Sounds like your not really looking for help or advice cos you know all the answers so i will leave you to it. No prob, thanks for the heads-up. I am looking for help and advice, just can't handle incorrect info. Obviously you can't handle being called on giving incorrect info. The following is fro...

The smaller water passages in the head are to equalize the temperature & prevent steam build up, the larger holes are the main coolant flow, the sediment & crud will always accumulate in the smaller passages (That's just the way it is) creating hotspots & causing head gasket problems. T...

Ok. So I fished through the various .pdf manuals I have here, and found the respective tables for gearbox ratios. Then screen-dumped and combined into one image... see below. Hope it's of use... Ok, thanks. Does anyone know the difference for the auto? It would be a safe bet that they would be in t...

Hi Will. I hear what you're saying, and in essence, you're correct, however I would caution against fitting an F8B box up to an F5A... Yep... "not ideal" was my way of covering that. :) I actually find it quite strange that Suzuki (being a Jap company) did not have a definite ID tag (or s...

I should have a thread on these by the end of the week. Standard Suzuki on the left, "replacement" pulley on the right. You might be better having a custom machined up anyway to save changing other pulleys.

[quote="Brayden" 1. No I haven't ever encountered the problem you've described. Then again I've never tried testing the design of ACL head gaskets by putting a fist full of dirt in the radiator either. 2. Assuming you have the complete F5A and box the downgrade should not cause you any pro...

no one would ever know unless you told them. it bolts in perfect like it was meant to be in there and is safe, i dont see any problems But, that's the problem right there - you have to tell "them" that the engine has been changed. The data plate states "F5A" as engine type, fitt...

I always assumed mightyboys had come with the 800cc option. I guess cause there's so bloody many around and of all the posts I've ever read stating "just chuck in an F8B" I don't ever recall them being followed by "but you'll need engineering". . Yep, that's the problem with int...

OK, now I understand what you mean, ta. That would be good advice to give a first year apprentice - just to see if they would actually do it...

Alternatively, get a hobby knife and trim your gasket to suit your engine. (Practice on the old, crusty one, first) I'm not really sure what you are recommending there...??!?! Anyway, after a but more research, it seems the F5A is bad for blowing head gaskets. After reviewing the head gasket design...

Yeah, RMS can be very pedantic about their rules and regulations. I will call tech support and ask, but I can see the answer now - and it will not be favourable for the F8B.

Here's the thing: 1. I am by no means an expert on any Suzuki, especially a MB 2. I cannot find ANY info on the F8B being fitted to a MB 3. F5A to F8B exceeds 20% increase - therefore engineer report req'd 4. I am always willing to be proven wrong. Random comments on the 'net doesn't count though An...

What model Mighty Boy came out with an F8B...?

HI all, Have just bought my first Mighty Boy and thought I would join the forum. Have been doing a bit of reading to try and gain as much info as I can... My car: Automatic, fairly original - bought as a non-goer (suspected blown head gasket...). One the way back home with it on the trailer I manage...
