what is real h.p. gain in turboing VG?
i'm ignorant of this whole thing. i have the small VG30E "160" hp. with a few bolt-ons like a an exhaust system and CAI. so i may actually have about 170 or 175 (very maybe) hp. what more can be gleaned from the VG by turboing it? is 220 around the realistic number? and, if so, how much of that actually gets to the wheels? like, i have the 160 hp. stock. but probably something like only 130 of it makes road contact. yes?
also, does the VLSD of the VE series trannys account for the higher 190 benchmark?
and how about cams? should you swap that out, too, while you have the Z car block sitting in the garage?
help.

The VLSD trans helps distribute that power to the ground but doesnt make any more power for you.

I think he's asking what sort of HP numbers can realistically be expected from a Turbo'ed VG.
When you're planning to turbo, you can aspire to any realistic amount. Build your motor to handle the strain and get a turbo capable of boosting high enough and you'll see incredible HP numbers. 220 to the wheels isn't at all an unrealistic number, probably a low number if anything.

HP out of a modded engine all depends on what you want to put in it. there are people running 10+ psi on stock bottom ends putting out well over 300 WHEEL hp, but they've got custom programmed ECUs, big injectors, and fun stuff like that. it all depends on how much money you want to put into it.

thanks, you guyz
yes. i wanted to know what could be realistically put to the wheels after turboing the VG. what i really need is a more comprehensive study of how to actually do it, as there is so much scattered info about it. i will search the "stickies" thing, i guess. is there a compiled VG turbo "faq" thing available? i really want to do this right. and i'm green about it. i bought a book on turbos, superchargers, and nitrous. so i'm learning lots of basics. but i need VG specifics at this point. i understand boost pressure terms, compression ratio and what is considered low and high, bore and stroke terms, "volumetric efficiency," etc.
anymore feedback on this is wonderful. thanks everyone.

in that case, buy a service manual and take the bore, stroke, compression, etc numbers from it and start crunching numbers.
the rest of it is completely custom. you know what parts you need to do it, and you have xxx amount of room under the hood. now the job is to start gluing the stuff together until it works. and don't turn the boost control **** too far.

this is how to swap in the VG30ET, but it basically applies to the turboing the VG as well give or take some info. putting the motor into the car and getting the parts made is the easy part...after that its the little things like finding fittings, figuring out Z31 and Max sensors and having to fabricate random **** you never thought you'd need that makes you bang your head on the wall!![BangHead](https://maxima.org/forums/images/smilies/banghead.gif)

Re: what is real h.p. gain in turboing VG?
From the dyno's I've seen at Z31.com a stock turbo with a manual tranny should do around 160-170whp. Given intake, exhaust and 10-12psi of boost the car should make between 200-215whp. The highest dyno I've seen on the stock turbo was 249rwhp, that was with JWT ECU + NISMO cams along with intake, exhaust, 13-15psi. The most I've seen a stock VG dyno is around 125-135whp. With bolt ons like intake, exhaust, headers it would do around 140-148whp. With cams it easily does 150-159whp. Add headwork + more agressive cams and you'll dyno around 160-168whp.

..."With cams it easily does 150-159whp. Add headwork + more agressive cams and you'll dyno around 160-168whp..."
yes. i hear that. now. my mission is to do it up from the the inside out. i want to replace nearly everything necessary. i will not be bent on keeping much of it stock. (unless it is not necessary in some cases to change something). the main things that come to mind at this point are the valves, their cams, all headwork like ported and stuff, 3-angle valve, replace the main drive cam, get forged rods and pistons, even get a bigger turbo. i guy i know actually "ported" his inlet to his turbo on a skyline. so i just want to do it. i'd like to come up to the whp that the new G35 coupe puts out. they advert that to be "280 hp." but i bet it doesn't put that on the ground.

Re: turboing VG
If you going all out start with a VG33E. Get one from www.car-part.com that engine comes from a 96-99 pathfinder. Next you can go with custom 8.5cr pistons, DETT rods/crank, then get the headwork + cams. Otherwise just order a VG30ET and do the swap. The stock engine would handle over 400hp so you haven't much to worry about. If you did do the motorswap I suggest getting cams, new exhaust studs, new oil seals and a reprogrammed ECU. Also spend the money for a HKS or garrett BB GT series turbo.

turboing VG, maybe go with VG33E?
["]If you going all out start with a VG33E. Get one from www.car-part.com that engine comes from a 96-99 pathfinder."
hmmm. ok. what do you mean exactly? do you mean go with the 33E and keep it N/A? or turbo that one? what is the hp. benchmark for the 33E? this is very interesting to hear. please tell me more. this is getting good ----
