say i bought an FRST but didnt wanna go T3...........

what is the peak sorta power and torque you could expect using a T2 (be it stage 3?)

i mean the car would be running low comp bottom end, uprated injectors, intercooler, head and uprated cam ect but would want to keep the T2 to keep the car tractable on the road.

im guessing at 175bhp while keeping the car reliable?

whats your thoughts?

175bhp is good power for a FRST and will still be a handfull. Without a LSD i would say thats enough power. I have 140bhp @ wheels and i have to take care especially on wet roads, understeer and wheel spin is all i get, as we all know the T2 comes on very low down the revs.
As i have mentioned the LSD, remember your gearbox wont like lots of power, mine gave up.........i was lucky i caught it just in time.

But once your engine has the capapbility to produce more, you will be tempted to keep pushing it.

id be more than happy with 175bhp!

in fact in my opinion this is around the optimum usable (day to day) power for an FRST.....

will an FRST box not take around 200bhp tho?

Geooooooooooooooooooff?

How much torque is your FRST pushing out and where on the rev range does the boost start to build up? When does it start to really move?

Ask anyone who's gone from T2 to T3 and they'll tell you that they'd never go back to a T2 ever again.

The spec you list was pretty much what Paul R was running before he got his Zetec. T2 running 16psi, chargecooler, cam etc.

He couldn't out-accelerate me and mine was just chipped with the T3 (10psi).

You can't run more than around 8psi on a std T2 without it cracking the housing, and a hybrid will cost £700+, for which you could do the T3 conversion twice over and still have change for an intercooler.

Id forget about low-comp and bigger injectors and go T3 with a suitable cam, and a GRS intercooler. Run 10-12psi then spend the rest of your budget on rose-jointed lower arms and front and rear strut braces.

ok ade thanks mate, ill look into that

"8psi"......erm, i think they will easily push 12 psi without too much hassle, as long as your oil is changed regualrly.
Yes i know mine is a freak turbo and happily hitting 15psi, but thats because of the IrnBru i put in my oil

Voorhas : Thats one thing i dont have, i should get myself a torque graph next time i have my car on the rollers. Anyway, my car still has a std T2 so the power comes on very low down and with the help of my cam it keeps going, but as usual the T2 runs out of puff at about 5k revs. So no point hitting the redline. My peak power is 139.8bhp @ just over 5000 revs.

I TOTALLY agree with Ade here..

Myself and him argued over this point, because i was sure i would never want or need a T3 conversion.. BUT after going through abiout 4 or 5 hybrid T2's under warranty etc, i decided to take the plunge..

OMG does the T3 make a difference, i ran a standard T3 for a while, and wanted more so got a stage 2 T3.. Main difference is the top end of rev range, it never runs out of puff, i pulls right to the line, where as i could feel the T2 running out and being overworked..

Plus the T2 doesnt come in stages it it hybrid or not, the T3 has a few difference stages to suit your needs...

Also the T2 is known to be a crap turbo in the FRST once modified, it is very very prone to cracking and seals going because it is not strong enough..

This is the first time I've read this on the forum, I've seen figures of around the 14-16psi mark.

My mates broke his ERST and still has most of the stuff I'd need for the converstion, my opnly dilema is I've had a brand new turbo only 6months ago. Is it worth swapping and facing the bill for a new T3 (how much?)

I had the bottom end low-comp'd when the piston broke, but I thought that I'd need new injectors and stuff to get more power out?

Thanks

My mates frst is running a T2 and has hit 178BHP on the rollers.. a few engine bits done, but only standard bottom end etc.

I went T3 and the power is sooo much different and as Ian and Ade said above, you can feel the T2 running out of steam.

[IanRST]

Who does the whole T3 conversion near the Kent area or London i am not that mechanicly minded so i would need the lot being done so where and how much?

[AndyBlackFRST]

The T3 conversion is very easy to do if you have all the parts there, the only bit that needs sorting, is the exhaust joining..

SCC can do this work for you if you want it local (St Albans)

[DorsetZS]

Are you willing to say how much you paid for yours Andy, and whats parts are involved, reconed or new ?

[Ian C70T5]

I used all parts of my missus ERST

Bottom Intercooler to turbo Hose
T3 Turbo/Manifold
Oil Feed Pipe
Oil Return hose
Oil Return Boss for Block
Modified Down pipe from T2 turbo and T3 pipe
ERST Top Water Hose

Total Cost to me was about 67p for the Exhasut Manifold Gasket

I then upgraded to Hybrid Stage 2
