Have you thought about running an LSD? My turbo'd GTE run's a Quaife ATB and really transforms the handling
MG “Mad Maestro” Spec Sheet
Std block, head, pistons/internals, etc
Std exhaust manifold with t3 (cossie) turbo and custom full length 2.75inch exhaust with a 3 inch tailpipe.
Custom inlet manifold built from a combination of a carb manifold cut to basics and extended with raw ally and efi manifold elements and drilled and aligned injector holes, much wrapping of the exhaust and inlet manifold and injectors/fuel rail to reduce heat soak.
Cossie 4wd intercooler modified to fit in front of the rad with some of the pipe work wrapped to reduce heat soak.
Currently running mems 1.9 (rover 600ti) management with wasted spark ignition, at 12psi boost. Fuel pump is a 400bhp cossie item with independent pressure regulator.
Greddy profec boost controller (in-car electronic). Battery moved to the boot to accommodate the air filter. Custom built high tensile head bolts (allen key heads), and allen key cam cover bolts.
Std k7 gold label (steel caged bearings) with std turbo drive shafts. Super clutch 7 ¼ inch twin plate clutch with flywheel modified to accommodate it. Soon to have high spec thrust bearing.
Std rear brakes, drums etc
Fronts have usual 280mm disc conversion (g60 vw) with cossie callipers. The servo was thrown out and replaced with a full power brake system from an early bmw, this system is complete with an accumulator and power steering control , on a brake tester this pulls up at 750kilos each side on the front and 350 kilos each side at the rear, this equates to approx 150% efficiency, this is above abs systems but much easier to lock up so you only have to breathe on the brakes to stop.
Wheels and Tyres-
Wheels are MGF Abingdon 7x16. Tyres are 205/50x16w toyo t1r on the rear and Goodyear f1 on the front. Tyres allow a 6% increase in gearing/speed this reduces wheelspin and makes your speedo more accurate.
Triple core radiator, secondary radiator to cool water from the turbo, before re-entry into the system, electric water pump to assist water flow through the turbo. Two kenlowe fans on the main rad one of which is wired to the ecu and the other is an independent 2 speed unit, secondary rad has a fan connected to the the 2 speed one. Some pipe work is custom built for the job.
Lowered uprated springs, gas shock absorbers. All std bushes at the moment, still considering poly bushes. Adjustable front camber bolts fitted.
Std red carpet and seat belts. Rover 800 electric front seats maestro vdp grey leather rear seats, all retrimmed with red pinstripe, door cards retrimmed in two tone grey vinyl and red pinstripe. Rear view mirror removed and replaced with rear view camera.
Std maestro shell with extended modified montego sills and rear arches, matched wings to sills. Twin headlight conversion made from scratch using Capri/bmw e21 inner headlights and e30 projector style outer headlights with full hid conversion (full projector and controller from a late Mercedes). Turbo top rear spoiler added. Painted in post office red. Custom MG badge (modified MGB alloy badge). Radio aerial hole welded and smoothed, delocked doors.
4 tweeters, 4 six inch bass mids, 1 fifteen inch jl sub, 5amps, 2 crossovers to control front and rear. Head unit replaced with dvd/cd rom. P4 mobile computer with 4.1 surround sound, wireless, Bluetooth, tv freeveiw, dvd, 8inch touchscreen monitor and most other home system capabilities. Rear view is linked to computer with extra positions for other cameras.
This car has until now only been on the rollers once, 12psi running very rough as it was to rich and very lean on boost, 204bhp @ 214lbft, since these readings the manifold was built as the rollers showed some problems with its breathing, at this point I could not fuel 6 psi of boost but it felt quicker and idled better, then proceeded to sort out the fuelling the best I had it was 14psi with an mf2 system running 2 cossie 570cc injectors, it ran 0-60 in approx 5 secs, quicker than an m3 evo (e36), at this boost it ran very lean above 4000rpm so they came past me at 110+ mph. but still had a top speed of 160mph+. At this point I have had problems with every clutch I have fitted std and modified the torque just rips them to pieces, this is estimated to be approx 280lbft. Hence the twin plate “super clutch”. Now that the mems system is fitted and working I think its at around 200 bhp@10psi and slightly higher torque it has become very drivable and almost feels like a std car, but am only currently running 12psi this is because that is a safe boost pressure for this system, this also feels quicker than 12psi with the old system because it revs cleaner and higher. The next enhancement now that most of the bugs are sorted out will be an emerald ecu with 3 stage boost 10/14/18 psi. This will hopefully be as far as I go with the power I think at that point it will be enough “for an old banger”. I will then concentrate on the suspension to reduce roll etc and under steer.
