Interesting project. I got given a link of a shop in melbourne that does itb work by a client of mine who builds racing mini's and plays with itb's fairly frequently. Hope it helps

Avoiding the other stuff. NIce - be nice to see how it all turns out. I found out how much easier it is tuning Carbys on Race 1600cc Open wheeler is then Using a ECU and TPS mapping. One screw adjustment here and there. so easy. Nah 4D mapping is a big help. Havn'et used the Link setup. Havne't had anyone I know use it yet. My only wonder is - How you plan ot feed it Air ? Easy in Rwd clubmans and open wheelers etc but in the FWD layout - What are planning - reverse vacum feed or just open? I just wonder. It's something I just always wonder about. Because I know the amount you can loose by creating some sort of plenum chamber to feed multis Sometimes not worth it in the first place. Not that I think you would even bother unlike in this case. This motor Yes LS1 It got some intake covers made up with ducts to feed it. Still makes on 600HP but has been have trouble since gettign new covers made up to feed air into the Multi throttle bodys. I'm not surei f it was tune or to do with the intake feeds |

i looked at a twin carby setup, another person in NZ is doing his n/a build with carbs instead, look good i must say, but he still hasnt told me much about his setup, hes using a B6 carby dizzy for vacume advance etc thats all i no,
air feed will be direct from the engine bay with sock filters if thats too loud,,and it prolly will be so; i'll hack up the factory air box that toyota created with the factory velocity stacks from toyota (stab stab take the bait, you no you want too) and use that with a feed from a cold air box in the front Dam lov'n that LS1 setup nothing sounds better than a N/A ITB V8 setup do a youtube search for the NZ targa car one...1U v8 DAM, sends chills when they rev it

yeah I want to get more photos of the ls1 it's in a WB ute with full Caprice add ons and alot of modern things like even Reverseing camera custom Tanoue cover (SP what ever they call them hard shells)
I think as long as you feed it plenty of air if you have to box it should be fine. If you have the space twin feed it ? IMO - any N/A motor should have individual TB and nothign in the way of it. maybe old school Ford Cosworth F1 mesh but that's it. |

Lawsy you dont want my engine.
i only did this as i brought the Toyota and no sense having two turbo cars..it gets expensive really fast. ANYways some more spy photos! Yes i no they dont "Match" perfectly but thats what Ali-epoxy filler is for...still should have got some Blacktop ones thou..a bit bigger and less likely to choke the motor at 7500k

Not trying to hijack your thread but heres some photos of my ITB setup.
First one been the adaptor plate before fitting the manifold And then with the manifold fitted And last with the plenum, I wouldnt mind getting rid of the afm and just running trumpets with filters but all in good time lol Last edited by mazdaguy01; 03-03-2008 at 06:42 PM.

looks good
how thick is that adapterplate? i tried to have mine on a 7 Degree angle, but the flange isnt thick enough to do so doesnt look too bad on a FS-DE engine, how does it go anyways?

Um 25mm from memory, I wouldnt have minded a slimmer one but this way it clears the bolts for the cam cover and such and let me have a smoother change from the toyota port to the mazda port shape.
To be honest it goes like the clappers and sounds awseome but still havent sorted the ecu so apart from a few spurts around the block I havent done any road tests yet. 2k idel just isnt fun. How are you for firewall clearance? Mine is awfully tight with the plenuim fitted. |

Mate that looks really nice, maybe someday i might get sick of Turbo's and build me one of those, but like you said, all in due time....what do you mean by "goes like the clappers"?...does it accelerate crazily into the redline or what?...tell us some good points about the NA build you guys are doing?...are these things anything like the VTEC Honda's i see fangin round the place?...

Please tell me you're going to get some extractors mazdaguy01, or that you already have some and that the picture above is before installing them..
Otherwise there's not much point to all this, as with an NA build up one of the most crucial power makers are your extractors... I'm fairly sure you already know that, but just incase I thought I'd post up anyway... And dave, I have a SOHC. It is so damn frustratingly slow that It nearly brings me to tears (and I've got a good set of extractors, exhaust, I run 98 fuel because I've advanced the timing, good leads, plugs and whatnot, good intake setup and compression is good, very good considering how old it is); its just painful. |

Sorry zappy65 goes like the clappers=It accelerates so much faster, its about the same sort of acceleration that I get from a 50hp shot of nos... The power gain would be no where near that mind you. The vtec motors have a hit of power as they get up into the higher rev ranges, by changing the manifold we lose the vcis system which is a varible restriction in out intake manifold, which gave somewhat of a similar effect. But this means more air all the time. Of course not as fuel efficient. So unlike the hit of power from a vtec motor this is a more constant build of power accros the rev range.
Correct me if im wrong on this..... Lawsy im still getting the system running smoothly then im looking at lightend flywheel, extractors and ce as well as maybe high comp pistons and possibly look at upping the nos for some added poke. |

The VICS system is more for torque at the lower end and to provide effectivley two inlet runners.
Same sort of thing on 4L falcons etc. In a boosted application - remove it. The ultimate N/A for non varibale camshaft setup is have both. A short for helping larger cam shafts and long for air speed in the lower end. It's a bit like - dual plane versus single plane manifolds on a V8. Dual's are shorter but due to desgin give more mid range, with some loss in the top end. a Single is straighter and more direct air flow in so it's all mid to top end. If oyu could seperate the VICS , by haveing quads on it feeding righ into it and with the right cma shaft application change over just on when the camshafts becomes efficent. you could have very strong bottom end with a real wack at the top. The question is what camshafts are you running with this quad setup? |

VICS is a swear word for me now. Carless for 2 weeks. After borrowing a 121, a Getz, a VY Commodore and a Lanos, I really miss my car even more.
Those ITBs look very interesting. You may even be able to sell a few kits once the bugs are sorted out. Here or in North America on the Mazda Forums where there are some fairly serious NA builds happening. Please keep us updated, maybe with your own build thread? |
