my mate had the masterpower t70 with a top mount manifold and a 45 mm PSR wastegate with forged pistons etc, and made 330rwkw on 1.8 Bar. He had a standard head so now that's being worked and we are changing turbo again, it can pull good power and we hit full boost and about 4800rpm and it kicked really hard, but it still felt too laggy for a daily driven car. but when it came on boost it was crazy.

did you do a search or some investigation before buying a new turbo? the turbo is generally one of the last things to be replaced. be careful not to rush into it (cos its cheap) as you may end up with a lag monster car or something could go bang (no longer cheap). you should look at upgrading the following items before you fit the turbocharger to your car

injectors (stockers run out of capcity around 200-230rwkw, 550cc minimum)

airflow meter (stocker runs out of capacity around 220rwkw, z32 or q45 afm)

tyres (stock or crappy tyres will just result in lots of wheelspin)

suspension (standard suspenion will hamper your launch capabilities)

brakes (stock calipers should be ok, but you should look at some good rotors and / or braided brake lines and good pads)

ecu (stock ecu will be useless. go for aftermarket stand alone. recommend apexi powerfc)

fuel pump (stock pump will run out of capacity around 200rwkw)

intercooler (stock intercooler will run out of capacity around 180rwkw)

exhaust (stock exhaust will be useless, at least 3.5" dump pipe / front pipe and 3.5" exhaust with hiflow cat)

boost controller (good a good bleed valve or electronic controller)

pineapple kit (to prevent axle tramp)

standard plenum is fine (no need to change)

i'd say its going to cost you around $8k to have this turbocharger fitted and working correctly

yeah good call croat, any prices / quotes you are given double them as stuff will break, wont fit, wont work etc etc. i thought 8k was fairly ball park. that wasnt assuming stock rb25. i was assuming it had tyres, suspension and some of the basic mods already but your right, its always more, never less

    • 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.
