Ahh fair enough.

Where you getting that mapped?

Rising sun performance(again)...south west of London!!

Have you got your new ECU yet?

Is your old one worth anything with that chip in it? It might offset some of the costs. Did you say it was Buddy Club or someone like that? A JDM name whore might have it.

Buddy club mate...but the map is unreadable so no one knows what its set to do boost and power wise...

Well,I went all the way to Rising Sun Performance (249miles each way) for the second time last weekend.First time I went to them a month ago I was let down by the car as the standard ECU in the car was found to have a Buddyclub chip in it and it had damaged the ECU so that it could not be read or mapped!

Anyway this time I had a new ECU with me and the mapping started straight away...until they started full power runs and discovered it was running very poorly and the graphs were all over the place.They spent hours lookin through everything and found the trouble to be a faulty CAS unit(cam angle sensor)
On examination it had been chewed up by the pin that drives it from the exhaust cam and the pin had actually snapped off the cam!!
The reason this had happened is that a gasket with spacers in it had been missed out when the engine had been assembled! This gasket should sit between the cambelt cover and the cas unit.Without it the cas was being forced towards the cam too much...

So they fitted a new exhaust cam and found yet another problem...the bottom pulley had no woodruff key!

Anyway after all this had been fixed and the engine was all back together they said it could be mapped, but not until the next day.So another night in a hotel...

The mapping was finished the next day and I have to say it drives much smoother and pulls much better...but there is another problem... the walbro(if it is a walbro) in the tank will not supply enough fuel for more than 1.2bar without making it run lean over 6000revs....So I am gonna need to pop a relay near the pump and uprate the power supply to the pump or change the pump.

Anyway it was not all bad news...it still made 350bhp at 0.7bar..........410bhp at 1bar...........450bhp at1.2bar but not taken over 6k revs.
So it will make a bit more, but I need to sort the pump to run more boost.

I have also fitted a very free flowing exhaust which gives a much deeper and slghtly louder note...

Total expenditure for the 2 days was £1,210...nice

Nice figures, but not a nice price

I have now hardwired my Walbro so should be up about 30BHP on previous best.(480bhp)

I had 10.7volts at the pump before I fitted the relay,and now have 13.9volts at the pump!

The pump now delivers approximately 40lph more fuel, and should stop it running lean at the top end when running 1.2bar or more

Was it running low on pressure before mate

40lph wont make any difference unless it was struggling for pressure as the fuel pressure regulator on the rail will just send it back to the tank

Rising Sun said enough fuel was not being delivered to the rail...so this should sort it mate...

Happy days.

Will you be getting another RR session or are you happy as it is?

Are you competing next year or are you still busy with the baby? Hows the baby doing aswell?

Doing the full BDC season next year,I will have all the safety crap fitted by then...

S13s' are not heavy cars-so it is stupid and ridiculously fast;when you can get the power down!

I will have the fueling checked on the next group rolling road session...

Heres some pics of those steelies on the back with 10mm slip on spacers. ET28 6.5j then i think. They look better then prefaces imo. Only pics i have sorry. The front are standard teardrops no spacers so you get an idea how they sit.

Get a thread up with your other car aswell! I wanna see what you do to it.

Sound Dave,Cheers

Well,as some of you seem to be interested I Will attempt to list some of the jobs I have done to my Drift car over the last few months...
PICS will have to wait for now,as I didn't take any at the time,so will have to,just show you the areas completed...

Adjusted and balanced the throttles as the RB26 runs individual throttle butterflies for each cylinder

Fitted adjustable front tension arms so I can get more castor on the front,so the wheel self centres harder,and allows for a little more lock without over-centering issues

Moved heads up display to on top of the dash as it's easier to see there(was in front of binnacle)

Welded front cross member and strengthened it,as it was torn on a track day by the steering forces and the rose-jointed tension arms

Fitted bolt on adjustable front spacers as the wingers are 30mm wider than standard and I need as wide as possible front track for front end grip etc

Fitted 3 different exhausts till I found one that I was happy with!!...first was too quiet,second was cheap twin box jobbie-but still too quiet,and third is single box 3.75 inch bore and actually makes it sound like a skyline-engined car should!!

