After much math and asking smarter people than myself 1.5mm had to come out from all the ports and 3mm from the inlet manifolds. 6 hours more .312 cfm 12mm lift honda port numbers

So now all the ports are done i had steve at EFI hardware do a dummy tb to do some tests.steve made up a 55mm itb with a tapper down to 52mm .the aim of my test was to see how well the tb would perform on the os head would it drop much ..what bell and shape would flow best .and how much did the thratal shaft and blade hurt flow ..these tests are hard to work out some times and most times you walk away not knowing what to do . But in this case i got a few good ideas on what the tb liked in the bell shape and which way the shaft needed to be set up.and how long the manifold wanted to be to flow the same hp as the head ..the last test of the day i removed the shaft and butterfly. To my surprise it only picked up 2 cfm 301cfm from 299cfm.all going well 445 to 450hp is on the cards at 8500

Bit more progress today on the block all painted up .and concrete in. few weeks then of to get some bores done

Its killing me gordo porting is not my favorite thing . I know how its done but its so painful to do for me . Cnc is the go or les Collins . Only way to go

Getting there all ports done and flow tested average hp is 455 .very happy with the results its looking great .just need a bit of chamber work and then it can be waterjet blasted ..

305 cfm and the right x section for 8500 on the 3.35 makes 460hp ..thats crazy hp if i get to 450 its just going to blow my mind ..im loving the build ..lots of mods to the block oil feeds for exhaust cam .and water ways .its a bit of a challenge.

Lots getting done block prep work is well on the way . And ports are looking fantastic. Port flow is at 305 cfm through the intake. Steve at efi hardware is making a custom made set of itb for me .they are great to deal with .and clive cams are building a set of custom made billets for the new now very high flowing head ..its going to be very special

Ports are looking very nice now its taking some time to get something that works on such a big engine. .

It really is a drivers car .built to drive in any situation. From a quiet drive in the country on any fuel he finds . Or go to the track remove the traler and fit some race tyres and kick ass all day then drive her home .its still got a heater and stereo carpet and full dash its a road car .not a full blown racer ..if it was 500lb lighter like the gtu cars .i hate to think how fast it would be

The video was of me in a hako at full nosie having a ball ..i will put it up soon i did get to drive all of the cars in that video even the toyota. What a cracker race car that is

Haha yes mossy i was having a great time . I have a big job ahead of me getting this head to flow the air i want .but its there.i have the x section to get it to rev to 9000 on the 3.4L just need the itb to be 55mm and the pipes to go with it .

Something to aim for .i was lucky enough to get a drive in this rocket all i can say is the sound was out of this world one sexy sound track

Yes not to many zed fans in the USA will go the extra mile to build a L motor right. Gregs one in million

Thats fantastic. Thats some car your going to have .

The car is owned by one of the best blokes he just loves the car so much .how it come to be is not what this is about . The work done by all involved was driven by wanting to build the ultimate road race engine package. In the end les Collins racing pulled that off. Something that im so very proud to have been part of .

I have cut aways and seen the size i can safely go. The head of os giken engine department spent a day with me showing all the tricks .

Many hours to go .and have to make a new set of valves .5 mm up in size to make best use of the seats .so its very possible theres 450hp flow .that will be one cracker L motor

So first day back i had to know how well the os24b1 head flows stock and then with a good port to clean up a few problems. Well first time on the bench it was quite clear the port was very small .and went in to choke and stoped flowing at 350 thou lift but still flowing 376hp . Next i spent several hours doing the port and fixing the seat area. Well i was very surprised. 440hp flow first test ..i think 450hp flow is not going to be tuff to find

Haha about 57kg over had to pay lots

Having the best time in japan so many cool things to see .spent 2 days with the people at os giken factory. Just great people. And there motors were fantastic.

Yes its not going to be 50hp it needs 500atw to be fast

Good stuff gordo .just needs 200hp more and it will be a monster

Well im flying over to japan next week to spend a few days with the head engine man at OS and then spend a day with the engine man at star road .so lots of pics coming up then the hard work starts .first up flow testing and then making the exhaust pipes .no small task .

Engines at LCR getting its motec wired up not long now mate

Working on the block this week. .making room for the 90mm stroke ..next week im flying over to japan to see os gikens engine man and get a few parts ..things are getting serious. .going to be a dream trip
