No Turbo!

Hey guys check it out who can tell me how to get some extra bang from a car without a turbo?

cams, Ecu, intakE, Extractors, exhaust, wheEL sizE, taking wEIght off the car i.e adding carbon fibEr parts, nos, aEro parts like a wing, or a supEr chargER but thats along the lines of turbo i guess

up until now u eh say which 4A-GE u have eh...1998 Sprinter GT will carry either a Blacktop or Silvertop 20V (tho I feel is a blacktop you'll have)..

it varies, how much u can squeeze out of either one without boosting it

YEAH IT'S A BLACKTOP 20V I HAVE! IT HAVE AH AE110 DOWN HERE WITH A TURBO KIT HE RUNNING 8 LBS BUT HE STILL CANT BEAT A GT COROLLA AND THATS WHAT HE WANTED IT FOR I FEEL SO SORRY FOR HIM.LOL

well what options have u explored so far?

in stock trim, once u get the required 100RON gas u supposed to be putting out 170horses at the flywheel...figure say 150-ish at the wheels if it's M/T and 140-ish if it's A/T...I may be wrong here

as far as bolt-on mods, CAI or a SRI and tuned exhaust headers, ignition upgrades..external, stand-alone or piggyback FMU (whichever tickles your pickle), a window switch can act as a VVT controller (or a piggyback system like a VAFC which incorporates the two)...HKS has an adjustable cam gear set and a pulley kit or the 20V as well

Nitrous, can be considered by some as a "chemical turbo" of sorts...so the N/A purists will oppose this, but it's an option...the quad throttles create the high possibility of starving the cylinders furthest away from the nitrous charge tho, and worse yet if u using velo stacks, so direct port injection is the most efficient way...do LOTS of research first

since it's blacktop and it's metering the intake via a MAP sensor, u can ditch the stock airbox and opt for some velocity stacks...some re-routing of the vacuum hoses for A/C and cold start idle-up is necessary, but not impossible

not much to do with internals really...Tom's/Toda/HKS cams are a nice addition..I believe Tom's has a complete valvetrain kit available...then there's the usual port and polish

but above all, octane is your main obstacle here buddy...there's little tuning things to be done with a stock 20V...MAF tweaking, timing and plugs and the piss gas we get at the pump will always keep it from reaching its potential...
do some research into water injection, I think it's a viable option to cool the intake charge and improve octane at the same time, BUT like nitrous, cylinder starvation is a concern as well...but you're a smart guy, you can come up with something Wink

well gt corolla's come around 160-175hp his regular corolla comes with 95hp he add on the turbo kit with 8lbs boost lets say 1lb giving you 5hp gain so he has 40hp gain all toghether he has 135hp much shy of a GT COROLLA.

it didnt make sense he turbo that

where he get manifold for that engine

my engine faster than his own

lol..I'm no mechanic...I read up and dig up in my ride just like anyone else on this forum Laughing

but there are boosted 4A-FE's all over that'll put a serious beating on ur GT eh..don't get cocky cuz ur buddy didn't do it correctly..there was one in Bim a while back that cranked out something like ~250hp at the wheels if I remember correctly

the 4A-FE can't take any fair amount of boost without internal work...let's say 6psi max without an intercooler and maybe 8psi with it....compression needs to be lowered, stonger pistons and con rods (say from a GZE), then there's the issue of fuel management, the flimsy 6bolt flywheel (I'd prefer an 8-bolt wheel for that kinda juice) and the econo crankshaft that likes to take a cool stroll when u play with ur redline too much Laughing

(and redline is only around 6300rpm or thereabouts)

if your buddy was doing the bulk of the work himself, then it'd prolly be worthwhile if parts are easy to come by...but to put that much time and effort into building a boosted 4A-FE monster isn't worth it IMO...he's better off working on a GZE

I know it got some serious 4a-fe around the place so much people told him he had more work to do on the car before he can really run them GT'S but he said once them hear the pssssst from his blow-off valve they will get scared he was wrond.LOL just gave them more drive to cut his ass.

^

the black top have a higher compressio ratio...S/T= 10.5:1....B/T=11:1

in the black top the connection rods are lighter...supposedly this allows the engine to rev higher easier and theyre supposed to be better balanced, but most cases have proven the ae101 (S|T)connection rods to be stronger

Also the silvertop ran on an AFM sensor, with the blacktop running on a MAP sensor.
