hi guys,

Im currently looking at a few possible turbo options for my car. Im aim for 450-500Hp at the engine with this turbo. Now i first was hoping to stay with an internal gated turbo to keep the engine looking at stock as possible, but after doing some research, it seems that a turbo which has external gate will hold boost better, and have lower spoolup times.

Now is this true. Im paranoid about being defected, so basically if i can have a internal wastegated turbo that will hold boost well, then id be happy to do that, but if my setup wont work efficiently with internal gate, i spose ill have to go ext.

Im looking at garrett turbos atm. Is it possible to somehow fit the stock heat shield over a new low mount turbo setup? Im sure i could modiy it somehow to make it look stock.

Thanks

Dean

The HKS low mount manifold going on mine has provisions for a heat shield. But saying that it still wont stop a nice police man for defecting you for that non std. gear knob. U know, the big safety issue it is :D

With mine....well if you are gunna get pulled over for a bs reason...go the whole hog.

But yes bigger turbos were meant for external wastegates....if you wanna do it properly go the external. Im not saying people dont have good results though from an internal wastegate. The new Ford xr6 is a GT35 internal gate i believe...ford must have some trust in them :)

Regency (Transport SA) has final say. Engineers reports, ADR tests anything means nothing to them here. If they are unhappy with it, it wont pass.

They even defect ADR approved steering wheels, Engineers certificates, and emission tests (which here in Adelaide cost 2k+)

And you cannot take them to court, because they are covered by the law itself...

that's a hard one, 500hp+low mount+ stock looking? i think maybe you should raise your middle finger to the law! a 500hp motor is easier with a big single on a high manifold, but the first option i can think of is the HKS 3037 with internal gate, which may be hard to find.

if you are going to change the manifold go external gate, if keeping std manifols go internal. My reason being that the external gate position on the std manifold as per may last setup is not the best and its not easy to set up right. But if you are chnaging the manifold go external and mount it low down below the turbo.

Grepin runs a 2835r i think and is making 280 or so and its internal gate, JMS have on on their site for 2500 is a t25 flange but can use adaper to make it fit, this would be ideal. You will make a easy 250rwkw and shoudl do 300 just with a internal gate turbo.

I got a GCG 450hp turbo and it makes around 265kw at wheels.. Not sure on Hp, I think its about 360 or so.. Looks standard but hauls arse over the standard turbo.. But then again its around 2k for the rebuild so you have to weigh up what you want the car to be for before selecting your turbo setup ect..

$2000 to rebuild ur stock turbo or $2400 for a nice new twin ball bearing garrett GT30.

I know what i would be buying and did buy.

If u r serious go external gate, you know you will get bored eventually and get one in the end :)

Sounds cheap being a $400 difference, but show us the real costs in the transplant!

robo youd have to beat my car in arolling run because you have 3rwkws more and 600rpm less lag! ive just had my stainless manifold fitted and will be getting the car tuned shortley will post my results. i doubt ill get much ove 225rwkws??? if i had my $2000 to spend again id go a gt30 everytime . yes more stuffing around to fit but you stand to gain more power in the long run.

    • 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.
