Supercharged K20 Engine Builder

[Ronnie]

Does anybody know of a reputable K20 builder that can put together a good engine for this project? If I bite into this project, I know I'll spend less in the long run than piecing things together. I might as well get a good motor off the bat to start things off.

[Karlo]

How much do you want to spend?

How much do you want to spend?

===============================
Karlo:

Want to spend? of Course ($0.00)

Willing to spend for the right engine?

K20 w/ Turbo, 400 whp.

$5-$7k? or more, I just don't know what to expect to pay. However, maybe this would help:

400 whp
Pump Gas
Very Dependable
Drop in and bolt up to SL-R Chassis
6 Speed that will handle the Power and be very Dependable

Would like pricing and internal specs for same Engine/Trans as above but at:

250 WHP
300 WHP
350 WHP
400 WHP
450 WHP
500 WHP

I would guess that this would be 2 maybe 3 Engines with varying amounts of boost.

One engine with stock bottom end (no Turbo) > 250 whp
One Engine with Stock Bottom End (With Turbo) 250-400 whp
One Engine with Forged Bottom End (With Turbo) 400-500 whp

A Boost Controller/Regulator or hp regulator would be preferable with any Turbo Set Up so the Car Could be Dialed in to the Track or Street for ease of Driving. Too Much of a good thing can wreck a good time. Plus, I would want to practice driving skills with varying amounts of power.

Is this enough to get some names of people who could produce a "Turn Key", Engine for the SL-R?

Thanks,

Ty

Ronnie,
I would recommend doing this project in stages, and to get the car running with the stock engine first. This should be easier if you have any problems getting it running as the variables are less. Taking a normally NA engine, turbo-ing it, and then installing it in a completely new car yourself could prove to be a headache. I would drive the car for about 1 year to work out all the kinks, then if running great, proceed to add power.

You may even find that you don't need the extra power of FI with a K20. IMO, you are choosing the wrong engine if you want turbo power (4G63 or SRT-4). You can get close to 300whp from a NA built K24 with cams, pistons, and ITBs.

400 whp. = $15k-$20k with gearbox to match.

a used K20a Engine and Trans is $6k

There not enough people who want a Turn Key setup. People have different engines they like. Honda is one of many that can get to 200+ with easy mods.

I agree with wgknestrick on the progression of engine mods and build!!

[cheapracer]

250 WHP .. Bit of extra overtime next year.

300 WHP .. OT + Throw in some Saturday mornings for the Boss

350 WHP .. Pricey, no new dress for the wife

400 WHP .. Expensive

450 WHP .. 'effin Expensive

500 WHP .. Gulp :nervous:

I feel a bit uncomfortable seeing that Karlo seems to be marketing some Honda engines but as I pointed out elsewhere and now wgknestrick mentions the 4G63, look for other Jap brands for this HP. I honestly don't know why Atom use them for the 300 since they aren't forced induction engines in the first place. Your just adding big expense to an already very expensive engine. If you really want 500hp go for the 3.8 V6 with turbo or blower - you'll get there with a minimum of fuss and bucks with big bottom end torque to boot. You've seen the engine weights and remember with a 3.8 you can delete the need for an intercooler and it's plumbing (run water/alcohol with boost instead), you don't really need 600hp!

[cheapracer]

Oh hang on, you mean WHP, at the wheels - adjust my list and move all the right hand side comments up one and add double gulp to 500 WHP or merely sell your house.

Go haunt some Pontiac Fiero forums and find out what they do with their beasts.

[wgknestrick]

500WHP is nothing that should ever be put in one of these cars. Get back to earth. 300whp is an insanely fast car when weighing less than 1500lbs. My STI has 400whp and is more than a handful to 99% of drivers and it weighs almost 3Xs as much.

Even if you wanted 500whp it would be nothing difficult or expensive with a 4G63, but you may ultimately regret having it. Like I said, get a stock engine in first, then see where you need to go from there. Do not overlook the reliability of a hammer. You don't need to corner yourself into a fussy engine with this car for it to be fast. There really is no reason to put anything but a stock engine in the back of these things.

Point taken. Thanks. I got caught up in the power thing when I ordered my Superformance cobra. I don't even drive that enough to warrent having it. I wouldn't sell it though. Your points hit the nail on the head.

[Gage]

Listen.. Over 300whp in a car like the SL-R is beyond fast. It is stupid fast.

You just don't have to make as much power in car's that weigh so little.

I'm a big fan of Overkill and 300whp is my goal. I speak from personal experience in a high horsepower Ariel Atom.

Any K series Honda motor with a >>>> MILD <<<<< application of boost from a Rotrex supercharger will be more than you can effectively utilize in almost any application.

And I'm all for trying the other motors mentioned as well.

Your no fun.

I am quite looking forward to driving my 500kg's + 120hp :-)

Thanks for the help.

Sounds like a N/A Built K24 with 9:1 Compression would give decent power and be ready for a turbo in time, Right?

