Starlet sr performance parts?

[jimjam]

Does anyone know where you can get upgraded parts for a sr as my friend is looking for uprated cams and loads of other parts. Cheers people!

[Matts]

Search around there's loads of answers around here Ryan Lang made a huge list some where for 4efe tuning consisted of loads of parts such as 5efhe cams and so forth if im correct

[jimjam]

Me and my friend have looked just seen air filters and useless stuff like that but my mate wants to make his sr silly fast without a turbo lol

[Flynn]

Don't waste your money..... Engine transplant is the way forward. Don't think silly fast is too achievable with an n/a, have a look at Morgeys 4age build, think he's managed pretty good bhp in his transplanted n/a! I've gone corolla inlet, 4-2-1 manifold, straight through de-cat and induction on my SR, a few people have gone further but dunno if they'd say all the money and effort was worth it? JDM 4efe engine revs a bit higher I think and corolla brown injectors will help if you can find any! Not much gains have been proven though!

[morgey]

Easiest n/a swap to do would be 5efhe. If you can find one. Then bolt ons flywheel head work n ecu, then strip the hell out of you car

With out going custom engine conversion 150 160ish bhp is about your limit imo

[jimjam]

Well he already has a glanza and it's gunna be a while till that's done and he wants to keep the sr engine in it but make it run more horse power, he mainly wants a set of cams but doesn't know where to get them from :/ does anyone know where to get them from???

[Billy SR]

corolla inlet

corolla 4-2-1 manifold

corolla yellow injections (are they even worth buying i don't know)

k&n panel filter

cat-back system

don't bother with the rest, an n/a is never gonna be quick. unless you drop a 5efe in.

focus on handling and brakes and save the real money for the glanza.

[ryan lang]

there is so much to do to these little engines, but unless your willing to go custom on a few parts and spend literally thousands upon thousands, then engine transplant is the way to go

and even with all the thousands spent, you'll be lucky to see 120-130bhp with mapping. ive always wanted to see a super charged n/a though, so if your mates got the dollar, definitely suggest that to him ;) lol

oh and this was the list:

N/A Performance List

Engine:
5EFHE cams (not 5EFE)
Lightened pulley sets
Head skim for compression
Ported head
Valve springs (there are some uprated valves springs for 4EFTE that can be used in the 4EFE. Eg: speedvision, cruise)

Exhaust:
4-2-1 corolla bugeye exhaust manifold
OBX racing 5e manifold
Hotshots 4e manifold (rocking horse shit, hens teeth etc)
Custom mani back exhaust (or cat-back)
Heatwrap

Fuelling:
Corolla bug eye injectors (beige/brown in color)
Fuel Pressure Regulator (to help with map)
After market Uprated Ignition leads
Spark plugs NGK heat range 6 or 7)
Could go coilpacks if going nuts but probably not needed)

Inlet:
Corolla bug eye inlet (tubular manifold)
4efte inlet manifold
4efte Throttle Body

Cooling:
Civic alloy dual/triple core radiator (personal preference on core)
Air filter (apexi is tried and tested, but whatever you can afford)
Low temp thermostat

Drive train:
Lightened flywheels (various after market ones available)
If you go for an off the shelf flywheel, you may need to buy the equivalent FTE clutch kit because the n/a lightened flywheels are really hard to come by
Corolla G6r 6 speed gearbox (requires shifter unit and cable mount brackets, possibly the actual selector cables) i may be wrong but its do-able
Lightened and balanced crank (if your going all out why not. should get the clutch and flywheel balanced at the same time as the crank)
LSD (they are available for the n/a 5 speed but rare. same as the 6speed. best off buying a glanza box and lsd if you dont go 6speed

Management:
Best way to go is aftermarket ecu, Emanage, Motec, Megasquirt etc (key modification to get the best out of these mods, if your going this crazy)

THEN to control all the gained power (probably only around 30bhp if your lucky)

Brakes:
Levin Twinpot callipers and corolla d4d discs (unsure if they are the correct discs, but there are enough people on here runnign sets to find out)
Celica st205 Twinpots (think they are the same as the levin twinpots)
Celica st185 big pot calliper (unsure on discs but will refer back to this when i do)
GT/Glanza carriers and disc's
Then there are the bigger aftermarket kits like wms, k-sport willwood etc. (bit overkill but if you like flashy then go for it)

Suspension/Chassis:
Whiteline adjustable rear anti-roll bar
Front and rear strut braces
Coilovers (dont go lowering springs if your buying for performance)
I found the c-pillar bar helped aswell
Anti lift kit
Uprated front anti-roll bar
Polybush engine mounts
Any other various strengthening bars

The biggest difference maker is weight saving. so what ever you dont need, get gone (rear seats, right through to smaller batteries and taking a dump before travelling etc)

AND MOST OF ALL: keep it serviced and looked after!

[AdamB]

Don't bother getting too hung up on cams, There not worth the money in terms of performance increase. It will only shift the power further up in the rev range and make it horrible to drive if going for too much duration.

Best thing to do is to get the engine to the highest possible compression ratio you can without the valves coming into contact with the pistons. Increase in power, and over the entire rev range.

Think mr Lang has got it covered for you there mate lol

There is aftermarket cams. I may have 5e-fhe cams for sale pretty soon.