Moved wiring up into the top of the wing as the wheel was catching it(it had rubbed right though and wires were fusing together) as the car is pretty damn low(for handling reasons)

Adjusted warnings on the Defi gauges so that I get warnings(audible and lights)for oil=>120degrees,water=>100 degrees,oil pressure=<1.5 bar

Adusted drivers and passenger seat angles and heights for ideal driving position

Made catch tank and filter for breather hoses to stop oil entering intake hoses

Fitted adjustable rear toe arms for 0 degress rear toe

Adjusted throttle stop as tickover was too high

Bypassed aac as idle was still to high...very common on RBs

Removed thermostat as engine temps get far too high when drifting!

Fitted the most powerful 12" fans that you can buy to aid cooling while drifting.My old fans(3 12" spal fans)were just not up to the job). These are Kenlowe very high output fans and are £115 each!!

Fitted revotec fan controller for one of the electric fans and wired in manual dash switch for the other fan

Fitted relays to the fans so wiring is protected and current to fans is stable

Flushed and blead entire cooling system and added water-wetter to aid cooling...no antifreeze as it raises temps

Removed unwanted DVD screens from sun visors and replaced with standard items

Balanced actuators on the turbos so boost is equal from each turbo

Fitted mini breather to intake hose were standard breather used to be

Fitted Tein up ratted rods and rod-ends and spacers to allow much mre lock than standard

Cut back steering bump stops to allow more steering angle availble from Tein/spaced rods

Fitted new steering boots

Adjusted coilovers to lowest that I can get away with and still actully drive the thing lol

Fitted new wheels(Rota GTR 18x9.5J) and internal drive wheelnuts

Aligned wings with bumper and headlights as they didn't sit correctly

Securred gauges in glove box so they faced driver and did not slide arround

Rewired stereo so speakers were in phase

Rewired cigar lighter as it was faulty

Realigned doors so they shut more easily

Removed half of the engine,sent it away to be polished and then refitted it lol

Set up electronic boost controller for maximum effeciency.Boost gain,scamble,warnings,displays etc etc

Fixed dodgy fuse holder for HIDs

Spaced antiroll bar so it doesn't tap the sump

Uprated engine mounts with bolts to go through them as well as welding

Removed half of the engine,sent it away to be polished and then refitted it

Removed fuel pump and replaced with new walbro and hardwired it

Removed binnicle to fix incorrectly set petrol gauge(used to run out at a quarter!

Fitted new gearknob and gaitor

Moved washer bottle wiring and repaired it as the wiring and tubing was worn through by the tyre hitting it

Moved various metal, under wheel arches, out of way of the tyres; as on full lock the tyres caught the body in about 8 different places

Cleaned the engine block of grease and tyre dust after every drift event

Bent the brackets back to shape(that hold the rear of bonnet)after the bonnet flipped back at a trackday

Fitted metal ducting under intercooler(welded and bolted in place)to supply more air to the radiator

Bend brackets back to shape, (after clipping a cone on a drift day)that hold bumper to inner arches

Fitted, then removed, rear fog light for MOT

Fitted front and rear private number plate that says my daughters' name!!

Refitted bumper side repeater lights as they used to remove themselves at anything over 150mph,or on really harsh bumps

Cleaned various parts under the bonnet and under the car after drift days,so that you could actually tell what they were!

Fitted snap-off spacer boss for steering wheel and wired up a horn button

Rewired alarm over-ride/check button to centre console

Fully serviced engine with Pro oil

Painted all brake calipers to a high standard(6-7hours)

Changed and blead all brake fluid

Adusted and serviced hand brake..essntial to get my BDC licence

Had car fully aligned(all adjustable arms) at DemonTweeks
