Ok, my buddy and I where thinking of turboing his neon. 1gen neon. I dunno if its a sohc or dohc(included pic so you could see if you know(I can't remember). Well we where wondering how muchpsi we could run on the stock motor? I haven't been able to find anything about it. And has anyone done it that knows what kinda power it is putting down?



Don't worry, green is gone, rad support is being fixed and hood pins are being taken off(was like this when he got it)

 

If you have a back up car run10 psi ... but if not... stick with 5-7psi and the motor should be ok. ONLY if it is in proper running condition. Any small problems will become BIG problems. Searchy searchy, its on there.

 

thats a sohc...how many miles are on the car? if yall do decide to do turbo it....get a wideband a/f ratio....those other ones arent accurate and dont do anything but give you a good lighting show.

 

I did search, on here for about 15-20 minutes and on google for about the same amount of time, my search skills must suck then. Thanks for the info. Does anyone know on here if you need a stand alown fuel manigment system(like megasquirt)? I know with my car you do but have been told on different cars you don't.

Also, is there any good wrightups on a step by step or a thread with some good info? I am not new to turboing just on the neon.

O and thanks for the letting me know its a sohc, I thought so but the it has a dohc hood and its been awhile since I worked on the car. I'm not sure how many miles are on the motor, I know the kid that had it before and he had the motor rebuilt. The OD says about 150k, but I would say the motor had about 65-80k miles. He does have a backup car and we have another motor to be rebuilt(dohc) sitting in my garage, I told him to boost the hell out of the sohc and blow it up and built the dohc

 

theres kits for SOHC neons., the electronics and fuel delivery parts get expensive, you cant just stick a turbo on & go, you have to do the suppoting fuel and tuning upgrades to go with it.
belive me, i know.

I'd build up the spare DOHC he has and boost it. The turbo from a SOHC won't mount to the DOHC head.

You don't need a standalone, but you will have to block the MAP sensor from seeing boost. Although from the engine bay pic you provided, I would guess that its a 95, in which case you don't have to worry about the MAP sensor.

You can get a Hahn Reacecraft turbo setup or a cheaper way is the SRT-4 turbo setup. There is a sticky up top about the SRT-4 setup.

 

i know, I'm not thinking " O I can throw a turbo on from ebay with some pipes and its a race car!!" lol.

I know, more air= more fuel, if not more air =BOOM, lol

What I am wondering(like some cars) can you just upgrade the fuel pump and use a AFRP to adjust the fuel pressure. But some(like my mx6) you need a stand alown(megasquirt) in which you have to tune and such(which I want to try and avoid becouse of the pain in the *** it can be).

Any links to this kit?

 

Sweet, yes, it is a 95'( don't mind the picture, he bought it that way and we are both autobody graduates and are fixing that ugly/dirty probelm, lol). Also, that DEFFINETLY helps, but would I be farther ahead boosting the sohc(maybe building it) or the dohc(its from a 97 highline)? I know the dohc would probly make more power but what kinda problems would I have without the map sencer?

o and I seen the Hahn setup, that the one thats like $4,400? WAY to much cash, lol

What the motor looked like when he bought it:


Well he traded his 93' fox body mustang for it(4cyl) that didn't run right at all to a buddy of ours for this car(runs GREAT and needed it for work). It is getting a complete overhaul(18's, new bodykit, new doors, hood, roof skin, trunk lid, ect).

 

The MAP sensor doesn't like to see boost on the neons, but the 95's could care less. You get around the MAP sensor with either a MAP clamp or a missing link. The Hahn Stage II Turbo kit for the SOHC is about $3000, it thats too rich you can do the cheaper SRT-4 turbo build.

spudsterier on these boards has the SRT-4 setup on his R/T neon. The only difference is the SRT-4 turbo and exhaust manifold will not bolt up to the SOHC head. So now you have 2 more choices, swap to a DOHC head (same block) or get an $220 adapter plate from one source.

I know a guy who has his SOHC boosted with the stage II turbo from Hahn its very nice!!!! Excellent sleeper.

 

the hahn turbo kit runs about $2500.00
i just sold a hahn turbo and manifold on eaby the other day for $300.00, so it is a little easier to piece one together

if you use the dohc you can just get a map clamp.....
