Sick, yo! :D

Seriously sounding good, mate. Is love to do a be conversion, not sure my wallet could extend that far and the other half wouldn't be impressed with me.

Apart from the control (Syvecs, Pectel, Motec ECU for dwb) going dwb TB is not as expensive as I first thought.

The TB is $400 and the pedal is around $100, harness for the pedal around $20.

Then it's just a mod on the intake manifold to fit the damn thing.

I'm doing the floor mount pedal box and that will set me back around $1000 once I have all the master cylinders and bias controlls, but the dbw pedal controller probably could be fitted to the standard pedal with a bit of fab.

The big cost is the ECU to control it though, i've been wanting to change to a (Cosworth) Pectel SQ6, but looking at the lack of UK tuners with experience on this I think i'll be going with the Syvecs S8 instead (which is essentialy the same ECU with a different GUI). Would love some Cozzy electronics though :)

Greddy Breather Tank - Earls Oil Cooler and other bits

Just a little update - Greddy Breather Tank and Early Oil Cooler

Ordered some AN fitting to mod this but when I got the breather tank it was way smaller than I thought and basically my -10AN weld stubs ain't gonna work... So some -6AN on order and also a change to -8AN for the bottom connection, the -4AN for the top port is the right size though (1 out of 4 is bad, haha).








Oil Cooler - using this rather than a sandwich plate with the thermostat included

It's not necessary to have the breather tank for a mild tuned car, but it won't hurt either.

The breather tank is there to help remove any air that's in the water system, any air in the water system reduces the surface area of water in contact with the radiator and also has a significantly lower heat capacity than water, meaning that the water flowing through the radiator isn't acheiving 'best case' cooling.

Additives like Red line 'Water Wetter' also help by reducing the surface tension of the cooling water to provide a greater surface area for the water flowing through the radiator to be cooled, more surface area of water in contract with the radiator surfaces provides the most efficient cooling of that water.

By using a breather tank you are venting this trapped air and therefore increasing the surface area of water in contact with the radiator surfaces and increasing the heat capacity of the fluid flowing through the radiator, i.e. increasing the cooling efficiency of the radiator.

This is more important in a track car where the cars on the limit for extended times, rather than fast road which isn't long duration or require maximum cooling performance.

New Disks/Pads and Quick Release

Small update again, only added a few parts recently.

Works Bell Rapfix II - Yoshioka Special Edition







To be connected to a Nardi Semi-Corn Suede Wheel :)

My mate who looks after my 15 has an EVO and bought off me the DBA4000/DS2500 kit i'd bought for mine to be used with my Brembo's, ultimately I will be going to a race spec brake set up, but for now I just want to get the Brembos on as the brakes on mine have a lot to be desired.

So I've bought a set of new DBA5000 T3 2Piece Disks and another set of Ferrodo DS2500.












That's it for now. Hope to send these home soon so they can get fitted...

Love the works bell snap off, totally jap! :) I am looking at a few different wheel and boss setups and that sounds nice, with the Nardi. (something I will be going with but not sure to snap off or not...)

It also has alot to do with reducing the risk of det as when you dont run a breather set up you can get a fair bit of oil vapour from crankcase blow-by on fairly tuned engines!

Theres a lot of mixed opinions but from what I can gather running the breather vta is better as it completley reduces the risk of oil in your inlet..yet running the breather back into the intake helps top end power and frees up a few bhp..also if you get a decent baffled catch tank it should only be clean air going back in anyway..

Oh yeh and buying all these lovely parts and not being able to fit them myself would kill me!!!! :D

Edit - Ignore me lol thought it was a catch tank you had got not a breather for the water system! Silly me..

woot! always wanted DBAs! nice.
Cheers... This is my second set now and I never did fit the first ones, lol. If I can get the bells off without damaging them i'm going to powder coat them red to match the Brembo's. :)

With so many parts non-JDM for this build, when I get the chance to have one, it's gotta be done. Wheel wise i'm still deciding between a Sparco Lap 5 and the Nardi. The Nardi is a bit more expensive but will likely go that route. IMHO you gotta go quick release :)

LOL.... I should be ok on the det side, just bought a KS-4 wideband knock sensor (SXOC group buy) and i'll be running VP MS109 unleaded race fuel which has high det protection even at high CRs and boost pressures, so should be ok on that side of things, the 105 octane won't hurt either :)

About the oil catch can, I originaly bought a Cusco can but I didn't fit it in the end (still got it), I will be running a crank case breather to a custom box with a couple of mini K&N filters on it in pretty much the same location as the ABS unit (which will be gone), it will run vta and it won't be recirc'd back into the inlet, I don't think i'll need to worry about hp once the build it complete (shooting for 700+ lol).

About my kit and not fitting it, seriously it's killing me.... I have about £10k of parts now just sitting in box plastic boxes in my basement, waiting to go on lol. The only good new is that I might be staying in the US for a longer period (will know in the next 2 months), if i'm staying it will likely be for another 3 years, so i've already got prices to container my 15 to the states (not to register it as a road car which you can't but just so I can work on it and transport it to the garages over here for work), the charge for 1 way is not much more than my insurance, so if i'm staying it coming over here.

;) Ermmm trailor the car to Mazworx, Full Race, Apex Speed Tech, me like. If i'm not staying i'll be back at the end of the year and I can start putting everything together then...

Works Bell stuff is amazing... wish I could afford this :(


I'm having to look at NRG as it's more within my budget lol...
James, The quality is superb but the price isn't :( . FRSport have a load of NRG quick releases recently posted on their site as new additions, I think they have some good deals at the mo.

You're track car is looking top mate, one day in the distant (hopefully not too distant) future, i'll be sharing some track space with you and Craig, that should be fun.....

Cheers :)

Hey were abouts are you in Canada, I was up in Syracuse, NY last week, not to far from the border (bloody cold :)...
I had just noticed this post now :(

I'm near Toronto, so that would be about 6-8 hours from that location.

I see the parts continue to pile up? It's like Christmas every time I open this thread! :)

Nice choice with the Yoshioka quick release BTW ;)

Thanks guys, slowly but surely it's getting there, but I'm starting the realise the depth of the build I want means this isn't going to be finished any time soon :(

I'm thinking more like 24months now, but I'm in no rush.....

You've got to find the time to put it all together once you've gathered all the parts :wack:. That's all I need but never have a minute to work on the motor much anymore.

Loving all the parts going into the build though, pal. There's always something awesome being updated here.

Cheers mate, many many more parts to go :wack:

Hopefully a bit later in the year the car will be traveling stateside, so then the will be no excuse for me not to get the actual build started. Ultimately it will come back to the UK will me but not before a couple of trips to Maxworx and Full Race :)
