  1. yea second set of injectors on top of throttles is worth a few hp but having the room to set is the problem. Megasquirt extra code has teh mean injector staging system. Also with resonance tuning your almost always going to be catching the second or third reflection theres no basic all aplication formula. Used this street dyno before which measures the time between spark pulses to tell if acceleration has been improved thus giving you a basic as dyno plot. works mean for seeing if trumpets or your tune change the power. Can give close to real world figures if you accurately put in the weight, drive ratios etc tis a mean tool seen guys dial in cam timing with it got it pretty bang on

  2. gave it a fresh matty b job for nats was finished the day before but came up sweet ( cheers to the guys who took pics at nats)

    Also after not realy liking 1gge's Ive ended up with two 1gges a 1ggze and a spare head.(the pics are a shambles)

    A filthy 1g sitting next to my 1jzgte

    another filthy 1g

    and a 1ggze with the spare head on it notice the hooge ports so theyve got some mad tvis stz ala 4age

    plans are to chuck a 1gge in it and drive it, and rebuild one of them with a planed head cams etc. Also picked up some more itb's

    I have a couple of megasquirts (diy engine management) sitting around so will chuck one on and go individual throttles. cad'd up some flanges and mike-e's getting them laser cut then a mate is going to weld them up

    so basically hoping to have a 1g in and running on itb's and megasquirt by next track day. which should be pretty easy as its all bolt up and I have all the parts

  3. ^ think your confused there w57 was just the next box after the 55 with slightly different ratios (5th gear only) Ive seen them in celicas and cressidas with a range of shifter positions. there is a w56 and 9 that came behind diesels and vans

  4. well dude with a 1jz has done 40,000kms in a 1500kg car with 240kws on an unknown condition box. some of the higher hp guys destroy them but jag = fine. Im doing a 6 throttle conversion just need to copy that * 2 haha but depends on your port spacing and angles so could be easy/hard. Start collecting those 20v throttles you'll need 4 sets as you cant use the end ones

  5. The gear box will be by far the weakest part of the car after the conversion. So i will have to nanny it/nah :P

    your running a w5* aye? people run 200kw+ at the wheels through these no worries, I think you'll be fine

  6. ^ I agree with you there on some engines have quite decent cast manifolds but the 1uz ones are literally a log. Pretty sure theres dyno results on the soarer forums of pretty crappy extractors giving gains. Anyway havn't found those pics yet but will keep looking

  7. Aren't they all real crappy logs?(think theres more than 3 if you count the real new stuff). Ive got a few pics of some in cressidas etc where its real tight will try and find them. Equal length is ideal but in reality anything is better than the stockers. Also 8 throttle bodies please

  8. Hmmm yea intercooler is still desirable as compressing air generates heat tis basic thermodynamics. Crazy v8 setups still run intercoolers usually water/something colder sits under the super charger. I think an sc14 is a pretty asthmatic charger its runs out of puff pretty quick on a 1ggze. Also yea throttle after the blower = just run a couple of bov's to vent the pressure, seen a few 4agze's setup like this its stops the lag of the engine sucking up the air in the cooler piping when you throttle off. But gives you crazy throttle response with that boost waiting there basically pushing the butterfly open!!

  9. I think the mini would be the same deal as uncle jake with the 10.5:1 most 2v heads are pretty closed up where modern 4v heads are relatively open and arn't as prone to detonation. Yea and 12:1 is pushing it but as said above with bigger cams static compression is lower anyway
