stevo_gj Posted June 13, 2008 Posted June 13, 2008 im so confused, is the car for sale or just the engine? >< Quote
24OZ Posted June 13, 2008 Author Posted June 13, 2008 guys i am interested in EITHER selling the entire running gear conversion (from radiator to diff) OR swapping the car for your 240/260Z coupe plus some cash Quote
stevo_gj Posted June 13, 2008 Posted June 13, 2008 sorry about that, exams has my brain all sore. if only I could get mum to lend me 8K I'd probably book a flight to inspect your Z tomorrow. As is uni student is a bad title to have when looking for good car loans. Its painful but i'll just have to wait until I go to do vacation work for Xstrata over the christmas holidays. I'll be buying the best Z I can get in feb next year, providing I can wait that long good luck with it 24Oz! Quote
stevo_gj Posted August 5, 2008 Posted August 5, 2008 thats seems ridiculously cheap! :o if only it was an SR20 and not an RB30 :-\ Quote
24OZ Posted August 5, 2008 Author Posted August 5, 2008 thats seems ridiculously cheap! :o if only it was an SR20 and not an RB30 :-\ just run the RB at half throttle,you'll never know the difference for a street car there is no substitute for cubes,even when it is turbod,torque rules Quote
stevo_gj Posted August 5, 2008 Posted August 5, 2008 just run the RB at half throttle,you'll never know the difference for a street car there is no substitute for cubes,even when it is turbod,torque rules haha, what kind of fuel economy do you get? be honest now! Quote
Scando Posted August 6, 2008 Posted August 6, 2008 thats seems ridiculously cheap! :o if only it was an SR20 and not an RB30 :-\ This is rediculously cheap! I don't think a lot of people understand all the 'extra' little bits and pieces you have to buy to complete an engine conversion. Stevo, buy it and spend the money you save on the engine conversion on a Corolla for a daily driver if you want to save fuel! Quote
stevo_gj Posted August 6, 2008 Posted August 6, 2008 i wish i could, but i'm living at home whilst at uni and can't have a second car! :'( also i want to drive my Z every day not just on weekends! Quote
RBZ 260 Posted August 6, 2008 Posted August 6, 2008 just run the RB at half throttle,you'll never know the difference for a street car there is no substitute for cubes,even when it is turbod,torque rules LOL thats what commodore and ford v8 boys think. till they find the hard way what SR20DET can do. and i still return 10L per 100km. stevo you be suprised how SR20DET pulls knowing it only a 2l 4 cyl. go for a drive in a sr20det powered silvia 200sx or 180sx. than do the same in a skyline and commodore. and tell me which one went better.keep in mind to have similar mods. BUT STILL THIS IS A GOOD DEAL. its preety much instant turn key power upgrade over the weekend. Quote
24OZ Posted August 6, 2008 Author Posted August 6, 2008 no doubting the SR20DET is a powerful option but you can't compare an RB30ET in a commodore to one in a 240Z..........trust me : as for mileage,better than the L28 with 2" su's that was in the car previously 2 reasons, 1-changed to 3.36:1 diff ratio as the car is so light that it wasn't loading up the turbo enough to get maximum boost in the first 2 gears 2-the MX7 5 speed has a good overdrive ratio in 5th of course the economy suffers if you want to feel the boost all the time,but the real advantage to a 3.0l turbo is that you can potter around like a granny off boost(as in daily driver) but when you nail it all the power is there.....kind of like having a daily driver and a drag car all in one (unlike a cammed/carbed/compressed NA that sucks fuel regardless of how you drive it) the motor runs safely on 91 octane unleaded but i always use premium anyway the motor is capable of much more horsepower with a more aggressive tune,bigger turbo and bigger injectors but it is plenty fast enough for what i am asking ,dollar per hp it would be hard to beat! i am looking at another 240z next week,so may end up repowering that in which case the rb30et will stay where it is and i will keep the car until it sells for $15,000 or just hang on to it. ps the rb30et Z was much faster than the boss 302 one ,pictured in my avatar,which i recently sold....and that was far from slow Quote
RB26DETT Posted August 6, 2008 Posted August 6, 2008 hi paul, out of interest how much did you let the silver car go for? cuong Quote

