TOYOTA 7MG ENGINE

Oct 23rd, 2017

This 7MG engine is now complete.
To our customer, sorry to keep you waiting. The head cover is the strongest pink, just as requested.
It is the same shade of pink that our company logo uses.
We also have pink NAPREC T-shirts which were made last year, it’ll match nicely.

The parts for this very special engine have undergone WPC processing and have friction reduction.
The initial startup is important for high performance and a long lasting engine. Please ensure you put in the best engine oil possible and turn the oil really well before starting her up.
We’re excited to see it run!

Only thing left for us to do is pack it in a wooden box and send her off!

Welding type Oil pan

Oct 21st, 2017

Today we’re welding together an aluminum oil pan for a 6 cylinder engine.
The weld structure is processed using a sharpened block mounting flange and the back and surface are firmly welded.
It will not be annealed, but it is a very firm weld.

After this, we will finish the flange surface and the work is complete.

FERRARI308

Oct 07th, 2017

Today we’re tending to the wounds of a FERRARI 308 by weld repairing the cylinder head which has a crack in the combustion chamber.
We will perform checks, pre-welding treatment, then laser weld by melting with light and welding it as shown in the image.
Of course, after this we will perform a pressure check to confirm there are no leaks.

There have been many repairs similar to this as of late.
The engine that has had the most crack repairs is the Nissan S20.
We still have 6 head crack repairs to tend to after this.

FERRARI308燃焼室修理!

FERRARI308の燃焼室内にクラックのあるシリンダーヘッドを溶接修理しています。
溶接前チェックして、溶接前処理、その後に画像の様に光で溶かして溶接するレーザー溶接をします。
もちろん、この後は圧検を行い漏れの無いかのチェックをします。

最近この様な修理が多いですね。
一番多く亀裂修理するエンジンはダントツで日産S20です。
いまも6台程クラック修理のヘッドが来ています。

We’re working on a VR38 cylinder head today.
This time we’re going to do some CNC porting and processing the CNC combustion chamber.
The crank shaft has been rebalanced, and the valve seats will just get a cut, but we’re sure it’ll be a great finish.
I can never get tired of looking at these engines…

Lamborghini Diablo V12

Sep 23rd, 2017

We’re working on fixing up this guy today, the Lamborghini Diablo V12 cylinder head.
This engine had a cam line failure, and we’re going to be making new caps for it.
The image shows the engine about to undergo line boring. Since the diameter is small, we’re being extra careful with this one.
The thrust surface also looks banged up, so we’re going to fix up the end face as well.
We talked about cam caps in an oder blog, but they’re made through designing them in 3D-CAD and CADCAM, then cutting them out.
