Awesome, I'm gearing up to do this in a Nissan. How do you like the Haltech?

I like it a lot. There's plenty of support out there, so I was able to get it running without having setup engine management before.

Awesome swap! A word of caution - the more time I spend around longitudinal K-swapped cars, the more I hear of oil starvation issues. Of the 20-30 folks I've discussed swaps with once they get used on track, a majority have blown an engine up. Dry sump is not a cheap option, but an accusump would be worthwhile insurance. I'd suggest it if you don't have one yet. That, or really make sure your baffling and oil pan setup are done well. With all that said, killer swap, that's gonna be a blast!

Very interesting.. I'm thinking of a K24 in an S chassis. This is because of oil sloshing in longitudinal or the angle the engine sits at? I'll have to look into this. Thanks a lot

It's got a clockwise motion oil pan baffle. An accusump is a possibility in the future.

Dude you OWE that thing a good exhaust and a good intake. It'll sound insane when you hit VTEC in a lil British roadster

What intake sounds better than ITBs? They have pod filters for them. 3" exhaust, catted, two Magnaflow mufflers have it sounding good.

Well you said it was limited by the intake and exhaust, so I was mostly talking about the exhaust.

K swapped! what a perfect choice for an MGB to get rid of the dowdy BMC B series. They're such gorgeous cars let down by a very meh engine, and this engine is such a sexy engine. Wild, but not overkill. Also, even better with the ITBs! Awesome, just awesome. What's the difference in weight?

A couple of hundred pounds I think.

Ive been looking at MGBs to do this exact swap. What made you go with the Toyota trans?

Ive been looking at MG Bs all summer for this exact build. What transmission/rear end are you running?

Awesome. I went a different route. https://preview.redd.it/fhs6g9yrlu0g1.jpeg?width=4000&format=pjpg&auto=webp&s=d20f6d950b5454cd4ea031a56222a8b3944c9c26 It's a trash heap budget build, but it works. Well, not right now, because the stock fuel tank was so full of crap it keeps clogging fuel filters after an hour of running.

Intake and exhaust on the stock head with a turbo just looks like a nightmare. I don't like working on that side of the motor.

It wasn't actually as much of a pain in the ass as you might think. Just had to fab up a manifold that routed things forward, then the downpipe actually has loads of room to run down and back at a 45⁰ angle or so. It's 2.5" all the way. The TBs are from a snowmobile. I welded a trigger wheel to the crank pulley for crank signal and I'm using the distributor just as a cam signal. Using miata ignition and a speeduino. Turbo i got for $25 on FB market. It's from a mazdaspeed3. Biggest issue i have right now besides putting in a fuel cell is trying to get that damn british engine to stop leaking oil.

Impressive power to weight ratio. That thing must feel pretty quick.

IDK, they did add some Ford parts.

juwyro@reddit (OP)

Fords best parts are their axles and diffs though.

I mean the 8.8 is just a ford copy of the GM 12 bolt so of course it's good! LOL.

KacerRex@reddit

I was joking of course, the only better budget upgrade from an 8.8 would be a Ford 9". :) I fully approved of your choice.

Reply

juwyro@reddit (OP)

8.8 is already overkill for this. I'm a long way from needing a 9" and I'd be scared to drive the car at that point.

Reply

KacerRex@reddit

Nah, 8.8 is perfectly suited. The 94 in my flair is a GT with an 8.8 and you're already making more HP than my rat rod. As a bonus they are pretty easy to do maintenance on.

My other stock B has its engine out for clutch issues and to make the oil leaks minimal.

I’m planning on doing this to the Mgb I’m going to be burdened with inheriting one day.

That's the perfect engine for that size car. Do you have a writeup anywhere going over the issues you ran into combining MG Honday Toyota and Ford? Heck of a project

I have a [build thread](https://www.k20a.org/threads/k-swapped-mgb.226110/#replies) on K20.org and post on some MG FB groups. [Project_teaburner ](https://www.instagram.com/project_teaburner?igsh=eGJlaGp5Y3YxMjJv) on the gram.

Why the a3 head? 190whp is respectable for sure, but why not the a2 head?

Gonna need some better brakes to haul that thing back to the speed limit- how about suspension? It sounds awesome!

Reply

[-]

juwyro@reddit (OP)

It's rebuilt stock suspension with poly bushings, stock front brakes, and disc swapped years, and bigger master. I will be doing better pads now, these basic ones are a little lacking. I'm not doing track days or anything high speed, occasional autoX. Even on the back roads I keep my straight line speed well within reason where I'll have plenty of room to stop or a turn.

Holy crap that thing is Gona fly, probably tripled the horsepower just dropping it in. How did you adapt the trans/driveshaft?

McGregor motorsport bell housing for a Toyota trans to K and custom driveshaft.
