As most of you might know i am doing an upgrade on alot of the components of my car. The only thing i am undecided on is the turbo.

Does any1 know if all the internally gated HKS turbos have the same dump pipe flange eg 2530, 2835 pros s, 3037 pro s or are they all different?

What about the Garret ones are they similiar or all different?

Cheers

Dynamic turbo chargers

Speak to a guy called Steve on (02) 9757 2766

Tell him that Robert from Bar None Motors up in Forster said you would look after him regarding price and service

The flange is T3 which is standard RB25 size

...and let me tell you it looks really horny.

i dont think i will be driving all the way to sydney just to get a turbo supplied!

It may be T3 flange but if the housing is 2 big it wont fit properly in thestock location with using a spacer plate!

take some pics of it and what price is he charging u for supply and installation?

Hi INASNT

Since I do a lot of work with them my price will be different than yours.

However there is a solution. How about you looking around and getting your very best price and then i'll ask him to beat it! Just be honest, as I know how much they are selling for.

This 1.06 AR rear GT40 is will fit the std manifold with a spacer as the compressor cover is only 1/4 inch bigger in diameter than the TO4 that came off the car. Spacer will be approx 12mm.

Specs are:

4" intake

2.5" output

3" exhaust + the wastegate opening (around 2.5")

The spool up will not be as good as the .82AR rear however I wanted the 700 turbo to big me a big hit from 4,500 on up and not run out of puff through the to high rpms.

Pics of turbo off and on car will come soon.

INASNT: Re lag city.

Just the way I like my turbo charged cars to run. With my mods, it should be biulding 14psi boost by 4500.

I'll let you know more soon but for now the plans to have it ready has blown out to Thursday next week.

The fuel pump was ordered incorrectly and getting another up with take till Wed. BUGGER!

yeah you are right. I couldn't believe it. Just had to try it out. The wastegate is quite big so it will be fine I believe. Also, we are going to run a screamer pipe so should sounds a hoot.

Oh and BTW, it is much cheaper as you can understand as you don't need any change of manifold or spacer for the external W/G. The wastegate alone is no cheaper than $600 say for a good sized W/G.

That all adds up to a super deal for the lastest "big" Garrett turbo don't you think?

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻

      Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”

      Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
