The new gearbox jumps out of 3rd, its useless!
I dropped out the gear oil and put new oil in. I also made a new much lighter gear knob.
Alas it still pops out of gearI might go scrappy and get another gearbox
:doh: bent fork you reckon kev ? would a stronger indent spring help maybe ?
Sounds like a challenge
I have stripped, checked and rebuilt 3 Ford boxes at uni. Rwd type 9 box, which was relatively easy. Fwd escort box, which was terrible and I hated it and then formula Ford quick change hewland box, quick and easy that one
But all boxes had been steam cleaned and were mint
I think indent springs hold the syncros in or a ball and spring on selector shaft i think

Adjustable fuel regulator is a different fitment! My options are too make a take off to replace the stock reg or mod the rail. Or get a new regulator.
However, I have just discovered that you can crush or dimple the stock regulator for more pressure. I just need a pressure gauge so that I dont go too far. It works on most regulators!
Ill report back once I have results

you just remove the smaller O ring inside your reg kev, and fuel flows straight through it (then into the adjustable one eh)
Sweet nice one Frank (Y) tbh Iam still gonna try crushing it too see what happens!
How much do you want for the crank sensor setup? Might fit my megasquirt

postage to you dude
Ok so the last few days I have put serious thought into boosting my micra. This is all thanks to the dad I never had mr. Frank haha
Well I will see how frank gets on in the near future!
But Iam getting close to swapping pistons and things about for hi compression.
I cannot decide whether to go Hi comp now and stay na then build a low comp cg10 in the future.
Or get the head off, open out the chambers too lower the comp then slap it back together with cams, turbo and megasquirt (or stock management modded)
Help me decide
Parts I have:
Megasquirt
Td04
Pulsar ic
spare cg13

cheers, and i think the jury is out on the oilfeed tap-off kev, and it flies out the pipe but flows very slow through the tub (it has absolutely zero shaft play btw)
and try a google search on "high compression low boost" i think the honda boys have been doing it for years (no lag/efficient offboost cruising etc )

Tbh Frank it probably would fly out of the turbo if the drain had a small bore like the feed, I imagine the bearing is a huge restriction
Hi comp as in 10:1? Or 12:1? a lot of guys on swift gti forums push 10psi on stock engines, a lot of the parts I have are from my swift gti engined mini that I was planning on boosting

i,m thinking 11:1 max kev, i guess its the limit of pumpfuel.
mine,s probably gonna have 125hp at best, but i,m hoping for a big gain in midrange grunt
SR20-esque (with CG handling)Personally I think 11:1 is pushing your luck on pump fuel and no remap
And no intercooler
Madness
Iam aiming for stock compression setup with either front mount ic or maybe use the pace charge cooler kit I have. I got the charge cooler kit for 100 off of eBay but its missing the rad and resevoir, I got for a mk2 fiesta zetec I had, was gonna get boosted lol
I need to try and find my megasquirt

I started some headwork.
Stock port
Started to remove casting marks
Some of the porting and knife edging the devider
The blend from seat to port throat, I've done a lot of work here to remove the steps and crapness
Some more of partially worked ports
Also started to polish the chambers and smooth in the seats. Can't do much deshrouding as head gasket is too close
At the bottom of the seat there is a ditch in the port. It'll hurt flow and i don't know where to start nodding to help it. Filling and resgaping would be good. Poor design and poor machining! Thanks nissan

Some of the lobes have pretty bad damage on Kent cams
sorry for bad pic! They are useable but not ideal and they were also mega cheap
I measured each lobe so that I can machine the cga3 valves too suit my cams. iam hoping they won't need to much alterations with shims
A butterfly just landed next to me whilst writing this post
At lunch today I found some parts in my store shed
Pace chargecooler kit for a cossie.
Bag of hoses, wiring and pumps ect for cooler. Just need rad and resevoir!
Td04l from a wrx, these rock on starlets and swifts and i have more than 2 lol
And I managed to find my megasquirt, which reminds me I need to pm Frank. Exciting shizzle!

Last Wednesday my grandad passed away I used to see him everyday when i went the workshop ect.
Up until 4/5 months ago he was competing in ploughing competitions. his funeral is on Thursday and we decided to tow hime behind his favourite tractor, a super dexta! Here is a pic of the trailer.

More clutch stuff
Originally my double diaphragm clutch didn't work because i machined back the drive plate to offset the extra spring
In the pic below you can see that the rivet touches down on the flywheel just as pressure is applied.
I fixed it by replacing the drive plate and maching the extra off of the otherside of plate.
Now ill be able to use my Frank spec clutch plate.

Now some more cylinder head stuff.
In the pic Iam pointing at the ditch/step. Iam gonna try smooth it out with epoxy resin or epoxy stainless steel.
This is standard untouched
This is my smoothing work on the bottom of the port/throat. Pretty good shape and smoothnicity
And this is standard untouched
Made a start on exhaust manifold flanges, it shouldn't take me long too get the manifold and turbo bolted on. Then I need to see about an oil feed pipe. Iam gonna get a long pipe made to reach from the oil pressure switch on the back of the block, around the front too the turbo!
I need to remove and mod the sump for oil return!
Hopefully I will have a new gearbox tonight, just waiting for scrappy to remove one for me, might get another spare asap but serious tempted to go for a cg13 box now!
Also decided on colour and finish for my wheels but gotta enquire first

I am sorry for you and your family, but the idea with his favourite tractor ist really nice!Last Wednesday my grandad passed away

Tried testing the ports and valves at full lift, I tried using ciggy smoke! Pretty rubbish test tbh I need to just fit it and dyno it!

If you haven't changed anything else other than the head work and get it up on the same rollers you used last time, it will be very interesting to see what happens, especially since no-one has done a direct comparison to date.
It wont be a completely solid comparison mind due to the car bot being fully optimized completely on either setup but as a straight bolt with some fuel pressure fiddling it will be interesting for people considering the DIY approach.
Looking forward to seeing the results

Yeah dude I use the same rollers every time.
However Iam fitting head and cams at the same time so won't be ideal but still good to know what difference they make!
The plan is as follows.
Finish + fit new engine
Test new engine
Fit megasquirt
Test megasquirt
Then turbo once megasquirt ect is pukka
Iam going for as much power as possible with megasquirt, td04 and stock engine! Maybe 140-150hp being sensible
