Hi Guys,
Some of you may have seen that a couple of us MGB owners were experimenting with a 200-6 transplant into an MGB. I'm one of them...
I have a 1967 MGB modified to fit a 200 t5 combo. The engine sits back nice and far and also quite low so balance should be good. The engine/trans combo actually weighs less than the original 4 banger thanks to thin wall casting. I have also fitted a coil over 4-link rear end and corresponding front suspension and brake modifications.
I have an aluminum head on order with Matt, Turbo curved DUI Distributor and am likely going to give the FiTech 600hp power adder fuel injection unit a go. It is on the large size for a NA 200 with aluminum head but should be in a good space with blow through turbo setup. Is anyone else running one on a small six? I have a custom grind cam from Schneider with the following specs:
intake 280 duration 220 @ .050" .450" lift
exhaust 270 duration 214 @ .050" .440" lift
114 lobe center
I picked up 2 Holset turbos to start the build with and will be running a front mounted intercooler. One is a HX35 with about 100,000kms on it and the other is a low mile rebuilt HY35W (internally wastegated). From my research the HY35 and HX35 wastegates are set around 17-20psi from the earlier cummins. Is anyone running a similar sized Holset with the internal wastegate? If so were you able to adjust the actuator far enough to get boost psi to a more reasonable range? What PSI are you finding it boosts to and can the wastegate keep up with boost creep on a 200? I am planning on using the HY35 unless I find it too small on top end then may just switch the exhaust housing/turbine to something more appropriate.
If I don't have to go to an external wastegate right away I would rather not for simplicity. I'm sure I'll have plenty of kinks to work out with the entire setup and having a more straight forward exhaust setup during all the in and outs will be preferable.
Thanks, I would welcome any input and advice. This is my first foray into the Falcon six and turbocharging but not my first engine build. I have gone through a few high performance ford big blocks and mgb engines.
