It is easy to ride with you do not say never, but you fall ill the acceleration impression of strange dimension and it is being attached.

steb9780 Posted November 15, 2006 Share Posted November 15, 2006 I think this is how the Skylines are setup. Yes I believe they are, I have bored some out before now for RB motorsport. They get the standard ones bored to allow more airflow. I think the big power ones use custom plenums, I have done some flanges to make a custom plenum for Keith Cowies car.

It's a bloody nightmare changing the inlet manifold and throttlebody gaskets on one of these!! Took me bloomin ages!

Jackal Posted November 15, 2006 Share Posted November 15, 2006 That NA in the first pic looks fooking naughty with the throttle boddies might have to consider that instead of going down the tubby route. Does any one know what sort of power it would be putting out? Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted November 15, 2006 Share Posted November 15, 2006 Some absolute cracking translation on that... Thats some funny shit! YSR are well known for the Chaser stuff, I didn't even know they did Supra stuff... good find Nic Gaz. Quote Link to comment Share on other sites More sharing options...
Cable Posted November 15, 2006 Share Posted November 15, 2006 However 6 butterfly's are possibly more restrictive than 1. Not really, you get a greater area with six smaller throttle bodies than one larger. To try and equal the individuals throttle bodies area with a large single the air speed suffers losing power on an N/A engine...

Kranz Posted November 15, 2006 Share Posted November 15, 2006 Individual throttle bodies allow much greater flxibility in designing the intake system for performance. It allows: The intake length to be optimised for port velocity & resonance tuning, increasing volumetric efficiency. The injector orientation and distance from the head to be set to give max power rather than emissions. An injector mounted far from the head can normally cause fuel drop out problems at low throttle openings, but with an individual throttle and an injector mounted further up stream of the throttle the injector can be aimed at the throttle, breaking up the spray at low throttle openings but also allowing good fuel to air mixing at wide throttle openings. The throttle orientation can be used to bias flow into the port, changing swirl characteristics and increasing mixture homogenisation (more uniform air/fuel mix across the cylinder) And some other stuff I can't remember!

colsoop Posted November 15, 2006 Share Posted November 15, 2006 I remember my younger days when hot hatches were still king . One of the guys had his peugeot modified to run an mi16 engine with throttle bodies and the sound it made was amazing Quote Link to comment Share on other sites More sharing options...
jagman Posted November 15, 2006 Share Posted November 15, 2006 once upon a time tuning engines involved adding more carburettors or larger carbs in order to flow more air into an engine as its the maximum airflow that will dictate the maximum power,with the onset of fuel injection the throttle body replaced the carb so by adding multiple bodies you increase the area from a single one so you flow more air,there is a place in manchester that can supply throttle bodies and manifolds for most cars and various sizes available im sure they would do one for the n/a supra --www.dtafast.co.uk Quote Link to comment Share on other sites More sharing options...
Kranz Posted November 15, 2006 Share Posted November 15, 2006 im sure they would do one for the n/a supra --www.dtafast.co.uk But how much??? Wouldn't NA-T be a better option? Individual throttle bodies is one expensive mod. And I bet they're a bugger to set up & balance Quote Link to comment Share on other sites More sharing options...
ChrisSZ Posted November 15, 2006 Share Posted November 15, 2006 Hey! I remember playing with carbs - got quite good at balancing multiple carb set-ups :) The first thing we used to do was fit larger jets and a free flow filter for more fuel/air in. I too would be interested in the costs involved in fitting TBs to an N/A. I assume one would need a mappable fuel computer to make the most of them?

steb9780 Posted November 15, 2006 Share Posted November 15, 2006 I believe these are good for throttle bodies and custom stuff to make custom manifolds and plenums. http://www.jenvey.co.uk/ This is where my mate got the trumpets for Keith's skyline. He said they use them quite a lot. Quote Link to comment Share on other sites More sharing options...
Markie Posted November 15, 2006 Share Posted November 15, 2006 Good power for a SEQ TT setup. Thought none ever had a go at making them... Would be a good buy if they work well. Quote Link to comment Share on other sites More sharing options...
Chiefgroover Posted November 16, 2006 Share Posted November 16, 2006 Whats all this theory that big sequentials will stall each other etc? pphhhooeeyyyy!!! I tell you, bring them on, bet they are a fab easy drive, and a real bugger to fit! Me will test for Nic, soon as he sends me the kit for free!

