Keep it simple and stop buying and trying sh1t that is only going to keep it and you off the road longer. Std CAS..Pay someone very vredible to do the rings on your pistons and rhen volt it together

Rings are easy! You just need a good eye and decent tools. You will need the following: - A ring grinder (I used a dremel rock on a cordless at low speed, balls) - A high quality feeler gauge - A n

If you have been in an RB26 with 2530s then you will realise with more compression, displacement and mutli throttles they are still not that responsive or really go anywhere under 4,500rpm. Maybes its the weight of the car that doesnt help either. But when they are on they are good things.

I suppose to your advantage is the fact that you have the same stroke as the RB26, only you are down a few ccs. I expect it to not really be hitting 18-20psi before 4,800rpm or so....at best....but will be interesting to see how it goes. Seems that this E85 stuff is a pretty good band-aid these days

As for the missing ingredient that coul deven help the response of your setup...well I am not telling, as what will my RB24 have over yours :down:

How do you work that out Rolls?

Well on an rb20 a single 2530 is laggy and on an rb25 it comes on full song about 4k which is pretty decent but with the shorter stroke you are running and the fact you have two of them! Even on an rb26 two of them is laggy!

Well, hurry up and get this bad boy finished :down: I can only guess what the setup will be like.....but I can be sure there is no way it will be in and making meaningful boost, enough for 200rwkws at 4,000rpm. What are 2530s., 320HP? So you have about 650hp of turbo to get spinning. Think a single 2530 on an RB20, then on a CA18....you are trying to spool one up with a CA12 minus one cylinder.

So not saying done do it, there is merit for going wins when chasing 350rwkws. Only be sure your expectations are realistic so not to be disappointed

...and my mates R33 had a 2530 on an RB25. No way it waited until 4,00rpm to come on. The thing was too responsive as it was always lighting up tyres. Best street car-230rwks going i think!

      r34's love to squeal

      By Nizzy_R34 · Posted

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
