Birth Of An Rb25

[BezerkR32]

the plenums are very well made, just need a little refining.

i like to retain the metal gasket with the rubber orings. this gasket only came out in series 1s, and you cant get them any more. they hold their shape and seal well. the all rubber gasket moves and gets squeazed out the side. have removed these seals when the metal one was not available and just used a paper gasket with sealer also. this works, but have to discard the studs supplied also.

Too bad about the Plazmaman plenum Stuart, I made a thicker gasket for my plenum (I think it mentioned that in the instructions that came with it?)

Looks like the build is going on very nicely though.

Keep up the good work and look fwd to see how it goes on the black stuff.

I picked up the correct throttle body from Plazmaman last night after Compak Attak and saw that their new plenums have a revised throttle mounting setup that allows enough room for the retaining nuts on either side. They also allow room for the fitting at the back that runs to the brake booster.

[BezerkR32]

if you had of put both his balls in your mouth at the same time he might have given you the better one.......

A bit unprofesional to sell the plenum knowing that there was issues with it, unless it was cheeeeeeep.

Nevertheless, plenum is sorted, sump is also well underway so our work will be done very soon......hope to be finished this week.

sorry, i have broken the one beer rule again..

I said retaining nuts, not balls!

Don't be sorry stu. You deserve a few beers after what 'drain has put you through on this build!

[2rismo]

Sump has been re-modified and Stu just sent me this pic from the workshop of the first part of the oil supply all plumbed up.

[BezerkR32]

engine assy is in and bolted up. Nothing major to modify, just have to relocate a few minor things, and mount some of the new additions but otherwise all good. Aftermarket balancer is incorrect however and will need to be replaced.

Shoud complete the majority of these things today with exception to the balancer. Thermo fan & shroud will also require fitting as engine fan and factory shtoud no-longer fit.

[JAS-25T]

wow. just about done!

well the engine building part is!

Hello dear, and welcome back to 'the bay'.

[BOZ22N]

very nice, love the plenum.

[2rismo]

the brains trust going for it

If more people knew the grief involved before they started there would by way less modified cars out there. Its been almost 12 months of modifing the modifications, hacking, cutting changing, discarding, reaarranging components to get it all to work as a unit. I thought I did my homework but there are so many hidden perils just waiting to bite you on the arse.

The next person that tries to sell me a part and insists it simply "bolts straight on" will have said part rammed up their coit.

THERE IS NO SUCH THING AS A BOLT ON MOD?

Good luck with this build 2rismo and i hope your pain is way less than mine has been. There are quite a few up here keen to see your car run at jambo.

Every single part (or most) on our car has been Jap off the shelf stuff...why?...not because im rich...its because it fits and works everytime.

To Alex's defence...he once sold me a plenum that wasn't right...so the next day drove 6 hrs (3 hrs each way) to fix it.

Because it's an RB26.

The backup from the guys at Plazmaman has been great and they've been proactive about quizzing me on what should be improved.

Hello dear, and welcome back to 'the bay'.

Man my turbo is going to look tiny as a highmount compared to that.Maybe a GT3082 is on the cards

[BezerkR32]

the driveability of the 30/40 is excellent, have fitted this turbo to half a dozen r33s, two auto, the majority of these with standard internalls. adrians with the bigger exhaust housing due to the engine mods and use of gas. you be silly to upgrade to anything smaller. I would seriously consider gt42 if it is a auto race car.

all-so finished the pressure side of the oil system, ran hose around radiator and through inline filter on driver-side chassis rail. there is a good 2 meters of -12 hose which eliminates the need for an oil cooler. mounted filter in a bosch fuel pump bracket.

my work is almost done.

I opted for the GT3076 .82 as the car will be used mostly for club sprints and motokhana type stuff. Anything bigger and lag would be so annoying in the really tight and twisty sections.

Good to see that motor in though, im dying to get mine in and running.

[2rismo]

The oil filter can be seen here neatly mounted to the front of the rail. Damn it looks good in there now! Much better than an empty space.

[BezerkR32]

definately the right choice for your application...

go on...do it...i have a friend with one for sale...ceramic coated and only done 4 passes.

[2rismo]

Going to run the GT35 hard and then swap for something bigger. Either a 42 or a 51R. That is provided it the 35R won't do what I want. If it does, then there will be no need to change it.
