Ben's R32 Gtst Build

[Marlin]

I'd simply repair the head and slap a good piston and rod assy out of the other engine into it after a light hone. Unless it has actually damaged the bore to a point you need to bore it? If the latter I'd just junk it and start again.

Forgies aren't worth the expence, you're not near the limit of the stock gear yet.

[sav man]

I'm waiting for almighty benson to let me know which way i have to go

[PHaT MR30]

I just spoke to him, He said a 20b PP would be fine.. He can do a good deal on apex seals

[Marlin]

And you can V-mount everything too. The RX8 gets to, so everyone else can now too.

I'm keeping a close eye out for an ex-Super GT300 chassis. Should pass easily.

[sav man]

As long as it's a mazda i think you'll be fine. Seems the RX8 isn't getting any more reliable though

[Roy]

Any pics or info on how the oil pump gears went in? Pressure differences ?

[sav man]

I can take some. It was pretty easy, on the back of the pump there is 6-10 big phillips head screws. use an impact driver to get them off, cover lifts off, gears slip out easy, put some vasoline on the new ones and slip them in. Loctite, and impact driver the cover back on.

he pressure was 110psi, as it was just running a normal N1 releaf spring. I will enlarge the oil restricers, and drop the pressure back to 65-75psi with the new engine.

been a while, but the engine is back from the machine shop!!

[sav man]

started putting the engine back together today. Factory Nissan rings are great, none of them needed regapping.

[BOZ22N]

So what pistons and rods did you use?

[sav man]

standard RB20. It's just a stock RB20 with a nose on the crank, and ACL bearings

[BOZ22N]

What brand of pistons cause I thought the genuine ones were very pricy.

Are you still going with the hi comp set up?

[sav man]

I just used my DET pistons from my original engine.

[Roy]

So did you work out why the Nismo engine let go?

[sav man]

Wrong heat range plugs, tip fell off and went through the engine. But after I pulled it down, it was apparent it was a time bomb. The machinest didn't seat the valves properly, and some were leaking, and the Bearings were very warn. Looks like it was a very high km engine

[sav man]

more than likely a high km taxi engine, taking people to and from strip clubs

[Roy]

If I knew it was heading to the strip club I would have jumped in.

So is this going to be another E85 missile or more a 98 build? Good to see you were able to save the alloy RB20 race block!

[sav man]

e85 all the way. Yep I got some of that good VHT alloy in a can, it's now super light. Why people paint their blocks black is beond me, it's 1000x easier to work on a light engine, cause you can see what your doing.

[tweety bird]

what a epic build thread.

there's alot of info that i will take in.
