590Rwkw Ba Xr6t Sedan

Recommended Posts

heya guys thought id do an update on my build as its going. so I ended up going 6 speed manual. conversion was very very easy. wiring was easy (I have reverse lights) only problem I came across was the centre bearing OD being different. anyways long story short I ended up getting a yellow sticker so in the process of getting this back on the road. vehicle is getting a few changes to comply and be registered and also for extra power after registering. Full spool is coming out and am replacing with a Harrop Truetrac. standard tailshaft will be removed and will be upgrading to a DBS custom tailshaft. 1.00AR rear housing will be getting replaced with a 1.15AR housing(due to rear housing causing restriction on last tune) Brakes are being changed to be more suitable for the power. picking up a set of Brembo 6 Piston front calipers with 355mm front discs and Brembo 4 Piston rear calipers with 330mm discs. once reregistered going to be doing the last tune for this setup. aiming for low 900rwhp at around 30psi. this will be the last tune on this vehicle as injectors only have another 15-20% left. also a few old suspension bushes will be replaced to improve handling.

While you have the diff out why dont you consider a diff ratio change. For that power 3.23 would be perfect.  I have 100kw less than you 3.73 and the first 3 gears are useless , just wheel spin. 4.11 would be crazy.


I will be changing mine soon ( but mostly for less gear changes at race wars).

I got 285 invo and 1/2 throttle 3rd and it spins. Even in 4th it will still spin if I dont feel it in gently. Your car must be crazy. I just drive around using 1mm of throttle and keep it off boost to go to the shops......


I gather your on 98 with those 044s. Bloody noisy pumps.. glad to get rid of mine.

heya mate nah runnning e85 matey. :) suprisingly with the 585rwhp auto it was more tailhappy then then 790 manual. I lost a fair bit of wheel torque plus its alot more linear compared to the auto so it just goes. of course it spins 3rd but it still picks up speed really quickly and it just goes straight doesnt start hooking sideways


I just got these brembos on today im so happy hrHwACl.jpg
