JapShow 2010 Preparation
JapShow is on the 4th July 2010, and is creeping up fast. The GTR is not ready as it misfires above 1.5 bar of boost and when it gets hot it misfires at just over a bar.
After doing a lot of research I came up with a few different options:
Splitfire - Super Direct Ignition System
Splitfire Super Direct Ignition System are what I am currently running and just after a years use and less than a few thousand miles they have failed, I expect this is due to the high under-bonnet temperatures and more importantly my right foot which finds itself planted at most opportunities. I bought these from Demon Tweeks for just under £400, now it's nearly impossible to get hold of them in the UK. So after speaking to Charlie at Thor Racing today trying to get a set a decided that it was best to look at another option.
Okada Projects ignition coil packs
Okada Projects - now these do look the business and were used on the Do-Luck Toyota Supra, after exchanging emails with Akira from Okada Projects themselves and talking to their UK reseller EDO Performance
I found out that this kit would cost over £1100 + VAT. That is crazy prices! You could buy three sets of splitfires for the price of a single set of Okada Projects coilpacks. It really makes me wonder who comes up with these ridiculous pricing sometimes. It explains why not many people have heard of this company as they are overpriced, and don't end up on many people's cars.

The Sumo Power
R33 aka "Fuujin" is one of the best built R33's I've seen and unlike the boys from Abbey Motorsport they've always been friendly when I've talked to them at Santa Pod. In their spec list they list the "Do Luck Ignition Kit" which is actually coil over plug ignition coil packs from a company called T M Works
in Japan. After a week of contacting Sumo Power with various questions doing my research before purchase I put in an order today which should arrive on Monday.
On the Fuujin the coil packs are not located under the spark plug cover like typical RB26 GTR's after talking to Mark this is to keep them cool and it makes a lot of sense. It can get extremely hot under the centre spark plug cover especially on some high speed drag runs. Luckily I purchased a nice set of chrome coil pack brackets that typically sit in the engine which I will be using to place the coil packs in a similar position as to the Fuujin R33. I have to fabricate a bracket for them to sit correctly and I'll try and retain the spark plug cover as aesthetically the engine looks a lot better.
Once the system arrives I'll get the coil packs installed and it's back off to TDI's for further mapping and hopefully get the car back to 2 Bar of boost and 800WHP.
