I have pics of an E30 with an RB25DET conversion . He didn't even have to change the engine mounts...unbelievable . By the way a GTIR is AWD not 4WD , there is a difference .
I'm a datsun fan but I'm unimpressed with these 1/4 mile times for the SR20 and FJ20. In the 90's I had a 1600 with a L18 that run 14.4 with DCOE45 webers, no turbo. A mate had a stripped down 1600 with a L20, DCOE45's, and run 13.8, again no turbo. Later I fitted a L18 with a TO4 blowing into twin SU's, 13.5 quarter. A lot to be said for the old L series engines.
sounds great, but blow-thru setups won't work with variable-venturi carbs like hitachi SU-type carbs . they need engine-side vacuum to operate the one moving part that modulates their fuel-metering system. if you just have to blow a T04B or the like into an L-series motor, you would want to use a box blowing one or more twin-choke carburetors. these carbs use air flow and throttle position to meter fuel. either setup you mentioned would be smoked by a stroked L21/22B, everything else being the same. you just can't beat the torque and compression boost you get from stroking, and when it becomes a game of turbos and torque, who needs a full-house crank, anyway?
Incorrect. SU's use the pressure difference between the inlet and butterfly sides of the piston to govern piston height. Its a closed system, above the piston is ducted to the downward side, and below the piston is ducted to the air cleaner side. The air cleaner side sees boost pressure. So we still see a pressure difference and the piston works as normal. The oil damper must be in place or its all goes weird. also need to boost modulate the fuel supply and feed boost pressure to the float bowl. All carbies are the same, they only need to see a pressure difference between the in and out to work. You can have 10 pounds boost going into the carb, and 9 pounds in the inlet manifold, that one pound difference will be all the carb needs to work correctly. SU's work well in a blow through system, I drove it like that as a street car for 2 years. Throttle response was great, I was getting 18 pounds boost and back then the car was untouchable on the street. Another variable venturi carb I later used was a varijet, a few holes to seal, but once sorted was a very smooth carbi.
She looks awesome. Nice work Mr. Congratulations!
Ahh yes, the old Fast 4s and Rotaries videos. Good stuff!
16-17 grand for a 1600 sr20det conversion and build......gosh I miss the early 90's!
'...miss the early 90's.' So do I. Good times, happy times at Eastern Creek.
Yeah cost me 10g for a s15 front cut and 5 g for front end in 2021
we used to get S14 front clips from a yard in wilmington cali for obscenely cheap prices
Back then, they were pretty good numbers in 1/4 mile run
Great car my dad worked for Datsun UK as a mechanic

It's a shame they never sold a 2 door version of the 1600/510 in Australia.
didn't they have 510 utes there?

you can't blow into SU-type carbs- they have to be naturally aspirated. nice try...
I always thought my 510's were fast,,, until I drove a V8.
Dope tweeter location
Dat Tepo Australia
dam this O.G god father sr20det's baddass
Put money in engine build,,,.
Brakes nah,,,,
Suspension? Who needs that?
weakest link in the e30 is the cv in the axles but i think it a good thing. easy to replace and cheaper then a diff or box.
You would think the weakest link was the commo clutch but that didnt fail. Amazing!
I remember i has this fast fours video lol. If ANYONE has a dato 1600 fs. Hmu. Nostalgia is killing me.
Old fj still sounds good
More!
its mexico?????
when drifting wasn't popular lol spin out
Sweat as.....
