installing a turbo

[dbhittin 5,000+ posts]

the answer your looking for if bolting on a replacement turbo ect. 14b, 16g ect.. nothing it bolts right up.. anything else really, u will need to modify oil/water lines, ic piping ect

The 420a didn't come boosted... It's a ****ing Neon engine, crammed in the DSM to make it cheap. A 420a DSM runs a 16.6 in the 1/4, IIRC.

most NA engines can take some boost without problems. I dunno if 8psi is too much, I would guess 5psi but because it didnt come boosted doesnt mean you cant. Actually you can pull some serious numbers with that engine after you lower compression. No that engine did not ever come boosted factory. Not sure what the argument is here.

so much misinformation here. 19psi is the only one who seems to actually have first hand experience. he did a pretty good job of answering your question. if you have any more, try a performance forum instead of an audio one //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gifhttp://www.dsmtuners.com

i'm bored so i'll address a couple of the false claims:

1. every single thing lil_italy said was wrong.

2. nothing like a civic.

3. crankwalk was an issue in the 95-96 models. it was addressed and corrected. any car can crankwalk. it is not related to how much power the engine makes.

4. a 14b is a good upgrade but don't just turn up the boost without logging and knowing what you're doing, you'll melt a piston or spit a rod out real quick doing that. this is why dsm's have a bad rep.

5. the exhaust manifold has a mitsubishi flange. the stocker is good for quite a bit of power. tubular ones are useless for the most part and WILL crack.

6. your limits aren't going to be based on boost pressure alone. different turbos flow different amounts of air at a given pressure. there aren't set numbers on how much boost you can run safely. this is why you need to log and understand what you're looking at.

if you're coming on an audio forum and asking what you need to do to upgrade the turbo, don't touch anything turbo related, or adjust the boost. install an aftermarket boost gauge and stick to bolt-ons until you learn what you're doing, or you'll screw something up. some mods, even things as simple as exhaust piping, can have an effect on how much boost you're going to see so keep on eye on that. if you see it go higher than what it should, find out why and fix it.

there are plenty of dsmers on the internet willing to help you, but ask in the right place and don't be stupid about it, follow the recommended upgrade path that has been established and proven to work for over a decade.

close to a grand, 5000 over 2 years on all of it. u prob have v8 this is a 4cyl

the side mount intercooler is not rated for more that 15psi anymore and that will cause back pressure making huge turbo lag beside that the exhuast will not be as free flowin. and u will need a bigger oil pump more HP more oil is needed and bigger oil reaturn lines to the turbo back to oil pan ....as for the bigger injectors 650cc at the least....and u will need a mp senser over ride u just simply splice this in the wires so the compuer wont go ape shit with more boost than the computer is tuned for... u can have the computer dyno tuned for the increased fuel curve, but a full out computer from jet will be much better..bigger turbo needs a bigger exhuast manifold the flang on the bigger turbo wont match that little G18s. in most cases the bigger turbos will need a wastegate just in case of to much exhuast pressure witch will cuase the turbines to melt from excessive heat build up. ur gonna need a new head u get the air in u got to get it back out... im very doutful that the stock internals will handle a big amounts of boost,. ur gonna need a better clutch with that much more HP that other clutch will burn out stage 3 at least... there is more but not gonna evern go any ferther in to it....its alot more that ur thinkin u better look into it further i was a huge tuner and turboed ever turd burner i ever owned. i know what a pain in the *** they are.

to turbo it right and make it last u need all that "shit" let him do that in 2 month time it will be broke down. ive been there and ive learned a big lesson do it right or DONT!

what are u kidding those cheaper rings will break after time with to much pressure even thoe its a turbo and would need heavier valve springs or it will make the valves chatter. but maybe im thiking he wants to race the thing everyday and beat on it. i might be thinking over kill then. my fualt.

you rock!!!! i like your brand of stupid,please continue.

A new turbo isn't a bad idea you just need to know the limits. On a GSX or anything with the 4G63 you can go up to (I believe) 12psi and I think you need a t3/t4 flanged turbo or else you'll also need a new header.

this is just a taste of whats on team 2g.btw stock is 14psi.i need more batt.s for da bass!!!!

hey lil_stupidity773.......i make 445hp/434lbs of in your face with a stock block and head on my

91 galant vr4.i have had this motor for 2 years now and it still has 170com on all 4 cyl. now to

make this more interesting,i built it 2 years ago and it has vatozone piston rings and bearings in it and cost me 300 bucks to make it 500hp reliable.you really souldnt be giving advice to any one......

galant ran a 7.8@ 95mph and 11.9@ 120mph, i have a very crappy pic of my dyno graph ill post that in a sec. this is a non gutted 91 gr4 on a 17 year old motor.

you're right...shitty pic....can't see the curve well

 

[bastard dsm]

that guy dosnt have a clue and he is giving false info, im just saying that the factory motor is a beast and is not a honda that has to be built like a mofo. the link under the dyno sheet is my engine pic
