3SGE N,A Tuning

[scottedlin19]

Hi all,

Right been looking for an MR2 for a while; and I think I may have found the right one, but anyway Ive been thinking about tuning options as Im going to be keeping this one in my garage and fixing her up.

It will be the later NA engine running around 167bhp. (when new )

Ive had a search and tbh Im not very good at searching, but I did come across a PDF on tuning the 3SGE from an Australian source (road and track) was amazing to say the least, just looking for some clarification and pricings if possible.

Seen that I could possible run 300 Degree cams but would need a stand alone ecu, such as a motec unit, but which motec fits... 400 etc?

Could I learn how to map this myself it comes with software (I have computer and technical knowledge and plenty of time to learn)

They also say a performance panel filter is best, thoughts?

Also a Sports cat and a 4-2-1 system?

Lastly what about lightened flywheel and clutch?

Sorry lots of questions but Interested in doing alot of learning here

Thanks in advance.

Just buy a turbo, all versions are cheap enough especially the earlier cars, and certainly far cheaper than tuning a N/A mr2 with the things you'r after.

I should have posted no turbo answers.

I have a turbo car and I dont really like them, Im more interested in the learning and effort in a nice high revving NA.

So please no turbo answers.

BUT.. any supercharger kits out there..

I'm gonna say STOP! Do a search, do another search, do another one, try another one then try another search with something stupid. It works and this is something I want to see from a regular gen <3.

So please no turbo answers.

...do a search or do you want to know what it costs? I loved my gen 4, and it'll take allot of cash to get me something like it again.

I have im just trying to clear up a few things.....

[RST]

fill your profile out with your location please!

Sorry, wasn't mening to be abrupt but there's lots about tuning 3s engines, then there's owning one as well as the chassis they come with.

[scottedlin19]

I know and I have found bits, but wanted to clarify, as I said above and in my original post thats why I posted bits I have found... I just had some things I wanted to know about..

Its filled out now.

if you don't like turbo - why not search for a v6?

[Ren0W]

It will cost a lot of money, for very little gain.

If you want a nice revving NA, I'd say go for an 4AGE Blacktop something engine. Perhaps a different car as well indeed.

Otherwise V6 it.

They also say a performance panel filter is best, thoughts?
Also a Sports cat and a 4-2-1 system?
Lastly what about lightened flywheel and clutch?

A performance filter isn't gonna add bhp.
An exhaust line on a standard NA engine isn't gonna add much bhp. Maybe 4 hp or so.
Clutch and flywheel isn't gonna add power neither.

But, buying all those items, from a known brand, will set you back around €2000,- easy.

So, you do the math

after having a few go's in v6's

i love them!

way i hope to go 1 day.

If you're insistant on sticking to n/a tuning you've got to be looking at making it capable of mental revs. With that comes huge costs in getting every single component in the engine changed/modified to cope with the huge stresses that high revs create.
I can understand why you wouldn't want to go the turbo route, it's not a particularly great power delivery but not too convinced a highly strung n/a would be great to drive either.

To get an n/a (even a beams one) to 250ish Bhp must be over £5K maybe even heading towards £10K?
For that you are into well into 2GR territory and for £10K V8 territory. Whichever option you could go with gives over 325hp and a crapload of torque. Certainly makes it fun!

Hope that helps

hey man

looked into exactly what you are talking of years ago and I appreciate what your wanting. I, like you, am an NA man for many reasons. 3 engines later the truth is that all the thousands you spend on chasing figures just wont compare to the torque and easy progressive power of a v6.

my two pence is invest in a v6, spend your hard earned cash on suspension tyre and tranny mods and you will be rewarded with a car that is hard to beat up a drag strip but importantly, rapid up the back roads. you can have a turbo with 500bhp, but if you cant put the power down whats the point? useable power FTW!

i would love a v6 - like you turbo isnt for me. although fun, i prefer the instant response of NA engines.

wish someone down here in the south west had a v6 I could have a ride in

that's what I thought until I went for a ride in a 350whp td06 turbo mr2. then all v6 plans went out the window and there seems to be a turbo parked on my driveway
