Friends 5.0 vs. Turbo MR2
Me and my friend were pulling in a parking lot in his built 5.0( He just got it not to long ago, 3.73's, built bottom end w/ forged internals, trickflow intake, big TB, HEDMAN headers, P+P heads, puts ~325hp to wheels) and we see ~93 MR2 and can hear hte turbo on it. Well as we're pulling out of the parking lot he pulls out behind us and we get in the 2nd lane and he's in the 1st lane(This is on a 4 lane road). Well they both hit it and at first the 5.0 pulls a little but then the turbo spools on the MR2 and he walked us pretty bad. By ~55 he had 1.5 lengths on us. The thing was DAMN fast. The guy was cool though, we complimented each others car and he pulled a U turn right in the middle of hte highway. Funny ****.

Whatever... 325 to the wheels - most TF heads and E cam cars dont make that.

I agree those numbers seem high, but it depends on the heads. Trick Flow heads, ported, with a Trick Flow intake, throttle body, mass air and maybe an overbore could put well over 325 hp to the wheels!
Think about it he would have to go from 190 rwhp (about what stock 5.0s do) to 325 rwhp. That is 135 hp, and heads, intake, and an overbore or maybe stroker, I have a feeling 325 is about what it would make!!!
Anyway alot of those MR2s are turboed and nitroused, at least the ones near here, so maybe he sprayed! If not he definately had a larger Turbo on it, the Mustang should be well into the 12s with tires!

MR2 is just another way of saying TURBO CHARGED GO KART!!!!! I would not feel bad, those things are so light. And they are mid engine - rear wheel drive. I don't know why you all say it has a bigger turbo, there are other ways to up the boost, if he needs it.

True, but there are limits to what stock Turbos can handle, and in order to keep up with a mid 12 second car, and out run it like nothing I have a feeling it has a better than stock Turbo!

Yea i agree, i dont think a stock turbo could beat a modded 5.0 so bad unless he had a better than stock or he had some Nitrous under the hood to.

OK, I didnt feel like listing EVERYTHING so but since so many non believers, here goes. Block bored .030 over to 308. Forged internals, flat top pistons. Mass air conversion, ported/polished heads, larger TB, Trick flow intake, new intake tube/filter, 3.73's, larger injectors, hedman headers, H pipe to 2 chamber flows.

those mr2's are quick. My friend has a Celica GT-Four Alltrac (turbo, AWD... really rare car) with same engine as the MR2 : 3sGTE engine. These engines are VERy reliable and can handle 15 psi of boost ont he stock turbo etc.
they can get to around 250hp without major mods... but heck the car weighs like 2 800 lbs, mid engine .... they're nice cars.

Not unless he's running A LOT of compression. He's probably putting closer to 260 to the wheels.btw...an .030" overbore would give you 306 cubic inces.

Okay, now that he has the stock heads, I don't think he could do it. Wiith some aftermarket heads, and even just an FMS B-cam he could be pushing 300 to the wheeels, but with the stock E7s, I don't think he has 325! Flattops on a stock head would not be much different than stock compresion, and Nic is right, .030 is 306!

Well sorry, it's .040 over then. Anyways, look he lost hte race. Does everyone just pick apart everything everyone says in here?

OOPS... Forgot to add my fictional .600 lift solid roller too 
We really don't make it a point to pick stuff apart. However, there are a LOT of guys who come over here a make a bunch of bogus claims. If you went through the trouble to list an overbore and forged internals as mods, you surely wouldn't have forgotten the E cam. And I STILL doubt he's making that kind of power even with the cam.
325 RWHP in a Fox body would put you in the mid to low 12's on slicks. A lot of car for even a modded MR2 to handle.

Why would I come on here and lie about how bad my friend LOST. That makes absolutely no sense. And as for "major" mods, sorry I don't memorize everything my friends car has in it. I'll make a list next to my computer so I don't forget ANYTHING next time.

I could see him forgetting, when people ask about my car I always forget the 1.7 roller rockers! They are hidden in the motor and just slip my mind.
Even with the E-cam, he should only be in the 260-280 rwhp range, but still very capable of 12s!

I'm just going by what the guy who built his motor told me when I was talking to him. But his car is damned quick.

light weight you don´t really need all the same power to put down as the mustang
they are prolly close to 2400-2500 lbs
I know the spiders are around 2100 or so
and with some more boost or preferable a bigger turbo he should be able to pull something like that

Depending on weight, the mustang should be trapping 110-112 (if it were really the reported 325 rwhp). That said, he is not making 325rwhp with an E-cam and stock heads. He probably said 325 hp - about 275 rwhp - which is much more believable but still sounds exagerrated. Also, the pistons are most likely not flat top, and I'm not sure why anyone would choose to do that.
Has he had it on a dyno or does he just speculate? How about track numbers? I'm curious, because I'm thinking about getting another project mustang and trying to go fast on it with the stock combo and very little money invested. I know that home porting the stock heads can be as detrimental and it is helpful for some. What kind of gains can be made without a large amount of skill in porting?
I don't know much about MR2s, but if they can trap 110-112 without too much invested, I'd be surprised. I know anything can be made fast, but I haven't seen or heard much from the MR2 camp.

MR2s do indeed weigh around 2800lbs. The turbos range from 2700 for the most basic model to upwards of 3000lbs. They are NOT light cars. Toyota overdesigns their cars so they are VERY safe and extremely reliable, but unfortunately that tends to add a lot of weight. Up to 280rwhp is reasonably obtainable with the unopened stock turbo 3sgte, and with aftermarket turbos, there are some with over 500rwhp, heavily built up of course. A couple japanese guys have made over 750rwhp, which is extremely impressive considering its a little 2.0L I4. But power and drag racing is NOT what the MR2 excels at. They are pure handling cars. I've done track days at waterford hills back when my MR2 was bone stock NA (130hp, 140ft-lbs), and beaten Porsche 911s, BMW M3s, and C4 Vettes on race tires. That sounds absurd, but its completely true. The handling is simply incredible. Few cars can compete. And the braking, oh my ***. The '93(i think) - '95s got slightly larger brakes, and had the quickest stopping distances from 60mph of any production car EVER. 106ft. Thats 20 feet quicker than a McLaren F1, and 60 feet quicker than a honda civic SI.
Anyways, with a nice aftermarket turbo and some good mods, you can see 300-350rwhp without a problem. And that in a mid engined car(so it has awesome traction off the line), combined with 2800lbs, produces very impressive results. 13s are easy, 12s are not very difficult, 11s are possible, 10s have been achieved. I've even seen one japanese video with an MR2 that runs 9's. I dont know the specs on it though.
