Hello everyone, I'm new on this forum. First of all, I have to warn you that I'm a french-canadian so sorry if my english may look weird some time.

I'm starting a new project with my brother, we found a yamaha r1 98 engine in good shape but without the carbs, so I decided to convert it to fuel injection(I have a lot of experience tuning engines with megasquirt). I bought a megasquirt standalone computer and all the stuff I need, while gathering some info, I found out that these engine love forced induction, so I bought a turbo, td04 coming out of a wrx, the engine should make around 250 bhp @ 7 psi.

I bought plans for an st4 from badlandbuggy, on the pictures of complete st4 I saw, there's not much room between the engine and firewall so I was thinking about making the frame longer there for the turbo, also make the cockpit longer and taller because I'm 6'4". On the front, I don't know if I'll follow the plans or I'll fit some car spindle as I have already golf's spindle. For sure, I'll need good brakes, what do you think about the wilwood brakes?

The rearend worry me a lot, I don't think the st4 rearend will love 250 hp. I still don't have any idea what I should do with the rearend and still keep the cost not too high.

You have to know that I have access to a lathe and everything else.

If you're building the ST4 it is a veeeeeeeeeery good idea to widen and lengthen the cab, check out others ST4 projects and see what they did.

Heres the first one that comes to the top of my mind: http://www.minibuggy.net/forum/projects-progress/18493-new-build.html

Very well built ST4s.

Maybe it's possible to put the Edge PIRCV inside the ST4?

250 hp sound good:D

wilwood brakes are widely used in buggies and the feedback is very good.. I would suggest run brakes in all 4 corners!

No way u-joints will handle that amount of power.. you should use 930 cvs and since you have access to lathe you could make the center spool by yourself.. you can get the 930 rear suspension of the ar51 from ricks

use the search tool to find information in this forum.. there are tones of information in here
good luck :D

There's so much information on the website I don't know where to look at! and I don't know which threads would be useful for me. The 930 cv's would work pretty well but its kinda pricey, I had an idea 2 hours ago, what do you think about taking front cv's and spindle from a GM s10 4x4 with independant front suspension, cv's connect onto the differential with some kind of wheel with 8 bolts, those could be really easy to fab on a lathe. The problem with this would be the suspension travel, I don't think those cv will like 14 inch of travel.

Search f150 cv's on here, I seem to remember people using them and saying they have more angle than 930's
Here is a link to search I did....

Hummm megasquirt, it's not easy to set and tune, which version will you use?

Je connais quelques spécialiste du ms dans la région de st-hyacinthe si tu as besoin d'aide la dessus.

Bienvenue et tu iras te présenté s'il vous plaît :D

Well sorry for the french, if you wan't to know what we're talking about, haschel ask me which version of megasquirt I have and he told me that he knew someone in saint hyacinthe in quebec that could help me tune with megasquirt, I reply that the tuning part with megasquirt is not a problem as I have experience with this system an that I'm using ms1 extra and I tune with tunerstudio.

Also haschel, I forgot to told you that I'm from saguenay, so it's kinda far away from saint-hyacinthe

Here's the cv I was talking about
Pair NEW Chevy S10 CV Drive Axle Shafts 1982 1996 | eBay (http://r.ebay.com/BMXnxH)
I could use these with s10 hubs and brake, both balljoint are 4 bolts which could be really easy to bolt onto the A arms and I could keep the tie-rod end to adjust toe

Tell me what you think, ask if you have any questions.

The issue with them is the inner joint. While that tripod joint will plunge its only good for about 15* angle. Guy on here Voodoochicken used them in his build. Works fine just limit wheel travel to around 10"

I'll be working on a GSXR600 turbo over the winter. Looks like we might be close to each other. I'm just outside of Ottawa. I was thinking about going with MegaSquirt but it is a bit intimidating. Do you have access to a dyno or do you just tune by driving it around?

I live in saguenay which is a city in the north-east of quebec, about 12+ hours from ottawa. If you never used megasquirt here's my advices: the best way to megasquirt an engine is by using an engine that is still able to run without MS, first of all you should install all the sensors, rpm, O2 sensor, vaccumm, while the engine is running on it's stock carbs you can check if the megasquirt reads all sensors like it should. When everything is ok, you can try to plug megasquirt on the injectors and tune for fuel only(leave spark stock. Once the fuel is good, go for spark. Another thing, I pretty sure your cbr600 have 4 carbs, if you simply change them with 4 individual throttle body(itb), this setup will be very hard to tune, you'll have to use another type of algorithm(throttle positon sensor based vs usual manifold pressure)so you should build an intake manifold with individual throttle body.

I start by tuning while driving around, then fine tune on dyno. I use tunerstudio ( Welcome to EFI Analytics! | tunerstudio.com (http://www.tunerstudio.com/) ) go check it out, for 50$ it's got great features that make the tuning easier like auto-tune,once you have the engine started the hardest part is done, adjust the air/fuel ratio manually, more on the rich side then you enter your AFR targets on tunerstudio and the software will tune your fuel map while you drive until it reach the targets.


As for my cv's, I think I'll go for these cv, 10" of travel isn't that bad, they should be pretty tough for cheap.

Thanks for the advise. I'm starting with a 2002 GSXR600, which is already fuel injected. I've been going back and forth about whether to run piggy back systems or just go full stand alone (MegaSquirt).

Great! I'll keep you in mind once I get my project rolling.

Sorry for the thread hijack...
