New Engine Build by MB Tech Motorsports Reading - Celica GT4 ST205
After running into coolant pressurisation issues during first mapping it was clear something wasnt quite right with the car. Seems Incorrect fitment of the Head by the previous owner/tuning company lead to a leak in the Head gasket over cylinder 2. Some ovalisation of the bore also occured (not sure what came first however), and not wanting to rebore any further means that block was now scrap metal. After meeting Marius at MB Tech Motorsports and evaluating the best way forward to gain best power and reliability the decision was made to fully rebuild the engine using a later Revision 4 3SGTE Block from the Caldina ST215. Having just received the brand new 86mm Forged CP Pistons all parts are now ready for reassembly. We do believe that this will be one of the very first GT4's in the UK to be using a REV 4 Caldina Block. Now you know why there hasnt been that many new videos to date :(

Celica GT4 ST205 Forged Engine Rebuild Running issue
Fresh forged engine rebuild, Cam timing spot on, Ignition timing spot on, No vacuum leaks, Recent new Dizzy cap, Recent new rotor arm, Recent new HT Leads, Recent new fuel filter, Fresh petrol. Engine stutters as soon as throttle is applied, dies half the time or stalls when coming back down from revs. omce holding an engine rev, the engine does not keep a flat rate but fluctuates up & down roughly 100rpm. IGNORE THE RATTLING NOISE - I have a big rattly fan turned on behind the car blowing the Exhaust gases out of my garage.