Administrators gav240z Posted August 6, 2008 Administrators Posted August 6, 2008 hi paul, out of interest how much did you let the silver car go for? cuong Hi Cuong, Good to see you signed up here. Interested to know how things are going with your Z. Its been a few years since we have seen it. Can you perhaps post some pics or give us an update? Thanks, Gavin. Quote
RBZ 260 Posted August 7, 2008 Posted August 7, 2008 Stock Specs: RB30ET 150kw/ 296 Nm of tourque SR20DET 147kw/ 265Nm of tourque thats close but dont forget SR20det all alloy and 4 pot= lighter in weight and in fuel usage. thats not even looking at what car it is in. I love them both dont get me wrong but i have a soft spot for the SR20DET. its amazing engine I had mine for 10 years and still hasnt been rebuilt and has been driven hard.10 years of 15psi boost 4 clutches 3 gearboxes and 1 diff. engine and turbo still OK and no signs of troubles. hence i got both of them SR and RB. but what to keep in mind the SR20det are still fairly expensive with the variable cam prob around 4k for a kit plus installation and modding required to fit it. which still makes yours a bargain for a drop in job. Quote
24OZ Posted August 7, 2008 Author Posted August 7, 2008 no doubt the sr20det is a great motor if you are limited to a 4cyl-even though i prefer the fj20det myself-but the extra 30Nm of the 3.0 turbo is delivered at close to 3000rpm whereas the sr20 peak torque is at 4000rpm,IMHO this makes for a better street car combination as it is torque that wins races not HP....if you race that is Quote
RBZ 260 Posted August 7, 2008 Posted August 7, 2008 this discusion prob be better in a post of it own. LOL BUT.................. also less weight wins races too proven by 1.6ton commodore with 7L v8 and Sh$#laods of torque vs nible 2 door sports car with 2 liters and 4cyl. while the commodore is smoking the rear end on the line im 2+ cars ahead of him. and he has no chance to even get to use the tourque where it counts. nothing beats their look afterwards with their head between their legs beaten by a milk and orange juice capacity 4 cyl as they commonly refered as Quote
620Z Posted August 7, 2008 Posted August 7, 2008 Yeah but think of the fun you would have smoking them up and the "G-forces when you finally get traction. Quote
24OZ Posted August 7, 2008 Author Posted August 7, 2008 the dual continues not fair comparing a sports car with a shopping trolley(even if it does have HSV badges on it) torque+live rear axle=smoke however with the Z's irs and 50/50 weight distribution they can transmit a lot of torque without braking traction which=acceleration i have a lot of respect for 4cylinder turbos and would never underestimate one in a drag race......i just wouldn't drive one on the street en gard Quote
RBZ 260 Posted August 7, 2008 Posted August 7, 2008 LOL WE should seriously make a seperate post about this otherwise we be here till cows come home. yeah well i got a rb powerd z and its fairly quick. but it does have a larger turbo so i cannot compare it to my s14.i had few runs against S15 and the Z wipes them. got two more 240z which one of them will prob get the SR20DET if i find a cheap front cut or wrecked car.the other one is going to retain its matching number engine. again. my whole point to the discussion RB has more tourque no doubt but for a light weight car like the S30 you do not need that to get of the line quickly. mostly it will end up in smoke im sure Craig knows all about that in his 350 chev powerd beast. also IRS dosnt help of the line racing as it squats down a fair bit and has larger camber= less tyre on the road = less traction.the large shopping trolley with HSV badge as you named it, still has IRS as well so they are in the same boat. Again if we have same car ie 240z one installed with stock RB30ET and other with SR20DET the SR20det one is still lighter and has enough hp/tourque to keep up and beat the RB just on the sheer weight saving.SR is one light motor. end of story. on the end it all comes down to $$$ and I keep saying that for a drop in kit YOUR RB would be better and performance difference is much of a muchness. like i previously said you be lucky to score a Sr20DET front cut for 4k than on top of that installation. so fuel economy cost more to install maybe better around the track. but for simplicity you cannot go past allready setup conversion of your RB.
