im fighting between an AVO turbo or and STI...
there is a big difference between work invovled.
but whats the reall winner here
with gain of horespower?
future power upgrades?
the AVO is a great kit......slap it on in a weekend and you got some power....i would love to do a sti swap on my 99 rs too but i dont have the money or the time. i am currently saving up for a AVO turbo kit and planning to install it myself. im also considering the FAT kit but the AVO kit sounds more fool proof to me. when i was looking into a v5 sti swap for my car, it was getting way too expensive for parts and the wiring work was ridiculous. ive heard many good things about bolt on turbo kits and its possible to drive your car daily as long as you drive with common sense.
So let me get this right:and i dont know what all these people are talking about when they say you've maxed out the engine with a turbo kit.....with a turbo kit you have 2 weak spots, the stock internals and engine management.....but if you replace the internals with sti stuff or forged internals, or if you want to do it simply buy a brand new sti shortblock (1750$) and throw it in....then you have to tackle the engine management....which is easy if you spend the money...for 1800$ you can get a plug and play hydra which you can install in 30 minutes....then boom...you are good to go.....while the engine is out get some delta regrinds (like 200$)....and you're good to go....
so the avo kit is what 3500$....and then for the upgrades down the road to allow you to go with a bigger turbo its another 3500-4000$ (if you go most expensive route possible, it can be done for much cheaper but i dont want to get into that right now)....throw another 1000$ on there for a bigger turbo and supporting mods(injectors, fuel pump)...and you are at 300-350 WHP easily........
donor sti for 4K can be done.....but once in a blue moon....u cant count on it when planning your build....i thinking the wire splicing for the sti swap is a lot of work compared to a bolt on turbo kit. not to mention the actual labour work taking the stock engine out and fitting a sti engine and other parts. its definately not easy.
both set ups will not be as reliable as the stock rs. thats really obvious. i dont want to argue which will be more reliable since they are both unreliable as you are changing the stock vehicle.
finding a donor sti for $4000 is nonsense by the way. even my girlfriend laughed when she read that.
once you rebuild the motor the cost grows very quickly.....and at that point you're better off just rebuilding the stock engine with better internals...as the same work on the RS block eliminates one of the two barriers to turboing the RS^ true. but you will be smarter and all if you build/re build the donor motor plus if its old jdm (ej20g/k) it will be a pain in the butt and you will do tons of research and will learn new things that way.
98 rs is the best yr to turbo dude..2.2t swap the block or a 2.5 sti block = gooooooood!!turbo kits are great.....until you break. early 98 RS dohc....dont turbo...go STI....tooo many issues and problems period, and only really designed for 165-170hp...adding more adds more time under the hood, .....when you could be getting laid. After 20yrs under hoods....getting laid is better than messing with semi hacked horsepower...go STI, go faster sooner get home and laid...more often, less work to get there.
