Turboed 4g63
-
all you need to turbo your car (cheaply) is the turbo manifold, turbo, intercooler and fuel control. with the dsm, you have access to the ecu, which is perhaps the most difficult thing to figure out with a lot of na-t cars. but with the new ecu, you'd still need fuel control (7.8:1 vs 9:1), so i think it would be easier to just get an afc (ecu piggyback) and play from there. a knock sensor would be a great idea... almost easier to just get a 4g63t. look around on dsmtuners, try to find a way to get an account on there so you can use the search function.

or if you really want to turbo you n/a 4g63 i have 7 bolt turbo cams, rods, crank...pretty much everything from a turbo 7 bolt 4g63....the pistons are okay but they need new rings.

I'm gonna have to disagree with out there, its not really easier to get the entire 4G63 becuase it will be alot more expensive.
The best way to do it would be to get all of the needed parts: Turbo ECU, Knock sensor, turbo injectors (450cc not the auto ones), turbo, manifold, oil lines.
If your looking to actually make power, you'd want to look at getting different cams. The NT 9:1 pistons arent terrible, with correct tuning and that higher compression you can put out some good numbers.
Your going to also need a fuel pump if you plan on running any amount of boost.
Depending on what parts you can find used, it might be sort of costly to do right. There cheaper ways to do it, but if its just going to blow up whats the point?
Might want to look in to what you can get for the car, and see if you can find a nice AWD 1G... everythings pretty cheap these days

He's already got a 7 bolt block, the same rods as you have, and the 2G head is totally different so your parts wouldn't workin his. You cant re-use those pistons anyway...

most of those are stand-alones, stay away from them.
any place that sells import performance parts has piggyback systems, they are usually referred to by name (safc, for example).
you should ignore the idea of a stroker engine for a long time, you're still learning about what it takes to build a turbo engine... gotta learn to walk before you can run the boston marathonEDIT: jim, i meant that it might be a little easier, not cheaper
and i do not believe the ecu from any turbo dsm will work unaided, due to the compression difference. otherwise i believe we're both preaching nearly the same gospel, just in different languages

Ok then right now I want to do intake and exhaust. Who makes an intake and a good exhaust: header, downpipe, cat-backDon't waste your money, you won't notice any significant gains. You'll be hard pressed to find NA aftermarket for 4G63 becuase nobody bothers...
Save your money for a turbo setup, or a turbo car if you want to modify a DSM its the only way

it didnt blow up....the was nothing blown in it....i tore the motor completely apart...and there was nothing broken....so im not really sure what went wrong...and how cant you re-use pistons?

i have used used pistons before...and that engine still runs.

out there, i think you really are out there on this one. 2G piston is gonna be a better choice then the NA piston as well as the 1G turbo piston. The 2G piston is a 8.5:1 CR ration and definatly a better casting then the 1G piston and the NA piston.
JUST BUY A DAMN TSI/GSX ALREADY.

i would recommend using the 2g pistons for turboing the na 4g63, it would make using the ecu (95+) easier... but raise the costthat's what i said, i know the 2g pistons are better than 1g, though i can't claim to know anything about the na ones

i have to agree with the last thing nick said, just buy a turbo all wheel drive one !
