Turbo help needed...
Turbo Mini Forums

Hi all,

Im running a standard turbo at the moment but I want to upgrade to somthing a bit better. Im running it at 21psi at the mo, but anything over that (I tryed 27) doesn't make any extra nannas, so just wondering what would be a good turbo. I don't want to spend anything over a grand really.

Also, Im using a minispeed turbo cam, which peeks at 5500rpm, would it be worth fitting somthing a bit hotter? Im not really botherd about drivability, just more bannanas the better.

Cheers, Kev

increase to a 1380 cc

phase 2 cam or 649

CR to 6.9: on a witches brew of tetraboost high dose 120 ron

with a larger ar housing

oh! a "well plumbed" large intercooler

As a cheap upgrade try a T3 with a larger exhaust housing, this will flow better at higher boost than the standard Metro unit.

Easiest thing of all - call TurboTechnics and tell them what you want.
21psi is way OTT on a stock T3

I agree with Ric, getting the power through the clutch would have to be addressed before going ahead withgetting more nanas.

Have you checked the inlet temp. differences with different amounts of boost?
Trying to squeeze that much air through the a small space is bound to heat it up a fair amount.

If you can cool the air temp down, its going to have the same effect as running more boost surely?

1/4mile in 13.2sec @ 111 terminal on 15psi

totally agree with ric

drivability is everything

21 psi is actually where the t3 40 trim makes most airflow 70 percent eff up to about 170 bhp then 65 percent up to about 200 , a step up may be the 50 trim or 45 trim from the escort rs ,which also has a larger a/r turbine that would suit higher boost and bhp . ,so for cheap power ,id go for a escort t3 ,and a cam that peaks around 7k ,with a good head and large intercooler .if yuo want higher boost than mid 20's id go for a gt 20 as pete suggests .prob a 2059.

Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM

Cheers boys...

It made 200 on baldwins rollers at 21psi, and that was it. Any ideas what the escort turbo is good for?

Im interested in the gt 20, will it fit straght onto the manifold and what power is it good for?

I spoke to TurboTechnics about a turbo, they said they can put bigger housings on my turbo and make it roller bearing for under a grand but better to ask around first what you boys think before I spent the mulay.

After the rr, the plenum was still cold, so the intercooler in working ok I think. When we tryed 27psi it started to worm up a bit but no pinking....

Im not bothered about drivability as it is not my every day car, and I want to race it when I get my licence.

Also, that does the phase2 cam peek at?

I would get those worms out of your intercooler

16V project underway

if you are looking for an all out race cam them i think the avonbar phase 3 might be worth a look. However if you do a search on this site i think john and mini williams had a few issues with it when they tried it.

phase 3 has a very narrow powerband, not a good acm for a road car

Ok, I mean low rpm drivability, my mistake. Im not botherd if its cack below about 4000 rpm. I didn't build my car for 1/4 mile more for some sprints/hillclimbs and extreem mightys, and only some fun 1/4 mile and road for now. My gearing is quite close, so I think a narrow power band would be ok for what I want the car for.

Thanx
