thanks for all the info

the powerband to be that long, 3500 to 4000rpm, so the turbo has spooled to max set boost and holds to redline with 3.5k to 4k rev powerband i am guessing 3,5L 12v has 6500rpm rev limit standard? i see that graph goes to 7k rpm, on stock engine, no aftermarket head work/parts? i would be happy with ...

and will be mapped for 99octane pump fuel

im using a gt42 size turbo [hks] on a 2.6L already, as long as you change gear often you stay in the powerband [rb26 8300rpm limit], 'drag-lag' with 1st gear can be overcome by using a Nitrous window switch, ie u get N20 to get you off the line then its not needed untill the next standing start. it ...

just to make things easy ? i thought maybe the forum might have done this already?


i was mainly after the equivilent of

Garrett GT35 [0.8 and 1.0AR] , GT4088R [0.8A/R], GT42 [smallest version of gt42 1.0A/R)

i am yet to learn working out compressor maps ;)

Hi, do any holset turbos come with v-band instead of t3 or t4 flange's? which new ones [or only new one's?], and which ones i can find at a breakers? also is there a link someone can post up showing holset turbos to there garrett equivilent's ? like: hx35 = GTxx hx40 = GT hx52=GT xx etc etc cheers

while looking at wikipedia i noticed, the m30 3.5L has 2 versions with different compression, i dont want to use forged engine parts, yet anyway, so whats my best choice? and is the wikipedia info correct, i have posted it below:- one with 8:0 compression M30B34 (207hp+224 ft·lbf) MADE-1986 and one ...

so it is possible to make a e30 335i m30 3.5L 12v with a second hand holset hx40/50 with near 400rwhp standard internals with metal headgasket [i assume you guys use 12-15% transmission loss] ? 450 at the fly

400rwhp would be suffiecient, i want a project thrash-about for under £2-3000 I think you'll struggle to do that, especially as the base E30 will likely be tired and need uprated brakes, suspension, tyres etc. to cope with any such power hike, unless you almost blow your budget on a well fettled E3...

also - how much would i pay for- on average ebay/scrappy:

e36 m3 3L + 5speed manual box £
e36 m3 3.2L + 6speed manual box £

e?? m5_3.6 24v + g'box £
e?? m5_3.8 24v + g'box £

m30 3.5L 12v + manual box

and turbo manifolds, can you buy these £? or have to get them made ? [about £1000?]

thanks

400rwhp would be suffiecient, of course 800rwhp [then m5 I6] would be great. my skyline is my daily driver, so i want a project thrash-about for under £2-3000

btw, didnt know the holset hx40 was the baby range, looking for equivilent of garett gt4088r in holset form , hx52, hx52super?

i should add i don't mind fitting ARP2000 bolts for con-rods, head suds and ACL bearings, metal head gasket etc small money parts, but unless using an m3 or m5 engine dont want to spend on forged conrods/pistons/crank.

hi im quite new to the forum, after seeing some youtube vids i want a mental bmw for scrapyard parts money for my weekend abuser. always wanted the e30+325 mtech kit with: will the [m30] 3.5L 12 v engine fit in any e30 shell [is the 316 smaller than the 320+ ?] WITH ROOM for added holset hx40 turbo,...
