Drag FC?

[R32 Nik]

Right.. you\'ve probably been asked this before but here goes anyway.

We are looking at turning Sarah\'s FC into a drag car type effort..

What is the best way to get decent power from an egi?

Is it best to try and find a 20B to put in it? if so what sort of money are they (if you can find one).

Any other ideas???

Looking for inspiration guys as she is talking about scrapping it if it is not gunna be possible to drag it.

Please help.

scrapping it - WHYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY !

whats up with it

[R32 Nik]

It had soooo much welding done for the MOT last year that she thinks it wont go through this year......
Plus we need to free up some space for other things and We were thinking of dragging the Rex and getting rid of the supra, but if the Rex is not gunna be draggable then we may have to get rid, and she won\'t sell it, she\'d rather scrap it as she couldn\'t bear the thought of someone else owning HER car lol.

based on you scrapping it

can i claim in some very bizzare way that i sold you a charcoal filter and there for you could scrap it to me

[R32 Nik]

Will be that in mind mate lol:) but would rather drag it than scrap it. Just need to find out how to get decent times before we dicide.

if you are gonna use if purely for drag and NOT road use

remove all the interior ( leave seat in )

remove everything thing else that isnt bolted don

the yanks have a theory for every 100lbs you gain are 0.1 quicker on the strip ( dont quote figures )

get a lighter bonnet - or cut holes in yours

full decat and induction kit

then it depends on how much ££££££££££ you have

get the engine rebuilt with a streetport / bridge port

run NOS in it

the list goes one

it depends if you want a drag car or a road/drag car - but if its drag only - then you need ways to get it to the strip and im not sure if they need to be MOT\'d or not ? ( i doubt it to be honest )

for more power - speak to brett - he has an EGI at 200bhp - but thats running a bridge port

good luck - it may be a very good project you are starting

[MikeLMR]

yup as above weight loss is cheap and more power is expensive.

As for the engine, ditch the standard exhaust and fit a nice manifold and exhaust system. Then if your after serious power start modifying the engine internals.

[R32 Nik]

Thanks.. If I can figure out who Brett is I\'ll ask him lol

cheers guys.

Nooooo! Don\'t scrap it!

20b would be VERY Expensive to do what with engine cost, install ECU etc!

you would get a good performer with the following mods (in order of cost and serious performance potential IMHO

1) strip out cockpit
2) better breathing Induction/exhaust
3) lightweight bonnet (maybe carbon or FRP)
4) uprated ECU (I\'d go Microtech on an FC)
5) porting

once you have the ECU and the engine ported you can start playing with the rev limits! (Tim\'s Gen 1 ran over 11000rpm recently! )

The above would still be costly but it can be done in stages

Hi Nik,
All depending on the cash flow, but through experiance the most potential 13B engine would either the S4 13bt or the 13b-RE. The S4 engine will fit right in with no mods other than the wireing loom, but if you are tuning it then you won`t need much for a standalone ems.
The 13b-RE has the engine mounts near enough in the same position, and will need a little bit of jiggling to fit. This is a very potent engine when set up right with a big turbo and a half bridge/full bridge port.
Obviously all the chassis changes will need to be made, in order to keep everything nice and tight.

with it not having a turbo would it need a free flow exhaust or what ?  
Sorry not too sure with N/A motors.

what sort of money does 1/2 or full bridge porting cost?

thanks for the response so far guys, she is looking less likely to scrap it now (depending on costs of course lol)

[sadgoth]

because porting involes an engine strip and rebuild you are looking at similar prices to a rebuild, obviously you can reduce costs if you remove the engine yourself and take it to an engine builder. I had mine done by Tim at RX motors, not sure what he\'d charge if you removed the engine yourself but you are prob looking at sub £2k even if he does the removal and install.

cheers

on an NA engine having the largest diameter possible exhaust is not what you want, to get maximum effect you want to "tune" the lengths and diamteters of the exhaust to the engine so that it works with the engine to pull the exhaust gasses out of the exhaust port.  This also true of the inlet but with positive pressure waves.

[R32 Nik]

I thought thats what I had read somewhere.

Does any1 know if anywhere does exhausts for a n/a FC or is it a custom build job??

thanks guys

Nik

it\'ll be a case of try the usual suspects I think
