I'm hoping someone has an idea whether an efi plenum and manifold will bolt to a 2a/4a motor. ECU and MAF sensors aren't important(going aftermarket). If not ill carve up the old manifold and weld flanges to throttle bodies. And also the difference in cam profiles between the 2a and the 4a. The only part of the engine i haven't touched yet is the block. After 225,000km's it has in the last six months after a timing belt snap started to blow small soot at cold start. My intent for the engine is to strip to basics and replace as i go. Wish List 1295 -> 1190 - 1185cc re-sleeve'd block Slimmer decompressed pistons (not sure of exact dimensions, still alot of number crunching to do) Head shaved, ported and polished Titanium Valve springs Titanium valves & guides Lo-Comp Pistons peened conrods Ground and polished Crank Oversize sump twin GR28 BB turbo's Custom intake and plenum Custom pipework 2 3/4" Mandrel bent exhaust resonator and single Baffle the 2a motor that is in the vehicle at the moment revs to 7200rpm I'm aiming for around 9,000 - 10,000 RPM. Interior is super stock so i'm going to rip out the old dash, seats, carpets and Retrofit newer model interior or go my own way and design from scratch I will have pics as soon as i start the job, I am currently waiting on a 4A-FE to transplant as this is my daily driver. Engine will be first, then running gear Interior and body will be the last step I'm planning on stripping the car to the barest of basics and 1/4 Mile testing the engine. BONZA
