BC springs are good for 11mm of lift and fit in the stock spring seats. I've checked - https://www.club4ag.com/forums/viewtopic.php?t=15683&start=30#p104740 I don't run the engine past 8200 rpm do you think those springs would cope ok? (Re. the comment about 7MG quality in the post) Engine uses...

Fair point about spring rotation. l think the best way to approach this is to replace the valve springs with some that will allow 10.5mm lift and will fit with the original bottom retainer. lncidently Catcams suggest the removal of the bottom spring retainer for their springs. Any ideas for springs ...

I have a couple of modified smallport cylinder heads, one came on an engine fully assembled and working. Not knowing any details about the head l decided to fit the springs and cams to another head that l had professionally modified. When l went to fit the springs (unknown make but probably CatCams)...

If you want a blacktop that is pretty much what you expect to see.
If it came as a complete unit $1300 is cheap so would be worth rebuilding should you need to.

Brilliant!
Thanks for this and l'm happy the values l'm using are close to ideal.
I will use 3.64v - 100 kpa as shown.

The AEM ecu requires max and min voltages plus max and min pressures, it does not have a learning facility. I used a MAP enabled AE86 specific Freedom ecu to read the pressures and the AEM to show the voltages, the voltages are not affected by calibration changes. A Mityvac was used to obtain the va...

These are U.K AE86 MAP sensor values (unless anyone knows any different )
Min volts 0.87
Min kpa 21

Max volts 3.80
Max kpa 114

You will find some in Ireland
BUT
You will have to try hard to get them shipped.

What a great 'find' that diagram is for me! Takes a little thought to get your head around the timings but it is invaluable, thank you. Where's it from?? Thanks jondee86, can count on you to always deliver such great diagrams & pics, besides all them words! All of the 'regulars' on here are fan...

Indeed l am desperate not to halve the injector pulse for the reason you mention. Probably over the summer l will try to adapt a proper crank trigger wheel to my power steering pulley as this seems to be the best way forward. I know there a a few companies that make a RWD P/S crank trigger pulley bu...

What a great 'find' that diagram is for me! Takes a little thought to get your head around the timings but it is invaluable, thank you. I will check again but I'm fairly sure my loom is set to inject all four at once (we have already had this conversation..) but my engine from the factory has the fo...

Sorry l should have said, l'm using a programmable ecu with the stock loom so l'm just trying to replicate what the stock ecu does.
l have no desire to go sequential.

Does anyone know how often the stock ecu fires the injectors?
Ideally in engine degrees (over 720°) or distributor teeth.
My distributor has 24 ne teeth at 30° and 4 cam? teeth at
180°

what are the pros and cons of either?

Did we just go around in a great big loop, wasn't this the original question?

Just wondered if there is an issue with mixing synthetic with mineral oils (however small the quantity) for these applications?

Redline transformed the gear change in my T50 gearbox and l like Motul 90 PA for a TRD diff.

What happens if you very slowly increase the power through the problem rpm area?
It may or may not be an acceleration correction problem.

Sure it's a pita to remove/replace but that is only because Toyota do things right, the hidden stuff is done properly too.
I once navigated in a Peugeot 205gti and we had to retire as the dashboard literally fell off

If the distributor has a pin holding the gear on, remove the pin and rotate the gear 180° on the distributor shaft
Re-fit distributor as normal.
Use a new roll pin to secure the gear.

Really helpful advice for someone.

I might be up for swapping a set of these for your Kelfords..

I'd not expect those things to make too much difference. In a way it is the standard cam followers that cause the compromise as these effectively limit the cam lift potential, any perfomance cam then has to rely on long duration to get the job done, it is the long duration that can cause driveabilit...

Whilst l appreciate your post is about changing the cams it maybe possible to get closer to your requirements with careful tuning of camshafts and ecu. Having less overlap at TDC will help idle, retard inlet and advance exhaust cams to get less overlap. Cold and hot starts are all about ecu calibrat...

If l remember correctly engine oil temps are based on engine rpm.. makes sense.. You are using higher cruising rpm's due to your lower FD so you would expect higher temperatures. Maybe you could try to lower coolant temperature or ideally fit a larger oil cooler. Heat exchangers, oil/water are appar...

So l can't decide if l discovered something here. Timing decided to return to 0° btdc (effectively no signal to ecu) at cold start up. Because of the camshafts l unplugged the cold start injector. Once the csi was re-plugged ignition returned to normal. The 0°btdc seemed random but now, thinking abo...

Just a big shout out for these.
Expensive for a bleed screw but good value considering the engineering involved and the ease at which bleeding brakes becomes.

To be honest the only way l can see an issue with what they charged is if they didn't adhere reasonably closely to a written quote.
I don't know about the US but in the U.K there is a distinct legal difference between a quote and an estimate.

5k$ does sound a lot for that work.
I'm in the U.K where this type of specialist work maybe less expensive, not sure.
I quoted Pounds Sterling but the exchange rate wouldn't make up that difference even if you allowed a 25% error
in actual cost.

How much are they asking then?

No.
Total should be around £2k
