hey guys, i was looking at getting a GT3071R with a 0.64 rear housing on a T25/T28 flange. was wondering if this would push to much boost for my stock internals. i currently only have 255L fuel pump , 3" turbo back exhaust, FMIC. i would obviously be getting a ECU remap straight after and have already got a boost EBC. ANY HELP PLEASE ? my goal at the moment is 200rwkw+ but am looking to go further in the future and what a turbo to support this statement!

Theres heaps on here about how much the stock internals take, but I think anything much more over that your usually relying on the motors past history and chance etc.

I think the turbos a good choice, im actually looking at getting one myself - good tradeoff between response and power it seems

No the biggest factor is it won't bolt to your exhaust manifold , T25/28 flanged exhaust housings are too small at the inlet for 6 leg exhaust manifolds . You really need someting with a T3 flanged exhaust housing .

A .

Surprised it took that long for someone to point that out...even the dump pipe won't fit...and if you are chasing only 200rwkw or so then you are looking at the wrong turbo...

same turbo with different exhaust housing is 280rwkw capable though.

for 200 ideally get yourself a hks 2510 or 2530, pricey and getting old though if second hand. The problem you have is that all of the small frame garrett turbos are t2 flanged, the smallest t3 flanged one is the 3071.

You could get your stock turbo highflowed, but even they are generally optimised for power around the 250rwkw mark so you have the response trade off.

Or you could talk to a turbo shop about getting a t28 cored turbo fitted to a modified stock exhaust housing. I would suggest a gt2860rs if you are going to be happy with low 200's, 2871 if you want a bit more.

    • 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.
