i got the below email from an old s12 customer of mine. he was asking into engine swaps and i suggested the rb or det. he then replied with this.

i will keep these items in my silvia folder, thanks.

i went down here: http://www.mikestewartperformanceengineering.20m.com/

he fiddled with the leads for the loom and the cylinder went, then he poked the injection plugs and it was the one at the front. they look very worn and split, he said it looks like the engines been taken apart alot and that's probably why they've worn. so he's going to repair them for me.

he said not to think about the RB20 or S13, the RB20 would be too heavy and the S13 engines big ends go and other problems come with them. he said the engine i have is bomb-proof and i should just get a supercharger instead of a turbo. i found this idea interesting, as i dont think the car needs anymore than 250/260bhp.

you should check out his datsun 260z - 340bhp monster.

he also has a one owner bluebird zx turbo hatch sitting there with a bit of rust. it has my engine there and its only been driven by his stepdad and he once put a bleed valve on it. he would be willing to sell it. im thinking about it for the engine, but i dont have alot of space.

thanks for your time!

Jeesus,why didn't I think to get a supercharger instead of my det.It would have made so much more sense.

The RB is not too heavy. I have done this with my person RB20. Yes it is heavier, but I had the SE/V6 model and it wasnt that much. I can give advice as to if one is to do this, what mods they should do at the minimum to ensure all is well. If you are worried about weight and such, I suggest CA18DET personally.

a little bit of knowledge is a dangerous thing eh? common web 'knowledge' DETs with 'chocolate' bearings, ironic as they are identical to those in the bluebird and the ET in his S12...

bet you love it when you get E-mithers like those eh Pukka? maybe you should ask this Mike Stewart fella how to prep a classic Lotus F1 car or Chevron B16? he sounds like hes an 'expert', bound to know everything....

I replied when the email arrived and said pretty much what you guys have also stated. S12s came with the v6 weighing far more. The RB engine actually isnt that heavy. And i mentioned Japsters det as an example of a high powered det that has had no bigend bearing issue.. Its poor servicing and old age that are a cause for det failure. These engines are 20 years old and people are trying to tune them with bolt on mods without rebuilding them.Ive never had bigend bearings go on any of my dets'

It depends on how you treat them and what oil you use as well.A couple of well placed baffle plates will completely remove oil surge from the engine.
The ca18det was never any good if run on crappy 10w40 either,Mobil 15w50 will make it last a lot longer.
Anyway,there is more Nissan knowledge your little toe than in that tools whole body.If your man wants a proper job done then he will give it to you and not to mr classic car with his sheepercharger,or sorry I meant supercharger.
