that price is the bumper and shipping to columbus ohio less any taxes and extra fees. Almost worth taking a flight over there and bringing it back on the plane if you could. bumper by its self is aound 450 US tbs

got a reply from the company on the bumper cover "Thank you for your enquiry. Yes i can supply this part. I can only ship it as far as Colombus, Ohio. The cost to supply and ship this part will be NZD1600.00 [uSD1120.00]. This does not include US customs clearance, any taxes or surcharges, insurance or delivery. Regards, John Foxton." tbs

I've still have yet to hear back from that company. I'm thinking about calling them and ask them for a price to the States. tbs

could somebody please shoot me some measurements off of a maxima rotor? offset, diameter, thickness. tbs

why is it that s30s can make use of a rear vented rotor with some mods and the s130s don't have jack crap unless you want to buy a $1000+ kit. If my winter project list wasn't so big already I would try to figure something out. tbs

I truly believe for a engineer to be good he needs to step out side of his bubble and listen to what others have to say and not think that a piece of paper makes him god. BTW sorry to thehelix112 my off topic post. But I do agree with Tony that proper turbo sizing is everything and to be honest who else here is close to Jeffps power with a L6???? Once again life experience Tony and Jeff have been doing this for a long time. tbs

I emailed them today with my picture from my first post to make sure that they make it and asked for a price with shipping to the US. So we will know soon. tbs

yes please take a picture of it I'm getting ready to do this after the new year. tbs

you know I asked myself the same question and then I bought a ford valve guide to measure how far on they went and then make a two piece shim to between the spring seat and the valve stem when installing them. I'll dig out my tool and measure it and let you know. tbs

any pics yet of what you did to your tail shaft helix112? I'm interstead in how you made that work. tbs

I found this picture and seen a few on some japanese s130s, would like to get one but I don't know who makes it. tbs

personally I like my extra power accessories, but I didn't like the A/C, Cruise, and all of my emissions. Hey since your trashing your cruise you sould do a cable conversion. I did and love it, you'll need to do some custom fab work on the pedle, on the hole in the fire wall, and need to get a 84 200sx throttle cable. tbs

I think you guys are looking at the extra webbing in the wrong light. Yah a solid block like 1 fast z pointed out on the N42 would be very strong, but how flexible would it be? With that extra strength in a solid part also comes brittleness. Yes I understand that it was an alloy block, but its not that the F54 block is stronger, its that for a turbo application Nissan designed it to flex to keep the cylinder from cracking. I still stand by that the F54 is a perfect block for a turbo engine because of the changing pressures that is seen inside the cylinders Atmosphere, boost, Atmosphere, boost, ... (You know repeated loading and reduced loading) but I would say that an N42 would be ideal for a N/A build because the pressure inside doesn't fluctuate nearly to the extent that a turbo would see. At least this is why I think Nissan would have change there design. tbs

I'm thinking about trying a set of stock turbo piston, 240 rods and crank for now and if I like it have a custom set of pistons made for it. I'm thinking maybe a 87mm and possible adding a few cc's on top of the piston in a off set dome shape, I guess more like a heart to match the chambers, to bring my compression up to the 8.5-8.8 range. This is of course is with the P90 head, because if I remember correctly, if I'm wrong someone please correct me, for and engine to be more volume metric efficiency you should go with a larger chamber but still have a higher level of compression, but a large chamber yields less compression hence my offset heart idea to keep the compression ideal for the turbo and maintain a large chamber. But then again this set up will change my bore stroke ratio and I'm just starting to gather info on that before I set any of my plans into stone. Thoughts guys?? tbs

Thanks to everyone that has contributed, butthis was going in the right direction but seams to be more of a stroker build debate. I agree that a short rod makes for less detonation but you must remember that a short rod as it excleerated away and towards doesn't do so well for full combustion but it makes great vacume but in the land of turbo who needs vacume to do the work. Stroking the L28 is a great idea but I don't see why to because you can't get the proper flow out of our heads to make the short stroke effective(with out lots of money and work) this isn't some 4 valve pent roof chambers its an old 2 valve heart shape. The more fuel I can burn in a tightly compressed area the more power that can be transmitted to the crank shaft, hench the increased dwell time at tdc of the longer rods. But then again the entire tune needs to be set up propperly because of the ignition timing needed for a long rod so trying to balance this with not detonating. I think the design needs to work around all the variables not just one or two. For N/A I would do a big stroker and be happy but time and time again the japaness with there small 2.0 turbo engine (4G63) make lots of power with a turbo. Finally the rb26 has a small stroke and a realively good r/s and it makes Most of the L6s look like a bunch of toys. I would say that they figured out what needs to be done to make power out of a inline 6 but that just my opinion. but thanks again for posting guys maybe if you concentrate on rod/stroke for a turbo we could be the sticky that DAW has been after. tbs

what generation of 240sx are you guys getting the gear boxs out of or would any box be a good choice? tbs

Ok I'm looking into a future build up for an turbo L6. First off I'm thinking about just staying with the L6 heads and forget about the 24 valve head but enough of that on with my subject. I understand that you can go long or short with the rod ratio and the effects and reasons to pick each of these but all my literature seemed to geared toward Naturally Aspirated motors with multiple head valves and didn’t explain too much if any on how it would effect a turbo motor.. I understand that a rod ratio is only one of many variables in building up great engine. Yes I've searched and found in the turbo section a long rod turbo L6 theory I fell that this subject should be discussed once again but how about some of you higher HP L6 guys show up and post (you know who you are). Ok guys, which would be better for a build, long or Short rod ratio? I'll get the ball rolling, I am now thinking of a long rod ratio something between 1.75:1 to 1.8:1 because of the increased dwell time that the piston stays at on TDC because of our older two valve heads. I don't know I could be wrong though so if I am please enlighten me. tbs

I have to thank Scottie-GNZ for mine set up. He told me that when he did his when his back when his Z had the L28et that he used an 84 200sx throttle cable. Its just a little long but now since I've got my custom intake manifold it is the perfect length. I had to modify the fire wall and the pedal some but it was worth it. tbs

One word "SEARCH". yes non turbo flat tops can be used but any repeat any detonation will break the ring lands. But then again I've just broke my turbo dished pistons with detonating under 20 lbs of boost. You can do it but don't except it to last too long. tbs

The tranny to use is out of a d50 truck thats how the starquests do it. and I've heard of a guy that had a bellhousing cast to use a 7mget transmissions. http://www.starquestclub.com tbs
