OK been mushing the gray matter up top and crunching some numbers around....... well SolidWorks has anyway. I seem to arrive at a weight figure closer to 1800kg plus a bit more for safety, so my first estimates were a little off the mark.... oooooppppsssss !!!!! A bit releived to say the least, but on the bright side the overall weight will be better to drive and handle, and also pwr/wgt ratio will be more acceptable.... thanks again for all your advice..... nige

Hi Guys, just wanted to say a huge thank you to you all for the information already given...... its amazing !!! The second part of this is obviousely gearbox selection, I've often wondered why we had two feet, and have come to the conclusion its to race auto !!!! I've seen some info about electronic controlled auto, is this for real? can you shift without taking your hands off the steering wheel????? again, any advice info etc etc will be so appreciated. best regards nige

Hey Bubba, nice idea, whats a VH41 out of?? scuse my ignorance !! If say I took everything out of a 4wd GTR as you say, and transplant the driveline, is it possible to do a 2wd variant?? I welded up the rear LSD in the back end of my scubie box, because it was s rear engined configuration with a reverse rotation transfer box, the front wheel drive wasn't needed, wouldn't work from the back of the car anyhow. This was done because taking drive from only the rear output shaft, the front diff would just spin and you wouldn't get any drive out the back.... Could this method also be done withan AWD nissan box?? just gives me options in choosing to go down the 4wd route and not 2wd......bigger choices.. I'm not the least bit worried about engineering things, I can design the frame around anything, thats why its termed "spaceframe" in my mind, just want to design into the car, the reliability, good power and torque and not too trick because of getting hold of replacement parts.. Engine size is somewhere about 3.4L 3.5L turbo'd of course, is this readily available?? cheers nige

Hiya, so from your excellent list, I could get a VG30DETT and auto box out of a 300zx, but this would be a "heavy" option or... VQ30DE out of a maxima but have to adapt the gearbox any idea of a ballpark weight figure for both engines??? rough guess is good enough for me...... thank you for your input, its fantastic.... nige

Ha ha nice one, give us a bit more to go on??????? VH41..v8 ?? wheres that come from? gearbox config?? yeah an Price ?????

Hi Nic, you are a star, VQ sounds pretty good, don't have too much experience in the boost area, my scubie was as standard as they come, if like you say they are lighter and tons more torque then my ears are perked..... I really require good torque low mid but not so much high I guess, need to be able to pull from corners rather than outright overall speed, in our sport its more won in the turns rather than the straights, but don't get me wrong, top speed is important too, its the whole packaqge that makes the difference on lap times. ah yes, lap times = 20km plus !!!!! I digress.... so what would a VQ30DE be out of?? need to search for donors etc etc thanks again

Guys, thank you so much for your info, its priceless, just what the doctor ordered.. rules on 4WD, urm i'm looking at 2wd Extreme as a class, cos there are no limits on design,except the body must substantially resemble a mass produced vehicle. I'm not completely set against 4wd, my last car in the uk was a scubie 2lt turbo and 5 spd box (modified), fully independent suspension front and rear, and permanent 4wd. scared the s**t out of me as it was 400kg lighter than the street version. But I'm looking at building something different this time..... theres so much up in the air, decisions decisions......

Hi Gazza750 What chassis or model would this be out of?? whats the cylinder capacity? There is a configuration which replaces the clutch with a torque converter, could this be done with a getrag box? at this stage I can only assume you change gear with a blip in throttle at the same time?? trying to find out more info on that.. thanks for your time anyhow, very much appreciated guys nige

Bubba, I was thinking auto as we only have two feet, I've raced both over the last 14 odd years, there are pluss's and minus's on both, but its governed more on the reliabilty side of things... OK whats an RB30DET out of?? please excuse my ignorance but whats a "Spool" and... (when they start getting sold to the public) you got my hopes up !!!! I take it they are not available?? thanks for your time nige

Hi guys, I postd this on the main skyline forum, but had a second thought that there may well be some top experts over here in WA, so be gentle I would like some expert opinion, if possible, to my problem. I'm designing a new off road racer, trophy truck, full spaceframe, independent front, 3 or 4 link rear axle, 20-26 inches of suspension travel, somewhere in the region of 2 - 2500kg all up weight, less if I can acheive it. I researched using a Skyline some 8 years ago back in the UK, but the rework on the gearbox for my design made it a non starter, now I'm out here, older and hopefully wiser and am investigating drivetrain options. The norm is 355 chevy and a TH400 auto box, but I'm not for following the crowd....... like to push the envelope somewhat. Yeah its painful sometimes but success brings so much satisfaction. Class rules limit engine size to 6L, so if theres a turbo in the equation I have to multiply engine size by 1.7 hence a 2.8 turbo * 1.7 = 4.76L overall. I have been advised already to possibly utilise an RB25..... but I am not up to spead with all the different configurations of engine/gearbox and differing chassis. I have been scouring this forum and many other websites, looking for answers, but having no experience in the nissan arena I thought it would be best to get into the open and put my problem forward. So if anyone has opinions, ideas, technical and any thoughts on the matter, i would be most appreciative. I've attached a naked photo and a fully dressed photo of two yank racers so you have an idea of where I'm designing. I thank you in advance...... Nige

Hi battery, the yanks build them like tanks because desert racing, baja mexico especially is the roughest terrain where the punishment on the frame and components is extreme. Their average size is some 2.2m wide, track width and 3m wheelbase, add on body work so that gives you an idea of their massiveness !!!!! I'm not building mine to that extent because I have to go around trees and follow narrower tracks that our smaller buggies have to fit around. Mine at the moment is 2m by 3m on the outside,of the bodywork. I design for power/weight ratio and go as light as possible but not compromising on cage safety or strength where its needed. I forgot to say on my first post that I'm restricted to 6L engine capacity, so something like a 2.8 turbo multiplied by 1.7 (turbo factor ) gives me a total capacity of 4.7L thereabouts...... but i'm looking for reliability, availability of spares, ease of maintenance and relatively cheap...... just looking for poeples ideas and opinions for a good strong engine/gearbox combo that might be able to handle what I do...... Loads of racers in the buggie classes run SR20's and they are virtually bullet proof........ Anything can be made to fit !!!!! cheers nige

Hi gang, just introducing myself onto this forum. i'm nige, over in perth,wa. new to the Nissan arena.. cheers.
