Ecu is a microtech lt8 very old skool but the price was right.
Hooked it all up and it fired up straight away now the fun part of tuning it .it does sound fairly crisp straight of the bat after mucking around slightly via the hand held controller. Looking forward to some road testing

A quick vid of it running

Amazing build Jeff, glad to see you are a local, looking forward to meeting up for a cruise in the near future. Matt

Thanks matt. Once the weathers a bit better hope to get some use out if it. !!

Are you foing efi also on yours? I have had good results with the blow thru carb mainly on bigger engines.so was struggling to take the step and go efi. !! im glad to finally do the efi conversion and was alot easier than i thought . No looking back now! Haha

Hi Mate, any tips on building a home made turbo manifold?

Pretty much any design will work.
Doesn't have to be perfect lengths and bends.
That said
Just depends on how involved you want to get with it
A tubular design with nice flowing bends will be more efficient and looks alot nicer.

Main place to get it right is the transition into the turbo collector.

Steam pipe is probably the best material to use and its nice to work with and easy to weld and wont warp or sag with heat.
Some of the heap Chinese stainless manifolds look nice but a prone to cracking.

Just consider firewall clearance for dunp pipe. Clutch cable clearance and where the turbo drain back will run when you are designing it.

Other than that after you have it all tacked up . Be sure to use either a spare old head with the header flange bolted to it. This will help prevent the flange plate warping or if no spare head better option is to have it clamped nicely to thick steel bench or plate when welding. Although you can get it machined after welding to ensure a nice seal if you wish.

That is only a couple of basic points . Sing out if you think i can help out. Anymore!

Cheers

Perfect, thank you.
For oil feed and drain, where did you use?
I was thinking the oil feed/gauge connection hole on the passenger side of the motor, the putting a 'T' pieve below my pcv valve to avoid tapping into the sump.

As for oil feed perfect. As for drain i wouldn't recommend running the line all the way to the opposite of the block. It may work but very far from ideal.
The drain back is important on any turbo application it has to be able to gravity drain and size of drain needs to be alot bigger than the feed. If you cant get get rid of the oil it will push out through the seals in the turbo and we have a smokey running setup in no time.

The only exception being using a oil scavenge pump to pump the oil back to the sump or rocker cover. mainly only used on low mount turbo setups on some v8s or on a rear mount turbo its a must.

Hi any updates with your project? How's the tuning going?

haven't updated for a while.
The tuning has been going well. i have been doing all of the tuning via the hand controller . And using a wideband 02 to log and measure afrs. Very happy with how easy it is to make adjustments.
I got it running reasonably well and has been driven a couple of times.it feels alot better conpared to the carb setup.

Currently i have the head off it as the motor was built along time ago and didnt have hardened seats.have now done that and also changing the camshaft while im there ( higher lift cam). Just spending abit of time getting all the valve geometry right. Anyone who has played with these engines will realize that you just cant bolt a higher lift cam in without checking anything.

Will do final tuning on the dyno when its all back together

Nice one Jeff. So the 26661 just won't make the numbers?
Which cam are you using now? I've heard of the Wade turbo grind but couldn't find the specs online anywhere. Clive cams have all the Wade profiles. Do you know if the Wade is more aggressive than the Crow 26661?
 
Cheers

Awesome thanks for that. The Crow double valve springs are really good. Can even be used on mild motors because the spring rate is not too high.
