I bought those coils over 10 year's ago. And i think they cost all eight approx 350€ ~ 300£. They are aprox twice vs vag coil bag 10 years ago.. Yes they are maybe overkill. But after that never had any issues of emission at MOT. HC is slightly over 200ppm without any adjustment. And have Kent M256 ...

This is my wildcat setup.
ACR heads with smallest possible valves. 1.87" and 1.53".
John Eales manifold modded to suit heads and 48mm Jenvey throttle bodies. Kent M256 cam.

Been running new wild cat heads over 1400km in this summer.. Still driving daily. Hope to get dyno near future..

Thanks to all. Inc ACR.

Might see new light on this project. We are doing co-operation with ACR.

Will update near future..

She's running. I add Bars Leak original to cooling system and 2x running cycle cold to hot will eliminate leak. It will leak approx no more than 1ml of coolant only when hits operating temperature ~82c. And allways stop after that. Now i flush the system and start again without leak. I hope there is...

Surprise.. its leaking coolant between head gasket. Look like those stupid threaded core or cast plug's at head surface is leaking. Only one. So have to take head off or add some coolant sement/sealant. Its small leak, but big eneught to make small pee to my garage floor.. I just don't get it. Why? ...

Heads has been welded and machined. And first start yestyrday. Took some time because bought Europian cheapest l322 4.2 SC Rangie.. Back to project. Have to adjust some fuel maps today or tomorrow. It wont idle over 500rpm because it is running lean mixture. No major fluid leaks yet.. :) But damn th...

Sorry.. it is M228.. my mistage.. My fried like a lot that cam.. Engine is in old Opel with zf4hp 2wd auto box.. Just spoke to him on phone and hi thinks if swap slightly more radical cam, like M238.

I just finished my friend 3.9 engine. Home ported std heads wirh std size valves. Bigger valves is waste of flow.
10.6cr.
Kent M226 camshaft
Ported intake with 45mm home made trumpets.
Home made 38mm exhaust manififolds.
Megasquirt 3x with wasted spark.

It will make 260hp/361Nm @ flywheel.

Go for 4.6 heads. Exhaust port is bigger near valve guide vs old style heads.. Also you get more compression ratio.. You can also port those 4.6 heads.

If you are using 41.5mm inlet. Throat should be +37mm. But std valve seat will limit it to approx +36mm. If you are replacing seats. Dont go over 43mm inlet valve, because bigger wont help. It will resist flow to mutch. New seat is way to go if you want more power. Maybe some 42-42.5mm valve and new...

My 418hp SD1 run 7 years old road tyres witch are like stones. 2.7s/60ft and 112mph 13.9s 1/4 mile. 6.4s to 0-82.5mph. It will weight with driver and full tank 1700kg. So 0-60mph would be under 5s. G-tech say 4.6s.. My 2800kg Range Rover sport 4.2SC make 0-71.2mph just in 6.4s. 1/4mile 15.3s and 92....

Head has been welded again. And now machined and new seat fitted.. + pressure tested. Better than new one. Seller try to compensate only 4x inlet valve seats. But thats nothing. And they wont eaven response when i send pick of valve seat hole problem.. quite poor.. Also if we compare OE heads. OE ca...

Also friend of mine has got...

Forgot to say. That we are finding best solution to repair those heads in Finland and also seller try to do his best. Process is still in progress. Thanks for seller also..
