount 450x300x75, turbotech boost valve, SAFC.. So seeing as mine is AUTO, and non-powerfc seems about in range with nF above by taking 20-30% off.

I don't think there was any temperature correction put in for the 32 degree day.. non-shootout .. So allowing 10-15%.. mine is about 150rwkw on any other dyno (probably feels about 150rwkw too).

A fair bit of blowby at 16psi exhibited in my engine, whereas was none at 12psi... so any more isn't a good idea in mine at the moment.

sorry don't have a scanner or camera here so i'll try describe

also graph doesn't have RPMs so someone might have to convert

in 3rd gear, peak power at 114km/h, made full boost by 82km

graph is a nice curve too :(

mods that are important:

- split dump

- splitfires

- iridium plugs

- k&n pod

- 3 inch full exhaust with a hi-flow cat (crowbar brand)

- the turbo is r33 gcg hiflow with i think the r32 actuator

- 550x100x76 intercooler

    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
    • You haven't driven many modern cars then have you? Most of them have sfa steering feel with their stupid electric bullshit steering systems.
