330 turbo,charger or nitrous?

[johnmaccow]

I will be getting my rolling shell in next few weeks which is a gold 2 door so going down the sleeper route .
I have a m52 2.8 engine(and box)which I will be doing the 330 crank and pistons swap along with the m50 inlet and bbtb.
Question is would it be best to turbo,supercharge or nitrous? Iam not bothered about economy and am leaning towards supercharging but not sure which route to take?
Also would it be best to stick with the box I have or is there a better one for acceleration?I will be fitting a LSD but also unsure which to get.I will be building it in the new year after my wedding so will have some money to throw at it .

Dont use the M52 ally lump if your after any seroius power, and car to be taken with stripping the threads out of the block when torquing the head down too.

Nitrous is rented horsepower.
The gains are impressive when set against the costs, but the power is only there as long as your gas lasts.....and that's never going to be long enough. Also don't just look at the numbers when deciding between supercharging and turbocharging. Depending on how much power you're aiming for going down each route could create two very different cars in the way they perform.

Think the way for me will be supercharging, instant power and possibly more reliable than turbo. Just love the idea of a standard looking gold e30 with 318i on back with a bit of a surprise when needed.Does anyone know what diff would be best for acceleration with the m52 engine and box?

plastic manifold and nos might not be the best idea lol.seen a plastic intercooler and manifold blow up on nos

Nozzles should be fitted as close to the port as possible to avoid this, same as lpg

I was told a while ago (well years ago), not to mount the foggers too close to the head,
(direct port fitment)
due to the extreme coldness of the nitrous oxide, as it would cause problems with the valves,
e.g going from engine temp to near enough "sub zero"
it could end up damaging or even worse, shattering the valves,

the foggers on my M20 2.7 (at the mo) are about 5 inches away from the cylinder head, just above the cast mark on the inlet manifold,
i was told to put them a few inches away from the head for the reasons above and also
so the nitrous/fuel/air would get a GOOD mixture before it entered the chamber,

i'll be looking in to how to mount them in a plastic inlet manifold at some point
due what dips has said has just got me worried a little bit






















Pahhhhhh i'm sure it'll be fine

There is such a thing as a plastic I/C ?

[Supafly]

Think he means one with plastic end caps

[ross_jsy]

Ah like the standard one on an R5....strapped a giant jubilee clip round mind to take more boost

We used to do that to Cosworths. Get a metal bander and put a couple around the IC to keep its end caps on.
