Lonestars DOHC Swap

[lonestar22]

as most of you know i got a Kia head for really cheap but it has some oil starvation issues in its past life which lead to the cam being rubbed away really badly. also has a bad lifter and roller rocker. im going in there and rebuilding this badboy for some power. i got a few pics, and a partslist. dont know where this will take me yet, but maybe a Hyundai manual will be in the car as well. my plan is for this project to be complete somewhere around the end of the year. here are the pics







Partslist so far
EVO VIII Fuel Rail
EVO VIII Dipstick & Tube
Kia Optima Head w/ Valve Cover
Fidanza Adjustable Cam Gears
Brian Crower 272/272 Cams
EVO VIII Lifters
EVO VIII rockers
Topline Valve Stem Seals
Brian Crower Valve Springs & Retainers
if i decide to port & polish i may get some larger valves but i have yet to decide

well well well lookie what we have here!

finally some engine modding.

Before you do anything with that head, take it all apart and have a machine shop magnaflux it, check for warping and overall spec it out. It will probably cost you $75. That damage on the cam looks really really bad, lack of oil bad enough to cause that could have ruined the head.

[lonestar22]

yeah the machine shop is taking everything out the head, cleaningi it up, fixing the journals, and installing all the parts for me so theres no room for me to screw things up. my VRG bumper may be for sale soon if anyone wants to trade for an old style VR4

Nice. Its a step ofter overlooked. My machinist had a 2g eclipse head someone brought him to assemblem and deck it, the thing had like $1200 worth of porting and polishing, he spec's it out and its too warped to be used, unrepairable. So the guy spent all that money on porting/polishing for nothing.

what can i run to get rid of the factory rev limiter? im going to be running a maf translator gen2 but i want to be able to rev to the evo redline once this setup is done. any insight?

[Stewi]

your 5 speed already? im pretty sure just set it up to run a 3g 5speed ECU and re-flash it to ditch the limiter.

[lonestar22]

no 5spd yet, thats coming too but i want to have the head done first

[Stewi]

Yeah the issue is trying to hack the Auto ECU to change the shift points, it doesnt matter what the redline is if the ECU is telling the trans to shift at a certain RPM, you would never be able to get to redline.

nice man if you got any other questions post them up... my suggestion on valve would be to get supertech nitrate coated valves i have the +1mm i/e in my sonata head

[lonestar22]

so yesterday i bought...
Brian Crower Stage 2 Camshafts
OEM Mitsu Valve Locks/keepers (why not?)
Topline Intake/Exhaust Valve Guides
Topline Valve Seals...

next on the list is valve springs roller rockers and lifters... and maybe valves. if i get +1mm valves does it have to be on a port and polished head? or is here some way i dont know about to make them fit

I wouldnt order valves or guides until the machinist inspects the head. I know a few guys who bought +1mm oversized valves, had the head spec'd and found out that they could only run .5mm oversize valves due to the edge of the valve being so close to the sealing area around the cylinder. This is typically only an issue on heads that need to be milled down a fair amount to achieve the proper surface finish and flatness.

[lonestar22]

i got an amazing deal on the parts, but no pics since most are on backorder.

[ricky_db]

i wouldn't trust anything back ordered rite now the way companies are disappearing these days

[lonestar22]

ill kill if my money disappears

[Stewi]

ill kill if my money disappears

as long as you didnt buy them from 3058g you should be OK.

[lonestar22]

what is this piece back here?
mine comes out sideways and spins around if you try to unscrew it. what does it do?

[lonestar22]

so this thread is also turning into my manual swap thread now. i went and put a deposit in on a Hyundai Sonata transmission due to the price difference and how close it is to my house. So far no one has tried it yet and there is only little proof that it will fit but we are soon to find out. I still need pretty much ALL the other parts of the transmission.

heres the list of parts i THINK i need. there might be more if so let me know.

Hyundai Sonata transmission
Clutch/flywheel
Master Cylinder/Slave Cylinder
Clutch Lines
Shifter Plate
Shift Cables
3G GS ECU or EVO ECU
