| Post subject: | Redi strip and other small bore questions |
So i finally pulled the block off the box, got me thinkin... ive got a couple 1100 cranks here, is it worth the $600 to redi-strip it, bore it and chuck some 100 thou 1100 pistons and rings in? it is the original block (number matched to car) which is what i am a little apprehensive about... but hell.... why not right?

Go for it! There ain't no replacement for displacement... 1/2 the 998s out there seem to have a 1098 crank these days. It'll give you torque, something a Moke needs and a 998 lacks. But I'd make it +.080", then you have 1 rebore still up your sleeve. Or, if you want to save some $$$ use +.060" Hypatecs, they are cheap but good. That'll still give 1152cc. |

Get another block, they are (usually) cheap $20 to $50... mattsmadmini wrote: Tell me more about these Hypatecs....? For a very cheap piston they do take a hiding. I've had some very good success with these. Certainly in almost any 998 or 1100 you'd be very happy with them. Just be sure you get supplied the correct (Hastings) Rings. |

I get a set of hypertec pistons and hasting chrome rings thru auto pro here for around $210 complete. Try your local auto pro place and see what they come up with. If no good I will see what I can do. |

alright. Lindsay has them stocked and ready to go, 195 + 8.50 postage. Im going to bore out my original block (fairly confident with this choice) and slot them in (at least ill still have 2 more rebores if need be) Now, i have 2 1100 cranks... where can i take them to get looked over to determine which is the lesser of 2 evils? And can someone make comment on Redi-strip? have you used them? what is the actual process they use etc...? -matt |

Take both cranks up to Spiro, at St George Crankshafts, Bearing Rd, Seven Hills. 02 9674 1201 He regrinds all GR's cranks and knows what to look for.. re Redistrip, ask GR. They are good, but getting expensive... |

Last time I used redi strip they charged about $200 from memory to strip the block (Chemical dips ect) they do a great job but yep, getting expensive! |

Mix up some [molasses + water] mix in a plastic bin, drop the block in there for 3 or 4 weeks. Every week, take it out and hose it, then stick it back in. 
Note it works great on rust, but can't handle grease or oil. Degrease it first. |

... and don't put any of the alloy bits in, unless you want to get rid of them

Note it works great on rust, but can't handle grease or oil. Degrease it first. I've tried this with smaller parts, but never a block. I've had better success with vinegar though - one part vinegar to about six parts water. Everything comes out looking shiny and new - the only way you can tell it was ever rusted is the holes where the rust used to be. Having said this, I don't know how much it eats at the normal metal - I've used it on nuts and bolts and tuning pins for musical instruments without any hassle, but some of the surface must have been removed. |
