thetoyman75 Forums Junkie Club President I supported Toymods Location: Sydney Registered: May 2002	Re: NA 3TG/2T Hybrid Mon, 07 July 2003 13:43 Sorry for the delay but web time is scarce for me at the moment Ok, Jonny has covered alot so I am not going to repeat it but a few small points. "By any 2T or 3T block" that includes 2T-G and 3T-GTE blocks. if you use a 2T series block it make make registration alot easier depending on your Blue slip inspector. Pistons - By "Must be 3T" jonny means they must have the Pin Height of a 3T, The extra capacity is made by a longer stroke in the crank and as such the pin heighs between the 2T series pistons and the 3T series pistons is quite signifigant. 3T and 3T-GTE cranks have the same dimensions. There are questions/rumours about the supremancy of the 3T-GTE crank and it being stronger. There is nothing I know of to support or deny this ? Conrods - These also come back to Urban Legend BUT it is a well supported Urban legend. 3T-GTE rods are supposed to be the strongest, VERY closely followed by the 2T-GEU rods. However all T series rods are good quality and should surfice. Shot peening and linishing awith Good rod Bolts (ARP) is VERY strongly recommended for anything approaching a serious rebuild. High RPM race engines will need aftermarket rods. (Use 8000 RPM as a Guide point for when Shot peened & Linished Rods might not be up to the task) Flywheels - Yes any will fit, as will a 1G-GTE flywheel. BUT be very careful with which one you choose. BAthroom scale results show a MASSIVE 4KG weight difference between the 2T and 2T-GEU flywheels. theres a thread on T series FLywheels if you wnat all the details. Cams- Depends on what else you do and how you wanna drive it. Speak to someone who knows these engines before you decide and if they are not timed correctly the engine will run like a dog. This is one area you cannot compromise on, remember these are a full impact head. If the cam timing is out Kiss all your valves and prolly your pistons goodbye when they smash into each other Compression - Once again depends on application and more importantly the fuel you will be running it on. Fuel delivery depends how wild you go, 40mm is not really the go for a BIG horsepower 2TG, 45mm or aftermarket injection with custom intake (Or Quad Throttle bodies) is the better option. Overbore - Ok this is the sticky one. There is alot of stuff about 89mm T series engines. It is possible with the right block and a good machinist. Personally I will not go past 88.5mm as I have no desire to hit the water jackets with my pistons and i don't want to go to the expense of have a block sleaved for .5 of a mm ! Head gasket - If your rebuilding an engine and an extra $50 or so for the correct one is going to blow your budget then don't build it ! Cool 1, If it were me and I were building a low to medium performer i would use a 3T-GTE crank and rods and either a late model 2T-GEU block or a 3T-GTE block depending on what I wanted to tell the engineer I do like the whole......"Its only 1600cc... Honest line ) For a BIG power 2/3TG (over 100 RWHP) I'd seriously be considering Forged rods and shooting for the big numbers and high RPM treatment (Reliable High RPM can be achieved but there are some well guarded tricks required so get it built by the right person) ! You don't get a butcher to opperate on your body, treat a high performance rebuild the same way, too many poorly built engines give the rest of them a bad reputation ! And as for Single cam verses twin cam heads, Twin Cam should get the Best results BUT the single cam can give it quite a stir. Hope that helps. [Report message to a moderator]
