hey all i just had my r32 dynoed at hyperdrive, when i bought it i was told it had about 299rwhp with a miss, i wasnt sure so i took it to hyperdrive this mourning with spitfire coils and only pulled 265.9rwhp at 14psi, the boost was all over the place, the guy at hyperdrive told me the hks 2540 wont really do anybetter than that :D so anyway im gonna get a new turbo, any suggestions where to take it or what turbo to get??

cheers

i recommend the HKS GT-RS i think brand new from www.greenline.jp is 2.5k give or take...i've been in [Michael]s car and damn its responsive and powerful hahah or even the Trust TD06-25g or 20g but i would go the HKS because its coolant and oil cooled the Trust turbos are only oil cooled also the Garret GT30 series they good to hehe :D

Nothing wrong with the 2540. As people have said it will net upto 350 or so and will run 18psi.

Your setup will make a very easy 350rwhp if it really is a 2540.

Topracing is open this coming Monday but as we closed for 3 weeks the backlog is quite big so best ring John about booking anything.Its the time of the year we build new racecars and refresh/upgrade the current ones so it may be tough to get in for anything other than small jobs.

Damn you're only making 20hp more than me and all I've got is a stock 25 turbo! same dyno too.

I've got a GT35R with a .82 rear housing waiting to go on my engine.. I reckon it should chirp 2nd :blink: would suggest either a GT35R with the smaller .63 housing or a GT30 for your engine. Pick a hp goal and have a read through the 25 turbo upgrade in the FI area.

    • The alloy coolant reservoir has a sight glass, so as long as I can see coolant in the sight glass it's GTG, as for PS, it isn't anything catastrophic if it gets low, and as it hasn't lost a drop since I have owned the car I cannot see it being an issue, even after putting the "big block" 2.5 in....LOL The only time it gets slightly messy is at oil changes, as the oil filter sits above the frame, and I need to use a plastic bottle with its bottom cut off to catch the flow when loosening the filter
    • Good on you for taking on the job, but it is a big one. Even if you have bolt on manifold and turbo, you will need: Post throttle pressure source to boost controller to wastegate (and FPR, and ECU/MAP sensor) Pre throttle pressure source to top of BOV(s) Oil feed - you can take that from the standard port in the middle of the block Oil return to block under the turbo - this is much trickier than it seems to route a decent/wide pipe past the manifold. You really can't use rubber hose because it is way too hot there, and also the oil out of the turbo core is a bit frothy so it needs to have a decent diameter Water feed - you can take that from the standard port in the rear of the block. Water return - mine runs to a T into the heater box return, just make sure you don't create a high point making bleeding hard. All of those lines should use 200 series style teflon braided hose with heat shielding because everything needs to be routed past the manifold. Also a turbo beanie is a really good idea to minimise the chance of the car catching fire (under bonnet lining in particular) You also need to decide a cam cover breathing solution as well, will you vent externally via a catch can (probably illegal) or return to the intake (plumbing required and can oil up everything over time) Keep in mind the intake and exhaust piping in the engine bay will be custom so you either need to be able to fab ally and steel or have someone you can get a car that isn't running to. Get the wideband fitting welded into the dump pipe at the same time. Also, just my opinion, a screamer pipe attracts attention and doesn't add power, I'd plumb it back if you want to be allowed to keep the car on the road. BTW do you know anything about how healthy the motor is, and what power you are targeting? Doubling or tripling the factory power on an unknown motor is a little risky. Also fuel system will need some attention (pumps, high current hanger, direct power and earth feed, injectors etc)
    • Wrinkle black will be a thing for both
    • As I wait for parts to be delivered, I have managed to procure via a contact a R32 Nistune ECU......for now I just want to monitor what the car is doing but eventually.......who knows where we go 😂
    • To back this up, I'm always looking on the outside, seeing the level, and then opening it up anyway, as I'm worried the level I've looked at, is more so a scunge line. Then you end up dipping your damn finger in it too depending on the type of tank you're looking at just to make sure I'm not going insane.   PS, Mark, polish up the none moroso one a bit and then give it a clear coat. The Moroso one looks to be way shiner (not mirror polished, just shinier) and it'll still look weird with the two different alloys beside each other. Either that, or Id probably paint them a flat black...