Thorin Posted November 16, 2006 Share Posted November 16, 2006 The dodgy translated info on the "big sequentials" ≪JZA80 TD-05 sequential twin turbo ≫ As for this 2JZ depending on the thing which adopts the sequential control of the turbo, Low from the revolution, 2000rpm it becomes full boost. At the time of high revolution extracting 600ps by changing to the twin turbo actualizes. It is the manual mission, it is possible to be able to send also the [te] fast, not to be sequential but With [otomamitsushiyon] in simple 600ps specification when starting the extent which is defeated to also the automobile lightly it is to be slow. To catch beginning the boost does not become above 4000rpm how. As for the [otoma] car there being " stall revolution " Once, there is a quality that rpm above that does not rise near 2500rpm. It is not to be able to decide start dash because there is this. The giving [gu] [re] [niyutora] (N) from as for the how thing which shifts the gear please do not do. The mission breaks into pieces. The owner because there is the desire that we would like to run fast pleasantly even with [otoma], is to have become this kind of shape. Actually when [zeroyon] it tries measuring, it becomes the engine which had the capability above 12 seconds flat, That way, it became the way which above 300km can be put out. It accelerates easily with the how heavy body. It is by the [otoma] car! You call also the giving [gu] [re], but it is the [otoma] car. Specifications YSR original TD05 sequential twin turbo system YSR original version trust e-[maneji] (sequential control) YSR [orijinaruhaikonpu] specification YSR original port & combustion chamber processing YSR original strengthening mission HKS256° camshaft Section balance taking In addition large number 600ps So it uses the e-manage for sequential control?? (e-maneji?) Quote Link to comment Share on other sites More sharing options...
Ark Posted November 16, 2006 Share Posted November 16, 2006 Note that it uses 256° cams - with a longer duration and some decent management, you should be able to go beyond 600 I should think. Quote Link to comment Share on other sites More sharing options...

Chiefgroover Posted November 16, 2006 Share Posted November 16, 2006 Mate, it was only 2 weeks ago when I posted asking this very question of whether big sequential setups exist I came up against a brick wall of relplies telling me it cant be done........ I thought the issue was getting no.2 pre-spooled before it brought online ?? I asked this 3 years ago, and go heckled for mentioning such a thing. Despite Tdi having done it, and offereing it as a product at the time, I still got snapped at for mentioning it, even from one chap who runs a tuning company who really got nasty in his reply just cause I asked. Well........I'd like one of these kits, and to take some of those people for a spin, see what they have to say then! Quote Link to comment Share on other sites More sharing options...
M4RK RZ Posted November 16, 2006 Share Posted November 16, 2006 I agree, I would want them too! - maybe the big single turbo guys are worried lol (I did I just take out a pin and throw in the grenade ...........tink - tink....... ) Quote Link to comment Share on other sites More sharing options...

To try and equal the individuals throttle bodies area with a large single the air speed suffers losing power on an N/A engine... I think 1 big pipe has a larger cross section than 6 small ones. All the other advantages are NA only. IMO. Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted November 16, 2006 Share Posted November 16, 2006 Individual throttle bodies main advantage is increased throttle response, on both turbo and N/A engines. Quote Link to comment Share on other sites More sharing options...
JohnA Posted November 16, 2006 Share Posted November 16, 2006 ...speaking of throttle bodies, I've got a friend currently struggling to balance his RB26 lump. I'd expect to find nipples and adjusting screws, but apparently there are none. The manual says you should use feeler gauges to check the throttle openings. Chris, is that true? How is it done properly then? Quote Link to comment Share on other sites More sharing options...
Ian C Posted November 16, 2006 Share Posted November 16, 2006 Mate, it was only 2 weeks ago when I posted asking this very question of whether big sequential setups exist I came up against a brick wall of relplies telling me it cant be done........ I thought the issue was getting no.2 pre-spooled before it brought online ?? Looking at that picture (and I haven't seen the bigger version because I refuse to bother signing up to some spamfest at imageshack in order to do so) there does appear to be some control mechanism in the plumbing that means it's not a simple parallel setup. I always maintained that issue #1 would be the packaging of bigger sequential turbos, but it looks like someone has spent the time and the money to fit it all in, so speaking as one of the naysayers, I was wrong on this front and happy to be proven so Issue #2 for me was balancing the spooling of turbo 1 and the prespool and cutover of turbo 2 to ensure more drivability than a simple single or parallel twin setup. If they have cracked that (and sadly we may never know) then it's truly an interesting solution. Interesting it seems to mention the E-Manage for controlling this, I can't really see how it would - the Ultimate might be able to with it's additional output maps though. So Suprash, you ordered one yet? -Ian Quote Link to comment Share on other sites More sharing options...
bondango Posted November 16, 2006 Share Posted November 16, 2006 Yeah YSR from Yokohama does some great work. He has built some hefty powered 1jz's over the years as well. Apparently his tuning shop is well worth a visit if your over that way. http://www.ysr.gr.jp/jzx100/taki5.JPG now if only there was a bigger version of this pic :-( Nic whats the price on his AP6 pot conversion just out of interest Quote Link to comment Share on other sites More sharing options...
