Nissan R32 Gtr Rebuild

[monga]

Hi guys I recently purchased a r32 GTR at the start of the year which seemed to be looked after and in good condition checked out by various workshops over here in WA and your ordinary RAC checks producing just under 400rwhp.

Compression being 150psi across all 6 with 4,5 being slightly down around 145 and the leak down passing fine

Unfortunately aftering travelling 5000km barely giving it boot I spun a bigend bearing at the drags on my second run , I dont know why it happened and was shocked because I thought the engines where bullet proof if maintained, until viewing many threads on here regarding the ageing rb26dett, so instantly after hearing the KNOCK KNOCK KNOCK I got the truck and took her home in the garage leaving her to rest till now.

Well after saving its time for the rebuild and personally wouldnt know what sort of gear I should go with and would appreciate any sort of advice, it will be daily driven and barely abused avoiding drag and track racing. Sort of HP I am chasing is around 430rwhp on a safe tune with the possibility to reach 470rwhp with a more aggressive approach.

One thing im interested in is a Apexi D Jetro ECU and possible Arias pistons, both being reccommended from various people.

The current running gear on her is mild mods including HKS Turbos, exhuast, injectors, fuel pump, cams, clutch, flywheel and the stock ECU modified in Japan to suit the modifacations plus other stuff gear iv forgotten with the gear all maintained and in good working order.

Latest Dyno

All advice would be appreciated guys,

Thanks

I had my RB26 rebuild 3 years ago using standard crank with ACL race bearings, standard conrods shotpeened and ARP2000 rod bolts, and Arias forged pistons. Car was making ~350kw at the wheels for this period, and it never missed a beat. Pulled the engine down and it was still in pretty good condition after the abuse it copped from my right foot.

As you are not after a heap of power I would reccomend the following;\

Standard crank with JUN oil pump collar (Proengines sell a JUN copy for a fraction of the price which does the job fine).

ACL race series bearings

Eagle conrods (cheap as chips at the moment)

Arias forged pistons

That bottom end will hold up for a long time with the power you are aiming for. Give the head a good service, do a bit of porting and polishing while you are at it and slap it back together with a decent headgasket.
