Hi guys

Just had a phone call about my r32 gtr and it's not good news

it has come back no good on the leak down test and I've been told the rings are passing oil which explains the smoke anyway Im just woundering wat the bottom end rebuild will invole part wise and cost wise ?????

Also wanna know if their is anything esle that I should do to the engine while in the state of no play e.g replace anything important while I'm their ?? Some told me to rebuild the whole engine but as we all know money don't grow in trees

Also compression test wasn't to bad at all

please help me out guys

Cheers

You have a few options and it depends where you want to take the car power wise.

1. look for a low genuine km half cut and do an engine transplant, swap any goodies/better parts over and sell the rest. - make sure this is tested by an independent company as a condition of purchase - you'll have to pay for the test.

A good half cut can be had for $10-11k, and there are a lot of parts you can sell and recover a reasonable amount of $ from. You'll probably get a few extras like boost controller, turbo timer, cams, turbos perhaps, but I'd be looking for something thats had no mods done at all, or very few.

I got a 94 GTR half cut for $11k from a guy called Ken James. I had STZ in Brisbane test it and it came up great. Cost about $500 to ship to Perth by road. I got the entire car as far as mechanicals go all the way to the rear wheel hubs. Only thing that was missing from the car was bodywork from the gearbox's rear yoke rearwards, doors windscreen, roof and seats. I ended up using most of the stuff inc the rear cradle, diff, wheel hubs gearbox, etc as it was better than mine. It also had a few extras like some atmo BOVs, ecu, and some other bits and pieces. :)

You can do most of the work with stripping and preparing the bits from the half cut yourself if you've got say a double *garage* to do the work in and an engine crane. Then you're just up for about $500-1000 in labour for an engine swap.

2. Rebuild

2a. Bare minimum build - just fix whats wrong. If its only rings, it'll be cheap, but also do bearings - they are cheap. Your engine builder can advise

2b. Better build - As suggested already, forged pistons etc. Limited only by your budget. Go speak to a reputable engine builder, outline your budget.

Go somewhere reputable for any work you do - kinda goes without saying really. This generally means some where that does this day in day out and is familiar with high performance turbo engines, preferably the RB26.

Good luck... its not as dim a situation as it may seem. Save some $ and do it right if you can afford the time.

      Have you not seen geospy.ai? It can now give GPS co ords to within a metre from a photo, even if it's a random photo you take inside. Supposedly at the moment only the government/law enforcement has access to that... Supposedly...

      I've got the rear ones, they're certainly beefy. I need to take them to my driveshaft guru to check over, he's very fussy about the quality of components so I'll let you know if they are made of cheese by a blind man.   Are you in Australia? A mate just had a set of EN26 shafts made for his K20 Lotus by our fabricator which were quite cheap (compared to Driveshaft Shop) so if you can procure the CV's and draw what you need he'd make them for ~$800 for the pair.

      Had I known the diff between R32 and R33 suspension I would have R33 suspension. That ship has sailed so I'm doing my best to replicate a drop spindle without spending $4k on a Billet one.

      OEM suspension starts to bind as soon as the car gets away from stock height. I locked in the caster and camber before cutting off the kingpin. I then let the upright down in a natural (unbound) state before re-attaching it. Now it moves freely in bump and droop relative to the new ride height. My plan is to add GKTech arms before the car is finished so I can dial camber and caster further. It will be fine. This isn't rocket science. Caster looks good, camber is good, upper arm doesn't cause crazy gain and it is now closer to the stock angle and bump steer checks out. Send it.

      Pay careful attention to the kinematics of that upper arm. The bloody things don't work properly even on a normal stock height R32. Nissan really screwed the pooch on that one. The fixes have included changing the hole locations on the bracket to change the angle of the inner pivot (which was fairly successful but usually makes it impossible to install or remove the arm without unbolting the bracket from the tower, which sucks) and various swivelling upper arm designs. ALL the swivelling upper arm designs that look like a capital I (with serifs) suck. All of them. Some of them are in fact terribly unsafe. Even the best one of them (the old UAS design) shat itself in short order on my car. The only upper arm that works as advertised and is pretty safe is the GKTech one. But it is high maintenance on a street car. I'm guessing that a 600HP car as (stupidly, IMO) low as you are going is not going to be a regular driver. So the maintenance issues on suspension parts are probably not going to be a problem. But you really must make sure that however your fairly drastically modded suspension ends up, that the upper arms swing through an arc that wants to keep the inner and outer bolts parallel. If the outer end travels through an arc that makes that end's bolt want to skew away from parallel with the inner bolt, you will build up enormous binding and compressing forces in the bushes, chew them out and hate life. The suspension compliance can actually be dominated by the bush binding, not the spring rate! It may be the case that even something like the GKTech arm won't work if your suspension kinematics become too weird, courtesy of all the cut and shut going on. Although you at least say there's no binding now, so maybe you're OK. Seeing as you're in the build phase, you could consider using R33/4 type upper arms (either that actual arm, OEM or aftermarket) or any similar wishbone designed to suit your available space, so alleviate the silliness of the R32 design. Then you can locate your inner pivots to provide the correct kinematics (camber gain on compression, etc).
