I'm ready to rebuild myB18 type r race engine[ used on circuit only]
have the following bits ready to go;
b18 type r jdm head mild porting, toda springs , oversize toda pistons, toda spec b cams, cam gears, standard rods[ modified for floating pins] and crank, toda flywheel, toda header, autronic programmable ecu. hopefully will run to about 8750/8800 rpm on standard throttle body.
anything missing? will i need 310 injectors?
any sugestions for startup settings for cams and ignition.
what sort of WHP should I be looking for?
interested in your comments.

 

370-440cc would be advisable
Your whp should be right around 190-200 depending on the quality of your headwork

 

I never heard of that one. Where can I find info on this unit?

 

Re Autronic ECU
they are manufactured in Australia and the designer was one of the original designers/partner in Motec.
really good product and pricing is well below motec.
Export sales are handled by Ray Hall

another really good programable ECU availabe here in New Zealand is Link
http://www.link-electro.co.nz

can recomend them for use on Honda B series engines.

are you aware that Hondata is Two New Zealand guys[ Doug and Derek] that moved to the USA last year with their product!!!

We have very few regulations regarding car modifications so many highly modified cars are driven legally on the road and many fitted with aftermarket programable ECU's

 

you will get varying answer on the recommended size of the injectors you should use. SGT likes using big *** injectors - whereas other people would say 310s or so.

An adjustable fuel pressure riser/regulator is also recommended.

 

Injector size.
yeh much confusion over injector sizes with the ''experts'' recomending from standard size up.
why is everyone going so large with hondata?
most of the circuit race guys here in New Zealand are running fully programable ECU's so stay with standard fuel pressure and vary the injector size and tune via the ECU

The japanese guys seem to stay with standard injectors !!

 

if you are using smaller injectors - then you need to raise fuel pressure by way of FPR or bigger fuel pump (L/hr) in the tank. Running higher pressure improves atomization of the fuel at the expense of duty cycle.

the whole premise behind running a larger injector is to reduce duty cycle to within spec (say 80-85% max rate) and reduce the chance of injector failure. As circuit racing involves a lot of WOT application - maybe this is a good idea.

yep in Australia as Big Al has meantioned and they are better than Power FC in both functionality and tunability!

 

How much of a pain are they to tune compared to the Power FC etc.? Curious because stateside support could be very hard to find.

 

im not quite sure on how easy they are to tune although i suppose with a knowledgeable tuner and the right equipment then everything should be fine. Motec, Autronic ECU's are one of the best in the world. But would only be worthwhile if you actually plan to heavy modify your engine. Otherwise Power FC would be more than suffice.

 

I have had no personal experience with power FC but have been told by those that have that Motec, Autronic and Link are much easier to understand and calibrate.
all use windows bases software and link also has an optional handcontroller.
they are all fully adjustable and have launch, antilag, boost control etc along with full fuel , ignition and autotune.
Autronic and link offer replacement circuit boards to fit inside factory housing so it is not visible that an adjustable ECU is fitted and there is no extra wiring required.

i have found support from Autronic and link excellent and have sorted my queries by email without any problems as you are talking with guys that have designed , built and installed the products

 

I'm using the link on my car just installed it a few days ago. It's really easy to use and i do like it a lot. If any of you have any questions reguarding the system just IM me i'll be happy to answer anything that i can.

 

I would go with both forged pistons & rods. Especially if this is a circuit only car...

BTW, this is a little off topic...

Is Wanganui on the east coast a couple of hours North of Auckland? If so, I think I went to this fish/chip take out there. Really good!!!

Garth,
you were probably at Whangerai or Whakatane, Wanganui is on the west coast about 4 hours south, but still a great place and close to the race tracks!!!

 

Oh... my mistake. I did manage to go through Wanganui when I drove to Wellington. Beautiful country. I would love to relocate there...

Anyways, your setup sounds good. I would just make sure you build a stout block with forged pistons & rods. There is no point to use factory rods with forged pistons. Also why a mild port & polish? You should just get a full race p&p job to go with the Spec B's...

Well that is my take. Like Romey... I'm out ! (sorry US talk radio reference)
