FMIC (will have to get an IK as well) should see you over 300bhp

Cheers guys,

so are we saying larger injectors, FMIC, IK and another map for 300bhp?

or will just the FMIC, IK give me that?

at the mo it hits boost/fuel cut at 1.2

you need a larger intercooler, bigger injectors or at least a Walbro pump and pressure reg to run any more boost. Also a post97 map sesnor to control boost above 1.2bar.

Go for the map at the same time imo as that will change your fuel cut and be able to run more boost

550cc are very popular and should run upto 400bhp (approx)

Scott.T@PolarPerformance

440's would be good for 320BHP, more with a pressure Reg.
550's OK for more, but for 350-400BHP you need to think about the longevity of the short engine and gearbox.

I have a set of 440's, phase 1 to fit '93 or '95 car. Email me for a pic - adbdba at gmail dot com. Yours for £90 posted.

And don't wast your money on a FMIC!

You don't need the lag!!!

Scott.T@PolarPerformance

FMIC are realy the only option for a Pre96.
Upgrading to a later TMIC is alot of hassle as very tight.
The Hyperflow TMIC is quite good, but also quite pricey.

I'll have a piccy too if you don't mind. dan.bohin@hotmail.co.uk

Cheers.

Dont mean to put anyone off a sale here, but please do be careful buying second hand injectors. I just bought a set and 3 out of the 4 needed be be changed! Would have worked out cheaper buying a new set in the end.

Next time I would demend having them checked cleaned and matched first BEFORE buying them. My set didnt match and cost around 100 quid to make up a matching set.

When you say "matched" does this mean getting each injector to sqray the same amount of fuel?

***Jonesy***

Yes. There was a 12% difference between my set, which andy forrest could not work with. So I needed Lateral Performance to 'make up' a matching set for me (by replacing 2 of the 4 injectors), then by the time they reached me one of them had a small crack in it so that needed replaced too! 3 injectors = 90 quid, plus the 140 I paid for the original 4 = 230 for a second hand set!

just be careful.

Tidgy

got 338bhp out of my 440's an not on max cycle, although they are phase 2 not phase 1, is there a difference between the two?
