[Mk2] [NA] 200bhp ??

[smithy69]

is 200 bhp a goal i could reach from a mk2 rev1 ??

[alanmr2turbo]

in a n/a? If so not really unless you pour £1k's in to it. Just put a tubby engine in and get more power and save thousands

[smithy69]

already got a 410bhp scooby mate i wanna keep this n/a std mr2 engine just seen on here the odd 194bhp claim so wondered if it could be done ?
cheers for reply tho bud

[alanmr2turbo]

well if you want to keep it a standard N/A then rip out the rev1 engine and find a low mileage rev3 engine that'll take you up from 154bhp to 175bhp as they came out of the factory. Get the passengerside loom with the engine.

Then all your chasing is the extra 20 odd bhp

[smithy69]

nice 1 mate i need to get it checked cus i had a rev 1 before and felt nice but this 1 is like xxxx off a shovel compaired to the old one ??

If you want to stay NA and are chasing power why not go beams? With some money poured into it I bet you could see way in excess of 200bhp...it would be expensive though!

[smithy69]

beams ??? sorry im hungover still lol

[ashley]

3S engine with vvti, was fitted with a single adjustable cam in some rev 5 MR2's (red top), and with dual adjustable cams in other toyotas (grey top)

Have a search on here under beams....

[smithy69]

cheers mate

if you want to achieve it on n/a base then yes a Beams engine is 200bhp stock, or you could go the v6 route , but otherwise pretty limited on a n/a ,

I don't see why it should be too hard to get 200BHP out of a non Beams 3SGE. You'd want to start with a Rev3+ motor (as stated above) for a 170-180bhp starting point. Getting the right cams to allow the engine to breath up towards 8krpm would be vital and some of the more aggresive Turbo profiles may do the trick. A bit of head work (probably OK on std valves) and finally some nice cheap motorbike ITBs on a custom inlet manifold. Run this lot with something like Megasquirt and you'd be into 200bhp territory surely. It may end up costing the same (or even more) than a Turbo conversion but if you want a screaming N/A for track work then I think it's well do-able

There is a company on Ebay that sells them

Seems reasonable, but I think the Caldina/Rav4 Beams is lower powered (187/178bhp according to wiki ) so not much over a Rev3+ 3SGE. Saying that it's probably just and ECU swap away from full power

ECU and inlet cam swap to get it up to red top spec.

Upgrading a naturally aspirated 3SGE to over 240bhp is way more expensive than a straight turbo swap. High compression pistons, independent throttle bodies, head work, exhaust manifold, engine management, cams, etc...

There are cheaper and / or better routes to more power but if 3SGE based n/a is what you want then you need to accept it's going to be expensive!

Which ecu swap?

[Rogue]

Which ecu swap?

Assuming you're referring to the BEAMS engine then you need the manual red top ECU for maximum power. Or just switch to a standalone.

[ashley]

If you're going for max power then stand alone ecu is a no brainer, you'll need to to take advantage of higher compression pistons, huge cams and a seriously increased redline

[4ndee]

Hmmm is there a 3sge stand alone ecu

[ashley]

Hmmm is there a 3sge stand alone ecu

Strange question....stand alone ECU's work with any engine you wire them up to and map them for don't they?

Take your pick, PFC, MoTeC, AEM, Syvecs, Link, etc, etc, etc

Apprently the previous owner of my two had an aftermarket ecu for a bit but I've never seen one before
