Mini Turbo Engine Recommendations

I've drafted the attached as a general guide to engine mods required to fit a turbo. It would answer a lot of newbie questions.

Generally I do not like a "one size fits all" solutions, but I feel that we need something.

Comments welcomed. But I don't need you to tell me of isolated examples where these rules are broken. That is always going to be the case and depends very much on the individual car/engine/driver.

My only comment would be for 100 bananas I would not bother with centre main strap or ARP bolts which you have said is ok and I guess just an asperation.

It is probably worth doing one for 1275 and 998 though. Same table for 998 just different power and probably a change to the drive train section.

Looks like a good start. Am sure a few people will be able to add to this. And a few disagreements may be aired.

If something is worth doing, it's worth doing half of.

Freaks!? Must be to do with some of us looking like BBC tv presenters and tea-pots.

This is a great idea. Being new to the turbo A-series there are a couple of questions that I would have and could be answered on your resource sheet.

1. Block :: A+ or Pre A+. Is Pre A+ okay to 100 bhp / 125 bhp, etc. Is there a target hp beyond which the A+ must be used?

2. For the recommended turbos specify the most common vehicles / years that these can be sourced from.

In my opinion either block should be fine. It it rumoured the pre-a+ were made of stronger stuff but I have no evidence other than rumour & hearsay.

However the A+ stuff was designed with strengthening ridges to make the block stiffer.

If something is worth doing, it's worth doing half of.

Could you use the GT1752 off the aero models on the 200bhp+ category? Is thsi the same as a Mitsi TD04?

I don't believe that they use the GT17 on the aero models.

the aero models do use a TD04 gav

A good idea Paul, only bit I would query are the H-section rods- the only person I know running these off the top of my head are Turbo Phil?

Looks good to me Paul.

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

That's a really good sheet Paul,

Obviously it shouldn't be cluttered up with too many options like "Benross elbow's" for example, but i think adding in intercoolers may be an idea as its a commonly asked question by newbies.

I like it, nice work.

superb paul

LOL

i was thinking along the lines of, upto 140hp RS turbo or equiv, and 140+ 2wd cossie or equiv.

nice!! Thank you!! very useful, hope to see more in future

Nothing special!

Very helpful to newbie such as myself and gives me an idea of how many pennies I need to raise for 200bhp......LOTS lol.

very nice, i would add a target compression ratio, as the more boost you run the lower the cr to help with having headgasket problems?

i was running 9psi on pretty much standard stuff with a cr of 9.4:1 and i was getting over 140bhp and 133lbps upto 6k rpm (never had headgasket go in the 6k miles it did)

was the standard metro turbo 9.2:1?

very useful and reassuring i have made some good choices. bar the 11 stud.

how about a cooling section? oil and water.

but great stuff!
