I knew it was inevitable but didn't think it would happen so soon.
Link to my turbo upgrade thread Turbo Upgrade...please help
Brief background info...a month or so after my turbo upgrade and tune I started experiencing a rough idle after being wot. Not to long after the rough idle i would have a cylinder 2 misfire cel. Talked to my tuner and we got my car idling like a charm.
The second week of August I started having cylinder 2 & 3 misfires and here's my story from there...I was driving to a brunch for work (8/16) and was running behind and I must admit was driving fast/aggressive. Anyways I wasn't paying attention to my tach and bounced off my rev limiter in 4th gear...bad i know I came to a stoplight and she was misfiring like crazy. Fortunately my tuner was in the area and after my work meeting drove over to his shop.
The drive over there was horrible as I started having rod knock as well as my cylinders misfiring every 5 secs. When i made it to Mike's shop he checked it out and told me what I already knew...that it didn't look good at all. Haven't taken the motor apart so don't know exactly what is wrong but thinking its a ringland or rod bearing?
On to the good news ...getting my motor fully built as well as a little drivetrain work and this is what I have so far and want to know what you guys think.

Depending on the status of my turbo I'm thinking about upgrading from the Dom 2.5 to the Dom 3.
ACT SB5-HDSS clutch kit
Stoptech Powerslot Rotors
Hawk HP+ pads
Any feedback will be greatly appreciated! The build should hopefully start next week but want to finalize everything first.
Things to note are in green...What are your HP goals, because a lot of this stuff is a waste...Personally I'd avoid all Cossie and BC stuff...
Damn man, sorry to hear the problems. My engine is being picked up by my tuner this friday. I can't wait to get it back. Its been taking forever. It sound like your just about following my foot steps. LOL, my tuner is upgrading me to Dom 3.0 should be a XTR also. I have head work and cams done on mine as well. My tuner used GSC stage 1 cams. But, my goals are not as high as yours. 375-400whp is good enough for me...on pump of course. They used new iconel valves for my heads and all sorts of fun other stuff.
Cosworth was bought by another company about 2 years ago or so and have been turning out poor products as of late, mostly cams.
Kelford is a excellent choice and I highly recommend them. As far as pistons, I am bias, but I use Wossner and have had very good results with them. Less piston slap on cold starts and smoother idle in my experience.
What size exhaust housing are you planning on running with that GT35R? Also do you plan to run race gas to hit 500whp?
He runs E85. But, since I had shavings from the bearings ran through out my motor. My tuner started out with new everything for the most part. Since the shavings even got in my turbo.
New EJ257 shortblock
Carillo Pro-SA lightweight rods
ACL Race bearings
CP pistons that are side coated
Used my existing Heads just:
ported and polished
new valvesprings, retainers, seals, and inconel valves
GSC S1 Cams
OEM Master Gasket Set
OEM Oil Pump
Timing belt and tensioners etc
OEM Oil filter assembly
OEM Oil pan
Dom 3.0 (should be a XTR for rediculously cheap upgrade)
Yeah, some of that is completly unnecessary. But, since its shavings in the oil system...its all getting replaced beyond my heads. Which were tanked and cleaned.
Nevermind I have to break the engine in and then get it retuned for all the goodies. Which before it gets retuned my tuner is installing a custom FMIC with one of their IC cores. My tuner claims they run the highest quality cores out there. Garrett or Custom made ones just for them. Which they have been making EVO FMICs for a while and are shipping quite a bit of FMICs for EVOs everytime I am in there.
Research and do what you can afford or think is necessary. My car isn't going to be balls to the wall. So, my choices may or not work for you. Balls to the wall should probably have a sleeved engine or a closed deck engine. That's one thing I think you need that I might be able to squeeze by without.
PS: This is my estimate...things might have changed once they got to the work. This doesn't include the break in oil and filter with a change of oil after its broke in and new filter. Cheap...compared to the rest. We'll see what happens when its all back together.
No...my valvesprings are going to be upgraded to handle a raised rpm limit. So, I am assuming the rest of the stuff is good enough because I don't hear anyone saying they had to upgrade the retainers and seals. Just want new to complement the other new parts.
CP Pistons are known to handle a good deal of horsepower. I'm sure some other people use other pistons at a high horsepower that might idle smoother. Which is why I am getting my CPs sidecoated...it kills some of the piston slap. That's the only slight problem with CPs and with side coating its not that bad.
Which exact valvetrain my builder went with is not quite known to me. But, I am assuming its good because this guy builds engines for other SCCA road racers and rally. He is a old aquaintance of my tuner from back in the day when my tuner was still road racing. He agreed to build engines for my tuner but does not want to make his name public. Chad (my tuner) said he already got two EVO engines back from him and they ran the smoothest that he has heard after break in. Chad has used every big name engine out there on EVO from Buschur, AMS, and others. So far he said that this new guys engines run so smooth on the dyno after break in that he prefers his engines now over other engines.
My tuner gets IC cores in from Garrett and another place that makes high end custom IC cores. They make all the pipes because they have Brent who fabricates, welds, and does some metal work. So....I'd probably get TurboXS FMIC if you can't get another good brand name FMIC. They are known to be pretty good. My tuner just says the cores he gets are normally better than the crap that is on the internet.
How much boost that I am going to run will depend on my tuner. He normally tunes for a good useable powerband for driveability. But, I'd like to think I can get that with 375 or 400whp with my mods on 93 pump.
