You wanted something to do. So start building that 200 HP 1.4 and see what comes of it.

I'm afraid that what may come of it would be a pile of broken parts, and no new records.


That's true - I could get my hands on a 1.4L 3 cylinder.  That being said, I haven't seen many (if any) 1.4's over 200HP.


I'm actively soliciting ideas to build a 1.5L displacement (actually needs to be just under 1.5L) engine for a land speed racing application.

Ideas include having a crankshaft welded and ground to de-stroke a 1.9 down to 1.5.

Another idea might involve sleeving a block, or building a bad-ass 1.4L 3 cylinder.

Let's hear some ideas, please.

Is there anything to support the top of the gear/oil pump shaft from deflecting?


Diesel Swaps / "Franken" IDI into Opel Manta???
« on: August 21, 2017, 04:11:15 pm »
OK - I'm having visions of putting a 1.6 or 1.5 IDI turbo engine into an Opel Manta project that I will start work on very soon.

Thinkning of something like a T5 or Toyota 5speed for a transmission.

What are the common issues with doing an "inline" VW IDI swap?  Acme adapter plate for the trans?  Motor mounts would have to be fabbed.  Plumbing to the radiator and intercooler would have to be custom as well.

Help me brainstorm this project, please....

IDI Engine / Fabbing an intake manifold - design ideas?
« on: February 21, 2017, 12:02:55 pm »
OK team, I have been thinking of fabbing my own intake manifold for a turbodiesel application, and I'm soliciting design ideas and manufacturing techniques.

I've seen pics of several, but don't have a great grasp of the design criteria (runner length, plenum volume, tapered versus straight runners, etc).

Please help educate me.

Also, are there any suppliers for intake manifold flanges (like there are for header flanges)?  I've seen people cut OEM manifolds apart to use the flange, but not sure if I've seen any commercially available intake manifold flanges.


IDI Engine / Re: time to choose a turbo for the build!

Great looking build!  I agree that HE200WG is a great turbo for this type engine.  Is this going into a daily driver?


Yeah - I broke 2 engines this year - nobody to blame but myself.  I am making a promise to myself to go a little easier on the "tune ups" for 2017.  I'm tired of breaking stuff, buying new parts, and paying machine shop bills.

You are right, at Bonneville, the 1.5L record we hold is faster than both the 2 liter and the 3 liter record.

At Ohio, the 1.5L record we hold is faster than the 2 liter, 3 liter, and 4.25 ( G, F, and E).

I think there's a lot of room for improvement in all those classes, particularly as the DT classes become more popular with wider availability of small diesel engines.

Alcaid has had his problems this year, and Darrell Vitone has blown up a couple (I believe 2) air cooled engines running land speed events in California.

This is a good time of year to start setting specific goals for 2017 and start working towards them.


Sorry to hear that about your cylinder head, Alcaid.   This has not been a particularly good year in the VW world in terms of pushing HP limits and damaging engines.


IDI Engine / Re: polishing journal and connecting rod on a 1.5

Polishing the small end of the rod is generally not done unless new bushings need to be installed in the rods.

At that time, the bushings are honed to size.


IDI Engine / Re: Leaky injectors
« on: September 28, 2016, 05:18:28 pm »
Try to eliminate the most common source of leaks first - the rubber "loop lines" that run from injector to injector are the first place to check.

Liquid diesel fuel is almost certainly not leaking from the heat shield surface backwards and upwards out past the threads.

What has led you to believe that the rod bearings are bad in your 1.5?  Does the engine currently run?


IDI Engine / Re: What causes this excessive wear?
« on: September 20, 2016, 05:28:49 pm »
My 2 cents - it's worth the extra effort to remove the engine from the vehicle so you can do this work in a more controlled manner.  Am I reading your post correctly that you are trying to "slip" the bearings in between the crank and the block with the crankshaft still in place???


I can personally attest to what happens with too much fuel for a given amount boost.  It's not pretty.  I was running about 40 psi of boost from a single turbo, but still too much fuel when this happened.....
