Looking for valve shims that are slightly thinner than the 2mm smallest offered by Toyota (I need about 1.8mm).

Any idea where these could be purchased?

You can get them directly from Toyota in various sizes - you can usually swap some of them around from other valves so you don't always need to get new ones. There is also an ROC 'bucket bank' if you know which ones you are after.

Edit - sorry missed it was a 2zz

OEM for the 2ZZ only go to 2mm

I've build an engine that should safely rev to 9500 rpm, but with reseating the valves and non OEM cams and valves, they are slightly out.

I can machine you some down if your struggling

I would be very interested in that. Thank you

Let me get exact spec of exactly what I need. I'm going offshore today though, so it won't be for a couple of weeks.

Might be worth looking at solid buckets instead then? My 1zz turbo cams needed a larger bucket than Toyota offered so in the end I went with an OEM cam as I didn't like the idea of a high revving engine having shims - the 1zz solid buckets are an upgrade for the 2JZ and 3S engines. I guess with the stock engine revving to 8,300 with shims the design must be ok to rev, would still be worried about a shim popping out though. Not having a 2zz I don't know if it uses a shim on bucket or a lash cap - you can easily get lash caps down to about 1mm - was looking at this option initially on my 1zz build - looks like they are 5.5mm so you can easily get smaller lash caps.

No problem, if you send me ones you have and what you need them to be i can carefully surface grind down to correct thickness for you :)

That's the bottom end built. About 100g lighter per rod and piston and happy to say they are within a gram of each other, so interesting to see what that does to the response. Everything barring the shims/cams have went in to spec, so very painless build so far.

Not going for power, but it's about giving the engine the best chance to cope with circuit racing whilst developing about OEM power.

Nice, that'll move through the rev range pretty swiftly.

Out of interest what power do you think it'll make if mapped for full chat, and how will you limit it, if required, to make the p/w ratio for SLS? What weight does the car come in at with the stripped interior, cage etc?

930kg with 1/3rd of a tank. 1030kg with me fully kitted.

Will rev limit it and retard the injection on the mapping.

Will make about 170-175bhp mapped for SLS class F.

Probably would do 190bhp at full beans, but its overbuilt for being able to take 20 lap sessions and maximise the mid range grunt (key for a series that is based on power to weight).

I would find it hard to compete with the cars in class E running at 195bhp, the class winners there are 1200kg cars running 260bhp-ish (turboed).

I'm 30bhp and a big chunk of mid-range torque short of being competitive going up a class, hence detune the car for class F.

Cool, thanks for the info.

I'm thinking about entering Class G this year. If you're 930kg stripped and caged, I reckon I'll be about 100kg more in roadgoing trim, semi-stripped, half cage, decent seat. Add me and it should easily slip under 130bhp/t as I assume it'll be down on the original 140bhp.

1ZZ will be class G, almost certainly, even stripped a bit.

If your doing G road going. 66-67s will be competitive times, which I recall you saying you were doing, so don't fear you're going to be 'slow'.

The Mini's dominate the G class, but they are all built Celticspeed Cooper Cup cars, driven by fairly handy drivers doing 63-62's.

SLS will be good this year, I'm probably going to be more Modsports focused but doing both

Bringing Modsports, Legends and SLS onto the same calendar will mean it's a relatively large meet. Initial indication is the grids are looking healthy.

Sounds great. This year will be a recce more than anything, finding my feet before deciding what to do in future.

Yeah, constant low 67s with a clear track, bone stock on Avon SV7s. A bit of work on the car, decent rubber and some tuition for me should hopefully bring that down a wee bit. I had a look at past lap times for each class, the Minis in G are quicker than some of the Clios in F! Quick wee things.

Depends on the cars and drivers. Nearly all the Minis are proper kitted cars and most have a driver that knows what they are doing driving them. I can't think of any of the Mini regulars who aren't fairly experienced drivers. Adam Kindness is probably the quickest in there just now, but he is experienced with the car, is a good driver and has done thousands and thousands of laps at Knockhill. With the Covid affected season last year, a lot of the mini guys came over to get laps, and some of them are driving proper race cars, and are at good amateur/semi pro level.

Some of the clios aren't so well set up and just regular track day drivers.

If you want any tips, I know the MR2 well around Knockhill. I'm not a pro or have any great experience by any means but I've a few podiums to my name and generally competitive when my car is working.

You're welcome to try out my car as well around the track (assuming you are 5'7 to 5'10), see how different it feels to OEM and maybe give development ideas.

Roj

Thanks for the offer, very generous. I'll give you a shout when I'm next heading to a track day. Not sure when that will be now tbh, as I've just bought a much bigger project (house), so car plans are up in the air until that's all worked out.

How's the engine build going?

AJRFulton

Cheers bud.

Build is going fine, now at point it's ready to mate top and bottom.

Biggest issue is I live in Aberdeen but my operation is based in Ayrshire - so only really getting a day at it per week.

Should be running by the end of the month

AJRFulton

Slowly getting there, working away from home 6 days from 7 isn't aiding this.

However that's valves set, and head on.

I'm in Aberdeen too. Can't help in the short term, but the place I'm moving to has a big outbuilding that I'll be converting to a garage/workshop. Once it's sorted you can have use of it in return for some help with my build :)

I technically live in Aberdeen, but still have all my kit in Ayrshire, in an out building at my parents small holding.

Biggest problem is I am fairly well kitted in Ayrshire, but to buy somewhere in Aberdeen where I could do this:

I mean, I'm a single man. So even to have a house with a garage, given Aberdeen prices,  the numbers do not make sense for me.

Roj

That's a decent set up you've got there, worth travelling back down the road for.

Aye, house prices up here aren't great. They've come down a bit lately but still a long way to go before they're sensible, given the number of job losses recently.

Where could I find the parts numbers for valve shims on the 2zzge? I do not know the exact size yet (likely 2.15 or 2.2mm)

I'm going to need to order one (after measuring) as I've 1 clearance level just out of spec (I doubt it would make any difference as it is marginal - but for the sake of a few quid.....)

it was a faff last time - trying to explain to the apprentice on the parts desk -  a part number would make this far far easier

Dunno how it is where you are, but £160k seems to be the bottom end of the market for anything with any sort of garage, and that's in a scheme.

Realistically anything in an area where you'd want to stay, with a usable sized garage, bottom end starts about £220k, probably over £250k for something you'd call half decent.

Issue for me is, even with a half decent job, being single, I'm a stretching the limit of what I can get mortgage wise to get onto the bottom end of the market up here.

I'd take the point in Ayrshire though. £200k would give you a lot of options in the middle market.

I live in Bromley SE London.
Studio flats start at over 100k.

I actually live right on the edge where it is cheap.
My neighbours just sold 4 beds over 3 floors no garage parking for 1 car 390k.
I'm lucky that my parents had money to lend otherwise I'd be paying 1200 a month for rent .

Where I was born in beckenham 3 bed houses start at 450k.
My first house was 1 bed I sold that for 275k.

Wages down south are usually better until you take house and rental prices into consideration.
I am pretty sure with all this working from home people will be moving further and further outside the m25. Unfortunately working in construction central London is where its at for me.

I know that doesn't help you in anyway it just makes me smile to hear what people pay around the UK for housing.
