Rich's NA-T

Speak to Biebs on here mate, whatever Clutch he's sourced for his 5 speed after an N/A-TT transplant, seems to be pretty darn good and I've been in his car and he gives it a hell of a lot of abuse, :p but he's only running stock boost around 0.8bar

 

oh and I would suggest NOT getting a paddle clutch, you'd blow the W58 to pieces.

 

 

Cheers for the heads up mate, I shall drop him a PM :)

Rich, Chris Wilson on here does uprated NA clutches that are possibly still suitable for NA-T - drop him an email. Details are here:

Or this this one popped up for sale recently along with the flywheel?

Im in the same boat regarding clutch

 

The spec stage 3+ from Whifbitz looks to be the daddy, higher torque rating (430 lb/ft) combined with road friendly..comes with the higher price tag though

 

Im pretty much set on the stage 3 (6 puck sprung hub disc) which ill be ordering tomorrow :)

Cheers for the heads up mate. I'm quite interested in the Spec Stage 3 for sale that you've posted a link to there. I'm just trying to decided whether to bite the bullet and buy the Spec Stage 3 + instead though. Hell of a price difference but the Stage 3+ does seem to be "the daddy" as Berg put it.

Careful with the Spec clutches. I broke mine in after 1500 miles and had a little play around a couple of times. After a hard drift this happened -> http://www.mkivsupra.net/vbb/showthread.php?254266-Supra-Spec-Clutches I was only NA too! Spec said they were going to refund me as it was a stage 3 and should of taken twice the power of what I was running. Never heard from them after that!

Hmm thanks for the warning! I like to deal with companies with good customer service and that sounds far from it!!

 

Any idea how the Competition Clutches are? or are they W58 killers :D

Just received my injectors :)

 

Precision 550cc. Will need some O rings (I've got new OEM injector O rings, hoping these may fit?). These should give me some room to play with once it's mapped.

I'll be looking to have these ultrasonically cleaned and flow tested, so if you have any recommendations then please shout up!

Nice no resister pack needed for you then?

 

As far as i know Chris Wilson does ultra sonic cleaning

I have been told they are high impedance so no resistor pack should be required. To triple check though I shall test them on a multimeter and note down the impedance. It should rule out any hiccups when it comes to mapping touch wood!

 

Cheers, shall give him a bell next week :thumbs:

I've refitted the head I rebuilt along with ARP head studs and OEM TT head gasket to make for a more boost friendly set up. All 14 threads in the block were re-tapped and cleaned up along with all the head studs cleaned up prior to fitting. Ended up ordering the correct tap through a friends work as the previous one was pants. I've also fitted my modified TT oil return to the oil pan and painted the whole lot up ready to refit. Mating surfaces of the oil pan also cleaned up to help make a good seal. My Toyota FIPG turned up yesterday as well so I can get on with fitting the modified oil pan asap! Distributor and cam pulleys also painted and ready to refit.

 

The correct tap:

So clean! Just so so clean!

 

Haha cheers mate! Must be honest and say it's taken longer to clean up/paint/polish parts than anything else so far :D

 

Home straight now though, got a long weekend now so going to start building the rest back up and fit the manifold, turbo and such like.

Have you fitted an elbow on the turbo compressor housing outlet? It's a right PITA. I haven't and melted through a couple silicone joiners already.

 

I've shaft play slightly so won't be doing it until I get a new turbo. Definitely worth doing 100%.

 

I can imagine the cleaning bit took ages. Credit really does go to all the guys on here who follow this process. Your going to end up with a stunning motor for sure.

 

What turbo you going with?

I haven't mate, was hoping to get a 90 degree elbow welded on but I need to find one suitable first and then find somewhere to weld it for me. I'll take your advice though and have a search now for one.

 

I've got a XS Power T61 sat here which I picked up for a good price. I would love maybe a Holset HX35 or similar but don't want to run before I can walk kind of thing and also budget isn't unlimited unfortunately! The T61 looks in good shape though so hoping for some semi decent results with it :)

 

What would you say is safe power on 440cc injectors? I've got some I purchased here which are meant to be 550cc's but I think they may be 525cc instead. Not sure they are going to work with the stock intake manifold though so may drop to 440's unless anything else comes up.

Why do you think they wouldn't work with the intake manifold? Fitment should be for the rail and runners mate.

 

Usually people say 1cc for 1hp is a good match with a bit to spare. Jekyl years ago had 385bhp on stock 330cc injectors. I would say with 440's that 400+ is a good target to aim for.

 

On stock ignition you start to blow the spark out after 400hp I've found.

 

If you have 525cc and lowered compression you should aim for 500bhp. The extra 50cc shouldn't make a huge difference. Anything about 500hp people usually have much larger injectors. I think 7##cc is the next bigger GE injector I've seen. Probably some 6## out there but I wouldn't bother.

 

The dizzy is 'apparently' good for 700bhp (US forums and a few UK tuners) BUT I've had problems at 400bhp so I'd look at upgrading your coil if you want much more than 400. David P has a nice igntion setup. HKS twinspark etc. I'm visiting him soon, I'm going to grab details on plug fitment etc and how it can be matched to the NA. I'll keep you posted on that if you want.

 

The T61 should do you fine for a decent NA-t. Mines gone 2 years and still fine.

 

For all your effort, and your gearbox, I'm surprised your not aiming for more?

I'd probably be best sending you a picture to show the issue with the injectors but basically the end of the injector doesn't fit into the hole in the lower intake runners. Also the clips are wrong for the stock loom and they have no pigtails with them, that's no biggy really though, easily rectified. Long story short the seller has been great and it's all sorted now. Just need to find me some other injectors.

 

Regards power then I have no real idea what to aim for. I'd like a nice comfortable 400bhp but anything over that is a bonus. I will definitely be looking at ignition system upgrades, so if you could keep me updated that would be great :thumbs:

 

My gearbox is a W58, I'm not one of the lucky owners of a later model SZ-R graced with a six speed box. This brings me onto the clutch, are you running a Stage 5 Competition Clutch? I'm sure I read that you were. If so, any feed back as that's what I'm looking to go for? :)

 

Cheers for your help and advice mate, it's appreciated.

I've just replied through PM so sorry if I repeat myself!

 

Component upgrades should be around your power target. 400 is a nice figure for a stock NA-t on w58. I've not seen anyone do it on stock injectors though. 440's is the lowest I think sensible considering for 400 lyes.

 

I've a stage 5 clutch and lightweight flywheel.

 

Sadly something in mines broken, so perhaps a clutch and flywheel for sale :cool:

 

The US sell some nice 2JZGE injectors but Chris Wilson would be where I'd send them to get flow tested.

 

If my box has definitely failed, I'll more than likely be selling my 440's.

Not a huge update but I have refitted the cams, cam pulleys, new cam seals, Toyota FIPG used for the no.1 cam caps, engine hooks fitted, cam covers painted up and refitted along with a couple of odds and sods like painting up my engine covers and fitting them with all new Toyota gaskets :)
