hi, i am going to start a project thread soon but after some advice.

I am looking at doing a full space frame vts running 2 honda fireblade cbr1000rr engine's

this is going to be semi road legal, have a plan for my local police

has anybody on here done a full space frame any hints and tip's in this process, will start to upload pic's when i make a start.

Check out hybriduno's progress thread, although tbh if you need to ask, are you sure you could take on a project like this?

Mike_Roberts · 30th March 2013, 21:45

Unless you're a very good fabricator with a vast amount of tools, or have a lot of money to pay somebody to do it, you're probably biting off more than you can chew.

Semi road legal? It's either legal or it isn't?!

jay9119 · 30th March 2013, 21:55

yes it will be a good project. i am able to do most the fab work myself. i have full use of a mandril hydraulic bender, so the frame work wont be so bad im after advice on what sort of style to go i am after super light super fast, also i have a had a long think i have the 2 engine's with all wiring ect so having them rebuilt and a slight tune but i am unsure weather 2 have the 2 in the rear powering rear wheels or 1 front 1 rear and have a 4 wheel drive set up, also what suspension to use as i don't want to be running saxo suspension. i have a chap who is helping me build this and he is a pro at building bike engine'd powerd cars for autograss. so with all this aside . i need some answer's

1.whats best suspension setup for this type of car.
2.best brake's to use.
3.2 or 4 wheel drive.

Speak to z cars see what suspension they use, no one on here bar one person has a bike engined car, so what's good for their car won't be for yours. Weight distribution will be completely different

jay9119 · 30th March 2013, 22:13

will make an interesting thread then, i have the donor car so may start work asap

KamRacing · 30th March 2013, 22:22

If you are going to make a full space frame then you need the skill to create something stiff and light and with good suspension geometry to help get power down and get the car handling well. I'm guessing as you are asking the basic questions you are no engineer. If not I don't see the point as it will not turn ou well and no doubt will be worse than using the standard chassis. Best suspension is probably double wishbone all round. Best brakes - the lightest that will stop the car

Kebabman · 30th March 2013, 23:03

What was said above really. There is no point asking what sort of upgraded suspension will be best if you're effectively rebuilding the whole car. All the weight will be in different places and the structural integrity will be massively different. To get a car like that to work really well is a hell of a job. Have a look around the net for Andy Burton's peugeot cosworth and read up about how long it took him to get it working properly. He is an excellent engineer as well.

What are you planning on doing with the car when it's built?

Mike_Roberts · 31st March 2013, 02:07

There's loads of things to consider... Most of the bike engined autograss cars have a chain to a solid rear axle which is useless on anything other than grass. You can get diffs which turn a chain drive into a proper lsd with driveshafts but they aren't cheap at all!

Be prepared to spend ALOT of money lol. A blade engine alone will be £1500. I hope you're a very skilled fabricator with alot of spare cash lol.

however i wish you luck. Id love to see you pull it off

Misterk · 31st March 2013, 07:15

Wow, awesome idea and I hope you see it through..

Here is my mates car to give you some inspiration.

Fully space framed focus running a four wheel drive 2.6 twin turbo Nissan skyline engine

What your attempting is a massive task, the focus took years

jay9119 · 31st March 2013, 09:10

Massive task yes it is. But I am confident I have the skill to do it I have built a few cages that all have been ok. I used to work for power flow hence my tube bending skill's. I will be using a drive box from zcars so I have a diff so in turn will help put the power down, I brought both my engin's for 2k. From local bike brakers. As I want a very good handling chassis I asked about suspension and brakes to see what people's ideas are.

jay9119 · 31st March 2013, 09:12

Also I can not find hybriduno's thread anywhere

How do you plan on making it road legal?

jay9119 · 31st March 2013, 10:56

this is the thing im not it's going to be a track car and im going to use it to terrorise the local police force,

Ross^p · 31st March 2013, 11:32

I'm confused. You plan to use it on the road without it being road legal?

axsaxoman · 31st March 2013, 12:04

If making total space frame with fwd why make in a saxo?
If you do all that is needed then making a grp mould of a saxo shell to put on this frame will not be a problem to you ,
as for engine choice --why m/c engines they have bugger all torque compared to car engines --use 2 x honda civic typr r engines/geraboxs+suspension cross members +drive shafts +struts+brakes --half the job is done --they will relativly cheap --and you can drop a s/c on them ands get 400+ per engine and drive like a road car . or just suffer the 200 as std from each engine
there is no weay you can run twin engined car on the road and the conversion you are considering will need an SVA test anyway

Yates · 31st March 2013, 12:06

Spend all that money to then terrorize police, no doubt get it crushed ans you lose license?
