i was behind you that night 09one ,i saw it all , was a good run. i was in my vl , but met up with a few of the redcliffe boys that night at aspley.
-
cams , once dialled in , and matched to your other components (turbo , boost , computer etc etc) will make a world of difference. definately grab a set of adj gears too.
-
try Tighe Engineering (Tighe Cams) get some cams ground to match ur turbo , computer , boost selection etc. grab a set of springs too while ur at it

roy i weighed a rod , endcap , rod bolts , piston , gudgeon and c clips all as one unit , and the weight was 1.25kg. if u want i will seperate them , and just do the rod and piston alone. cheers
-
it is best to keep the machining of the cyl walls to a minimum if ur planning running high boost , 20psi plus. though there are plenty of chaps out there with 1mm overbore and are running high boost.
-
yeah im just a SLO-3L(itre) aswell
-
a little off topic , just curious i am a firm believer that nissan is best , in terms of quality of parts etc i have always used nissan head gaskets in mine and other vlt's in comparison , what are hks and tomei gaskets like etc? any of the hipo skylines use them , mario etc?
-
hahahahaha davey - is the gt35? on ur car yet? ps does ur car get wheelspin i quite enjoy leavin $70k hsv's etc for dead , not coz they are fast cars , but coz the silly bugger has spent so much money on a shitbox. gotta love beating skylines too hehehe
-
base maps on any comp are there to get the car started , not to be daily driven on. do u feel that the car is performing well , or is it a bit more rougher than before the comp was installed? as said above , get it tuned asap
-
agree totally any of you serious boys index ur plugs at all?
-
joel i am aware and i understand what ur saying just that we cc'd it correctly and found a slight variant of what we have read elsewhere. looks though we will use it as is , we figured that half a point of comp wont be to detremental.

sydneykid thanks for ur advice mate , i respect what u say , i have read many a response from u and u seem like a very knowledgeable chap i will let him know the points u have made. my mate works for tighe cams , he is an engineer , i dare say he did his calculations correct but who knows. anyway , we planned for a cr of bout 8.2-3:1 , while using custom zorst manifold , gt35 or 30/40 dunno which one , custom inlet etc etc , anyway i will see what he says , also will try and grab the specs and post em up thanks again andrew

just a note to some ppl a mate has just done a lot of work building his engine for his vlt its a stock n/a 3l bottomend , fully prepped though , and a 25 head , vct welded up. now it was made apparent to him and many others that bolting a 25 head to stock vl bottom would result in approx 8.3 comp , well after many hours work , we cc'd it all and it turned out to have about 64cc , which gave a comp ratio of bout 8.8:1 , too high for a performance engine as timing would be stupidly low. i know most ppl using this great thread are using forgies aswell , but just check out some things before going ballistic on ur new engine. anyway we are now going forgies for this engine , etc etc etc good luck to all who do the conversion , its a top idea andrew
-
they are supposed to be the ducks nuts so i hope that everything goes well for ya. it also depends on who sets up the computer , how much fuel is goin in on cold etc anyway good luck mate
-
microtecs are reknowned for having a poor cold start just gonna have to cope with it , a little bit of fiddling and u will get it better though. i have numerous mates with microtecs in their vl's , all of which suck on cold starts , i have an autronic and its wonderfull. bare with it though
-
hehehehe what a funny thread not all vl turbos make this sound anyway as described earlier , if u want flutter , ditch the bov , throw a pod filter on , and after a few months , rebuild ur turbo. flutter sounds cool , but is also damaging to ur turbo in the long run.
-
if its gotta go asap how neg are you on the price pm please andrew
-
it could be done with the block in the bay , but u will have to take almost every ancillary off , inlet and exhaust sides , thermostat will have to come out as there is a welsh plug behind it (i think so on that engine anyway hehehe) best to do it outta car may i ask why ur doing it? one rusted/leaking?
-
i have a mate who is making a smidge over 350 on his sr with a tdo6 , might be worth thinking about. and it has a bit more left in it too. as for the .63 or .82 , being a small engine the .82 may be a bit laggy , its similar to a few mates of mine , they have opted for the .82 over the 1.00 or 1.06 whatever it is , to suit a vl turbo. lag and power was rather different between the two , and thats on a 3l engine , so maybe the .82 may be a bit big for ur intended application. im quite sure u will reach ur hp level , with either turbo though.
-
www.are.com.au cant go past them , for flow and cooling effientcy. does cost a bit from there , but quality difference is amazing. do it once and do it right
-
pfc would be a better choice than a wolf.
-
is that 300kw at the engine or wheels. i dont think it will reach 300kw at wheels , and if he is using the standard computer , it wont have the ability to run a fuel system , to handle 300rwkw. with that combo , id invest in a better fmic that the supra one. should push 330hp at the wheels or so , good luck with it.
-
hahahaha i like ur style:D the ticking whilst cold , as said above is the lack of oil in the top end so lifters will tick. not too sure with skylines but in the vl , hydraulic lifters always after years of use seem to tick , and take a while to "pump up" when cold. a water pump most likely wont make noise at idle , it is more a load thing , hold it at 3k revs , in neutral , and listen for a definate clunky noise , more evident than a tick noise. sounds similar to a thrown big end bearing. injectors make a constant tick tick tick , be it hot or cold , day or night.
-
wont be aircon id say its just lifters could be oil or water pump injectors tick does it happen moreso when its cold , then its a very good chance its just lifter. is it at idle or under load/speed

try M R C Dyno and Performance he used to work for some nismo boys , he is a wizz with skylines and vl turbos. he did my autronic , he is a horsepower heroes winner , tunes his own shit etc very nice bloke
