i just got a fairly bare r32 rb26 with just the block, head, harmonic balancer, intake and exhaust manifolds no electrics left on it and its been sitting a while and dunno how manny k's its done so its gonna need a rebuild but i've already got a rb20 in my silvia is there any way i could rebuild the rb26 and still use the rb20 wiring harness and electrics, i got a heltec E8 ecu setup for the rb20 and i guess that can be adjusted for the extra displacement , any help would be appreciated

ok so i got the engine rebuilt and putting it all together now so is it possible to get this 26 running with my 20 harness and programed haltec ecu

help me out lads i think it will work i just need some backup :yes:

the only problem i can see is the TPS depending on what you are going to use for an inlet manifold

i was thinkin that too but i'm hopeing the sensor will be similar even if i have to cut and solder the wires to fit if not iwas thinking of buying a greddy plenum or similar and puttin a 90mm throtle body on it

      What could be causing my clutch problem besides a bad master or slave then? Both those parts are new

      Just came across this, but in QLD I start leave again in 2 weeks, if it is still available I might drive up and check it out Unless, @MBS206 do you live near here????, if so I could hit you up with a finders fee https://www.gumtree.com.au/s-ad/hope-island/auto-body-parts/nc-mx5-factory-hard-top/1328976391

      My hold point for future mods is that I want a OEM detachable hard top first, but, finding one is a pain, MX5 Mania are looking for one for me, but, as hens teeth are more common, finding one in Australia is proving problematic  I can get a OEM one from overseas, hell, you can still get new ones in 'Merica, but, shipping is a absolute killer and I cannot justify the cost, or the risk of it being damaged during transport As for the aftermarket hardtops, whilst they do the job of being a hard top, and are fine for a track car, they don't seal well (read: leak like a sieve in the rain), and you need a plastic/poly rear window, plus they are a bolt in option only and not made to be easily removed I liked how the hard top on my NB could be fitted, and removed, by myself, in less than 5 minutes I know it sounds bad, but I'm waiting for someone to write off a car with one so I can swoop in on their pain, it will go to a good home though, so my guilt of this is tempered

      No, you don't want to plug the vacuum line, as that will turn that side of the booster into an air spring and probably make it feel worse. I'm not saying that the GTR master itself doesn't need a booster. I haven't paid attention to the GTR one to know what size it is cf the non-GTR ones. But when you think about it - they have to do the same job, which is to move a little slave piston a few mm to do what it is supposed to do, and that final action is the same on all the cars. So, it is very unlikely that the GTR MC is any different than the others, because it has the same pedal stroke and the same output requirement. The booster just makes it feel easier. I'd suggest you probably have an actual hydraulic problem. It's totally common on these old shitboxes.
