Well guys iv been thinking of addin a little pep to the Wagacy. Right now my current 2.2 sounds a little like death, and its all coming from the bottom end. with max doin a turbo swap, im thinking about pickin up his MY98 2.5 block and putting some 2.2 heads on it. i know this set up can be run no problem on the stock ecu with premo in the tank so thats most of the attraction to it. Im thinkin this will be a pretty nice little budget upgrade. What do you think? Also any of you guys that know about this set up, i have a set of 93 dual port heads and of course my 97 single ports, im still trying to decide which way to go, i know if i go dual port i can get a sweet header. just not sure what to make of the hydrolic valve lash adjuster stuff and if it really makes any differance, anybody know were i can find some specs on both of them, (cams, valve size, things of that nature), i know it can be done either way, and actually going with the dual ports will help me save some down time. Im assuming my 97 IM will bolt up to the 93 Heads no problem? well anyway, let me know what your think, or help if u can help, thanks! ~Kyle
yes it would be a torque MONSTER, do it, use STI head gaskets i PN# 11044aa642 your best bet would be to use the heads you have now, older heads flow worse even though they have two ports (they have smaller valves) basicly put your heads on the 2.5 and use your existing intake
as AWDL said, the single port heads do have bigger valves. but, as you mentioned, there are way more header options for dual-port heads...
Do it! It'd be sweet, then it would truely be the Wagacy of Doom. Hopefully I'll have a short block for you shortly
Just use Pete's gargae to fab your own headers. Single ports would be easy to do. Or you could prob go to Badd Brad's. Either way, what the hell. If you do gothrough with it, I'm taking my old shortblock back
is the STI gasket a thick one? from my research i was basicly under the impression that i should use the phase 1 DOHC thick head gasket...
^no its still right above 11 with the thicks from my understanding. also eveybody says that most of the gain is from the 2.5 block not really the higher compression.
Or at my newly accquired place, with my new MIG. We all told pete once I got a garage we were never talking to him again...and he seems to think were kidding. Would the 2.5 ECU run this better?
I have taken a liking to the dual port heads. the single ports do have larger valves but are stll only single port. IMO if your going frankmotor you shoudl use the dual port heads and just through in some oversiexd valves and walla! also you might look into some cob spicy cams, TWE stg 2 cams, or just some delta regrinds for more power/tq. EDIT: Also i wouldnt be surprised by a land slide of votes. you dd ask if you should mod a car on a car forum lol.
^ haha yea, dont got crazy martin, im not even looking to rebuild anything, no oversized valves no delta regrinds, atleast not right away. the most i will probably do is try to port match the exhaust side.
ovresized valves would be relatively cheap to do, and yeild good results on the "awesome" dual port heads. also IIRC a delta regrind only runs like $150 or so.
^well yah, you need to widen the openings to accomadate larger valves. pretty sure that it wouldnt be absurdly expenive to get it done though.
Head/portwork is one of the more expensive parts of building a motor. I wouldn't be surprised if it would be 10-15hrs for such a job. It's not just regrinding the valve seats, but blending everything so the larger valves are actually worth your while.
