Sr20 vs beams 3s turbo conversion

[pbmr2]

They are all bolt on mods imo. OK so the injectors need an ecu and mapping. but the motor doesn`t need to be opened.

330hp would be more reasonable as the stock turbo, injectors, IC, ecu etc can cope (at the ultimate limit). filter, fuel pump, exhaust and some boost control is all thats needed below that.

for chargecooling I`d use a barrel style core.

Still think it`s a mad direction to go for the SW20. A Subaru ej25 with an audi gearbox would be more powerful, lower CoG and just as much custom work. better balance left to right as well.
Plus the gearbox wouldn`t explode after every 3rd rapid getaway, taking £2k of internals with it. and prob the diff too.

I have a feeling we are kind of singing from the same sheet, just the internets is getting in the way.

Just looking for something I can use for day use and the odd track days so not looking for huge power maybe 300 - 500 area

Suggest you set your goal to a car with 300bhp at the crank.
That's about the limit of what you can do with the stock car, above that you're spending lots of money on forging things, larger turbos, injectors and inter/charge cooling and aftermarker ECUs, exhausts, manifolds, etc. It gets expensive pretty fast.

You can probably get to 300 with a few grand. Getting to 500 will be in excess of 10 grand.

FWIW, there isn't much on the road that will show a clean pair of heels to a 300bhp turbo.

Aside from that it's keeping the car healthy - bear in mind the age of these things and the preventative/restorative maintenance it's likely to need. That's not cheap.

Will do but if I can do most myself and save some money

Seen SR20s fitted into Altezzas before; they make for a good car but a lot complain about their reliability. Furthermore a lot seem to prefer the power delivery of the Beams even in turbocharged form.

Personally I'd love to see an SR20 or a Subaru EJ in an MR2 but I'd imagine the custom work required would make it prohibitively expensive.

All I will suggest is that if you start, see it all the way through. Being a member of a number of Car Forums has taught me one thing; only 10% finish the project, a lot spend a shedload on the parts then sell the project for a huge loss when out of cash or motivation.


P.S. If you need some advice about the beams, turbocharged or otherwise then drop me a message.

What about a k 20/24

As Gavsdavs has said, not much will keep up with a GTE with some BPU. To get bigger power gains you are looking at a hell of a lot more money or a different car / non Toyota stock setup. Your call.

I've looked down that route but I want something not many people have got I found a kit in us for k series on to e153 gearbox for $1500 and a turbo kit for $1000

K swapped MR2's are potent. They get a lot of hate, but it's an excellent engine - better than a 3S, as you'd expect considering the 3S is an evolution of a 1980's engine and the K was brand new in 2001. Takes a lot of abuse to kill a K20, and they take boost very well.

Personally I'd love to build a lightweight K24/K20 hybrid swapped hard top in the future. Daie Motors in Japan got a Rev5 NA down to just under 1000KG at race weight with the 3SGE - a K is a bit lighter. Something very appealing about a sub 1000KG SW20 with ~250whp rev happy NA (can be done with a hybrid K24). Not sure the E153 would be the best box for that though, really needs a close ratio 6 speed. Not a problem if you're putting a turbo on it.

Problem is at the moment it's pretty unknown in the UK, so the support isn't there like it is in the US. It's also not cheap - that conversion kit will cost you at least 1500GBP by time you've paid import duty, shipping, and VAT on top of that.

The engine and the people who pioneer the swap deserve huge amounts of respect. It's the fanbois that post "eleventybillionhorsepowers MR2 beats GTR" on every FB forum, every day that earn the hate. Largely being millenials, they can't seem to take any form of criticism without descending to accusing everyone of being a h8r.

*not everyone wants a honda powered toyota. They can't comprehend that thought.

[TonyleFrog]

Did someone say K20 and 'eleventybillionhorsepowers'?
Not sure about the billion, but eleventy - yup.
