Right. Its been 2 hours! I've been going over my research on plug gaps and I'm still not entirely sure if 0.025 is that bad. I've not seen anyone, anywhere recommend 1mm yet, many 0.7-0.8mm, 0.022-0.035" depending on set up and even a few of those lower ones don't have the original spark set up. I ...

Update: Byron has kindly examined it all and we have both decided that the problems really couldn't have been anything to do with his work. What impresses me is that Byron drove out, picked up the engine and spent quite sometime with me discussing the potential issues. Then he took it all away, stri...

Just gone back through your first post as well. Couple of things: - plug gaps - where has the 0.025" come from? 0.635mm seems a little tight, stock gap with the single coil and distributor in the way is ~0.8mm and reasonable gap for a coil on plug setup is around 1mm. The SAAB turbo lot gap these s...

Got the engine out today. Found the toughest to get to Bellhousing bolts weren't actually tightened so they came out easy. Loads of bits can be tidied properly once the engine is sorted. Loads is going into the parts washer to get ready for the install. Loads to do and there's never enough time eh.....

Hmm. Slightly out of my knowledge.

I will try and get some answers

Looks like the fuel pressure regulator is a Bosch 02801690263, 3.5bar The injectors are also Bosch, 42lb 440cc part number 0208150558, from a mustang or something like that... The rev limit was set to 7k which would probably put the injectors around 85% all reading and behaving correctly? I've yet t...

So having higher fuel pressure using a fixed pressure regulator and keeping the same injectors may improve any potential overworking on the top end but could further hinder the idle/off idle.. I see the advantage of 12 injectors. It must be easier to get the tuning right without having to do this? N...

This is/was kingcruzers right? I am only about 15 miles south of you, there are a couple of places that could take this on but it all depends what you are looking for in terms of cost. Looking at those pistons it looks like there may be a couple of factors in it, they do look very thin between the ...

I built some bits of the engine, I am more than happy to offer some help and advice to you.

Great, thanks

Detonation caused by a whole host of the above issues I guess.

What about the one crack/chip that looks as though its been pulled upwards? Could that be the ring knocking the hell out of the landing? It looks as though its been yanked rather than blown..

Hello all. I'm new on this forum so hello from me. I'm a heating engineer/plumber from Bristol and I love cars. I have just got an old flame back in my life... the e30. I bought my car a few months ago from an enthusiast with a supercharged m20 in it. I have been experiencing some engine issues and ...

My federals cracked on my M3. What the company is saying is a load of bollox I've used virtually every track tyre out there and I love the 595 compound and tread depth but the build quality must be the worst and the bollox I'm fed from the company I bought them from is embarrassing. Not good enough ...

I have an e30 with a 2.9 stroked m20. Forged pistons, new rods 5000K miles since build. Its 440 hp and will be a track car with occasional road use. It will get driven. Its full of 5w 30 which seems to be too thin. There is oil mist in a few places and although I'm installing some vacuum kit to help...
