Anyone Able To Help Me With Going Turb? Rb30

[JINSAY]

hey thanks for all your info, hahaha its given me about 10 hours to fully go through it all lol, but yeh my line is auto, witha pintara diff, full 25spine 2pinion 4.11, sadly hahaha and engine and box only done 170xxx and owned by an old girl so its all next to near perfect in that sense, i was thinking getting vl gear and peicing up my puzzle, i know basic mechanic stuff but a conversion is way outa my legue, so me mechanic would be doing it all for me..

Sell it and buy one already turbo, work out MUCH cheaper and will almost certainly be a better car.

Don't keep it because of sentimental value or you want to do all the mods yourself or some bs, trust me it is a waste of cash and you will regret it.

[JINSAY]

hahaha i see what your saying but this cars internals and externals are either full worked or just perfect, proud to say not one dint/scratch lol

VL Turbo gear would be the easiest.

eBay manifolds rarely fit correctly, been there done that on my VL -_-

I turboed my VL with ebay gear and a darkhalf remap, worked well... for about 3 days...

Running a bit lean man. http://i64.photobucket.com/albums/h199/zoidbergmerc/Cars/sparkplug.jpg

Great learning experience though.

ahhaha jeez lol yeh i was thinking a stock vlt exhaust manifold? I'm not aiming for a high mount t4 13psi setup lol, 7psi would do me fine i reckon, and just go from there?

Make sure you factor into this a proper dyno tune with an ECU or the picture above is a real reality, especially if the fuel pump isn't up to the task.

[JINSAY]

yeh my mechanic has a vl turb ecu for me plus injectas and he said i'd have to buy a bosch one or something or rather, lol he has the details for the pump

[Rolls]

Good to hear, highly recommend intercooling it as well.

+1 to VLT gear and turbo your NA!

30E is 9.0CR aye?

response in the nigga! yes?

[JINSAY]

its a 1989 rb30e i think.. Lol now i just have to find some stuff lol and yeh i got a decomplate on standby aswell aparently it'll bring it down to 7.0:1 lol and i can get an exhuast easy enough i hope lol and yeh intercooler would be a bit harder lol

[Rolls]

7:1 is way too low, it'll f**k the squish zones and be a dog if you lower it that much. Just keep boost under 6-7psi and leave the stock head gasket. Make sure you intercool it and run it very rich ~10-11:1 and be very conservative on timing.

Better than decomp and tuning like a turbo motor imo.

If you find doing the above and it still won't take any boost without detonation then look at the decomp plate, imo you should be fine though.

You really need to intercool it, especially if you want to drive it in summer, think of it this way, a new motor and fixing everything will cost you more than the intercooler will, do it once do it properly.

yeah it doesn't sound right, must be like 1cm tall to do that.

[Simon-S14]

do what im doing

1X VL Rb30E in mint condition

add RB30ET turbo manifold + RB25 stock turbo (i got these for $300)

Rb20det injectors (cheap - free) bolt into stock rail position

Convert dizzy to CAS by using dead RB20 CAS

AU coil packs, wired as wasted spark

RB20 ignitor

RB20 engine loom and ECU, remapped

RB20 AFM

good for a torquy 180 rwkw and cost you dick all

[Rolls]

Take simons advice.

[Simon-S14]

yeah not even bothering with DOHC head.. the E+t will be juuuust fine

[Rolls]

What car simon?

[Simon-S14]

my 180sx practice car. whole car, with this motor package, coils, locked diff, and few other extras has cost me sub 2K.

[Rolls]

impressive

Stock headgasket will take more than 6-7 psi. Mines holding up to 17, making over 300kw and never had the head lifted.
