hey, i have a R32 gtst type M! The mods are apexi pod filter and and 3" cat back exhaust (i dont know this for sure though when look under car it is obvious that from the cat back the exhaust is larger then cat to turbo!) I just installed a boost gauge and it is reading 10-11PSI in all gears and holds this! My car does not have a boost controller! Is this boost right as i thought it was a bit high! Do type M run a bigger turbo or more boost? Any help would be great!

Cheers,

Tyson

thanks mate, did some searching though eveyone has there own say on 32 boost.....it stock 7PSI....stock 10PSI

One more questions: I have done heaps search on 32 boost and need some advice! I am going to get the rest of my exhaust done so (dump and front and high flow cat) so it will be a full 3" system...the car will prob run about 11PSI then! Should i get a boost controller and up the boost to 12PSI - dont want to go any higher than this, and get a front mount! or buy a 33 or 34 turbo to get more boost?

Cheers

Upping it to 12 won't hurt but the standard turbo gets boring pretty quickly, so buy a cheap boost controller, and crank the psi to 12 after you've put the exhaust on, and run around on that while you save for a better turbo. Standard rb20 turbo @ 12 psi is preeety boring

Yep 12psi is pretty boaring through the rb20's.

I pushed mine to 1bar without issues for a few years before the new motor was dropped in. Old motor was 100% still fine as was the turbo when it came out.

wat mods did you have when you ran it on 1 bar? did you still have stock internals?

also on the stock boost gague in a r32 gtst type-m, the -7 and +7 on the boost gague

does that refur to psi or does +7 mean 0.7 bar or 7pi pr wat? if thry run 10psi stock, why does

the gague only go up to 7?

Edited by Josh_r32

The car just had a full exhaust, fmic and had boost wound up on the dyno. AFR's showed they were leaning out so a new fuel pump went in. It was then advanced 2 degree's and wasn't pinging on the dyno even though temps were 30degree's.

On the stock guage.. Mine was a little out, with the needle almost ready to topple over the +7 top line that was 15psi.

Have a look at the std guage it tells you the units of measurement used.

+7 is supposed to be around 13.5psi from memory. As I said mine was out a little.

thanks for all the replies! I have to agree, atm the stock rb20 turbo is boring! I will get my exhaust done and up the boost to 12 PSI Should i get an intercooelr after this? (will it give more power) or look at a 33 or 34 turbo?

im not an expert so im not 100% sur ebut i think any increase in boost should warrant a FMIC, even if it isnt totally needed it looks cool and is usefull if you want to go further later on, lots of ppl use turbos from 33's, stock or highflowed, never heard of anyone using from a 34 but dunno if u cant or what...would of thought it weas same turbo as 33, probably just more expensive...

    • 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.
