Challenger Posted June 10, 2009 Share Posted June 10, 2009 First off take a look at the link in my sig. Itll really help you out. :) Also Im pretty sure this will either be deleted or moved to the tool shed so heres my quick comments. Hopefully they help you and get you on your way. But I will give you some hints and info to think about. If your wanting to go to a larger turbine I assume your wanting to run more than about 13 psi or so ?(from what Ive read thats where the stock turbo poops out) If so youll be wanting to upgrade your electronics to accomodate the extra air your engine is ingesting with extra fuel. In that case your main needs will be the exhaust manifold, turbo, turbo oil lines, larger injectors, and then I assume youd run an intercooler so all the related stuff for that. (bov, piping, intercooler, couplers) Also to replace the original computer, megasquirt or some other standalone with all the accesories needed, search for more details. If you end up using the stock electronics and stock turbo, youll need again the parts mentioned above minus the standalone and bigger injectors. The turbo ecu, engine harness, afm, injectors, coil/ignitor, and downpipe. There are a few more tid bits needed but im sure you can find those with the search button.. Also in both cases youll need to consider your compression ratio. I assume your engine has a p79 with flattops. Many na -> turbo engines with the original NA compression will have trouble with detonation if you dont treat the engine right, aka fuel, timing, air temperatures, etc. So being that you want a t3/t4 again you probably arent wanting to run 5 or 6 psi. Look into getting a n42/f54 block with dished pistons, and possibly a p90/a head. Anyways, a few terms to search for... turbo swap, na turbo, l28et, megasquirt, standalone, upgrade turbo, p90, high compression turbo, etc. Be creative and choose different words and youll get better/worse results. Its all been discussed and its all there. Just a matter of finding it. Quote Link to comment Share on other sites More sharing options...
woldson Posted June 10, 2009 Share Posted June 10, 2009 Stand alone ecu, manifold, turbo, meth injec. Now understand just these basics and inquire why I may be wrong. This is for him. Quote Link to comment Share on other sites More sharing options...

FlatBlack Posted June 10, 2009 Share Posted June 10, 2009 Twin turbo header, two Holset HY35s, and stock N/A EFI? Maybe some turbo oil lines... Quote Link to comment Share on other sites More sharing options...
chrismiller5157 Posted June 10, 2009 Author Share Posted June 10, 2009 Thanks challenger, answered a lot of question's! but a few more for you if you don't mind. {please corect me at any time that i may be rong} What is the 'afm"? an i have the stock L28 none turbo motor in my S130 right now, so can i just rebuild it to meet the turbo motor spec's an do i have to shave or port anthing for these new heads??? an is it a do it your selfer's task to put a Mega squirt set up in my car or is it somthing i should have a shop do?? im not a electrition by any means. the reson i was thinking the T3/T4 turbo is because i can get a new one for $400.00 {just the Turbo it's self} now is there a better turbo kit, becuase im thinking of TRYING to make the car produce 250HP 270HP to the wheel an im guessing at 10 to 14 PSI, thats my goal becuase this is going to be a daily drive in Houston, Texas {keep in mind its hooooot here for about 4 to 5 mounth's an traffic is an issue} so i was thinking if i went over 300HP it would be a bitch to worry about in having issue's all the time. thank's.

Challenger Posted June 10, 2009 Share Posted June 10, 2009 AFM is the box attached to the tube coming off of your TB. It measures the amount of air coming into the engine via a spring loaded flap. 250-270 rwhp is close to 300 flywheel. Im not sure on numbers but Im pretty sure thats getting close/past the stock electronics abilities. (without major modifications/rigging) But dont take my word for it.
