Need building advise

[untouchablecc]

I currently have a 6 bolt swap on stock compression (7:8.1) My mods list is all current except i do not have the smim anymore. I am trying to decide how to build this thing. My goal is 350 pump gas and maybe 400 if i can get there. The problem, this thing is fully spooled at almost 4000 rpm. Sure that is fun till about 6000 . I wanna bring that number down a lot.

Mods are

stock 6bolt arp mitsu multi layer gasket
bse and engine balance

Stage 2 shep trans
2600 clutch
fidanaza flywheel

ebay 16g (yeah i know im broke)

3in turbo back

27x7x 3in intercooler with short route
pressure tested to 15 psi with minimal leaks.

So is this common for spool time? How do other stock 1gs compare to this. My friend has a 1g i rode in an he has almost the same set up and his feels about the same on lag maybe not quite as bad.

My next mod will be a link an then start knocking down the fuel stuff.

So what am i doing wrong this thing sucks for around town driving. Should i go back to upgraded side mount, because i never plan on going over 400 with this set up because i want a healthy street set up with the best quarter mile times i can get out of that?

Any and all suggestions please.

4k?? that is high for a 16g. If I remember its around 3500-ish range.

I would first get a logger and log some data. This give a huge idea on what your car is doing. I would deffinately do link asap with fuel(pump, fpr, injectors). You have a setup that is ready for 12's all day.

4k does seem a bit high for a big 16g. I have a similar turbo and I see full boost at about 3.5k.

You can run a Big 16g on stock fuel, but you'll have to keep the boost low until you're able to scrape up enough for fuel mods AND(not OR) a logger. Get that fuel pump rewired and I'd say 12-13lbs can be done safely. But I wouldn't go any higher until you're able to log and see exactly what's going on.

And just some food for thought...

Careful with those "eBay Special" turbos.

If i get dsm link will i need a logger? Yeah i plan to get all the fuel mods and what not but i wanted to know what steps i can take at this point to make this thing spool well so once i get the good stuff it amplifies the effect. I plan to go gm mas i hear that helps out with spool. Would also a intake on the cold side of the turbo help spool. Porting an polishing increase spool? An i have the ability to get my i c pipes welded an just have a few couplers. I have thought about these things but i was not sure how much it would help at this point. Another thing i have thought about is on a side mount i love the spool its there its now. Draw back is making power on one. I doubt i will be able to make 350 pump gas hp with one of those no matter how large the side mount.

Also i do plan to get a real turbo one day but thank you for the advise.

I've read the ebay16gs spool quite a bit slower than mhi 16gs.
I would recommend getting a wideband when you get Link. You should be able to tune the spool down a bit. Also something that will help is porting your O2 housing if not done already. I would also port the inlet of turbine housing as well as collector, not that they will help spool as much as topend flow.
I would look into getting a real 16g. Look around you can find them cheap.
Obviously you will need fuel pump and injectors along with your other stuff. It will very hard to make 350whp without cams, too.

 

[untouchablecc]

I would like a mhi turbo i just dunno where to get one for a good price. And yeah i do want cams i realize most of the power in these engines stems from the head. I know there is various forums on porting i hate to sound dumb because i build all of my own cars but i am not sure what to use for porting. An jusmx told me i should use one of the ss o2 housings off ebay that there not bad. I will be doing another boost leak test tomorrow at my friends because i do not have a air compressor. Is it pretty cheap to port? I want a aem wideband i know i need one but it looks like dsm link will have to be first because of the money situation. Does anyone know if you can get 350 hp on side mounts without meth? Just curious.

Don't downgrade to a SMIC b/c you are getting crap spool from a crap turbo! I would keep the FMIC. It shouldn't be causing the problem. I have an ebay FMIC and run 28 psi with no issues.

Search "shimming the WG" or something similar. Maybe your flapper is hung open slightly like mine was. I had to shim the actuator on a brand new MHI Evo 16g because I didn't hit full boost until 4500rpm.

You can get a slightly used turbo from the classifieds here.

No you don't need a logger with DSMLink.

Port with a high quality carbide double-cut burr bit and a die grinder. I have had the same one for years and port a lot of sh_t.

your could port you exhuast manifold to help with spool.

There is articles for porting the manifold, housing,etc on VFAQ.com and some on this site.
Also your stock 2g O2 housing ported, should be plenty for your setup
Upgrading cams makes a big difference on our cars as they are not aggressive from the factory. Even the 264 & 272s still aren't huge cams by any means and work great for daily drivers

Alright im guessing the cams might help with spool? I thought a tune would prob help out more air more fuel to get that thing spinning. Hey that was a very valid point you made about the wg flapper being stuck open my1glaser. That has to be my issue because i have checked everything else right down to ignition timing to make sure i was not off an double checked it with a timing light. Alright well ill look into the porting here soon seems to be everyone agrees a getting rid of the fmic is a not so solid idea. An it seems that everyone else with one g compression seems to be happy with there spool time with a fmic so i prob need to look into this turbo a bit.
