ever attemted?

[USPturbo89]

has no-one ever attemted to make hp with a ge? and im NOT tlkn bout spraying it at all!... im sayin even if u upgrade all the internals and electronics and plumbing that u culdnt make mor than 50hp? and if no-one has well ima try it for myself and c what i can come up with.. oh and without swapping engines...

 

[shaeff]

Many have attempted it. Few, if any have ever produced a dyno graph proving anything. Honestly, don't waste your time. You'll spend so much more money trying to squeeze every ounce of power out of it, that you could have a reliable, daily driven 400rwhp Turbo MKIII by the time you're done, maybe more...

 

[upgradedsupra]

Like he said ^^

 

[foreverpsycotic]

It has been attempted, and concidered a waste of money. Don't waste your time.
They also came turbo for a reason.

 

[USPturbo89]

well ima just work on it bit by bit.... and u dnt think even if i put cams, bore and stroke the block, port and pollish the head, and all i culdnt make at least 300-350 hp?

your to cheap to buy a GTe so u think getthing a Ge worked would be better? wtf are u thinking lol?

 

[dumbo]

just slap a turbo on it man. trust me.

i started NA. going turbo is like tearin the condom during sex.

 

[Setheroo]

Hey man, I have built a GE up before! You know how it turned out? Slow.

 

[85celicasupra]

start trying to find a company to make you a custom set of pistons....go for high compression, 12:1 should be good, stroke and bore it out like you said
get cams, adjustable cam gears,
new bigger valves, and valve springs.
some electronics for tuning,
plan on buying race fuel to run the high compression.

and still get beat by the guys with a turbo setup of the same cost.

 

[USPturbo89]

dude read my sig.... and thanx for the responses thats wat i wuz looking for... but im not looking to beat turbo supras... thats y i bought my n/a and my turbo... i have the best of both worlds when it comes to mkiii supras... lol just think high performance n/a auto, and tubo manual... lol thats wat im shooting for.. but n e ideas on what brand of parts from the tops of yalls minds?

 

[GotBoost?]

well ima try it for myself and c what i can come up with.. oh and without swapping engines...

This question comes up every once in a while. You plan on staying NA, right? Keeping in mind the 7mge displaces only 3 liters, I have a few questions: what is your projected compression ratio? What is your projected redline and your max piston speed? Rods and pistons? Pump or race gas? Engine management? What are your plans for the valve train? Valve spring rates? Oversize valves? Track only car? First comparison that comes to mind is the BMW 4L found on the 540i. It made 290 hp with 4. BMW had a team of engineers develope this motor. So I must ask, what's your machining, parts and tuning budget?

 

[juhanis]

i'd say, 300shot of direct port nitrous. that will wake her up... for about 30seconds.

 

[IJ.]

ohhhh my..... :nono:

 

[Keros]

I think the 7M-GE N/A motor would be a great platform, depending on how you value your money.

If you value it in such a manner that you use 100 dollar bills to light your fire place, then it's a great engine platform.

If you prefer a good rate of return on your dollars spent... just put a turbo on it.

 

[USPturbo89]

hey guys....? i already have a turbo.... and its standard... my n/a is auto... and imo nitrous oxide is for whimps... but n e who ima build it slowly, and at the same time ima build my turbo a little quicker... but appreciate the responses...

 

[toy fanatic78]

It's a different "kind" of power,completely different power band.I still believe a properly built,reliable 400+rwhp turbo motor is still gonna cost you out your ass,even more so if the car was originally na and you upgrade the drivetrain to suit (r-154 and maybe rear end.)

 

[shaeff]

I disagree ^ A 400rwhp Supra can be built reliably on a budget. You save lots and lots of money doing all the work yourself. Just a stock rebuild is plenty for 400rwhp, and a stock rebuild is inexpensive.

The differential will be fine, the w58 will last a while if you keep the hard launches to a minimum.

Like everyone else said bro, building up an N/A is pointless and a total waste of money. If you want a powerful N/A, swap in a 6 liter motor. That's about the only way to get any kind of power out of an N/A is with displacement. Remember what a turbo does, it forces more air into the cylinders than is naturally possible. I run 13.1 PSi (14.7 is the natural pressure, so I'm forcing almost double the air naturally possible into my cylinders) on my 2.5L 1J an I've driven with no boost at WOT (piping clamp broke) and I gotta tell you, with no boost my Supra was slow as hell compared to when I'm boosting. It felt like I was driving my Geo. Don't waste your time and money bro, put a turbo on it. If you hate lag like me, get a twin-turbo so the lag is almost non-existant.

I meant in comparison to a moderate na,and on the idea of starting with an na chassis and going gte.I really don't see any reason an na can't survive on a stock rebuild bottom end,(knowing they will never see the kind of power that the turbo cars push on a stock bottom end,without issues)saving $ by doing the majority of the work yourself.Highest expense would be high comp. pistons,if you choose to up the CR.
Now starting with a car that came turbo is an different story,and 400 rwhp would be "cheap" to obtain,but,if you have to buy all the turbo stuff,it will add up a lot quicker(gte block,ecu,harness,IC & piping, turbo, manifolds)And assuming nothing needs rebuilt(ie.engine internals.)
I would be extremely happy with anywhere near 250 rwhp in my na with the cost of a rebuilt motor.Already have every BPU available,and not that much into the parts,just caught real good deals on everything.I'm under $600 and so far have gotbx header,HKS MHG,ported head & intake,rc bored over TB,full toyota gasket kit,new rod and main bearings,K&N fipk,2 1/2" exhaust w/high flow cat and SS supertrapp muffler.Looking at ~1100 for the pistons/rings,and a set of cams,Machine work is free as I painted a friends '68 camaro for cheap in trade for that.Not gonna get everything to go turbo,w/a fresh rebuilt motor for less than the ~$1700 I'll invest w/o cutting corners and sacrificing reliability.
Also not looking for nothing real powerful,just a reliable,fun highway cruiser.

Wouldn't consider it a total waste of money,just depends on what you are looking to get out of it.If your wanting even 300 hp,then yeah,just forget about it,your wasting your money.
I personally wouldn't hesitate to put $2500 into a car that I like,turbo or not to fully rebuild the motor.My na will be built as far as it can go and retain streetability(pump gas,decent idle)for less than $2000 and I will be more than happy with it(ran high 14's before).I was happy with it before I tore it down,did that more for cosmetic and chassis issues than engine.But ,like I said ,I don't expect a bunch of power either.
