N/A's are more competitive cars in autocross. The 2nd gen MR2 dominates E-stock at the national level with ease, but the Turbo barely squeaks in the national standings.

 

For the money that you would have to spend to get a high mileage US Turbo model up to reliability, might as well just swap a low mileage JDM turbo engine in an n/a and pay the cheaper insurance.

 

i am doing the same thing once i get moved out, so keep us updated. id like to know your relative prices on future upgrades....

 

Hey i'll swap it for ya!I'll be done with mine tomorrow...been on it three days now...lmk

 

I would rather swap a n/a then paying high ass prices on a turbo model. Also insurance is a killer on a turbo car. Specially on a 2.

 

Just forget the swap and do like i did sale your n/a and buy u a turbo mr2 when said in down u may wish u did in the in when all is spent its gonna be little things that u will find and will bring your swap price way up...I have two mr2 and will sale u my black one for 6500 89k on it

 

the website is www.jdmaddiction.com.I can get his cell from a friend tommorow prolly. I think hes asking like 1700 for a 2nd gen motor-trans-ecu-wiring-harness ect.. The motors on his site might not be current, he might have a bunch of new stuff in.

 

You always have the option of nitrous too. That way you can keep your n/a, and just invest in a nice nitrous system, run anywhere from 50-75 hp, and that will get you very close to your 200hp mark. That way you would be looking at a 6-700 dollar 200hp versus a couple thousand dollar 200hp.

 

i have a little experience with nitrous. although i didnt install it myself, i have a 5177 NOS system on my 99' camaro SS.

how bad would it be to put some sort of system on the stock n/a mr2 motor??
how much hp can the 2.2l motor take?

i'm looking into superchargers for the SS and would have the bottle and lines ready for the mr. 2.

 

It wouldnt be "bad" at all if and when installed porperly with the correct precautions taken. Nitrous is simply an oxidizer...the only thing it does it allow more oxygen in your combustion chamber (nitrous is about 33% oxygen while atmospheric air is just a tad over 20..like 22 or 23 %)...which allows more fuel to be burned, hence the additional power. Its not some explosive gas (its not flammable at all) that just goes in your engine and blows up. Yes...more stress it put on the engine at that time, but its the same stress that would be added by ANY power adder, may it be forced induction or otherwise. And as long as you take the right precautions and know your limits you will be fine.

What i mean by that is make sure your fuel system is up to date and working well. This doesnt mean you need to run out and replace or upgrade anything, just make sure your fuel filter isnt clogged to hell...and so on. The same goes for you ignition. Basically what im saying is on a healthy motor, nitrous will be just fine. However, i would advise that you change your plugs to ones that are "colder". Also, you want to make sure your clutch is healthy. Drag launces, and nitrous runs can easily kill a worn out stock clutch.

Your engine can easily take a 50 shot...65 would most likely be fine, and moving up to a 75 shot i would just take my time and "double-make-sure" everything is doing well. You can take your time working your way up to there as nitrous kits come with a variety of jets (for 35/50/65/75 hp shots).

One kit i look at is the Nitrous Express Kit #20923 (Import EFI). Its a QUALITY nitrous kit with a well-designed nozzel. Its what i ran both times on my mr2 (i went through 2 kits at 2 diff times)

Basically nitrous can be a hugely friendly power adder to those educated in what it is and how to use it properly, not to mentioned its Unbeatable power-cost factor. Its really the best bang for the buck out there.
