The Don Posted October 15, 2010 Posted October 15, 2010 *NOW SOLD* I bought these direct from Motordyne in Feb 08. They were on my GT4 until this September but being non-moving parts are in good as new condition. £135 + £5p&p for the 5/16" isothermal plenum spacer kit £220 + £15p&p for the MREV2 lower collector Make me an offer... If you have a rev-up engine then this is a great combo. I never had it dyno'd but the torque gain in the mid-range is significant and the car really surges on at about 4krpm. I can also categorically state that the ECU will not dial out the effects of these mods. I still have the Motordyne purchase/postage receipts if you would like proof of authenticity.
