pretty cool that 235 RWHP is enouth to take out a 911 turbo, Viper and Z06 Vett. do you know what the weight is?

Cuong: have you put a different intake manifold on?

a RB26 would be cool but at the end of the day a RB20 with $1000 in mods will have the same hp as the standard RB26 and still cost $1000 less than the RB26 did to start with

Excellent - well done!

did a bit of reading on hybridz.com, couldn't understand what they were going on about with the z31 rb20det, I thought all z's from '84 onwards were v6's Z31 200ZR - 2L turbo (RB20DET) Jap only

I'm 1/2 way through an R33 RB25DET conversion, it fits under the bonnet, sits as far back as the L24 did and I don't see any potential problems with it. RB30ET SOHC, there a little inefficient, 3L producing about 210hp compared to the RB25 producing 250hp at the same psi but I suppose that is without an intercooler. it is possible to put a Nissan DOCH RB head on the Holden RB30 block and / or intercooler it, that should bring up the efficiency thus hp. They should all have the engine mount holes in the same place and should all fit under the bonnet. the RB26DETT and RB25DET are the better standard engines but they all should supply enough hp after increasing the psi and other little bits to satisfy. try to get the engine with the wiring loom on it will make the job easier.

need to know the year to make a good estimate, as much as I hate to say it, Honda is very good at getting hp out of their engines. if you win let us know, can't stand the thought of a "fuel efficient", "front wheel drive", "economical" granny's car that was never intended to be raced beating a thoroughbred car such as a Z.

mmmmm, a Z that moves, wish mine did.

Engine stat sites or engine conversion sites?

and this site has some good info: http://www.zhome.com/ look under "How To Modify Your Z Car For More Horsepower" http://www.zhome.com/rnt/R&T.htm#power

these people who stick the v8's or 4's (yuck) in z's must have some efect on the weight distribution of the z. AussieZ and anyone else who has done so, have you noticed a big difference in cornering, etc?

I think it is a 2L 4 cylinder turbo producing 230hp, it would be lighter than the L24 6 cylinder and it almost has 100hp more so it would fly (and sound crap)

D) is it a good idea to start the engine every so often or does this not matter?

What did you do for a radiator? custom built radiator? does the skyline one fit? did you get the z radiator core increased or just use the z one as it is? Thanks

good to see ingenuity but a tree of all things! I thought I was dodgy using the deck support rails. It worked though I guess so well done.

Stange, Australia that has just about every type of deadly animal there is and just accross the ditch the one only deadly thing in NZ lives on the Australian side on New Zealand

Correct me if I'm wrong: '75, '76 have built in surge tanks, they fit into the previous year Z's, any latter model Z's fuel tank will not fit.

I'm with Cuong Nguyen and DOCH on the RB26DETT. The hp range this engine can supply will meet anyone's needs on road or track (280hp - 1350hp) and the engine weight won't be that different to the original. Failing that I would go to an RB25DET which too could supply enouth hp for anybody's road use needs. In a 240z = lighter AWD would be cool, failing that a strong LSD of some sort would do. Lowered, hardened suspension Spend a few days at a race track and dyno working out the how much power is just right. as for body work, well, I'm sure someone will be displeased about this but:

I have the same problem, spent ages trying to get it right but couldn't. I rang the local z parts / restorer guy about it and before I finish saying my "door doesn't shut properly dispite my efforts" he said it's screwed (gave me the impression this problem is not uncommon). He ordered me a new door mechanisum, the links and new door handle (couldn't just order a door mechanisum) $350NZD ($170USD).

no objections, remember to put yourself as NZ this time

Maybe there is a imbalanced part that at 5500rpm it reaches resonance and causes an oscillation (have I got that around the right way?)

"SOUTHERN HEMISPHERE" is a bit too broard, at least give an option for New Zealand and Australia, there are a lot of us in this site

I think the 350z will be superior compared to 85% of the skylines - faster than the gtx, gts, gts25, gts4, gts-t and gts25-t it will be slower than the gtr, well at least in the initial take off. The gtr has a superior engine but it is also a 4wd so it will loose a lot of the hp to the wheels and this might have some effect on the higher speeds. R32 GTS-T 0-100 in 6.3 (1320kg) R33 GTS25-T (1993) 0-100 in 6.2 (1370kg) R32 GTR (1989) 0-100 in 4.7 (1480kg) R33 (1995) 0-100 in 5.3 (1530kg) R34 (1999) 0-100 in 5.2 (1540kg)

Turbo rebuilds cost a bit, not as much as a brand new turbo but more than a second hand one
