3T-GTE Regular Location: Melbourne Registered: August 2003	Bang for buck Fri, 29 August 2003 05:20 Greetings all, This is a bit of a long read, but hopefully an interesting one... questions are towards the bottom.. I currently own a 3T-GTEU powered TA-22 Celica & have it set up quite well in the handling & braking departments, but I am evaluating different options to improve the power output. I am looking to develop an engine that can produce at least 300rwhp / around 430flyw hp with a "useable" power curve - suited for circuit racing. Reliability is also a crucial factor also. I am looking at continuing to super sprint it at Phillip Island, Winton, Sandown & Calder (if it is still available??) The choices I have been investigating are: - Rebuilding the current 3T-GTEU - Selling off the 3TG & replacing it with something like.... - 3S-GTE turbo & rebuilding it - SR-20 - 13B Turbo - try shoe-horning in a 2JZ-GTE Given that I already have a working standard 3TG in the vehicle, this would be my favoured option as I would not need to go out & purchase a new engine... but, if I can't get the right HP out of it, then I may as well start-over with something new. I would be looking at doing the labour myself & have built many successful naturally aspirated race engines, from 4A-GEs to 13B bridgeports, but I don't have a lot of experience with Turbo engines. It used to be my daily ride & I had the 3T-GTEU / Supra 5sp / custom diff / adj front struts / custom brakes all engineer approved around 7 years ago when I lived in Adelaide. Since I moved to Melbourne I found it wasn't very "traffic friendly" or "speeding fine friendly" so I decided to use it for track use only & since then has not been registered. I have built the car so far to IPRA regulations, but I am currently not really concerned about which category I run it in, as long as I can run it in some super-sprint category (even if I am in with the "big boys") Eventually, I may be looking to ad a restrictor & race it as a IPRA vehicle, or maybe go full on into a Sports sedan...but I would prefer to have some more fun just sprinting it without having it restricted for at least the next couple of years. Currently I am running the 3T-GTEU on a LPG GasResearch setup, & is tuned (ignition timing / curves) have been setup to run on LPG only. It does seem to work quite well, especially seeing that the GasResearch Throttle body is quite large. Comparing it to a couple of mate's 3T-GTEUs it also seems to go a bit harder (as I always seem to leave them behind).. but that may also be another factor. My question was, has anyone ever played around with a Performance LPG setup, either GasResearch or LPG injection? I was thinking about a raw LPG injection (not converted) & using the cooling effect to allow me to run higher boost... if it was somehow possible to meter it accurately enough?? From what I have heard LPG is actually quite high octane (120??) which also makes me wonder if I could run some other "special mixes" like pure propane or some other stuff that may be available (it will also come in handy if I want to have a BBQ too!) If anyone has ever experimented with anything like this, I would be most curious to know what works & what doesn't? Can anyone recommend which "path" I should take that would give me these results, while keeping it to a decent budget? I am particularly interested in anyone who has faced a similar choice already & could share with me some of their wisdom. Another issue, if I go for anything else than a 3T-GTEU, I would need to start back at square 1, sell off the current engine & re fit the new engine etc... with all that is involved in doing that, I wonder if I could better spend the money on the 3T-GTEU instead Cheers... 3T-GTE [Report message to a moderator]
