Car preparation for the 1/4 mile
« Reply #15 on: August 26, 2004, 07:24:26 PM »
Buzznuts, or Glen,
I have an Fd which consistently runs 12.5 on cheap street tyres. The car is in stock trim inside, and i dont want to ruin a really nice car to get the times down.  But i want to get a quick car on the strip so i have recalled my old Gen 1 mk3,  it was an elford turbo but now has a TII gearbox, and a 1988 13b turbo engine, (the predecessor for the TII).  The steering is an egi rack and pinion but apart from that it is stock suspension and brakes.  I am going to strip it down a little to shed some weight but i want to keep it road legal.  

What can you recomend in relation to the rear end and also the engine.  I\'m not sure whether to port the FC engine or to try an RE or REW engine, as it has much bigger inlet system.  I have a Mits TD08 turbo 22b which i want to fit. (i believe its similar to a GReddy T88),  I dont care what it drives like on the road as long as i can drive it to the strip.

Any advice would be helpfull.  I would like to get in the tens but dont really want tub out the rear end.  Obviously slicks will be fitted at the strip.
Regards
tony

Hi Tony!

Anthony hasn\'t been around for a little while - I\'ll have a go.

Going the 1st gen. is a great idea, it is much lighter than the FD - and you will be able to run pretty good times with it (along with your engine combination).

In standard form, it should be able to get into the 12\'s without too much hassle (and around 1BAR of boost).

As for the rear end - it is quite a dilemma, I personally would spend a little bit more and have a 9 inch installed.  You have a great choice of ratios and it will be very difficult to break/axels are also strong etc..

Some guys out here run the Mitsubishi Hilux Diff\'s with pretty good success - but the ratios are limited.

The gearbox you are running will be quite strong, if it is in good condition you should be able to run some pretty good numbers.

As for the engine, I would stick with what you have got for now - is it running Microtech?  You can still run into problems like boost spike/creep pretty quickly if you are running a straight through exhaust (I use to run a 3inch on my Series 4 turbo engine, and had leaning out issues!).

You will probably need to run a larger injectors/bigger fuel pump (I\'m assuming it would have an aftermarket fuel pump in it of some sort?) - put a fuel pressure gauge on it also.

Also get a good tune into it.

Companies like http://www.pacperformance.com.au sell Fuel systems, which would be perfect for what you are doing.  Link here: http://www.pacperformance.com.au/content/lang__en/tabID__3931/Parts/Fuel_Systems.aspx  (makes it very cheap for you in £\'s).

Clutch maybe an issue also.

Get onto http://www.ausrotary.com and have a look to see what some of those guys have set-up (there are a number of Series I, II, III RX-7\'s with 13B turbo\'s).

I actually can\'t believe that there aren\'t more 1st gen\'s running on the strip there, compared to an FD they are a very cheap car to get running some serious numbers.
Thanks,

Hi glen, thanks for the info,
I will do the same mods on it that i have done to my FD as they are proven, ie, ported, (i may try to bridge if i can some templates), two fuel pumps, two regs, 850 prims and 1500 secns,  I just want to make sure that doing all the mods on the FC engine will not be ultimately restricted by the small throttle body and inlet runners. I dont think i can fit RE inlet manifolds on the FC engine. The REW enigne are quite a bit bigger and the RE bigger still.  If i keep the FC i will go micro tech unless i can get the FD sensors and TPS to fit and then i will go Apexi PFC as there are more people to tune it and i would like to learn to do it myself.  
Do you have to make a hole in the floor pan to fit the 9" diff or will it fit underneath? I want to have to tub the rear end out as elfords are quite rare and i dont want to make ireversable mods.
regards
tony
