Forums Forums StuyMac - Honda Integra DC2 Type R Race Car

Right, few pics of the latest modifications...

Door / window trims refitted, bent these when fitting the poly windows, but managed to get another set, they just tidy the car up a bit.





Holder for detatchable steering wheel.



New inlet manifold fitted with thermal gasket.





New cams and vernier pulleys - cant see the cams, but they are in there



New layout for the intake - the manifold sits lower than std so a custom air intake pipe is required.



New Hondata ECU, now all mapped up

looking good. where did you get your poly windows from? i'm looking to get some

Windows are from Plastics4performance

Wouldnt recommend using them on a road car though, they scratch very easily, and the window slider lets very little air in the car

cheers, i shall google them now. they'll be getting fitted to my track car

Brilliant work there stu, you could eat your dinner off that engine, how clean is that!

Who mapped the ecu?

There's a pug 205 going around with those windows on, where the window trims expensive?
When my boss had a 350z one of those cost £75 to replace.

ECU Work was done by a company called RDT in Doncaster, he is a bit of a Honda Buff, and really knows his stuff with these cars; he had an EK9 with a B18 Integra motor fitted, plus a turbo strapped to the side. 425bhp at the wheels it makes - took us out in it after mine was mapped - very scary

Trims came off a breaker on the integra owners club site, so they didnt cost much at all

As already mentioned, not sure why you would want to fit these windows to a road car, they are fixed and get hot in the summer, cold in the winter and scratch very easily, so unless the car has a cage, its just a poser to say he has plastic windows

Spare set of wheels finally got painted over the weekend - rattle can and some laquer





She is also booked in with Stevie @ Grinspeed in Preston in a couple of weeks, going to get all the geometry set up following the fitting of the Hardrace RTA bushes, and also get the car corner weighted

Nice job on the wheels stu

Nice one stu looking

Quick update....

Yesterday I took the car up to Grinspeed in Leyland, and had all the geometry checked / setup and had the car corner weighted.



Car tipped the scales at 970kgs with 1/2 tank of fuel

Im doing a track day at Oulton in November to see if it all works, and the guy who set the car up will also be coming to twwek anything if Im not happy

Be keen to come and watch if that's OK?

No worries Alex, Ill have a passenger seat in at some point too, but I need to test the car with just me in it - ie race conditions to check and adjust the setup. Until Im happy with that it will just be one seat and myself in the car.

Friday 4th Nov is the trackday - we also have a garage booked.

Aw maaaaan, bad day for me.

Otherwise I'd have loved to drive over and have a look!

That's brilliant! Nice going stu

Right bit of an update - with some power graphs.

Had the ECU fitted a while back, but at the time of mapping my injector duty cycle was creeping up past 90% so Ideally I needed some bigger ones.

Going too big can have detremental effects, so I did some research and found that some other Hondas used bigger injectors, offering the same loom plug and resistance.

So, I foudn a set on ebay, got them cleaned and flow tested, then fitted them and took the car to Dan Dan0h at Auto Sport North for a bit of tweeking.

All figures are at the wheels - no guesstimate flywheel figures.

No more fuel was added either, just the duty cycle reduced to get the correct spray pattern...

Graphs...

After fitting S300 ECU with 240cc injectors...

Vtec comes in at 5200rpm.



After fitting Prelude injectors and a little tweek on the map for some cam movement.







So, a big thumbs up to Dan for twweking the map and finding another 11bhp - I could really tell there was a difference between driving the car there, and then driving it home. If anyone is after someone to do any ECU mapping, I can highly recommend Dan, and I know of at least 3 other guys I race with (who live locally) who will be paying him a visit soon for some fettling
