I've been a 4G63 fan for quite some time now. I had a GVR4 that ran low 12's 10 years ago but sold it to build a Nova. I was recently looking for a new daily driver and came across this car on craigslist (it was also posted F/S on here). The car had some questionable modifications at the time of purchase but nothing that wasn't easily correctable.
I have 3 tanks through the car now, first tank was 30.5 mpg, 2nd tank was nearly 32 mpg and the last tank was back down to 30 due to some traffic issues.
Here is a basic list of what it has:
4G63 swap
8.5:1 pistons
F5M33 tranny (with LSD) The gearing is still terrible with the short tires (195/50/15) Shift lever wasn't properly modified so I took care of that and shortened the throws by 20% in the process.
Clutchmasters clutch
16G (not sure if it is a small or big) It makes boost waaaay too fast for a FWD so I am thinking it has the 05h wheel
660 injectors
300 lph pump
SAFCII
2G intake pipe
EVO MAS with K&N cone filter (had a 2G maf and a POS HKS mushroom filter when I bought it)
2.5" intercooler piping (I just rerouted the cold side piping)
Bar & Plate FMIC
Greddy BOV (rerouted)
Blitz boost controller
Greddy boost gauge (ordered a Autometer peak/hold with warning)
Autometer wideband is also on the way with peak/hold and warning (reads all the way down to 6:1 for the possibility of E85 later)
272 cams
Ported head
MSD wires
7ES plugs (need to gap them I'm sure)
2.5" downpipe - 3" catback
What looks to be an ebay tubular exhaust manifold
'90 oil filter housing with external cooler
OZ racing 15x6 wheels
mismatched 195/50/15 tires (shopping for wheels/tires now) I am going to flare the fenders and try to stuff a 235 in there
GR2 struts
Not sure what springs are on it. They are tagged with a part# I just need to write it down and do some searching.
You should note the absence of a fuel pressure regulator. The car is pig rich right now so I am actually hopeful I can get up to 35 mpg once it is properly tuned.
I spent the last few days reworking the cold side intercooler pipes. I was able to reuse some of the existing pipes so this didn't cost anything but my time. Actually, I did cut up the stock 2G throttle body adapter and welded on a 2.5" inlet from one of the unused pipes. I didn't take any pics of how it was before but I eliminated 4 bends and made enough room in the engine compartment to actually mount the air filter where it belongs. Previous owner also had the BOV on the hot side pipe which was corrected.
It needs engine mounts something fierce. I have a friend that works at Energy Suspension so that will be addressed shortly.
I am also on the hunt for a Colt grille and rear taillight insert. I found a grill on ebay last night and it happens to be red but it is chipped and IMO too expensive ($40).
The battery is ghetto mounted in the hatch. That will be addressed shortly. Honestly, that was the main reason why I rearranged the intercooler pipes because I was hoping I could fit the existing battery in that space.....NOT SO MUCH. I need to find a tiny battery like an Odyssey, Braille or equivalent to fit it under the hood.
There is an issue with the driver's side window motor and also seat belt tract. These issues were a little lower on the priority list.
Pile of aluminum pipes being eliminated one by one
Used some 1" wide aluminum bar to make a MAF bracket
The hot side pipe still bugs the hell out of me. What a terrible way to route that pipe. The thing had been dragging the ground and was in terrible shape. One of the clamps literally broke from being ground down so far. I replaced the clamps and the pipe with a steel piece. I'll eventually reroute the piping around the driver's side of the radiator but that will have to be done at the same time as a compressor housing upgrade that has an outlet pointing that direction.