Ty

Why does it seem that the K24 engines are not as popular as the K20 Engines?

=======================
I was really wanting to get a feel what is possible and at what price point. An aquaintence of mine has a Ultima with a Twin Turboed LS-7. It makes over 1100 hp. However, he also has a controller inside where he can adjust the boost to the driving conditions. He drives it everywhere and when he wants to Enter the Siver State Challenge, he just changes the boost level.

Seems like a good way to balance what could other wise be a nightmare on wheels.

Hope this helps,

What is a, "Hammer"?
Who would you have build you a 4G63t that could make big dependable power, "Governed by a Boost Regulator"?

Do you have anyone in mind for your 300whp engine? If so, please send me a PM or email. I really would like a great Bang for the buck, but also have reliability.

I'm a bit confused by your post's Mate, you want bang for buck but you want to scratch build a 2.4 non turbo engine into a turbo/blower for only 300hp?

A 4G63T will turn out 300hp using the stock standard motor and just bolting on a slightly bigger turbo. There are quite a number of websites dedicated to 4G63/4Ts, builds, hot up tips for standard etc, a very popular motor for very good reasons - worth the reading.

This may be of interest...

I sincerly hope you aren't sticking with the Honda just because of the chassis engine mounts, its only steel and a few hours work. I can't talk for Fran but if you rocked up with a Mitsu engine (or other "popular" engine) in hand and asked me to whip up some mounts for you I would be glad to as this process gives me another engine option for my clients. I would do it for free if I considered there was a market for the engine, a one-off I would charge you for.

============================
Cheapracer:

Thank you for your post.

I can see how things would seem confusing. Since I know certain people have affinities for certain engines, it makes me want to ask those specific people the same questions, then I can see what fits me best by the people who REALLY have a lot of experiance with their FAVORITES.

I am so clueless about these smaller engines, that it is rediculous. On one hand it seems like all of them can do 300+ whp, but knowing who can do it the most effectively, or easyest with longevity, is the real 64000 question.

I'll start hitting these websites you recommend and see what I find. I know your thoughts have merit, it's just me wading through all the choices that has me kind of bogged down.

On the other hand, I am learning a ton by some very generous people who are will to share their knowledge. I really do apppreciate it.

More later,

Thanks Again,

Ty

[cheapracer]

Let me make it clear that I have been around the stinking things for so long I hate them all in that love/hate thingy way. I have no affinities for any of them but they serve a purpose.

Heres your Honda info..
400 whp. = $15k-$20k with gearbox to match.
a used K20a Engine and Trans is $6k

I would price a complete running 4G63T and wouldn't be suprised if you are looking at $1500 - $2000 for a ready to go, good condition runner to get you up and running and if the expected 250+hp from that isn't enough all you will have to do is buy a new Turbo later - same for the Toyota and Nissan and they are all usually good for 200,000+kms. I once again point out that these are engines built standard to withstand up to around 350hp. Almost no manufacturer builds a standard engine with a hp rating of more than about 70% of what it can actually stand. I don't know much about the Dodge but at 2.4 already I imagine that just a mesely 10 or so PSI would see 300hp.

The choice is so clear and maybe that in itself is the problem, it is human nature sometimes to not accept that sometimes things really are that simple.

Sorry if I'm wrong about the prices, thats Oz market price but also in Oz dollars.

I had a 2006 Mitsubishi Lancer Evolution RS with the 4g63 Turbo and all wheel drive making about 280 wheel horsepower. I dearly loved that car.
A 4G63 would be a fantastic engine in an SLR IMO.

Oh, Ever heard of Vishnu Performance? I installed a package of upgrade parts from them and then had my Evo dyno tuned. I asked for a conservative tune with good gas mileage. That meant only 280 to the wheels. But, I was very content.

Is the 4G63t a "EVO', Engine? What about the 4G64t? Can you rank the best Mitsibishi Engines down to the worst, and also give the alternate names for them, if they exist?

I have been reading up on these engines and as you already pointed out, they are relatively inexpensive. I really want to know exactly which ones are which.

Any short explaination would be very appreciated.

4G64 is a 2.4 litre, and the 4G63 is the 2.0 variant. You guys are wierd you all have mentioned nothing of the Honda B-series of engines, I mean they range in displacement of 1.6-2.0, and vary in power from as little as 160 all the way to 200, and the beatiful thing is you can interswap parts between them to create an awesome engine, and I'm also including pistons. I have been an avid honda enthusiast, and see the k-series as too expensive of an alternative, and also lets not forget the extensive list of mods available for the engines and transmissions in the aftermarket.

My honest to god opinion you can build a 400 hp honda engine package for less than 5 grande and yes that includes tranny and supporting mods with ecu and tune.

Point well taken.

5G's for 400 hp & and Tranny is a great bang for the buck.

What formula would you use to get the package to that point where it would still be dependable. (If possible)

Thanks,

Ty
