thanks for the heads up on the plate, ( proengins)

well had a go at making a wedge, first attempt nearly lost my finger, with the grinder.

but got there in the end, god 2mm one side 10mm the other side then drill out the center to fit over the thread.

but all on now and straight, all gaps the same to water pump studs 4mm, so well chuffed.

you cant use any other engine mount dave, because as it is there's 2 parts of fook all clearance between the bottom of the diff and the cross member. i posted a pic in here somewhere showing how close it sits

so, rd28 engine mounts solve the bonnet clearance issue? or is there something else? ive tried reading it all but no definative answer.

if u are enquiring about an rb30 in a gtr, u need to use the same mounts. u can slot the mount holes but not recommended due to lack of clearance

lol i gain an extra 200kg (stagea) over a gtr but my bonnet shuts without an issue with covers on and twin turbo pipe on :D I'd still rather lose 200kg and need less power lol.

I have been thinking about running twin gtrs turbos now instead of -5s, i think they are -10s from memory? I remember someone on here runs them on a 30 setup and wondering what the drivability is like? i want around 500hp at wheels mark on 18-20psi. Im running a freshened bottom end but still stock rods and duratech cast pistons, so still around the 8:1 comp ratio. I dont care if the thing blows to bits i wanna see how long it will last :down: My head is stock 26 with no port work and stock cams at the moment which wont help either, but bolt in cams are always a future option.

Ive got GTRS's, i want to swap them for dash 5's in the next month or so.

What rear does your set have?

Drivability is pretty much perfect as Marko said. Only things id change are turbos and cams

ok cool. just gotta figure out how im going to fit my s372r borg warner turbo in there...

Harden up mate, iraqi sand dune nissan patrol racer style right out the bonnet level with the roofline :laugh:

Maybe someone get shed some light on my current set-up and the issues I am having...

Im running a built RB30 bottom end with standard 25 vct head. The old set-up was running a GT3082r (0.82r) with 6 boost and supporting mods and made 280rwkw @ 17psi. This is through a built 5speed auto, fully manualised with 4500rpm stall.

I then changed to a GT35R with the same mods. On 11psi, the car made 246rwkw @ 7100rpm. We then upped the boost to 18psi, however the car only went 260rwkw and stopped making power after 6000rpm (sharply).

Any ideas what this could be? A few people have mentioned valve float but I also dont know how to verify this.

What size rear housing on the 35R and what size exhaust? cat? sounds like a restriction..

.82r ... its the exact same housing as the older 30R but just machined out to fit the larger exhaust wheel. No cat, just a muffle towards the end of the system (being a 3" mandrel).

    • @robbo_rb180 I already have a NEO head on the shitbox 馃槑 Just needs beehive springs so I can rev it past the 8600 rpm limiter, then again pointless too, turbo is out of puff lol. Wen da gods let me win lotto eh?
    • Everyone I know with a90 supra at time attack aren't having issues with 3-5 fast laps so far and one is decent powered one too. Saw a k24 swapped 86 with a 8hp70 and big slicks and aero which had no drama's at QR and Manton Park. I've stuck a 25 row cooler in my setup with 8hp45/50 in the hopes of keeping the oil cool as I plan on some racing next year that 20-30min sessions. I've also geared my car so won't be using 7th and 8th gear too. @Dose Pipe Sutututu just needs to get that samsonas in already and have that tassie guy fit a head and rev it too 11ty thousand rpm. 
    • My embedded systems thoughts have me sitting with GTS on this. Variation between same phone hardware, should be small. However, the internal "intensity" or "volume" amount that say Google passes to the app, will be quite different, as the underlying hardware will be passing different levels for the same volume to the Google OS. Until the app creator has had each individual phone, and set benchmarks and calibrations for each, the amount of error can be quite huge.   It can even be observed by using different phones, recording the same noise, and then playing it back, they end up soon ding different. A big reason for it, is even the different types of mics used in phones have different responses, and different frequency ranges. Then you need to get into the DSP, and the variations in those, their sample rates which then effect their frequency range, and then the quality of the DSP, and what type of hardware conversion they do to for the ADC within the DSP. Oh, and let's not forget at the low level phones are designed to cutout loud sounds. It's one of the reasons they suck in really loud environments (eg concerts). The louder you yell, the more you'll get cutout too Note DSP is Digital Signal Processor ADC is the analogue to data converter. I don't have any real data on what the variation would truly be, however, chat GPT says in general, their output is typically between +/-2dB to +/-5dB of what you're really measuring. So realistically, anything from 4 to 10dB variation is possible even with the same devices.
    • 'sif the error will be that low!
