Lizzord30 Posted March 31, 2004 Report Share Posted March 31, 2004 Magna 2nd gen head is from the magna from down under, The head has no jet valves, and not even the passages (can port intake side alot more plus stronger) The head flows about 30cfm more then a stock JV head about 20 more then a stock Non JV head and about 10 more then a manral aproxmently (intake side). Overall the head is better made, Only one problem is that it doesnt have the same colant passages on the intake surface as our intake (its the same on both sides not small on one). Other then that making it so we cant use on our intakes only magna intakes it will bolt on. Link to comment Share on other sites More sharing options...
Yanos Posted March 31, 2004 Author Report Share Posted March 31, 2004 Lizzord30- so from what you are saying, this head is really best suited for an MPI setup since you can use the magna intake? thanks for the info Link to comment Share on other sites More sharing options...
Lizzord30 Posted March 31, 2004 Report Share Posted March 31, 2004 Yea it you dont need as much modded on the magna intake no adapter plate needed Thats only like 20 bucks so nothing big still need the other mods to it. Link to comment Share on other sites More sharing options...
Big_J Posted April 2, 2004 Report Share Posted April 2, 2004 lizzord, do you know what years the GEN II would be from? i think the secend generation is the TN being 87-89. any other info is appreciated. thanks. -Jon Link to comment Share on other sites More sharing options...
SpooledupRacing Posted April 11, 2004 Report Share Posted April 11, 2004 so let me get this strait.. if I get a magna 2nd gen head all I will need changed over is the T-stat housing and the TB.. and the Magna head is actually better then the marnal (not by much but still) ALOS can u use the 284can roller rockers schneider HD valve springs and stock valves in the 2nd gen magna head?

Lizzord30 Posted April 11, 2004 Report Share Posted April 11, 2004 No the colant port in the back of the head is not the same as the conquest stock one. Would need a magna intake with no addapter but the rest still needs modding from tb and t-sat. So to run magna head you would have to have a magna MPI intake, and all thats needed to conver to mpi. Stock vavles and stuff should work tho. Link to comment Share on other sites More sharing options...
SpooledupRacing Posted April 11, 2004 Report Share Posted April 11, 2004 maybe I will go to the magna head then... I was pondering the idea since I know I can get one for cheeper then a marnal or CW.. so the only thing that dont have to be changed is the adapter plate.. cool.. I will find out if this guy can get me one SpooledupRacing Link to comment Share on other sites More sharing options...
Joel Posted April 12, 2004 Report Share Posted April 12, 2004 If you run a GenII Head on your starion and stock ECU... You better either take the turbo off or drill holes in the pistons or Kaboom. You can use it with MPI, as you can adjust the fuel and timing curves appropriately. Best suited for Race gas however. Compression goes WAY up, with flat tops likely up in the 9.0-9.5:1 range.

jinx Posted April 12, 2004 Report Share Posted April 12, 2004 sure u wanna go with the biggest ports on a turbo motor ? Mitsu went with smaller ports on later 4g63. So did toyota on their boosted 4ag. Runners on a normally aspirated 2jz are hoooooge compared to the 2jz-gte Link to comment Share on other sites More sharing options...
SpooledupRacing Posted April 12, 2004 Report Share Posted April 12, 2004 well I dont want to bump the compression at all so I will prolly just stick with a alabama head, CW or Marnal... but I will deff be hogging it out for sure with the cutsom header and MPI I got alot to do so this will be quite fine for me SpooledupRacing Link to comment Share on other sites More sharing options...
mrdodge01 Posted April 14, 2004 Report Share Posted April 14, 2004 So where can I get my hands on one of these heads anyway? I want one to go with my magna intake manifold... Link to comment Share on other sites More sharing options...
SpooledupRacing Posted April 14, 2004 Report Share Posted April 14, 2004 if u want a 2nd gen magna u have to get it form someone in AUS.. if u want u can just get a marnal, CW, stock or alabama head and have the intake converted either way I think the conversion is cheeper..

mrdodge01 Posted April 14, 2004 Report Share Posted April 14, 2004 I want a magna head for the greater flow capability... I'm pretty sure I'll outgrow a marnal head by the time everything is said and done.... and I don't want to buy twice. Anybody got some austrailian connections?

Joel Posted April 14, 2004 Report Share Posted April 14, 2004 If someone is from AUS that would like to sell me a 2nd gen magna head... I'm in the market. Joel Link to comment Share on other sites More sharing options...
mrb1 Posted April 21, 2004 Report Share Posted April 21, 2004 I may be able to help you guy's out. Depends if you want a junk yard head or a reconditioned head. This engine is called the Astron by Mitsubishi Australia. The heads (whole engine) were made in Australia not Japan. This engine started life in rear wheel drive form in a car called the Sigma. This is a rear wheel drive Galant, not sure if you had this car in the US. The Magna (FWD) replaced this car. Be advised this car was pretty common over here so supply should not be a problem however they are getting a bit old now. I can get multipoint manifolds as well but you would have to mod them.

Alspos Posted September 20, 2005 Report Share Posted September 20, 2005 Freight will be the killer. Magna heads are available but it depends on your intentions. The stuff listed below I got when I did this excercise for somebody a while ago. 1. Head around $200 from a wrecker2. check for cracks and flatness at a head place around $1203. Ship to USA. If less than 20kg then air mail would be around $A280. What's a head weigh?4. Port, polish, rebuild, intall rockers etc. or 1. Head around $200 from a wrecker2. Rebuild head or buy changeover head $ dunno, have to check but normally you give them your head and they give you a rebuilt one. Unsure of cost of purchasing one outright already built.3. Ship to USA. If less than 20kg then air mail would be around $A280http://www1.auspost.com.au/pac/4. stick on car and see what happens So there you go......

el_cachorro Posted September 20, 2005 Report Share Posted September 20, 2005 too much, you are right it all depends in my intentions, but going all that way to have in here after all that long trip, forget it> I will just get my self a Marnel Cylinder Head non jet valve with 3 angle valve job, that will be lot better, I Guess to avoid the Time just will be better choice the Marnel Head from Spain, using the ARP Head Bolts.

The genIIs are pretty much normal aren't they? or have you done more research since I was around last? Link to comment Share on other sites More sharing options...
saintseiya Posted October 5, 2005 Report Share Posted October 5, 2005 whats the deal with 2second and the 3third generation magna head, one is better than the other one whats the difference more compression or better flowing with better oil lubrication, will it work on stock TB injection starion system Link to comment Share on other sites More sharing options...
