Right well I'm going to go down the road of a twin turbo setup because its easier than a single. What sort of sizes of turbo do you recon I could go for? T3 maybe?
I don't want to go too big and go unreliable?
Just brainstorming at the minute, gathering info and parts for when I start it.
Twin turbo setup?
Moderator: martauto
Have a had a look at the (Norwegian?) E30 M3 S62 TT project, pictures should be found somewhere around the 'net. It had very proper setup and the turbos weren't so big, fitted in the engine bay quite well.
As for the sizing, I don't know. Watercooled units could help with the temperatures (which will be a problem in any case).
Good luck and shoot lots of pictures!

What is your power goal? without that sort of information it´s impossible to reccomend any turbo size.
Thanks for that jonsku I shall have a read up on that one when I get in
The power goal is kinda a rough guess at 400bhp but I don't want to start changing pistons ect so only want to run low boost for now if that makes sense.
I'm very new to force induction so I'm all ears on free information gunni

well iv found abit of info on that project of his including the companies Facebook page boii, http://www.facebook.com/pages/PeeBee-Mo ... 3948810438
that E30 is amazing but still isnt finished from 2012
they are alittle closed book when it comes to sharing information too.
the turbos they have on there are GT35 which are quite big really

for only an additional 100hp I don´t think turboing is worth the effort and cost.
Two GT35´s are for sure way to big, But given that you have two 2liter engines, two T28R´s from a SR20DET would be a nice setup I would think, reaching 600hp+ without to much trouble turbo wise.
Not sure on the engine itself in terms of what is needed, but two thicker MLS gaskets and some ARP studs wouldn´t be a bad idea.

well lets just face it i think i was batting abit low with 400 but 600hp would be nice.
i was thinking of going with the T28s as they are almost off the shelf and wouldnt have much lag, head gasket wise how do i work out what compression i would need gunni?
i wouldnt mind starting to gather parts now to start it this winter really.

I would imagine,
Assuming the following I just found online quickly...
M62B44
Bore is 92mm
Sroke 82.7mm
CR of 10:1
Stock HG of 1.74mm
Flat-top pistons
Would indicate that theres a combustion chamber of just under 50cc plus the gasket which would mean a swap to a 3mm gasket would give a CR of approx 9:1.
Thats more in keeping with the 8.5:1 that stock SR20's run and if it were my car i would suggest that the very best turbo to run would be the T25g from the 180sx redtop engines as these are quicker spooling than the normal UK version T28 and are easily available as people upgrade.
They would give you an easy 250-270bhp per bank with almost no lag and they would match the slightly slower revving nature of the v8 well as they would choke from displacement above 6000rpms at a guess anyway on stock housings.
I dont think you can get away with much more before having to spend out large sums for pistons and other items, although I have almost no knowledge of the M62 engine and its robustness, I think they have forged rods buts thats about all i know. Certainly you would be looking at 1.4bar or more on the T25 and you'd need studs and some decent intercooling to ensure that you dont get detonation on a massive scale, probably meths as well for full power runs and maybe keep a low power and high power setup available on your boost controller depending on your ecu choices.
Interesting ideas - making me think about doing it to my convertible project !!

Well that was a interesting read matey and certainly good for thought, I just need to get a set of head gaskets at 3mm or a layered type, things like that just arnt readily available in the uk which is abit of a arse.
I really can't wait to start by pulling the M60 back out and constructing the mammoth task of the manifolds and getting the turbos in the right place.
