  1. Cool to see some more Ontario guys around here. jerryb, Thanks for the info, and the motor I was looking at is just a deal on a importer site. An RB25 with tranny harnesss etc is 1900 and a RB20 with the same parts is only 900, but a RB25 (engine only) is 900. So I was thinking if i could buy the RB20 with harness and trans and the RB25 motor I would have spent the same as I would for the RB25 swap but I'd have a extra RB20 laying around. But since the tranny and now that i have been looking around the harnees is probly diffrent as well, so that idea is out the window. Was worth a shot. You also have some honda buddies Careless?, how bad does the Z31 dominate them, haha My friend with the H22 accord weighs about the same as the Z31, its a tank, has power everything. He has done a little bit to it, just cams, a flywheel and an lsd so far. Who knows what he will have next summer when i get this thing together. Also I keep hearing a lot about how much these cars weigh, anyone really tried any serious weight reduction. I had a good look at the car lastnight but I havent tore into it or anything yet. I plan to put it on quite a diet and having the interior consist of nothing more than a cage, 2 buckets, a shifter, some pedals and a steering wheel.... actually the rules say i have to keep the dash to, but everything behind it will be gone. Car will see a lot more track than street use, would still like to keep it semi streetable tho for days i feel like testing it out or just driving it.
  2. I'm in Peterborough, about 2 hours from Toronto. Reason for asking was I came acrossed a RB20 for cheap and was thinking if anything off it would be worth while but i guess not. Are the tranny's the same for the RB20 and 25? Right now I'm just collecting parts and once I have just about everything I'll bring it all into my garage and start assembly (just wraping up another project in the next week or so first), for now the car is stored at a friends. I'm not looking for anything crazy power wise right out of the box, I'm planning on building the car for time attack and autocross, maybe the odd drift day. And of course to beat my friends Honda's at the strip, lol One has a Del sol with a B16 and the other has an older accord with an H22 swap. The RB25 already has more power than them both bone stock. An all out motor build is in the dream plans for another year tho, first I just want an RB powered Z to play around with, power will come later.
  3. I'm looking at putting an RB series engine into my Z31 and to save you from a long story just say I have a RB20 and RB25 sitting in my garage. I could just swap in the RB25 and be done with it. But I have heard of a RB24 using the RB25 block and head with the RB20 crank and rods. This combo would retain the 25 bore but shorten the stroke making the RB25 more rev happy which would be nice for keeping the turbo spooled and I dont think torque would fall off much if at all given the displacment dosent fall of much. My question tho is, is all that work worth it for just shortening the stroke? I'd only be changing the stroke from 71.7 to 69.7, that seems like such a minimal diffrence to me. But I'm not an expert on engine geometry so I'm looking for opinions. Also a bonus for this frankenstien is that its something diffrent. I'm not sure what would be done about pistons tho but 86mm is a popular size in GM land and comes in several diffrent cc's and pin heights, also several forgred versions are available as well. More than likely I'll just end up throwing the RB25 in, but just for the sake of curiosity lets say I want to try this 2.4 thing. Edit, I've searched on this for a while now and everything I find is people using the RB20 block for some reason. I figure the hole purpose of the 24 would be to make the 25 more rev happy.
  4. Probly no traction being on street tires and fwd. I love how much of a sleeper that is tho edit: you beat me to it
  5. lol when I was into the J bodies I wanted to do the same thing, put a cavalier wagon body on an S10 frame and make a rwd cavy wagon to tow my turbo sunbird around. Dosent seem like such a good idea now, lol Anyways, heres an article you may find of interest http://japanesenostalgiccar.com/blog/2008/09/11/nissan-1400-sunny-truck-put-out-to-pasture/#more-3305 You could win a free truck, I think its a nissan tho
  6. Am I the only one who liked st. anger? Then again I'm young and never liked the old metallica so had nothing to compare it to, the new cd is awesome tho, maybe I should look into there older stuff.
  7. lol the RB alone is double that, assuming rb26 but even still a rb20 swap would run you more than double that in the end, and thats before you even get started or have a car to put it in.
  8. Just to clairify as I'm a little fuzzy on two things. If i use a Z32 trans with an RB bellhousing in a 240Z will I run into shifter troubles or will it all line up the same as if I was using a RB25 trans? I ask because one person said they would have to modify there shifter area if using the RB trans and another said the trannys were the same minus the bellhousings, so I'm confused. Also this is for all Z32 trannys, correct? I noticed someone specify JDM Z32 trans, so I was wondering if the USDM ones were the same or not.
  9. If you looking for a set of narrow lights, how about a set off a 90's cutlass like this one http://www.tbi.state.tn.us/Cid/AmberAlert/Cutlass%20Supreme.jpg or these on the cutlass supreme http://upload.wikimedia.org/wikipedia/commons/8/87/Oldsmobile_Cutlass_Supreme_convertible.jpg also I'm suprised nobody has mentioned this yet, some you you guys are using or sugesting using fog lights/ baja jeep style lights but the problem with that is they are single filament bulb so you dont have a high and low beam, just one or the other. You need a OEM light from something on the road that has a double filament bulb.
