Message: <blockquote data-quote="defcon1" data-source="post: 1362042" data-attributes="member: 30064">Hello Ong...thanks for the warm welcomeI think you got it right the first time. "Freak" describes me perfectly.My first hot rod (circa 20 years ago) was a Toyota Corolla LE 1.3l carburetted. It did 200 kph and spun tyres on it's 3rd gear. Needless to say, I blew that motor within 6 months...over-compression. Converted it back to stock, and sold it... :(Since then, I've never looked back. My next project was an ambitious rebuild (interior as well as exterior) of an old Honda Accord 1.6l. This one did 230kph (not bad for a modified stock carb). It ran beautifully. Quite by accident, I got the compression ratio and flow of the head correct. I drove that around for 3 years before trading it in for a Wira. I'd just embarked on my career and had to put the hobby away for a while. But I never really left.8 years ago, I got transfered to Singapore where I first saw the Celica. It was love at first sight. BUT that project cost me a lot of time and money. It took parts from Hong Kong, Australia and the US to complete...not to mention 2.5 years of my spare time. That was an exceptional car. 0 - 100kph in 5.5 secs, top speed of 250 kph (not high considering what some BMW's do, but consider that it was a full time 4WD). I once did the KL-Singapore run in 1 hour 45 mins, inclusive one hasty coffee break.In 2002 I came home. Had to sell the car...no choice since it had S'pore registration. As I needed a daily driver, I settled on the Cefiro, kept it stock and put my money into my family and house instead. I wasn't getting any younger, and I'd started my family late, so I figured that I had "played" enough...NOT!Now that things are settling down, I'm getting itchy again. Your car seems to be doing well. FC quite good actually. The thing I respect about the Cefiro is the ECU fuel mapping. If you really calculate it, you will find that it burns just slightly more than a 2.2l cos of the very fine electronic control. The only time it actually burns is when you floor the throttle, and the car goes into "open loop" mode.I am still considering the 2.5l motor. You are right...what can you get for RM30+ these days, and this car out-does everything in it's current price bracket. If I decide to do the transplant, then I will seriously consider lobbing in a turbo. I estimate that with a small, light pressure turbo - possibly a TO4E-15G or equivalent...easily gotten off an old Saab or an Evo III, I could breach 300 bhp and still retain driveability with acceptable FC. The turbo matching would be important as too big a turbo, and all you will get is lag in the city. The 15G is the perfect size, as I calculate that our VQ motors will need about 500 cfm, and the 15G does about 560 cfm...a little headroom to make sure that it isn't over-worked.Our VQ motors come already with forged pistons, making light pressure turboing very practical and safe. I estimate that they will withstand 6 - 8 psi easily, with a maximum of about 10 psi with stock internals. Above that, and a thicker head gasket will be needed. Throughout the powerband, our ECU should be able to handle the fuel requirements. A "piggy-back" ECU will be required to handle the injector response at high rpm's when the stock ECU goes into open loop mode, but that would be about it. With light pressure, the turbo would not generate excessive heat.Anyone interested in doing this as a group? I have already completed the design and am only waiting for an excuse to do it. Usually it would take about RM 4k - 5k to complete such a project. The bulk of the money goes to fabricating custom parts like air and exhaust pipes. Buying as a group, would knock off about 30% of the cost.Oh ya...does anyone have any experience with after-market bushings for this car?</blockquote>
