mk4 vvti head on 7mgte

[Green7mgte]

There are people pushing big numbers with the 7m

Would it be my choice?

Look at 7mpowa.

i belive reliability is a term not very specific, it relies on many variables motor condison, miles, oil changes, alot of other stuff. look at the bmw 2002 turbo i would consider that a unreliable motor becuase it has facts that show it would run like a champ if you fixed it every day, i have NEVER seen an unreliable toyota motor( some might be desighned in wierd ways yes) every toyota iv owned and worked on has lived to be about 250k miles at least. i know the 7mgte wasent built to be a full race motor so i dont expect it to be worry free at 1000hp but i bet the 2j wasent eather, any thing can be built to be reliable and fast for the correct fee( considering it isent compleat junk desighn to start whith)

( i would like a 2j in mine just because parts are much more common)

nothing wrong with a 7m but i t was only designed to push so much power and hold so much compression. there is just alot of things not designed to hold the rpms and power. lets start with the rods. ive seen alot of stretched rod bolts and bearing failures in stock 7m engines.
all im saying is why not start with an engine that was already designed to hold a higher power output.
agreed on the fact that inline engines are good. ive had many myself. but my 5mge and 7mge's that i have had use more fuel and make less power than most of the v8s ive had.
i just no longer see the point.

Look at 7mpowa.

ask what it cost them. compared to a v8 with a intake and carb. or ITB's

first off WHO in the right mind would build a 1000hp motor and use stock rods?, i belive the 7m and the 2j can easily hold 1000hp whith the right owner and builder but neither of them where purpose built for this kind of performanc.

my 5mge and 7mge's that i have had use more fuel and make less power than most of the v8s ive had.
i just no longer see the point.

of couasre the straigh 6 3000cc motor will need more gas and abit less power than an american v8. lets see im not an american expert( far from it) but isent even the smallest v8 at least 5000cc, when you start whith a high power big bore motor u dont really need much to get 1000hp, now look at the world of formula one they are running 3,000cc motors that push out well over 1000hp from this engine(could go even higher if they dident have restrictons on rpms and power), this can be done becuase they spin such high rpm's. any one can cram a ls2, super charge it and make 1000hp big whoop(never thought i would say that) there 6000'cc its not hard to make that much power if the motor is massive. it takes a real builder to make a reliable small displacment motor push as much as a bigger one.

not saying I would. just it is possible.. practical? your call.
IMHO I wouldn't take my 7m past 500 Bhp. granted I could even get it up that high reliably. (with my skills, mind you.) More of a reality for me would be around 350 on my 7m with minor overhauling.

your really far off. im talkin stockers being pushed slightly. i see it all the time... there is 3 turbo supras with bottom end problems for sale in my area.

there is 5 mk4 twin turbos all over 15k... but you also have to take into account the milage most mk3s have already undergone...
just talkin... not try to down anyones ideas dont get me wrong...

[pandrade]

lol here i was thinking u where saying some one went 1000hp whith factory rods, my bad

just talkin... not try to down anyones ideas dont get me wrong

no dont worry i love hearing diffrent peoples point of view about stuff like this, i enjoy the conversation and u always come out learning a thing or two
