Keep everyone up to date with how your project is coming along.
So I'll try and keep this short and on topic of tuning/engines.
I bought the car as a standard b16b(n/a) engined car with the plan to turbocharge the stock engine.
This worked fine until a mishap with a t-piece melting shut between laps of the Nurburgring, this lead to zero boost control the next time I hit the throttle so you can imagine what happened next....
So the rebuild began, I'd never rebuilt and engine before so massive learning experience, had a few hiccups with oil pumps. Basically I wasn't being clean enough with the build process.
Got there eventually and the current forged build has been running 2500miles and a good few track days without fault.
Basic specs of the engine
Manley rods and Wiseco pistons
Standard b18c head
T3/T04e turbo on a cast manifold and 2.5" exhaust system
When I had this tuned it made 350@1bar of boost.
So ran like that until recently I found the bearings in my current turbo are past their best, cue upgrade!
New manifold, gtx2867r and 3" exhaust going on with new engine management(hondata s300 v3)
So this is what brings me here, tuning this setup on the s300 then eventually on to tune others.
A couple on track shots
So that's where the cars at ATM, it's away having a cage welded in and the 3" exhaust fabbed up. Then it's tune time!
Sounds like a lot of fun on track.
Just curious, how did you choose your CR, ~10:1 seems quite high :)
Yeah it's standard practice in the Honda scene to run that high on a turbo motor. Unless your aiming for massive figures.
I wanted to keep decent drivability off boost and for my power goals 10-1 is fine.
The stock b16b I ran is 10.8-1cr.
For sure, having decent off-boost response and fuel economy is always nice, should help with spool too.
Since E85 is non-existent in the UK, I guess you will be using 98 pump fuel?
Yes just normal pump fuel.
I'll experiment abit but Shell Vpower is where I'll start.
Nice built and nice car . But I am surprised you aren't using a block guard or sleeves . Also I am curious why you didn't use the B16B head ?
When I built the engine I was only expecting to run around 350-400hp.
The cost and finding someone over here that's reliable enough to either sleeve or fit a block guard are the two main reasons I didn't bother.
The b16b head had a lot of swarf and crap in it from the piston failure so I opted to use a b18c head.
Little known fact that the uk spec dc2s and 98spec JDM dc2s have the same head as a b16b(3degrees more duration on intake cam over 96spec b18c) so in effect I've lost nothing.
Do they also have the same valve angle ? Cause the B18C and the B16A have the same but the B16B has a better chamber in general , hence my question .
As a Honda enthusiast , if you do not mind me asking , what also have you done ?
As far as I'm aware they are the same.
I'll make a list of parts etc on the car when I get home from work.
So this is the spec list I sent the insurance company last year, I've been updating it as parts have been added.
Note manifold, turbo and exhaust are being replaced this week and a 6point msa spec cage has just been welded in.

Have you also changed the final drive to a 4.4 , or kept it stock 4.7 Type R spec ?
The standard gearbox in these is an s4c LSD which has the same ratios as the 4.4 s80. I've got the 4.7s80 from 98spec dc2 in this ATM.
