3037 S uses standard exhaust manifold with custom HKS dump as will the 2835.

Will I loose much more bottom end with a GT-rs? as compared to 2835/3037

I would also like to know how much torque these various turbo's will produce (i have planned to install 260 degree poncams aswell)

Anyone know?

if your interested in dragging, why would you even consider a gtrs?

im not a fan of them at all.

way to much money for way to little return.

my opinion only

on a stock bottom end 3037

on a built bottom end gt3582

im running the latter with poncams and i can see 5 psi at 2500rpm

but i can also sit on 100 kph in second gear being auto, floor it and instantly the tyres light up at 100 kph,

it changes into drive and the speedo goes of the clock. in around 2 seconds. (keeps the crowd happy)

a gtrs struggles to spin the wheels at all.

great turbo to have purchased.

I have one on my JZX81 1JZ-GTE. awsome torque and great power throughout the rev range.

Mine makes around 290+rwkw on 16psi.

Then again my engine has a few more toys inside and out.

Will be keeping an eye on your posts to see what you get out of it with Martins skills behind it.

Goodluck

Sry to side track your thread man but would like to know a bit more about 32 4whore's set up as im going for similar power figures. Like are you running standard internals?

Got a retune yesterday by a well known member off this forum with a wideband and Datalogit now running 18psi and made 273.9rwkw on Aussies Dyno Hindmarsh today (previously 258 on their dyno). Cheers mate

Adrian, is that a suggestion to Lee to switch over to E85, or are you asking was the 273.9rwkw figure from switching to E85? My guess is the new power figure is still on 98RON petrol.

Lee, nice result. I bet the torque increase feels good too. Add another couple of psi, some mild (256-264 region) cams and you'll go close to 300.

Speaking of E85; I've got a new fuel rail (14mm o'ring - chromed and gleaming) a brand spankers set of 910cc Siemens and have just wired up some new connectors to suit. Now I just have to wait until the 06 Jan to tune it all. I don't think I'll need to upgrade injectors ever again. I started out with 780cc in mind, then decided to go for 870cc... then the 910's popped up.

Hi Matt

was just a suggestion,

are you going to do back to back testing still? If you dont mind me asking what did the custom rail and injectors set you back?

I need to think about an upgrade, at the moment my 740's have about 46 psi base and 50 psi when the pump steps up!

E85

Definately considering it Adrian.......After going for a ride in your beast it has got me thinking maybe in the new year we can sort it out with my current mods if your keen.

Still running BP Ultimate and Adrian is wanting to tune E85 (hence the post) in the old girl i'm just a bit put off with availability of the fuel at the moment

The torque has jumped from 6200 to 6800 tractive effort so definately a nice push in the back.

I may have not followed this thread properly but, has the block on Lee's car been cracked opened?

Has the head gasket been changed?

Still standard motor (unopened) running a nice safe tune.

Hey mate. Cool, I was 99% sure that was the case.

That's still the plan.

The rail is a straight swap between another BW customer - he needed an 11mm top-feed and I a 14mm. Worked out nicely. My old rail usually retails for ~$250 from James at Nisspeed - comes in either 11 or 14mm. James has one of each sitting on the shelf, I saw them on Saturday (13th Dec).

The injectors came through a workshop owner mate of mine, he ordered them in for a customer and then they decided to go for 1000+cc stuff. He said ~$80-90ea, RRP is usually ~$100-120. I've had the injectors for a few days and I'm just about to go and give him the dollars now, so I'll find out the exact price shortly. Either way $100-120 isn't a bad price for a new top quality injector.

$250 for a rail, $600-720 x 6 injectors, and some fittings and fuel line and you're good to go, be it 400hp or 1000hp. A set of direct fit Sard/Nismo/HKS etc. Side-feed injectors may or may not be cheaper, depending on the AU-Yen exchange rate at the moment.

I see you had some good results with E85 RB25DETS2.

323rwkw out of the .6 rear, std top end, std exh. manifold. Damn impressive. :)

Yeah thanks mate the thing is a completely different car. I would like to think that i had something to do with it but in reality 180or200 tuned the old girl and put me on to the fuel so he deserves all the credit. Very happy with it to say the least. Standard airbox also might be starting to choke it a bit.

Well done Lee & Adrian.

Can you list the mods that were required for the changeover?

Cheers Pete,

The only mod required was a decent fuel system to support the extra flow needed and a decent tune. I will be changing my Fuel filter after the first couple of tanks just incase it has picked up some crap.

    • If as it's stalling, the fuel pressure rises, it's saying there's less vacuum in the intake manifold. This is pretty typical of an engine that is slowing down.   While typically is agree it sounds fuel related, it really sounds fuel/air mixture related. Since the whole system has been refurbished, including injectors, pump, etc, it's likely we've altered how well the system is delivering fuel. If someone before you has messed with the IACV because it needed fiddling with as the fuel system was dieing out, we need to readjust it back. Getting things back to factory spec everywhere, is what's going to help the entire system. So if it idles at 400rpm with no IACV, that needs raising. Getting factory air flow back to normal will help us get everything back in spec, and likely help chase down any other issues. Back on IACV, if the base idle (no IACV plugged in) is too far out, it's a lot harder for the ECU to control idle. The IACV duty cycle causes non linear variations in reality. When I've tuned the idle valves in the past, you need to keep it in a relatively narrow window on aftermarket ecus to stop them doing wild dances. It also means if your base idle is too low, the valve needs to open too much, and then the smallest % change ends up being a huge variation.
    • I guess one thing that might be wrong is the manifold pressure.  It is a constant -5.9 and never moves even under 100% throttle and load.  I would expect it to atleast go to 0 correct?  It's doing this with the OEM MAP as well as the ECU vacuum sensor. When trying to tune the base map under load the crosshairs only climb vertically with RPM, but always in the -5.9 column.
    • AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.
    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.
