HI Eddy - which of smithy's are you getting ?? The stage 2-3 roller bearing jobbies??? :dance: :dance: :dance: Regards, alex

:slap: so my english aint too good can i asume that since the car has been running well and i'm running standard injectors that the mines ecu would be set up for standard injectors. the inference of last weeks conversation was that if the mines ecu was set up for 555's and you actually ran standard injectors the car wouldnt run right. Regards, alex

ok - so can i asume from this that the mines ecu is set up for 370 injectors because thats what it is running on at the moment. and if the ecu was set up for anything else the car wouldnt run right. Regards, Alex

oooohhh - ill take a look - cheers baggins

Ok OK so call me nerd ....but where does the number plate go??? p.s. looks excellent - might have to get me one of those :D Regards, Alex

just bringing it to the top - anyone else offer advice??

I'm about to take out my mines ECU and replace it with a custom map from SE - does anyone out there know how to tell the specification of the ECU i.e. what size injectors it was designed for. I'm thinking about selling it but i need to make sure i know what exactly it is. Regards, alex

HI Mac, does big turbos = quick 1/4 mile times i really dont know but to my way of thinking big turbos are better for hard acceleration in 4th and 5th - considering a really good gate speed for us would be 115 and we can do 100 in third do big turbos = a quick 1/4 mile time. Its going to be an interesting year next year :D Regards, alex

It Must be MAC :slap:

well that should be quite easy - you obviously dont want to use carbon sivs because of the pressure swing characteristics, but a couple of nice big in line membranes should do the job however your still going to run into the lag problems again because you still need the volume of air flow which would mean bigger turbos. What might me quite interesting is mounting a couple of membranes onto a ram air scoop which would enrich the charge air to the turbo - that way you dont need bigger turbos to get the air volume - you just increase the O2 content. hmm - its a possibility - but it would only work at high speeds like a ram jet :D Regards, alex

ok i had to guess at mine because its never been tested but i'm aiming for 400-450 if i'm not there now i will be one day :D Regards, alex

your not wrong there - those tuned pulsars are unbelievable - everytime you get in one its like having pastic surgery on your face :rofl:

I for one have found the debate about turbo size interesting and its one of the things i love about the zed - that for not huge amounts of money people can completely re-model their car to get what they want to achieve out of it. so i say carry on with the debate and for those who have the balls and money to try something different (whatever it may be) good luck to you. Well i've come to a revelation tonight (after 1 bottle of wine) so it might be *****x but what the hell. my views on turbos have been widely expressed and it basically comes down to the assumption that a responsive 450 bhp car will be quicker to drive day to day and maybe even in the 1/4 mile than a 600 bhp car. What evidence do i have for this - NONE - its just my gut feeling. This is why i opted for smithy's roller bearing turbos and have been tweaking my zed for responsiveness (fidanza flywheel vernier pulleys, custom ecu map etc). The one thing that bugged me was seeing smaller cars running bigger turbos. The 300zx turbo upgrade at SE is the T28, which can be found on the 200SX S14 and the pulsar (N10 i think). Well to my way of thinking i couldn’t understand why cars with smaller engines were running bigger turbos. Only tonight after 1 bottle of wine did i realise that these cars were running bigger engines that the 300zx. Because we run a V6 twin our effective engine size when looking at compressor maps should be 1 1/2 litres per turbo. So.... I am more convinced than ever that the way to go to get a quick car is not to bolt on ever bigger turbos but to look for efficiencies. Maybe driving a twin turbo car has made us lazy and we should look to the likes of the people tuning NA cars for performance increases. If you like this post and it increases the debate then good - if you think its a load of *****x then ignore it :D Regards, alex

interesting that the previous owner changed from the16g to the HKS GT 25 - still £700 for a £4,000 piece of kit shouldnt be sneezed at .

hi mike, the t28 that SE use is the TB2808 - garretts official figures say that it is rated for 300 horses - twice that being 600 horses and the ratings are based on a 2 lite car. this being true i dont see why twin TB2808's shouldnt be able to put out 600hp. looking at the specs your 18g's put aout about 25% more air than a TB2808 - do you know what this works out to in bhp - surely to god it cant be pro rata because that would rate twin 18g's at 750 bhp omfg i did notice though that the 18g doesnt reach peak efficiency until 5,000 rpm so it will be really interesting to see your torque curve and see how it translates into a 1/4 mile time. I'm trying to achieve 450 bhp on my mega fast spooling TD turbos and i'm betting i wont be far behind you on the 1/4 mile. If I am, I will have lost and i'll just have to fork out for some bigger turbos. Next year is going to be very interesting :dance: Regards, alex

16-17 psi on stock turbos - before that on mine p.s. nismo 555's being fitted on Monday :dance: Regards, alex

easy tiger :confused: I am of the same philosophy as stu - i am running stage 2-3 T28 hybrids with stock internals at 14psi. I already have an upgraded rad and intercoolers and i want to run at higher boost levels. I quite expect my engine to go bang when i increase the boost but whats the harm in trying - if your fully committed to building a new engine anyway, why not see what the existing one can do? Regards, Alex

ouch - doesnt sounds good

this is probably a long shot but my daily drive is an old astra. About 9 months ago i noticed that it was sounding rough - like tappett noise. shortly afterward the cam belt broke. Could it be as simple as it needs a 60k service - can you tell what state your cam belt is in? Regards, alex

I've just bought a sony cybershot P12 - furkin unbelievable 5 megapixel camera that can fit in your shirt pocket and take deent movies for less than 300 squid. oh sorry never heard of trust - i guess this post doesnt help much then :D Regards, alex

looks to me like a cold morning sound to me like tappets - when did you last check the coolant level ? Do we have a group buy on a therapy session ?? :D i hope it's only minor Regards, alex

oh ok i'll go for the food anyway :D

jeeeez - there must be a better car park - ok food was good - but if you get any bigger turn out we're going to be parking in the car wash/valet place not that some didnt need it :dance: :D :D :D Regards, alex

hooly shit - biiiiiggggg boooooobbbbiiiieeees! :D
