Turbo conversion 3sge engine Options

[trackdaydavid]

hello i am thinking about taking my 3sge engine celica and converting it into a turbo, in theory mechanics said it would work all i would need to do is buy a set of lower compression piston rings from the st205 which i have been told are the same bore size pistons. Buy a celica turbo manifold and turbo and make a custom from pipe to match up with my stainless steel exhaust system. Then make a custom inlet manifold to except the turbo feed after making a custom intercooler radiator and pipe work. But i am struggling to work out how to tell the engine to increase fuel pressure when the turbo is spooling. I know that this probably sounds stupid, but can't afford a gt4 or expensive engine swops.
Also i don't understand half the engines that you quote in the conversion guide. Are we saying a st202 3sge transmission will except a gen 5 turbo top end and just need wiring comversion and fuel adjustments or am i getting it wrong. I love in the UK and cannot find many people to talk to about the car everybody seems to love the explosive RS turbo Escorts and Cosworths where i live. I have already done some engine work including piper performance cams, doulbe valve springs and piper pulleys but i can beat the rs turbo's but struggle against the Cosworth Sapphires. Any help or guide would be great as i am still getting to grips the in in's and outs of the car thanks

you can turbo the 3sge engine, as is, and run moderate boost with some VERY nice gains.

3sgte manifold, turbo, downpipe and whatnot is pretty much a bolt on affair, minus the oil feed, which is easy enough to take care of, just a couple fittings and a little welding like what is shown in my 5sfte thread.

fuel control can be a simple as a unit like the SAFCII, or SAFC neo, or as complex as a full standalone engine management system, it pretty much depends on your wallet and your goals as to which you do.

you could pretty much follow one of those 5sfte threads, and have a nice reliable turbo setup, provided you take the time to do the proper research, and assuming your motor is healthy.

if you want BIG gains, (350whp+) your better served saving your money and doing a 3sgte swap, once you factor in the cost of pistons and the associated work, + the cost of a decent turbo setup, your right about what it would cost for a 3rd gen setup, which is 300+whp capable with just intake and exhaust mods, boost controller, and FCD.

good luck.
