FORGED INTERNALS...TURBO

Anyone know any good manufactures for forged pistons and rods.. im in the process of turboing my 98 2.0 tiburon thanks

ummm...are you buying the turbo in a kit from some company? if so, do they offer them? if not, i think that RippMods might, but i dont care for their company in general.

I have made my own internals for that block so if you let me know what you want I may be able to help.

im building my own turbo kit, i have a dsm turbo w/ wastegate, bov, manifold, gauges and stuff.. my tiburon is allllll apart in my garage down to bare block if you could lemme no what pistons you made? that woudl be aweosme

There are lots of factors and personal preferences that apply. How much boost do you want to run? Are you going to change something other than pistons, rings,rods,etc...? Depending on ammount of boost how much compression you are willing to chance?

im looking to run over 15 psi
i need these:
-8.5:1 or 9.0:1 compression forged pistons (stock diameter)
-forged rods
-dsm 16g turbine (i have a 14b compressor)
-front mount intercooler
-blow off valve (i have already)
-injectors...i dont know what size tho
-manifold (i kinda have)
-internal wastegate (i have already)
-boost controller (they are cheap, under hood ones because its just a bleeder screw basically)
-intercooler piping
-oil coolant lines(to and from turbo)
-boost gauge,a/f ratio(i have), and apexi safc

(thank god for ebay)

You have a couple of options here. You can go for a higher compression piston, or a lengthened set of rods. either way you should be able to build compression this way. A good option is a very High compression piston once you have them machine the center about two tenths on each piston that will drop you to the 9.0:1 range. make sure you machine each evenly or you will scatter the block. That would be a safe bet you should be able to cut down alot of turbo lag too. If you have the car as a daily driver pushiong a constant 15 lbs. I would drop the comp to 8.5:1 for reliability. You have a nice list of mods but one thing that I noticed was missing is fuel delivery. You have injectors but that may not be enough depending on your ECU settings. If you are using injectors in the 1500cc range you may have to obtain a fuel rail. AEM makes one that should do fine. SOOOOOOO.... get some forged pistons, check weisco, if they are flat tops then have the centers ground down. ANy more questions let me know.

wiseco only makes over sized pistons (larger diameter) and the machine shop i deal with will charge $240 to bore each cylinder so im not sure about that

my biggest problem is rods... i cant find forged rods... can i do something to my rods to make them stronger? and eagle rods don't make custom rods so i couldn't even send them out

To be honest there really isn't a way to improve a stock rods strength but the stock rods should be able to hold up to the boost. The only time you really needed beefed rods is super high compression or boost. Or if you are increasing RPM's to like 8000 or up

Could always go custom forged from a company that does that, if you're that willing.

yeah custom is going to cost more.............. and there is a way to strengthen rods, shot peening, it pretty much compacts the rod so make it stronger... tahnks guys im accually almost done with all teh parts i need and im going to be putting my engine back together this week

i have seen some at http://shop.hyundaiperformance.com/shop/cat.php?c=2 dont know how good or bad they are but they are there. i also shaow a turbo kit at www.sharkracing.com that has both in the kit, you could email them and ask them whos rods and pistons they use in there kits.

post some pics of the finished project if you can.

ok guys.. i figured since everyhting is apart in my car, i might as well do it the right way..I bored it out to a 2.2L, got oversized Wiseco forged pistons, Pauter forged connecting rods, polished head, T3/T4 Turbonetics Turbo (.46 Turbine, .63 Compressor), 450cc fuel injectors, Vortec 10:1 Fuel Pressure Regualtor, Apex-i Super Air Flow Controller II piggyback unit, all new bearings, all new gaskets, new head bolts, an lsd for my tranny and so much more i can't even think of........ im in the process of dropping hte motor and tranny back into the car as soon as i get the tranny back from my buddy's shop who is puttin the lsd in my car... im hoping to have close to if not over 300 hp by hte time im done..... cross your fingers for me guys

All I can say is. SWEEEEET!!

hi you doing bro let me give you an advice im from puerto rico here there is a hyundai accent with a 2.0 liter engine stock internals and is turbo and has a megasquirt programmable ecu and its running with 23 psi of boost and it runs 11 s on the quarter with accent transmission the tiburon factory rods can manage up to 25 depending on setting if you want to run more safer change the pistons to forged or put a wider head gasket to lower compression and with the factory ecu you can run with 10 psi safely believe me im in the same project i have a 2.0 accent and is coming turbo get an msd dis-2 to retard the spark timing and you can run up to 15 psi safely with out changing pistons and rods get good fuel injectors like the mustang ones 330cc or something like that eliminate the air flow meter is more difficult to get a good setting with that ecu goes crazy you dont need to buy so expensive stuff believe what im saying im telling you here are a lot of hyundais turbos running 13 12 11 10 at the quarter mile if you need some advice be free to ask me im here to help in everything that i can

ooohh other thing i notice you have an apex thats good to control the air flow meter thas good
