Absolutely evo10.5t

Upgraded alternator ordered. Used Nathan of Excessive Amperage from R/TErnie's Interested in a high output Alternator? thread. Thanks for leading the way in that venue R/T

 

Mitsuorder this build is exceptional! It looks as though you've spared no expense and used nothing but the best parts. I'm sure you're proud as hell to have all those beautiful ToxicFab parts in that engine bay (I would be lol). I know it's a small detail but one of the things that caught my eye were those vanjen clamps which look awesome. I'm installing a FB TB soon and was wondering which size kit did you buy for it and is it relatively easy to fit? Reading through this thread you've said you're away from the car for weeks at a time. I don't think I could stand to be apart from this car for that long: Enjoy it!

 

Appreciate the kind words CDHoff. It has taken a hell of a long time to do it the way I wanted to this go around. Collin at ToxicFab went ***** out on everything he fabbed for the car. When in the country I just pop the hood and stare at it at times lol. So ready to drive the car again but at the same time know it's just going to a whole other beast. Admittedly a bit nervous too

In regards to the VanJen assembly used at the FullBlown throttle body I went with their 3" kit part # 12506 . Collin modified the AMS intercooler with a 3" outlet so we wouldn't have any transitions to the throttle body. He welded all of the fittings from the inside out so that definitely added a level of difficulty to it all. But once these things are on, they are ON.

 

ok this is just amazing im doing this to my 04 ralliart but have been hesitant to start because ive never seen it done. im am going to follow this build in my ralliart i do have a question though i havnt seen asked or answered yet. ive heard that the head swap messes with the compression ratio is this true? such as the factory cr is 9:5:1 and just the head swap jumps it to 11:0:1. if this is true how is this fixed? would you have to bore out the combustion chambers to get the right cc or just get lower compression pistons to run lets say a 9:5:1 or 8:5:1.
als one more question besides the mivec is there a huge difference/ advantage to the 9 head vs the 8 head. i currently have the 8 head but if the 9 is better/ easier with the mivec i will switch to the 9.
thanks for the help and amazing build cant wait to see more.

 

lanceresx9,

I have no idea of the combustion chamber displacement of the 4g69 head to be honest with you. I had mine massaged for a better transition to the larger block cylinder bore. If you were running oem 4g69 pistons, which I wouldn't recommend, and wanting to lower the compression ratio, you could use a thicker head gasket. I went with 9.5:1 and used a 1.5mm Power Enterprise head gasket, honestly wish I would have gone with the thinner of the offerings, and know that will lower my cr a bit.

In regards to the 8 vs. 9 head. It's really more of a preference thing. Having gone from an 8 engine to a 9 swap I liked the mivec for better driveability, especially in those out of boost areas. Simply put, it made the car more enjoyable. With that said, some seem to find the mivec useless at higher rpm/hp levels. I know there are kits made if you want to delete this feature. I guess it just depends on whether or not you have access to the head, 9 harness, ecu, and the desire to do it

Appreciate the compliment man. Let's just see how it runs. Still have to make it back, slap the new alternator on, and have it tuned. Nothing has been left to chance but you still get nervous from time to time

Thanks to the whole community. Hope this works out and proves to be a viable block option when it's all said and done

rainbows and unicorn farts,

ok so did some reading come to find out that the evo 8-9 head has a combustion chamber of 43cc and the ralliart sohc head has a volume of 55cc. so if i was to buy 87.5mm pistons with the 150mm rods and keep the 9:5:1 compression ratio. the 43cc combustion chamber would take the cr to around 11:2:1 which would be awesome for an n/a build but pretty crazy for big turbo. so since you bored your CC out to 87mm im guessing your right around the 55cc which will keep you at the 9:5:1 cr so ill have to bore mine out as well.

and i think im gonna keep my 8 head and run a aem standalone to tune it all, but dont know what turbo yet though. but thanks for the quick reply just thought i would through that on here so other people would see it and understand the cr change with the head swap considering cr is a pretty big deal lol.

 

This is looking really good, the completed exhaust assembly looks amazing.

 

OMG Great built. It looks great.

 

lanceresx9,

Dude thanks so much for the info. Guess I just never had a reason to dig up the specs So important for any of those keeping the sohc head to know. I went to 87.5 mm just to clarify. Prob just a type-o.

I guess if I had one regret at this point it's that I would have gone with the 1.2 mm Power Enterprise head gasket instead of the 1.5 mm version. Admittedly, it was a cost driven decision which might end up biting me in the a$$ in regards to compression reduction. Someone have the calculations for that? Know with the 100mm 4g69 crank and 87.5 mm pistons my displacement should be 2405 cc with an individual cylinder displacement of 601.25 cc. Don't know what the 1.5 mm head gasket would add to the cc though.

 

i do not have that info wish i did but do not cant wait for an update on the build hope all is going well keep us updated.

 

Very cool, wish I would have kept my old Lancer and had the time/money to try this.

 

Any results?!?!

 

Looks like all is a go to start tuning it next week

 

please tell me you're bringing this thing to the shootout

 

Good Luck and God speed!
